TSynSpellCheck Help

You may notice that some versions are published after just one or two changes are made. This is because as soon as a bug is fixed I try to publish the new version A.S.A.P. When adding new features I like to add some changes and them publish them.

Version history:

1.30 (Contributed in large by Jan Fiala)

1. Many, many minor adjustments, optimizations.
2. Rewritten SetApostrophes().
3. New word suggestion algorithm: haDiff. Finds words based on differences. haSoundex and haMetaphone *may* be removed in upcoming versions.
4. New action added: ACTION_UNDO.
5. New function: GetDictionaryDir(). This allows users to specify their own paths.
6. Dutch (compiled by Arno Verhoeven) dictionary added.

1.24 Released privately to certain users.

1. Bug Fix: PChar and string incompatiblity. Fixed.

1.23 Released privately to certain users.

1. Minor code adjustments.
2. New dictionaries: Norwegian and Spanish.

1.22

1. Bug Fix: The Apostrophes property did not allow changing. Fixed. Submitted by R.K. Wittye.
2. Bug Fix: ClearDictWords did not properly dispose of words creating a rather large memory leak. Fixed. Submitted by Ascher Stefan.
3. English and Polish dictionaries updated.
4. Added Value field to TWordRec record. Each word is assigned an Elf value and is checked by it. Major speed optimization. Suggested by Jan Fiala (CRC32).

1.21

1. Bug Fix: %ProgramFilesDir%\Common Files was read instead of %CommonFilesDir%. This created problems on non-English versions of Windows. The directory was not found. Fixed.
2. English and Polish dictionaries updated.

1.20

1. FindWord() routine rewritten to make use of cache array. Other functions have only been slightly modified yet no functions have been broken.
2. LoadDictionary() routine now converts all words to lowercase.
3. LoadSkipList() does not add the words one-by-one any more. They are assigned in whole.
4. FSkipList is now cleared when a dictionary is closed.
5. SaveSkipList() now removes all empty lines before saving to file.
6. Added cache array to speed up word checks.
7. ENoDictionaryLoaded is now thrown when no dictionary has been loaded.

1.19

1. Bug Fix: Word underlining would also draw on gutter when the word was partially scrolled under it. Fixed.
2. SoundexLength property converted to HashLength.
3. PaintUnderLine() code modified to directly color pixels instead of drawing lines.
4. Dictionary updates: English (1.1.2), Polish (1.1.1). The Polish word list has been *significantly* reduced due to the fact that this word list is being started all over to include words with non-latin characters.
5. New option: sscoTrimApostrophes.
6. New properties: Busy and UnderlineStyle (to mimic Corel Wordperfect auto spell checking).
7. MetaPhone algorithm has been finally implemented. In beta stage (works, but slow on big lists).
