Today I found a great AJAX based spellchecker demo which uses ActionPack instead of ActiveRecord. As with many Rails applications this wonderful app only requires 67 lines of code plus a few HTML templates. “PrimaGrasp has put up an excellent demo of their AJAX and ruby on rails based spellchecker. Unfortunately they have not put up the source code at this point, but I have emailed them to ask : ) “rnSpell checking is done via GNU Aspell, which is a Free and Open Source spell checker designed to eventually replace Ispell. It can either be used as a library or as an independent spell checker. Its main feature is that it does a superior job of suggesting possible replacements for a misspelled word than just about any other spell checker out there for the English language.”rnSpelling suggestions are offered via AJAX powered links which is the same system used in GMail, I found the spellchecker to be a very intuitive application, and can see many uses for it. Spellchecking comments will be my first experiment if PrimaGrasp releases the source code. “”Hats off to the devlopers!”rnThe demo has only been tested on Firefox so if you can’t view the demo upgrade to a better browser. rn
