1 year ago There is a performance issue with default word selection. I didn't measured it but it seems like it's SelectWordUtil.getWordOrLexemeSelectionRange: it calls EditorActionUtil.isLexemeBoundary in a cycle. Every EditorActionUtil.isLexemeBoundary does lexing from scratch: creates lexer, iterates over it and so on:

UPDATE:
If we put injected JS code in a separate .js file the performance is OK so it's an issue with an injected code.

1 year ago @PassingByThs could you confirm that it's an issue with injected (JS in HTML) code? Does the same JS code but in separate .js file work fine for you?

1 year ago In the scenario I encountered, it seems like that this issue only occurs in injected (JS in HTML) code. It works fine in separate .js file.

1 year ago EditorActionUtil.isLexemeBoundary calls EditorEx.getHighlighter which implementation is different for regular (EditorImpl) and injected (EditorWindowTrackerImpl.EditorWindowImpl) code. First one reuses the the highlighter, second one creates new highlighter on every call.
But word selection for an injected Java code works fine even with the same behavior. Further investigation is required.

11 months ago Is there another way to avoid this prompt? Or is it possible to provide some configuration switches to avoid this prompt by disabling certain features?

11 months ago @PassingByThs I don't think so. The prompt is just a progress-bar for Word Selection action. The action takes too much time so the prompt is visible. All we can do is just to wait until it will be fixed from JetBrains side.
When double click or press CTRL + W on java script method name in HTML file, IDEA pop up a progress window which display "Selecting word at given offset..."
