Show all versions of jazzy Show documentation

A set of APIs that allow you to add spell checking functionality to Java Applications easily. Jazzy is based on most of the algorithms that aspell has; so the suggestions they come up with are very similar. Note that this is not an official release from the jazzy project; it is a release of 0.5.2 with enhancements / bug-fixes as required by the RText SpellChecker project hosted on www.fifesoft.com. The scm urls in this pom indicate where the enhanced source code is hosted

There is a newer version: 0.5.2-rtext-1.4.1-2
