Bug 104970 – Web Inspector: Search by selection

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[johnjbarton]

Browsers provide word-selection upon double click on text. They also provide arbitrary contiguous text selection with the mouse. We can leverage this feature in search by loading the search query with the text selection when ever it is available.

The user experience here is similar to other editors, for example Sublime Text.  For me this feature is the most important one missing from Web Inspector's editor.

Patch to follow.

I'll add a test if the patch would be accepted with one.

Looks good, style nits inline.

> Source/WebCore/inspector/front-end/AdvancedSearchController.js:246
> +    syncToSelection: function()

Rename to _syncToSelection (make private)

> Source/WebCore/inspector/front-end/AdvancedSearchController.js:249
> +        if (selection.type === "Range" && !selection.isCollapsed)

We typically do if (selection.rangeCount)

Pavel, will platform selection always work properly in text editor?

> Source/WebCore/inspector/front-end/AdvancedSearchController.js:250
> +            this._search.value = selection.toString();

selection.toString().replace(/\r?\n.*/, "") to make sure search query does not have any line feeds.

Just so I understand:  private-per-file not per-class ? The function is call is across classes.

Yes. Private is per class. It is not a compiler annotation, it is rather an indication that you can rename it within file. We also are supposed to follow the file per public class policy.

Since the syncToSelection() is across classes I left it unprefixed with _.

The test here is minimal, only the positive single word case.  Multiple line selection works -- puts the first line in the input -- but I don't know how to set the selection to test this.  Random content in the selection buffer should also be tested in principle, but in my experience so far WebInspector already clears selections. Anyway the test file is set up for more cases if we encounter problems.

Weird indent.

You could change from (or to) line number that is passed to the TextRange constructor.

I know this bug is closed, I'm just storing some observations here regarding your question.

When in the Sources panel on a breakpoint I can select a Scope Variable and hit search, the selected scope variable is the query.  

Yay! This is behavior we want.
