SpellChecking - Method / Technology

Engine - Aspell

How:

• Icon on CM invokes spellchecker method.
• Method sends hex encoded content to spellcheck service (AJAX)
• Service decodes and scans content for misspellings, marks each of these with a special span of class named 'w3spelltarget', identified by unique id. 
• Service constructs list of suggested alternatives and places them in an xml container of with an attribute identifying the span id.
• Service re-encodes the content with added spans.
• Service construcs xml to send to the CM client, that has marked up content and lists of alternative spellings.
• Client replaces original content with span marked content from service.
• Client produces pop-up list of misspell candidates, along with combo choices from lists,  edit boxes for manual change and OK buttons
• On User click of OK, client will replace ID'ed span with either the chosen combo choice or manually entered text.
• Dismissal of the popup will remove any remaining span tags.

Thats It!

Version 0.1 code

I have created a wrapper class that makes interfacing with aspell much easier.
I have an example program source file to use as an example, and as a starting point for more sophisticated code.
Here is the makefile.
You aslo need the aspell development environment which you can get here.
