MySpell is a simple spell checker that uses affix
compression and is modelled after the spell checker
MySpell was written to explore how affix compression
can be implemented.
The Main features of MySpell are:
1. written in C++ to make it easier to interface with
Pspell, OpenOffice, AbiWord, etc
2. it is stateless, uses no static variables and
should be completely reentrant with almost no
3. it tries to be as compatible with ispell to
the extent it can. It can read slightly modified
versions of munched ispell dictionaries (and it
comes with a munched english wordlist borrowed from
Kevin Atkinson's excellent Aspell.
4. it uses a heavily modified aff file format that
can be derived from ispell aff files but uses
the iso-8859-X character sets only
5. it is simple with *lots* of comments that
describes how the affixes are stored
and tested for (based on the approach used by
6. it supports improved suggestions with replacement
tables and ngram-scoring based mechanisms in addition
to the main suggestion mechanisms
7. like ispell it has a BSD license (and no
But ... it has *no* support for adding words
to a personal dictionary, *no* support for converting
between various text encodings, and *no* command line
interface (it is purely meant to be a library).
It can not (in any way) replace all of the functionality
of ispell or aspell/pspell. It is meant as a learning
tool for understanding affix compression and for
being used by front ends like OpenOffice, Abiword, etc.
MySpell has been tested under Linux and Solaris
and has the world's simplest Makefile and no
It does come with a simple example program that
spell checks some words and returns suggestions.
To build a static library and an example
program under Linux simply type:
tar -zxvf myspell.tar.gz
To run the example program:
./example ./en_US.aff ./en_US.dic checkme.lst
