Oniguruma is a regular expressions library.
The characteristics of this library is that different character encoding
for every regular expression object can be specified.

Supported character encodings:

  ASCII, UTF-8,
  EUC-JP, EUC-TW, EUC-KR, EUC-CN,
  Shift_JIS, Big5, KOI8, KOI8-R,
  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

(Please use Oniguruma 5.X.X if you want to use UTF-16/UTF-32.)


There are two ways of using of it in this program.

  * Built-in regular expression engine of Ruby 1.6/1.8
  * C library (supported APIs: GNU regex, POSIX, Oniguruma native)

In Ruby 1.9, Oniguruma 4.X is already integrated by Kazuo Saito.

Install

(A) Install into Ruby

   See INSTALL-RUBY.

   (character encodings:  ASCII, UTF-8, EUC-JP, Shift_JIS)


(B) Install C library

 (B-1) Unix and Cygwin platform

   1. ./configure
   2. make
   3. make install

   (* uninstall:  make uninstall)

  * test (ASCII/EUC-JP)
   4. make ctest


 (B-2) Win32 platform (VC++)

   1. copy win32\Makefile Makefile
   2. copy win32\config.h config.h
   3. nmake

      onig_s.lib:  static link library
      onig.dll:    dynamic link library

  * test (ASCII/Shift_JIS)
   4. copy win32\testc.c testc.c
   5. nmake ctest

Usage

  Include oniguruma.h in your program. (Oniguruma API)
  See doc/API for Oniguruma API.

  If you want to use static link library(onig_s.lib) in Win32,
  add option -DONIG_EXTERN=extern to C compiler.

API differences with Japanized GNU regex(version 0.12) of Ruby

   + re_compile_fastmap() is removed.
   + re_recompile_pattern() is added.
   + re_alloc_pattern() is added.


I'm thankful to Akinori MUSHA.
