Onigmo (Oniguruma-mod) -- (C) K.Takata
https://github.com/k-takata/Onigmo
Onigmo is a regular expressions library forked from Oniguruma.
It focuses to support new expressions like `\K`, `\R`, `(?(cond)yes|no)`
and etc. which are supported in Perl 5.10+.
Since Onigmo is used as the default regexp library of Ruby 2.0 or later,
many patches are backported from Ruby 2.x.
See also the Wiki page:
https://github.com/k-takata/Onigmo/wiki
Main New features:
Regular Expressions (depends on the syntax):
\K, \R, \X, (?(cond)yes|no)
(?adlu), \g{name}, \g{n}, (?&name), (?n), (?R), (?0)
(?P...), (?P=name), (?P>name)
API:
onig_search_gpos (for Perl-compatible \G)
Encoding:
CP932, CP1250, CP1251, CP1252, CP1253, CP1254, CP1257
Syntax:
Python

EUC-JP, EUC-TW, EUC-KR, EUC-CN,
Shift_JIS, Big5, GB18030, KOI8-R, CP1251,
ISO-8859-1, ISO-8859-2, ISO-8859-3, ISO-8859-4, ISO-8859-5,

Regular Expressions
See doc/RE (or doc/RE.ja for Japanese).
Usage
Include oniguruma.h in your program. (Oniguruma API)
See doc/API for Oniguruma API.
If you want to disable UChar type (== unsigned char) definition
in oniguruma.h, define ONIG_ESCAPE_UCHAR_COLLISION and then
include oniguruma.h.
If you want to disable regex_t type definition in oniguruma.h,
define ONIG_ESCAPE_REGEX_T_COLLISION and then include oniguruma.h.
Example of the compiling/linking command line in Unix or Cygwin,
(prefix == /usr/local case)
cc sample.c -L/usr/local/lib -lonig
If you want to use static link library(onig_s.lib) in Win32,
add option -DONIG_EXTERN=extern to C compiler.
Sample Programs
sample/simple.c example of the minimum (Oniguruma API)
sample/names.c example of the named group callback.
sample/encode.c example of some encodings.
sample/listcap.c example of the capture history.
sample/posix.c POSIX API sample.
sample/sql.c example of the variable meta characters.
(SQL-like pattern matching)
Test Programs
sample/syntax.c Perl, Java and ASIS syntax test.
sample/crnl.c --enable-crnl-as-line-terminator test

ToDo
? case fold flag: Katakana <-> Hiragana.
? add ONIG_OPTION_NOTBOS/NOTEOS. (\A, \z, \Z)
?? \X (== \PM\pM*)
?? implement syntax behavior ONIG_SYN_CONTEXT_INDEP_ANCHORS.
?? transmission stopper. (return ONIG_STOP from match_at())
and I'm thankful to Akinori MUSHA.
