278312 - Inline Spell Checker Back End

Status: RESOLVED FIXED

(Thunderbird :: Message Compose Window, defect)

Description

[Scott MacGregor]

The changes to layout to support inline spell checking. Broken out from Bug #58612

Comment 1

[Scott MacGregor]

Attachment: current draft of editor changes (still a work in progress)

Some of this came from Neil's original patch in 58612.

Comment 2

[Scott MacGregor]

Attachment: extensions\spellcheck patch

Comment 3

[Scott MacGregor]

Attachment: layout changes

This part is pretty much unchanged from Neil's original patch with the
exception of changes I made to nsTextFrame.cpp

I also re-merged his layout changes back to the trunk where files have been
moved and changed since mozilla 1.6.

Comment 4

[Scott MacGregor]

Attachment: more layout changes

adjust the underline color for misspelled words to be a red dotted line

Comment 5

[Scott MacGregor]

Attachment: more spell checker changes

1) re-write the inline spell checker to work on end of word delimiters instead
of on every character you type. 
2) When you backspace back to a mispelled word, clear out the underline. Add
the underline back in after a word delimter is added.
3) line breaks should cause us to spell check the last word before the br
element is added even if there isn't a word delimter.
4) add argument bullet proofing
5) use error macros and avoid some early returns

Comment 6

[Scott MacGregor]

Attachment: editor update

revamp the APIs and JS interface for accessing the inline spell checker.
Simplify some of the editor changes.

Comment 7

[Scott MacGregor]

Note to self:

1) Use the I18N word breaker routine to figure out when we've reached the end of
the word instead of calling IsEndOfWordChar.

2) apostrophes don't work correctly (doonnnn't) because
nsTextServicesDocument::FindWordBounds treats ' as a end of word terminator

Comment 8

more layout changes

David, are you the right person to review thes changes to nsFrame and
nsSelection or should I find someone else? Most of these changes were actually
made my Neil Deakin for some work he did for NVU, I'm just picking up that part
of his patch and using it for inline spell checking.

Comment 9

[Scott MacGregor]

Comment on attachment 171312 [details] [diff] [review]
editor update

Hi Daniel, these are the core editor changes required to support inline spell
checking. Most of this should look familiar as it is based on Neil's patch for
for NVU.

editor update

Nothing major but one clarification (quotation marks) and a double-check
(leaks) needed.

You're sure about that ? A class name _is_ case sensitive. I understand you
consider that
"moz-signature" value can only come from inside Mozilla but is it really worth
the time
spent to ignore case ?

Worried me a bit because the inlinespellchecker keeps a ref to the editor
that itself keeps a ref to the inlinespellchecker, but the former being a weak
reference, there should be no leak. Please double-check.

Scott, I still don't understand the quotes test. Why only single-quotes ?

updated editor patch, removes unnecessary code in nsTextServicesDocument.

Thanks for making me revist the change in
nsTextServicesDocument::FindWordBounds
with the check for single quotes. 

That part of the patch was from Neil's original code. I think he was trying to
work around a problem with the I18n word breaker later on in the spell check
code when it trys to handle apostrophes. Where it does handle " correctly.

I was able to safely remove this code altogether as I'm working on changes
further down the pipeline to make the word breaker handle apostrophes.

Why are you yelling?  And what does this mean, anyway?

Comment 19

[Scott MacGregor]

Attachment: updated spellcheck module changes (supports navigation)

This latest update to the spell check directory adds support for using the
arrow keys to navigate to another word (we now spell check the old word). For
using the mouse to move to another word (we now spell check the old word). And
initial support for pasting a group of words into the compose window. We now
spell check the new pasted text. 

This patch makes the inline spell checker instance register as a mouse and key
dom even listener so we can track all of these events.

Comment 20

[Scott MacGregor]

Attachment: latest round of changes

Fixes include:
1) proper support for copy and paste
2) several code optimizations 
3) mispell two words in a row in a bullet item then hit return, before we would
undo t spelling underline on the first word
4) we now properly recognize URLS of the form http://foo or mailto:foo. When
pasting we never underling these words at all. When typing, we'll underline the
scheme name due to a hard to fix bug. 
5) mispellings for words with apostrophes like didnn't now get underlined
instead of treating the apostrophe as a word separator. In general we are much
smarter about guessing what a word is.
6) Add word to the dictionary issues should be fixed (with words that had
multiple spaces between them.

This looks like a merging error and should probably be undone.

sr=dbaron given comment 21.  And actually ignore comment 18 if you want -- I
see that that comment was there before.

But please make sure that you check in the whitespace changes that the "diff
-w" ignores.

updated patch with David Baron's review comments. Moving forward his review.

Attachment: updated editor patch

Just re-freshing the editor changes against the trunk again. There was a merge
conflict in the diff with an IDL IID change. Carrying forward glazman's review
and module owner approval. Asking Bienvenu for an sr.

Comment 25

[Neil Deakin]

The layout changes were actually part of bug 181105. Also, bug 220157 should be
fixed by them as well.

Attachment: final editor patch

I made a minor change to nsTextDocumentServices to use a weak reference to the
editor object instead of a strong reference to prevent a circle. 

Carrying forward the reviews.

Comment 27

[Scott MacGregor]

Attachment: updated spell checker patch

removed more dead code, add more comments about the purpose of the remaining
methods, added more argument null pointer checks. 

This patch is now ready to start the review process. Future issues with the
behavior (I'm sure there will be many) can be handled in separate bugs.

updated spell checker patch 

It helps if I actually specify a reviewer name in the super review box....

updated spell checker patch 

a bunch of nits which you can ignore if you want...

+  NS_ENSURE_ARG_POINTER(aEnabled);
+  *aEnabled = mSpellCheck ? PR_TRUE : PR_FALSE; 
+  return NS_OK;

this could be *aEnabled = mSpellCheck != nsnull;

+      // spell check the text at the previous caret position, but no need to
+      // check the quoted text itself.

why don't we need to spell check the quoted text? Is that what other in line
spell checkers do?

+    case kOpUndo:
+    case kOpRedo:
+      // XXX handling these cases is quite hard -- this isn't quite right

you might say what's not quite right. I guess we need to spell check in case
undoing/redoing (re)introduces misspelling(s).

naming convention style nit:

+      nsAutoString parenttagname;
+      parentelement->GetTagName(parenttagname);
+
+      if (parenttagname.Equals(NS_LITERAL_STRING("blockquote"),
nsCaseInsensitiveStringComparator()))

parentTagName

similarly for

+      const PRUnichar *textchrs = textblock.get();
+      PRInt32 textlength = textblock.Length();
and there are a few others, like currentrange, checkrange, etc...

+  nsCOMPtr<nsISelection> spellCheckSelection;
+  rv = selcon->GetSelection(nsISelectionController::SELECTION_SPELLCHECK,
aSpellCheckSelection);
+  return rv;

can just return selcon->GetSelection...

+  selection->GetFocusOffset(&mCurrentSelectionOffset);
+
+  return NS_OK;

maybe can just return selection->GetFocusOffset(), though maybe you just want
to always return NS_OK...

+  PRBool done, isMispelled;

should be isMisspelled :-)

Comment 31

[Scott MacGregor]

all three patches have been checked in. Marking fixed. I'll treat inline spell
check behavior issues in individual bugs going forward. 

Comment 32

[Michael Kunz]

I just tested 1.8b1 and this version doesn't skip quoted text during spellcheck.
So I tested the oldest available nightly of 15th February and the newest nightly
of 1st March. In both versions the spellchecker doesn't skip the quotes.

Then I tested 1.8a6. This version does still skips the quotes. Therefore I think
the bug came back between the release of 1.8a6 and 15th February.

The patch for this bug was checked in during this period. There were not much
other checkins in editor. Is it possible, that the patch effected the skipping
of quoted text?

Comment 33

[Michael Kunz]

Someone tested some older Seamonkey-Tinderbox-Creature-Zip-Builds for me.
Result:
2005020111 -- quoted text is not checked
2005020118 -- quoted text is checked

So it appears to prove true, that this patch causes this behavior.

Should I open a new bug, or will this patch be fixed here?
