LIBUNIBREAK

Overview

This is the README file for libunibreak, an implementation of the line breaking and word breaking algorithms as described in Unicode Standard Annex 14 and Unicode Standard Annex 29. Check the project's home page for up-to-date information.

Licence

This library is released under an open-source licence, the zlib/libpng licence. Please check the file LICENCE for details.

Apart from using the algorithm, part of the code is derived from the Unicode Public Data, and the Unicode Terms of Use may apply.

Installation

There are three ways to build the library:

1. On *NIX systems supported by the autoconfiscation tools, do the normal

    ./configure
    make
    sudo make install
   

   to build and install both the dynamic and static libraries. In addition, one may

   • type make doc to generate the doxygen documentation; or
   • type make linebreakdata to regenerate linebreakdata.c from LineBreak.txt.
   • type make wordbreakdata to regenerate wordbreakdata.c from WordBreakProperty.txt.
   • type make graphemebreakdata to regenerate graphemebreakdata.c from GraphemeBreakProperty.txt.
   • type make emojidata to regenerate emojidata.c from emoji-data.txt.

2. On systems where GCC and Binutils are supported, one can type

    cd src
    cp -p Makefile.gcc Makefile
    make
   

   to build the static library. In addition, one may

   • type make debug or make release to explicitly generate the debug or release build;
   • type make doc to generate the doxygen documentation; or
   • type make linebreakdata to regenerate linebreakdata.c from LineBreak.txt.
   • type make wordbreakdata to regenerate wordbreakdata.c from WordBreakProperty.txt.
   • type make graphemebreakdata to regenerate graphemebreakdata.c from GraphemeBreakProperty.txt.
   • type make emojidata to regenerate emojidata.c from emoji-data.txt.

3. On Windows, apart from using method 1 (Cygwin/MSYS) and method 2 (MinGW), MSVC can also be used. Type

    cd src
    nmake -f Makefile.msvc
   

   to build the static library. By default the debug version is built. To build the release version

    nmake -f Makefile.msvc CFG="libunibreak - Win32 Release"
   

Documentation

Check the generated document doc/html/linebreak_8h.html, doc/html/wordbreak_8h.html, and doc/html/graphemebreak_8h.html in the downloaded file for the public interfaces exposed to applications.

Examples

See the tools directory for basic examples (as test code). A more real utility is breaktext.
