Bug 47712 – Match the elements supported by execCommand('formatBlock') and queryCommandValue('formatBlock')

• Component: HTML Editing
• Status: RESOLVED FIXED

[Ryosuke Niwa]

isElementForFormatBlockCommand and FormatBlockCommand::isElementToApplyInFormatBlockCommand both determine elements used in FormatBlockCommand.  We should merge these two functions into one.

If the behavior here is not changing, I suggest landing the new test first, then the code change. But if the behavior is changing, then it’s great to land them together.

I read this over and over again and could not figure out if the change log was saying this was refactoring only or a bug fix. If it’s a bug fix, then the wording should emphasize the behavior change and then go on to mention the code structure, rather than describing it the other way around.

The test here includes covers the things that we do support, but what about things we do not support? I would be just as interested in seeing at least some of those test cases too.

> WebCore/editing/FormatBlockCommand.cpp:42
> +inline bool isElementForFormatBlock(Node* node) { return node->isElementNode() && isElementForFormatBlock(static_cast<Element*>(node)->tagQName()); }

Since this function is inside a .cpp file it should be marked static, so it gets internal linkage.

Also, I don’t think this deserves the “all on one line” format. lets use the more typical format.

> WebCore/editing/FormatBlockCommand.cpp:107
>  // FIXME: We should consider merging this function with isElementForFormatBlockCommand in Editor.cpp

You forgot to remove this FIXME.

> WebCore/editing/FormatBlockCommand.h:43
> +    bool didApply() const { return m_didApply; }
>  private:

Our usual style is to leave a blank line before private.
