broken since bd291d21f096a714a171e7af3a534ba345ca5659 (about two years ago) because it called \
Sonnet::Speller::setLanguage every time the spellchecker was invoked, which was not thread-safe. This \
diff fixes the segfaults, and the feature, which I understand to be, basically, the ability to type \
'spell french bonjour' and have it check the spelling.
The current code simply calls setLanguage on the second term in the search query, and then checks whether \
the resulting dictionary object is valid. The spell-checker expects languages like 'fr_FR' or \
'French (France)' which the user was unlikely to type in correctly (at least, I never figured it \
out until I read the source).
Instead, this patch create a new spell-check object (the creation is guarded by a mutex) when a new \
language is used (thus never needing to call setLanguage). Future queries use the already created speller \
for the new language, and spellers are deleted on the teardown() signal.
We make a map between the speller codes and simple natural language language names in init(); this is a \
little bit tricky, because languages have sub-variants. My approach was to try and find the main language \
of the group: so 'french' gets you fr_FR. For english I defaulted to US english.
I have not tested this spelling an asian language as I don't speak one.
I have not implemented 'spell canadian french' or similar. If you want a specific sublanguage you \
have to type in the language code directly.</pre> </td>
