Bug 161514 – Web Inspector: Change Cmd-D from kill line to selecting next occurrence

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

I often find that when I want to edit the same value in CSS for multiple rules, I try to use Cmd-D to select multiple occurrences (like Sublime Text), but it will delete the line instead.

Chrome DevTools do the same as Sublime Text.

In Xcode, Command-D does nothing for text and duplicates an item in Interface Builder.

Sounds fine to me. As Nikita said, Cmd-D does not have any system-wide significance. The more cross-platform (emacs binding) way to kill a line is Ctrl-K.

The rebinding is fine but I cannot tell what the other effects of this patch are.

I really wish we had a test that dumped out the normalized key map so we could see concretely what keybindings change when we add a new extension like this. It introduces a ton of new bindings, some of which might conflict (or not).

Do you think you could write such a test?

EDIT: filed https://bugs.webkit.org/show_bug.cgi?id=161536. This is out of scope for this change since it depends on UI tests probably.

Please add this to:
Source/WebInspectorUI/Scripts/update-codemirror-resources.rb

So when we update CodeMirror (I tend to use that script) we get any updates to this file as well.

r=me but please address comments prior to landing.

> -            "Cmd-D": this._handleTextKillCommand.bind(this, "deleteLine", false),

Later in this file, there is a comment that talks about Cmd-D.

            // An entire line was deleted, including newline (Cmd-D).
            if (change.removed[0].length && !change.removed[1].length) 
                killedText = change.removed[0] + "\n";

I think we should just leave this code in and replace 'Cmd-D' in the comment with 'deleteLine'. If we re-add the command as a different keybinding, it's unlikely someone will know that this code needs to be changed, and the actual logic does not depend on the particular keybinding, obviously.

I am not familiar with CodeMirror key maps. Do we inherit any other bindings from sublime.js, or just this one that we requested?

AFAICT, it seems like we only inherit that specific binding.
