"Go to Symbols in Workspace" is too slow in VSCode with Lau extension by sumneko

[gohilurvish]

I am working on project where there are are roughly 5000+ lua files.

I am using VSCode (moving from Sublime) with extension Lua by sumneko. While all the other things are working well, what I see a huge drawback is the symbol search in workspace.

When I start typing a function name, it take like good 10-15s for it to show results. And any incremental char in the search field also takes some 10-15s. In Sublime it used to be fast even without any extension (VS code doesn't do it work without extension).

Has anybody faced this? Are there settings which can cache the result and show it faster?

Or any other extension which can do this better way?

PS: I posted this on reddit under r/lua but found this place later which looks more closer to the issue

most of its logic runs at the Lua layer. Therefore, it is not suitable for running in larger projects. Perhaps turning off workspace diagnostics might improve performance to some extent.

Additionally, I recommend you try EmmyLua. It is a native(C# AOT compilation) Lua language server.

Thank you for the reply @CppCXY !
I did gave a try to EmmyLua earlier and the issues I observed are as follows:

• It adds inline suggestions which is disturbing (attached is image for reference and it is not limited to it)
• When loading the repo first or after saving a file, it start analyzing and it take long. Like 20-30min.
• There are no setting at all which can help to disable any of the above issues.

It works great for suggestion and code completion though.

Based on your description, it seems that you might not be using the latest version, because on my own computer, scanning a project with 3,000 files takes less than 10 seconds in total.

If you're interested, you can go to the EmmyLua repo and report the issue

Not a bad idea. Let me.
Meanwhile, I have started exploring ctags which is making the workspace symbol search easy.
