About Hunspell
--------------

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, OpenOffice.org UNO module.

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)

- 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 (LGPL, GPL, MPL tri-license)

Compiling
---------

./configure
make
make install

For dictionary development, use the --with-warnings option of configure.

For compiling morphological analyser and stemmer code and tools, use the
--with-experimental 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:

glibc-devel

optional developer packages:

ncurses (need for --with-ui)
readline (for fancy input line editing,
  configure parameter: --with-readline)
locale and gettext (but you can also use the
  --with-included-gettext configure parameter)

Hunspell distribution uses new Autoconf (2.59) and Automake (1.9).

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 4 hunspell

man hunspell
hunspell -h

Usage
-----

The src/tools dictionary contains three executables.
A spell checker with Ispell-like curses interface and Ispell
compatible pipe interface (hunspell) and two small example
program (hunmorph and hunstem).

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_UK text.txt

or without interface:

hunspell -d en_UK -l <text.txt

(Dictionaries consists of an affix and dictionary file.)

Usage of Hunmorph morphological analyzer:

hunmorph en_UK.aff en_UK.dic input_file

Using Hunspell library with GCC
-------------------------------

Including in your program:
#include <hunspell.hxx>

Linking with Hunspell static library:
