What I have done so far

  • Downloaded the original version of THunSpell by Stefan Ascher from (https://torry.net/authorsmore.php?id=7163), the original version is assumed to be developed for Delphi 6 (Non-unicode Delphi).
  • Upgraded to unicode Delphi (tested on XE4 only) and the demo is running correctly.
  • Re-orgnaized the repository directory (moved all demo-related files to the Demo subfolder).
  • Still uses Hunspell DLL version 1.3.2 from year 2011.

Other spell check libraries/components

My experiences only:

  • LS Speller (TSpellChecker): This is the one I used in pre-Unicode Delphi, but it doesn't support Delphi 2009+ and I failed to upgrade it to support Unicode Delphi.
  • TMS Spell Checker: I only have the 2017 version and didn't find its spell check dialog directly supporting TRichEdit, and man, it's not very fast...
  • NHunspell: Another Hunspell wrapper which uses much newer Hunspell DLL, but it doens't have built-in spell check dialog which can directly operate on a TCustomMemo descendent, and that's why I end up upgrading THunSpell.

Advantages of THunSpell over the above mentioned alternatives

  • It's fast!
  • Has a THunSpellDialog which can direclty check and correct words in a TMemo.
  • Has a TMemo-derived class which draws red lines under words that failed to be validated by Hunspell.

Possible future enhancements

  • Upgrade to the latest Hunspell (try refer to NHunspell mentioned above, I won't do this in the near future unless needed).
  • Ensure THunSpellDialog supports TRichEdit/TJvRichEdit (I'll be doing this soon, but will test against TJvRichEdit only).
  • If you make pull request, try your best not to break backward compatibilities (XE4, for example).
