Spelling engine status [message #505641]

Hi,
I did a bit of research, but I'm still confused.
It seems to me there *is* some support for Spell-checking in a generic
TextEditor (or an AbstractDecoratedTextEditor), but it is still packaged
into JDT, which means I will have to pull into my RCP app a lot of
unwanted code.

First and foremost:
Is this correct? Will this change soon (E4)?

Then:
Where can I find reasonably complete instructions on how to add the
current spell-checking to my app?
How do I produce additional "Platform dictionaries"? I know I can add
"custom dictionaries" (one word per line), but I would like to have a
standard (platform?) dictionary *and* let the user add a special-purpose
custom dict.

There is a set of slides floating around (Text Editor Recipes) that seem
to indicate this is not too complex, but slides alone are not very
informative :(

Can someone enlighten me, please?

Best Regards
Mauro

Yes, the general framework is in lower layers but JDT contributes the
engine for historical reasons.

Not soon i.e. definitely not with this year's 3.x / e4 releases.

There's currently no easy way. You have to create your own spelling
engine which can either be a copy of the JDT one or your won.

Create a file <locale>.dictionary (e.g. de_CH.dictionary) with a word on
each line. Then ship it as fragment of org.eclipse.jdt.ui/dictionaries.

Look how the JDT spelling engine does it.

Well, I have tried what you have written and it really works - i. e. it is sufficient to put once custom dictionary into the "eclipse/plugins/org.eclipse.jdt.ui_VERSION.jar" - into the "dictionaries" folder and start Eclipse again.

BUT what can spare you some precious time is to know that the name of the dictionary file must be EXACTLY <language>_<country>.dictionary. The shortened form - <language>.dictionary - seems to be UNSUPPORTED: Although the dictionary does appear in the "Platform dictionary" combobox (in the Preferences dialog) and you can select it, the selection is in fact ignored and reverted to "none". Maybe a bug to report?

Best regards

Petr

Yes, please file one against JDT Text.

Well, while searching for possible duplicates, I have found out that this problem was in fact already reported some year ago:

[spell checking] Locales without country code don't work

So I'm not sure about opening a new bug now. Maybe you could reopen the existing one, changing its severity to ENHANCEMENT?
