Does this also resolve #5674?

Yes.

these are used at 2 places should we create another method as this looks like the reusable code.

should we reset regex lastIndex above this line just to reset it?
re.lastIndex = 0;

Yes, see: https://stackoverflow.com/a/4724920

Sorry, I wasn’t focused earlier.

No need, because it’s already set in multiLineBackwardMatch.

Hey @sekedus
Do you have time for writing test cases for the changes as well?

@sekedus some test case requirement is failing will you be able to resolve this?

Sorry, I don't know where the error is and how to resolve it.

Any suggestions?

src/editor.js

+
+        // Updates "updateCounter" and "ace_nomatch" in the search box
+        if (this.searchBox && this.searchBox.active === true)
+            this.searchBox.find(false, false, true);


Could you please move this to an input event handler in searchbox, something like editor.on('input', this.$onEditorInput) and remove the listener when deactivating. onDocumentChange can be called multiple times during one edit, and input event debounces that with a timeout.
Also in one of tests add a scenario of changing editor value, e.g.

editor.insert("searchedText") setTimeout(function() { // verify that search counter have been updated }, 50)

to prevent coverlay complaining about untested lines

nlujjawal · 2024-11-28T13:26:34Z

@sekedus The failure of checks is due to some lines of code not having test cases.
You can view in this link about those lines https://github.com/ajaxorg/ace/pull/5675/checks?check_run_id=33534340733.
