About Hunspell
|
|
==============
|
|
|
|
NOTICE: Version 2 is in the works. For contributing see
|
|
[version 2 specification][v2spec] and the folder `src/hunspell2`.
|
|
|
|
[v2spec]: https://github.com/hunspell/hunspell/wiki/Version-2-Specification
|
|
|
|
Hunspell is a spell checker and morphological analyzer library and program
|
|
designed for languages with rich morphology and complex word compounding or
|
|
character encoding. Hunspell interfaces: Ispell-like terminal interface
|
|
using Curses library, Ispell pipe interface, C++ class and C functions.
|
|
|
|
Hunspell's code base comes from the OpenOffice.org MySpell
|
|
(http://lingucomponent.openoffice.org/MySpell-3.zip). See README.MYSPELL,
|
|
AUTHORS.MYSPELL and license.myspell files.
|
|
Hunspell is designed to eventually replace Myspell in OpenOffice.org.
|
|
|
|
Main features of Hunspell spell checker and morphological analyzer:
|
|
|
|
- Unicode support (affix rules work only with the first 65535 Unicode
|
|
characters)
|
|
- Morphological analysis (in custom item and arrangement style) and stemming
|
|
- Max. 65535 affix classes and twofold affix stripping (for agglutinative
|
|
languages, like Azeri, Basque, Estonian, Finnish, Hungarian, Turkish, etc.)
|
|
- Support complex compoundings (for example, Hungarian and German)
|
|
- Support language specific features (for example, special casing of
|
|
Azeri and Turkish dotted i, or German sharp s)
|
|
- Handle conditional affixes, circumfixes, fogemorphemes,
|
|
forbidden words, pseudoroots and homonyms.
|
|
- Free software. Versions 1.x are licenced under LGPL, GPL, MPL tri-license.
|
|
Version 2 is licenced only under GNU LGPL.
|
|
|
|
Compiling on GNU/Linux and Unixes
|
|
=================================
|
|
|
|
autoreconf -vfi
|
|
./configure
|
|
make
|
|
sudo make install
|
|
sudo ldconfig
|
|
|
|
For dictionary development, use the `--with-warnings` option of configure.
|
|
|
|
For interactive user interface of Hunspell executable, use the `--with-ui option`.
|
|
|
|
The developer packages you need to compile Hunspell's interface:
|
|
|
|
autoconf automake autopoint libtool g++
|
|
|
|
Optional developer packages:
|
|
|
|
- ncurses (need for --with-ui), eg. libncursesw5 for UTF-8
|
|
- readline (for fancy input line editing,
|
|
configure parameter: --with-readline)
|
|
- locale and gettext (but you can also use the
|
|
--with-included-gettext configure parameter)
|
|
|
|
Compiling on Windows
|
|
====================
|
|
|
|
## 1. Compiling with Mingw64 and MSYS2
|
|
|
|
Download Msys2, update everything and install the following packages:
|
|
|
|
pacman -S base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-libtool
|
|
|
|
Open Mingw-w64 Win64 prompt and compile the same way as on Linux, see above.
|
|
|
|
## 2. Compiling in Cygwin environment
|
|
|
|
Download and install Cygwin environment for Windows with the following
|
|
extra packages:
|
|
|
|
- make
|
|
- automake
|
|
- autoconf
|
|
- libtool
|
|
- gcc-g++ development package
|
|
- ncurses, readline (for user interface)
|
|
- iconv (character conversion)
|
|
|
|
Then compile the same way as on Linux. Cygwin builds depend on Cygwin1.dll.
|
|
|
|
Debugging
|
|
=========
|
|
|
|
For debugging we need to create a debug build and then we need to start `gdb`.
|
|
|
|
make clean
|
|
make CXXFLAGS='-g -O0'
|
|
libtool --mode=execute gdb src/tools/hunspell
|
|
|
|
Testing
|
|
=======
|
|
|
|
Testing Hunspell (see tests in tests/ subdirectory):
|
|
|
|
make check
|
|
|
|
or with Valgrind debugger:
|
|
|
|
make check
|
|
VALGRIND=[Valgrind_tool] make check
|
|
|
|
For example:
|
|
|
|
make check
|
|
VALGRIND=memcheck make check
|
|
|
|
Documentation
|
|
=============
|
|
|
|
features and dictionary format:
|
|
|
|
man 5 hunspell
|
|
man hunspell
|
|
hunspell -h
|
|
|
|
http://hunspell.github.io/
|
|
|
|
Usage
|
|
=====
|
|
|
|
The src/tools directory contains ten executables after compiling:
|
|
|
|
- affixcompress: dictionary generation from large (millions of words)
|
|
vocabularies
|
|
- analyze: example of spell checking, stemming and morphological analysis
|
|
- chmorph: example of automatic morphological generation and conversion
|
|
- example: example of spell checking and suggestion
|
|
- hunspell: main program for spell checking and others (see manual)
|
|
- hunzip: decompressor of hzip format
|
|
- hzip: compressor of hzip format
|
|
- makealias: alias compression (Hunspell only, not back compatible with MySpell)
|
|
- munch: dictionary generation from vocabularies (it needs an affix file, too).
|
|
- unmunch: list all recognized words of a MySpell dictionary
|
|
- wordforms: word generation (Hunspell version of unmunch)
|
|
|
|
After compiling and installing (see INSTALL) you can
|
|
run the Hunspell spell checker (compiled with user interface)
|
|
with a Hunspell or Myspell dictionary:
|
|
|
|
hunspell -d en_US text.txt
|
|
|
|
or without interface:
|
|
|
|
hunspell
|
|
hunspell -d en_UK -l <text.txt
|
|
|
|
Dictionaries consist of an affix and dictionary file, see tests/
|
|
or http://wiki.services.openoffice.org/wiki/Dictionaries.
|
|
|
|
Using Hunspell library with GCC
|
|
===============================
|
|
|
|
Including in your program:
|
|
|
