Oniguruma is a modern and flexible regular expressions library. It encompasses features from different regular expression implementations that traditionally exist in different languages.

Character encoding can be specified per regular expression object.

Supported character encodings:

ASCII, UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE, 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, ISO-8859-6, ISO-8859-7, ISO-8859-8, ISO-8859-9, ISO-8859-10, ISO-8859-11, ISO-8859-13, ISO-8859-14, ISO-8859-15, ISO-8859-16

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.
