  CVE-2017-9224, CVE-2017-9225, CVE-2017-9226
  CVE-2017-9227, CVE-2017-9228, CVE-2017-9229

---
Oniguruma is a modern and flexible regular expressions library. It
encompasses features from different regular expression implementations
that traditionally exist in different languages. It comes close to
being a complete superset of all regular expression features found
in other regular expression implementations.

Its features include:
* Character encoding can be specified per regular expression object.
* Several regular expression types are supported:
  * POSIX
  * Grep
  * GNU Regex
  * Perl
  * Java
  * Ruby
  * Emacs

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

Install

 Case 1: Linux distribution packages

   * Fedora:         dnf install oniguruma
   * RHEL/CentOS:    yum install oniguruma
   * Debian/Ubuntu:  apt install libonig5
   * Arch:           pacman -S oniguruma
   * openSUSE:       zypper install oniguruma

 Case 2: Manual compilation on Linux, Unix, and Cygwin platform

   1. autoreconf -vfi   (* case: configure script is not found.)

   2. ./configure
   3. make
   4. make install

   * uninstall

     make uninstall

   * configuration check

     onig-config --cflags
     onig-config --libs
     onig-config --prefix
     onig-config --exec-prefix



 Case 3: Windows 64/32bit platform (Visual Studio)

   execute make_win64 or make_win32

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

  * test (ASCII/Shift_JIS)
      1. cd src
      2. copy ..\windows\testc.c .
      3. nmake -f Makefile.windows ctest

  (I have checked by Visual Studio Community 2015)



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.
