Hello!
I'm maintaining system-wide Latvian spell checker for ~ 2 years. It
works as intended on 10.4 and 10.5.
Just made a dummy spellcheck for 10.6. checking out the new SDK. Works
great...
...except for the (only) new "Automatic by Language" option introduced
in 10.6.
Problem description (pardon if failed to keep it shorter) :
After installing (see Compiled service structure) the spell check,
opening i.e. TextEdit, I am able to check spelling for the registered
(here- Latvian) language by setting "Latvian" in "Spelling and Grammar".
The words that are not in the language (in wordsAray) are underlined,
right-clicking them gives me a list of possible corrections
(suggestion1, suggestion2,...), pressing esc gives the possible
completions. I mean - everything works.
As I switch to "Automatic by language" in "Spelling and Grammar" a
weird behaviour occurs - it doesn't work as intended.
Text written in English, German a.o. Apple supported languages is
correctly checked.
Text written in Latvian is ... underlined as incorrect. However, when
right-clicking these underlined words or invoking completion I get the
suggestions that are delivered by my FooSpellCheck, that is,
NSSpellServer is calling methods
- (NSArray *)spellServer:(NSSpellServer *)sender
suggestCompletionsForPartialWordRange:(NSRange)range inString:
(NSString *)string language:(NSString *)language;
- (NSArray *)spellServer:(NSSpellServer *)sender suggestGuessesForWord:
(NSString *)word inLanguage:(NSString *)language;
to my spellcheck!, however methods
// New method: Search for a misspelled word in a given string
- (NSArray *)spellServer:(NSSpellServer *)sender checkString:(NSString
*)stringToCheck offset:(NSUInteger)offset types:(NSTextCheckingTypes)
checkingTypes options:(NSDictionary *)options orthography:
(NSOrthography *)orthography wordCount:(NSInteger *)wordCount;
// Old method: Search for a misspelled word in a given string
- (NSRange)spellServer:(NSSpellServer *)sender
findMisspelledWordInString:(NSString *)stringToCheck language:
(NSString *)language wordCount:(NSInteger *)wordCount countOnly:(BOOL)
countOnly;
aren't! THEY SHOULD! Simply NSLog'ing the runtime shows this clearly.
Note: Yes, in sysprefs language&text everything is set/checked as
needed under Automatic by Language setup.
• So is this this a bug in Foundation frameworks NSSpellServer?
• Or is it just me?
• Or automatic by language is reserved for apple provided languages
only? (If so, they have bug in system preferences, as FooSpellCheck
provided Latvian language shows up there and user is able to select it
as one of langages for "automatic").
• If only New method is implemented then rightclicking misspelled
word, when spelling options set to "Latvian only", doesn't call -
spellServer:suggestGuessesForWord:inLanguage:language, it is called
ONLY when checking spelling through Spelling and Grammar panel (cmd
+ : ) For OSX built-in languages right-clicking invokes list of
possible corrections. However, when "automatic" is selected, then list
is called. D'oh?
As I am going blind in this problem, tried things like changing
registered language id (lv, lv_LV, Latvian, Latviešu). I have tried to
run FooSpellCheck in 3 ways:
Implementing both or only the new or only the old method for misspeled
word search
// New method: Search for a misspelled word in a given string
// Old method: Search for a misspelled word in a given string
Have changed the vendor id and NSSpellChecker in Info.plist, a.o.
"shots in the dark".
Before putting out spellcheck for 10.6. I'd really liked to solve this
issue, or if this cannot be solved :) then I can clearly comment this
problem in my spellchecks documentation.
Any suggestions/directions?
Many thanks in advance,
Reinis Adovics
