Changes in version 1.17:
Changes in version 1.21:
The new functions 'parsed_name' (C++) and 'ap_parsed_name' (C) have been
added. They return the full name of the option parsed (short or long) to
help produce more accurate diagnostic messages.
The last argument of the C++ constructor and of the C function 'ap_init' has
been changed from 'bool in_order' to 'int flags'. This change is
backwards-compatible after recompilation because the default value of both
arguments is 0, and the new flag 'in_order' has a value of 1. So the old
'in_order = true' is equivalent to the new 'flags = in_order'.
The C++ constructor and the C function 'ap_init' have been extended with the
flag 'in_order_stop' to parse the first non-option argument and all the
arguments following it as non-option arguments, even if they begin with a
hyphen. This is similar to the POSIX function 'getopt', which stops option
processing after finding the first non-option argument.
The C++ constructor and the C function 'ap_init' have been extended with the
flag 'in_order_skip' to parse only the heading options, skipping the first
non-option argument and all the arguments following it. This mode is useful
for parsing the command line of programs that invoke other programs, like
'timeout', 'xargs', or 'valgrind'.
The C++ constructor and the C function 'ap_init' have been extended with the
flag 'neg_non_opt' to parse negative numbers as non-option arguments without
reordering them. This mode is useful for parsing the command line of tools
like 'seq' which take negative numbers as arguments. (Suggested by Mohammad
Akhlaghi):
$ arg_parser +15 -Inf 0 -20 -a -.5 -v
option '-a'
option '-v'
non-option argument '+15'
non-option argument '-Inf'
non-option argument '0'
non-option argument '-20'
non-option argument '-.5'
The 'enum Has_arg' value 'yme' has been renamed to 'yesme'.
The code of the C version has been reorganized.
The new section 'Differences with getopt and getopt_long' has been added to
the manual.

Description
Arg_parser is an argument parser that follows POSIX and GNU conventions for
command line arguments. There exist C++ and C versions of Arg_parser. The
command-line arguments. There exist C++ and C versions of Arg_parser. The
C++ version is implemented as a C++ class, while the C version is
implemented as a single struct plus associated functions. Both are simpler,
easier to use, and safer than 'getopt_long'.
For maximum stability, Arg_parser is self-contained. It extracts all the
information it needs from its arguments to avoid refering to them later.
This avoids index-out-of-bounds errors.
information it needs from its arguments to avoid referring to them later.
This avoids index-out-of-bounds errors and allows the parser object to be
passed as argument to other functions for further analysis.
Arg_parser does not modify its arguments, nor uses any global variables. So
you may create more than one parser in your program if you need or want to.
Arg_parser does not modify its arguments (argc, argv), nor uses any global
variables.
The C++ version of Arg_parser can also parse options from configuration
files.
To use Arg_parser in your own programs simply copy the files 'arg_parser.h'
and 'arg_parser.cc' (or 'carg_parser.h' and 'carg_parser.c' for the
C version) in your source tree. See the file 'main.cc' ('cmain.c') for an
example of use.
The C++ version of Arg_parser is provided in the files 'arg_parser.h' and
'arg_parser.cc'. To learn how to use Arg_parser in your C++ programs, see
the C++ example in the manual and the example file 'main.cc' in the source
tarball.
The C version of Arg_parser is provided in the files 'carg_parser.h' and
'carg_parser.c'. To learn how to use Arg_parser in your C programs, see the
C example in the manual and the example file 'cmain.c' in the source
tarball.
Arg_parser was developed as the argument parser for GNU moe, because moe's
argument parsing is rather complex. Then I used it in my other projects,

Arg_parser was developed as the argument parser for GNU moe, because
moe's argument parsing is rather complex. Then I used it in my other
projects, including GNU ddrescue, GNU ed, lzip, GNU ocrad, tarlz, and
zutils, with excellent results.

1.1 Differences with 'getopt' and 'getopt_long'.
================================================
'getopt' parses the options one by one, which requires internal state. Part
of this state is stored in several global variables, and part of it is
hidden. For example, the POSIX specification of 'getopt' states that:
When an element of argv[] contains multiple option characters, it is
unspecified how getopt() determines which options have already been
processed.
Parsing the options one by one is also a lot of work for the application,
which must check for errors (invalid option, missing option argument, etc)
for each option. 'getopt' is the 1970s way of parsing command-line
arguments.
'getopt_long' is a not-very-well-designed extension on top of 'getopt'. In
addition to parsing the options one by one as 'getopt' does, 'getopt_long'
accepts configuration data from two overlapping sources, which makes it
easy for errors in the configuration to remain undetected. For example, a
certain long option can be declared to be equivalent to a given short
option, but both forms of the option may contain contradictory requirements
for the option's argument.
OTOH, Arg_parser parses the whole command line at once and fills a struct
with the results, like 'gmtime_r' and 'stat' do. This way, errors are
checked once, there is no need to permute the elements of argv, and the
struct returned can be used undisturbed by later changes in argv.
Finally, using Arg_parser instead of 'getopt_long' reduces the size of your
source code because, as 'getopt_long' is not available on all systems, a
portable program using it needs to ship its (larger) source anyway.

2 Syntax of command line arguments
2 Syntax of command-line arguments
**********************************
POSIX recommends these conventions for command line arguments. Arg_parser
POSIX recommends these conventions for command-line arguments. Arg_parser
makes it easy to implement them.
* A command line argument is an option if it begins with a hyphen
delimiter ('-').
* Multiple options may follow a hyphen delimiter in a single token if
the options don't take arguments. Thus, '-abc' is equivalent to
'-a -b -c'.
* A command-line argument is an option if it begins with a hyphen ('-').
* Option names are single alphanumeric characters.
* Certain options require an argument.
* An option and its argument may or may not appear as separate tokens.
(In other words, the whitespace separating them is optional). Thus,
'-o foo' and '-ofoo' are equivalent.
(In other words, the whitespace separating them is optional, unless the
argument is the empty string). Thus, '-o foo' and '-ofoo' are
equivalent.
* One or more options without arguments, followed by at most one option
that takes an argument, may follow a hyphen in a single token. Thus,
'-abc' is equivalent to '-a -b -c'.
* Options typically precede other non-option arguments.
Arg_parser normally makes it appear as if all the option arguments were
Arg_parser normally makes it appear as if all the options were
specified before all the non-option arguments for the purposes of
parsing, even if the user of your program intermixed option and
parsing, even if the user of your program intermixed options and
non-option arguments. If you want the arguments in the exact order the
user typed them, call 'Arg_parser' with IN_ORDER = true.
user typed them, call 'Arg_parser' with FLAGS = 'in_order'.
* The argument '--' terminates all options; any following arguments are
treated as non-option arguments, even if they begin with a hyphen.
* A token consisting of a single hyphen character is interpreted as an
ordinary non-option argument. By convention, it is used to specify
input from or output to the standard input and output streams.
standard input, standard output, or a file named '-'.
* Options may be supplied in any order, or appear multiple times. The
interpretation is left up to the particular application program.
* GNU adds "long options" to these conventions. Long options consist of
'--' followed by a name made of alphanumeric characters and hyphens.
Option names are typically one to three words long, with hyphens to
separate words. Users can abbreviate the option names as long as the
abbreviations are unique.
GNU adds "long options" to these conventions:
* A long option consists of two hyphens ('--') followed by a name made
of alphanumeric characters and hyphens. Option names are typically one
to three words long, with hyphens to separate words. Abbreviations can
be used for the long option names as long as the abbreviations are
unique.
* A long option and its argument may or may not appear as separate
tokens. In the latter case they must be separated by an equal sign '='.
Thus, '--foo bar' and '--foo=bar' are equivalent.
* The syntax for optional option arguments is
'-<short_option><argument>' (without whitespace), or
'--<long_option>=<argument>'.
The syntax of options with an optional argument is
'-<short_option><argument>' (without whitespace), or
'--<long_option>=<argument>'.
The syntax of options with an empty argument is '-<short_option> ""',
'--<long_option> ""', or '--<long_option>=""'.

****************************************
3 Using the C++ version of Arg_parser
*************************************
To use Arg_parser in your own programs first copy the files 'arg_parser.h'
and 'arg_parser.cc' in your source tree. See the file 'main.cc' for an
example of use.
The C++ version of Arg_parser is provided in the files 'arg_parser.h' and

==========================================

arguments from ARGV, and the other to parse a single token from a
configuration file or other source.

which is zero. 'struct Option' has the following members:
'struct Option' has the following members:
'int code'
-- Member: 'int' code
This member is the code that identifies the option, normally the
short-option character. Must be different from 0. A code value
outside the unsigned char range means a long-only option.
'const char * long_name'
-- Member: 'const char *' long_name
This member is the long option name. It is a zero-terminated
string. A null or empty long_name means a short-only option.
'enum Has_arg has_arg'
-- Member: 'enum Has_arg' has_arg
This member says whether the option takes an argument. It has
three valid values: 'no', 'yes', and 'maybe'.
four valid values: 'no', 'yes', 'maybe', and 'yesme', meaning
respectively 'no argument', 'non-empty argument required',
'optional argument', and 'argument required, but it may be the
empty string'. 'yesme' is not recommended.
If an empty argument is passed to an option specified as 'yesme',
it must be in a separate command-line argument or specified as a
long option with the empty string after the '=' character. It
can't be specified as the empty string after the short option.
-- Data Type: enum Flags
The argument FLAGS is a bit mask. You can bitwise-OR the following
constants and assign them to FLAGS to modify the way in which the
arguments are parsed. FLAGS = 0 chooses the default behavior (reorder
the options to put them before the non-option arguments).
-- Constant: 'Flags' in_order
Store the arguments in the exact order the user typed them,
without reordering the options to put them before the non-option
arguments.
-- Constant: 'Flags' in_order_stop
Stop option processing when finding the first non-option argument
as if the argument '--' had been found before it. Store the first
non-option argument and all the arguments following it as
non-option arguments, even if they begin with a hyphen. This is
similar to the POSIX function 'getopt', which stops option
processing after finding the first non-option argument.
-- Constant: 'Flags' in_order_skip
Parse only the heading options. Skip the first non-option
argument and all the arguments following it; do not parse nor
store them. The function 'argv_index' returns the index in ARGV
of the first argument skipped (the first non-option argument), or
ARGC if no arguments were skipped. This mode is useful for
parsing the command line of programs that invoke other programs,
like 'timeout', 'xargs', or 'valgrind'.
-- Constant: 'Flags' neg_non_opt
Parse the negative numbers, including '-inf', '-Inf', and '-INF',
as non-option arguments without reordering them. Numbers start
with a digit or a period and a digit. This mode is useful for
parsing the command line of tools like 'seq' which take negative
numbers as arguments.

5 Tutorial for the C++ version
******************************
This tutorial uses lzip as an example of how to use Arg_parser in a C++
program. You need to follow these 6 steps:
First copy the files 'arg_parser.h' and 'arg_parser.cc' in your source
tree, in the same directory as the file containing the function 'main' of
your program. In lzip, 'main' is in 'main.cc'.
Second, include these header files near the top of 'main.cc':
#include <string>
#include <vector>
#include "arg_parser.h"
Third, define inside 'main' the option names and argument requirements.
Lzip defines the following options:
const Arg_parser::Option options[] = {
{ '0', "fast", Arg_parser::no },
{ '1', 0, Arg_parser::no },
{ '2', 0, Arg_parser::no },
{ '3', 0, Arg_parser::no },
{ '4', 0, Arg_parser::no },
{ '5', 0, Arg_parser::no },
{ '6', 0, Arg_parser::no },
{ '7', 0, Arg_parser::no },
{ '8', 0, Arg_parser::no },
{ '9', "best", Arg_parser::no },
{ 'a', "trailing-error", Arg_parser::no },
{ 'b', "member-size", Arg_parser::yes },
{ 'c', "stdout", Arg_parser::no },
{ 'd', "decompress", Arg_parser::no },
{ 'f', "force", Arg_parser::no },
{ 'F', "recompress", Arg_parser::no },
{ 'h', "help", Arg_parser::no },
{ 'k', "keep", Arg_parser::no },
{ 'l', "list", Arg_parser::no },
{ 'm', "match-length", Arg_parser::yes },
{ 'n', "threads", Arg_parser::yes },
{ 'o', "output", Arg_parser::yes },
{ 'q', "quiet", Arg_parser::no },
{ 's', "dictionary-size", Arg_parser::yes },
{ 'S', "volume-size", Arg_parser::yes },
{ 't', "test", Arg_parser::no },
{ 'v', "verbose", Arg_parser::no },
{ 'V', "version", Arg_parser::no },
{ opt_lt, "loose-trailing", Arg_parser::no },
{ 0, 0, Arg_parser::no } };
Fourth, declare and initialize the parser:
const Arg_parser parser( argc, argv, options );
if( parser.error().size() ) // bad option
{ show_error( parser.error().c_str(), 0, true ); return 1; }
Fifth, perform the actions corresponding to each option parsed. Lzip
performs the following actions:
int argind = 0;
for( ; argind < parser.arguments(); ++argind )
{
const int code = parser.code( argind );
if( !code ) break; // no more options
const char * const pn = parser.parsed_name( argind ).c_str();
const std::string & sarg = parser.argument( argind );
const char * const arg = sarg.c_str();

case '6': case '7': case '8': case '9': zero = code == '0';

case 'a': cl_opts.ignore_trailing = false; break;
case 'b': member_size = getnum(arg, pn, 100000, max_member_size); break;
case 'c': to_stdout = true; break;
case 'd': set_mode( program_mode, m_decompress ); break;
case 'f': force = true; break;
case 'F': recompress = true; break;
case 'h': show_help(); return 0;
case 'k': keep_input_files = true; break;
case 'l': set_mode( program_mode, m_list ); break;
case 'm': encoder_options.match_len_limit =
getnum( arg, pn, min_match_len_limit, max_match_len );
zero = false; break;
case 'n': break; // ignored
case 'o': if( sarg == "-" ) to_stdout = true;
else { default_output_filename = sarg; } break;
case 'q': verbosity = -1; break;
case 's': encoder_options.dictionary_size = get_dict_size( arg, pn );
zero = false; break;
case 'S': volume_size = getnum(arg, pn, 100000, max_volume_size); break;
case 't': set_mode( program_mode, m_test ); break;
case 'v': if( verbosity < 4 ) ++verbosity; break;
case 'V': show_version(); return 0;
case opt_lt: cl_opts.loose_trailing = true; break;
default: internal_error( "uncaught option." );
}
} // end process options
Sixth, process any remaining non-option arguments (file names in the case of
lzip):
std::vector< std::string > filenames;
bool filenames_given = false;
for( ; argind < parser.arguments(); ++argind )
{
filenames.push_back( parser.argument( argind ) );
if( filenames.back() != "-" ) filenames_given = true;
}
if( filenames.empty() ) filenames.push_back("-");
// do something with 'filenames'

6 Tutorial for the C version
****************************
This tutorial uses GNU ed as an example of how to use Arg_parser in a C

your program. In GNU ed, 'main' is in 'main.c'.
Second, include the header 'carg_parser.h' near the top of 'main.c':
#include "carg_parser.h"
Third, define inside 'main' the option names and argument requirements. Ed
defines the following options:
const ap_Option options[] = {

{ 'V', "version", ap_no },
{ opt_cr, "strip-trailing-cr", ap_no },
{ opt_un, "unsafe-names", ap_no },
{ 0, 0, ap_no } };
Fourth, declare and initialize the parser:

{ show_error( "Memory exhausted.", 0, false ); return 1; }
if( ap_error( &parser ) ) /* bad option */
{ show_error( ap_error( &parser ), 0, true ); return 1; }
Fifth, perform the actions corresponding to each option parsed. Ed performs
the following actions:

for( ; argind < ap_arguments( &parser ); ++argind )
{
const int code = ap_code( &parser, argind );

case opt_un: safe_names = false; break;
default: show_error( "internal error: uncaught option.", 0, false );
return 3;
}
} /* end process options */
Sixth, process any remaining non-option arguments (line number and file
name in the case of ed):
for( ; argind < ap_arguments( &parser ); ++argind )
{
const char * const arg = ap_argument( &parser, argind );
/* do something with 'arg' */

@section Differences with @samp{getopt} and @samp{getopt_long}.
@samp{getopt} parses the options one by one, which requires internal state.
Part of this state is stored in several global variables, and part of it is
hidden. For example, the POSIX specification of @samp{getopt} states that:
@quotation
When an element of argv[] contains multiple option characters, it is
unspecified how getopt() determines which options have already been
processed.
@end quotation
Parsing the options one by one is also a lot of work for the application,
which must check for errors (invalid option, missing option argument, etc)
for each option. @samp{getopt} is the 1970s way of parsing command-line
arguments.
@samp{getopt_long} is a not-very-well-designed extension on top of
@samp{getopt}. In addition to parsing the options one by one as
@samp{getopt} does, @samp{getopt_long} accepts configuration data from two
overlapping sources, which makes it easy for errors in the configuration to
remain undetected. For example, a certain long option can be declared to be
equivalent to a given short option, but both forms of the option may contain
contradictory requirements for the option's argument.
OTOH, Arg_parser parses the whole command line at once and fills a struct
with the results, like @samp{gmtime_r} and @samp{stat} do. This way, errors
are checked once, there is no need to permute the elements of argv, and the
struct returned can be used undisturbed by later changes in argv.
Finally, using Arg_parser instead of @samp{getopt_long} reduces the size of
your source code because, as @samp{getopt_long} is not available on all
systems, a portable program using it needs to ship its (larger) source
anyway.

POSIX recommends these conventions for command-line arguments.
Arg_parser makes it easy to implement them.
@itemize @bullet
@item A command line argument is an option if it begins with a hyphen
delimiter (@samp{-}).
@item Multiple options may follow a hyphen delimiter in a single token
if the options don't take arguments. Thus, @samp{-abc} is equivalent to
@w{@samp{-a -b -c}}.
@item A command-line argument is an option if it begins with a hyphen
(@samp{-}).
@item Option names are single alphanumeric characters.
@item Certain options require an argument.
@item An option and its argument may or may not appear as separate
tokens. (In other words, the whitespace separating them is optional).
Thus, @w{@samp{-o foo}} and @samp{-ofoo} are equivalent.
@item An option and its argument may or may not appear as separate tokens.
(In other words, the whitespace separating them is optional, unless the
argument is the empty string).
Thus, @w{@option{-o foo}} and @option{-ofoo} are equivalent.
@item One or more options without arguments, followed by at most one option
that takes an argument, may follow a hyphen in a single token.
Thus, @option{-abc} is equivalent to @w{@option{-a -b -c}}.
@item Options typically precede other non-option arguments.
Arg_parser normally makes it appear as if all the option arguments were
specified before all the non-option arguments for the purposes of parsing,
even if the user of your program intermixed option and non-option arguments.
If you want the arguments in the exact order the user typed them, call
@samp{Arg_parser} with @w{@var{in_order} = true}.

@item GNU adds @dfn{long options} to these conventions. Long options
consist of @samp{--} followed by a name made of alphanumeric characters

hyphens to separate words. Users can abbreviate the option names as long
as the abbreviations are unique.

@section Parsing arguments and reporting errors
The class @samp{Arg_parser} has two constructors; one to parse command-line
arguments from @var{argv}, and the other to parse a single token from a
configuration file or other source.
@anchor{struct Option}
@deffn {Data Type} struct Option
This structure describes a single option for the sake of
@samp{Arg_parser}. The argument @var{options} must be an array of these
structures, one for each option. Terminate the array with an element
containing a code which is zero.
@deftp {Data Type} struct Option
This structure describes a single option for the sake of @samp{Arg_parser}.
The argument @var{options} must be an array of these structures, one for
each option. Terminate the array with an element containing a code which is
zero. @samp{struct Option} has the following members:
@samp{struct Option} has the following members:
@table @code
@item int code
@deftypevr Member @code{int} code
This member is the code that identifies the option, normally the
short-option character. Must be different from 0. A code value outside
the unsigned char range means a long-only option.
short-option character. Must be different from 0. A code value outside the
unsigned char range means a long-only option.
@end deftypevr
@item const char * long_name
This member is the long option name. It is a zero-terminated string. A
null or empty long_name means a short-only option.
@deftypevr Member @code{const char *} long_name
This member is the long option name. It is a zero-terminated string. A null
or empty long_name means a short-only option.
@end deftypevr
@item enum Has_arg has_arg
This member says whether the option takes an argument. It has three
valid values: @samp{no}, @samp{yes}, and @samp{maybe}.
@end table
@end deffn
@deftypevr Member @code{enum Has_arg} has_arg
This member says whether the option takes an argument. It has four valid
values: @samp{no}, @samp{yes}, @samp{maybe}, and @samp{yesme}, meaning
respectively @samp{no argument}, @samp{non-empty argument required},
@samp{optional argument}, and @samp{argument required, but it may be the
empty string}. @samp{yesme} is not recommended.
@defun Arg_parser ( const int @var{argc}, const char * const @var{argv}[], const Option @var{options}[], const bool @var{in_order} = false )
If an empty argument is passed to an option specified as @samp{yesme}, it
must be in a separate command-line argument or specified as a long option
with the empty string after the @samp{=} character. It can't be specified as
the empty string after the short option.
@end deftypevr
@end deftp
@anchor{enum Flags}
@deftp {Data Type} enum Flags
The argument @var{flags} is a bit mask. You can bitwise-OR the following
constants and assign them to @var{flags} to modify the way in which the
arguments are parsed. @w{@var{flags} = 0} chooses the default behavior
(reorder the options to put them before the non-option arguments).
@deftypevr Constant @code{Flags} in_order
Store the arguments in the exact order the user typed them, without
reordering the options to put them before the non-option arguments.
@end deftypevr
@deftypevr Constant @code{Flags} in_order_stop
Stop option processing when finding the first non-option argument as if the
argument @samp{--} had been found before it. Store the first non-option
argument and all the arguments following it as non-option arguments, even if
they begin with a hyphen. This is similar to the POSIX function @samp{getopt},
which stops option processing after finding the first non-option argument.
@end deftypevr
@deftypevr Constant @code{Flags} in_order_skip
Parse only the heading options. Skip the first non-option argument and all
the arguments following it; do not parse nor store them. The function
@samp{argv_index} returns the index in @var{argv} of the first argument
skipped (the first non-option argument), or @var{argc} if no arguments were
skipped. This mode is useful for parsing the command line of programs that
invoke other programs, like @command{timeout}, @command{xargs}, or
@command{valgrind}.
@end deftypevr
@deftypevr Constant @code{Flags} neg_non_opt
Parse the negative numbers, including @samp{-inf}, @samp{-Inf}, and
@samp{-INF}, as non-option arguments without reordering them. Numbers start
with a digit or a period and a digit. This mode is useful for parsing the
command line of tools like @command{seq} which take negative numbers as
arguments.
@end deftypevr
@end deftp
@defun Arg_parser ( const int @var{argc}, const char * const @var{argv}[], const Option @var{options}[], const int @var{flags} = 0 )
Constructor. Reads the arguments in @var{argv} and parses all options,
option arguments, and non-option arguments contained in them. In case of

@defun Arg_parser ( const char * const @var{opt}, const char * const @var{arg}, const Option @var{options}[] )
Restricted constructor. Parses a single token (plus an optional second
token in case an argument is needed for an option parsed). Can be used to
parse options from a configuration file one at a time. Be warned that a
single token may produce an undefined number of short options. In case
of error, @samp{error().size()} will be non-zero.

@chapter Tutorial for the C++ version
@cindex C++ example
This tutorial uses @uref{http://www.nongnu.org/lzip/lzip.html,,lzip} as an
example of how to use Arg_parser in a C++ program. You need to follow these
6 steps:
First copy the files @file{arg_parser.h} and @file{arg_parser.cc} in your
source tree, in the same directory as the file containing the function
@samp{main} of your program. In lzip, @samp{main} is in @file{main.cc}.
Second, include these header files near the top of @file{main.cc}:
@verbatim
#include <string>
#include <vector>
#include "arg_parser.h"
@end verbatim
Third, define inside @samp{main} the option names and argument requirements.
Lzip defines the following options:
@verbatim
const Arg_parser::Option options[] = {
{ '0', "fast", Arg_parser::no },
{ '1', 0, Arg_parser::no },
{ '2', 0, Arg_parser::no },
{ '3', 0, Arg_parser::no },
{ '4', 0, Arg_parser::no },
{ '5', 0, Arg_parser::no },
{ '6', 0, Arg_parser::no },
{ '7', 0, Arg_parser::no },
{ '8', 0, Arg_parser::no },
{ '9', "best", Arg_parser::no },
{ 'a', "trailing-error", Arg_parser::no },
{ 'b', "member-size", Arg_parser::yes },
{ 'c', "stdout", Arg_parser::no },
{ 'd', "decompress", Arg_parser::no },
{ 'f', "force", Arg_parser::no },
{ 'F', "recompress", Arg_parser::no },
{ 'h', "help", Arg_parser::no },
{ 'k', "keep", Arg_parser::no },
{ 'l', "list", Arg_parser::no },
{ 'm', "match-length", Arg_parser::yes },
{ 'n', "threads", Arg_parser::yes },
{ 'o', "output", Arg_parser::yes },
{ 'q', "quiet", Arg_parser::no },
{ 's', "dictionary-size", Arg_parser::yes },
{ 'S', "volume-size", Arg_parser::yes },
{ 't', "test", Arg_parser::no },
{ 'v', "verbose", Arg_parser::no },
{ 'V', "version", Arg_parser::no },
{ opt_lt, "loose-trailing", Arg_parser::no },
{ 0, 0, Arg_parser::no } };
@end verbatim
Fourth, declare and initialize the parser:
@verbatim
const Arg_parser parser( argc, argv, options );
if( parser.error().size() ) // bad option
{ show_error( parser.error().c_str(), 0, true ); return 1; }
@end verbatim
Fifth, perform the actions corresponding to each option parsed. Lzip
performs the following actions:
@verbatim
int argind = 0;
for( ; argind < parser.arguments(); ++argind )
{
const int code = parser.code( argind );
if( !code ) break; // no more options
const char * const pn = parser.parsed_name( argind ).c_str();
const std::string & sarg = parser.argument( argind );
const char * const arg = sarg.c_str();
switch( code )
{
case '0': case '1': case '2': case '3': case '4': case '5':
case '6': case '7': case '8': case '9': zero = code == '0';
encoder_options = option_mapping[code-'0']; break;
case 'a': cl_opts.ignore_trailing = false; break;
case 'b': member_size = getnum(arg, pn, 100000, max_member_size); break;
case 'c': to_stdout = true; break;
case 'd': set_mode( program_mode, m_decompress ); break;
case 'f': force = true; break;
case 'F': recompress = true; break;
case 'h': show_help(); return 0;
case 'k': keep_input_files = true; break;
case 'l': set_mode( program_mode, m_list ); break;
case 'm': encoder_options.match_len_limit =
getnum( arg, pn, min_match_len_limit, max_match_len );
zero = false; break;
case 'n': break; // ignored
case 'o': if( sarg == "-" ) to_stdout = true;
else { default_output_filename = sarg; } break;
case 'q': verbosity = -1; break;
case 's': encoder_options.dictionary_size = get_dict_size( arg, pn );
zero = false; break;
case 'S': volume_size = getnum(arg, pn, 100000, max_volume_size); break;
case 't': set_mode( program_mode, m_test ); break;
case 'v': if( verbosity < 4 ) ++verbosity; break;
case 'V': show_version(); return 0;
case opt_lt: cl_opts.loose_trailing = true; break;
default: internal_error( "uncaught option." );
}
} // end process options
@end verbatim
Sixth, process any remaining non-option arguments (file names in the case of
lzip):
@verbatim
std::vector< std::string > filenames;
bool filenames_given = false;
for( ; argind < parser.arguments(); ++argind )
{
filenames.push_back( parser.argument( argind ) );
if( filenames.back() != "-" ) filenames_given = true;
}
if( filenames.empty() ) filenames.push_back("-");
// do something with 'filenames'
@end verbatim

Fourth, declare and initialize the parser:
@verbatim
Arg_parser parser;
if( !ap_init( &parser, argc, argv, options, 0 ) )
{ show_error( "Memory exhausted.", 0, false ); return 1; }
if( ap_error( &parser ) ) /* bad option */
{ show_error( ap_error( &parser ), 0, true ); return 1; }
@end verbatim
Fifth, perform the actions corresponding to each option parsed. Ed performs
the following actions:
@verbatim
int argind = 0;
for( ; argind < ap_arguments( &parser ); ++argind )
{
const int code = ap_code( &parser, argind );
if( !code ) break; /* no more options */
const char * const arg = ap_argument( &parser, argind );
switch( code )
{
case 'E': extended_regexp_ = true; break;
case 'G': traditional_ = true; break; /* backward compatibility */
case 'h': show_help(); return 0;
case 'l': loose = true; break;
case 'p': if( set_prompt( arg ) ) break; else return 1;
case 'q': quiet = true; break;
case 'r': restricted_ = true; break;
case 's': scripted_ = true; break;
case 'v': set_verbose(); break;
case 'V': show_version(); return 0;
case opt_cr: strip_cr_ = true; break;
case opt_un: safe_names = false; break;
default: show_error( "internal error: uncaught option.", 0, false );
return 3;
}
} /* end process options */
@end verbatim
Sixth, process any remaining non-option arguments (line number and file
name in the case of ed):
@verbatim
for( ; argind < ap_arguments( &parser ); ++argind )
{
const char * const arg = ap_argument( &parser, argind );
/* do something with 'arg' */
}
@end verbatim

Arg_parser \- POSIX/GNU command line argument parser. (C version)
Arg_parser \- POSIX/GNU command\-line argument parser. (C version)
.PP
Arg_parser is an argument parser that follows POSIX and GNU conventions for
command line arguments. There exist C++ and C versions of Arg_parser. The
command\-line arguments. There exist C++ and C versions of Arg_parser. The
C++ version is implemented as a C++ class, while the C version is
implemented as a single struct plus associated functions. Both are simpler,
easier to use, and safer than 'getopt_long'.
.PP
For maximum stability, Arg_parser is self\-contained. It extracts all the
information it needs from its arguments to avoid refering to them later.
This avoids index\-out\-of\-bounds errors.
information it needs from its arguments to avoid referring to them later.
This avoids index\-out\-of\-bounds errors and allows the parser object to be
passed as argument to other functions for further analysis.
.PP
Arg_parser does not modify its arguments, nor uses any global variables. So
you may create more than one parser in your program if you need or want to.
Arg_parser does not modify its arguments (argc, argv), nor uses any global
variables.
.PP
The C++ version of Arg_parser can also parse options from configuration
files.
.PP
To use Arg_parser in your own programs simply copy the files 'carg_parser.h'
and 'carg_parser.c' in your source tree. See the file 'cmain.c' for an
example of use.
The C version of Arg_parser is provided in the files 'carg_parser.h' and
\&'carg_parser.c'. To learn how to use Arg_parser in your C programs, see the
C example in the manual and the example file 'cmain.c' in the source
tarball.

<dt><strong>Copas 4.7.x</strong> [unreleased]</dt>
<dt><strong>Copas 4.12.0</strong> [15/Aug/2026]</dt>
<dd><ul>
<li>Fix: a 0-byte <code>receive(0)</code> on a TCP/SSL socket was treated like a normal
read and queued the caller on <code>select</code>, blocking until more data arrived even
though nothing was needed. Per POSIX, a 0-byte read on a stream socket is a no-op; it now
returns <code>""</code> immediately (#223).</li>
<li>Fix: <code>copas.http</code> included the URL fragment in the request line sent to
the origin server (and, in proxy mode, to the proxy). Fragments are client-side only and
must never be transmitted on the wire; a fragment containing sensitive data (e.g. an OAuth
callback token) was disclosed to the server and to proxy infrastructure/logs (#220).</li>
<li>Fix: <code>sock:dohandshake()</code> returned <code>nil + err</code> on a handshake
timeout instead of throwing like every other failure path. A
timed-out handshake could leave a connection running without the intended TLS
configuration instead of aborting it; it now throws consistently on a failure (#189).</li>
<li>Fix: <code>copas.http</code> reused the SNI server name from the first request of a
redirect chain for every subsequent hop, so a redirect to a different host still sent the
original host's name in the TLS handshake instead of the new target's. This also applied
to an explicitly caller-supplied SNI name, which is now cleared on redirect so it no longer
follows the chain to unrelated hosts.</li>
<li>Fix: <code>copas.http</code> sent a redirect target's literal IP address as the TLS
SNI name when no hostname was available. IP literals are not valid SNI names per RFC 6066;
the SNI extension is now omitted entirely for such requests instead of sending a bogus
name.</li>
<li>Fix: a recurring timer that cancelled and immediately re-armed itself from within
its own callback leaked the old (cancelled) coroutine into the sleeping heap. The old
coroutine would sit there for its full delay (#213).</li>
<li>Fix: TLS <code>sslparams</code> tables that didn't contain the current
<code>wrap</code>/<code>sni</code> keys (e.g. an empty table, or one with misspelled keys)
were misidentified and silently ended up disabling TLS, producing a plaintext connection
with no error. Such tables are now passed through to LuaSec, which validates and errors on
them (#211).</li>
<li>Fix: a socket read/write/connect timeout left a stale entry in that socket's wait queue.
If the socket was reused afterwards (e.g. returned to a pool), a later real waiter could
queue up behind the stale entry and never get woken. Only a single waiter per direction is
now allowed; a conflicting second waiter gets an immediate "already in progress" error
instead of being silently abandoned (#209).</li>
<li>Fix: <code>timer:cancel()</code> could abandon an already in-flight callback instead of
letting it complete (#207).</li>
<li>Fix: several accounting bugs in <code>copas.semaphore</code>: <code>take()</code> and
<code>give()</code> didn't validate their amount, so negative, NaN, or infinite values could
corrupt or unbound the internal count; <code>destroy()</code> only released up to
<code>max</code> queued waiters instead of all of them; and <code>get_wait()</code> counted
waiters that had already been cancelled (#205).</li>
<li>Added <code>semaphore:release_all()</code> to
release every waiter past <code>max</code> (#205).</li>
<li>Fix: <code>copas.future</code> completion was capped at 9999 waiters; the cap has been
removed (#204).</li>
<li>Fix: <code>copas.lock:get()</code> with a zero timeout that failed to acquire immediately
still queued the caller, which then waited forever with nothing left to time it out (#202).</li>
<li>Fix: <code>copas.lock</code> and <code>copas.semaphore</code> could deadlock or leak
resources when a queued waiter was cancelled externally (e.g. via
<code>copas.removethread()</code> or <code>future:cancel()</code>) before being resumed --
<code>lock:release()</code> could hand ownership to a coroutine that would never run, and
<code>semaphore:give()</code> could deduct resources for a waiter that would never consume
them. <code>copas.wakeup()</code> now reports whether it actually woke a coroutine, so callers
can skip stale entries instead (#200).</li>
<li>Fix: <code>copas.http</code> silently fell back to plain HTTP when given a URL with an
unknown/unrecognized scheme, instead of erroring (#195).</li>
</ul></dd>
<dt><strong>Copas 4.11.0</strong> [11/Jun/2026]</dt>
<dd><ul>
<li>Feat: added <code>copas.cancelall()</code>. It cancels pending work to force-exit the loop.
Intended use is for testing, to force a loop exit, even if a test fails.</li>
<li>Fix: when a socket timeout occurs, the registers weren't properly cleaned. This caused
a memory leak. Fix by @haoxianhan in #186.</li>
</ul></dd>
<dt><strong>Copas 4.10.0</strong> [27/Mar/2026]</dt>
<dd><ul>
<li>Feat: added <code>copas.future</code> class. Wraps a thread in a future, allowing other
threads to wait for its result via <code>future:get()</code> or poll with <code>future:try()</code>.
Errors in the task are propagated to callers. Pending tasks can be cancelled with
<code>future:cancel()</code>.</li>
<li>Deps: bump LuaSocket to 3.x release.</li>
</ul></dd>
<dt><strong>Copas 4.9.0</strong> [11/Mar/2026]</dt>
<dd><ul>
<li>Feat: <code>copas.pause()</code> and <code>copas.pauseforever()</code> now return the
actual time slept, in case they got woken up early, and to return a truthy success value.</li>
<li>Fix: the <code>lock</code> and <code>semaphore</code> classes now use the proper coxpcall
version of <code>coroutine.running</code> in case of Lua 5.1, which could cause rare race-conditions.</li>
</ul></dd>
<dt><strong>Copas 4.8.0</strong> [13/Mar/2025]</dt>
<dd><ul>
<li>Change: Copas no longer requires LuaSocket, if no sockets are needed, LuaSystem will be enough as a fallback.</li>
<li>Feat: added <code>copas.gettime()</code>, which transparently maps to either LuaSockets or
LuaSystems implementation, ensuring independence of the availability of either one of those.</li>
<li>Feat: Controlled exit of the Copas loop. Adding <code>copas.exit()</code>, <code>copas.exiting()</code>, and
<code>copas.waitforexit()</code>.</li>
</ul></dd>
<dt><strong>Copas 4.7.1</strong> [9/Mar/2024]</dt>
<dd><ul>
<li>Fix: <code>copas.removethread</code> would not remove a sleeping thread immediately (it would not execute, but
would prevent the Copas loop from exiting until the timer expired).</li>
<li>Fix: <code>queue:finish</code> will return after the last item has been handled, not just popped
(if using workers).</li>
</ul></dd>

Because the Copas timeout resets on every chunk received (see the timeout note
above), a peer that trickles in bytes without ever sending a newline is not timed
out either, so the buffer keeps growing for as long as the peer stays connected.
Do not use the default <code>receive()</code>/<code>"*l"</code> pattern directly on
data from an untrusted or remote peer unless the protocol itself guarantees a
bounded line length. For untrusted input, read a bounded/known size (a numeric
pattern), or use <code>receivepartial</code> and enforce your own cumulative size

## NOTICE for Package Maintainers
- It is recommended to build FFmpeg twice, first with minimal external dependencies so that 3rd party packages, which depend on FFmpegs libavutil/libavfilter/libavcodec/libavformat
can then be built. And last build FFmpeg with full dependencies (which may in turn depend on some of these 3rd party packages). This avoids circular dependencies during build.
