Bug 45709 – Need to remove autocorrection underlines in current line when newline is entered.

• Component: HTML Editing
• Status: RESOLVED FIXED

[Jia Pu]

In Bug 44958, we added blue underline on autocorrected words. To be consistent with the behavior in NSTextView, we need to remove autocorrection underline in current line when a newline character is inserted.

This is the wrong level for this code. I am almost certain we don't want to removal of markers tied specifically to the code path that handles hitting the newline key.

Enrica, maybe you can help Jia find the right place for this?

[Enrica Casucci]

I think the right place to do this is TypingCommand. Look at the doApply method, that is where we handle special characters such as delete, enter, backspace, etc.

There is no way to test this?

I think you can test this given the tests in:
http://trac.webkit.org/browser/trunk/LayoutTests/editing/spelling

Take a look at http://trac.webkit.org/browser/trunk/LayoutTests/editing/editing.js for how to insert a line break from the script.

Won’t the call in respondToChangedSelection already take care of this? It doesn’t make sense to me that these calls need to explicitly be done by the typing command machinery.

If I understand the code correctly, respondToChangedSelection() is called on every text insertion. However the behavior we want (which is consistent with AppKit) is clearing the markers only when a line break is inserted. 

That said, please let me know if this can be done in respondToChangedSelection().

Why do we want this behavior on all platforms?  If you're trying to match WebKit's behavior with AppKit, shouldn't we just doing that for Mac platforms?  Also, I'm not even sure clearing markers only when a line break is inserted is an obvious improvement on Mac.

This is in effect Mac only, since on non-Mac platform, the said marker doesn't get added  in the first place. However, I can certainly bracket the removal code with ifdef's if it's desirable.

The goal of this patch is to bring WebKit into parity with other UI on Mac. To further improve this design is probably outside of the scope of this patch.

I was referring to the code you added to respondToChangedSelection. But it seems that code removes the marker from the first word in the selection and is not related to the removal when inserting a line break.

I still don’t understand why the code is tied to editing operations. Typically hitting return and pasting in a return character would do the same thing. Is it correct that pasting in a return character would not remove the marker even though hitting the return key would?

The rest looks good.

There is no need to use oldSelection, oldSelectionStart and newSelectionEnd. You can simply do:
if (!inSameParagraph(m_frame->selection()->selection().visibleStart(), newSelection.visibleEnd()))
and remove the three lines above.
