The configuration +options provided by `configure` or `cmake` should be enough. In particular, +if you just want HarfBuzz library plus hb-shape / hb-view utilities, make sure +FreeType and Cairo are available and found during configuration. + +If you are building for distribution, you should more carefully consider whether +you need Glib, ICU, Graphite2, as well as CoreText / Uniscribe / DWrite. Make +sure the relevant ones are enabled. + +If you are building for custom environment (embedded, downloadable app, etc) +where you mostly just want to call `hb_shape()` and the binary size of the +resulting library is very important to you, the rest of this file guides you +through your options to disable features you may not need, in exchange for +binary size savings. + +## Compiler Options + +Make sure you build with your compiler's "optimize for size" option. On `gcc` +this is `-Os`, and can be enabled by passing `CXXFLAGS=-Os` either to `configure` +(sticky) or to `make` (non-sticky). On clang there is an even more extreme flag, +`-Oz`. + +HarfBuzz heavily uses inline functions and the optimize-size flag can make the +library smaller by 20% or more. Moreover, sometimes, based on the target CPU, +the optimize-size builds perform *faster* as well, thanks to lower code +footprint and caching effects. So, definitely try that even if size is not +extremely tight but you have a huge application. For example, Chrome does +that. Note that this configuration also automatically enables certain internal +optimizations. Search for `HB_OPTIMIZE_SIZE` for details, if you are using +other compilers, or continue reading. + +Another compiler option to consider is "link-time optimization", also known as +'lto'. To enable that, with `gcc` or `clang`, add `-flto` to both `CXXFLAGS` +and `LDFLAGS`, either on `configure` invocation (sticky) or on `make` (non-sticky). +This, also, can have a huge impact on the final size, 20% or more. + +Finally, if you are making a static library build or otherwise linking the +library into your app, make sure your linker removes unused functions. This +can be tricky and differ from environment to environment, but you definitely +want to make sure this happens. Otherwise, every unused public function will +be adding unneeded bytes to your binary. The following pointers might come +handy: + + * https://lwn.net/Articles/741494/ (all of the four-part series) + * https://elinux.org/images/2/2d/ELC2010-gc-sections_Denys_Vlasenko.pdf + +Combining the above three build options should already shrink your library a lot. +The rest of this file shows you ways to shrink the library even further at the +expense of removing functionality (that may not be needed). The remaining +options are all enabled by defining pre-processor macros, which can be done +via `CXXFLAGS` or `CPPFLAGS` similarly. + + +## Unicode-functions + +Access to Unicode data can be configured at compile time as well as run-time. +By default, HarfBuzz ships with its own compact subset of properties from +Unicode Character Database that it needs. This is a highly-optimized +implementation that depending on compile settings (optimize-size or not) +takes around ~40kb or ~60kb. Using this implementation (default) is highly +recommended, as HarfBuzz always ships with data from latest version of Unicode. +This implementation can be disabled by defining `HB_NO_UCD`. + +For example, if you are enabling ICU as a built-in option, or GLib, those +can provide Unicode data as well, so defining `HB_NO_UCD` might save you +space without reducing functionality (to the extent that the Unicode version +of those implementations is recent.) + +If, however, you provide your own Unicode data to HarfBuzz at run-time by +calling `hb_buffer_set_unicode_funcs` on every buffer you create, and you do +not rely on `hb_unicode_funcs_get_default()` results, you can disable the +internal implementation by defining both `HB_NO_UCD` and `HB_NO_UNICODE_FUNCS`. +The latter is needed to guard against accidentally building a library without +any default Unicode implementations. + + +## Font-functions + +Access to certain font functionalities can also be configured at run-time. By +default, HarfBuzz uses an efficient internal implementation of OpenType +functionality for this. This internal implementation is called `hb-ot-font`. +All newly-created `hb_font_t` objects by default use `hb-ot-font`. Using this +is highly recommended, and is what fonts use by default when they are created. + +Most embedded uses will probably use HarfBuzz with FreeType using `hb-ft.h`. +In that case, or if you otherwise provide those functions by calling +`hb_font_set_funcs()` on every font you create, you can disable `hb-ot-font` +without loss of functionality by defining `HB_NO_OT_FONT`. + + +## Shapers + +Most HarfBuzz clients use it for the main shaper, called "ot". However, it +is legitimate to want to compile HarfBuzz with only another backend, eg. +CoreText, for example for an iOS app. For that, you want `HB_NO_OT_SHAPE`. +If you are going down that route, check if you want `HB_NO_OT`. + +This is very rarely what you need. Make sure you understand exactly what you +are doing. + +Defining `HB_NO_FALLBACK_SHAPE` however is pretty harmless. That removes the +(unused) "fallback" shaper. + + +## Thread-safety + +By default HarfBuzz builds as a thread-safe library. The exception is that +the `HB_TINY` predefined configuring (more below) disables thread-safety. + +If you do /not/ need thread-safety in the library (eg. you always call into +HarfBuzz from the same thread), you can disable thread-safety by defining +`HB_NO_MT`. As noted already, this is enabled by `HB_TINY`. + + +## Pre-defined configurations + +The [`hb-config.hh`](src/hb-config.hh) internal header supports three +pre-defined configurations as well grouping of various configuration options. +The pre-defined configurations are: + + * `HB_MINI`: Disables shaping of AAT as well as legacy fonts. Ie. it produces + a capable OpenType shaper only. + + * `HB_LEAN`: Disables various non-shaping functionality in the library, as well + as esoteric or rarely-used shaping features. See the definition for details. + + * `HB_TINY`: Enables both `HB_MINI` and `HB_LEAN` configurations, as well as + disabling thread-safety and debugging, and use even more size-optimized data + tables. + + +## Tailoring configuration + +Most of the time, one of the pre-defined configuration is exactly what one needs. +Sometimes, however, the pre-defined configuration cuts out features that might +be desired in the library. Unfortunately there is no quick way to undo those +configurations from the command-line. But one can add a header file called +`config-override.h` to undefine certain `HB_NO_*` symbols as desired. Then +define `HAVE_CONFIG_OVERRIDE_H` to make `hb-config.hh` include your configuration +overrides at the end. + + +## Notes + +Note that the config option `HB_NO_CFF`, which is enabled by `HB_LEAN` and +`HB_TINY` does /not/ mean that the resulting library won't work with CFF fonts. +The library can shape valid CFF fonts just fine, with or without this option. +This option disables (among other things) the code to calculate glyph exntents +for CFF fonts. diff --git a/singe/thirdparty/harfbuzz/COPYING b/singe/thirdparty/harfbuzz/COPYING new file mode 100644 index 000000000..0278e60a5 --- /dev/null +++ b/singe/thirdparty/harfbuzz/COPYING @@ -0,0 +1,37 @@ +HarfBuzz is licensed under the so-called "Old MIT" license.

HB_BUFFER_FLAG_BOT : 0) | + (item_offset + item_length == paragraph_length ? + HB_BUFFER_FLAG_EOT : 0)); + + hb_buffer_add_utf8 (hb_buffer, + paragraph_text, paragraph_length, + item_offset, item_length); + + After this change such clients can simply say: + + hb_buffer_set_flags (hb_buffer, + HB_BUFFER_FLAG_BOT | HB_BUFFER_FLAG_EOT); + + hb_buffer_add_utf8 (hb_buffer, + paragraph_text, paragraph_length, + item_offset, item_length); + + Ie, HarfBuzz itself checks whether the segment is at the beginning/end + of the paragraph. Clients that only pass item-at-a-time to HarfBuzz + continue not setting any flags whatsoever. + + Another way to put it is: if there's pre-context text in the buffer, + HarfBuzz ignores the BOT flag.

In this chapter, we'll look at how to set up a buffer with + the text that we want and how to customize the properties of the + buffer. We'll also look at a piece of lower-level machinery that + you will need to understand before proceeding: the functions that + HarfBuzz uses to retrieve Unicode information. + + + After shaping is complete, HarfBuzz puts its output back + into the buffer. But getting that output requires setting up a + face and a font first, so we will look at that in the next chapter + instead of here. + +
+ Creating and destroying buffers + + As we saw in our Getting Started example, a + buffer is created and + initialized with hb_buffer_create(). This + produces a new, empty buffer object, instantiated with some + default values and ready to accept your Unicode strings. + + + HarfBuzz manages the memory of objects (such as buffers) that it + creates, so you don't have to. When you have finished working on + a buffer, you can call hb_buffer_destroy(): + + + hb_buffer_t *buf = hb_buffer_create(); + ... + hb_buffer_destroy(buf); + + + This will destroy the object and free its associated memory - + unless some other part of the program holds a reference to this + buffer. If you acquire a HarfBuzz buffer from another subsystem + and want to ensure that it is not garbage collected by someone + else destroying it, you should increase its reference count: + + + void somefunc(hb_buffer_t *buf) { + buf = hb_buffer_reference(buf); + ... + + + And then decrease it once you're done with it: + + + hb_buffer_destroy(buf); + } + + + While we are on the subject of reference-counting buffers, it is + worth noting that an individual buffer can only meaningfully be + used by one thread at a time. + + + To throw away all the data in your buffer and start from scratch, + call hb_buffer_reset(buf). If you want to + throw away the string in the buffer but keep the options, you can + instead call hb_buffer_clear_contents(buf). + +
+ +
+ Adding text to the buffer + + Now we have a brand new HarfBuzz buffer. Let's start filling it + with text! From HarfBuzz's perspective, a buffer is just a stream + of Unicode code points, but your input string is probably in one of + the standard Unicode character encodings (UTF-8, UTF-16, or + UTF-32). HarfBuzz provides convenience functions that accept + each of these encodings: + hb_buffer_add_utf8(), + hb_buffer_add_utf16(), and + hb_buffer_add_utf32(). Other than the + character encoding they accept, they function identically. + + + You can add UTF-8 text to a buffer by passing in the text array, + the array's length, an offset into the array for the first + character to add, and the length of the segment to add: + + + hb_buffer_add_utf8 (hb_buffer_t *buf, + const char *text, + int text_length, + unsigned int item_offset, + int item_length) + + + So, in practice, you can say: + + + hb_buffer_add_utf8(buf, text, strlen(text), 0, strlen(text)); + + + This will append your new characters to + buf, not replace its existing + contents. Also, note that you can use -1 in + place of the first instance of strlen(text) + if your text array is NULL-terminated. Similarly, you can also use + -1 as the final argument want to add its full + contents. + + + Whatever start item_offset and + item_length you provide, HarfBuzz will also + attempt to grab the five characters before + the offset point and the five characters + after the designated end. These are the + before and after "context" segments, which are used internally + for HarfBuzz to make shaping decisions. They will not be part of + the final output, but they ensure that HarfBuzz's + script-specific shaping operations are correct. If there are + fewer than five characters available for the before or after + contexts, HarfBuzz will just grab what is there. + + + For longer text runs, such as full paragraphs, it might be + tempting to only add smaller sub-segments to a buffer and + shape them in piecemeal fashion. Generally, this is not a good + idea, however, because a lot of shaping decisions are + dependent on this context information. For example, in Arabic + and other connected scripts, HarfBuzz needs to know the code + points before and after each character in order to correctly + determine which glyph to return. + + + The safest approach is to add all of the text available, then + use item_offset and + item_length to indicate which characters you + want shaped, so that HarfBuzz has access to any context. + + + You can also add Unicode code points directly with + hb_buffer_add_codepoints(). The arguments + to this function are the same as those for the UTF + encodings. But it is particularly important to note that + HarfBuzz does not do validity checking on the text that is added + to a buffer. Invalid code points will be replaced, but it is up + to you to do any deep-sanity checking necessary. + + +
+ +
+ Setting buffer properties + + Buffers containing input characters still need several + properties set before HarfBuzz can shape their text correctly. + + + Initially, all buffers are set to the + HB_BUFFER_CONTENT_TYPE_INVALID content + type. After adding text, the buffer should be set to + HB_BUFFER_CONTENT_TYPE_UNICODE instead, which + indicates that it contains un-shaped input + characters. After shaping, the buffer will have the + HB_BUFFER_CONTENT_TYPE_GLYPHS content type. + + + hb_buffer_add_utf8() and the + other UTF functions set the content type of their buffer + automatically. But if you are reusing a buffer you may want to + check its state with + hb_buffer_get_content_type(buffer). If + necessary you can set the content type with + + + hb_buffer_set_content_type(buf, HB_BUFFER_CONTENT_TYPE_UNICODE); + + + to prepare for shaping. + + + Buffers also need to carry information about the script, + language, and text direction of their contents. You can set + these properties individually: + + + hb_buffer_set_direction(buf, HB_DIRECTION_LTR); + hb_buffer_set_script(buf, HB_SCRIPT_LATIN); + hb_buffer_set_language(buf, hb_language_from_string("en", -1)); + + + However, since these properties are often the repeated for + multiple text runs, you can also save them in a + hb_segment_properties_t for reuse: + + + hb_segment_properties_t *savedprops; + hb_buffer_get_segment_properties (buf, savedprops); + ... + hb_buffer_set_segment_properties (buf2, savedprops); + + + HarfBuzz also provides getter functions to retrieve a buffer's + direction, script, and language properties individually. + + + HarfBuzz recognizes four text directions in + hb_direction_t: left-to-right + (HB_DIRECTION_LTR), right-to-left (HB_DIRECTION_RTL), + top-to-bottom (HB_DIRECTION_TTB), and + bottom-to-top (HB_DIRECTION_BTT). For the + script property, HarfBuzz uses identifiers based on the + ISO 15924 + standard. For languages, HarfBuzz uses tags based on the + IETF BCP 47 standard. + + + Helper functions are provided to convert character strings into + the necessary script and language tag types. + + + Two additional buffer properties to be aware of are the + "invisible glyph" and the replacement code point. The + replacement code point is inserted into buffer output in place of + any invalid code points encountered in the input. By default, it + is the Unicode REPLACEMENT CHARACTER code + point, U+FFFD "�". You can change this with + + + hb_buffer_set_replacement_codepoint(buf, replacement); + + + passing in the replacement Unicode code point as the + replacement parameter. + + + The invisible glyph is used to replace all output glyphs that + are invisible. By default, the standard space character + U+0020 is used; you can replace this (for + example, when using a font that provides script-specific + spaces) with + + + hb_buffer_set_invisible_glyph(buf, replacement_glyph); + + + Do note that in the replacement_glyph + parameter, you must provide the glyph ID of the replacement you + wish to use, not the Unicode code point. + + + HarfBuzz supports a few additional flags you might want to set + on your buffer under certain circumstances. The + HB_BUFFER_FLAG_BOT and + HB_BUFFER_FLAG_EOT flags tell HarfBuzz + that the buffer represents the beginning or end (respectively) + of a text element (such as a paragraph or other block). Knowing + this allows HarfBuzz to apply certain contextual font features + when shaping, such as initial or final variants in connected + scripts. + + + HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES + tells HarfBuzz not to hide glyphs with the + Default_Ignorable property in Unicode. This + property designates control characters and other non-printing + code points, such as joiners and variation selectors. Normally + HarfBuzz replaces them in the output buffer with zero-width + space glyphs (using the "invisible glyph" property discussed + above); setting this flag causes them to be printed, which can + be helpful for troubleshooting. + + + Conversely, setting the + HB_BUFFER_FLAG_REMOVE_DEFAULT_IGNORABLES flag + tells HarfBuzz to remove Default_Ignorable + glyphs from the output buffer entirely. Finally, setting the + HB_BUFFER_FLAG_DO_NOT_INSERT_DOTTED_CIRCLE + flag tells HarfBuzz not to insert the dotted-circle glyph + (U+25CC, "◌"), which is normally + inserted into buffer output when broken character sequences are + encountered (such as combining marks that are not attached to a + base character). + +
+ +
+ Customizing Unicode functions + + HarfBuzz requires some simple functions for accessing + information from the Unicode Character Database (such as the + General_Category (gc) and + Script (sc) properties) that is useful + for shaping, as well as some useful operations like composing and + decomposing code points. + + + HarfBuzz includes its own internal, lightweight set of Unicode + functions. At build time, it is also possible to compile support + for some other options, such as the Unicode functions provided + by GLib or the International Components for Unicode (ICU) + library. Generally, this option is only of interest for client + programs that have specific integration requirements or that do + a significant amount of customization. + + + If your program has access to other Unicode functions, however, + such as through a system library or application framework, you + might prefer to use those instead of the built-in + options. HarfBuzz supports this by implementing its Unicode + functions as a set of virtual methods that you can replace — + without otherwise affecting HarfBuzz's functionality. + + + The Unicode functions are specified in a structure called + unicode_funcs which is attached to each + buffer. But even though unicode_funcs is + associated with a hb_buffer_t, the functions + themselves are called by other HarfBuzz APIs that access + buffers, so it would be unwise for you to hook different + functions into different buffers. + + + In addition, you can mark your unicode_funcs + as immutable by calling + hb_unicode_funcs_make_immutable (ufuncs). + This is especially useful if your code is a + library or framework that will have its own client programs. By + marking your Unicode function choices as immutable, you prevent + your own client programs from changing the + unicode_funcs configuration and introducing + inconsistencies and errors downstream. + + + You can retrieve the Unicode-functions configuration for + your buffer by calling hb_buffer_get_unicode_funcs(): + + + hb_unicode_funcs_t *ufunctions; + ufunctions = hb_buffer_get_unicode_funcs(buf); + + + The current version of unicode_funcs uses six functions: + + + + + hb_unicode_combining_class_func_t: + returns the Canonical Combining Class of a code point. + + + + + hb_unicode_general_category_func_t: + returns the General Category (gc) of a code point. + + + + + hb_unicode_mirroring_func_t: returns + the Mirroring Glyph code point (for bi-directional + replacement) of a code point. + + + + + hb_unicode_script_func_t: returns the + Script (sc) property of a code point. + + + + + hb_unicode_compose_func_t: returns the + canonical composition of a sequence of two code points. + + + + + hb_unicode_decompose_func_t: returns + the canonical decomposition of a code point. + + + + + Note, however, that future HarfBuzz releases may alter this set. + + + Each Unicode function has a corresponding setter, with which you + can assign a callback to your replacement function. For example, + to replace + hb_unicode_general_category_func_t, you can call + + + hb_unicode_funcs_set_general_category_func (*ufuncs, func, *user_data, destroy) + + + Virtualizing this set of Unicode functions is primarily intended + to improve portability. There is no need for every client + program to make the effort to replace the default options, so if + you are unsure, do not feel any pressure to customize + unicode_funcs. + +

+ Clusters and shaping + + In text shaping, a cluster is a sequence of + characters that needs to be treated as a single, indivisible + unit. A single letter or symbol can be a cluster of its + own. Other clusters correspond to longer subsequences of the + input code points — such as a ligature or conjunct form + — and require the shaper to ensure that the cluster is not + broken during the shaping process. + + + A cluster is distinct from a grapheme, + which is the smallest unit of meaning in a writing system or + script. + + + The definitions of the two terms are similar. However, clusters + are only relevant for script shaping and glyph layout. In + contrast, graphemes are a property of the underlying script, and + are of interest when client programs implement orthographic + or linguistic functionality. + + + For example, two individual letters are often two separate + graphemes. When two letters form a ligature, however, they + combine into a single glyph. They are then part of the same + cluster and are treated as a unit by the shaping engine — + even though the two original, underlying letters remain separate + graphemes. + + + HarfBuzz is concerned with clusters, not + with graphemes — although client programs using HarfBuzz + may still care about graphemes for other reasons from time to time. + + + During the shaping process, there are several shaping operations + that may merge adjacent characters (for example, when two code + points form a ligature or a conjunct form and are replaced by a + single glyph) or split one character into several (for example, + when decomposing a code point through the + ccmp feature). Operations like these alter + clusters; HarfBuzz tracks the changes to ensure that no clusters + get lost or broken during shaping. + + + HarfBuzz records cluster information independently from how + shaping operations affect the individual glyphs returned in an + output buffer. Consequently, a client program using HarfBuzz can + utilize the cluster information to implement features such as: + + + + + Correctly positioning the cursor within a shaped text run, + even when characters have formed ligatures, composed or + decomposed, reordered, or undergone other shaping operations. + + + + + Correctly highlighting a text selection that includes some, + but not all, of the characters in a word. + + + + + Applying text attributes (such as color or underlining) to + part, but not all, of a word. + + + + + Generating output document formats (such as PDF) with + embedded text that can be fully extracted. + + + + + Determining the mapping between input characters and output + glyphs, such as which glyphs are ligatures. + + + + + Performing line-breaking, justification, and other + line-level or paragraph-level operations that must be done + after shaping is complete, but which require examining + character-level properties. + + + +
+
+ Working with HarfBuzz clusters + + When you add text to a HarfBuzz buffer, each code point must be + assigned a cluster value. + + + This cluster value is an arbitrary number; HarfBuzz uses it only + to distinguish between clusters. Many client programs will use + the index of each code point in the input text stream as the + cluster value. This is for the sake of convenience; the actual + value does not matter. + + + Some of the shaping operations performed by HarfBuzz — + such as reordering, composition, decomposition, and substitution + — may alter the cluster values of some characters. The + final cluster values in the buffer at the end of the shaping + process will indicate to client programs which subsequences of + glyphs represent a cluster and, therefore, must not be + separated. + + + In addition, client programs can query the final cluster values + to discern other potentially important information about the + glyphs in the output buffer (such as whether or not a ligature + was formed). + + + For example, if the initial sequence of cluster values was: + + + 0,1,2,3,4 + + + and the final sequence of cluster values is: + + + 0,0,3,3 + + + then there are two clusters in the output buffer: the first + cluster includes the first two glyphs, and the second cluster + includes the third and fourth glyphs. It is also evident that a + ligature or conjunct has been formed, because there are fewer + glyphs in the output buffer (four) than there were code points + in the input buffer (five). + + + Although client programs using HarfBuzz are free to assign + initial cluster values in any manner they choose to, HarfBuzz + does offer some useful guarantees if the cluster values are + assigned in a monotonic (either non-decreasing or non-increasing) + order. + + + For buffers in the left-to-right (LTR) + or top-to-bottom (TTB) text flow direction, + HarfBuzz will preserve the monotonic property: client programs + are guaranteed that monotonically increasing initial cluster + values will be returned as monotonically increasing final + cluster values. + + + For buffers in the right-to-left (RTL) + or bottom-to-top (BTT) text flow direction, + the directionality of the buffer itself is reversed for final + output as a matter of design. Therefore, HarfBuzz inverts the + monotonic property: client programs are guaranteed that + monotonically increasing initial cluster values will be + returned as monotonically decreasing final + cluster values. + + + Client programs can adjust how HarfBuzz handles clusters during + shaping by setting the + cluster_level of the + buffer. HarfBuzz offers three levels of + clustering support for this property: + + + + Level 0 is the default and + reproduces the behavior of the old HarfBuzz library. + + + The distinguishing feature of level 0 behavior is that, at + the beginning of processing the buffer, all code points that + are categorized as marks, + modifier symbols, or + Emoji extended pictographic modifiers, + as well as the Zero Width Joiner and + Zero Width Non-Joiner code points, are + assigned the cluster value of the closest preceding code + point from different category. + + + In essence, whenever a base character is followed by a mark + character or a sequence of mark characters, those marks are + reassigned to the same initial cluster value as the base + character. This reassignment is referred to as + "merging" the affected clusters. This behavior is based on + the Grapheme Cluster Boundary specification in Unicode + Technical Report 29. + + + Client programs can specify level 0 behavior for a buffer by + setting its cluster_level to + HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES. + + + + + Level 1 tweaks the old behavior + slightly to produce better results. Therefore, level 1 + clustering is recommended for code that is not required to + implement backward compatibility with the old HarfBuzz. + + + Level 1 differs from level 0 by not merging the + clusters of marks and other modifier code points with the + preceding "base" code point's cluster. By preserving the + separate cluster values of these marks and modifier code + points, script shapers can perform additional operations + that might lead to improved results (for example, reordering + a sequence of marks). + + + Client programs can specify level 1 behavior for a buffer by + setting its cluster_level to + HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS. + + + + + Level 2 differs significantly in how it + treats cluster values. In level 2, HarfBuzz never merges + clusters. + + + This difference can be seen most clearly when HarfBuzz processes + ligature substitutions and glyph decompositions. In level 0 + and level 1, ligatures and glyph decomposition both involve + merging clusters; in level 2, neither of these operations + triggers a merge. + + + Client programs can specify level 2 behavior for a buffer by + setting its cluster_level to + HB_BUFFER_CLUSTER_LEVEL_CHARACTERS. + + + + + As mentioned earlier, client programs using HarfBuzz often + assign initial cluster values in a buffer by reusing the indices + of the code points in the input text. This gives a sequence of + cluster values that is monotonically increasing (for example, + 0,1,2,3,4). + + + It is not required that the cluster values + in a buffer be monotonically increasing. However, if the initial + cluster values in a buffer are monotonic and the buffer is + configured to use cluster level 0 or 1, then HarfBuzz + guarantees that the final cluster values in the shaped buffer + will also be monotonic. No such guarantee is made for cluster + level 2. + + + In levels 0 and 1, HarfBuzz implements the following conceptual + model for cluster values: + + + + + If the sequence of input cluster values is monotonic, the + sequence of cluster values will remain monotonic. + + + + + Each cluster value represents a single cluster. + + + + + Each cluster contains one or more glyphs and one or more + characters. + + + + + In practice, this model offers several benefits. Assuming that + the initial cluster values were monotonically increasing + and distinct before shaping began, then, in the final output: + + + + + All adjacent glyphs having the same final cluster + value belong to the same cluster. + + + + + Each character belongs to the cluster that has the highest + cluster value not larger than its + initial cluster value. + + + +
+ +
+ A clustering example for levels 0 and 1 + + The basic shaping operations affect clusters in a predictable + manner when using level 0 or level 1: + + + + + When two or more clusters merge, the + resulting merged cluster takes as its cluster value the + minimum of the incoming cluster values. + + + + + When a cluster decomposes, all of the + resulting child clusters inherit as their cluster value the + cluster value of the parent cluster. + + + + + When a character is reordered, the + reordered character and all clusters that the character + moves past as part of the reordering are merged into one cluster. + + + + + The functionality, guarantees, and benefits of level 0 and level + 1 behavior can be seen with some examples. First, let us examine + what happens with cluster values when shaping involves cluster + merging with ligatures and decomposition. + + + + Let's say we start with the following character sequence (top row) and + initial cluster values (bottom row): + + + A,B,C,D,E + 0,1,2,3,4 + + + During shaping, HarfBuzz maps these characters to glyphs from + the font. For simplicity, let us assume that each character maps + to the corresponding, identical-looking glyph: + + + A,B,C,D,E + 0,1,2,3,4 + + + Now if, for example, B and C + form a ligature, then the clusters to which they belong + "merge". This merged cluster takes for its cluster + value the minimum of all the cluster values of the clusters that + went in to the ligature. In this case, we get: + + + A,BC,D,E + 0,1 ,3,4 + + + because 1 is the minimum of the set {1,2}, which were the + cluster values of B and + C. + + + Next, let us say that the BC ligature glyph + decomposes into three components, and D also + decomposes into two components. Whenever a cluster decomposes, + its components each inherit the cluster value of their parent: + + + A,BC0,BC1,BC2,D0,D1,E + 0,1 ,1 ,1 ,3 ,3 ,4 + + + Next, if BC2 and D0 form a + ligature, then their clusters (cluster values 1 and 3) merge into + min(1,3) = 1: + + + A,BC0,BC1,BC2D0,D1,E + 0,1 ,1 ,1 ,1 ,4 + + + Note that the entirety of cluster 3 merges into cluster 1, not + just the D0 glyph. This reflects the fact + that the cluster must be treated as an + indivisible unit. + + + At this point, cluster 1 means: the character sequence + BCD is represented by glyphs + BC0,BC1,BC2D0,D1 and cannot be broken down any + further. + +
+
+ Reordering in levels 0 and 1 + + Another common operation in the more complex shapers is glyph + reordering. In order to maintain a monotonic cluster sequence + when glyph reordering takes place, HarfBuzz merges the clusters + of everything in the reordering sequence. + + + For example, let us again start with the character sequence (top + row) and initial cluster values (bottom row): + + + A,B,C,D,E + 0,1,2,3,4 + + + If D is reordered to the position immediately + before B, then HarfBuzz merges the + B, C, and + D clusters — all the clusters between + the final position of the reordered glyph and its original + position. This means that we get: + + + A,D,B,C,E + 0,1,1,1,4 + + + as the final cluster sequence. + + + Merging this many clusters is not ideal, but it is the only + sensible way for HarfBuzz to maintain the guarantee that the + sequence of cluster values remains monotonic and to retain the + true relationship between glyphs and characters. + +
+
+ The distinction between levels 0 and 1 + + The preceding examples demonstrate the main effects of using + cluster levels 0 and 1. The only difference between the two + levels is this: in level 0, at the very beginning of the shaping + process, HarfBuzz merges the cluster of each base character + with the clusters of all Unicode marks (combining or not) and + modifiers that follow it. + + + For example, let us start with the following character sequence + (top row) and accompanying initial cluster values (bottom row): + + + A,acute,B + 0,1 ,2 + + + The acute is a Unicode mark. If HarfBuzz is + using cluster level 0 on this sequence, then the + A and acute clusters will + merge, and the result will become: + + + A,acute,B + 0,0 ,2 + + + This merger is performed before any other script-shaping + steps. + + + This initial cluster merging is the default behavior of the + Windows shaping engine, and the old HarfBuzz codebase copied + that behavior to maintain compatibility. Consequently, it has + remained the default behavior in the new HarfBuzz codebase. + + + But this initial cluster-merging behavior makes it impossible + for client programs to implement some features (such as to + color diacritic marks differently from their base + characters). That is why, in level 1, HarfBuzz does not perform + the initial merging step. + + + For client programs that rely on HarfBuzz cluster values to + perform cursor positioning, level 0 is more convenient. But + relying on cluster boundaries for cursor positioning is wrong: cursor + positions should be determined based on Unicode grapheme + boundaries, not on shaping-cluster boundaries. As such, using + level 1 clustering behavior is recommended. + + + One final facet of levels 0 and 1 is worth noting. HarfBuzz + currently does not allow any + multiple-substitution GSUB lookups to + replace a glyph with zero glyphs (in other words, to delete a + glyph). + + + But, in some other situations, glyphs can be deleted. In + those cases, if the glyph being deleted is the last glyph of its + cluster, HarfBuzz makes sure to merge the deleted glyph's + cluster with a neighboring cluster. + + + This is done primarily to make sure that the starting cluster of the + text always has the cluster index pointing to the start of the text + for the run; more than one client program currently relies on this + guarantee. + + + Incidentally, Apple's CoreText does something different to + maintain the same promise: it inserts a glyph with id 65535 at + the beginning of the glyph string if the glyph corresponding to + the first character in the run was deleted. HarfBuzz might do + something similar in the future. + +
+
+ Level 2 + + HarfBuzz's level 2 cluster behavior uses a significantly + different model than that of level 0 and level 1. + + + The level 2 behavior is easy to describe, but it may be + difficult to understand in practical terms. In brief, level 2 + performs no merging of clusters whatsoever. + + + This means that there is no initial base-and-mark merging step + (as is done in level 0), and it means that reordering moves and + ligature substitutions do not trigger a cluster merge. + + + Only one shaping operation directly affects clusters when using + level 2: + + + + + When a cluster decomposes, all of the + resulting child clusters inherit as their cluster value the + cluster value of the parent cluster. + + + + + When glyphs do form a ligature (or when some other feature + substitutes multiple glyphs with one glyph) the cluster value + of the first glyph is retained as the cluster value for the + resulting ligature. + + + This occurrence sounds similar to a cluster merge, but it is + different. In particular, no subsequent characters — + including marks and modifiers — are affected. They retain + their previous cluster values. + + + Level 2 cluster behavior is ultimately less complex than level 0 + or level 1, but there are several cases for which processing + cluster values produced at level 2 may be tricky. + +
+ Ligatures with combining marks in level 2 + + The first example of how HarfBuzz's level 2 cluster behavior + can be tricky is when the text to be shaped includes combining + marks attached to ligatures. + + + Let us start with an input sequence with the following + characters (top row) and initial cluster values (bottom row): + + + A,acute,B,breve,C,circumflex + 0,1 ,2,3 ,4,5 + + + If the sequence A,B,C forms a ligature, + then these are the cluster values HarfBuzz will return under + the various cluster levels: + + + Level 0: + + + ABC,acute,breve,circumflex + 0 ,0 ,0 ,0 + + + Level 1: + + + ABC,acute,breve,circumflex + 0 ,0 ,0 ,5 + + + Level 2: + + + ABC,acute,breve,circumflex + 0 ,1 ,3 ,5 + + + Making sense of the level 2 result is the hardest for a client + program, because there is nothing in the cluster values that + indicates that B and C + formed a ligature with A. + + + In contrast, the "merged" cluster values of the mark glyphs + that are seen in the level 0 and level 1 output are evidence + that a ligature substitution took place. + +
+
+ Reordering in level 2 + + Another example of how HarfBuzz's level 2 cluster behavior + can be tricky is when glyphs reorder. Consider an input sequence + with the following characters (top row) and initial cluster + values (bottom row): + + + A,B,C,D,E + 0,1,2,3,4 + + + Now imagine D moves before + B in a reordering operation. The cluster + values will then be: + + + A,D,B,C,E + 0,3,1,2,4 + + + Next, if D forms a ligature with + B, the output is: + + + A,DB,C,E + 0,3 ,2,4 + + + However, in a different scenario, in which the shaping rules + of the script instead caused A and + B to form a ligature + before the D reordered, the + result would be: + + + AB,D,C,E + 0 ,3,2,4 + + + There is no way for a client program to differentiate between + these two scenarios based on the cluster values + alone. Consequently, client programs that use level 2 might + need to undertake additional work in order to manage cursor + positioning, text attributes, or other desired features. + +
+
+ Other considerations in level 2 + + There may be other problems encountered with ligatures under + level 2, such as if the direction of the text is forced to + the opposite of its natural direction (for example, Arabic text + that is forced into left-to-right directionality). But, + generally speaking, these other scenarios are minor corner + cases that are too obscure for most client programs to need to + worry about. + +

In order to shape this + buffer text with HarfBuzz, you will need also need a font + object. + + + HarfBuzz provides abstractions to help you cache and reuse the + heavier parts of working with binary fonts, so we will look at + how to do that. We will also look at how to work with the + FreeType font-rendering library and at how you can customize + HarfBuzz to work with other libraries. + + + Finally, we will look at how to work with OpenType variable + fonts, the latest update to the OpenType font format, and at + some other recent additions to OpenType. + + +
+ Font and face objects + + The outcome of shaping a run of text depends on the contents of + a specific font file (such as the substitutions and positioning + moves in the 'GSUB' and 'GPOS' tables), so HarfBuzz makes + accessing those internals fast. + + + An hb_face_t represents a face + in HarfBuzz. This data type is a wrapper around an + hb_blob_t blob that holds the contents of a binary + font file. Since HarfBuzz supports TrueType Collections and + OpenType Collections (each of which can include multiple + typefaces), a HarfBuzz face also requires an index number + specifying which typeface in the file you want to use. Most of + the font files you will encounter in the wild include just a + single face, however, so most of the time you would pass in + 0 as the index when you create a face: + + + hb_blob_t* blob = hb_blob_create_from_file(file); + ... + hb_face_t* face = hb_face_create(blob, 0); + + + On its own, a face object is not quite ready to use for + shaping. The typeface must be set to a specific point size in + order for some details (such as hinting) to work. In addition, + if the font file in question is an OpenType Variable Font, then + you may need to specify one or variation-axis settings (or a + named instance) in order to get the output you need. + + + In HarfBuzz, you do this by creating a font + object from your face. + + + Font objects also have the advantage of being considerably + lighter-weight than face objects (remember that a face contains + the contents of a binary font file mapped into memory). As a + result, you can cache and reuse a font object, but you could + also create a new one for each additional size you needed. + Creating new fonts incurs some additional overhead, of course, + but whether or not it is excessive is your call in the end. In + contrast, face objects are substantially larger, and you really + should cache them and reuse them whenever possible. + + + You can create a font object from a face object: + + + hb_font_t* hb_font = hb_font_create(hb_face); + + + After creating a font, there are a few properties you should + set. Many fonts enable and disable hints based on the size it + is used at, so setting this is important for font + objects. hb_font_set_ppem(font, x_ppem, + y_ppem) sets the pixels-per-EM value of the font. You + can also set the point size of the font with + hb_font_set_ptem(font, ptem). HarfBuzz uses the + industry standard 72 points per inch. + + + HarfBuzz lets you specify the degree subpixel precision you want + through a scaling factor. You can set horizontal and + vertical scaling factors on the + font by calling hb_font_set_scale(font, x_scale, + y_scale). + + + There may be times when you are handed a font object and need to + access the face object that it comes from. For that, you can call + + + hb_face = hb_font_get_face(hb_font); + + + You can also create a font object from an existing font object + using the hb_font_create_sub_font() + function. This creates a child font object that is initiated + with the same attributes as its parent; it can be used to + quickly set up a new font for the purpose of overriding a specific + font-functions method. + + + All face objects and font objects are lifecycle-managed by + HarfBuzz. After creating a face, you increase its reference + count with hb_face_reference(face) and + decrease it with + hb_face_destroy(face). Likewise, you + increase the reference count on a font with + hb_font_reference(font) and decrease it + with hb_font_destroy(font). + + + You can also attach user data to face objects and font objects. + +
+ +
+ Customizing font functions + + During shaping, HarfBuzz frequently needs to query font objects + to get at the contents and parameters of the glyphs in a font + file. It includes a built-in set of functions that is tailored + to working with OpenType fonts. However, as was the case with + Unicode functions in the buffers chapter, HarfBuzz also wants to + make it easy for you to assign a substitute set of font + functions if you are developing a program to work with a library + or platform that provides its own font functions. + + + Therefore, the HarfBuzz API defines a set of virtual + methods for accessing font-object properties, and you can + replace the defaults with your own selections without + interfering with the shaping process. Each font object in + HarfBuzz includes a structure called + font_funcs that serves as a vtable for the + font object. The virtual methods in + font_funcs are: + + + + + hb_font_get_font_h_extents_func_t: returns + the extents of the font for horizontal text. + + + + + hb_font_get_font_v_extents_func_t: returns + the extents of the font for vertical text. + + + + + hb_font_get_nominal_glyph_func_t: returns + the font's nominal glyph for a given code point. + + + + + hb_font_get_variation_glyph_func_t: returns + the font's glyph for a given code point when it is followed by a + given Variation Selector. + + + + + hb_font_get_nominal_glyphs_func_t: returns + the font's nominal glyphs for a series of code points. + + + + + hb_font_get_glyph_advance_func_t: returns + the advance for a glyph. + + + + + hb_font_get_glyph_h_advance_func_t: returns + the advance for a glyph for horizontal text. + + + + + hb_font_get_glyph_v_advance_func_t:returns + the advance for a glyph for vertical text. + + + + + hb_font_get_glyph_advances_func_t: returns + the advances for a series of glyphs. + + + + + hb_font_get_glyph_h_advances_func_t: returns + the advances for a series of glyphs for horizontal text . + + + + + hb_font_get_glyph_v_advances_func_t: returns + the advances for a series of glyphs for vertical text. + + + + + hb_font_get_glyph_origin_func_t: returns + the origin coordinates of a glyph. + + + + + hb_font_get_glyph_h_origin_func_t: returns + the origin coordinates of a glyph for horizontal text. + + + + + hb_font_get_glyph_v_origin_func_t: returns + the origin coordinates of a glyph for vertical text. + + + + + hb_font_get_glyph_extents_func_t: returns + the extents for a glyph. + + + + + hb_font_get_glyph_contour_point_func_t: + returns the coordinates of a specific contour point from a glyph. + + + + + hb_font_get_glyph_name_func_t: returns the + name of a glyph (from its glyph index). + + + + + hb_font_get_glyph_from_name_func_t: returns + the glyph index that corresponds to a given glyph name. + + + + + You can fetch the font-functions configuration for a font object + by calling hb_font_get_font_funcs(): + + + hb_font_funcs_t *ffunctions; + ffunctions = hb_font_get_font_funcs (font); + + + The individual methods can each be replaced with their own setter + function, such as + hb_font_funcs_set_nominal_glyph_func(*ffunctions, + func, *user_data, destroy). + + + Font-functions structures can be reused for multiple font + objects, and can be reference counted with + hb_font_funcs_reference() and + hb_font_funcs_destroy(). Just like other + objects in HarfBuzz, you can set user-data for each + font-functions structure and assign a destroy callback for + it. + + + You can also mark a font-functions structure as immutable, + with hb_font_funcs_make_immutable(). This + is especially useful if your code is a library or framework that + will have its own client programs. By marking your + font-functions structures as immutable, you prevent your client + programs from changing the configuration and introducing + inconsistencies and errors downstream. + +
+ +
+ Font objects and HarfBuzz's native OpenType implementation + + By default, whenever HarfBuzz creates a font object, it will + configure the font to use a built-in set of font functions that + supports contemporary OpenType font internals. If you want to + work with OpenType or TrueType fonts, you should be able to use + these functions without difficulty. + + + Many of the methods in the font-functions structure deal with + the fundamental properties of glyphs that are required for + shaping text: extents (the maximums and minimums on each axis), + origins (the (0,0) coordinate point which + glyphs are drawn in reference to), and advances (the amount that + the cursor needs to be moved after drawing each glyph, including + any empty space for the glyph's side bearings). + + + As you can see in the list of functions, there are separate "horizontal" + and "vertical" variants depending on whether the text is set in + the horizontal or vertical direction. For some scripts, fonts + that are designed to support text set horizontally or vertically (for + example, in Japanese) may include metrics for both text + directions. When fonts don't include this information, HarfBuzz + does its best to transform what the font provides. + + + In addition to the direction-specific functions, HarfBuzz + provides some higher-level functions for fetching information + like extents and advances for a glyph. If you call + + + hb_font_get_glyph_advance_for_direction(font, direction, extents); + + + then you can provide any hb_direction_t as the + direction parameter, and HarfBuzz will + use the correct function variant for the text direction. There + are similar higher-level versions of the functions for fetching + extents, origin coordinates, and contour-point + coordinates. There are also addition and subtraction functions + for moving points with respect to the origin. + + + There are also methods for fetching the glyph ID that + corresponds to a Unicode code point (possibly when followed by a + variation-selector code point), fetching the glyph name from the + font, and fetching the glyph ID that corresponds to a glyph name + you already have. + + + HarfBuzz also provides functions for converting between glyph + names and string + variables. hb_font_glyph_to_string(font, glyph, s, + size) retrieves the name for the glyph ID + glyph from the font object. It generates a + generic name of the form gidDDD (where DDD is + the glyph index) if there is no name for the glyph in the + font. The hb_font_glyph_from_string(font, s, len, + glyph) takes an input string s + and looks for a glyph with that name in the font, returning its + glyph ID in the glyph + output parameter. It automatically parses + gidDDD and uniUUUU strings. + +
+ + + + + + +
+ Working with OpenType Variable Fonts + + If you are working with OpenType Variable Fonts, there are a few + additional functions you should use to specify the + variation-axis settings of your font object. Without doing so, + your variable font's font object can still be used, but only at + the default setting for every axis (which, of course, is + sometimes what you want, but does not cover general usage). + + + HarfBuzz manages variation settings in the + hb_variation_t data type, which holds a tag for the + variation-axis identifier tag and a value for its + setting. You can retrieve the list of variation axes in a font + binary from the face object (not from a font object, notably) by + calling hb_ot_var_get_axis_count(face) to + find the number of axes, then using + hb_ot_var_get_axis_infos() to collect the + axis structures: + + + axes = hb_ot_var_get_axis_count(face); + ... + hb_ot_var_get_axis_infos(face, 0, axes, axes_array); + + + For each axis returned in the array, you can can access the + identifier in its tag. HarfBuzz also has + tag definitions predefined for the five standard axes specified + in OpenType (ital for italic, + opsz for optical size, + slnt for slant, wdth for + width, and wght for weight). Each axis also + has a min_value, a + default_value, and a max_value. + + + To set your font object's variation settings, you call the + hb_font_set_variations() function with an + array of hb_variation_t variation settings. Let's + say our font has weight and width axes. We need to specify each + of the axes by tag and assign a value on the axis: + + + unsigned int variation_count = 2; + hb_variation_t variation_data[variation_count]; + variation_data[0].tag = HB_OT_TAG_VAR_AXIS_WIDTH; + variation_data[1].tag = HB_OT_TAG_VAR_AXIS_WEIGHT; + variation_data[0].value = 80; + variation_data[1].value = 750; + ... + hb_font_set_variations(font, variation_data, variation_count); + + + That should give us a slightly condensed font ("normal" on the + wdth axis is 100) at a noticeably bolder + weight ("regular" is 400 on the wght axis). + + + In practice, though, you should always check that the value you + want to set on the axis is within the + [min_value,max_value] + range actually implemented in the font's variation axis. After + all, a font might only provide lighter-than-regular weights, and + setting a heavier value on the wght axis will + not change that. + + + Once your variation settings are specified on your font object, + however, shaping with a variable font is just like shaping a + static font. + +

+ An overview of the HarfBuzz shaping API + + The core of the HarfBuzz shaping API is the function + hb_shape(). This function takes a font, a + buffer containing a string of Unicode codepoints and + (optionally) a list of font features as its input. It replaces + the codepoints in the buffer with the corresponding glyphs from + the font, correctly ordered and positioned, and with any of the + optional font features applied. + + + In addition to holding the pre-shaping input (the Unicode + codepoints that comprise the input string) and the post-shaping + output (the glyphs and positions), a HarfBuzz buffer has several + properties that affect shaping. The most important are the + text-flow direction (e.g., left-to-right, right-to-left, + top-to-bottom, or bottom-to-top), the script tag, and the + language tag. + + + + For input string buffers, flags are available to denote when the + buffer represents the beginning or end of a paragraph, to + indicate whether or not to visibly render Unicode Default + Ignorable codepoints, and to modify the cluster-merging + behavior for the buffer. For shaped output buffers, the + individual X and Y offsets and advances + (the logical dimensions) of each glyph are + accessible. HarfBuzz also flags glyphs as + UNSAFE_TO_BREAK if breaking the string at + that glyph (e.g., in a line-breaking or hyphenation process) + would require re-shaping the text. + + + + HarfBuzz also provides methods to compare the contents of + buffers, join buffers, normalize buffer contents, and handle + invalid codepoints, as well as to determine the state of a + buffer (e.g., input codepoints or output glyphs). Buffer + lifecycles are managed and all buffers are reference-counted. + + + + Although the default hb_shape() function is + sufficient for most use cases, a variant is also provide that + lets you specify which of HarfBuzz's shapers to use on a buffer. + + + + HarfBuzz can read TrueType fonts, TrueType collections, OpenType + fonts, and OpenType collections. Functions are provided to query + font objects about metrics, Unicode coverage, available tables and + features, and variation selectors. Individual glyphs can also be + queried for metrics, variations, and glyph names. OpenType + variable fonts are supported, and HarfBuzz allows you to set + variation-axis coordinates on font objects. + + + + HarfBuzz provides glue code to integrate with various other + libraries, including FreeType, GObject, and CoreText. Support + for integrating with Uniscribe and DirectWrite is experimental + at present. + +
+ +
+ Terminology + + + + + + + script + + + In text shaping, a script is a + writing system: a set of symbols, rules, and conventions + that is used to represent a language or multiple + languages. + + + In general computing lingo, the word "script" can also + be used to mean an executable program (usually one + written in a human-readable programming language). For + the sake of clarity, HarfBuzz documents will always use + more specific terminology when referring to this + meaning, such as "Python script" or "shell script." In + all other instances, "script" refers to a writing system. + + + For developers using HarfBuzz, it is important to note + the distinction between a script and a language. Most + scripts are used to write a variety of different + languages, and many languages may be written in more + than one script. + + + + + + shaper + + + In HarfBuzz, a shaper is a + handler for a specific script-shaping model. HarfBuzz + implements separate shapers for Indic, Arabic, Thai and + Lao, Khmer, Myanmar, Tibetan, Hangul, Hebrew, the + Universal Shaping Engine (USE), and a default shaper for + non-complex scripts. + + + + + + cluster + + + In text shaping, a cluster is a + sequence of codepoints that must be treated as an + indivisible unit. Clusters can include code-point + sequences that form a ligature or base-and-mark + sequences. Tracking and preserving clusters is important + when shaping operations might separate or reorder + code points. + + + HarfBuzz provides three cluster + levels that implement different + approaches to the problem of preserving clusters during + shaping operations. + + + + + + grapheme + + + In linguistics, a grapheme is one + of the indivisible units that make up a writing system or + script. Often, graphemes are individual symbols (letters, + numbers, punctuation marks, logograms, etc.) but, + depending on the writing system, a particular grapheme + might correspond to a sequence of several Unicode code + points. + + + In practice, HarfBuzz and other text-shaping engines + are not generally concerned with graphemes. However, it + is important for developers using HarfBuzz to recognize + that there is a difference between graphemes and shaping + clusters (see above). The two concepts may overlap + frequently, but there is no guarantee that they will be + identical. + + + + + + syllable + + + In linguistics, a syllable is an + a sequence of sounds that makes up a building block of a + particular language. Every language has its own set of + rules describing what constitutes a valid syllable. + + + For text-shaping purposes, the various definitions of + "syllable" are important because script-specific shaping + operations may be applied at the syllable level. For + example, a reordering rule might specify that a vowel + mark be reordered to the beginning of the syllable. + + + Syllables will consist of one or more Unicode code + points. The definition of a syllable for a particular + writing system might correspond to how HarfBuzz + identifies clusters (see above) for the same writing + system. However, it is important for developers using + HarfBuzz to recognize that there is a difference between + syllables and shaping clusters. The two concepts may + overlap frequently, but there is no guarantee that they + will be identical. + + + + + +
+ + +
+ A simple shaping example + + + Below is the simplest HarfBuzz shaping example possible. + + + + + Create a buffer and put your text in it. + + + + + #include <hb.h> + hb_buffer_t *buf; + buf = hb_buffer_create(); + hb_buffer_add_utf8(buf, text, -1, 0, -1); + + + + + Set the script, language and direction of the buffer. + + + + + hb_buffer_set_direction(buf, HB_DIRECTION_LTR); + hb_buffer_set_script(buf, HB_SCRIPT_LATIN); + hb_buffer_set_language(buf, hb_language_from_string("en", -1)); + + + + + Create a face and a font, using FreeType for now. + + + + + #include <hb-ft.h> + FT_New_Face(ft_library, font_path, index, &face); + FT_Set_Char_Size(face, 0, 1000, 0, 0); + hb_font_t *font = hb_ft_font_create(face); + + + + + Shape! + + + + + hb_shape(font, buf, NULL, 0); + + + + + Get the glyph and position information. + + + + + hb_glyph_info_t *glyph_info = hb_buffer_get_glyph_infos(buf, &glyph_count); + hb_glyph_position_t *glyph_pos = hb_buffer_get_glyph_positions(buf, &glyph_count); + + + + + Iterate over each glyph. + + + + + for (i = 0; i < glyph_count; ++i) { + glyphid = glyph_info[i].codepoint; + x_offset = glyph_pos[i].x_offset / 64.0; + y_offset = glyph_pos[i].y_offset / 64.0; + x_advance = glyph_pos[i].x_advance / 64.0; + y_advance = glyph_pos[i].y_advance / 64.0; + draw_glyph(glyphid, cursor_x + x_offset, cursor_y + y_offset); + cursor_x += x_advance; + cursor_y += y_advance; + } + + + + + Tidy up. + + + + + hb_buffer_destroy(buf); + hb_font_destroy(hb_ft_font); + + + + This example shows enough to get us started using HarfBuzz.

+ An overview of data types in HarfBuzz + + HarfBuzz features two kinds of data types: non-opaque, + pass-by-value types and opaque, heap-allocated types. This kind + of separation is common in C libraries that have to provide + API/ABI compatibility (almost) indefinitely. + + + Value types: The non-opaque, pass-by-value + types include integer types, enums, and small structs. Exposing + a struct in the public API makes it impossible to expand the + struct in the future. As such, exposing structs is reserved for + cases where it’s extremely inefficient to do otherwise. + + + In HarfBuzz, several structs, like hb_glyph_info_t and + hb_glyph_position_t, fall into that efficiency-sensitive + category and are non-opaque. + + + For all non-opaque structs where future extensibility may be + necessary, reserved members are included to hold space for + possible future members. As such, it’s important to provide + equal(), and hash() + methods for such structs, allowing users of the API do + effectively deal with the type without having to + adapt their code to future changes. + + + Important value types provided by HarfBuzz include the structs + for working with Unicode code points, glyphs, and tags for font + tables and features, as well as the enums for many Unicode and + OpenType properties. + +
+ +
+ Objects in HarfBuzz + + Object types: Opaque struct types are used + for what HarfBuzz loosely calls "objects." This doesn’t have + much to do with the terminology from object-oriented programming + (OOP), although some of the concepts are similar. + + + In HarfBuzz, all object types provide certain + lifecycle-management APIs. Objects are reference-counted, and + constructed with various create() methods, referenced via + reference() and dereferenced using + destroy(). + + + For example, + the hb_buffer_t object has + hb_buffer_create() as its constructor, + hb_buffer_reference() to reference, and + hb_buffer_destroy() to dereference. + + + After construction, each object's properties are accessible only + through the setter and getter functions described in the API + Reference manual. + + + Key object types provided by HarfBuzz include: + + + + + blobs, which act as low-level wrappers around binary + data. Blobs are typically used to hold the contents of a + binary font file. + + + + + faces, which represent typefaces from a + font file, but without specific parameters (such as size) set. + + + + + fonts, which represent instances of a + face with all of their parameters specified. + + + + + buffers, which hold Unicode code points + for characters (before shaping) and the shaped glyph output + (after shaping). + + + + + shape plans, which store the settings + that HarfBuzz will use when shaping a particular text + segment. Shape plans are not generally used by client + programs directly, but as we will see in a later chapter, + they are still valuable to understand. + + + + +
+ + + +
+ Object lifecycle management + + Each object type in HarfBuzz provides a + create() method. Some object types provide + additional variants of create() to handle + special cases or to speed up common tasks; those variants are + documented in the API reference. For example, + hb_blob_create_from_file() constructs a new + blob directly from the contents of a file. + + + All objects are created with an initial reference count of + 1. Client programs can increase the reference + count on an object by calling its + reference() method. Whenever a client + program is finished with an object, it should call its + corresponding destroy() method. The destroy + method will decrease the reference count on the object and, + whenever the reference count reaches zero, it will also destroy + the object and free all of the associated memory. + + + All of HarfBuzz's object-lifecycle-management APIs are + thread-safe (unless you compiled HarfBuzz from source with the + HB_NO_MT configuration flag), even when the + object as a whole is not thread-safe. + It is also permissible to reference() or to + destroy() the NULL + value. + + + Some objects are thread-safe after they have been constructed + and set up. The general pattern is to + create() the object, make a few + set_*() calls to set up the + object, and then use it without further modification. + + + To ensure that such an object is not modified, client programs + can explicitly mark an object as immutable. HarfBuzz provides + make_immutable() methods to mark an object + as immutable and is_immutable() methods to + test whether or not an object is immutable. Attempts to use + setter functions on immutable objects will fail silently; see the API + Reference manual for specifics. + + + Note also that there are no "make mutable" methods. If client + programs need to alter an object previously marked as immutable, + they will need to make a duplicate of the original. + + + Finally, object constructors (and, indeed, as much of the + shaping API as possible) will never return + NULL. Instead, if there is an allocation + error, each constructor will return an “empty” object + singleton. + + + These empty-object singletons are inert and safe (although + typically useless) to pass around. This design choice avoids + having to check for NULL pointers all + throughout the code. + + + In addition, this “empty” object singleton can also be accessed + using the get_empty() method of the object + type in question. + +
+ + +
+ User data + + To better integrate with client programs, HarfBuzz's objects + offer a "user data" mechanism that can be used to attach + arbitrary data to the object. User-data attachment can be + useful for tying the lifecycles of various pieces of data + together, or for creating language bindings. + + + Each object type has a set_user_data() + method and a get_user_data() method. The + set_user_data() methods take a client-provided + key and a pointer, + user_data, pointing to the data itself. Once + the key-data pair has been attached to the object, the + get_user_data() method can be called with + the key, returning the user_data pointer. + + + The set_user_data() methods also support an + optional destroy callback. Client programs + can set the destroy callback and receive + notification from HarfBuzz whenever the object is destructed. + + + Finally, each set_user_data() method allows + the client program to set a replace Boolean + indicating whether or not the function call should replace any + existing user_data + associated with the specified key. + +
+ + + +
+ Blobs + + While most of HarfBuzz's object types are specific to the + shaping process, blobs are somewhat + different. + + + Blobs are an abstraction desgined to negotiate lifecycle and + permissions for raw pieces of data. For example, when you load + the raw font data into memory and want to pass it to HarfBuzz, + you do so in a hb_blob_t wrapper. + + + This allows you to take advantage of HarffBuzz's + reference-counting and destroy + callbacks. If you allocated the memory for the data using + malloc(), you would create the blob using + + + hb_blob_create (data, length, HB_MEMORY_MODE_WRITABLE, NULL, free) + + + That way, HarfBuzz will call free() on the + allocated memory whenever the blob drops its last reference and + is deconstructed. Consequently, the user code can stop worrying + about freeing memory and let the reference-counting machinery + take care of that. + +

If the font has an AAT + "kerx" table, then it is used for positioning; if not, but + there is a GPOS table, then the GPOS table is used. If neither + table is found, but there is a "kern" table, then HarfBuzz will + use the "kern" table. If there is no "kerx", no GPOS, and no + "kern", HarfBuzz will fall back to positioning marks itself. + + + With a well-behaved OpenType font, you expect GDEF, GSUB, and + GPOS tables to all be applied. HarfBuzz implements the + script-specific shaping models in internal functions, rather + than in the public API. + + + The algorithms + used for complex scripts can be quite involved; HarfBuzz tries + to be compatible with the OpenType Layout specification + and, wherever there is any ambiguity, HarfBuzz attempts to replicate the + output of Microsoft's Uniscribe engine. See the Microsoft + Typography pages for more detail. + + + In general, though, all that you need to know is that + hb_shape() returns the results of shaping + in the same buffer that you provided. The buffer's content type + will now be set to + HB_BUFFER_CONTENT_TYPE_GLYPHS, indicating + that it contains shaped output, rather than input text. You can + now extract the glyph information and positioning arrays: + + + hb_glyph_info_t *glyph_info = hb_buffer_get_glyph_infos(buf, &glyph_count); + hb_glyph_position_t *glyph_pos = hb_buffer_get_glyph_positions(buf, &glyph_count); + + + The glyph information array holds a hb_glyph_info_t + for each output glyph, which has two fields: + codepoint and + cluster. Whereas, in the input buffer, + the codepoint field contained the Unicode + code point, it now contains the glyph ID of the corresponding + glyph in the font. The cluster field is + an integer that you can use to help identify when shaping has + reordered, split, or combined code points; we will say more + about that in the next chapter. + + + The glyph positions array holds a corresponding + hb_glyph_position_t for each output glyph, + containing four fields: x_advance, + y_advance, + x_offset, and + y_offset. The advances tell you how far + you need to move the drawing point after drawing this glyph, + depending on whether you are setting horizontal text (in which + case you will have x advances) or vertical text (for which you + will have y advances). The x and y offsets tell you where to + move to start drawing the glyph; usually you will have both and + x and a y offset, regardless of the text direction. + + + Most of the time, you will rely on a font-rendering library or + other graphics library to do the actual drawing of glyphs, so + you will need to iterate through the glyphs in the buffer and + pass the corresponding values off. + +
+ +
+ OpenType features + + OpenType features enable fonts to include smart behavior, + implemented as "lookup" rules stored in the GSUB and GPOS + tables. The OpenType specification defines a long list of + standard features that fonts can use for these behaviors; each + feature has a four-character reserved name and a well-defined + semantic meaning. + + + Some OpenType features are defined for the purpose of supporting + complex-script shaping, and are automatically activated, but + only when a buffer's script property is set to a script that the + feature supports. + + + Other features are more generic and can apply to several (or + any) script, and shaping engines are expected to implement + them. By default, HarfBuzz activates several of these features + on every text run. They include abvm, + blwm, ccmp, + locl, mark, + mkmk, and rlig. + + + In addition, if the text direction is horizontal, HarfBuzz + also applies the calt, + clig, curs, + dist, kern, + liga, rclt, + and frac features. + + + If the text direction is vertical, HarfBuzz applies + the vert feature by default. + + + Still other features are designed to be purely optional and left + up to the application or the end user to enable or disable as desired. + + + You can adjust the set of features that HarfBuzz applies to a + buffer by supplying an array of hb_feature_t + features as the third argument to + hb_shape(). For a simple case, let's just + enable the dlig feature, which turns on any + "discretionary" ligatures in the font: + + + hb_feature_t userfeatures[1]; + userfeatures[0].tag = HB_TAG('d','l','i','g'); + userfeatures[0].value = 1; + userfeatures[0].start = HB_FEATURE_GLOBAL_START; + userfeatures[0].end = HB_FEATURE_GLOBAL_END; + + + HB_FEATURE_GLOBAL_END and + HB_FEATURE_GLOBAL_END are macros we can use + to indicate that the features will be applied to the entire + buffer. We could also have used a literal 0 + for the start and a -1 to indicate the end of + the buffer (or have selected other start and end positions, if needed). + + + When we pass the userfeatures array to + hb_shape(), any discretionary ligature + substitutions from our font that match the text in our buffer + will get performed: + + + hb_shape(font, buf, userfeatures, num_features); + + + Just like we enabled the dlig feature by + setting its value to + 1, you would disable a feature by setting its + value to 0. Some + features can take other value settings; + be sure you read the full specification of each feature tag to + understand what it does and how to control it. + +
+ +
+ Shaper selection + + The basic version of hb_shape() determines + its shaping strategy based on examining the capabilities of the + font file. OpenType font tables cause HarfBuzz to try the + ot shaper, while AAT font tables cause HarfBuzz to try the + aat shaper. + + + In the real world, however, a font might include some unusual + mix of tables, or one of the tables might simply be broken for + the script you need to shape. So, sometimes, you might not + want to rely on HarfBuzz's process for deciding what to do, and + just tell hb_shape() what you want it to try. + + + hb_shape_full() is an alternate shaping + function that lets you supply a list of shapers for HarfBuzz to + try, in order, when shaping your buffer. For example, if you + have determined that HarfBuzz's attempts to work around broken + tables gives you better results than the AAT shaper itself does, + you might move the AAT shaper to the end of your list of + preferences and call hb_shape_full() + + + char *shaperprefs[3] = {"ot", "default", "aat"}; + ... + hb_shape_full(font, buf, userfeatures, num_features, shaperprefs); + + + to get results you are happier with. + + + You may also want to call + hb_shape_list_shapers() to get a list of + the shapers that were built at compile time in your copy of HarfBuzz. + +
+ +
+ Plans and caching + + Internally, HarfBuzz uses a structure called a shape plan to + track its decisions about how to shape the contents of a + buffer. The hb_shape() function builds up the shape plan by + examining segment properties and by inspecting the contents of + the font. + + + This process can involve some decision-making and + trade-offs — for example, HarfBuzz inspects the GSUB and GPOS + lookups for the script and language tags set on the segment + properties, but it falls back on the lookups under the + DFLT tag (and sometimes other common tags) + if there are actually no lookups for the tag requested. + + + HarfBuzz also includes some work-arounds for + handling well-known older font conventions that do not follow + OpenType or Unicode specifications, for buggy system fonts, and for + peculiarities of Microsoft Uniscribe. All of that means that a + shape plan, while not something that you should edit directly in + client code, still might be an object that you want to + inspect. Furthermore, if resources are tight, you might want to + cache the shape plan that HarfBuzz builds for your buffer and + font, so that you do not have to rebuild it for every shaping call. + + + You can create a cacheable shape plan with + hb_shape_plan_create_cached(face, props, + user_features, num_user_features, shaper_list), where + face is a face object (not a font object, + notably), props is an + hb_segment_properties_t, + user_features is an array of + hb_feature_ts (with length + num_user_features), and + shaper_list is a list of shapers to try. + + + Shape plans are objects in HarfBuzz, so there are + reference-counting functions and user-data attachment functions + you can + use. hb_shape_plan_reference(shape_plan) + increases the reference count on a shape plan, while + hb_shape_plan_destroy(shape_plan) decreases + the reference count, destroying the shape plan when the last + reference is dropped. + + + You can attach user data to a shaper (with a key) using the + hb_shape_plan_set_user_data(shape_plan,key,data,destroy,replace) + function, optionally supplying a destroy + callback to use. You can then fetch the user data attached to a + shape plan with + hb_shape_plan_get_user_data(shape_plan, key). + +

+ Text shaping + + Text shaping is the process of transforming a sequence of Unicode + codepoints that represent individual characters (letters, + diacritics, tone marks, numbers, symbols, etc.) into the + orthographically and linguistically correct two-dimensional layout + of glyph shapes taken from a specified font. + + + For some writing systems (or scripts) and + languages, the process is simple, requiring the shaper to do + little more than advance the horizontal position forward by the + correct amount for each successive glyph. + + + But, for complex scripts, any combination of + several shaping operations may be required, and the rules for how + and when they are applied vary from script to script. HarfBuzz and + other shaping engines implement these rules. + + + The exact rules and necessary operations for a particular script + constitute a shaping model. OpenType + specifies a set of shaping models that covers all of + Unicode. Other shaping models are available, however, including + Graphite and Apple Advanced Typography (AAT). + +
+ +
+ Complex scripts + + In text-shaping terminology, scripts are generally classified as + either complex or non-complex. + + + Complex scripts are those for which transforming the input + sequence into the final layout requires some combination of + operations—such as context-dependent substitutions, + context-dependent mark positioning, glyph-to-glyph joining, + glyph reordering, or glyph stacking. + + + In some complex scripts, the shaping rules require that a text + run be divided into syllables before the operations can be + applied. Other complex scripts may apply shaping operations over + entire words or over the entire text run, with no subdivision + required. + + + Non-complex scripts, by definition, do not require these + operations. However, correctly shaping a text run in a + non-complex script may still involve Unicode normalization, + ligature substitutions, mark positioning, kerning, and applying + other font features. The key difference is that a text run in a + non-complex script can be processed sequentially and in the same + order as the input sequence of Unicode codepoints, without + requiring an analysis stage. + +
+ +
+ Shaping operations + + Shaping a complex-script text run involves transforming the + input sequence of Unicode codepoints with some combination of + operations that is specified in the shaping model for the + script. + + + The specific conditions that trigger a given operation for a + text run varies from script to script, as do the order that the + operations are performed in and which codepoints are + affected. However, the same general set of shaping operations is + common to all of the complex-script shaping models. + + + + + + A reordering operation moves a glyph + from its original ("logical") position in the sequence to + some other ("visual") position. + + + The shaping model for a given complex script might involve + more than one reordering step. + + + + + + A joining operation replaces a glyph + with an alternate form that is designed to connect with one + or more of the adjacent glyphs in the sequence. + + + + + + A contextual substitution operation + replaces either a single glyph or a subsequence of several + glyphs with an alternate glyph. This substitution is + performed when the original glyph or subsequence of glyphs + occurs in a specified position with respect to the + surrounding sequence. For example, one substitution might be + performed only when the target glyph is the first glyph in + the sequence, while another substitution is performed only + when a different target glyph occurs immediately after a + particular string pattern. + + + The shaping model for a given complex script might involve + multiple contextual-substitution operations, each applying + to different target glyphs and patterns, and which are + performed in separate steps. + + + + + + A contextual positioning operation + moves the horizontal and/or vertical position of a + glyph. This positioning move is performed when the glyph + occurs in a specified position with respect to the + surrounding sequence. + + + Many contextual positioning operations are used to place + mark glyphs (such as diacritics, vowel + signs, and tone markers) with respect to + base glyphs. However, some complex + scripts may use contextual positioning operations to + correctly place base glyphs as well, such as + when the script uses stacking characters. + + + + +
+ +
+ Unicode character categories + + Shaping models are typically specified with respect to how + scripts are defined in the Unicode standard. + + + Every codepoint in the Unicode Character Database (UCD) is + assigned a Unicode General Category (UGC), + which provides the most fundamental information about the + codepoint: whether the codepoint represents a + Letter, a Mark, a + Number, Punctuation, a + Symbol, a Separator, + or something else (Other). + + + These UGC properties are "Major" categories. Each codepoint is + further assigned to a "minor" category within its Major + category, such as "Letter, uppercase" (Lu) or + "Letter, modifier" (Lm). + + + Shaping models are concerned primarily with Letter and Mark + codepoints. The minor categories of Mark codepoints are + particularly important for shaping. Marks can be nonspacing + (Mn), spacing combining + (Mc), or enclosing (Me). + + + In addition to the UGC property, codepoints in the Indic and + Southeast Asian scripts are also assigned + Unicode Indic Syllabic Category (UISC) and + Unicode Indic Positional Category (UIPC) + properties that provide more detailed information needed for + shaping. + + + The UISC property sub-categorizes Letters and Marks according to + common script-shaping behaviors. For example, UISC distinguishes + between consonant letters, vowel letters, and vowel marks. The + UIPC property sub-categorizes Mark codepoints by the relative visual + position that they occupy (above, below, right, left, or in + multiple positions). + + + Some complex scripts require that the text run be split into + syllables. What constitutes a valid syllable in these + scripts is specified in regular expressions, formed from the + Letter and Mark codepoints, that take the UISC and UIPC + properties into account. + + +
+ +
+ Text runs + + Real-world text usually contains codepoints from a mixture of + different Unicode scripts (including punctuation, numbers, symbols, + white-space characters, and other codepoints that do not belong + to any script). Real-world text may also be marked up with + formatting that changes font properties (including the font, + font style, and font size). + + + For shaping purposes, all real-world text streams must be first + segmented into runs that have a uniform set of properties. + + + In particular, shaping models always assume that every codepoint + in a text run has the same direction, + script tag, and + language tag. + +
+ +
+ OpenType shaping models + + OpenType provides shaping models for the following scripts: + + + + + + The default shaping model handles all + non-complex scripts, and may also be used as a fallback for + handling unrecognized scripts. + + + + + + The Indic shaping model handles the Indic + scripts Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, + Malayalam, Oriya, Tamil, Telugu, and Sinhala. + + + The Indic shaping model was revised significantly in + 2005. To denote the change, a new set of script + tags was assigned for Bengali, Devanagari, + Gujarati, Gurmukhi, Kannada, Malayalam, Oriya, Tamil, and + Telugu. For the sake of clarity, the term "Indic2" is + sometimes used to refer to the current, revised shaping + model. + + + + + + The Arabic shaping model supports + Arabic, Mongolian, N'Ko, Syriac, and several other connected + or cursive scripts. + + + + + + The Thai/Lao shaping model supports + the Thai and Lao scripts. + + + + + + The Khmer shaping model supports the + Khmer script. + + + + + + The Myanmar shaping model supports the + Myanmar (or Burmese) script. + + + + + + The Tibetan shaping model supports the + Tibetan script. + + + + + + The Hangul shaping model supports the + Hangul script. + + + + + + The Hebrew shaping model supports the + Hebrew script. + + + + + + The Universal Shaping Engine (USE) + shaping model supports complex scripts not covered by one of + the above, script-specific shaping models, including + Javanese, Balinese, Buginese, Batak, Chakma, Lepcha, Modi, + Phags-pa, Tagalog, Siddham, Sundanese, Tai Le, Tai Tham, Tai + Viet, and many others. + + + + + + Text runs that do not fall under one of the above shaping + models may still require processing by a shaping engine. Of + particular note is Emoji shaping, which + may involve variation-selector sequences and glyph + substitution. Emoji shaping is handled by the default + shaping model. + + + + + +
+ +
+ Graphite shaping + + In contrast to OpenType shaping, Graphite shaping does not + specify a predefined set of shaping models or a set of supported + scripts. + + + Instead, each Graphite font contains a complete set of rules that + implement the required shaping model for the intended + script. These rules include finite-state machines to match + sequences of codepoints to the shaping operations to perform. + + + Graphite shaping can perform the same shaping operations used in + OpenType shaping, as well as other functions that have not been + defined for OpenType shaping. + +

+ Command-line tools + + HarfBuzz include three command-line tools: + hb-shape, hb-view, and + hb-subset. They can be used to examine + HarfBuzz's functionality, debug font binaries, or explore the + various shaping models and features from a terminal. + + +
+ hb-shape + + hb-shape allows you to run HarfBuzz's + hb_shape() function on an input string and + to examine the outcome, in human-readable form, as terminal + output. hb-shape does + not render the results of the shaping call + into rendered text (you can use hb-view, below, for + that). Instead, it prints out the final glyph indices and + positions, taking all shaping operations into account, as if the + input string were a HarfBuzz input buffer. + + + You can specify the font to be used for shaping and, with + command-line options, you can add various aspects of the + internal state to the output that is sent to the terminal. The + general format is + + + hb-shape [OPTIONS] + path/to/font/file.ttf + yourinputtext + + + The default output format is plain text (although JSON output + can be selected instead by specifying the option + --output-format=json). The default output + syntax reports each glyph name (or glyph index if there is no + name) followed by its cluster value, its horizontal and vertical + position displacement, and its horizontal and vertical advances. + + + Output options exist to skip any of these elements in the + output, and to include additional data, such as Unicode + code-point values, glyph extents, glyph flags, or interim + shaping results. + + + Output can also be redirected to a file, or input read from a + file.

+ +
+ hb-view + + hb-view allows you to + see the shaped output of an input string in rendered + form. Like hb-shape, + hb-view takes a font file and a text string + as its arguments: + + + hb-view [OPTIONS] + path/to/font/file.ttf + yourinputtext + + + By default, hb-view renders the shaped + text in ASCII block-character images as terminal output.

+ hb-subset + + hb-subset allows you + to generate a subset of a given font, with a limited set of + supported characters, features, and variation settings. + + + By default, you provide an input font and an input text string + as the arguments to hb-subset, and it will + generate a font that covers the input text exactly like the + input font does, but includes no other characters or features. + + + hb-subset [OPTIONS] + path/to/font/file.ttf + yourinputtext + + + For example, to create a subset of Noto Serif that just includes the + numerals and the lowercase Latin alphabet, you could run + + + hb-subset [OPTIONS] + NotoSerif-Regular.ttf + 0123456789abcdefghijklmnopqrstuvwxyz + + + There are options available to remove hinting from the + subsetted font and to specify a list of variation-axis settings. + +

+ +
+ Common data types and APIs + + HarfBuzz includes several APIs for working with general-purpose + data that you may find convenient to leverage in your own + software. They include set operations and integer-to-integer + mapping operations. + + + HarfBuzz uses set operations for internal bookkeeping, such as + when it collects all of the glyph IDs covered by a particular + font feature. You can also use the set API to build sets, add + and remove elements, test whether or not sets contain particular + elements, or compute the unions, intersections, or differences + between sets. + + + All set elements are integers (specifically, + hb_codepoint_t 32-bit unsigned ints), and there are + functions for fetching the minimum and maximum element from a + set. The set API also includes some functions that might not + be part of a generic set facility, such as the ability to add a + contiguous range of integer elements to a set in bulk, and the + ability to fetch the next-smallest or next-largest element. + + + The HarfBuzz set API includes some conveniences as well. All + sets are lifecycle-managed, just like other HarfBuzz + objects. You increase the reference count on a set with + hb_set_reference() and decrease it with + hb_set_destroy(). You can also attach + user data to a set, just like you can to blobs, buffers, faces, + fonts, and other objects, and set destroy callbacks. + + + HarfBuzz also provides an API for keeping track of + integer-to-integer mappings. As with the set API, each integer is + stored as an unsigned 32-bit hb_codepoint_t + element. Maps, like other objects, are reference counted with + reference and destroy functions, and you can attach user data to + them. The mapping operations include adding and deleting + integer-to-integer key:value pairs to the map, testing for the + presence of a key, fetching the population of the map, and so on. + + + There are several other internal HarfBuzz facilities that are + exposed publicly and which you may want to take advantage of + while processing text. HarfBuzz uses a common + hb_tag_t for a variety of OpenType tag identifiers (for + scripts, languages, font features, table names, variation-axis + names, and more), and provides functions for converting strings + to tags and vice-versa. + + + Finally, HarfBuzz also includes data type for Booleans, bit + masks, and other simple types. + +
+ +
+ UCDN + + HarfBuzz includes a copy of the UCDN (Unicode + Database and Normalization) library, which provides functions + for accessing basic Unicode character properties, performing + canonical composition, and performing both canonical and + compatibility decomposition. + + + Currently, UCDN supports direct queries for several more character + properties than HarfBuzz's built-in set of Unicode functions + does, such as the BiDirectional Class, East Asian Width, Paired + Bracket and Resolved Linebreak properties.

It runs on all major operating systems and software + platforms and it supports the major font formats in use + today. + +
+ What is text shaping? + + Text shaping is the process of translating a string of character + codes (such as Unicode codepoints) into a properly arranged + sequence of glyphs that can be rendered onto a screen or into + final output form for inclusion in a document. + + + The shaping process is dependent on the input string, the active + font, the script (or writing system) that the string is in, and + the language that the string is in. + + + Modern software systems generally only deal with strings in the + Unicode encoding scheme (although legacy systems and documents may + involve other encodings). + + + There are several font formats that a program might + encounter, each of which has a set of standard text-shaping + rules. + + The dominant format is OpenType. The + OpenType specification defines a series of shaping models for + various scripts from around the world. These shaping models depend on + the font incorporating certain features as + lookups in its GSUB + and GPOS tables. + + + Alternatively, OpenType fonts can include shaping features for + the Graphite shaping model. + + + TrueType fonts can also include OpenType shaping + features. Alternatively, TrueType fonts can also include Apple + Advanced Typography (AAT) tables to implement shaping + support. AAT fonts are generally only found on macOS and iOS systems. + + + Text strings will usually be tagged with a script and language + tag that provide the context needed to perform text shaping + correctly. The necessary script + and language + tags are defined by OpenType. + +
+ +
+ Why do I need a shaping engine? + + Text shaping is an integral part of preparing text for + display. Before a Unicode sequence can be rendered, the + codepoints in the sequence must be mapped to the corresponding + glyphs provided in the font, and those glyphs must be positioned + correctly relative to each other. For many of the scripts + supported in Unicode, these steps involve script-specific layout + rules, including complex joining, reordering, and positioning + behavior. Implementing these rules is the job of the shaping engine. + + + Text shaping is a fairly low-level operation. HarfBuzz is + used directly by text-handling libraries like Pango, as well as by the layout + engines in Firefox, LibreOffice, and Chromium. Unless you are + writing one of these layout engines + yourself, you will probably not need to use HarfBuzz: normally, + a layout engine, toolkit, or other library will turn text into + glyphs for you. + + + However, if you are writing a layout engine + or graphics library yourself, then you will need to perform text + shaping, and this is where HarfBuzz can help you. + + + Here are some specific scenarios where a text-shaping engine + like HarfBuzz helps you: + + + + + OpenType fonts contain a set of glyphs (that is, shapes + to represent the letters, numbers, punctuation marks, and + all other symbols), which are indexed by a glyph ID. + + + A particular glyph ID within the font does not necessarily + correlate to a predictable Unicode codepoint. For instance, + some fonts have the letter "a" as glyph ID 1, but + many others do not. In order to retrieve the right glyph + from the font to display "a", you need to consult + the table inside the font (the cmap + table) that maps Unicode codepoints to glyph IDs. In other + words, text shaping turns codepoints into glyph + IDs. + + + + + Many OpenType fonts contain ligatures: combinations of + characters that are rendered as a single unit. For instance, + it is common for the "f, i" letter + sequence to appear in print as the single ligature glyph + "fi". + + + Whether you should render an "f, i" sequence + as fi or as "fi" does not + depend on the input text. Instead, it depends on the whether + or not the font includes an "fi" glyph and on the + level of ligature application you wish to perform. The font + and the amount of ligature application used are under your + control. In other words, text shaping involves + querying the font's ligature tables and determining what + substitutions should be made. + + + + + While ligatures like "fi" are optional typographic + refinements, some languages require certain + substitutions to be made in order to display text correctly. + + + For example, in Tamil, when the letter "TTA" (ட) + letter is followed by the vowel sign "U" (ு), the pair + must be replaced by the single glyph "டு". The + sequence of Unicode characters "ட,ு" needs to be + substituted with a single "டு" glyph from the + font. + + + But "டு" does not have a Unicode codepoint. To + find this glyph, you need to consult the table inside + the font (the GSUB table) that contains + substitution information. In other words, text shaping + chooses the correct glyph for a sequence of characters + provided. + + + + + Similarly, each Arabic character has four different variants + corresponding to the different positions it might appear in + within a sequence. Inside a font, there will be separate + glyphs for the initial, medial, final, and isolated forms of + each letter, each at a different glyph ID. + + + Unicode only assigns one codepoint per character, so a + Unicode string will not tell you which glyph variant to use + for each character. To decide, you need to analyze the whole + string and determine the appropriate glyph for each character + based on its position. In other words, text + shaping chooses the correct form of the letter by its + position and returns the correct glyph from the font. + + + + + Other languages involve marks and accents that need to be + rendered in specific positions relative a base character. For + instance, the Moldovan language includes the Cyrillic letter + "zhe" (ж) with a breve accent, like so: "ӂ". + + + Some fonts will provide this character as a single + zhe-with-breve glyph, but other fonts will not and, instead, + will expect the rendering engine to form the character by + superimposing the separate "ж" and "˘" + glyphs. + + + But exactly where you should draw the breve depends on the + height and width of the preceding zhe glyph. To find the + right position, you need to consult the table inside + the font (the GPOS table) that contains + positioning information. + In other words, text shaping tells you whether you + have a precomposed glyph within your font or if you need to + compose a glyph yourself out of combining marks—and, + if so, where to position those marks. + + + + + If tasks like these are something that you need to do, then you + need a text shaping engine. You could use Uniscribe if you are + writing Windows software; you could use CoreText on macOS; or + you could use HarfBuzz. + + + + In the rest of this manual, the text will assume that the reader + is that implementor of a text-layout engine. + + +
+ + +
+ What does HarfBuzz do? + + HarfBuzz provides text shaping through a cross-platform + C API that accepts sequences of Unicode codepoints as input. Currently, + the following OpenType shaping models are supported: + + + + + Indic (covering Devanagari, Bengali, Gujarati, + Gurmukhi, Kannada, Malayalam, Oriya, Tamil, Telugu, and + Sinhala) + + + + + Arabic (covering Arabic, N'Ko, Syriac, and Mongolian) + + + + + Thai and Lao + + + + + Khmer + + + + + Myanmar + + + + + + Tibetan + + + + + + Hangul + + + + + + Hebrew + + + + + The Universal Shaping Engine or USE + (covering complex scripts not covered by the above shaping + models) + + + + + A default shaping model for non-complex scripts + (covering Latin, Cyrillic, Greek, Armenian, Georgian, Tifinagh, + and many others) + + + + + Emoji (including emoji modifier sequences, flag sequences, + and ZWJ sequences) + + + + + + In addition to OpenType shaping, HarfBuzz supports the latest + version of Graphite shaping (the "Graphite 2" model) and AAT + shaping. + + + + HarfBuzz can read and understand TrueType fonts (.ttf), TrueType + collections (.ttc), and OpenType fonts (.otf, including those + fonts that contain TrueType-style outlines and those that + contain PostScript CFF or CFF2 outlines). + + + + HarfBuzz is designed and tested to run on top of the FreeType + font renderer. It can run on Linux, Android, Windows, macOS, and + iOS systems. + + + + In addition to its core shaping functionality, HarfBuzz provides + functions for accessing other font features, including optional + GSUB and GPOS OpenType features, as well as + all color-font formats (CBDT, + sbix, COLR/CPAL, and + SVG-OT) and OpenType variable fonts. HarfBuzz + also includes a font-subsetting feature. HarfBuzz can perform + some low-level math-shaping operations, although it does not + currently perform full shaping for mathematical typesetting. + + + + A suite of command-line utilities is also provided in the + source-code tree, designed to help users test and debug + HarfBuzz's features on real-world fonts and input. + +
+ +
+ What HarfBuzz doesn't do + + HarfBuzz will take a Unicode string, shape it, and give you the + information required to lay it out correctly on a single + horizontal (or vertical) line using the font provided. That is the + extent of HarfBuzz's responsibility. + + + It is important to note that if you are implementing a complete + text-layout engine you may have other responsibilities that + HarfBuzz will not help you with. For example: + + + + + HarfBuzz won't help you with bidirectionality. If you want to + lay out text that includes a mix of Hebrew and English, you + will need to ensure that each buffer provided to HarfBuzz + has all of its characters in the same order and that the + directionality of the buffer is set correctly. This may mean + segmenting the text before it is placed into HarfBuzz buffers. In + other words, the user will hit the keys in the following + sequence: + + + A B C [space] ג ב א [space] D E F + + + but will expect to see in the output: + + + ABC אבג DEF + + + This reordering is called bidi processing + ("bidi" is short for bidirectional), and there's an + algorithm as an annex to the Unicode Standard which tells you how + to process a string of mixed directionality. + Before sending your string to HarfBuzz, you may need to apply the + bidi algorithm to it. Libraries such as ICU and fribidi can do this for you. + + + + + HarfBuzz won't help you with text that contains different font + properties. For instance, if you have the string "a + huge breakfast", and you expect + "huge" to be italic, then you will need to send three + strings to HarfBuzz: a, in your Roman font; + huge using your italic font; and + breakfast using your Roman font again. + + + Similarly, if you change the font, font size, script, + language, or direction within your string, then you will + need to shape each run independently and output them + independently. HarfBuzz expects to shape a run of characters + that all share the same properties. + + + + + HarfBuzz won't help you with line breaking, hyphenation, or + justification. As mentioned above, HarfBuzz lays out the string + along a single line of, notionally, + infinite length. If you want to find out where the potential + word, sentence and line break points are in your text, you + could use the ICU library's break iterator functions. + + + HarfBuzz can tell you how wide a shaped piece of text is, which is + useful input to a justification algorithm, but it knows nothing + about paragraphs, lines or line lengths. Nor will it adjust the + space between words to fit them proportionally into a line. + + + + + As a layout-engine implementor, HarfBuzz will help you with the + interface between your text and your font, and that's something + that you'll need—what you then do with the glyphs that your font + returns is up to you. + +
+ +
+ Why is it called HarfBuzz? + + HarfBuzz began its life as text-shaping code within the FreeType + project (and you will see references to the FreeType authors + within the source code copyright declarations), but was then + extracted out to its own project. This project is maintained by + Behdad Esfahbod, who named it HarfBuzz. Originally, it was a + shaping engine for OpenType fonts—"HarfBuzz" is + the Persian for "open type". + +

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.
