While find/replacing in VSCode across many files formatting save takes a long time and bungles replace. #815

I did a search/replace in VSCode for "Core" to "Dashboard" across many files (200~) and VSCode hangs while letting Lexical format it. This also seems to result in future search/replace issues as a replace of Core.AccountAuth to Dashboard.AccountAuth turns Core.AccountAuth, :ensure_authenticated into Dashboard.AccountAuthure_authenticated. While the below screenshot shows them being saved each "save" takes ~3s and actually finishes (it's not locked up). That said the file is already saved, regardless of what the indicator says.

I've been able to replicate this, going to play around with this a bit and see if I can make this perform better.

This happens to me frequently as well. I have the format on save setting enabled and Lexical seems to be formatting the file and rebuilding the application for each saved file.

I wonder if it would make sense to have some kind of "debounce" to delay the application rebuild for a few milliseconds after saving a file. This way it would be triggered only after saving all the files instead of once for every file.

The build presently already has a debounce, but format doesn't. Things get a little tricky with debounces, because format requests expect a response within some amount of time, and they operate on an unsaved document. Thus, if you miss that window, there's no way that I know of to actually format the document.

@krainboltgreene @crbelaus can you check out the branch in #826, and see if that helps?

krainboltgreene commented 1 month ago

Will do.
