Oniguruma
=========
https://github.com/kkos/oniguruma
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

Install
-------
### Case 1: 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 2: Windows 64/32bit platform (Visual Studio)
Execute make_win.bat
onig_s.lib: static link library
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)
Alternatively, you can build and install oniguruma using [vcpkg](https://github.com/microsoft/vcpkg/) dependency manager:
1. git clone https://github.com/Microsoft/vcpkg.git
2. cd vcpkg
3. ./bootstrap-vcpkg.bat
4. ./vcpkg integrate install
5. ./vcpkg install oniguruma
The oniguruma port in vcpkg is kept up to date by microsoft team members and community contributors.
If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
Regular Expressions
-------------------
See [doc/RE](doc/RE) or [doc/RE.ja](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.
