== 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 http://mxr.mozilla.org/seamonkey/source/extensions/spellcheck/src/mozInlineSpellChecker.cpp#1223
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
