THunSpell
Delphi hunspell wrapper with a spell check dialog and a red-underline TMemo descendent, originally written by Stefan Ascher

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).
