Spellcheck Extension for Arbitrary Web Pages
Write an extension to leverage the existing spellcheck code in Mozilla and add the ability to highlight spelling mistakes for a given web page (i.e., vs. a textbox).
Make an extension that have the menus for spell checking but not yet do anything.
09/23/2008 - Talked through email with Neil Deakin about the parts of code I will need probably need to modify 10/13/2008 - Got my first extension up an running
IRC log of conversation about this extension
- 12:14 <@dave> how hard would it be to add Tools > Spell-Check?
- 12:14 <@dave> i.e., for an arbitrary page vs. textbox
- 12:14 < shaver> good question
- 12:15 <@dave> or probably what I mean is Tools > Highlight Spelling Mistakes
- 12:19 < shaver> you'd want a presentation like the findbar?
- 12:19 <@dave> depends on use case, but that's one good one, yeah
- 12:19 <@dave> I'm thinking of being able to just underline all mispelled words on the page
- 12:23 < mfinkle> look into http://mxr.mozilla.org/seamonkey/source/editor/txtsvc/public/nsIInlineSpellChecker.idl
- 12:23 < mfinkle> it is keyed to use an editor
- 12:23 < mfinkle> but the code inside could be useful
- 12:23 <@dave> I should talk to enn I guess
- 12:24 < mfinkle> the red squiggle is done using a special kind of selection type
- 12:25 <@dave> mfinkle: yeah, I've seen that code before.
- 12:25 <@dave> the selection
- 12:25 < mfinkle> http://mxr.mozilla.org/seamonkey/source/extensions/spellcheck/src/mozInlineSpellChecker.cpp
- 12:25 <@dave> but this idl looks interesting
- 12:25 < mfinkle> is an inline spellcheck implementation for editors
- 12:26 < mfinkle> DoSpellCheck does some heavy lifting
- 12:27 < mfinkle> whoops, down a few lines
- 12:28 <@dave> 1278 if (! editor)
- 12:28 <@dave> 1279 return NS_ERROR_FAILURE;
- 12:28 <@dave> hm
- 12:28 < mfinkle> yeah, but it seems to use ranges, so swapping in a document shouldn't be impossible
- 12:29 < mfinkle> and notice that mSpellCheck is an instance of the real spellcheck engine
- 12:29 <@dave> yeah
- 12:29 <@dave> I'm trying to find uses of editor, and it's thin
- 12:31 < mfinkle> well mSpellCheck is a nsIEditorSpellCheck
- 12:31 < mfinkle> must go deeper
- 12:33 < mfinkle> crap, nsISpellCheck is not public - wtf
- 12:33 <@dave> weird
- 12:33 < shaver> fixable, I bet
- 12:34 < mfinkle> I suppose building directly against the tree (instead of the sdk) is doable
- 12:34 <@dave> so this is a tree exercise vs. an ext
- 12:34 < mfinkle> kinda like vlad's canvas3d
- 12:34 < mfinkle> right
- 12:34 < shaver> no, it's an extension
- 12:34 < mfinkle> well, it can be an extension
- 12:34 < shaver> it's just not one that can use only frozen APIs
- 12:34 < mfinkle> but it needs the tree
- 12:34 < shaver> like basically any useful extension
- 12:34 <@dave> :)
- 12:34 < mfinkle> sadly
- 12:35 < mfinkle> but anyway - onward
- 12:35 <@dave> I think I'll take some notes here and craft a project for future
- 12:35 < mfinkle> http://mxr.mozilla.org/seamonkey/source/extensions/spellcheck/src/mozSpellChecker.cpp
- 12:35 < mfinkle> implements the nsISpellCheck interface
- 12:36 < mfinkle> takes an nsITextServicesDocument
- 12:36 <@dave> how generic is that?
- 12:38 < mfinkle> can be initialized with a document! http://mxr.mozilla.org/seamonkey/source/editor/txtsvc/src/nsTextServicesDocument.cpp#175
- 12:38 < mfinkle> promising
- nsISpellCheck interface
