We need this so the next `lda #2` pushes 1 byte - (matching what `plb` expects to pop). Calling-convention - prologues always run in M=0 (16-bit), so this `sep` is - required. +This still works but is **no longer needed** for new code. Prefer the +direct 24-bit pointer form (`*(volatile int *)0x025000 = x;`) — it's +clearer, requires no inline asm, and produces fewer instructions +because the bank byte is encoded inline. -2. **`.byte 0xa9,0x02`** — raw bytes for `lda #$02`. We hand-encode - because llvm-mc can't yet emit an 8-bit immediate `lda #$02` - that knows it's 1 byte; the assembler keeps treating it as - 16-bit. `0xa9` is the LDA-immediate opcode; `0x02` is the - 1-byte operand. Result: A = `$02` (8-bit). +There's still one case where it's useful: if you have a *large amount* +of data work in a single bank and want every store to be 3 bytes +(`sta $5000,X` etc.) instead of 4 bytes (`sta long $025000,X`). In +that case, set DBR once with the helper above and use 16-bit-absolute +addresses afterward. Otherwise, the direct form is simpler. -3. **`pha`** — pushes A. In M=1 mode, PHA pushes exactly 1 byte - (the low half of A). Stack now has `$02` on top. +### What never needs bank-switching -4. **`plb`** — pops 1 byte from the stack and stores it in DBR. - DBR is now `$02`. All subsequent data accesses go to bank 2. +- **Local variables on the stack** — stack-relative accesses bypass DBR. +- **Direct-page accesses** — `lda $D0` always reads `$00:00D0`. +- **`[dp],Y` indirect-long pointers** — they carry their own bank byte. +- **Function calls** — `jsl` uses PBR + a long destination. +- **Pointers in ptr32 mode** — every C pointer is 32 bits, so deref'ing + any pointer (even one to bank 0) generates DBR-independent code. -5. **`rep #0x20`** — clears the `M` bit.

Once -`switchToBank2()` returns, all data reads/writes in your program -target bank 2 — until you switch DBR again. - -#### When you need it - -You need to switch DBR whenever you want to access data at an -absolute address `$XXXX` and need it to land in a specific bank. -Common cases: - -- **MMIO from the test harness** — `*(volatile uint16 *)0x5000 = x;` - Without DBR=2, this would go to bank 0's `$5000` (which is in - the language card area).

DP is anchored to bank 0. -- **Indirect-long pointers via `[dp],y`** — these include their - own bank byte and ignore DBR. -- **Function calls** — `jsl` uses PBR + a long destination - address. PBR is updated automatically. - -#### Other ways to access non-bank-0 data - -If you only need to write to a single non-bank-0 address, you can -emit the store as `STA_Long` (24-bit absolute) which encodes the -bank inline: - -```c -*(volatile unsigned short *)0x025000 = 42; // becomes sta $025000 -``` - -The W65816 backend recognizes `const-int pointer + integer offset` -and lowers to `sta long` if the address has a bank byte. No -`switchToBank2()` needed. - -For frequent data work in a bank, switching DBR once and using -plain `sta $5000` (2 bytes) is smaller and faster than `sta $025000` -(4 bytes) per access. - -#### Caveats - -- **Save/restore is your problem.** `switchToBank2()` never - restores DBR. If your caller expected DBR=0, you've broken its - expectation. For long-running programs, that's usually fine - (you just set DBR=2 once and stay there). For toolbox calls, GS/OS - might assume DBR=0 — check the call's documentation. -- **The stack is in bank 0 regardless.** Don't try to put the - stack elsewhere; the 65816's stack-relative addressing modes - ignore DBR. -- **In M=1 mode, INTERRUPTS may behave differently.** The `sep` - affects A's width but not the bank-switching machinery itself. - Keep the sep/rep window short. -- **PBR vs DBR** are independent. Code execution stays where it - was; only data accesses change. - -#### How `runInMame.sh --check 0x025000=...` works - -The check address `0x025000` is a 24-bit address: bank `$02`, -offset `$5000`. The MAME Lua runner reads this byte (and the next -byte if you specify a 2-byte value) directly from physical RAM, -bypassing DBR entirely. So the convention is: - -1. Your program switches DBR to bank 2. -2. Your program writes its result to `*(volatile X *)0x5000`, - which becomes `sta $5000` — landing in bank 2 because of DBR. -3. MAME reads bank 2's `$5000` via the absolute 24-bit address. -4. The runner compares to your expected value. - -If you forget `switchToBank2()`, your store goes to the language -card area (bank 0's `$5000`), MAME's check reads bank 2's -unchanged `$5000` (likely `$00` or whatever was there), and the -test fails. - -## Examples - -### Hello, integer - -```c -__attribute__((noinline)) void switchToBank2(void) { - __asm__ volatile ( - "sep #0x20\n.byte 0xa9,0x02\npha\nplb\nrep #0x20\n" - ); -} - -int main(void) { - int x = 42; - switchToBank2(); - *(volatile int *)0x5000 = x; - while (1) {} -} -``` - -Build & run: - -```bash -clang --target=w65816 -O2 -c hello.c -o hello.o -link816 -o hello.bin --text-base 0x1000 \ - runtime/crt0.o runtime/libc.o runtime/libgcc.o hello.o -bash scripts/runInMame.sh hello.bin --check 0x025000=002a # 0x2a = 42 -``` +## Worked examples ### Recursion + printing ```c +// fib.c #include #include @@ -346,54 +521,211 @@ unsigned long fib(unsigned n) { return fib(n-1) + fib(n-2); } -__attribute__((noinline)) void switchToBank2(void) { - __asm__ volatile ( - "sep #0x20\n.byte 0xa9,0x02\npha\nplb\nrep #0x20\n" - ); -} - int main(void) { char buf[32]; int len = snprintf(buf, sizeof buf, "fib(10) = %lu", fib(10)); - switchToBank2(); - // Copy buf to $025000 so we can read it after the run + // Copy the formatted string into bank-2 RAM at $02:5000 so the + // MAME harness can read it back.

The high +two bytes carry the bank byte plus a pad byte; the low two carry the +in-bank offset. This lets a single C pointer reach any byte in the +IIgs's 24-bit address space. + +A pointer dereference has to read up to 24 bits of address to know +which bank to touch. The CPU's `[dp],Y` (indirect-long-Y, opcode +0xB7) reads a 24-bit pointer from a direct-page slot and uses it as +the effective address — three bytes wide, bank byte explicit. This +is the **safe default** path and it works regardless of where the +target memory lives. + +There are two optimizations layered on top of the default path. One +is **always on** and safe. The other is **opt-in via a flag** and +needs care. + +### Layer 1: constant-offset peeling (default on, always safe) + +When you write `s->c` for a struct field at offset `4`, the natural +code is "compute `s + 4`, then deref". Layer 1 recognizes that +`[dp],Y` already has a Y register that's added to the 24-bit pointer +on the deref — so instead of computing `s + 4` first, the backend +stages the **base pointer** at `$E0..$E2` and loads `Y = #4` for the +deref. Saves three instructions per struct-field access (the +`clc; adc #4; ...; adc #0` carry chain). + +A consecutive-access CSE peephole shares the `$E0/$E2` staging +between adjacent derefs of the same base, so `s->a + s->b + s->c + +s->d` stages once and emits four `ldy #K; lda [$E0],Y` pairs. + +There's nothing to enable or disable. This was a `+1%` Lua-wide +size win on its own. It's always-on because it's structurally +equivalent to the un-optimized code — the same 24-bit deref, just +with the offset folded into Y instead of pre-added to the pointer. + +### Layer 2: `-mllvm -w65816-dbr-safe-ptrs` (opt-in, unsafe if misused) + +The default `[dp],Y` deref needs three bytes of staging at `$E0..$E2` +because it reads a 24-bit pointer. Calypsi uses `lda (d,S),Y` +(opcode 0xB3, stack-rel-indirect-Y) for the same effect in ONE +instruction — but that opcode reads only **16 bits** of pointer. +The bank byte is implicit DBR. + +When you pass `-mllvm -w65816-dbr-safe-ptrs`, our backend uses the +same one-instruction path: it spills only the low 16 bits of the +pointer to a stack slot, sets Y to the offset, and emits +`lda (slot,S),Y` (or `sta (slot,S),Y`). Bank byte = whatever DBR +holds at runtime. + +Per-deref cost drops from ~5 instructions to 1. Lua 5.1.5 shrinks +by 20.6% with the flag on. + +**This is correct only when every pointer dereferenced in the TU +points to memory inside DBR's current bank.** Some examples: + +| Pointer | Bank? | Safe with the flag? | +|---|---|---| +| `malloc()` result | DBR's bank (crt0 sets DBR to load bank; malloc allocates from BSS heap there) | Yes | +| Global variable address | DBR's bank (linker puts globals in the load segment) | Yes | +| `&local_array[i]` in a stack frame | Bank 0 (stack is always bank 0) | Yes IF DBR is 0 (typical) | +| Pointer returned by GS/OS Loader | The Loader's bank (might differ from yours) | **No** — would miscompile | +| Pointer cast from a `0x010000+addr` integer literal in bank 1 | Bank 1 | **No** if DBR is not bank 1 | +| `&ROMVECTORS[0]` from `iigs/`-style headers | Various IIgs system banks | **No** in general | + +For Lua, Picol, plain C programs that allocate via `malloc` and +operate on globals, this flag is safe. For GS/OS demos that interact +with Loader-returned segments or system memory, it would miscompile. + +Default is **off**. Opt in per-TU: + +```bash +clang --target=w65816 -O2 -mllvm -w65816-dbr-safe-ptrs -c hot.c -o hot.o +``` + +If you set the flag and your code does dereference cross-bank +pointers, the symptom is silent wrong-address reads — typically a +read from the same in-bank offset but in DBR's bank instead of the +intended one. No abort, no diagnostic. + +**Mixing safely:** the flag is per-TU. You can compile your hot +struct-heavy code with the flag and your bank-aware code without. +The two `.o` files link cleanly together. Per-function or +per-parameter control isn't supported yet. + +#### When the slot offset overflows 8 bits + +`lda (d,S),Y` has an 8-bit `d` field — max slot offset 255 from SP. +If the function's frame is large enough that the spill slot exceeds +that, PEI emits a fallback sequence that long-indirects the slot via +`[$F6],Y` (the function's frame-pointer), then stages at `$E0..$E2` +and derefs via `[$E0],Y`. This is ~8 instructions — worse than the +plain `[dp],Y` path the flag was meant to replace. Functions that +hit this need `usesDpFP=true` (set automatically for large frames); +otherwise PEI emits a fatal error. In practice you'll only see this +on functions with hundreds of local variables. + +### Inline-threshold tuning (default lowered to 50) + +LLVM's default inline-cost threshold is 225, tuned for desktop CPUs +where call overhead is high relative to the size of the inlined body. +On W65816 a `jsl long:foo` is just 4 bytes / ~8 cycles, but every +inlined pointer dereference expands to multiple instructions even +with Layer 2. Aggressive inlining bloats code without commensurate +cycle wins. + +The W65816 backend lowers the default to **50**. Calibration: + +| Threshold | Lua size | CoreMark size | Cycle benches | +|----------:|---------:|--------------:|--------------| +| 225 (LLVM stock) | 1.47× Calypsi | (not measured) | baseline | +| 75 | 1.16× | 0.87× | identical | +| **50 (current)** | **1.13×** | **0.79×** | identical | +| 25 | 1.11× | 0.79× | identical | + +At 225, Lua's `index2adr` (a multi-branch helper called 41 times in +`lapi.c`) was inlined into every API entry, adding ~2 KB per file — +and CoreMark's `matrix_test` was 17× Calypsi because the inliner +copied 5 nested-loop helpers into it. At 50, both regressions vanish +and the cycle benchmarks are unchanged. + +To override (e.g. on size-sensitive ROMs or speed-critical loops): + +```bash +# Force aggressive inlining (back to LLVM default) +clang --target=w65816 -O2 -mllvm -inline-threshold=225 -c file.c -o file.o + +# Force MORE conservative inlining +clang --target=w65816 -O2 -mllvm -inline-threshold=10 -c file.c -o file.o +``` + +A function marked `__attribute__((always_inline))` is always inlined +regardless of threshold.

All I/O and timing of the benchmark will be done through this layer. + +### Code / data size + +* Compile with gcc on x86 and make sure all sizes are according to requirements. +* If dynamic memory allocation is used, take total memory allocated into account as well. +* Avoid recursive functions and keep track of stack usage. +* Use the same memory block as data site for all algorithms, and initialize the data before each algorithm – while this means that initialization with data happens during the timed portion, it will only happen once during the timed portion and so have negligible effect on the results. + +## Controlled output + +This may be the most difficult goal. Compilers are constantly improving and getting better at analyzing code. To create work that cannot be computed at compile time and must be computed at run time, we will rely on two assumptions: + +* Some system functions (e.g. time, scanf) and parameters cannot be computed at compile time. In most cases, marking a variable volatile means the compiler is force to read this variable every time it is read. This will be used to introduce a factor into the input that cannot be precomputed at compile time. Since the results are input dependent, that will make sure that computation has to happen at run time. + +* Either a system function or I/O (e.g. scanf) or command line parameters or volatile variables will be used before the timed portion to generate data which is not available at compile time. Specific method used is not relevant as long as it can be controlled, and that it cannot be computed or eliminated by the compiler at compile time. E.g. if the clock() functions is a compiler stub, it may not be used. The derived values will be reported on the output so that verification can be done on a different machine. + +* We cannot rely on command line parameters since some embedded systems do not have the capability to provide command line parameters. All 3 methods above will be implemented (time based, scanf and command line parameters) and all 3 are valid if the compiler cannot determine the value at compile time. + +* It is important to note that The actual values that are to be supplied at run time will be standardized. The methodology is not intended to provide random data, but simply to provide controlled data that cannot be precomputed at compile time. + +* Printed results must be valid at run time. This will be used to make sure the computation has been executed. + +* Some embedded systems do not provide “printf” or other I/O functionality. All I/O will be done through a thin abstraction interface to allow execution on such systems (e.g. allow output via JTAG). + +## Key Algorithms + +### Linked List + +The following linked list structure will be used: + +~~~ +typedef struct list_data_s { + ee_s16 data16; + ee_s16 idx; +} list_data; + +typedef struct list_head_s { + struct list_head_s *next; + struct list_data_s *info; +} list_head; +~~~ + +While adding a level of indirection accessing the data, this structure is realistic and used in many embedded applications for small to medium lists. + +The list itself will be initialized on a block of memory that will be passed in to the initialization function. While in general linked lists use malloc for new nodes, embedded applications sometime control the memory for small data structures such as arrays and lists directly to avoid the overhead of system calls, so this approach is realistic. + +The linked list will be initialized such that 1/4 of the list pointers point to sequential areas in memory, and 3/4 of the list pointers are distributed in a non sequential manner. This is done to emulate a linked list that had add/remove happen for a while disrupting the neat order, and then a series of adds that are likely to come from sequential memory locations. + +For the benchmark itself: +- Multiple find operations are going to be performed. These find operations may result in the whole list being traversed. The result of each find will become part of the output chain. +- The list will be sorted using merge sort based on the data16 value, and then derive CRC of the data16 item in order for part of the list. The CRC will become part of the output chain. +- The list will be sorted again using merge sort based on the idx value. This sort will guarantee that the list is returned to the primary state before leaving the function, so that multiple iterations of the function will have the same result. CRC of the data16 for part of the list will again be calculated and become part of the output chain. + +The actual `data16` in each cell will be pseudo random based on a single 16b input that cannot be determined at compile time. In addition, the part of the list which is used for CRC will also be passed to the function, and determined based on an input that cannot be determined at run time. + +### Matrix Multiply + +This very simple algorithm forms the basis of many more complex algorithms. The tight inner loop is the focus of many optimizations (compiler as well as hardware based) and is thus relevant for embedded processing. + +The total available data space will be divided to 3 parts: +1. NxN matrix A. +2. NxN matrix B. +3. NxN matrix C. + +E.g. for 2K we will have 3 12x12 matrices (assuming data type of 32b 12(len)*12(wid)*4(size)*3(num) =1728 bytes). + +Matrix A will be initialized with small values (upper 3/4 of the bits all zero). +Matrix B will be initialized with medium values (upper half of the bits all zero). +Matrix C will be used for the result. + +For the benchmark itself: +- Multiple A by a constant into C, add the upper bits of each of the values in the result matrix. The result will become part of the output chain. +- Multiple A by column X of B into C, add the upper bits of each of the values in the result matrix. The result will become part of the output chain. +- Multiple A by B into C, add the upper bits of each of the values in the result matrix. The result will become part of the output chain. + +The actual values for A and B must be derived based on input that is not available at compile time. + +### State Machine + +This part of the code needs to exercise switch and if statements. As such, we will use a small Moore state machine. In particular, this will be a state machine that identifies string input as numbers and divides them according to format. + +The state machine will parse the input string until either a “,” separator or end of input is encountered. An invalid number will cause the state machine to return invalid state and a valid number will cause the state machine to return with type of number format (int/float/scientific). + +This code will perform a realistic task, be small enough to easily understand, and exercise the required functionality. The other option used in embedded systems is a mealy based state machine, which is driven by a table. The table then determines the number of states and complexity of transitions. This approach, however, tests mainly the load/store and function call mechanisms and less the handling of branches. If analysis of the final results shows that the load/store functionality of the processor is not exercised thoroughly, it may be a good addition to the benchmark (codesize allowing). + +For input, the memory block will be initialized with comma separated values of mixed formats, as well as invalid inputs. + +For the benchmark itself: +- Invoke the state machine on all of the input and count final states and state transitions. CRC of all final states and transitions will become part of the output chain. +- Modify the input at intervals (inject errors) and repeat the state machine operation. +- Modify the input back to original form. + +The actual input must be initialized based on data that cannot be determined at compile time. In addition the intervals for modification of the input and the actual modification must be based on input that cannot be determined at compile time. + +# Validation + +This release was tested on the following platforms: +* x86 cygwin and gcc 3.4 (Quad, dual and single core systems) +* x86 linux (Ubuntu/Fedora) and gcc (4.2/4.1) (Quad and single core systems) +* MIPS64 BE linux and gcc 3.4 16 cores system +* MIPS32 BE linux with CodeSourcery compiler 4.2-177 on Malta/Linux with a 1004K 3-core system +* PPC simulator with gcc 4.2.2 (No OS) +* PPC 64b BE linux (yellowdog) with gcc 3.4 and 4.1 (Dual core system) +* BF533 with VDSP50 +* Renesas R8C/H8 MCU with HEW 4.05 +* NXP LPC1700 armcc v4.0.0.524 +* NEC 78K with IAR v4.61 +* ARM simulator with armcc v4 + +# Memory Analysis + +Valgrind 3.4.0 used and no errors reported. + +# Balance Analysis + +Number of instructions executed for each function tested with cachegrind and found balanced with gcc and -O0. + +# Statistics + +Lines: +~~~ +Lines Blank Cmnts Source AESL +===== ===== ===== ===== ========== ======================================= + 469 66 170 251 627.5 core_list_join.c (C) + 330 18 54 268 670.0 core_main.c (C) + 256 32 80 146 365.0 core_matrix.c (C) + 240 16 51 186 465.0 core_state.c (C) + 165 11 20 134 335.0 core_util.c (C) + 150 23 36 98 245.0 coremark.h (C) + 1610 166 411 1083 2707.5 ----- Benchmark ----- (6 files) + 293 15 74 212 530.0 linux/core_portme.c (C) + 235 30 104 104 260.0 linux/core_portme.h (C) + 528 45 178 316 790.0 ----- Porting ----- (2 files) + +* For comparison, here are the stats for Dhrystone +Lines Blank Cmnts Source AESL +===== ===== ===== ===== ========== ======================================= + 311 15 242 54 135.0 dhry.h (C) + 789 132 119 553 1382.5 dhry_1.c (C) + 186 26 68 107 267.5 dhry_2.c (C) + 1286 173 429 714 1785.0 ----- C ----- (3 files) +~~~ + +# Credits +Many thanks to all of the individuals who helped with the development or testing of CoreMark including (Sorted by company name; note that company names may no longer be accurate as this was written in 2009). +* Alan Anderson, ADI +* Adhikary Rajiv, ADI +* Elena Stohr, ARM +* Ian Rickards, ARM +* Andrew Pickard, ARM +* Trent Parker, CAVIUM +* Shay Gal-On, EEMBC +* Markus Levy, EEMBC +* Peter Torelli, EEMBC +* Ron Olson, IBM +* Eyal Barzilay, MIPS +* Jens Eltze, NEC +* Hirohiko Ono, NEC +* Ulrich Drees, NEC +* Frank Roscheda, NEC +* Rob Cosaro, NXP +* Shumpei Kawasaki, RENESAS + +# Legal +Please refer to LICENSE.md in this repository for a description of your rights to use this code. + +# Copyright +Copyright © 2009 EEMBC All rights reserved. +CoreMark is a trademark of EEMBC and EEMBC is a registered trademark of the Embedded Microprocessor Benchmark Consortium. + diff --git a/tests/coremark/coremark-src/barebones/core_portme.c b/tests/coremark/coremark-src/barebones/core_portme.c new file mode 100644 index 0000000..30112ff --- /dev/null +++ b/tests/coremark/coremark-src/barebones/core_portme.c @@ -0,0 +1,157 @@ +/* +Copyright 2018 Embedded Microprocessor Benchmark Consortium (EEMBC) + +Licensed under the Apache License, Version 2.0 (the "License"); +you may not use this file except in compliance with the License. +You may obtain a copy of the License at + + http://www.apache.org/licenses/LICENSE-2.0 + +Unless required by applicable law or agreed to in writing, software +distributed under the License is distributed on an "AS IS" BASIS, +WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +See the License for the specific language governing permissions and +limitations under the License. + +Original Author: Shay Gal-on +*/ +#include "coremark.h" +#include "core_portme.h" + +#if VALIDATION_RUN +volatile ee_s32 seed1_volatile = 0x3415; +volatile ee_s32 seed2_volatile = 0x3415; +volatile ee_s32 seed3_volatile = 0x66; +#endif +#if PERFORMANCE_RUN +volatile ee_s32 seed1_volatile = 0x0; +volatile ee_s32 seed2_volatile = 0x0; +volatile ee_s32 seed3_volatile = 0x66; +#endif +#if PROFILE_RUN +volatile ee_s32 seed1_volatile = 0x8; +volatile ee_s32 seed2_volatile = 0x8; +volatile ee_s32 seed3_volatile = 0x8; +#endif +volatile ee_s32 seed4_volatile = ITERATIONS; +volatile ee_s32 seed5_volatile = 0; +/* Porting : Timing functions + How to capture time and convert to seconds must be ported to whatever is + supported by the platform. e.g. Read value from on board RTC, read value from + cpu clock cycles performance counter etc. Sample implementation for standard + time.h and windows.h definitions included. +*/ +CORETIMETYPE +barebones_clock() +{ +#error \ + "You must implement a method to measure time in barebones_clock()!

For other information (e.g. run rules) please see [README.md](README.md). + +## Definition of bare-bone systems + +The term bare-bones here mean systems that are bare minimum, and only provide the essential parts. A bare-bone processor system might not have an rich-OS (e.g. Linux, Windows), and in that case the system can also be referred as bare-metal. + +The bare-bones folder in the CoreMark repository provides the bare minimum to allow CoreMark to be ported to a processor system. As the code inside does not have any dependency on OS, it is the best starting point for porting CoreMark to a baremetal system where OS is not used, such as a microcontroller or an embedded processor. + +## Overview + +CoreMark can be used with microcontrollers / embedded processor devices. Before you start porting CoreMark, please setup a project environment that provides: + +- printf support +- timer support (e.g. base on a reference that has a constant clock frequency) + +The CoreMark execution needs to execute for at least 10 seconds. Therefore when selecting a timer peripheral for timing measurement, you need to ensure that the timer can measure the whole duration of the coremark execution. For example, let's say you are using a microcontroller and that has a 24-bit timer, and use the 24-bit timer as the timing reference. If the device is running at 100MHz and the timer is setup to run using the processor's clock, the longest time that the timer can count is 0.16777 second before it overflows or reaches zero. To measure the execution time, you could setup that timer to interrupt at a rate of 1KHz, and increment a counter variable inside the interrupt service routine. With this arrangement, there is some software overhead but the result should still be quite accurate. + +If the timer is 32-bit, and providing that: + +- the number of iterations is not too high, and +- the timer's frequency is not too high, + +then it is possible to measure the entire execution period without timer overflow/underflow. For example, if a 32-bit timer increment/decrement at 100MHz, it takes 42.95 seconds to overflow/underflow. So it is possible to use the timer's value directly if the execution time is between 10 to 42.95 seconds. + +You also need to estimate a minimum number of iterations before your start. The number of iterations can be set using a C preprocessing macro "ITERATIONS". For a processor with around 4 CoreMark/MHz and running at 100MHz, you need an iteration count of at least 4 (CoreMark/MHz) x100 (MHz) x 10 (seconds) = 4000 iterations. + +Incorrect timing reference is a common error, therefore, please test your timing measurement code. For example, by creating a small program that wait for 10 seconds and compare that to an external timing measurement tool (e.g. stopwatch). + +Once that are ready, you can then port the CoreMark project. The following files are required: + +- Source files that are used without modifications + - [coremark/core_main.c](https://github.com/eembc/coremark/blob/main/core_main.c) + - [coremark/core_list_join.c](https://github.com/eembc/coremark/blob/main/core_list_join.c) + - [coremark/core_matrix.c](https://github.com/eembc/coremark/blob/main/core_matrix.c) + - [coremark/core_state.c](https://github.com/eembc/coremark/blob/main/core_state.c) + - [coremark/core_util.c](https://github.com/eembc/coremark/blob/main/core_util.c) + - [coremark/coremark.h](https://github.com/eembc/coremark/blob/main/coremark.h) +- Source files that need modifications + - [coremark/barebones/core_portme.c](https://github.com/eembc/coremark/blob/main/barebones/core_portme.c) + - [coremark/barebones/core_portme.h](https://github.com/eembc/coremark/blob/main/barebones/core_portme.h) + + +And of course you need to include the support files for timer and printf support. + +In your project setup you also need to define pre-processing macros: + +| Preprocessing macro | Description / value | +|---|---| +|ITERATIONS| Set to the number of iterations the CoreMark workload will execute for at least 10 seconds. | +|STANDALONE| Set to indicate Standalone environment | +|PERFORMANCE_RUN / VALIDATION_RUN | Set to 1 | + +## Modifications of core_portme.h + +Several C macros require update: + +| Preprocessing macro | Value | +|---|---| +|HAS_FLOAT| 0 or 1 based on the processor/device| +|HAS_TIME_H| 0 | +|USE_CLOCK| 0 | +|HAS_STDIO| 1 | +|HAS_PRINTF| 1 | + +The next section in the file is dependent on the C compiler that you are using. The original code below utilizes compiler predefine macros for GCC **\_\_GNUC\_\_** and **\_\_VERSION\_\_** to provides printed message of compiler's version. (See [GCC documentation page](https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html) for additional information.) + +```C +#ifndef COMPILER_VERSION +#ifdef __GNUC__ +#define COMPILER_VERSION "GCC"__VERSION__ +#else +#define COMPILER_VERSION "Please put compiler version here (e.g. gcc 4.1)" +#endif +#endif +#ifndef COMPILER_FLAGS +#define COMPILER_FLAGS \ + FLAGS_STR /* "Please put compiler flags here (e.g. -o3)" */ +#endif +``` +You can insert additional compiler specific information using compiler predefine macros for the toolchain that you use. For example, information about LLVM predefined macros is available [here](https://clang.llvm.org/docs/LanguageExtensions.html#builtin-macros). + +And finally, set MAIN_HAS_NOARGC: + +```C +#ifndef MAIN_HAS_NOARGC +#define MAIN_HAS_NOARGC 1 +#endif +``` + +## Modifications of core_portme.c + +Note: The following codes are example. You can change the codes in other ways. + +In this file, first you might need to declare external functions for printf, timer and cache support. For example, in my project I declared the following external functions: + +```C +extern void timer_config(void); /* Initialize a timer peripheral */ +extern void stdio_init(void); /* Initialize printf support (e.g. UART) */ +extern void cache_init(void); /* Initialize processor's cache if available */ +extern unsigned long get_100Hz_value(void); /* Read a timer value with 0.01 sec resolution */ +``` + +Then I modified the barebones_clock() function as: + +```C +CORETIMETYPE +barebones_clock() +{ +/*#error \ + "You must implement a method to measure time in barebones_clock()! This function should return current time.\n" + */ + return get_100Hz_value(); +} +``` + +In this example, the timer value increments at 100Hz. So I need to tell the score calculation code with the following settings: + +```C +/* Define : TIMER_RES_DIVIDER + Divider to trade off timer resolution and total time that can be + measured. + + Use lower values to increase resolution, but make sure that overflow + does not occur. If there are issues with the return value overflowing, + increase this value. + */ +#define CLOCKS_PER_SEC 100 +#define GETMYTIME(_t) (*_t = barebones_clock()) +#define MYTIMEDIFF(fin, ini) ((fin) - (ini)) +#define TIMER_RES_DIVIDER 1 +#define SAMPLE_TIME_IMPLEMENTATION 1 +#define EE_TICKS_PER_SEC (CLOCKS_PER_SEC / TIMER_RES_DIVIDER) +``` + +Finally, the platform initialization code is updated as follow: + +```C +/* Function : portable_init + Target specific initialization code + Test for some common mistakes. +*/ +void +portable_init(core_portable *p, int *argc, char *argv[]) +{ + +/* #error \ + "Call board initialization routines in portable init (if needed), in particular initialize UART!\n" + + (void)argc; // prevent unused warning + (void)argv; // prevent unused warning +*/ + /* Hardware initialization */ + stdio_init(); + cache_init(); + timer_config(); + + if (sizeof(ee_ptr_int) != sizeof(ee_u8 *)) + { + ee_printf( + "ERROR! Please define ee_ptr_int to a type that holds a " + "pointer!\n"); + } + if (sizeof(ee_u32) != 4) + { + ee_printf("ERROR! Please define ee_u32 to a 32b unsigned type!\n"); + } + p->portable_id = 1; +} +``` + +## Additional considerations + +CoreMark demonstrate some performance aspects of the processors, but it might not reflect the performance of your applications in the real world. For example, the critical workloads in CoreMark does not contain floating-point operations, and is not data intensive. Also, because the memory footprint is quite small (This is necessary to allow CoreMark to be used in small, low-cost microcontrollers with limited memory sizes), when using CoreMark on a high-end processor system, the benchmark can easily fit into the level 1 caches and the performance of the memory system outside the L1 cache is not tested. [SPEC](https://spec.org) has other benchmarks that are suitable for testing the performance of high-end processor systems. + +If you are using a microcontroller with flash memory for program storage, and if the processor inside comes with Instruction and Data caches, in most cases you need to enable both I and D caches to get the best performance. This is because the program image contains both program instructions and constant data. + +Typically the CoreMark project fit within 32KB of ROM/flash and use less than 32KB of RAM. The stack and heap sizes inside the RAM is dependent on the processor architecture as well as the toolchain being used. For example, some toolchains could use more RAM for printf and floating-point library (Note: floating-point operations could be used for benchmark result calculation). In toolchains for typical 32-bit microcontrollers, usually the CoreMark uses less than 4KB of stack and 4KB of heap space. + +Many microcontroller vendors and some toolchain vendors provide application notes to explain to their customers how to setup CoreMark project to get the best performance. + + diff --git a/tests/coremark/coremark-src/core_list_join.c b/tests/coremark/coremark-src/core_list_join.c new file mode 100644 index 0000000..5d76b4d --- /dev/null +++ b/tests/coremark/coremark-src/core_list_join.c @@ -0,0 +1,595 @@ +/* +Copyright 2018 Embedded Microprocessor Benchmark Consortium (EEMBC) + +Licensed under the Apache License, Version 2.0 (the "License"); +you may not use this file except in compliance with the License. +You may obtain a copy of the License at + + http://www.apache.org/licenses/LICENSE-2.0 + +Unless required by applicable law or agreed to in writing, software +distributed under the License is distributed on an "AS IS" BASIS, +WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +See the License for the specific language governing permissions and +limitations under the License. + +Original Author: Shay Gal-on +*/ + +#include "coremark.h" +/* +Topic: Description + Benchmark using a linked list. + + Linked list is a common data structure used in many applications. + + For our purposes, this will excercise the memory units of the processor. + In particular, usage of the list pointers to find and alter data. + + We are not using Malloc since some platforms do not support this +library. + + Instead, the memory block being passed in is used to create a list, + and the benchmark takes care not to add more items then can be + accommodated by the memory block.

Variables

+ +

OUTFLAG

Use this flag to define how to to get an executable (e.g -o)

+ +

CFLAGS

Use this flag to define compiler options.  Note, you can add compiler options from the command line using XCFLAGS=”other flags”

+ +

LFLAGS_END

Define any libraries needed for linking or other flags that should come at the end of the link line (e.g. linker scripts).  Note: On certain platforms, the default clock_gettime implementation is supported but requires linking of librt.

+ +

SEPARATE_COMPILE

Define if you need to separate compilation from link stage.  In this case, you also need to define below how to create an object file, and how to link.

+ +

PORT_OBJS

Port specific object files can be added here

+ +

Build Targets

+ +

port_prebuild

Generate any files that are needed before actual build starts.  E.g. generate profile guidance files.  Sample PGO generation for gcc enabled with PGO=1

  • First, check if PGO was defined on the command line, if so, need to add -fprofile-use to compile line.
  • Second, if PGO reference has not yet been generated, add a step to the prebuild that will build a profile-generate version and run it.
NoteUsing REBUILD=1

Use make PGO=1 to invoke this sample processing.

+ +

port_postbuild

Generate any files that are needed after actual build end.  E.g. change format to srec, bin, zip in order to be able to load into flash

+ +

port_postrun

Do platform specific after run stuff.  E.g. reset the board, backup the logfiles etc.

+ +

port_prerun

Do platform specific after run stuff.  E.g. reset the board, backup the logfiles etc.

+ +

port_postload

Do platform specific after load stuff.  E.g. reset the reset power to the flash eraser

+ +

port_preload

Do platform specific before load stuff.  E.g. reset the reset power to the flash eraser

+ +

Variables

+ +

OPATH

Path to the output folder.  Defaultcurrent folder.
+ +

PERL

Description

Benchmark using a linked list.

Linked list is a common data structure used in many applications.

For our purposes, this will excercise the memory units of the processor.  In particular, usage of the list pointers to find and alter data.

We are not using Malloc since some platforms do not support this library.

Instead, the memory block being passed in is used to create a list, and the benchmark takes care not to add more items then can be accomodated by the memory block.  The porting layer will make sure that we have a valid memory block.

All operations are done in place, without using any extra memory.

The list itself contains list pointers and pointers to data items.  Data items contain the following:

idxAn index that captures the initial order of the list.
dataVariable data initialized based on the input parameters.  The 16b are divided as follows:
  • Upper 8b are backup of original data.
  • Bit 7 indicates if the lower 7 bits are to be used as is or calculated.
  • Bits 0-2 indicate type of operation to perform to get a 7b value.
  • Bits 3-6 provide input for the operation.
+ +

Functions

+ +

cmp_complex

ee_s32 cmp_complex(list_data *a,
list_data *b,
core_results *res)

Compare the data item in a list cell.

Can be used by mergesort.

+ +

cmp_idx

ee_s32 cmp_idx(list_data *a,
list_data *b,
core_results *res)

Compare the idx item in a list cell, and regen the data.

Can be used by mergesort.

+ +

core_list_init

list_head *core_list_init(ee_u32 blksize,
list_head *memblock,
ee_s16 seed)

Initialize list with data.

Parameters

blksizeSize of memory to be initialized.
memblockPointer to memory block.
seedActual values chosen depend on the seed parameter.  The seed parameter MUST be supplied from a source that cannot be determined at compile time

Returns

Pointer to the head of the list.

+ +

core_list_insert

list_head *core_list_insert_new(list_head *insert_point,
list_data *info,
list_head **memblock,
list_data **datablock ,
list_head *memblock_end,
list_data *datablock_end)

Insert an item to the list

Parameters

insert_pointwhere to insert the item.
infodata for the cell.
memblockpointer for the list header
datablockpointer for the list data
memblock_endend of region for list headers
datablock_endend of region for list data

Returns

Pointer to new item.

+ +

core_list_remove

list_head *core_list_remove(list_head *item)

Remove an item from the list.

Operation

For a singly linked list, remove by copying the data from the next item over to the current cell, and unlinking the next item.

Note

since there is always a fake item at the end of the list, no need to check for NULL.

Returns

Removed item.

+ +

core_list_undo_remove

list_head *core_list_undo_remove(list_head *item_removed,
list_head *item_modified)

Undo a remove operation.

Operation

Since we want each iteration of the benchmark to be exactly the same, we need to be able to undo a remove.  Link the removed item back into the list, and switch the info items.

Parameters

item_removedReturn value from the core_list_remove
item_modifiedList item that was modified during core_list_remove

Returns

The item that was linked back to the list.

+ +

core_list_find

list_head *core_list_find(list_head *list,
list_data *info)

Find an item in the list

Operation

Find an item by idx (if not 0) or specific data value

Parameters

listlist head
infoidx or data to find

Returns

Found item, or NULL if not found.

+ +

core_list_reverse

list_head *core_list_reverse(list_head *list)

Reverse a list

Operation

Rearrange the pointers so the list is reversed.

Parameters

listlist head
infoidx or data to find

Returns

Found item, or NULL if not found.

+ +

core_list_mergesort

list_head *core_list_mergesort(list_head *list,
list_cmp cmp,
core_results *res)

Sort the list in place without recursion.

Description

Use mergesort, as for linked list this is a realistic solution.  Also, since this is aimed at embedded, care was taken to use iterative rather then recursive algorithm.  The sort can either return the list to original order (by idx) , or use the data item to invoke other other algorithms and change the order of the list.

Parameters

listlist to be sorted.
cmpcmp function to use

Returns

New head of the list.

Note

We have a special header for the list that will always be first, but the algorithm could theoretically modify where the list starts.

Description

Matrix manipulation benchmark

This very simple algorithm forms the basis of many more complex algorithms.

The tight inner loop is the focus of many optimizations (compiler as well as hardware based) and is thus relevant for embedded processing.

The total available data space will be divided to 3 parts

NxN Matrix Ainitialized with small values (upper 3/4 of the bits all zero).
NxN Matrix Binitialized with medium values (upper half of the bits all zero).
NxN Matrix Cused for the result.

The actual values for A and B must be derived based on input that is not available at compile time.

Description

Simple state machines like this one are used in many embedded products.

For more complex state machines, sometimes a state transition table implementation is used instead, trading speed of direct coding for ease of maintenance.

Since the main goal of using a state machine in CoreMark is to excercise the switch/if behaviour, we are using a small moore machine.

In particular, this machine tests type of string input, trying to determine whether the input is a number or something else.  (see core_state).

Functions

+ +

get_seed

Get a values that cannot be determined at compile time.

Since different embedded systems and compilers are used, 3 different methods are provided

1Using a volatile variable.  This method is only valid if the compiler is forced to generate code that reads the value of a volatile variable from memory at run time.  Please note, if using this method, you would need to modify core_portme.c to generate training profile.
2Command line arguments.  This is the preferred method if command line arguments are supported.
3System function.  If none of the first 2 methods is available on the platform, a system function which is not a stub can be used.

e.g. read the value on GPIO pins connected to switches, or invoke special simulator functions.

Welcome

Copyright © 2009 EEMBC All rights reserved.  CoreMark is a trademark of EEMBC and EEMBC is a registered trademark of the Embedded Microprocessor Benchmark Consortium.

CoreMark’s primary goals are simplicity and providing a method for testing only a processor’s core features.

For more information about EEMBC’s comprehensive embedded benchmark suites, please see www.eembc.org.

+ +

Building and running

Download the release files from the www.coremark.org.  You can verify the download using the coremark_<version>.md5 file

md5sum -c coremark_<version>.md5

Unpack the distribution (tar -vzxf coremark_<version>.tgz && tar -vzxf coremark_<version>_docs.tgz) then change to the coremark_<version> folder.

To build and run the benchmark, type

make

Full results are available in the files run1.log and run2.log.  CoreMark result can be found in run1.log.

For self hosted Linux or Cygwin platforms, a simple make should work.

Cross Compile

For cross compile platforms please adjust core_portme.mak, core_portme.h (and possibly core_portme.c) according to the specific platform used.  When porting to a new platform, it is recommended to copy one of the default port folders (e.g. mkdir <platform> && cp linux/* <platform>), adjust the porting files, and run

make PORT_DIR=<platform>

Systems without make

The following files need to be compiled:

For example

gcc -O2 -o coremark.exe core_list_join.c core_main.c core_matrix.c core_state.c core_util.c simple/core_portme.c -DPERFORMANCE_RUN=1 -DITERATIONS=1000
+./coremark.exe > run1.log

The above will compile the benchmark for a performance run and 1000 iterations.  Output is redirected to run1.log.

Make targets

runDefault target, creates run1.log and run2.log.
run1.logRun the benchmark with performance parameters, and output to run1.log
run2.logRun the benchmark with validation parameters, and output to run2.log
run3.logRun the benchmark with profile generation parameters, and output to run3.log
compilecompile the benchmark executable
linklink the benchmark executable
checktest MD5 of sources that may not be modified
cleanclean temporary files

ITERATIONS

By default, the benchmark will run between 10-100 seconds.  To override, use ITERATIONS=N

make ITERATIONS=10

Will run the benchmark for 10 iterations.  It is recommended to set a specific number of iterations in certain situations e.g.:

  • Running with a simulator
  • Measuring power/energy
  • Timing cannot be restarted

Minimum required run time

Results are only valid for reporting if the benchmark ran for at least 10 secs!

XCFLAGS

To add compiler flags from the command line, use XCFLAGS e.g.

make XCFLAGS="-g -DMULTITHREAD=4 -DUSE_FORK=1"
  • CORE_DEBUG

Define to compile for a debug run if you get incorrect CRC.

make XCFLAGS="-DCORE_DEBUG=1"
  • Parallel Execution

Use XCFLAGS=-DMULTITHREAD=N where N is number of threads to run in parallel.  Several implementations are available to execute in multiple contexts, or you can implement your own in core_portme.c.

make XCFLAGS="-DMULTITHREAD=4 -DUSE_PTHREAD"

Above will compile the benchmark for execution on 4 cores, using POSIX Threads API.

REBUILD

To force rebuild, add the flag REBUILD to the command line

make REBUILD=1

Check core_portme.mak for more important options.

Run parameters for the benchmark executable

Coremark executable takes several parameters as follows (if main accepts arguments).  1st - A seed value used for initialization of data.  2nd - A seed value used for initialization of data.  3rd - A seed value used for initialization of data.  4th - Number of iterations (0 for auto : default value) 5th - Reserved for internal use.  6th - Reserved for internal use.  7th - For malloc users only, ovreride the size of the input data buffer.

The run target from make will run coremark with 2 different data initialization seeds.

Alternative parameters

If not using malloc or command line arguments are not supported, the buffer size for the algorithms must be defined via the compiler define TOTAL_DATA_SIZE.  TOTAL_DATA_SIZE must be set to 2000 bytes (default) for standard runs.  The default for such a target when testing different configurations could be ...

make XCFLAGS="-DTOTAL_DATA_SIZE=6000 -DMAIN_HAS_NOARGC=1"
+ +

Documentation

When you unpack the documentation (tar -vzxf coremark_<version>_docs.tgz) a docs folder will be created.  Check the file docs/html/index.html and the website http://www.coremark.org for more info.

+ +

Submitting results

CoreMark results can be submitted on the web.

Open a web browser and go to http://www.coremark.org- /benchmark- /index.php?pg=benchmark Select the link to add a new score and follow the instructions.

+ +

Run rules

What is and is not allowed.

Required

1The benchmark needs to run for at least 10 seconds.
2All validation must succeed for seeds 0,0,0x66 and 0x3415,0x3415,0x66, buffer size of 2000 bytes total.
  • If not using command line arguments to main:
make XCFLAGS="-DPERFORMANCE_RUN=1" REBUILD=1 run1.log
+make XCFLAGS="-DVALIDATION_RUN=1" REBUILD=1 run2.log
3If using profile guided optimization, profile must be generated using seeds of 8,8,8, and buffer size of 1200 bytes total.
make XCFLAGS="-DTOTAL_DATA_SIZE=1200 -DPROFILE_RUN=1" REBUILD=1 run3.log
4All source files must be compiled with the same flags.
5All data type sizes must match size in bits such that:
  • ee_u8 is an 8 bits datatype.
  • ee_s16 is an 16 bits datatype.
  • ee_u16 is an 16 bits datatype.
  • ee_s32 is an 32 bits datatype.
  • ee_u32 is an 32 bits datatype.

Allowed

  • Changing number of iterations
  • Changing toolchain and build/load/run options
  • Changing method of acquiring a data memory block
  • Changing the method of acquiring seed values
  • Changing implementation in core_portme.c
  • Changing configuration values in core_portme.h
  • Changing core_portme.mak

Not allowed

  • Changing of source file other then core_portme* (use make check to validate)
+ +

Reporting rules

How to report results on a data sheet?

CoreMark 1.0 : N / C [/ P] [/ M]

NNumber of iterations per second with seeds 0,0,0x66,size=2000)
CCompiler version and flags
PParameters such as data and code allocation specifics
  • This parameter may be omitted if all data was allocated on the heap in RAM.
  • This parameter may not be omitted when reporting CoreMark/MHz
MType of parallel execution (if used) and number of contexts This parameter may be omitted if parallel execution was not used.

e.g.

CoreMark 1.0 : 128 / GCC 4.1.2 -O2 -fprofile-use / Heap in TCRAM / FORK:2

or

CoreMark 1.0 : 1400 / GCC 3.4 -O4

If reporting scaling results, the results must be reported as follows

CoreMark/MHz 1.0 : N / C / P [/ M]

PWhen reporting scaling results, memory parameter must also indicate memory frequency:core frequency ratio.
  • If the core has cache and cache frequency to core frequency ratio is configurable, that must also be included.

e.g.

CoreMark/MHz 1.0 : 1.47 / GCC 4.1.2 -O2 / DDR3(Heap) 30:1 Memory 1:1 Cache

Also, have a look at the example programs in test. + +* Installing Lua + -------------- + Once you have built Lua, you may want to install it in an official + place in your system. In this case, do "make install". The official + place and the way to install files are defined in Makefile. You must + have the right permissions to install files. + + If you want to build and install Lua in one step, do "make xxx install", + where xxx is your platform name. + + If you want to install Lua locally, then do "make local".

NAME

+lua - Lua interpreter +

SYNOPSIS

+lua +[ +options +] +[ +script +[ +args +] +] +

DESCRIPTION

+lua +is the stand-alone Lua interpreter. +It loads and executes Lua programs, +either in textual source form or +in precompiled binary form. +(Precompiled binaries are output by +luac, +the Lua compiler.) +lua +can be used as a batch interpreter and also interactively. +

+The given +options +(see below) +are executed and then +the Lua program in file +script +is loaded and executed. +The given +args +are available to +script +as strings in a global table named +arg. +If these arguments contain spaces or other characters special to the shell, +then they should be quoted +(but note that the quotes will be removed by the shell). +The arguments in +arg +start at 0, +which contains the string +'script'. +The index of the last argument is stored in +arg.n. +The arguments given in the command line before +script, +including the name of the interpreter, +are available in negative indices in +arg. +

+At the very start, +before even handling the command line, +lua +executes the contents of the environment variable +LUA_INIT, +if it is defined. +If the value of +LUA_INIT +is of the form +'@filename', +then +filename +is executed. +Otherwise, the string is assumed to be a Lua statement and is executed. +

+Options start with +'-' +and are described below. +You can use +'--' +to signal the end of options. +

+If no arguments are given, +then +"-v -i" +is assumed when the standard input is a terminal; +otherwise, +"-" +is assumed. +

+In interactive mode, +lua +prompts the user, +reads lines from the standard input, +and executes them as they are read. +If a line does not contain a complete statement, +then a secondary prompt is displayed and +lines are read until a complete statement is formed or +a syntax error is found. +So, one way to interrupt the reading of an incomplete statement is +to force a syntax error: +adding a +';' +in the middle of a statement is a sure way of forcing a syntax error +(except inside multiline strings and comments; these must be closed explicitly). +If a line starts with +'=', +then +lua +displays the values of all the expressions in the remainder of the +line. The expressions must be separated by commas. +The primary prompt is the value of the global variable +_PROMPT, +if this value is a string; +otherwise, the default prompt is used. +Similarly, the secondary prompt is the value of the global variable +_PROMPT2. +So, +to change the prompts, +set the corresponding variable to a string of your choice. +You can do that after calling the interpreter +or on the command line +(but in this case you have to be careful with quotes +if the prompt string contains a space; otherwise you may confuse the shell.) +The default prompts are "> " and ">> ". +

OPTIONS

+

+- +load and execute the standard input as a file, +that is, +not interactively, +even when the standard input is a terminal. +

+-e stat +execute statement +stat. +You need to quote +stat +if it contains spaces, quotes, +or other characters special to the shell. +

+-i +enter interactive mode after +script +is executed. +

NAME

+luac - Lua compiler +

SYNOPSIS

+luac +[ +options +] [ +filenames +] +

DESCRIPTION

+luac +is the Lua compiler. +It translates programs written in the Lua programming language +into binary files that can be later loaded and executed. +

+The main advantages of precompiling chunks are: +faster loading, +protecting source code from accidental user changes, +and +off-line syntax checking. +

+Precompiling does not imply faster execution +because in Lua chunks are always compiled into bytecodes before being executed. +luac +simply allows those bytecodes to be saved in a file for later execution. +

+Precompiled chunks are not necessarily smaller than the corresponding source. +The main goal in precompiling is faster loading. +

+The binary files created by +luac +are portable only among architectures with the same word size and byte order. +

+luac +produces a single output file containing the bytecodes +for all source files given. +By default, +the output file is named +luac.out, +but you can change this with the +-o +option. +

+In the command line, +you can mix +text files containing Lua source and +binary files containing precompiled chunks. +This is useful because several precompiled chunks, +even from different (but compatible) platforms, +can be combined into a single precompiled chunk. +

+You can use +'-' +to indicate the standard input as a source file +and +'--' +to signal the end of options +(that is, +all remaining arguments will be treated as files even if they start with +'-'). +

+The internal format of the binary files produced by +luac +is likely to change when a new version of Lua is released. +So, +save the source files of all Lua programs that you precompile. +

+

OPTIONS

+Options must be separate. +

+-l +produce a listing of the compiled bytecode for Lua's virtual machine. +Listing bytecodes is useful to learn about Lua's virtual machine. +If no files are given, then +luac +loads +luac.out +and lists its contents. +

+-o file +output to +file, +instead of the default +luac.out. +(You can use +'-' +for standard output, +but not on platforms that open standard output in text mode.) +The output file may be a source file because +all files are loaded before the output file is written. +Be careful not to overwrite precious files. +

+-p +load files but do not generate any output file. +Used mainly for syntax checking and for testing precompiled chunks: +corrupted files will probably generate errors when loaded. +Lua always performs a thorough integrity test on precompiled chunks. +Bytecode that passes this test is completely safe, +in the sense that it will not break the interpreter. +However, +there is no guarantee that such code does anything sensible. +(None can be given, because the halting problem is unsolvable.) +If no files are given, then +luac +loads +luac.out +and tests its contents. +No messages are displayed if the file passes the integrity test. +

+-s +strip debug information before writing the output file. +This saves some space in very large chunks, +but if errors occur when running a stripped chunk, +then the error messages may not contain the full information they usually do. +For instance, +line numbers and names of local variables are lost. +

1 - Introduction

+ +

+Lua is an extension programming language designed to support +general procedural programming with data description +facilities. +It also offers good support for object-oriented programming, +functional programming, and data-driven programming. +Lua is intended to be used as a powerful, light-weight +scripting language for any program that needs one. +Lua is implemented as a library, written in clean C +(that is, in the common subset of ANSI C and C++). + + +

+Being an extension language, Lua has no notion of a "main" program: +it only works embedded in a host client, +called the embedding program or simply the host. +This host program can invoke functions to execute a piece of Lua code, +can write and read Lua variables, +and can register C functions to be called by Lua code. +Through the use of C functions, Lua can be augmented to cope with +a wide range of different domains, +thus creating customized programming languages sharing a syntactical framework. +The Lua distribution includes a sample host program called lua, +which uses the Lua library to offer a complete, stand-alone Lua interpreter. + + +

+Lua is free software, +and is provided as usual with no guarantees, +as stated in its license. +The implementation described in this manual is available +at Lua's official web site, www.lua.org. + + +

+Like any other reference manual, +this document is dry in places. +For a discussion of the decisions behind the design of Lua, +see the technical papers available at Lua's web site. +For a detailed introduction to programming in Lua, +see Roberto's book, Programming in Lua (Second Edition). + + + +

2 - The Language

+ +

+This section describes the lexis, the syntax, and the semantics of Lua. +In other words, +this section describes +which tokens are valid, +how they can be combined, +and what their combinations mean. + + +

+The language constructs will be explained using the usual extended BNF notation, +in which +{a} means 0 or more a's, and +[a] means an optional a. +Non-terminals are shown like non-terminal, +keywords are shown like kword, +and other terminal symbols are shown like `=´. +The complete syntax of Lua can be found in §8 +at the end of this manual. + + + +

2.1 - Lexical Conventions

+ +

+Names +(also called identifiers) +in Lua can be any string of letters, +digits, and underscores, +not beginning with a digit. +This coincides with the definition of names in most languages. +(The definition of letter depends on the current locale: +any character considered alphabetic by the current locale +can be used in an identifier.) +Identifiers are used to name variables and table fields. + + +

+The following keywords are reserved +and cannot be used as names: + + +

+     and       break     do        else      elseif
+     end       false     for       function  if
+     in        local     nil       not       or
+     repeat    return    then      true      until     while
+
+ +

+Lua is a case-sensitive language: +and is a reserved word, but And and AND +are two different, valid names. +As a convention, names starting with an underscore followed by +uppercase letters (such as _VERSION) +are reserved for internal global variables used by Lua. + + +

+The following strings denote other tokens: + +

+     +     -     *     /     %     ^     #
+     ==    ~=    <=    >=    <     >     =
+     (     )     {     }     [     ]
+     ;     :     ,     .     ..    ...
+
+ +

+Literal strings +can be delimited by matching single or double quotes, +and can contain the following C-like escape sequences: +'\a' (bell), +'\b' (backspace), +'\f' (form feed), +'\n' (newline), +'\r' (carriage return), +'\t' (horizontal tab), +'\v' (vertical tab), +'\\' (backslash), +'\"' (quotation mark [double quote]), +and '\'' (apostrophe [single quote]). +Moreover, a backslash followed by a real newline +results in a newline in the string. +A character in a string can also be specified by its numerical value +using the escape sequence \ddd, +where ddd is a sequence of up to three decimal digits. +(Note that if a numerical escape is to be followed by a digit, +it must be expressed using exactly three digits.) +Strings in Lua can contain any 8-bit value, including embedded zeros, +which can be specified as '\0'. + + +

+Literal strings can also be defined using a long format +enclosed by long brackets. +We define an opening long bracket of level n as an opening +square bracket followed by n equal signs followed by another +opening square bracket. +So, an opening long bracket of level 0 is written as [[, +an opening long bracket of level 1 is written as [=[, +and so on. +A closing long bracket is defined similarly; +for instance, a closing long bracket of level 4 is written as ]====]. +A long string starts with an opening long bracket of any level and +ends at the first closing long bracket of the same level. +Literals in this bracketed form can run for several lines, +do not interpret any escape sequences, +and ignore long brackets of any other level. +They can contain anything except a closing bracket of the proper level. + + +

+For convenience, +when the opening long bracket is immediately followed by a newline, +the newline is not included in the string. +As an example, in a system using ASCII +(in which 'a' is coded as 97, +newline is coded as 10, and '1' is coded as 49), +the five literal strings below denote the same string: + +

+     a = 'alo\n123"'
+     a = "alo\n123\""
+     a = '\97lo\10\04923"'
+     a = [[alo
+     123"]]
+     a = [==[
+     alo
+     123"]==]
+
+ +

+A numerical constant can be written with an optional decimal part +and an optional decimal exponent. +Lua also accepts integer hexadecimal constants, +by prefixing them with 0x. +Examples of valid numerical constants are + +

+     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56
+
+ +

+A comment starts with a double hyphen (--) +anywhere outside a string. +If the text immediately after -- is not an opening long bracket, +the comment is a short comment, +which runs until the end of the line. +Otherwise, it is a long comment, +which runs until the corresponding closing long bracket. +Long comments are frequently used to disable code temporarily. + + + + + +

2.2 - Values and Types

+ +

+Lua is a dynamically typed language. +This means that +variables do not have types; only values do. +There are no type definitions in the language. +All values carry their own type. + + +

+All values in Lua are first-class values. +This means that all values can be stored in variables, +passed as arguments to other functions, and returned as results. + + +

+There are eight basic types in Lua: +nil, boolean, number, +string, function, userdata, +thread, and table. +Nil is the type of the value nil, +whose main property is to be different from any other value; +it usually represents the absence of a useful value. +Boolean is the type of the values false and true. +Both nil and false make a condition false; +any other value makes it true. +Number represents real (double-precision floating-point) numbers. +(It is easy to build Lua interpreters that use other +internal representations for numbers, +such as single-precision float or long integers; +see file luaconf.h.) +String represents arrays of characters. + +Lua is 8-bit clean: +strings can contain any 8-bit character, +including embedded zeros ('\0') (see §2.1). + + +

+Lua can call (and manipulate) functions written in Lua and +functions written in C +(see §2.5.8). + + +

+The type userdata is provided to allow arbitrary C data to +be stored in Lua variables. +This type corresponds to a block of raw memory +and has no pre-defined operations in Lua, +except assignment and identity test. +However, by using metatables, +the programmer can define operations for userdata values +(see §2.8). +Userdata values cannot be created or modified in Lua, +only through the C API. +This guarantees the integrity of data owned by the host program. + + +

+The type thread represents independent threads of execution +and it is used to implement coroutines (see §2.11). +Do not confuse Lua threads with operating-system threads. +Lua supports coroutines on all systems, +even those that do not support threads. + + +

+The type table implements associative arrays, +that is, arrays that can be indexed not only with numbers, +but with any value (except nil). +Tables can be heterogeneous; +that is, they can contain values of all types (except nil). +Tables are the sole data structuring mechanism in Lua; +they can be used to represent ordinary arrays, +symbol tables, sets, records, graphs, trees, etc. +To represent records, Lua uses the field name as an index. +The language supports this representation by +providing a.name as syntactic sugar for a["name"]. +There are several convenient ways to create tables in Lua +(see §2.5.7). + + +

+Like indices, +the value of a table field can be of any type (except nil). +In particular, +because functions are first-class values, +table fields can contain functions. +Thus tables can also carry methods (see §2.5.9). + + +

+Tables, functions, threads, and (full) userdata values are objects: +variables do not actually contain these values, +only references to them. +Assignment, parameter passing, and function returns +always manipulate references to such values; +these operations do not imply any kind of copy. + + +

+The library function type returns a string describing the type +of a given value. + + + +

2.2.1 - Coercion

+ +

+Lua provides automatic conversion between +string and number values at run time. +Any arithmetic operation applied to a string tries to convert +this string to a number, following the usual conversion rules. +Conversely, whenever a number is used where a string is expected, +the number is converted to a string, in a reasonable format. +For complete control over how numbers are converted to strings, +use the format function from the string library +(see string.format). + + + + + + + +

2.3 - Variables

+ +

+Variables are places that store values. + +There are three kinds of variables in Lua: +global variables, local variables, and table fields. + + +

+A single name can denote a global variable or a local variable +(or a function's formal parameter, +which is a particular kind of local variable): + +

+	var ::= Name
+

+Name denotes identifiers, as defined in §2.1. + + +

+Any variable is assumed to be global unless explicitly declared +as a local (see §2.4.7). +Local variables are lexically scoped: +local variables can be freely accessed by functions +defined inside their scope (see §2.6). + + +

+Before the first assignment to a variable, its value is nil. + + +

+Square brackets are used to index a table: + +

+	var ::= prefixexp `[´ exp `]´
+

+The meaning of accesses to global variables +and table fields can be changed via metatables. +An access to an indexed variable t[i] is equivalent to +a call gettable_event(t,i). +(See §2.8 for a complete description of the +gettable_event function. +This function is not defined or callable in Lua. +We use it here only for explanatory purposes.) + + +

+The syntax var.Name is just syntactic sugar for +var["Name"]: + +

+	var ::= prefixexp `.´ Name
+
+ +

+All global variables live as fields in ordinary Lua tables, +called environment tables or simply +environments (see §2.9). +Each function has its own reference to an environment, +so that all global variables in this function +will refer to this environment table. +When a function is created, +it inherits the environment from the function that created it. +To get the environment table of a Lua function, +you call getfenv. +To replace it, +you call setfenv. +(You can only manipulate the environment of C functions +through the debug library; (see §5.9).) + + +

+An access to a global variable x +is equivalent to _env.x, +which in turn is equivalent to + +

+     gettable_event(_env, "x")
+

+where _env is the environment of the running function. +(See §2.8 for a complete description of the +gettable_event function. +This function is not defined or callable in Lua. +Similarly, the _env variable is not defined in Lua. +We use them here only for explanatory purposes.) + + + + + +

2.4 - Statements

+ +

+Lua supports an almost conventional set of statements, +similar to those in Pascal or C. +This set includes +assignments, control structures, function calls, +and variable declarations. + + + +

2.4.1 - Chunks

+ +

+The unit of execution of Lua is called a chunk. +A chunk is simply a sequence of statements, +which are executed sequentially. +Each statement can be optionally followed by a semicolon: + +

+	chunk ::= {stat [`;´]}
+

+There are no empty statements and thus ';;' is not legal. + + +

+Lua handles a chunk as the body of an anonymous function +with a variable number of arguments +(see §2.5.9). +As such, chunks can define local variables, +receive arguments, and return values. + + +

+A chunk can be stored in a file or in a string inside the host program. +To execute a chunk, +Lua first pre-compiles the chunk into instructions for a virtual machine, +and then it executes the compiled code +with an interpreter for the virtual machine. + + +

+Chunks can also be pre-compiled into binary form; +see program luac for details. +Programs in source and compiled forms are interchangeable; +Lua automatically detects the file type and acts accordingly. + + + + + + +

2.4.2 - Blocks

+A block is a list of statements; +syntactically, a block is the same as a chunk: + +

+	block ::= chunk
+
+ +

+A block can be explicitly delimited to produce a single statement: + +

+	stat ::= do block end
+

+Explicit blocks are useful +to control the scope of variable declarations. +Explicit blocks are also sometimes used to +add a return or break statement in the middle +of another block (see §2.4.4). + + + + + +

2.4.3 - Assignment

+ +

+Lua allows multiple assignments. +Therefore, the syntax for assignment +defines a list of variables on the left side +and a list of expressions on the right side. +The elements in both lists are separated by commas: + +

+	stat ::= varlist `=´ explist
+	varlist ::= var {`,´ var}
+	explist ::= exp {`,´ exp}
+

+Expressions are discussed in §2.5. + + +

+Before the assignment, +the list of values is adjusted to the length of +the list of variables. +If there are more values than needed, +the excess values are thrown away. +If there are fewer values than needed, +the list is extended with as many nil's as needed. +If the list of expressions ends with a function call, +then all values returned by that call enter the list of values, +before the adjustment +(except when the call is enclosed in parentheses; see §2.5). + + +

+The assignment statement first evaluates all its expressions +and only then are the assignments performed. +Thus the code + +

+     i = 3
+     i, a[i] = i+1, 20
+

+sets a[3] to 20, without affecting a[4] +because the i in a[i] is evaluated (to 3) +before it is assigned 4. +Similarly, the line + +

+     x, y = y, x
+

+exchanges the values of x and y, +and + +

+     x, y, z = y, z, x
+

+cyclically permutes the values of x, y, and z. + + +

+The meaning of assignments to global variables +and table fields can be changed via metatables. +An assignment to an indexed variable t[i] = val is equivalent to +settable_event(t,i,val). +(See §2.8 for a complete description of the +settable_event function. +This function is not defined or callable in Lua. +We use it here only for explanatory purposes.) + + +

+An assignment to a global variable x = val +is equivalent to the assignment +_env.x = val, +which in turn is equivalent to + +

+     settable_event(_env, "x", val)
+

+where _env is the environment of the running function. +(The _env variable is not defined in Lua. +We use it here only for explanatory purposes.) + + + + + +

2.4.4 - Control Structures

+The control structures +if, while, and repeat have the usual meaning and +familiar syntax: + + + + +

+	stat ::= while exp do block end
+	stat ::= repeat block until exp
+	stat ::= if exp then block {elseif exp then block} [else block] end
+

+Lua also has a for statement, in two flavors (see §2.4.5). + + +

+The condition expression of a +control structure can return any value. +Both false and nil are considered false. +All values different from nil and false are considered true +(in particular, the number 0 and the empty string are also true). + + +

+In the repeat–until loop, +the inner block does not end at the until keyword, +but only after the condition. +So, the condition can refer to local variables +declared inside the loop block. + + +

+The return statement is used to return values +from a function or a chunk (which is just a function). + +Functions and chunks can return more than one value, +and so the syntax for the return statement is + +

+	stat ::= return [explist]
+
+ +

+The break statement is used to terminate the execution of a +while, repeat, or for loop, +skipping to the next statement after the loop: + + +

+	stat ::= break
+

+A break ends the innermost enclosing loop. + + +

+The return and break +statements can only be written as the last statement of a block. +If it is really necessary to return or break in the +middle of a block, +then an explicit inner block can be used, +as in the idioms +do return end and do break end, +because now return and break are the last statements in +their (inner) blocks. + + + + + +

2.4.5 - For Statement

+ +

+ +The for statement has two forms: +one numeric and one generic. + + +

+The numeric for loop repeats a block of code while a +control variable runs through an arithmetic progression. +It has the following syntax: + +

+	stat ::= for Name `=´ exp `,´ exp [`,´ exp] do block end
+

+The block is repeated for name starting at the value of +the first exp, until it passes the second exp by steps of the +third exp. +More precisely, a for statement like + +

+     for v = e1, e2, e3 do block end
+

+is equivalent to the code: + +

+     do
+       local var, limit, step = tonumber(e1), tonumber(e2), tonumber(e3)
+       if not (var and limit and step) then error() end
+       while (step > 0 and var <= limit) or (step <= 0 and var >= limit) do
+         local v = var
+         block
+         var = var + step
+       end
+     end
+

+Note the following: + +

    + +
  • +All three control expressions are evaluated only once, +before the loop starts. +They must all result in numbers. +
    • + +
  • +var, limit, and step are invisible variables. +The names shown here are for explanatory purposes only. +
    • + +
  • +If the third expression (the step) is absent, +then a step of 1 is used. +
    • + +
  • +You can use break to exit a for loop. +
    • + +
  • +The loop variable v is local to the loop; +you cannot use its value after the for ends or is broken. +If you need this value, +assign it to another variable before breaking or exiting the loop. +
    • + +
+ +

+The generic for statement works over functions, +called iterators. +On each iteration, the iterator function is called to produce a new value, +stopping when this new value is nil. +The generic for loop has the following syntax: + +

+	stat ::= for namelist in explist do block end
+	namelist ::= Name {`,´ Name}
+

+A for statement like + +

+     for var_1, ···, var_n in explist do block end
+

+is equivalent to the code: + +

+     do
+       local f, s, var = explist
+       while true do
+         local var_1, ···, var_n = f(s, var)
+         var = var_1
+         if var == nil then break end
+         block
+       end
+     end
+

+Note the following: + +

    + +
  • +explist is evaluated only once. +Its results are an iterator function, +a state, +and an initial value for the first iterator variable. +
    • + +
  • +f, s, and var are invisible variables. +The names are here for explanatory purposes only. +
    • + +
  • +You can use break to exit a for loop. +
    • + +
  • +The loop variables var_i are local to the loop; +you cannot use their values after the for ends. +If you need these values, +then assign them to other variables before breaking or exiting the loop. +
    • + +
+ + + + +

2.4.6 - Function Calls as Statements

+To allow possible side-effects, +function calls can be executed as statements: + +

+	stat ::= functioncall
+

+In this case, all returned values are thrown away. +Function calls are explained in §2.5.8. + + + + + +

2.4.7 - Local Declarations

+Local variables can be declared anywhere inside a block. +The declaration can include an initial assignment: + +

+	stat ::= local namelist [`=´ explist]
+

+If present, an initial assignment has the same semantics +of a multiple assignment (see §2.4.3). +Otherwise, all variables are initialized with nil. + + +

+A chunk is also a block (see §2.4.1), +and so local variables can be declared in a chunk outside any explicit block. +The scope of such local variables extends until the end of the chunk. + + +

+The visibility rules for local variables are explained in §2.6. + + + + + + + +

2.5 - Expressions

+ +

+The basic expressions in Lua are the following: + +

+	exp ::= prefixexp
+	exp ::= nil | false | true
+	exp ::= Number
+	exp ::= String
+	exp ::= function
+	exp ::= tableconstructor
+	exp ::= `...´
+	exp ::= exp binop exp
+	exp ::= unop exp
+	prefixexp ::= var | functioncall | `(´ exp `)´
+
+ +

+Numbers and literal strings are explained in §2.1; +variables are explained in §2.3; +function definitions are explained in §2.5.9; +function calls are explained in §2.5.8; +table constructors are explained in §2.5.7. +Vararg expressions, +denoted by three dots ('...'), can only be used when +directly inside a vararg function; +they are explained in §2.5.9. + + +

+Binary operators comprise arithmetic operators (see §2.5.1), +relational operators (see §2.5.2), logical operators (see §2.5.3), +and the concatenation operator (see §2.5.4). +Unary operators comprise the unary minus (see §2.5.1), +the unary not (see §2.5.3), +and the unary length operator (see §2.5.5). + + +

+Both function calls and vararg expressions can result in multiple values. +If an expression is used as a statement +(only possible for function calls (see §2.4.6)), +then its return list is adjusted to zero elements, +thus discarding all returned values. +If an expression is used as the last (or the only) element +of a list of expressions, +then no adjustment is made +(unless the call is enclosed in parentheses). +In all other contexts, +Lua adjusts the result list to one element, +discarding all values except the first one. + + +

+Here are some examples: + +

+     f()                -- adjusted to 0 results
+     g(f(), x)          -- f() is adjusted to 1 result
+     g(x, f())          -- g gets x plus all results from f()
+     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
+     a,b = ...          -- a gets the first vararg parameter, b gets
+                        -- the second (both a and b can get nil if there
+                        -- is no corresponding vararg parameter)
+     
+     a,b,c = x, f()     -- f() is adjusted to 2 results
+     a,b,c = f()        -- f() is adjusted to 3 results
+     return f()         -- returns all results from f()
+     return ...         -- returns all received vararg parameters
+     return x,y,f()     -- returns x, y, and all results from f()
+     {f()}              -- creates a list with all results from f()
+     {...}              -- creates a list with all vararg parameters
+     {f(), nil}         -- f() is adjusted to 1 result
+
+ +

+Any expression enclosed in parentheses always results in only one value. +Thus, +(f(x,y,z)) is always a single value, +even if f returns several values. +(The value of (f(x,y,z)) is the first value returned by f +or nil if f does not return any values.) + + + +

2.5.1 - Arithmetic Operators

+Lua supports the usual arithmetic operators: +the binary + (addition), +- (subtraction), * (multiplication), +/ (division), % (modulo), and ^ (exponentiation); +and unary - (negation). +If the operands are numbers, or strings that can be converted to +numbers (see §2.2.1), +then all operations have the usual meaning. +Exponentiation works for any exponent. +For instance, x^(-0.5) computes the inverse of the square root of x. +Modulo is defined as + +

+     a % b == a - math.floor(a/b)*b
+

+That is, it is the remainder of a division that rounds +the quotient towards minus infinity. + + + + + +

2.5.2 - Relational Operators

+The relational operators in Lua are + +

+     ==    ~=    <     >     <=    >=
+

+These operators always result in false or true. + + +

+Equality (==) first compares the type of its operands. +If the types are different, then the result is false. +Otherwise, the values of the operands are compared. +Numbers and strings are compared in the usual way. +Objects (tables, userdata, threads, and functions) +are compared by reference: +two objects are considered equal only if they are the same object. +Every time you create a new object +(a table, userdata, thread, or function), +this new object is different from any previously existing object. + + +

+You can change the way that Lua compares tables and userdata +by using the "eq" metamethod (see §2.8). + + +

+The conversion rules of §2.2.1 +do not apply to equality comparisons. +Thus, "0"==0 evaluates to false, +and t[0] and t["0"] denote different +entries in a table. + + +

+The operator ~= is exactly the negation of equality (==). + + +

+The order operators work as follows. +If both arguments are numbers, then they are compared as such. +Otherwise, if both arguments are strings, +then their values are compared according to the current locale. +Otherwise, Lua tries to call the "lt" or the "le" +metamethod (see §2.8). +A comparison a > b is translated to b < a +and a >= b is translated to b <= a. + + + + + +

2.5.3 - Logical Operators

+The logical operators in Lua are +and, or, and not. +Like the control structures (see §2.4.4), +all logical operators consider both false and nil as false +and anything else as true. + + +

+The negation operator not always returns false or true. +The conjunction operator and returns its first argument +if this value is false or nil; +otherwise, and returns its second argument. +The disjunction operator or returns its first argument +if this value is different from nil and false; +otherwise, or returns its second argument. +Both and and or use short-cut evaluation; +that is, +the second operand is evaluated only if necessary. +Here are some examples: + +

+     10 or 20            --> 10
+     10 or error()       --> 10
+     nil or "a"          --> "a"
+     nil and 10          --> nil
+     false and error()   --> false
+     false and nil       --> false
+     false or nil        --> nil
+     10 and 20           --> 20
+

+(In this manual, +--> indicates the result of the preceding expression.) + + + + + +

2.5.4 - Concatenation

+The string concatenation operator in Lua is +denoted by two dots ('..'). +If both operands are strings or numbers, then they are converted to +strings according to the rules mentioned in §2.2.1. +Otherwise, the "concat" metamethod is called (see §2.8). + + + + + +

2.5.5 - The Length Operator

+ +

+The length operator is denoted by the unary operator #. +The length of a string is its number of bytes +(that is, the usual meaning of string length when each +character is one byte). + + +

+The length of a table t is defined to be any +integer index n +such that t[n] is not nil and t[n+1] is nil; +moreover, if t[1] is nil, n can be zero. +For a regular array, with non-nil values from 1 to a given n, +its length is exactly that n, +the index of its last value. +If the array has "holes" +(that is, nil values between other non-nil values), +then #t can be any of the indices that +directly precedes a nil value +(that is, it may consider any such nil value as the end of +the array). + + + + + +

2.5.6 - Precedence

+Operator precedence in Lua follows the table below, +from lower to higher priority: + +

+     or
+     and
+     <     >     <=    >=    ~=    ==
+     ..
+     +     -
+     *     /     %
+     not   #     - (unary)
+     ^
+

+As usual, +you can use parentheses to change the precedences of an expression. +The concatenation ('..') and exponentiation ('^') +operators are right associative. +All other binary operators are left associative. + + + + + +

2.5.7 - Table Constructors

+Table constructors are expressions that create tables. +Every time a constructor is evaluated, a new table is created. +A constructor can be used to create an empty table +or to create a table and initialize some of its fields. +The general syntax for constructors is + +

+	tableconstructor ::= `{´ [fieldlist] `}´
+	fieldlist ::= field {fieldsep field} [fieldsep]
+	field ::= `[´ exp `]´ `=´ exp | Name `=´ exp | exp
+	fieldsep ::= `,´ | `;´
+
+ +

+Each field of the form [exp1] = exp2 adds to the new table an entry +with key exp1 and value exp2. +A field of the form name = exp is equivalent to +["name"] = exp. +Finally, fields of the form exp are equivalent to +[i] = exp, where i are consecutive numerical integers, +starting with 1. +Fields in the other formats do not affect this counting. +For example, + +

+     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
+

+is equivalent to + +

+     do
+       local t = {}
+       t[f(1)] = g
+       t[1] = "x"         -- 1st exp
+       t[2] = "y"         -- 2nd exp
+       t.x = 1            -- t["x"] = 1
+       t[3] = f(x)        -- 3rd exp
+       t[30] = 23
+       t[4] = 45          -- 4th exp
+       a = t
+     end
+
+ +

+If the last field in the list has the form exp +and the expression is a function call or a vararg expression, +then all values returned by this expression enter the list consecutively +(see §2.5.8). +To avoid this, +enclose the function call or the vararg expression +in parentheses (see §2.5). + + +

+The field list can have an optional trailing separator, +as a convenience for machine-generated code. + + + + + +

2.5.8 - Function Calls

+A function call in Lua has the following syntax: + +

+	functioncall ::= prefixexp args
+

+In a function call, +first prefixexp and args are evaluated. +If the value of prefixexp has type function, +then this function is called +with the given arguments. +Otherwise, the prefixexp "call" metamethod is called, +having as first parameter the value of prefixexp, +followed by the original call arguments +(see §2.8). + + +

+The form + +

+	functioncall ::= prefixexp `:´ Name args
+

+can be used to call "methods". +A call v:name(args) +is syntactic sugar for v.name(v,args), +except that v is evaluated only once. + + +

+Arguments have the following syntax: + +

+	args ::= `(´ [explist] `)´
+	args ::= tableconstructor
+	args ::= String
+

+All argument expressions are evaluated before the call. +A call of the form f{fields} is +syntactic sugar for f({fields}); +that is, the argument list is a single new table. +A call of the form f'string' +(or f"string" or f[[string]]) +is syntactic sugar for f('string'); +that is, the argument list is a single literal string. + + +

+As an exception to the free-format syntax of Lua, +you cannot put a line break before the '(' in a function call. +This restriction avoids some ambiguities in the language. +If you write + +

+     a = f
+     (g).x(a)
+

+Lua would see that as a single statement, a = f(g).x(a). +So, if you want two statements, you must add a semi-colon between them. +If you actually want to call f, +you must remove the line break before (g). + + +

+A call of the form return functioncall is called +a tail call. +Lua implements proper tail calls +(or proper tail recursion): +in a tail call, +the called function reuses the stack entry of the calling function. +Therefore, there is no limit on the number of nested tail calls that +a program can execute. +However, a tail call erases any debug information about the +calling function. +Note that a tail call only happens with a particular syntax, +where the return has one single function call as argument; +this syntax makes the calling function return exactly +the returns of the called function. +So, none of the following examples are tail calls: + +

+     return (f(x))        -- results adjusted to 1
+     return 2 * f(x)
+     return x, f(x)       -- additional results
+     f(x); return         -- results discarded
+     return x or f(x)     -- results adjusted to 1
+
+ + + + +

2.5.9 - Function Definitions

+ +

+The syntax for function definition is + +

+	function ::= function funcbody
+	funcbody ::= `(´ [parlist] `)´ block end
+
+ +

+The following syntactic sugar simplifies function definitions: + +

+	stat ::= function funcname funcbody
+	stat ::= local function Name funcbody
+	funcname ::= Name {`.´ Name} [`:´ Name]
+

+The statement + +

+     function f () body end
+

+translates to + +

+     f = function () body end
+

+The statement + +

+     function t.a.b.c.f () body end
+

+translates to + +

+     t.a.b.c.f = function () body end
+

+The statement + +

+     local function f () body end
+

+translates to + +

+     local f; f = function () body end
+

+not to + +

+     local f = function () body end
+

+(This only makes a difference when the body of the function +contains references to f.) + + +

+A function definition is an executable expression, +whose value has type function. +When Lua pre-compiles a chunk, +all its function bodies are pre-compiled too. +Then, whenever Lua executes the function definition, +the function is instantiated (or closed). +This function instance (or closure) +is the final value of the expression. +Different instances of the same function +can refer to different external local variables +and can have different environment tables. + + +

+Parameters act as local variables that are +initialized with the argument values: + +

+

+When a function is called, +the list of arguments is adjusted to +the length of the list of parameters, +unless the function is a variadic or vararg function, +which is +indicated by three dots ('...') at the end of its parameter list. +A vararg function does not adjust its argument list; +instead, it collects all extra arguments and supplies them +to the function through a vararg expression, +which is also written as three dots. +The value of this expression is a list of all actual extra arguments, +similar to a function with multiple results. +If a vararg expression is used inside another expression +or in the middle of a list of expressions, +then its return list is adjusted to one element. +If the expression is used as the last element of a list of expressions, +then no adjustment is made +(unless that last expression is enclosed in parentheses). + + +

+As an example, consider the following definitions: + +

+     function f(a, b) end
+     function g(a, b, ...) end
+     function r() return 1,2,3 end
+

+Then, we have the following mapping from arguments to parameters and +to the vararg expression: + +

+     CALL            PARAMETERS
+     
+     f(3)             a=3, b=nil
+     f(3, 4)          a=3, b=4
+     f(3, 4, 5)       a=3, b=4
+     f(r(), 10)       a=1, b=10
+     f(r())           a=1, b=2
+     
+     g(3)             a=3, b=nil, ... -->  (nothing)
+     g(3, 4)          a=3, b=4,   ... -->  (nothing)
+     g(3, 4, 5, 8)    a=3, b=4,   ... -->  5  8
+     g(5, r())        a=5, b=1,   ... -->  2  3
+
+ +

+Results are returned using the return statement (see §2.4.4). +If control reaches the end of a function +without encountering a return statement, +then the function returns with no results. + + +

+The colon syntax +is used for defining methods, +that is, functions that have an implicit extra parameter self. +Thus, the statement + +

+     function t.a.b.c:f (params) body end
+

+is syntactic sugar for + +

+     t.a.b.c.f = function (self, params) body end
+
+ + + + + + +

2.6 - Visibility Rules

+ +

+ +Lua is a lexically scoped language. +The scope of variables begins at the first statement after +their declaration and lasts until the end of the innermost block that +includes the declaration. +Consider the following example: + +

+     x = 10                -- global variable
+     do                    -- new block
+       local x = x         -- new 'x', with value 10
+       print(x)            --> 10
+       x = x+1
+       do                  -- another block
+         local x = x+1     -- another 'x'
+         print(x)          --> 12
+       end
+       print(x)            --> 11
+     end
+     print(x)              --> 10  (the global one)
+
+ +

+Notice that, in a declaration like local x = x, +the new x being declared is not in scope yet, +and so the second x refers to the outside variable. + + +

+Because of the lexical scoping rules, +local variables can be freely accessed by functions +defined inside their scope. +A local variable used by an inner function is called +an upvalue, or external local variable, +inside the inner function. + + +

+Notice that each execution of a local statement +defines new local variables. +Consider the following example: + +

+     a = {}
+     local x = 20
+     for i=1,10 do
+       local y = 0
+       a[i] = function () y=y+1; return x+y end
+     end
+

+The loop creates ten closures +(that is, ten instances of the anonymous function). +Each of these closures uses a different y variable, +while all of them share the same x. + + + + + +

2.7 - Error Handling

+ +

+Because Lua is an embedded extension language, +all Lua actions start from C code in the host program +calling a function from the Lua library (see lua_pcall). +Whenever an error occurs during Lua compilation or execution, +control returns to C, +which can take appropriate measures +(such as printing an error message). + + +

+Lua code can explicitly generate an error by calling the +error function. +If you need to catch errors in Lua, +you can use the pcall function. + + + + + +

2.8 - Metatables

+ +

+Every value in Lua can have a metatable. +This metatable is an ordinary Lua table +that defines the behavior of the original value +under certain special operations. +You can change several aspects of the behavior +of operations over a value by setting specific fields in its metatable. +For instance, when a non-numeric value is the operand of an addition, +Lua checks for a function in the field "__add" in its metatable. +If it finds one, +Lua calls this function to perform the addition. + + +

+We call the keys in a metatable events +and the values metamethods. +In the previous example, the event is "add" +and the metamethod is the function that performs the addition. + + +

+You can query the metatable of any value +through the getmetatable function. + + +

+You can replace the metatable of tables +through the setmetatable +function. +You cannot change the metatable of other types from Lua +(except by using the debug library); +you must use the C API for that. + + +

+Tables and full userdata have individual metatables +(although multiple tables and userdata can share their metatables). +Values of all other types share one single metatable per type; +that is, there is one single metatable for all numbers, +one for all strings, etc. + + +

+A metatable controls how an object behaves in arithmetic operations, +order comparisons, concatenation, length operation, and indexing. +A metatable also can define a function to be called when a userdata +is garbage collected. +For each of these operations Lua associates a specific key +called an event. +When Lua performs one of these operations over a value, +it checks whether this value has a metatable with the corresponding event. +If so, the value associated with that key (the metamethod) +controls how Lua will perform the operation. + + +

+Metatables control the operations listed next. +Each operation is identified by its corresponding name. +The key for each operation is a string with its name prefixed by +two underscores, '__'; +for instance, the key for operation "add" is the +string "__add". +The semantics of these operations is better explained by a Lua function +describing how the interpreter executes the operation. + + +

+The code shown here in Lua is only illustrative; +the real behavior is hard coded in the interpreter +and it is much more efficient than this simulation. +All functions used in these descriptions +(rawget, tonumber, etc.) +are described in §5.1. +In particular, to retrieve the metamethod of a given object, +we use the expression + +

+     metatable(obj)[event]
+

+This should be read as + +

+     rawget(getmetatable(obj) or {}, event)
+

+ +That is, the access to a metamethod does not invoke other metamethods, +and the access to objects with no metatables does not fail +(it simply results in nil). + + + +

    + +
  • "add": +the + operation. + + + +

    +The function getbinhandler below defines how Lua chooses a handler +for a binary operation. +First, Lua tries the first operand. +If its type does not define a handler for the operation, +then Lua tries the second operand. + +

    +     function getbinhandler (op1, op2, event)
+       return metatable(op1)[event] or metatable(op2)[event]
+     end
+

    +By using this function, +the behavior of the op1 + op2 is + +

    +     function add_event (op1, op2)
+       local o1, o2 = tonumber(op1), tonumber(op2)
+       if o1 and o2 then  -- both operands are numeric?
+         return o1 + o2   -- '+' here is the primitive 'add'
+       else  -- at least one of the operands is not numeric
+         local h = getbinhandler(op1, op2, "__add")
+         if h then
+           -- call the handler with both operands
+           return (h(op1, op2))
+         else  -- no handler available: default behavior
+           error(···)

    • + +
  • "eq": +the == operation. + +The function getcomphandler defines how Lua chooses a metamethod +for comparison operators. +A metamethod only is selected when both objects +being compared have the same type +and the same metamethod for the selected operation. + +

    +The "eq" event is defined as follows: + +

    +     function eq_event (op1, op2)
+       if type(op1) ~= type(op2) then  -- different types?

2.9 - Environments

+ +

+Besides metatables, +objects of types thread, function, and userdata +have another table associated with them, +called their environment. +Like metatables, environments are regular tables and +multiple objects can share the same environment. + + +

+Threads are created sharing the environment of the creating thread. +Userdata and C functions are created sharing the environment +of the creating C function. +Non-nested Lua functions +(created by loadfile, loadstring or load) +are created sharing the environment of the creating thread. +Nested Lua functions are created sharing the environment of +the creating Lua function. + + +

+Environments associated with userdata have no meaning for Lua. +It is only a convenience feature for programmers to associate a table to +a userdata. + + +

+Environments associated with threads are called +global environments. +They are used as the default environment for threads and +non-nested Lua functions created by the thread +and can be directly accessed by C code (see §3.3). + + +

+The environment associated with a C function can be directly +accessed by C code (see §3.3). +It is used as the default environment for other C functions +and userdata created by the function. + + +

+Environments associated with Lua functions are used to resolve +all accesses to global variables within the function (see §2.3). +They are used as the default environment for nested Lua functions +created by the function. + + +

+You can change the environment of a Lua function or the +running thread by calling setfenv. +You can get the environment of a Lua function or the running thread +by calling getfenv. +To manipulate the environment of other objects +(userdata, C functions, other threads) you must +use the C API. + + + + + +

2.10 - Garbage Collection

+ +

+Lua performs automatic memory management. +This means that +you have to worry neither about allocating memory for new objects +nor about freeing it when the objects are no longer needed. +Lua manages memory automatically by running +a garbage collector from time to time +to collect all dead objects +(that is, objects that are no longer accessible from Lua). +All memory used by Lua is subject to automatic management: +tables, userdata, functions, threads, strings, etc. + + +

+Lua implements an incremental mark-and-sweep collector. +It uses two numbers to control its garbage-collection cycles: +the garbage-collector pause and +the garbage-collector step multiplier. +Both use percentage points as units +(so that a value of 100 means an internal value of 1). + + +

+The garbage-collector pause +controls how long the collector waits before starting a new cycle. +Larger values make the collector less aggressive. +Values smaller than 100 mean the collector will not wait to +start a new cycle. +A value of 200 means that the collector waits for the total memory in use +to double before starting a new cycle. + + +

+The step multiplier +controls the relative speed of the collector relative to +memory allocation. +Larger values make the collector more aggressive but also increase +the size of each incremental step. +Values smaller than 100 make the collector too slow and +can result in the collector never finishing a cycle. +The default, 200, means that the collector runs at "twice" +the speed of memory allocation. + + +

+You can change these numbers by calling lua_gc in C +or collectgarbage in Lua. +With these functions you can also control +the collector directly (e.g., stop and restart it). + + + +

2.10.1 - Garbage-Collection Metamethods

+ +

+Using the C API, +you can set garbage-collector metamethods for userdata (see §2.8). +These metamethods are also called finalizers. +Finalizers allow you to coordinate Lua's garbage collection +with external resource management +(such as closing files, network or database connections, +or freeing your own memory). + + +

+Garbage userdata with a field __gc in their metatables are not +collected immediately by the garbage collector. +Instead, Lua puts them in a list. +After the collection, +Lua does the equivalent of the following function +for each userdata in that list: + +

+     function gc_event (udata)
+       local h = metatable(udata).__gc
+       if h then
+         h(udata)
+       end
+     end
+
+ +

+At the end of each garbage-collection cycle, +the finalizers for userdata are called in reverse +order of their creation, +among those collected in that cycle. +That is, the first finalizer to be called is the one associated +with the userdata created last in the program. +The userdata itself is freed only in the next garbage-collection cycle. + + + + + +

2.10.2 - Weak Tables

+ +

+A weak table is a table whose elements are +weak references. +A weak reference is ignored by the garbage collector. +In other words, +if the only references to an object are weak references, +then the garbage collector will collect this object. + + +

+A weak table can have weak keys, weak values, or both. +A table with weak keys allows the collection of its keys, +but prevents the collection of its values. +A table with both weak keys and weak values allows the collection of +both keys and values. +In any case, if either the key or the value is collected, +the whole pair is removed from the table. +The weakness of a table is controlled by the +__mode field of its metatable. +If the __mode field is a string containing the character 'k', +the keys in the table are weak. +If __mode contains 'v', +the values in the table are weak. + + +

+After you use a table as a metatable, +you should not change the value of its __mode field. +Otherwise, the weak behavior of the tables controlled by this +metatable is undefined. + + + + + + + +

2.11 - Coroutines

+ +

+Lua supports coroutines, +also called collaborative multithreading. +A coroutine in Lua represents an independent thread of execution. +Unlike threads in multithread systems, however, +a coroutine only suspends its execution by explicitly calling +a yield function. + + +

+You create a coroutine with a call to coroutine.create. +Its sole argument is a function +that is the main function of the coroutine. +The create function only creates a new coroutine and +returns a handle to it (an object of type thread); +it does not start the coroutine execution. + + +

+When you first call coroutine.resume, +passing as its first argument +a thread returned by coroutine.create, +the coroutine starts its execution, +at the first line of its main function. +Extra arguments passed to coroutine.resume are passed on +to the coroutine main function. +After the coroutine starts running, +it runs until it terminates or yields. + + +

+A coroutine can terminate its execution in two ways: +normally, when its main function returns +(explicitly or implicitly, after the last instruction); +and abnormally, if there is an unprotected error. +In the first case, coroutine.resume returns true, +plus any values returned by the coroutine main function. +In case of errors, coroutine.resume returns false +plus an error message. + + +

+A coroutine yields by calling coroutine.yield. +When a coroutine yields, +the corresponding coroutine.resume returns immediately, +even if the yield happens inside nested function calls +(that is, not in the main function, +but in a function directly or indirectly called by the main function). +In the case of a yield, coroutine.resume also returns true, +plus any values passed to coroutine.yield. +The next time you resume the same coroutine, +it continues its execution from the point where it yielded, +with the call to coroutine.yield returning any extra +arguments passed to coroutine.resume. + + +

+Like coroutine.create, +the coroutine.wrap function also creates a coroutine, +but instead of returning the coroutine itself, +it returns a function that, when called, resumes the coroutine. +Any arguments passed to this function +go as extra arguments to coroutine.resume. +coroutine.wrap returns all the values returned by coroutine.resume, +except the first one (the boolean error code). +Unlike coroutine.resume, +coroutine.wrap does not catch errors; +any error is propagated to the caller. + + +

+As an example, +consider the following code: + +

+     function foo (a)
+       print("foo", a)
+       return coroutine.yield(2*a)
+     end
+     
+     co = coroutine.create(function (a,b)
+           print("co-body", a, b)
+           local r = foo(a+1)
+           print("co-body", r)
+           local r, s = coroutine.yield(a+b, a-b)
+           print("co-body", r, s)
+           return b, "end"
+     end)
+            
+     print("main", coroutine.resume(co, 1, 10))
+     print("main", coroutine.resume(co, "r"))
+     print("main", coroutine.resume(co, "x", "y"))
+     print("main", coroutine.resume(co, "x", "y"))
+

+When you run it, it produces the following output: + +

+     co-body 1       10
+     foo     2
+     
+     main    true    4
+     co-body r

+     co-body x       y
+     main    true    10      end
+     main    false   cannot resume dead coroutine

3 - The Application Program Interface

+ +

+ +This section describes the C API for Lua, that is, +the set of C functions available to the host program to communicate +with Lua. +All API functions and related types and constants +are declared in the header file lua.h. + + +

+Even when we use the term "function", +any facility in the API may be provided as a macro instead. +All such macros use each of their arguments exactly once +(except for the first argument, which is always a Lua state), +and so do not generate any hidden side-effects. + + +

+As in most C libraries, +the Lua API functions do not check their arguments for validity or consistency. +However, you can change this behavior by compiling Lua +with a proper definition for the macro luai_apicheck, +in file luaconf.h. + + + +

3.1 - The Stack

+ +

+Lua uses a virtual stack to pass values to and from C. +Each element in this stack represents a Lua value +(nil, number, string, etc.). + + +

+Whenever Lua calls C, the called function gets a new stack, +which is independent of previous stacks and of stacks of +C functions that are still active. +This stack initially contains any arguments to the C function +and it is where the C function pushes its results +to be returned to the caller (see lua_CFunction). + + +

+For convenience, +most query operations in the API do not follow a strict stack discipline. +Instead, they can refer to any element in the stack +by using an index: +A positive index represents an absolute stack position +(starting at 1); +a negative index represents an offset relative to the top of the stack. +More specifically, if the stack has n elements, +then index 1 represents the first element +(that is, the element that was pushed onto the stack first) +and +index n represents the last element; +index -1 also represents the last element +(that is, the element at the top) +and index -n represents the first element. +We say that an index is valid +if it lies between 1 and the stack top +(that is, if 1 ≤ abs(index) ≤ top). + + + + + + +

3.2 - Stack Size

+ +

+When you interact with Lua API, +you are responsible for ensuring consistency. +In particular, +you are responsible for controlling stack overflow. +You can use the function lua_checkstack +to grow the stack size. + + +

+Whenever Lua calls C, +it ensures that at least LUA_MINSTACK stack positions are available. +LUA_MINSTACK is defined as 20, +so that usually you do not have to worry about stack space +unless your code has loops pushing elements onto the stack. + + +

+Most query functions accept as indices any value inside the +available stack space, that is, indices up to the maximum stack size +you have set through lua_checkstack. +Such indices are called acceptable indices. +More formally, we define an acceptable index +as follows: + +

+     (index < 0 && abs(index) <= top) ||
+     (index > 0 && index <= stackspace)
+

+Note that 0 is never an acceptable index. + + + + + +

3.3 - Pseudo-Indices

+ +

+Unless otherwise noted, +any function that accepts valid indices can also be called with +pseudo-indices, +which represent some Lua values that are accessible to C code +but which are not in the stack. +Pseudo-indices are used to access the thread environment, +the function environment, +the registry, +and the upvalues of a C function (see §3.4). + + +

+The thread environment (where global variables live) is +always at pseudo-index LUA_GLOBALSINDEX. +The environment of the running C function is always +at pseudo-index LUA_ENVIRONINDEX. + + +

+To access and change the value of global variables, +you can use regular table operations over an environment table. +For instance, to access the value of a global variable, do + +

+     lua_getfield(L, LUA_GLOBALSINDEX, varname);
+
+ + + + +

3.4 - C Closures

+ +

+When a C function is created, +it is possible to associate some values with it, +thus creating a C closure; +these values are called upvalues and are +accessible to the function whenever it is called +(see lua_pushcclosure). + + +

+Whenever a C function is called, +its upvalues are located at specific pseudo-indices. +These pseudo-indices are produced by the macro +lua_upvalueindex. +The first value associated with a function is at position +lua_upvalueindex(1), and so on. +Any access to lua_upvalueindex(n), +where n is greater than the number of upvalues of the +current function (but not greater than 256), +produces an acceptable (but invalid) index. + + + + + +

3.5 - Registry

+ +

+Lua provides a registry, +a pre-defined table that can be used by any C code to +store whatever Lua value it needs to store. +This table is always located at pseudo-index +LUA_REGISTRYINDEX. +Any C library can store data into this table, +but it should take care to choose keys different from those used +by other libraries, to avoid collisions. +Typically, you should use as key a string containing your library name +or a light userdata with the address of a C object in your code. + + +

+The integer keys in the registry are used by the reference mechanism, +implemented by the auxiliary library, +and therefore should not be used for other purposes. + + + + + +

3.6 - Error Handling in C

+ +

+Internally, Lua uses the C longjmp facility to handle errors. +(You can also choose to use exceptions if you use C++; +see file luaconf.h.) +When Lua faces any error +(such as memory allocation errors, type errors, syntax errors, +and runtime errors) +it raises an error; +that is, it does a long jump. +A protected environment uses setjmp +to set a recover point; +any error jumps to the most recent active recover point. + + +

+Most functions in the API can throw an error, +for instance due to a memory allocation error. +The documentation for each function indicates whether +it can throw errors. + + +

+Inside a C function you can throw an error by calling lua_error. + + + + + +

3.7 - Functions and Types

+ +

+Here we list all functions and types from the C API in +alphabetical order. +Each function has an indicator like this: +[-o, +p, x] + + +

+The first field, o, +is how many elements the function pops from the stack. +The second field, p, +is how many elements the function pushes onto the stack. +(Any function always pushes its results after popping its arguments.) +A field in the form x|y means the function can push (or pop) +x or y elements, +depending on the situation; +an interrogation mark '?' means that +we cannot know how many elements the function pops/pushes +by looking only at its arguments +(e.g., they may depend on what is on the stack). +The third field, x, +tells whether the function may throw errors: +'-' means the function never throws any error; +'m' means the function may throw an error +only due to not enough memory; +'e' means the function may throw other kinds of errors; +'v' means the function may throw an error on purpose. + + + +

lua_Alloc

+
typedef void * (*lua_Alloc) (void *ud,
+                             void *ptr,
+                             size_t osize,
+                             size_t nsize);
+ +

+The type of the memory-allocation function used by Lua states. +The allocator function must provide a +functionality similar to realloc, +but not exactly the same. +Its arguments are +ud, an opaque pointer passed to lua_newstate; +ptr, a pointer to the block being allocated/reallocated/freed; +osize, the original size of the block; +nsize, the new size of the block. +ptr is NULL if and only if osize is zero. +When nsize is zero, the allocator must return NULL; +if osize is not zero, +it should free the block pointed to by ptr. +When nsize is not zero, the allocator returns NULL +if and only if it cannot fill the request. +When nsize is not zero and osize is zero, +the allocator should behave like malloc. +When nsize and osize are not zero, +the allocator behaves like realloc. +Lua assumes that the allocator never fails when +osize >= nsize. + + +

+Here is a simple implementation for the allocator function. +It is used in the auxiliary library by luaL_newstate. + +

+     static void *l_alloc (void *ud, void *ptr, size_t osize,
+                                                size_t nsize) {
+       (void)ud;  (void)osize;  /* not used */
+       if (nsize == 0) {
+         free(ptr);
+         return NULL;
+       }
+       else
+         return realloc(ptr, nsize);
+     }
+

+This code assumes +that free(NULL) has no effect and that +realloc(NULL, size) is equivalent to malloc(size). +ANSI C ensures both behaviors. + + + + + +

lua_atpanic

+[-0, +0, -] +

lua_CFunction lua_atpanic (lua_State *L, lua_CFunction panicf);
+ +

+Sets a new panic function and returns the old one. + + +

+If an error happens outside any protected environment, +Lua calls a panic function +and then calls exit(EXIT_FAILURE), +thus exiting the host application. +Your panic function can avoid this exit by +never returning (e.g., doing a long jump). + + +

+The panic function can access the error message at the top of the stack. + + + + + +

lua_call

+[-(nargs + 1), +nresults, e] +

void lua_call (lua_State *L, int nargs, int nresults);
+ +

+Calls a function. + + +

+To call a function you must use the following protocol: +first, the function to be called is pushed onto the stack; +then, the arguments to the function are pushed +in direct order; +that is, the first argument is pushed first. +Finally you call lua_call; +nargs is the number of arguments that you pushed onto the stack. +All arguments and the function value are popped from the stack +when the function is called. +The function results are pushed onto the stack when the function returns. +The number of results is adjusted to nresults, +unless nresults is LUA_MULTRET. +In this case, all results from the function are pushed. +Lua takes care that the returned values fit into the stack space. +The function results are pushed onto the stack in direct order +(the first result is pushed first), +so that after the call the last result is on the top of the stack. + + +

+Any error inside the called function is propagated upwards +(with a longjmp). + + +

+The following example shows how the host program can do the +equivalent to this Lua code: + +

+     a = f("how", t.x, 14)
+

+Here it is in C: + +

+     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
+     lua_pushstring(L, "how");                        /* 1st argument */
+     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
+     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
+     lua_remove(L, -2);                  /* remove 't' from the stack */
+     lua_pushinteger(L, 14);                          /* 3rd argument */
+     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
+     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */
+

+Note that the code above is "balanced": +at its end, the stack is back to its original configuration. +This is considered good programming practice. + + + + + +

lua_CFunction

+
typedef int (*lua_CFunction) (lua_State *L);
+ +

+Type for C functions. + + +

+In order to communicate properly with Lua, +a C function must use the following protocol, +which defines the way parameters and results are passed: +a C function receives its arguments from Lua in its stack +in direct order (the first argument is pushed first). +So, when the function starts, +lua_gettop(L) returns the number of arguments received by the function. +The first argument (if any) is at index 1 +and its last argument is at index lua_gettop(L). +To return values to Lua, a C function just pushes them onto the stack, +in direct order (the first result is pushed first), +and returns the number of results. +Any other value in the stack below the results will be properly +discarded by Lua. +Like a Lua function, a C function called by Lua can also return +many results. + + +

+As an example, the following function receives a variable number +of numerical arguments and returns their average and sum: + +

+     static int foo (lua_State *L) {
+       int n = lua_gettop(L);    /* number of arguments */
+       lua_Number sum = 0;
+       int i;
+       for (i = 1; i <= n; i++) {
+         if (!lua_isnumber(L, i)) {
+           lua_pushstring(L, "incorrect argument");
+           lua_error(L);
+         }
+         sum += lua_tonumber(L, i);
+       }
+       lua_pushnumber(L, sum/n);        /* first result */
+       lua_pushnumber(L, sum);         /* second result */
+       return 2;                   /* number of results */
+     }
+
+ + + + +

lua_checkstack

+[-0, +0, m] +

int lua_checkstack (lua_State *L, int extra);
+ +

+Ensures that there are at least extra free stack slots in the stack. +It returns false if it cannot grow the stack to that size. +This function never shrinks the stack; +if the stack is already larger than the new size, +it is left unchanged. + + + + + +

lua_close

+[-0, +0, -] +

void lua_close (lua_State *L);
+ +

+Destroys all objects in the given Lua state +(calling the corresponding garbage-collection metamethods, if any) +and frees all dynamic memory used by this state. +On several platforms, you may not need to call this function, +because all resources are naturally released when the host program ends. +On the other hand, long-running programs, +such as a daemon or a web server, +might need to release states as soon as they are not needed, +to avoid growing too large. + + + + + +

lua_concat

+[-n, +1, e] +

void lua_concat (lua_State *L, int n);
+ +

+Concatenates the n values at the top of the stack, +pops them, and leaves the result at the top. +If n is 1, the result is the single value on the stack +(that is, the function does nothing); +if n is 0, the result is the empty string. +Concatenation is performed following the usual semantics of Lua +(see §2.5.4). + + + + + +

lua_cpcall

+[-0, +(0|1), -] +

int lua_cpcall (lua_State *L, lua_CFunction func, void *ud);
+ +

+Calls the C function func in protected mode. +func starts with only one element in its stack, +a light userdata containing ud. +In case of errors, +lua_cpcall returns the same error codes as lua_pcall, +plus the error object on the top of the stack; +otherwise, it returns zero, and does not change the stack. +All values returned by func are discarded. + + + + + +

lua_createtable

+[-0, +1, m] +

void lua_createtable (lua_State *L, int narr, int nrec);
+ +

+Creates a new empty table and pushes it onto the stack. +The new table has space pre-allocated +for narr array elements and nrec non-array elements. +This pre-allocation is useful when you know exactly how many elements +the table will have. +Otherwise you can use the function lua_newtable. + + + + + +

lua_dump

+[-0, +0, m] +

int lua_dump (lua_State *L, lua_Writer writer, void *data);
+ +

+Dumps a function as a binary chunk. +Receives a Lua function on the top of the stack +and produces a binary chunk that, +if loaded again, +results in a function equivalent to the one dumped. +As it produces parts of the chunk, +lua_dump calls function writer (see lua_Writer) +with the given data +to write them. + + +

+The value returned is the error code returned by the last +call to the writer; +0 means no errors. + + +

+This function does not pop the Lua function from the stack. + + + + + +

lua_equal

+[-0, +0, e] +

int lua_equal (lua_State *L, int index1, int index2);
+ +

+Returns 1 if the two values in acceptable indices index1 and +index2 are equal, +following the semantics of the Lua == operator +(that is, may call metamethods). +Otherwise returns 0. +Also returns 0 if any of the indices is non valid. + + + + + +

lua_error

+[-1, +0, v] +

int lua_error (lua_State *L);
+ +

+Generates a Lua error. +The error message (which can actually be a Lua value of any type) +must be on the stack top. +This function does a long jump, +and therefore never returns. +(see luaL_error). + + + + + +

lua_gc

+[-0, +0, e] +

int lua_gc (lua_State *L, int what, int data);
+ +

+Controls the garbage collector. + + +

+This function performs several tasks, +according to the value of the parameter what: + +

    + +
  • LUA_GCSTOP: +stops the garbage collector. +
    • + +
  • LUA_GCRESTART: +restarts the garbage collector. +
    • + +
  • LUA_GCCOLLECT: +performs a full garbage-collection cycle. +
    • + +
  • LUA_GCCOUNT: +returns the current amount of memory (in Kbytes) in use by Lua. +
    • + +
  • LUA_GCCOUNTB: +returns the remainder of dividing the current amount of bytes of +memory in use by Lua by 1024. +
    • + +
  • LUA_GCSTEP: +performs an incremental step of garbage collection. +The step "size" is controlled by data +(larger values mean more steps) in a non-specified way. +If you want to control the step size +you must experimentally tune the value of data. +The function returns 1 if the step finished a +garbage-collection cycle. +
    • + +
  • LUA_GCSETPAUSE: +sets data as the new value +for the pause of the collector (see §2.10). +The function returns the previous value of the pause. +
    • + +
  • LUA_GCSETSTEPMUL: +sets data as the new value for the step multiplier of +the collector (see §2.10). +The function returns the previous value of the step multiplier. +
    • + +
+ + + + +

lua_getallocf

+[-0, +0, -] +

lua_Alloc lua_getallocf (lua_State *L, void **ud);
+ +

+Returns the memory-allocation function of a given state. +If ud is not NULL, Lua stores in *ud the +opaque pointer passed to lua_newstate. + + + + + +

lua_getfenv

+[-0, +1, -] +

void lua_getfenv (lua_State *L, int index);
+ +

+Pushes onto the stack the environment table of +the value at the given index. + + + + + +

lua_getfield

+[-0, +1, e] +

void lua_getfield (lua_State *L, int index, const char *k);
+ +

+Pushes onto the stack the value t[k], +where t is the value at the given valid index. +As in Lua, this function may trigger a metamethod +for the "index" event (see §2.8). + + + + + +

lua_getglobal

+[-0, +1, e] +

void lua_getglobal (lua_State *L, const char *name);
+ +

+Pushes onto the stack the value of the global name. +It is defined as a macro: + +

+     #define lua_getglobal(L,s)  lua_getfield(L, LUA_GLOBALSINDEX, s)
+
+ + + + +

lua_getmetatable

+[-0, +(0|1), -] +

int lua_getmetatable (lua_State *L, int index);
+ +

+Pushes onto the stack the metatable of the value at the given +acceptable index. +If the index is not valid, +or if the value does not have a metatable, +the function returns 0 and pushes nothing on the stack. + + + + + +

lua_gettable

+[-1, +1, e] +

void lua_gettable (lua_State *L, int index);
+ +

+Pushes onto the stack the value t[k], +where t is the value at the given valid index +and k is the value at the top of the stack. + + +

+This function pops the key from the stack +(putting the resulting value in its place). +As in Lua, this function may trigger a metamethod +for the "index" event (see §2.8). + + + + + +

lua_gettop

+[-0, +0, -] +

int lua_gettop (lua_State *L);
+ +

+Returns the index of the top element in the stack. +Because indices start at 1, +this result is equal to the number of elements in the stack +(and so 0 means an empty stack). + + + + + +

lua_insert

+[-1, +1, -] +

void lua_insert (lua_State *L, int index);
+ +

+Moves the top element into the given valid index, +shifting up the elements above this index to open space. +Cannot be called with a pseudo-index, +because a pseudo-index is not an actual stack position. + + + + + +

lua_Integer

+
typedef ptrdiff_t lua_Integer;
+ +

+The type used by the Lua API to represent integral values. + + +

+By default it is a ptrdiff_t, +which is usually the largest signed integral type the machine handles +"comfortably". + + + + + +

lua_isboolean

+[-0, +0, -] +

int lua_isboolean (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index has type boolean, +and 0 otherwise. + + + + + +

lua_iscfunction

+[-0, +0, -] +

int lua_iscfunction (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a C function, +and 0 otherwise. + + + + + +

lua_isfunction

+[-0, +0, -] +

int lua_isfunction (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a function +(either C or Lua), and 0 otherwise. + + + + + +

lua_islightuserdata

+[-0, +0, -] +

int lua_islightuserdata (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a light userdata, +and 0 otherwise. + + + + + +

lua_isnil

+[-0, +0, -] +

int lua_isnil (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is nil, +and 0 otherwise. + + + + + +

lua_isnone

+[-0, +0, -] +

int lua_isnone (lua_State *L, int index);
+ +

+Returns 1 if the given acceptable index is not valid +(that is, it refers to an element outside the current stack), +and 0 otherwise. + + + + + +

lua_isnoneornil

+[-0, +0, -] +

int lua_isnoneornil (lua_State *L, int index);
+ +

+Returns 1 if the given acceptable index is not valid +(that is, it refers to an element outside the current stack) +or if the value at this index is nil, +and 0 otherwise. + + + + + +

lua_isnumber

+[-0, +0, -] +

int lua_isnumber (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a number +or a string convertible to a number, +and 0 otherwise. + + + + + +

lua_isstring

+[-0, +0, -] +

int lua_isstring (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a string +or a number (which is always convertible to a string), +and 0 otherwise. + + + + + +

lua_istable

+[-0, +0, -] +

int lua_istable (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a table, +and 0 otherwise. + + + + + +

lua_isthread

+[-0, +0, -] +

int lua_isthread (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a thread, +and 0 otherwise. + + + + + +

lua_isuserdata

+[-0, +0, -] +

int lua_isuserdata (lua_State *L, int index);
+ +

+Returns 1 if the value at the given acceptable index is a userdata +(either full or light), and 0 otherwise. + + + + + +

lua_lessthan

+[-0, +0, e] +

int lua_lessthan (lua_State *L, int index1, int index2);
+ +

+Returns 1 if the value at acceptable index index1 is smaller +than the value at acceptable index index2, +following the semantics of the Lua < operator +(that is, may call metamethods). +Otherwise returns 0. +Also returns 0 if any of the indices is non valid. + + + + + +

lua_load

+[-0, +1, -] +

int lua_load (lua_State *L,
+              lua_Reader reader,
+              void *data,
+              const char *chunkname);
+ +

+Loads a Lua chunk. +If there are no errors, +lua_load pushes the compiled chunk as a Lua +function on top of the stack. +Otherwise, it pushes an error message. +The return values of lua_load are: + +

    + +
  • 0: no errors;
    • + +
  • LUA_ERRSYNTAX: +syntax error during pre-compilation;
    • + +
  • LUA_ERRMEM: +memory allocation error.
    • + +
+ +

+This function only loads a chunk; +it does not run it. + + +

+lua_load automatically detects whether the chunk is text or binary, +and loads it accordingly (see program luac). + + +

+The lua_load function uses a user-supplied reader function +to read the chunk (see lua_Reader). +The data argument is an opaque value passed to the reader function. + + +

+The chunkname argument gives a name to the chunk, +which is used for error messages and in debug information (see §3.8). + + + + + +

lua_newstate

+[-0, +0, -] +

lua_State *lua_newstate (lua_Alloc f, void *ud);
+ +

+Creates a new, independent state. +Returns NULL if cannot create the state +(due to lack of memory). +The argument f is the allocator function; +Lua does all memory allocation for this state through this function. +The second argument, ud, is an opaque pointer that Lua +simply passes to the allocator in every call. + + + + + +

lua_newtable

+[-0, +1, m] +

void lua_newtable (lua_State *L);
+ +

+Creates a new empty table and pushes it onto the stack. +It is equivalent to lua_createtable(L, 0, 0). + + + + + +

lua_newthread

+[-0, +1, m] +

lua_State *lua_newthread (lua_State *L);
+ +

+Creates a new thread, pushes it on the stack, +and returns a pointer to a lua_State that represents this new thread. +The new state returned by this function shares with the original state +all global objects (such as tables), +but has an independent execution stack. + + +

+There is no explicit function to close or to destroy a thread. +Threads are subject to garbage collection, +like any Lua object. + + + + + +

lua_newuserdata

+[-0, +1, m] +

void *lua_newuserdata (lua_State *L, size_t size);
+ +

+This function allocates a new block of memory with the given size, +pushes onto the stack a new full userdata with the block address, +and returns this address. + + +

+Userdata represent C values in Lua. +A full userdata represents a block of memory. +It is an object (like a table): +you must create it, it can have its own metatable, +and you can detect when it is being collected. +A full userdata is only equal to itself (under raw equality). + + +

+When Lua collects a full userdata with a gc metamethod, +Lua calls the metamethod and marks the userdata as finalized. +When this userdata is collected again then +Lua frees its corresponding memory. + + + + + +

lua_next

+[-1, +(2|0), e] +

int lua_next (lua_State *L, int index);
+ +

+Pops a key from the stack, +and pushes a key-value pair from the table at the given index +(the "next" pair after the given key). +If there are no more elements in the table, +then lua_next returns 0 (and pushes nothing). + + +

+A typical traversal looks like this: + +

+     /* table is in the stack at index 't' */
+     lua_pushnil(L);  /* first key */
+     while (lua_next(L, t) != 0) {
+       /* uses 'key' (at index -2) and 'value' (at index -1) */
+       printf("%s - %s\n",
+              lua_typename(L, lua_type(L, -2)),
+              lua_typename(L, lua_type(L, -1)));
+       /* removes 'value'; keeps 'key' for next iteration */
+       lua_pop(L, 1);
+     }
+
+ +

+While traversing a table, +do not call lua_tolstring directly on a key, +unless you know that the key is actually a string. +Recall that lua_tolstring changes +the value at the given index; +this confuses the next call to lua_next. + + + + + +

lua_Number

+
typedef double lua_Number;
+ +

+The type of numbers in Lua. +By default, it is double, but that can be changed in luaconf.h. + + +

+Through the configuration file you can change +Lua to operate with another type for numbers (e.g., float or long). + + + + + +

lua_objlen

+[-0, +0, -] +

size_t lua_objlen (lua_State *L, int index);
+ +

+Returns the "length" of the value at the given acceptable index: +for strings, this is the string length; +for tables, this is the result of the length operator ('#'); +for userdata, this is the size of the block of memory allocated +for the userdata; +for other values, it is 0. + + + + + +

lua_pcall

+[-(nargs + 1), +(nresults|1), -] +

int lua_pcall (lua_State *L, int nargs, int nresults, int errfunc);
+ +

+Calls a function in protected mode. + + +

+Both nargs and nresults have the same meaning as +in lua_call. +If there are no errors during the call, +lua_pcall behaves exactly like lua_call. +However, if there is any error, +lua_pcall catches it, +pushes a single value on the stack (the error message), +and returns an error code. +Like lua_call, +lua_pcall always removes the function +and its arguments from the stack. + + +

+If errfunc is 0, +then the error message returned on the stack +is exactly the original error message. +Otherwise, errfunc is the stack index of an +error handler function. +(In the current implementation, this index cannot be a pseudo-index.) +In case of runtime errors, +this function will be called with the error message +and its return value will be the message returned on the stack by lua_pcall. + + +

+Typically, the error handler function is used to add more debug +information to the error message, such as a stack traceback. +Such information cannot be gathered after the return of lua_pcall, +since by then the stack has unwound. + + +

+The lua_pcall function returns 0 in case of success +or one of the following error codes +(defined in lua.h): + +

    + +
  • LUA_ERRRUN: +a runtime error. +
    • + +
  • LUA_ERRMEM: +memory allocation error. +For such errors, Lua does not call the error handler function. +
    • + +
  • LUA_ERRERR: +error while running the error handler function. +
    • + +
+ + + + +

lua_pop

+[-n, +0, -] +

void lua_pop (lua_State *L, int n);
+ +

+Pops n elements from the stack. + + + + + +

lua_pushboolean

+[-0, +1, -] +

void lua_pushboolean (lua_State *L, int b);
+ +

+Pushes a boolean value with value b onto the stack. + + + + + +

lua_pushcclosure

+[-n, +1, m] +

void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);
+ +

+Pushes a new C closure onto the stack. + + +

+When a C function is created, +it is possible to associate some values with it, +thus creating a C closure (see §3.4); +these values are then accessible to the function whenever it is called. +To associate values with a C function, +first these values should be pushed onto the stack +(when there are multiple values, the first value is pushed first). +Then lua_pushcclosure +is called to create and push the C function onto the stack, +with the argument n telling how many values should be +associated with the function. +lua_pushcclosure also pops these values from the stack. + + +

+The maximum value for n is 255. + + + + + +

lua_pushcfunction

+[-0, +1, m] +

void lua_pushcfunction (lua_State *L, lua_CFunction f);
+ +

+Pushes a C function onto the stack. +This function receives a pointer to a C function +and pushes onto the stack a Lua value of type function that, +when called, invokes the corresponding C function. + + +

+Any function to be registered in Lua must +follow the correct protocol to receive its parameters +and return its results (see lua_CFunction). + + +

+lua_pushcfunction is defined as a macro: + +

+     #define lua_pushcfunction(L,f)  lua_pushcclosure(L,f,0)
+
+ + + + +

lua_pushfstring

+[-0, +1, m] +

const char *lua_pushfstring (lua_State *L, const char *fmt, ...);
+ +

+Pushes onto the stack a formatted string +and returns a pointer to this string. +It is similar to the C function sprintf, +but has some important differences: + +

    + +
  • +You do not have to allocate space for the result: +the result is a Lua string and Lua takes care of memory allocation +(and deallocation, through garbage collection). +
    • + +
  • +The conversion specifiers are quite restricted. +There are no flags, widths, or precisions. +The conversion specifiers can only be +'%%' (inserts a '%' in the string), +'%s' (inserts a zero-terminated string, with no size restrictions), +'%f' (inserts a lua_Number), +'%p' (inserts a pointer as a hexadecimal numeral), +'%d' (inserts an int), and +'%c' (inserts an int as a character). +
    • + +
+ + + + +

lua_pushinteger

+[-0, +1, -] +

void lua_pushinteger (lua_State *L, lua_Integer n);
+ +

+Pushes a number with value n onto the stack. + + + + + +

lua_pushlightuserdata

+[-0, +1, -] +

void lua_pushlightuserdata (lua_State *L, void *p);
+ +

+Pushes a light userdata onto the stack. + + +

+Userdata represent C values in Lua. +A light userdata represents a pointer. +It is a value (like a number): +you do not create it, it has no individual metatable, +and it is not collected (as it was never created). +A light userdata is equal to "any" +light userdata with the same C address. + + + + + +

lua_pushliteral

+[-0, +1, m] +

void lua_pushliteral (lua_State *L, const char *s);
+ +

+This macro is equivalent to lua_pushlstring, +but can be used only when s is a literal string. +In these cases, it automatically provides the string length. + + + + + +

lua_pushlstring

+[-0, +1, m] +

void lua_pushlstring (lua_State *L, const char *s, size_t len);
+ +

+Pushes the string pointed to by s with size len +onto the stack. +Lua makes (or reuses) an internal copy of the given string, +so the memory at s can be freed or reused immediately after +the function returns. +The string can contain embedded zeros. + + + + + +

lua_pushnil

+[-0, +1, -] +

void lua_pushnil (lua_State *L);
+ +

+Pushes a nil value onto the stack. + + + + + +

lua_pushnumber

+[-0, +1, -] +

void lua_pushnumber (lua_State *L, lua_Number n);
+ +

+Pushes a number with value n onto the stack. + + + + + +

lua_pushstring

+[-0, +1, m] +

void lua_pushstring (lua_State *L, const char *s);
+ +

+Pushes the zero-terminated string pointed to by s +onto the stack. +Lua makes (or reuses) an internal copy of the given string, +so the memory at s can be freed or reused immediately after +the function returns. +The string cannot contain embedded zeros; +it is assumed to end at the first zero. + + + + + +

lua_pushthread

+[-0, +1, -] +

int lua_pushthread (lua_State *L);
+ +

+Pushes the thread represented by L onto the stack. +Returns 1 if this thread is the main thread of its state. + + + + + +

lua_pushvalue

+[-0, +1, -] +

void lua_pushvalue (lua_State *L, int index);
+ +

+Pushes a copy of the element at the given valid index +onto the stack. + + + + + +

lua_pushvfstring

+[-0, +1, m] +

const char *lua_pushvfstring (lua_State *L,
+                              const char *fmt,
+                              va_list argp);
+ +

+Equivalent to lua_pushfstring, except that it receives a va_list +instead of a variable number of arguments. + + + + + +

lua_rawequal

+[-0, +0, -] +

int lua_rawequal (lua_State *L, int index1, int index2);
+ +

+Returns 1 if the two values in acceptable indices index1 and +index2 are primitively equal +(that is, without calling metamethods). +Otherwise returns 0. +Also returns 0 if any of the indices are non valid. + + + + + +

lua_rawget

+[-1, +1, -] +

void lua_rawget (lua_State *L, int index);
+ +

+Similar to lua_gettable, but does a raw access +(i.e., without metamethods). + + + + + +

lua_rawgeti

+[-0, +1, -] +

void lua_rawgeti (lua_State *L, int index, int n);
+ +

+Pushes onto the stack the value t[n], +where t is the value at the given valid index. +The access is raw; +that is, it does not invoke metamethods. + + + + + +

lua_rawset

+[-2, +0, m] +

void lua_rawset (lua_State *L, int index);
+ +

+Similar to lua_settable, but does a raw assignment +(i.e., without metamethods). + + + + + +

lua_rawseti

+[-1, +0, m] +

void lua_rawseti (lua_State *L, int index, int n);
+ +

+Does the equivalent of t[n] = v, +where t is the value at the given valid index +and v is the value at the top of the stack. + + +

+This function pops the value from the stack. +The assignment is raw; +that is, it does not invoke metamethods. + + + + + +

lua_Reader

+
typedef const char * (*lua_Reader) (lua_State *L,
+                                    void *data,
+                                    size_t *size);
+ +

+The reader function used by lua_load. +Every time it needs another piece of the chunk, +lua_load calls the reader, +passing along its data parameter. +The reader must return a pointer to a block of memory +with a new piece of the chunk +and set size to the block size. +The block must exist until the reader function is called again. +To signal the end of the chunk, +the reader must return NULL or set size to zero. +The reader function may return pieces of any size greater than zero. + + + + + +

lua_register

+[-0, +0, e] +

void lua_register (lua_State *L,
+                   const char *name,
+                   lua_CFunction f);
+ +

+Sets the C function f as the new value of global name. +It is defined as a macro: + +

+     #define lua_register(L,n,f) \
+            (lua_pushcfunction(L, f), lua_setglobal(L, n))
+
+ + + + +

lua_remove

+[-1, +0, -] +

void lua_remove (lua_State *L, int index);
+ +

+Removes the element at the given valid index, +shifting down the elements above this index to fill the gap. +Cannot be called with a pseudo-index, +because a pseudo-index is not an actual stack position. + + + + + +

lua_replace

+[-1, +0, -] +

void lua_replace (lua_State *L, int index);
+ +

+Moves the top element into the given position (and pops it), +without shifting any element +(therefore replacing the value at the given position). + + + + + +

lua_resume

+[-?, +?, -] +

int lua_resume (lua_State *L, int narg);
+ +

+Starts and resumes a coroutine in a given thread. + + +

+To start a coroutine, you first create a new thread +(see lua_newthread); +then you push onto its stack the main function plus any arguments; +then you call lua_resume, +with narg being the number of arguments. +This call returns when the coroutine suspends or finishes its execution. +When it returns, the stack contains all values passed to lua_yield, +or all values returned by the body function. +lua_resume returns +LUA_YIELD if the coroutine yields, +0 if the coroutine finishes its execution +without errors, +or an error code in case of errors (see lua_pcall). +In case of errors, +the stack is not unwound, +so you can use the debug API over it. +The error message is on the top of the stack. +To restart a coroutine, you put on its stack only the values to +be passed as results from yield, +and then call lua_resume. + + + + + +

lua_setallocf

+[-0, +0, -] +

void lua_setallocf (lua_State *L, lua_Alloc f, void *ud);
+ +

+Changes the allocator function of a given state to f +with user data ud. + + + + + +

lua_setfenv

+[-1, +0, -] +

int lua_setfenv (lua_State *L, int index);
+ +

+Pops a table from the stack and sets it as +the new environment for the value at the given index. +If the value at the given index is +neither a function nor a thread nor a userdata, +lua_setfenv returns 0. +Otherwise it returns 1. + + + + + +

lua_setfield

+[-1, +0, e] +

void lua_setfield (lua_State *L, int index, const char *k);
+ +

+Does the equivalent to t[k] = v, +where t is the value at the given valid index +and v is the value at the top of the stack. + + +

+This function pops the value from the stack. +As in Lua, this function may trigger a metamethod +for the "newindex" event (see §2.8). + + + + + +

lua_setglobal

+[-1, +0, e] +

void lua_setglobal (lua_State *L, const char *name);
+ +

+Pops a value from the stack and +sets it as the new value of global name. +It is defined as a macro: + +

+     #define lua_setglobal(L,s)   lua_setfield(L, LUA_GLOBALSINDEX, s)
+
+ + + + +

lua_setmetatable

+[-1, +0, -] +

int lua_setmetatable (lua_State *L, int index);
+ +

+Pops a table from the stack and +sets it as the new metatable for the value at the given +acceptable index. + + + + + +

lua_settable

+[-2, +0, e] +

void lua_settable (lua_State *L, int index);
+ +

+Does the equivalent to t[k] = v, +where t is the value at the given valid index, +v is the value at the top of the stack, +and k is the value just below the top. + + +

+This function pops both the key and the value from the stack. +As in Lua, this function may trigger a metamethod +for the "newindex" event (see §2.8). + + + + + +

lua_settop

+[-?, +?, -] +

void lua_settop (lua_State *L, int index);
+ +

+Accepts any acceptable index, or 0, +and sets the stack top to this index. +If the new top is larger than the old one, +then the new elements are filled with nil. +If index is 0, then all stack elements are removed. + + + + + +

lua_State

+
typedef struct lua_State lua_State;
+ +

+Opaque structure that keeps the whole state of a Lua interpreter. +The Lua library is fully reentrant: +it has no global variables. +All information about a state is kept in this structure. + + +

+A pointer to this state must be passed as the first argument to +every function in the library, except to lua_newstate, +which creates a Lua state from scratch. + + + + + +

lua_status

+[-0, +0, -] +

int lua_status (lua_State *L);
+ +

+Returns the status of the thread L. + + +

+The status can be 0 for a normal thread, +an error code if the thread finished its execution with an error, +or LUA_YIELD if the thread is suspended. + + + + + +

lua_toboolean

+[-0, +0, -] +

int lua_toboolean (lua_State *L, int index);
+ +

+Converts the Lua value at the given acceptable index to a C boolean +value (0 or 1). +Like all tests in Lua, +lua_toboolean returns 1 for any Lua value +different from false and nil; +otherwise it returns 0. +It also returns 0 when called with a non-valid index. +(If you want to accept only actual boolean values, +use lua_isboolean to test the value's type.) + + + + + +

lua_tocfunction

+[-0, +0, -] +

lua_CFunction lua_tocfunction (lua_State *L, int index);
+ +

+Converts a value at the given acceptable index to a C function. +That value must be a C function; +otherwise, returns NULL. + + + + + +

lua_tointeger

+[-0, +0, -] +

lua_Integer lua_tointeger (lua_State *L, int index);
+ +

+Converts the Lua value at the given acceptable index +to the signed integral type lua_Integer. +The Lua value must be a number or a string convertible to a number +(see §2.2.1); +otherwise, lua_tointeger returns 0. + + +

+If the number is not an integer, +it is truncated in some non-specified way. + + + + + +

lua_tolstring

+[-0, +0, m] +

const char *lua_tolstring (lua_State *L, int index, size_t *len);
+ +

+Converts the Lua value at the given acceptable index to a C string. +If len is not NULL, +it also sets *len with the string length. +The Lua value must be a string or a number; +otherwise, the function returns NULL. +If the value is a number, +then lua_tolstring also +changes the actual value in the stack to a string. +(This change confuses lua_next +when lua_tolstring is applied to keys during a table traversal.) + + +

+lua_tolstring returns a fully aligned pointer +to a string inside the Lua state. +This string always has a zero ('\0') +after its last character (as in C), +but can contain other zeros in its body. +Because Lua has garbage collection, +there is no guarantee that the pointer returned by lua_tolstring +will be valid after the corresponding value is removed from the stack. + + + + + +

lua_tonumber

+[-0, +0, -] +

lua_Number lua_tonumber (lua_State *L, int index);
+ +

+Converts the Lua value at the given acceptable index +to the C type lua_Number (see lua_Number). +The Lua value must be a number or a string convertible to a number +(see §2.2.1); +otherwise, lua_tonumber returns 0. + + + + + +

lua_topointer

+[-0, +0, -] +

const void *lua_topointer (lua_State *L, int index);
+ +

+Converts the value at the given acceptable index to a generic +C pointer (void*). +The value can be a userdata, a table, a thread, or a function; +otherwise, lua_topointer returns NULL. +Different objects will give different pointers. +There is no way to convert the pointer back to its original value. + + +

+Typically this function is used only for debug information. + + + + + +

lua_tostring

+[-0, +0, m] +

const char *lua_tostring (lua_State *L, int index);
+ +

+Equivalent to lua_tolstring with len equal to NULL. + + + + + +

lua_tothread

+[-0, +0, -] +

lua_State *lua_tothread (lua_State *L, int index);
+ +

+Converts the value at the given acceptable index to a Lua thread +(represented as lua_State*). +This value must be a thread; +otherwise, the function returns NULL. + + + + + +

lua_touserdata

+[-0, +0, -] +

void *lua_touserdata (lua_State *L, int index);
+ +

+If the value at the given acceptable index is a full userdata, +returns its block address. +If the value is a light userdata, +returns its pointer. +Otherwise, returns NULL. + + + + + +

lua_type

+[-0, +0, -] +

int lua_type (lua_State *L, int index);
+ +

+Returns the type of the value in the given acceptable index, +or LUA_TNONE for a non-valid index +(that is, an index to an "empty" stack position). +The types returned by lua_type are coded by the following constants +defined in lua.h: +LUA_TNIL, +LUA_TNUMBER, +LUA_TBOOLEAN, +LUA_TSTRING, +LUA_TTABLE, +LUA_TFUNCTION, +LUA_TUSERDATA, +LUA_TTHREAD, +and +LUA_TLIGHTUSERDATA. + + + + + +

lua_typename

+[-0, +0, -] +

const char *lua_typename  (lua_State *L, int tp);
+ +

+Returns the name of the type encoded by the value tp, +which must be one the values returned by lua_type. + + + + + +

lua_Writer

+
typedef int (*lua_Writer) (lua_State *L,
+                           const void* p,
+                           size_t sz,
+                           void* ud);
+ +

+The type of the writer function used by lua_dump. +Every time it produces another piece of chunk, +lua_dump calls the writer, +passing along the buffer to be written (p), +its size (sz), +and the data parameter supplied to lua_dump. + + +

+The writer returns an error code: +0 means no errors; +any other value means an error and stops lua_dump from +calling the writer again. + + + + + +

lua_xmove

+[-?, +?, -] +

void lua_xmove (lua_State *from, lua_State *to, int n);
+ +

+Exchange values between different threads of the same global state. + + +

+This function pops n values from the stack from, +and pushes them onto the stack to. + + + + + +

lua_yield

+[-?, +?, -] +

int lua_yield  (lua_State *L, int nresults);
+ +

+Yields a coroutine. + + +

+This function should only be called as the +return expression of a C function, as follows: + +

+     return lua_yield (L, nresults);
+

+When a C function calls lua_yield in that way, +the running coroutine suspends its execution, +and the call to lua_resume that started this coroutine returns. +The parameter nresults is the number of values from the stack +that are passed as results to lua_resume. + + + + + + + +

3.8 - The Debug Interface

+ +

+Lua has no built-in debugging facilities. +Instead, it offers a special interface +by means of functions and hooks. +This interface allows the construction of different +kinds of debuggers, profilers, and other tools +that need "inside information" from the interpreter. + + + +

lua_Debug

+
typedef struct lua_Debug {
+  int event;
+  const char *name;           /* (n) */
+  const char *namewhat;       /* (n) */
+  const char *what;           /* (S) */
+  const char *source;         /* (S) */
+  int currentline;            /* (l) */
+  int nups;                   /* (u) number of upvalues */
+  int linedefined;            /* (S) */
+  int lastlinedefined;        /* (S) */
+  char short_src[LUA_IDSIZE]; /* (S) */
+  /* private part */
+  other fields
+} lua_Debug;
+ +

+A structure used to carry different pieces of +information about an active function. +lua_getstack fills only the private part +of this structure, for later use. +To fill the other fields of lua_Debug with useful information, +call lua_getinfo. + + +

+The fields of lua_Debug have the following meaning: + +

    + +
  • source: +If the function was defined in a string, +then source is that string. +If the function was defined in a file, +then source starts with a '@' followed by the file name. +
    • + +
  • short_src: +a "printable" version of source, to be used in error messages. +
    • + +
  • linedefined: +the line number where the definition of the function starts. +
    • + +
  • lastlinedefined: +the line number where the definition of the function ends. +
    • + +
  • what: +the string "Lua" if the function is a Lua function, +"C" if it is a C function, +"main" if it is the main part of a chunk, +and "tail" if it was a function that did a tail call. +In the latter case, +Lua has no other information about the function. +
    • + +
  • currentline: +the current line where the given function is executing. +When no line information is available, +currentline is set to -1. +
    • + +
  • name: +a reasonable name for the given function. +Because functions in Lua are first-class values, +they do not have a fixed name: +some functions can be the value of multiple global variables, +while others can be stored only in a table field. +The lua_getinfo function checks how the function was +called to find a suitable name. +If it cannot find a name, +then name is set to NULL. +
    • + +
  • namewhat: +explains the name field. +The value of namewhat can be +"global", "local", "method", +"field", "upvalue", or "" (the empty string), +according to how the function was called. +(Lua uses the empty string when no other option seems to apply.) +
    • + +
  • nups: +the number of upvalues of the function. +
    • + +
+ + + + +

lua_gethook

+[-0, +0, -] +

lua_Hook lua_gethook (lua_State *L);
+ +

+Returns the current hook function. + + + + + +

lua_gethookcount

+[-0, +0, -] +

int lua_gethookcount (lua_State *L);
+ +

+Returns the current hook count. + + + + + +

lua_gethookmask

+[-0, +0, -] +

int lua_gethookmask (lua_State *L);
+ +

+Returns the current hook mask. + + + + + +

lua_getinfo

+[-(0|1), +(0|1|2), m] +

int lua_getinfo (lua_State *L, const char *what, lua_Debug *ar);
+ +

+Returns information about a specific function or function invocation. + + +

+To get information about a function invocation, +the parameter ar must be a valid activation record that was +filled by a previous call to lua_getstack or +given as argument to a hook (see lua_Hook). + + +

+To get information about a function you push it onto the stack +and start the what string with the character '>'. +(In that case, +lua_getinfo pops the function in the top of the stack.) +For instance, to know in which line a function f was defined, +you can write the following code: + +

+     lua_Debug ar;
+     lua_getfield(L, LUA_GLOBALSINDEX, "f");  /* get global 'f' */
+     lua_getinfo(L, ">S", &ar);
+     printf("%d\n", ar.linedefined);
+
+ +

+Each character in the string what +selects some fields of the structure ar to be filled or +a value to be pushed on the stack: + +

    + +
  • 'n': fills in the field name and namewhat; +
    • + +
  • 'S': +fills in the fields source, short_src, +linedefined, lastlinedefined, and what; +
    • + +
  • 'l': fills in the field currentline; +
    • + +
  • 'u': fills in the field nups; +
    • + +
  • 'f': +pushes onto the stack the function that is +running at the given level; +
    • + +
  • 'L': +pushes onto the stack a table whose indices are the +numbers of the lines that are valid on the function. +(A valid line is a line with some associated code, +that is, a line where you can put a break point. +Non-valid lines include empty lines and comments.) +
    • + +
+ +

+This function returns 0 on error +(for instance, an invalid option in what). + + + + + +

lua_getlocal

+[-0, +(0|1), -] +

const char *lua_getlocal (lua_State *L, lua_Debug *ar, int n);
+ +

+Gets information about a local variable of a given activation record. +The parameter ar must be a valid activation record that was +filled by a previous call to lua_getstack or +given as argument to a hook (see lua_Hook). +The index n selects which local variable to inspect +(1 is the first parameter or active local variable, and so on, +until the last active local variable). +lua_getlocal pushes the variable's value onto the stack +and returns its name. + + +

+Variable names starting with '(' (open parentheses) +represent internal variables +(loop control variables, temporaries, and C function locals). + + +

+Returns NULL (and pushes nothing) +when the index is greater than +the number of active local variables. + + + + + +

lua_getstack

+[-0, +0, -] +

int lua_getstack (lua_State *L, int level, lua_Debug *ar);
+ +

+Get information about the interpreter runtime stack. + + +

+This function fills parts of a lua_Debug structure with +an identification of the activation record +of the function executing at a given level. +Level 0 is the current running function, +whereas level n+1 is the function that has called level n. +When there are no errors, lua_getstack returns 1; +when called with a level greater than the stack depth, +it returns 0. + + + + + +

lua_getupvalue

+[-0, +(0|1), -] +

const char *lua_getupvalue (lua_State *L, int funcindex, int n);
+ +

+Gets information about a closure's upvalue. +(For Lua functions, +upvalues are the external local variables that the function uses, +and that are consequently included in its closure.) +lua_getupvalue gets the index n of an upvalue, +pushes the upvalue's value onto the stack, +and returns its name. +funcindex points to the closure in the stack. +(Upvalues have no particular order, +as they are active through the whole function. +So, they are numbered in an arbitrary order.) + + +

+Returns NULL (and pushes nothing) +when the index is greater than the number of upvalues. +For C functions, this function uses the empty string "" +as a name for all upvalues. + + + + + +

lua_Hook

+
typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);
+ +

+Type for debugging hook functions. + + +

+Whenever a hook is called, its ar argument has its field +event set to the specific event that triggered the hook. +Lua identifies these events with the following constants: +LUA_HOOKCALL, LUA_HOOKRET, +LUA_HOOKTAILRET, LUA_HOOKLINE, +and LUA_HOOKCOUNT. +Moreover, for line events, the field currentline is also set. +To get the value of any other field in ar, +the hook must call lua_getinfo. +For return events, event can be LUA_HOOKRET, +the normal value, or LUA_HOOKTAILRET. +In the latter case, Lua is simulating a return from +a function that did a tail call; +in this case, it is useless to call lua_getinfo. + + +

+While Lua is running a hook, it disables other calls to hooks. +Therefore, if a hook calls back Lua to execute a function or a chunk, +this execution occurs without any calls to hooks. + + + + + +

lua_sethook

+[-0, +0, -] +

int lua_sethook (lua_State *L, lua_Hook f, int mask, int count);
+ +

+Sets the debugging hook function. + + +

+Argument f is the hook function. +mask specifies on which events the hook will be called: +it is formed by a bitwise or of the constants +LUA_MASKCALL, +LUA_MASKRET, +LUA_MASKLINE, +and LUA_MASKCOUNT. +The count argument is only meaningful when the mask +includes LUA_MASKCOUNT. +For each event, the hook is called as explained below: + +

    + +
  • The call hook: is called when the interpreter calls a function. +The hook is called just after Lua enters the new function, +before the function gets its arguments. +
    • + +
  • The return hook: is called when the interpreter returns from a function. +The hook is called just before Lua leaves the function. +You have no access to the values to be returned by the function. +
    • + +
  • The line hook: is called when the interpreter is about to +start the execution of a new line of code, +or when it jumps back in the code (even to the same line). +(This event only happens while Lua is executing a Lua function.) +
    • + +
  • The count hook: is called after the interpreter executes every +count instructions. +(This event only happens while Lua is executing a Lua function.) +
    • + +
+ +

+A hook is disabled by setting mask to zero. + + + + + +

lua_setlocal

+[-(0|1), +0, -] +

const char *lua_setlocal (lua_State *L, lua_Debug *ar, int n);
+ +

+Sets the value of a local variable of a given activation record. +Parameters ar and n are as in lua_getlocal +(see lua_getlocal). +lua_setlocal assigns the value at the top of the stack +to the variable and returns its name. +It also pops the value from the stack. + + +

+Returns NULL (and pops nothing) +when the index is greater than +the number of active local variables. + + + + + +

lua_setupvalue

+[-(0|1), +0, -] +

const char *lua_setupvalue (lua_State *L, int funcindex, int n);
+ +

+Sets the value of a closure's upvalue. +It assigns the value at the top of the stack +to the upvalue and returns its name. +It also pops the value from the stack. +Parameters funcindex and n are as in the lua_getupvalue +(see lua_getupvalue). + + +

+Returns NULL (and pops nothing) +when the index is greater than the number of upvalues. + + + + + + + +

4 - The Auxiliary Library

+ +

+ +The auxiliary library provides several convenient functions +to interface C with Lua. +While the basic API provides the primitive functions for all +interactions between C and Lua, +the auxiliary library provides higher-level functions for some +common tasks. + + +

+All functions from the auxiliary library +are defined in header file lauxlib.h and +have a prefix luaL_. + + +

+All functions in the auxiliary library are built on +top of the basic API, +and so they provide nothing that cannot be done with this API. + + +

+Several functions in the auxiliary library are used to +check C function arguments. +Their names are always luaL_check* or luaL_opt*. +All of these functions throw an error if the check is not satisfied. +Because the error message is formatted for arguments +(e.g., "bad argument #1"), +you should not use these functions for other stack values. + + + +

4.1 - Functions and Types

+ +

+Here we list all functions and types from the auxiliary library +in alphabetical order. + + + +

luaL_addchar

+[-0, +0, m] +

void luaL_addchar (luaL_Buffer *B, char c);
+ +

+Adds the character c to the buffer B +(see luaL_Buffer). + + + + + +

luaL_addlstring

+[-0, +0, m] +

void luaL_addlstring (luaL_Buffer *B, const char *s, size_t l);
+ +

+Adds the string pointed to by s with length l to +the buffer B +(see luaL_Buffer). +The string may contain embedded zeros. + + + + + +

luaL_addsize

+[-0, +0, m] +

void luaL_addsize (luaL_Buffer *B, size_t n);
+ +

+Adds to the buffer B (see luaL_Buffer) +a string of length n previously copied to the +buffer area (see luaL_prepbuffer). + + + + + +

luaL_addstring

+[-0, +0, m] +

void luaL_addstring (luaL_Buffer *B, const char *s);
+ +

+Adds the zero-terminated string pointed to by s +to the buffer B +(see luaL_Buffer). +The string may not contain embedded zeros. + + + + + +

luaL_addvalue

+[-1, +0, m] +

void luaL_addvalue (luaL_Buffer *B);
+ +

+Adds the value at the top of the stack +to the buffer B +(see luaL_Buffer). +Pops the value. + + +

+This is the only function on string buffers that can (and must) +be called with an extra element on the stack, +which is the value to be added to the buffer. + + + + + +

luaL_argcheck

+[-0, +0, v] +

void luaL_argcheck (lua_State *L,
+                    int cond,
+                    int narg,
+                    const char *extramsg);
+ +

+Checks whether cond is true. +If not, raises an error with the following message, +where func is retrieved from the call stack: + +

+     bad argument #<narg> to <func> (<extramsg>)
+
+ + + + +

luaL_argerror

+[-0, +0, v] +

int luaL_argerror (lua_State *L, int narg, const char *extramsg);
+ +

+Raises an error with the following message, +where func is retrieved from the call stack: + +

+     bad argument #<narg> to <func> (<extramsg>)
+
+ +

+This function never returns, +but it is an idiom to use it in C functions +as return luaL_argerror(args). + + + + + +

luaL_Buffer

+
typedef struct luaL_Buffer luaL_Buffer;
+ +

+Type for a string buffer. + + +

+A string buffer allows C code to build Lua strings piecemeal. +Its pattern of use is as follows: + +

    + +
  • First you declare a variable b of type luaL_Buffer.
    • + +
  • Then you initialize it with a call luaL_buffinit(L, &b).
    • + +
  • +Then you add string pieces to the buffer calling any of +the luaL_add* functions. +
    • + +
  • +You finish by calling luaL_pushresult(&b). +This call leaves the final string on the top of the stack. +
    • + +
+ +

+During its normal operation, +a string buffer uses a variable number of stack slots. +So, while using a buffer, you cannot assume that you know where +the top of the stack is. +You can use the stack between successive calls to buffer operations +as long as that use is balanced; +that is, +when you call a buffer operation, +the stack is at the same level +it was immediately after the previous buffer operation. +(The only exception to this rule is luaL_addvalue.) +After calling luaL_pushresult the stack is back to its +level when the buffer was initialized, +plus the final string on its top. + + + + + +

luaL_buffinit

+[-0, +0, -] +

void luaL_buffinit (lua_State *L, luaL_Buffer *B);
+ +

+Initializes a buffer B. +This function does not allocate any space; +the buffer must be declared as a variable +(see luaL_Buffer). + + + + + +

luaL_callmeta

+[-0, +(0|1), e] +

int luaL_callmeta (lua_State *L, int obj, const char *e);
+ +

+Calls a metamethod. + + +

+If the object at index obj has a metatable and this +metatable has a field e, +this function calls this field and passes the object as its only argument. +In this case this function returns 1 and pushes onto the +stack the value returned by the call. +If there is no metatable or no metamethod, +this function returns 0 (without pushing any value on the stack). + + + + + +

luaL_checkany

+[-0, +0, v] +

void luaL_checkany (lua_State *L, int narg);
+ +

+Checks whether the function has an argument +of any type (including nil) at position narg. + + + + + +

luaL_checkint

+[-0, +0, v] +

int luaL_checkint (lua_State *L, int narg);
+ +

+Checks whether the function argument narg is a number +and returns this number cast to an int. + + + + + +

luaL_checkinteger

+[-0, +0, v] +

lua_Integer luaL_checkinteger (lua_State *L, int narg);
+ +

+Checks whether the function argument narg is a number +and returns this number cast to a lua_Integer. + + + + + +

luaL_checklong

+[-0, +0, v] +

long luaL_checklong (lua_State *L, int narg);
+ +

+Checks whether the function argument narg is a number +and returns this number cast to a long. + + + + + +

luaL_checklstring

+[-0, +0, v] +

const char *luaL_checklstring (lua_State *L, int narg, size_t *l);
+ +

+Checks whether the function argument narg is a string +and returns this string; +if l is not NULL fills *l +with the string's length. + + +

+This function uses lua_tolstring to get its result, +so all conversions and caveats of that function apply here. + + + + + +

luaL_checknumber

+[-0, +0, v] +

lua_Number luaL_checknumber (lua_State *L, int narg);
+ +

+Checks whether the function argument narg is a number +and returns this number. + + + + + +

luaL_checkoption

+[-0, +0, v] +

int luaL_checkoption (lua_State *L,
+                      int narg,
+                      const char *def,
+                      const char *const lst[]);
+ +

+Checks whether the function argument narg is a string and +searches for this string in the array lst +(which must be NULL-terminated). +Returns the index in the array where the string was found. +Raises an error if the argument is not a string or +if the string cannot be found. + + +

+If def is not NULL, +the function uses def as a default value when +there is no argument narg or if this argument is nil. + + +

+This is a useful function for mapping strings to C enums. +(The usual convention in Lua libraries is +to use strings instead of numbers to select options.) + + + + + +

luaL_checkstack

+[-0, +0, v] +

void luaL_checkstack (lua_State *L, int sz, const char *msg);
+ +

+Grows the stack size to top + sz elements, +raising an error if the stack cannot grow to that size. +msg is an additional text to go into the error message. + + + + + +

luaL_checkstring

+[-0, +0, v] +

const char *luaL_checkstring (lua_State *L, int narg);
+ +

+Checks whether the function argument narg is a string +and returns this string. + + +

+This function uses lua_tolstring to get its result, +so all conversions and caveats of that function apply here. + + + + + +

luaL_checktype

+[-0, +0, v] +

void luaL_checktype (lua_State *L, int narg, int t);
+ +

+Checks whether the function argument narg has type t. +See lua_type for the encoding of types for t. + + + + + +

luaL_checkudata

+[-0, +0, v] +

void *luaL_checkudata (lua_State *L, int narg, const char *tname);
+ +

+Checks whether the function argument narg is a userdata +of the type tname (see luaL_newmetatable). + + + + + +

luaL_dofile

+[-0, +?, m] +

int luaL_dofile (lua_State *L, const char *filename);
+ +

+Loads and runs the given file. +It is defined as the following macro: + +

+     (luaL_loadfile(L, filename) || lua_pcall(L, 0, LUA_MULTRET, 0))
+

+It returns 0 if there are no errors +or 1 in case of errors. + + + + + +

luaL_dostring

+[-0, +?, m] +

int luaL_dostring (lua_State *L, const char *str);
+ +

+Loads and runs the given string. +It is defined as the following macro: + +

+     (luaL_loadstring(L, str) || lua_pcall(L, 0, LUA_MULTRET, 0))
+

+It returns 0 if there are no errors +or 1 in case of errors. + + + + + +

luaL_error

+[-0, +0, v] +

int luaL_error (lua_State *L, const char *fmt, ...);
+ +

+Raises an error. +The error message format is given by fmt +plus any extra arguments, +following the same rules of lua_pushfstring. +It also adds at the beginning of the message the file name and +the line number where the error occurred, +if this information is available. + + +

+This function never returns, +but it is an idiom to use it in C functions +as return luaL_error(args). + + + + + +

luaL_getmetafield

+[-0, +(0|1), m] +

int luaL_getmetafield (lua_State *L, int obj, const char *e);
+ +

+Pushes onto the stack the field e from the metatable +of the object at index obj. +If the object does not have a metatable, +or if the metatable does not have this field, +returns 0 and pushes nothing. + + + + + +

luaL_getmetatable

+[-0, +1, -] +

void luaL_getmetatable (lua_State *L, const char *tname);
+ +

+Pushes onto the stack the metatable associated with name tname +in the registry (see luaL_newmetatable). + + + + + +

luaL_gsub

+[-0, +1, m] +

const char *luaL_gsub (lua_State *L,
+                       const char *s,
+                       const char *p,
+                       const char *r);
+ +

+Creates a copy of string s by replacing +any occurrence of the string p +with the string r. +Pushes the resulting string on the stack and returns it. + + + + + +

luaL_loadbuffer

+[-0, +1, m] +

int luaL_loadbuffer (lua_State *L,
+                     const char *buff,
+                     size_t sz,
+                     const char *name);
+ +

+Loads a buffer as a Lua chunk. +This function uses lua_load to load the chunk in the +buffer pointed to by buff with size sz. + + +

+This function returns the same results as lua_load. +name is the chunk name, +used for debug information and error messages. + + + + + +

luaL_loadfile

+[-0, +1, m] +

int luaL_loadfile (lua_State *L, const char *filename);
+ +

+Loads a file as a Lua chunk. +This function uses lua_load to load the chunk in the file +named filename. +If filename is NULL, +then it loads from the standard input. +The first line in the file is ignored if it starts with a #. + + +

+This function returns the same results as lua_load, +but it has an extra error code LUA_ERRFILE +if it cannot open/read the file. + + +

+As lua_load, this function only loads the chunk; +it does not run it. + + + + + +

luaL_loadstring

+[-0, +1, m] +

int luaL_loadstring (lua_State *L, const char *s);
+ +

+Loads a string as a Lua chunk. +This function uses lua_load to load the chunk in +the zero-terminated string s. + + +

+This function returns the same results as lua_load. + + +

+Also as lua_load, this function only loads the chunk; +it does not run it. + + + + + +

luaL_newmetatable

+[-0, +1, m] +

int luaL_newmetatable (lua_State *L, const char *tname);
+ +

+If the registry already has the key tname, +returns 0. +Otherwise, +creates a new table to be used as a metatable for userdata, +adds it to the registry with key tname, +and returns 1. + + +

+In both cases pushes onto the stack the final value associated +with tname in the registry. + + + + + +

luaL_newstate

+[-0, +0, -] +

lua_State *luaL_newstate (void);
+ +

+Creates a new Lua state. +It calls lua_newstate with an +allocator based on the standard C realloc function +and then sets a panic function (see lua_atpanic) that prints +an error message to the standard error output in case of fatal +errors. + + +

+Returns the new state, +or NULL if there is a memory allocation error. + + + + + +

luaL_openlibs

+[-0, +0, m] +

void luaL_openlibs (lua_State *L);
+ +

+Opens all standard Lua libraries into the given state. + + + + + +

luaL_optint

+[-0, +0, v] +

int luaL_optint (lua_State *L, int narg, int d);
+ +

+If the function argument narg is a number, +returns this number cast to an int. +If this argument is absent or is nil, +returns d. +Otherwise, raises an error. + + + + + +

luaL_optinteger

+[-0, +0, v] +

lua_Integer luaL_optinteger (lua_State *L,
+                             int narg,
+                             lua_Integer d);
+ +

+If the function argument narg is a number, +returns this number cast to a lua_Integer. +If this argument is absent or is nil, +returns d. +Otherwise, raises an error. + + + + + +

luaL_optlong

+[-0, +0, v] +

long luaL_optlong (lua_State *L, int narg, long d);
+ +

+If the function argument narg is a number, +returns this number cast to a long. +If this argument is absent or is nil, +returns d. +Otherwise, raises an error. + + + + + +

luaL_optlstring

+[-0, +0, v] +

const char *luaL_optlstring (lua_State *L,
+                             int narg,
+                             const char *d,
+                             size_t *l);
+ +

+If the function argument narg is a string, +returns this string. +If this argument is absent or is nil, +returns d. +Otherwise, raises an error. + + +

+If l is not NULL, +fills the position *l with the results's length. + + + + + +

luaL_optnumber

+[-0, +0, v] +

lua_Number luaL_optnumber (lua_State *L, int narg, lua_Number d);
+ +

+If the function argument narg is a number, +returns this number. +If this argument is absent or is nil, +returns d. +Otherwise, raises an error. + + + + + +

luaL_optstring

+[-0, +0, v] +

const char *luaL_optstring (lua_State *L,
+                            int narg,
+                            const char *d);
+ +

+If the function argument narg is a string, +returns this string. +If this argument is absent or is nil, +returns d. +Otherwise, raises an error. + + + + + +

luaL_prepbuffer

+[-0, +0, -] +

char *luaL_prepbuffer (luaL_Buffer *B);
+ +

+Returns an address to a space of size LUAL_BUFFERSIZE +where you can copy a string to be added to buffer B +(see luaL_Buffer). +After copying the string into this space you must call +luaL_addsize with the size of the string to actually add +it to the buffer. + + + + + +

luaL_pushresult

+[-?, +1, m] +

void luaL_pushresult (luaL_Buffer *B);
+ +

+Finishes the use of buffer B leaving the final string on +the top of the stack. + + + + + +

luaL_ref

+[-1, +0, m] +

int luaL_ref (lua_State *L, int t);
+ +

+Creates and returns a reference, +in the table at index t, +for the object at the top of the stack (and pops the object). + + +

+A reference is a unique integer key. +As long as you do not manually add integer keys into table t, +luaL_ref ensures the uniqueness of the key it returns. +You can retrieve an object referred by reference r +by calling lua_rawgeti(L, t, r). +Function luaL_unref frees a reference and its associated object. + + +

+If the object at the top of the stack is nil, +luaL_ref returns the constant LUA_REFNIL. +The constant LUA_NOREF is guaranteed to be different +from any reference returned by luaL_ref. + + + + + +

luaL_Reg

+
typedef struct luaL_Reg {
+  const char *name;
+  lua_CFunction func;
+} luaL_Reg;
+ +

+Type for arrays of functions to be registered by +luaL_register. +name is the function name and func is a pointer to +the function. +Any array of luaL_Reg must end with an sentinel entry +in which both name and func are NULL. + + + + + +

luaL_register

+[-(0|1), +1, m] +

void luaL_register (lua_State *L,
+                    const char *libname,
+                    const luaL_Reg *l);
+ +

+Opens a library. + + +

+When called with libname equal to NULL, +it simply registers all functions in the list l +(see luaL_Reg) into the table on the top of the stack. + + +

+When called with a non-null libname, +luaL_register creates a new table t, +sets it as the value of the global variable libname, +sets it as the value of package.loaded[libname], +and registers on it all functions in the list l. +If there is a table in package.loaded[libname] or in +variable libname, +reuses this table instead of creating a new one. + + +

+In any case the function leaves the table +on the top of the stack. + + + + + +

luaL_typename

+[-0, +0, -] +

const char *luaL_typename (lua_State *L, int index);
+ +

+Returns the name of the type of the value at the given index. + + + + + +

luaL_typerror

+[-0, +0, v] +

int luaL_typerror (lua_State *L, int narg, const char *tname);
+ +

+Generates an error with a message like the following: + +

+     location: bad argument narg to 'func' (tname expected, got rt)
+

+where location is produced by luaL_where, +func is the name of the current function, +and rt is the type name of the actual argument. + + + + + +

luaL_unref

+[-0, +0, -] +

void luaL_unref (lua_State *L, int t, int ref);
+ +

+Releases reference ref from the table at index t +(see luaL_ref). +The entry is removed from the table, +so that the referred object can be collected. +The reference ref is also freed to be used again. + + +

+If ref is LUA_NOREF or LUA_REFNIL, +luaL_unref does nothing. + + + + + +

luaL_where

+[-0, +1, m] +

void luaL_where (lua_State *L, int lvl);
+ +

+Pushes onto the stack a string identifying the current position +of the control at level lvl in the call stack. +Typically this string has the following format: + +

+     chunkname:currentline:
+

+Level 0 is the running function, +level 1 is the function that called the running function, +etc. + + +

+This function is used to build a prefix for error messages. + + + + + + + +

5 - Standard Libraries

+ +

+The standard Lua libraries provide useful functions +that are implemented directly through the C API. +Some of these functions provide essential services to the language +(e.g., type and getmetatable); +others provide access to "outside" services (e.g., I/O); +and others could be implemented in Lua itself, +but are quite useful or have critical performance requirements that +deserve an implementation in C (e.g., table.sort). + + +

+All libraries are implemented through the official C API +and are provided as separate C modules. +Currently, Lua has the following standard libraries: + +

    + +
  • basic library, which includes the coroutine sub-library;
    • + +
  • package library;
    • + +
  • string manipulation;
    • + +
  • table manipulation;
    • + +
  • mathematical functions (sin, log, etc.);
    • + +
  • input and output;
    • + +
  • operating system facilities;
    • + +
  • debug facilities.
    • + +

+Except for the basic and package libraries, +each library provides all its functions as fields of a global table +or as methods of its objects. + + +

+To have access to these libraries, +the C host program should call the luaL_openlibs function, +which opens all standard libraries. +Alternatively, +it can open them individually by calling +luaopen_base (for the basic library), +luaopen_package (for the package library), +luaopen_string (for the string library), +luaopen_table (for the table library), +luaopen_math (for the mathematical library), +luaopen_io (for the I/O library), +luaopen_os (for the Operating System library), +and luaopen_debug (for the debug library). +These functions are declared in lualib.h +and should not be called directly: +you must call them like any other Lua C function, +e.g., by using lua_call. + + + +

5.1 - Basic Functions

+ +

+The basic library provides some core functions to Lua. +If you do not include this library in your application, +you should check carefully whether you need to provide +implementations for some of its facilities. + + +

+

assert (v [, message])

+Issues an error when +the value of its argument v is false (i.e., nil or false); +otherwise, returns all its arguments. +message is an error message; +when absent, it defaults to "assertion failed!" + + + + +

+

collectgarbage ([opt [, arg]])

+ + +

+This function is a generic interface to the garbage collector. +It performs different functions according to its first argument, opt: + +

    + +
  • "collect": +performs a full garbage-collection cycle. +This is the default option. +
    • + +
  • "stop": +stops the garbage collector. +
    • + +
  • "restart": +restarts the garbage collector. +
    • + +
  • "count": +returns the total memory in use by Lua (in Kbytes). +
    • + +
  • "step": +performs a garbage-collection step. +The step "size" is controlled by arg +(larger values mean more steps) in a non-specified way. +If you want to control the step size +you must experimentally tune the value of arg. +Returns true if the step finished a collection cycle. +
    • + +
  • "setpause": +sets arg as the new value for the pause of +the collector (see §2.10). +Returns the previous value for pause. +
    • + +
  • "setstepmul": +sets arg as the new value for the step multiplier of +the collector (see §2.10). +Returns the previous value for step. +
    • + +
+ + + +

+

dofile ([filename])

+Opens the named file and executes its contents as a Lua chunk. +When called without arguments, +dofile executes the contents of the standard input (stdin). +Returns all values returned by the chunk. +In case of errors, dofile propagates the error +to its caller (that is, dofile does not run in protected mode). + + + + +

+

error (message [, level])

+Terminates the last protected function called +and returns message as the error message. +Function error never returns. + + +

+Usually, error adds some information about the error position +at the beginning of the message. +The level argument specifies how to get the error position. +With level 1 (the default), the error position is where the +error function was called. +Level 2 points the error to where the function +that called error was called; and so on. +Passing a level 0 avoids the addition of error position information +to the message. + + + + +

+

_G

+A global variable (not a function) that +holds the global environment (that is, _G._G = _G). +Lua itself does not use this variable; +changing its value does not affect any environment, +nor vice-versa. +(Use setfenv to change environments.) + + + + +

+

getfenv ([f])

+Returns the current environment in use by the function. +f can be a Lua function or a number +that specifies the function at that stack level: +Level 1 is the function calling getfenv. +If the given function is not a Lua function, +or if f is 0, +getfenv returns the global environment. +The default for f is 1. + + + + +

+

getmetatable (object)

+ + +

+If object does not have a metatable, returns nil. +Otherwise, +if the object's metatable has a "__metatable" field, +returns the associated value. +Otherwise, returns the metatable of the given object. + + + + +

+

ipairs (t)

+ + +

+Returns three values: an iterator function, the table t, and 0, +so that the construction + +

+     for i,v in ipairs(t) do body end
+

+will iterate over the pairs (1,t[1]), (2,t[2]), ···, +up to the first integer key absent from the table. + + + + +

+

load (func [, chunkname])

+ + +

+Loads a chunk using function func to get its pieces. +Each call to func must return a string that concatenates +with previous results. +A return of an empty string, nil, or no value signals the end of the chunk. + + +

+If there are no errors, +returns the compiled chunk as a function; +otherwise, returns nil plus the error message. +The environment of the returned function is the global environment. + + +

+chunkname is used as the chunk name for error messages +and debug information. +When absent, +it defaults to "=(load)". + + + + +

+

loadfile ([filename])

+ + +

+Similar to load, +but gets the chunk from file filename +or from the standard input, +if no file name is given. + + + + +

+

loadstring (string [, chunkname])

+ + +

+Similar to load, +but gets the chunk from the given string. + + +

+To load and run a given string, use the idiom + +

+     assert(loadstring(s))()
+
+ +

+When absent, +chunkname defaults to the given string. + + + + +

+

next (table [, index])

+ + +

+Allows a program to traverse all fields of a table. +Its first argument is a table and its second argument +is an index in this table. +next returns the next index of the table +and its associated value. +When called with nil as its second argument, +next returns an initial index +and its associated value. +When called with the last index, +or with nil in an empty table, +next returns nil. +If the second argument is absent, then it is interpreted as nil. +In particular, +you can use next(t) to check whether a table is empty. + + +

+The order in which the indices are enumerated is not specified, +even for numeric indices. +(To traverse a table in numeric order, +use a numerical for or the ipairs function.) + + +

+The behavior of next is undefined if, +during the traversal, +you assign any value to a non-existent field in the table. +You may however modify existing fields. +In particular, you may clear existing fields. + + + + +

+

pairs (t)

+ + +

+Returns three values: the next function, the table t, and nil, +so that the construction + +

+     for k,v in pairs(t) do body end
+

+will iterate over all key–value pairs of table t. + + +

+See function next for the caveats of modifying +the table during its traversal. + + + + +

+

pcall (f, arg1, ···)

+ + +

+Calls function f with +the given arguments in protected mode. +This means that any error inside f is not propagated; +instead, pcall catches the error +and returns a status code. +Its first result is the status code (a boolean), +which is true if the call succeeds without errors. +In such case, pcall also returns all results from the call, +after this first result. +In case of any error, pcall returns false plus the error message. + + + + +

+

print (···)

+Receives any number of arguments, +and prints their values to stdout, +using the tostring function to convert them to strings. +print is not intended for formatted output, +but only as a quick way to show a value, +typically for debugging. +For formatted output, use string.format. + + + + +

+

rawequal (v1, v2)

+Checks whether v1 is equal to v2, +without invoking any metamethod. +Returns a boolean. + + + + +

+

rawget (table, index)

+Gets the real value of table[index], +without invoking any metamethod. +table must be a table; +index may be any value. + + + + +

+

rawset (table, index, value)

+Sets the real value of table[index] to value, +without invoking any metamethod. +table must be a table, +index any value different from nil, +and value any Lua value. + + +

+This function returns table. + + + + +

+

select (index, ···)

+ + +

+If index is a number, +returns all arguments after argument number index. +Otherwise, index must be the string "#", +and select returns the total number of extra arguments it received. + + + + +

+

setfenv (f, table)

+ + +

+Sets the environment to be used by the given function. +f can be a Lua function or a number +that specifies the function at that stack level: +Level 1 is the function calling setfenv. +setfenv returns the given function. + + +

+As a special case, when f is 0 setfenv changes +the environment of the running thread. +In this case, setfenv returns no values. + + + + +

+

setmetatable (table, metatable)

+ + +

+Sets the metatable for the given table. +(You cannot change the metatable of other types from Lua, only from C.) +If metatable is nil, +removes the metatable of the given table. +If the original metatable has a "__metatable" field, +raises an error. + + +

+This function returns table. + + + + +

+

tonumber (e [, base])

+Tries to convert its argument to a number. +If the argument is already a number or a string convertible +to a number, then tonumber returns this number; +otherwise, it returns nil. + + +

+An optional argument specifies the base to interpret the numeral. +The base may be any integer between 2 and 36, inclusive. +In bases above 10, the letter 'A' (in either upper or lower case) +represents 10, 'B' represents 11, and so forth, +with 'Z' representing 35. +In base 10 (the default), the number can have a decimal part, +as well as an optional exponent part (see §2.1). +In other bases, only unsigned integers are accepted. + + + + +

+

tostring (e)

+Receives an argument of any type and +converts it to a string in a reasonable format. +For complete control of how numbers are converted, +use string.format. + + +

+If the metatable of e has a "__tostring" field, +then tostring calls the corresponding value +with e as argument, +and uses the result of the call as its result. + + + + +

+

type (v)

+Returns the type of its only argument, coded as a string. +The possible results of this function are +"nil" (a string, not the value nil), +"number", +"string", +"boolean", +"table", +"function", +"thread", +and "userdata". + + + + +

+

unpack (list [, i [, j]])

+Returns the elements from the given table. +This function is equivalent to + +
+     return list[i], list[i+1], ···, list[j]
+

+except that the above code can be written only for a fixed number +of elements. +By default, i is 1 and j is the length of the list, +as defined by the length operator (see §2.5.5). + + + + +

+

_VERSION

+A global variable (not a function) that +holds a string containing the current interpreter version. +The current contents of this variable is "Lua 5.1". + + + + +

+

xpcall (f, err)

+ + +

+This function is similar to pcall, +except that you can set a new error handler. + + +

+xpcall calls function f in protected mode, +using err as the error handler. +Any error inside f is not propagated; +instead, xpcall catches the error, +calls the err function with the original error object, +and returns a status code. +Its first result is the status code (a boolean), +which is true if the call succeeds without errors. +In this case, xpcall also returns all results from the call, +after this first result. +In case of any error, +xpcall returns false plus the result from err. + + + + + + + +

5.2 - Coroutine Manipulation

+ +

+The operations related to coroutines comprise a sub-library of +the basic library and come inside the table coroutine. +See §2.11 for a general description of coroutines. + + +

+

coroutine.create (f)

+ + +

+Creates a new coroutine, with body f. +f must be a Lua function. +Returns this new coroutine, +an object with type "thread". + + + + +

+

coroutine.resume (co [, val1, ···])

+ + +

+Starts or continues the execution of coroutine co. +The first time you resume a coroutine, +it starts running its body. +The values val1, ··· are passed +as the arguments to the body function. +If the coroutine has yielded, +resume restarts it; +the values val1, ··· are passed +as the results from the yield. + + +

+If the coroutine runs without any errors, +resume returns true plus any values passed to yield +(if the coroutine yields) or any values returned by the body function +(if the coroutine terminates). +If there is any error, +resume returns false plus the error message. + + + + +

+

coroutine.running ()

+ + +

+Returns the running coroutine, +or nil when called by the main thread. + + + + +

+

coroutine.status (co)

+ + +

+Returns the status of coroutine co, as a string: +"running", +if the coroutine is running (that is, it called status); +"suspended", if the coroutine is suspended in a call to yield, +or if it has not started running yet; +"normal" if the coroutine is active but not running +(that is, it has resumed another coroutine); +and "dead" if the coroutine has finished its body function, +or if it has stopped with an error. + + + + +

+

coroutine.wrap (f)

+ + +

+Creates a new coroutine, with body f. +f must be a Lua function. +Returns a function that resumes the coroutine each time it is called. +Any arguments passed to the function behave as the +extra arguments to resume. +Returns the same values returned by resume, +except the first boolean. +In case of error, propagates the error. + + + + +

+

coroutine.yield (···)

+ + +

+Suspends the execution of the calling coroutine. +The coroutine cannot be running a C function, +a metamethod, or an iterator. +Any arguments to yield are passed as extra results to resume. + + + + + + + +

5.3 - Modules

+ +

+The package library provides basic +facilities for loading and building modules in Lua. +It exports two of its functions directly in the global environment: +require and module. +Everything else is exported in a table package. + + +

+

module (name [, ···])

+ + +

+Creates a module. +If there is a table in package.loaded[name], +this table is the module. +Otherwise, if there is a global table t with the given name, +this table is the module. +Otherwise creates a new table t and +sets it as the value of the global name and +the value of package.loaded[name]. +This function also initializes t._NAME with the given name, +t._M with the module (t itself), +and t._PACKAGE with the package name +(the full module name minus last component; see below). +Finally, module sets t as the new environment +of the current function and the new value of package.loaded[name], +so that require returns t. + + +

+If name is a compound name +(that is, one with components separated by dots), +module creates (or reuses, if they already exist) +tables for each component. +For instance, if name is a.b.c, +then module stores the module table in field c of +field b of global a. + + +

+This function can receive optional options after +the module name, +where each option is a function to be applied over the module. + + + + +

+

require (modname)

+ + +

+Loads the given module. +The function starts by looking into the package.loaded table +to determine whether modname is already loaded. +If it is, then require returns the value stored +at package.loaded[modname]. +Otherwise, it tries to find a loader for the module. + + +

+To find a loader, +require is guided by the package.loaders array. +By changing this array, +we can change how require looks for a module. +The following explanation is based on the default configuration +for package.loaders. + + +

+First require queries package.preload[modname]. +If it has a value, +this value (which should be a function) is the loader. +Otherwise require searches for a Lua loader using the +path stored in package.path. +If that also fails, it searches for a C loader using the +path stored in package.cpath. +If that also fails, +it tries an all-in-one loader (see package.loaders). + + +

+Once a loader is found, +require calls the loader with a single argument, modname. +If the loader returns any value, +require assigns the returned value to package.loaded[modname]. +If the loader returns no value and +has not assigned any value to package.loaded[modname], +then require assigns true to this entry. +In any case, require returns the +final value of package.loaded[modname]. + + +

+If there is any error loading or running the module, +or if it cannot find any loader for the module, +then require signals an error. + + + + +

+

package.cpath

+ + +

+The path used by require to search for a C loader. + + +

+Lua initializes the C path package.cpath in the same way +it initializes the Lua path package.path, +using the environment variable LUA_CPATH +or a default path defined in luaconf.h. + + + + +

+ +

package.loaded

+ + +

+A table used by require to control which +modules are already loaded. +When you require a module modname and +package.loaded[modname] is not false, +require simply returns the value stored there. + + + + +

+

package.loaders

+ + +

+A table used by require to control how to load modules. + + +

+Each entry in this table is a searcher function. +When looking for a module, +require calls each of these searchers in ascending order, +with the module name (the argument given to require) as its +sole parameter. +The function can return another function (the module loader) +or a string explaining why it did not find that module +(or nil if it has nothing to say). +Lua initializes this table with four functions. + + +

+The first searcher simply looks for a loader in the +package.preload table. + + +

+The second searcher looks for a loader as a Lua library, +using the path stored at package.path. +A path is a sequence of templates separated by semicolons. +For each template, +the searcher will change each interrogation +mark in the template by filename, +which is the module name with each dot replaced by a +"directory separator" (such as "/" in Unix); +then it will try to open the resulting file name. +So, for instance, if the Lua path is the string + +

+     "./?.lua;./?.lc;/usr/local/?/init.lua"
+

+the search for a Lua file for module foo +will try to open the files +./foo.lua, ./foo.lc, and +/usr/local/foo/init.lua, in that order. + + +

+The third searcher looks for a loader as a C library, +using the path given by the variable package.cpath. +For instance, +if the C path is the string + +

+     "./?.so;./?.dll;/usr/local/?/init.so"
+

+the searcher for module foo +will try to open the files ./foo.so, ./foo.dll, +and /usr/local/foo/init.so, in that order. +Once it finds a C library, +this searcher first uses a dynamic link facility to link the +application with the library. +Then it tries to find a C function inside the library to +be used as the loader. +The name of this C function is the string "luaopen_" +concatenated with a copy of the module name where each dot +is replaced by an underscore. +Moreover, if the module name has a hyphen, +its prefix up to (and including) the first hyphen is removed. +For instance, if the module name is a.v1-b.c, +the function name will be luaopen_b_c. + + +

+The fourth searcher tries an all-in-one loader. +It searches the C path for a library for +the root name of the given module. +For instance, when requiring a.b.c, +it will search for a C library for a. +If found, it looks into it for an open function for +the submodule; +in our example, that would be luaopen_a_b_c. +With this facility, a package can pack several C submodules +into one single library, +with each submodule keeping its original open function. + + + + +

+

package.loadlib (libname, funcname)

+ + +

+Dynamically links the host program with the C library libname. +Inside this library, looks for a function funcname +and returns this function as a C function. +(So, funcname must follow the protocol (see lua_CFunction)). + + +

+This is a low-level function. +It completely bypasses the package and module system. +Unlike require, +it does not perform any path searching and +does not automatically adds extensions. +libname must be the complete file name of the C library, +including if necessary a path and extension. +funcname must be the exact name exported by the C library +(which may depend on the C compiler and linker used). + + +

+This function is not supported by ANSI C. +As such, it is only available on some platforms +(Windows, Linux, Mac OS X, Solaris, BSD, +plus other Unix systems that support the dlfcn standard). + + + + +

+

package.path

+ + +

+The path used by require to search for a Lua loader. + + +

+At start-up, Lua initializes this variable with +the value of the environment variable LUA_PATH or +with a default path defined in luaconf.h, +if the environment variable is not defined. +Any ";;" in the value of the environment variable +is replaced by the default path. + + + + +

+

package.preload

+ + +

+A table to store loaders for specific modules +(see require). + + + + +

+

package.seeall (module)

+ + +

+Sets a metatable for module with +its __index field referring to the global environment, +so that this module inherits values +from the global environment. +To be used as an option to function module. + + + + + + + +

5.4 - String Manipulation

+ +

+This library provides generic functions for string manipulation, +such as finding and extracting substrings, and pattern matching. +When indexing a string in Lua, the first character is at position 1 +(not at 0, as in C). +Indices are allowed to be negative and are interpreted as indexing backwards, +from the end of the string. +Thus, the last character is at position -1, and so on. + + +

+The string library provides all its functions inside the table +string. +It also sets a metatable for strings +where the __index field points to the string table. +Therefore, you can use the string functions in object-oriented style. +For instance, string.byte(s, i) +can be written as s:byte(i). + + +

+The string library assumes one-byte character encodings. + + +

+

string.byte (s [, i [, j]])

+Returns the internal numerical codes of the characters s[i], +s[i+1], ···, s[j]. +The default value for i is 1; +the default value for j is i. + + +

+Note that numerical codes are not necessarily portable across platforms. + + + + +

+

string.char (···)

+Receives zero or more integers. +Returns a string with length equal to the number of arguments, +in which each character has the internal numerical code equal +to its corresponding argument. + + +

+Note that numerical codes are not necessarily portable across platforms. + + + + +

+

string.dump (function)

+ + +

+Returns a string containing a binary representation of the given function, +so that a later loadstring on this string returns +a copy of the function. +function must be a Lua function without upvalues. + + + + +

+

string.find (s, pattern [, init [, plain]])

+Looks for the first match of +pattern in the string s. +If it finds a match, then find returns the indices of s +where this occurrence starts and ends; +otherwise, it returns nil. +A third, optional numerical argument init specifies +where to start the search; +its default value is 1 and can be negative. +A value of true as a fourth, optional argument plain +turns off the pattern matching facilities, +so the function does a plain "find substring" operation, +with no characters in pattern being considered "magic". +Note that if plain is given, then init must be given as well. + + +

+If the pattern has captures, +then in a successful match +the captured values are also returned, +after the two indices. + + + + +

+

string.format (formatstring, ···)

+Returns a formatted version of its variable number of arguments +following the description given in its first argument (which must be a string). +The format string follows the same rules as the printf family of +standard C functions. +The only differences are that the options/modifiers +*, l, L, n, p, +and h are not supported +and that there is an extra option, q. +The q option formats a string in a form suitable to be safely read +back by the Lua interpreter: +the string is written between double quotes, +and all double quotes, newlines, embedded zeros, +and backslashes in the string +are correctly escaped when written. +For instance, the call + +
+     string.format('%q', 'a string with "quotes" and \n new line')
+

+will produce the string: + +

+     "a string with \"quotes\" and \
+      new line"
+
+ +

+The options c, d, E, e, f, +g, G, i, o, u, X, and x all +expect a number as argument, +whereas q and s expect a string. + + +

+This function does not accept string values +containing embedded zeros, +except as arguments to the q option. + + + + +

+

string.gmatch (s, pattern)

+Returns an iterator function that, +each time it is called, +returns the next captures from pattern over string s. +If pattern specifies no captures, +then the whole match is produced in each call. + + +

+As an example, the following loop + +

+     s = "hello world from Lua"
+     for w in string.gmatch(s, "%a+") do
+       print(w)
+     end
+

+will iterate over all the words from string s, +printing one per line. +The next example collects all pairs key=value from the +given string into a table: + +

+     t = {}
+     s = "from=world, to=Lua"
+     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
+       t[k] = v
+     end
+
+ +

+For this function, a '^' at the start of a pattern does not +work as an anchor, as this would prevent the iteration. + + + + +

+

string.gsub (s, pattern, repl [, n])

+Returns a copy of s +in which all (or the first n, if given) +occurrences of the pattern have been +replaced by a replacement string specified by repl, +which can be a string, a table, or a function. +gsub also returns, as its second value, +the total number of matches that occurred. + + +

+If repl is a string, then its value is used for replacement. +The character % works as an escape character: +any sequence in repl of the form %n, +with n between 1 and 9, +stands for the value of the n-th captured substring (see below). +The sequence %0 stands for the whole match. +The sequence %% stands for a single %. + + +

+If repl is a table, then the table is queried for every match, +using the first capture as the key; +if the pattern specifies no captures, +then the whole match is used as the key. + + +

+If repl is a function, then this function is called every time a +match occurs, with all captured substrings passed as arguments, +in order; +if the pattern specifies no captures, +then the whole match is passed as a sole argument. + + +

+If the value returned by the table query or by the function call +is a string or a number, +then it is used as the replacement string; +otherwise, if it is false or nil, +then there is no replacement +(that is, the original match is kept in the string). + + +

+Here are some examples: + +

+     x = string.gsub("hello world", "(%w+)", "%1 %1")
+     --> x="hello hello world world"
+     
+     x = string.gsub("hello world", "%w+", "%0 %0", 1)
+     --> x="hello hello world"
+     
+     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
+     --> x="world hello Lua from"
+     
+     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
+     --> x="home = /home/roberto, user = roberto"
+     
+     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
+           return loadstring(s)()
+         end)
+     --> x="4+5 = 9"
+     
+     local t = {name="lua", version="5.1"}
+     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
+     --> x="lua-5.1.tar.gz"
+
+ + + +

+

string.len (s)

+Receives a string and returns its length. +The empty string "" has length 0. +Embedded zeros are counted, +so "a\000bc\000" has length 5. + + + + +

+

string.lower (s)

+Receives a string and returns a copy of this string with all +uppercase letters changed to lowercase. +All other characters are left unchanged. +The definition of what an uppercase letter is depends on the current locale. + + + + +

+

string.match (s, pattern [, init])

+Looks for the first match of +pattern in the string s. +If it finds one, then match returns +the captures from the pattern; +otherwise it returns nil. +If pattern specifies no captures, +then the whole match is returned. +A third, optional numerical argument init specifies +where to start the search; +its default value is 1 and can be negative. + + + + +

+

string.rep (s, n)

+Returns a string that is the concatenation of n copies of +the string s. + + + + +

+

string.reverse (s)

+Returns a string that is the string s reversed. + + + + +

+

string.sub (s, i [, j])

+Returns the substring of s that +starts at i and continues until j; +i and j can be negative. +If j is absent, then it is assumed to be equal to -1 +(which is the same as the string length). +In particular, +the call string.sub(s,1,j) returns a prefix of s +with length j, +and string.sub(s, -i) returns a suffix of s +with length i. + + + + +

+

string.upper (s)

+Receives a string and returns a copy of this string with all +lowercase letters changed to uppercase. +All other characters are left unchanged. +The definition of what a lowercase letter is depends on the current locale. + + + +

5.4.1 - Patterns

+ + +

Character Class:

+A character class is used to represent a set of characters. +The following combinations are allowed in describing a character class: + +

    + +
  • x: +(where x is not one of the magic characters +^$()%.[]*+-?) +represents the character x itself. +
    • + +
  • .: (a dot) represents all characters.
    • + +
  • %a: represents all letters.
    • + +
  • %c: represents all control characters.
    • + +
  • %d: represents all digits.
    • + +
  • %l: represents all lowercase letters.
    • + +
  • %p: represents all punctuation characters.
    • + +
  • %s: represents all space characters.
    • + +
  • %u: represents all uppercase letters.
    • + +
  • %w: represents all alphanumeric characters.
    • + +
  • %x: represents all hexadecimal digits.
    • + +
  • %z: represents the character with representation 0.
    • + +
  • %x: (where x is any non-alphanumeric character) +represents the character x. +This is the standard way to escape the magic characters. +Any punctuation character (even the non magic) +can be preceded by a '%' +when used to represent itself in a pattern. +
    • + +
  • [set]: +represents the class which is the union of all +characters in set. +A range of characters can be specified by +separating the end characters of the range with a '-'. +All classes %x described above can also be used as +components in set. +All other characters in set represent themselves. +For example, [%w_] (or [_%w]) +represents all alphanumeric characters plus the underscore, +[0-7] represents the octal digits, +and [0-7%l%-] represents the octal digits plus +the lowercase letters plus the '-' character. + + +

    +The interaction between ranges and classes is not defined. +Therefore, patterns like [%a-z] or [a-%%] +have no meaning. +

    • + +
  • [^set]: +represents the complement of set, +where set is interpreted as above. +
    • + +

+For all classes represented by single letters (%a, %c, etc.), +the corresponding uppercase letter represents the complement of the class. +For instance, %S represents all non-space characters. + + +

+The definitions of letter, space, and other character groups +depend on the current locale. +In particular, the class [a-z] may not be equivalent to %l. + + + + + +

Pattern Item:

+A pattern item can be + +

    + +
  • +a single character class, +which matches any single character in the class; +
    • + +
  • +a single character class followed by '*', +which matches 0 or more repetitions of characters in the class. +These repetition items will always match the longest possible sequence; +
    • + +
  • +a single character class followed by '+', +which matches 1 or more repetitions of characters in the class. +These repetition items will always match the longest possible sequence; +
    • + +
  • +a single character class followed by '-', +which also matches 0 or more repetitions of characters in the class. +Unlike '*', +these repetition items will always match the shortest possible sequence; +
    • + +
  • +a single character class followed by '?', +which matches 0 or 1 occurrence of a character in the class; +
    • + +
  • +%n, for n between 1 and 9; +such item matches a substring equal to the n-th captured string +(see below); +
    • + +
  • +%bxy, where x and y are two distinct characters; +such item matches strings that start with x, end with y, +and where the x and y are balanced. +This means that, if one reads the string from left to right, +counting +1 for an x and -1 for a y, +the ending y is the first y where the count reaches 0. +For instance, the item %b() matches expressions with +balanced parentheses. +
    • + +
+ + + + +

Pattern:

+A pattern is a sequence of pattern items. +A '^' at the beginning of a pattern anchors the match at the +beginning of the subject string. +A '$' at the end of a pattern anchors the match at the +end of the subject string. +At other positions, +'^' and '$' have no special meaning and represent themselves. + + + + + +

Captures:

+A pattern can contain sub-patterns enclosed in parentheses; +they describe captures. +When a match succeeds, the substrings of the subject string +that match captures are stored (captured) for future use. +Captures are numbered according to their left parentheses. +For instance, in the pattern "(a*(.)%w(%s*))", +the part of the string matching "a*(.)%w(%s*)" is +stored as the first capture (and therefore has number 1); +the character matching "." is captured with number 2, +and the part matching "%s*" has number 3. + + +

+As a special case, the empty capture () captures +the current string position (a number). +For instance, if we apply the pattern "()aa()" on the +string "flaaap", there will be two captures: 3 and 5. + + +

+A pattern cannot contain embedded zeros. Use %z instead. + + + + + + + + + + + +

5.5 - Table Manipulation

+This library provides generic functions for table manipulation. +It provides all its functions inside the table table. + + +

+Most functions in the table library assume that the table +represents an array or a list. +For these functions, when we talk about the "length" of a table +we mean the result of the length operator. + + +

+

table.concat (table [, sep [, i [, j]]])

+Given an array where all elements are strings or numbers, +returns table[i]..sep..table[i+1] ··· sep..table[j]. +The default value for sep is the empty string, +the default for i is 1, +and the default for j is the length of the table. +If i is greater than j, returns the empty string. + + + + +

+

table.insert (table, [pos,] value)

+ + +

+Inserts element value at position pos in table, +shifting up other elements to open space, if necessary. +The default value for pos is n+1, +where n is the length of the table (see §2.5.5), +so that a call table.insert(t,x) inserts x at the end +of table t. + + + + +

+

table.maxn (table)

+ + +

+Returns the largest positive numerical index of the given table, +or zero if the table has no positive numerical indices. +(To do its job this function does a linear traversal of +the whole table.) + + + + +

+

table.remove (table [, pos])

+ + +

+Removes from table the element at position pos, +shifting down other elements to close the space, if necessary. +Returns the value of the removed element. +The default value for pos is n, +where n is the length of the table, +so that a call table.remove(t) removes the last element +of table t. + + + + +

+

table.sort (table [, comp])

+Sorts table elements in a given order, in-place, +from table[1] to table[n], +where n is the length of the table. +If comp is given, +then it must be a function that receives two table elements, +and returns true +when the first is less than the second +(so that not comp(a[i+1],a[i]) will be true after the sort). +If comp is not given, +then the standard Lua operator < is used instead. + + +

+The sort algorithm is not stable; +that is, elements considered equal by the given order +may have their relative positions changed by the sort. + + + + + + + +

5.6 - Mathematical Functions

+ +

5.7 - Input and Output Facilities

+ +

+The I/O library provides two different styles for file manipulation. +The first one uses implicit file descriptors; +that is, there are operations to set a default input file and a +default output file, +and all input/output operations are over these default files. +The second style uses explicit file descriptors. + + +

+When using implicit file descriptors, +all operations are supplied by table io. +When using explicit file descriptors, +the operation io.open returns a file descriptor +and then all operations are supplied as methods of the file descriptor. + + +

+The table io also provides +three predefined file descriptors with their usual meanings from C: +io.stdin, io.stdout, and io.stderr. +The I/O library never closes these files. + + +

+Unless otherwise stated, +all I/O functions return nil on failure +(plus an error message as a second result and +a system-dependent error code as a third result) +and some value different from nil on success. + + +

+

io.close ([file])

+ + +

+Equivalent to file:close(). +Without a file, closes the default output file. + + + + +

+

io.flush ()

+ + +

+Equivalent to file:flush over the default output file. + + + + +

+

io.input ([file])

+ + +

+When called with a file name, it opens the named file (in text mode), +and sets its handle as the default input file. +When called with a file handle, +it simply sets this file handle as the default input file. +When called without parameters, +it returns the current default input file. + + +

+In case of errors this function raises the error, +instead of returning an error code. + + + + +

+

io.lines ([filename])

+ + +

+Opens the given file name in read mode +and returns an iterator function that, +each time it is called, +returns a new line from the file. +Therefore, the construction + +

+     for line in io.lines(filename) do body end
+

+will iterate over all lines of the file. +When the iterator function detects the end of file, +it returns nil (to finish the loop) and automatically closes the file. + + +

+The call io.lines() (with no file name) is equivalent +to io.input():lines(); +that is, it iterates over the lines of the default input file. +In this case it does not close the file when the loop ends. + + + + +

+

io.open (filename [, mode])

+ + +

+This function opens a file, +in the mode specified in the string mode. +It returns a new file handle, +or, in case of errors, nil plus an error message. + + +

+The mode string can be any of the following: + +

    +
  • "r": read mode (the default);
    • +
  • "w": write mode;
    • +
  • "a": append mode;
    • +
  • "r+": update mode, all previous data is preserved;
    • +
  • "w+": update mode, all previous data is erased;
    • +
  • "a+": append update mode, previous data is preserved, + writing is only allowed at the end of file.
    • +

+The mode string can also have a 'b' at the end, +which is needed in some systems to open the file in binary mode. +This string is exactly what is used in the +standard C function fopen. + + + + +

+

io.output ([file])

+ + +

+Similar to io.input, but operates over the default output file. + + + + +

+

io.popen (prog [, mode])

+ + +

+Starts program prog in a separated process and returns +a file handle that you can use to read data from this program +(if mode is "r", the default) +or to write data to this program +(if mode is "w"). + + +

+This function is system dependent and is not available +on all platforms. + + + + +

+

io.read (···)

+ + +

+Equivalent to io.input():read. + + + + +

+

io.tmpfile ()

+ + +

+Returns a handle for a temporary file. +This file is opened in update mode +and it is automatically removed when the program ends. + + + + +

+

io.type (obj)

+ + +

+Checks whether obj is a valid file handle. +Returns the string "file" if obj is an open file handle, +"closed file" if obj is a closed file handle, +or nil if obj is not a file handle. + + + + +

+

io.write (···)

+ + +

+Equivalent to io.output():write. + + + + +

+

file:close ()

+ + +

+Closes file. +Note that files are automatically closed when +their handles are garbage collected, +but that takes an unpredictable amount of time to happen. + + + + +

+

file:flush ()

+ + +

+Saves any written data to file. + + + + +

+

file:lines ()

+ + +

+Returns an iterator function that, +each time it is called, +returns a new line from the file. +Therefore, the construction + +

+     for line in file:lines() do body end
+

+will iterate over all lines of the file. +(Unlike io.lines, this function does not close the file +when the loop ends.) + + + + +

+

file:read (···)

+ + +

+Reads the file file, +according to the given formats, which specify what to read. +For each format, +the function returns a string (or a number) with the characters read, +or nil if it cannot read data with the specified format. +When called without formats, +it uses a default format that reads the entire next line +(see below). + + +

+The available formats are + +

    + +
  • "*n": +reads a number; +this is the only format that returns a number instead of a string. +
    • + +
  • "*a": +reads the whole file, starting at the current position. +On end of file, it returns the empty string. +
    • + +
  • "*l": +reads the next line (skipping the end of line), +returning nil on end of file. +This is the default format. +
    • + +
  • number: +reads a string with up to this number of characters, +returning nil on end of file. +If number is zero, +it reads nothing and returns an empty string, +or nil on end of file. +
    • + +
+ + + +

+

file:seek ([whence] [, offset])

+ + +

+Sets and gets the file position, +measured from the beginning of the file, +to the position given by offset plus a base +specified by the string whence, as follows: + +

    +
  • "set": base is position 0 (beginning of the file);
    • +
  • "cur": base is current position;
    • +
  • "end": base is end of file;
    • +

+In case of success, function seek returns the final file position, +measured in bytes from the beginning of the file. +If this function fails, it returns nil, +plus a string describing the error. + + +

+The default value for whence is "cur", +and for offset is 0. +Therefore, the call file:seek() returns the current +file position, without changing it; +the call file:seek("set") sets the position to the +beginning of the file (and returns 0); +and the call file:seek("end") sets the position to the +end of the file, and returns its size. + + + + +

+

file:setvbuf (mode [, size])

+ + +

+Sets the buffering mode for an output file. +There are three available modes: + +

    + +
  • "no": +no buffering; the result of any output operation appears immediately. +
    • + +
  • "full": +full buffering; output operation is performed only +when the buffer is full (or when you explicitly flush the file +(see io.flush)). +
    • + +
  • "line": +line buffering; output is buffered until a newline is output +or there is any input from some special files +(such as a terminal device). +
    • + +

+For the last two cases, size +specifies the size of the buffer, in bytes. +The default is an appropriate size. + + + + +

+

file:write (···)

+ + +

+Writes the value of each of its arguments to +the file. +The arguments must be strings or numbers. +To write other values, +use tostring or string.format before write. + + + + + + + +

5.8 - Operating System Facilities

+ +

+This library is implemented through table os. + + +

+

os.clock ()

+ + +

+Returns an approximation of the amount in seconds of CPU time +used by the program. + + + + +

+

os.date ([format [, time]])

+ + +

+Returns a string or a table containing date and time, +formatted according to the given string format. + + +

+If the time argument is present, +this is the time to be formatted +(see the os.time function for a description of this value). +Otherwise, date formats the current time. + + +

+If format starts with '!', +then the date is formatted in Coordinated Universal Time. +After this optional character, +if format is the string "*t", +then date returns a table with the following fields: +year (four digits), month (1--12), day (1--31), +hour (0--23), min (0--59), sec (0--61), +wday (weekday, Sunday is 1), +yday (day of the year), +and isdst (daylight saving flag, a boolean). + + +

+If format is not "*t", +then date returns the date as a string, +formatted according to the same rules as the C function strftime. + + +

+When called without arguments, +date returns a reasonable date and time representation that depends on +the host system and on the current locale +(that is, os.date() is equivalent to os.date("%c")). + + + + +

+

os.difftime (t2, t1)

+ + +

+Returns the number of seconds from time t1 to time t2. +In POSIX, Windows, and some other systems, +this value is exactly t2-t1. + + + + +

+

os.execute ([command])

+ + +

+This function is equivalent to the C function system. +It passes command to be executed by an operating system shell. +It returns a status code, which is system-dependent. +If command is absent, then it returns nonzero if a shell is available +and zero otherwise. + + + + +

+

os.exit ([code])

+ + +

+Calls the C function exit, +with an optional code, +to terminate the host program. +The default value for code is the success code. + + + + +

+

os.getenv (varname)

+ + +

+Returns the value of the process environment variable varname, +or nil if the variable is not defined. + + + + +

+

os.remove (filename)

+ + +

+Deletes the file or directory with the given name. +Directories must be empty to be removed. +If this function fails, it returns nil, +plus a string describing the error. + + + + +

+

os.rename (oldname, newname)

+ + +

+Renames file or directory named oldname to newname. +If this function fails, it returns nil, +plus a string describing the error. + + + + +

+

os.setlocale (locale [, category])

+ + +

+Sets the current locale of the program. +locale is a string specifying a locale; +category is an optional string describing which category to change: +"all", "collate", "ctype", +"monetary", "numeric", or "time"; +the default category is "all". +The function returns the name of the new locale, +or nil if the request cannot be honored. + + +

+If locale is the empty string, +the current locale is set to an implementation-defined native locale. +If locale is the string "C", +the current locale is set to the standard C locale. + + +

+When called with nil as the first argument, +this function only returns the name of the current locale +for the given category. + + + + +

+

os.time ([table])

+ + +

+Returns the current time when called without arguments, +or a time representing the date and time specified by the given table. +This table must have fields year, month, and day, +and may have fields hour, min, sec, and isdst +(for a description of these fields, see the os.date function). + + +

+The returned value is a number, whose meaning depends on your system. +In POSIX, Windows, and some other systems, this number counts the number +of seconds since some given start time (the "epoch"). +In other systems, the meaning is not specified, +and the number returned by time can be used only as an argument to +date and difftime. + + + + +

+

os.tmpname ()

+ + +

+Returns a string with a file name that can +be used for a temporary file. +The file must be explicitly opened before its use +and explicitly removed when no longer needed. + + +

+On some systems (POSIX), +this function also creates a file with that name, +to avoid security risks. +(Someone else might create the file with wrong permissions +in the time between getting the name and creating the file.) +You still have to open the file to use it +and to remove it (even if you do not use it). + + +

+When possible, +you may prefer to use io.tmpfile, +which automatically removes the file when the program ends. + + + + + + + +

5.9 - The Debug Library

+ +

+This library provides +the functionality of the debug interface to Lua programs. +You should exert care when using this library. +The functions provided here should be used exclusively for debugging +and similar tasks, such as profiling. +Please resist the temptation to use them as a +usual programming tool: +they can be very slow. +Moreover, several of these functions +violate some assumptions about Lua code +(e.g., that variables local to a function +cannot be accessed from outside or +that userdata metatables cannot be changed by Lua code) +and therefore can compromise otherwise secure code. + + +

+All functions in this library are provided +inside the debug table. +All functions that operate over a thread +have an optional first argument which is the +thread to operate over. +The default is always the current thread. + + +

+

debug.debug ()

+ + +

+Enters an interactive mode with the user, +running each string that the user enters. +Using simple commands and other debug facilities, +the user can inspect global and local variables, +change their values, evaluate expressions, and so on. +A line containing only the word cont finishes this function, +so that the caller continues its execution. + + +

+Note that commands for debug.debug are not lexically nested +within any function, and so have no direct access to local variables. + + + + +

+

debug.getfenv (o)

+Returns the environment of object o. + + + + +

+

debug.gethook ([thread])

+ + +

+Returns the current hook settings of the thread, as three values: +the current hook function, the current hook mask, +and the current hook count +(as set by the debug.sethook function). + + + + +

+

debug.getinfo ([thread,] function [, what])

+ + +

+Returns a table with information about a function. +You can give the function directly, +or you can give a number as the value of function, +which means the function running at level function of the call stack +of the given thread: +level 0 is the current function (getinfo itself); +level 1 is the function that called getinfo; +and so on. +If function is a number larger than the number of active functions, +then getinfo returns nil. + + +

+The returned table can contain all the fields returned by lua_getinfo, +with the string what describing which fields to fill in. +The default for what is to get all information available, +except the table of valid lines. +If present, +the option 'f' +adds a field named func with the function itself. +If present, +the option 'L' +adds a field named activelines with the table of +valid lines. + + +

+For instance, the expression debug.getinfo(1,"n").name returns +a table with a name for the current function, +if a reasonable name can be found, +and the expression debug.getinfo(print) +returns a table with all available information +about the print function. + + + + +

+

debug.getlocal ([thread,] level, local)

+ + +

+This function returns the name and the value of the local variable +with index local of the function at level level of the stack. +(The first parameter or local variable has index 1, and so on, +until the last active local variable.) +The function returns nil if there is no local +variable with the given index, +and raises an error when called with a level out of range. +(You can call debug.getinfo to check whether the level is valid.) + + +

+Variable names starting with '(' (open parentheses) +represent internal variables +(loop control variables, temporaries, and C function locals). + + + + +

+

debug.getmetatable (object)

+ + +

+Returns the metatable of the given object +or nil if it does not have a metatable. + + + + +

+

debug.getregistry ()

+ + +

+Returns the registry table (see §3.5). + + + + +

+

debug.getupvalue (func, up)

+ + +

+This function returns the name and the value of the upvalue +with index up of the function func. +The function returns nil if there is no upvalue with the given index. + + + + +

+

debug.setfenv (object, table)

+ + +

+Sets the environment of the given object to the given table. +Returns object. + + + + +

+

debug.sethook ([thread,] hook, mask [, count])

+ + +

+Sets the given function as a hook. +The string mask and the number count describe +when the hook will be called. +The string mask may have the following characters, +with the given meaning: + +

    +
  • "c": the hook is called every time Lua calls a function;
    • +
  • "r": the hook is called every time Lua returns from a function;
    • +
  • "l": the hook is called every time Lua enters a new line of code.
    • +

+With a count different from zero, +the hook is called after every count instructions. + + +

+When called without arguments, +debug.sethook turns off the hook. + + +

+When the hook is called, its first parameter is a string +describing the event that has triggered its call: +"call", "return" (or "tail return", +when simulating a return from a tail call), +"line", and "count". +For line events, +the hook also gets the new line number as its second parameter. +Inside a hook, +you can call getinfo with level 2 to get more information about +the running function +(level 0 is the getinfo function, +and level 1 is the hook function), +unless the event is "tail return". +In this case, Lua is only simulating the return, +and a call to getinfo will return invalid data. + + + + +

+

debug.setlocal ([thread,] level, local, value)

+ + +

+This function assigns the value value to the local variable +with index local of the function at level level of the stack. +The function returns nil if there is no local +variable with the given index, +and raises an error when called with a level out of range. +(You can call getinfo to check whether the level is valid.) +Otherwise, it returns the name of the local variable. + + + + +

+

debug.setmetatable (object, table)

+ + +

+Sets the metatable for the given object to the given table +(which can be nil). + + + + +

+

debug.setupvalue (func, up, value)

+ + +

+This function assigns the value value to the upvalue +with index up of the function func. +The function returns nil if there is no upvalue +with the given index. +Otherwise, it returns the name of the upvalue. + + + + +

+

debug.traceback ([thread,] [message [, level]])

+ + +

+Returns a string with a traceback of the call stack. +An optional message string is appended +at the beginning of the traceback. +An optional level number tells at which level +to start the traceback +(default is 1, the function calling traceback). + + + + + + + +

6 - Lua Stand-alone

+ +

+Although Lua has been designed as an extension language, +to be embedded in a host C program, +it is also frequently used as a stand-alone language. +An interpreter for Lua as a stand-alone language, +called simply lua, +is provided with the standard distribution. +The stand-alone interpreter includes +all standard libraries, including the debug library. +Its usage is: + +

+     lua [options] [script [args]]
+

+The options are: + +

    +
  • -e stat: executes string stat;
    • +
  • -l mod: "requires" mod;
    • +
  • -i: enters interactive mode after running script;
    • +
  • -v: prints version information;
    • +
  • --: stops handling options;
    • +
  • -: executes stdin as a file and stops handling options.
    • +

+After handling its options, lua runs the given script, +passing to it the given args as string arguments. +When called without arguments, +lua behaves as lua -v -i +when the standard input (stdin) is a terminal, +and as lua - otherwise. + + +

+Before running any argument, +the interpreter checks for an environment variable LUA_INIT. +If its format is @filename, +then lua executes the file. +Otherwise, lua executes the string itself. + + +

+All options are handled in order, except -i. +For instance, an invocation like + +

+     $ lua -e'a=1' -e 'print(a)' script.lua
+

+will first set a to 1, then print the value of a (which is '1'), +and finally run the file script.lua with no arguments. +(Here $ is the shell prompt. Your prompt may be different.) + + +

+Before starting to run the script, +lua collects all arguments in the command line +in a global table called arg. +The script name is stored at index 0, +the first argument after the script name goes to index 1, +and so on. +Any arguments before the script name +(that is, the interpreter name plus the options) +go to negative indices. +For instance, in the call + +

+     $ lua -la b.lua t1 t2
+

+the interpreter first runs the file a.lua, +then creates a table + +

+     arg = { [-2] = "lua", [-1] = "-la",
+             [0] = "b.lua",
+             [1] = "t1", [2] = "t2" }
+

+and finally runs the file b.lua. +The script is called with arg[1], arg[2], ··· +as arguments; +it can also access these arguments with the vararg expression '...'. + + +

+In interactive mode, +if you write an incomplete statement, +the interpreter waits for its completion +by issuing a different prompt. + + +

+If the global variable _PROMPT contains a string, +then its value is used as the prompt. +Similarly, if the global variable _PROMPT2 contains a string, +its value is used as the secondary prompt +(issued during incomplete statements). +Therefore, both prompts can be changed directly on the command line +or in any Lua programs by assigning to _PROMPT. +See the next example: + +

+     $ lua -e"_PROMPT='myprompt> '" -i
+

+(The outer pair of quotes is for the shell, +the inner pair is for Lua.) +Note the use of -i to enter interactive mode; +otherwise, +the program would just end silently +right after the assignment to _PROMPT. + + +

+To allow the use of Lua as a +script interpreter in Unix systems, +the stand-alone interpreter skips +the first line of a chunk if it starts with #. +Therefore, Lua scripts can be made into executable programs +by using chmod +x and the #! form, +as in + +

+     #!/usr/local/bin/lua
+

+(Of course, +the location of the Lua interpreter may be different in your machine. +If lua is in your PATH, +then + +

+     #!/usr/bin/env lua
+

+is a more portable solution.) + + + +

7 - Incompatibilities with the Previous Version

+ +

+Here we list the incompatibilities that you may find when moving a program +from Lua 5.0 to Lua 5.1. +You can avoid most of the incompatibilities compiling Lua with +appropriate options (see file luaconf.h). +However, +all these compatibility options will be removed in the next version of Lua. + + + +

7.1 - Changes in the Language

+
    + +
  • +The vararg system changed from the pseudo-argument arg with a +table with the extra arguments to the vararg expression. +(See compile-time option LUA_COMPAT_VARARG in luaconf.h.) +
    • + +
  • +There was a subtle change in the scope of the implicit +variables of the for statement and for the repeat statement. +
    • + +
  • +The long string/long comment syntax ([[string]]) +does not allow nesting. +You can use the new syntax ([=[string]=]) in these cases. +(See compile-time option LUA_COMPAT_LSTR in luaconf.h.) +
    • + +
+ + + + +

7.2 - Changes in the Libraries

+
    + +
  • +Function string.gfind was renamed string.gmatch. +(See compile-time option LUA_COMPAT_GFIND in luaconf.h.) +
    • + +
  • +When string.gsub is called with a function as its +third argument, +whenever this function returns nil or false the +replacement string is the whole match, +instead of the empty string. +
    • + +
  • +Function table.setn was deprecated. +Function table.getn corresponds +to the new length operator (#); +use the operator instead of the function. +(See compile-time option LUA_COMPAT_GETN in luaconf.h.) +
    • + +
  • +Function loadlib was renamed package.loadlib. +(See compile-time option LUA_COMPAT_LOADLIB in luaconf.h.) +
    • + +
  • +Function math.mod was renamed math.fmod. +(See compile-time option LUA_COMPAT_MOD in luaconf.h.) +
    • + +
  • +Functions table.foreach and table.foreachi are deprecated. +You can use a for loop with pairs or ipairs instead. +
    • + +
  • +There were substantial changes in function require due to +the new module system. +However, the new behavior is mostly compatible with the old, +but require gets the path from package.path instead +of from LUA_PATH. +
    • + +
  • +Function collectgarbage has different arguments. +Function gcinfo is deprecated; +use collectgarbage("count") instead. +
    • + +
+ + + + +

7.3 - Changes in the API

+
    + +
  • +The luaopen_* functions (to open libraries) +cannot be called directly, +like a regular C function. +They must be called through Lua, +like a Lua function. +
    • + +
  • +Function lua_open was replaced by lua_newstate to +allow the user to set a memory-allocation function. +You can use luaL_newstate from the standard library to +create a state with a standard allocation function +(based on realloc). +
    • + +
  • +Functions luaL_getn and luaL_setn +(from the auxiliary library) are deprecated. +Use lua_objlen instead of luaL_getn +and nothing instead of luaL_setn. +
    • + +
  • +Function luaL_openlib was replaced by luaL_register. +
    • + +
  • +Function luaL_checkudata now throws an error when the given value +is not a userdata of the expected type. +(In Lua 5.0 it returned NULL.) +
    • + +
+ + + + +
