How to auto-format code?

[aryairani]

I have ormolu selected in settings:

but when I run the Format Document action:

it doesn't work:

and it suggests I install another extension. Am I using the wrong action?

It should work with HLS. Just for clarification, you are using HLS and not ghcide?

[aryairani]

Thanks for clarifying — I am using ghcide because using HLS takes a long time to start and then reports seemingly random numbers of false errors for my project on startup (a different, seemingly random number on each startup); I haven't been able to get it to work at all. I have been using the ghcide variant setting because it was the only one that worked.

I do see that if I switch back to HLS and restart the extension host ("Restart Haskell LSP server" isn't enough), that it will format with ormolu as expected, though, despite the reported errors.

The start-up time should be about the same for ghcide and hls.
About the random false errors, could you show us a bit about the project and errors if you have time?

Sorry I dropped the ball on this. I’ll still try to return to it.

@aryairani hi, have you the chance to try it out again and provide some info if it does not work?

[andys8]

Issue could be renamed. Author confirmed formatting is working with his. Now the topic is about "potential false errors".

@andys8 thanks for the suggestion. As it is a totally different issue i will close this one, @aryairani please open a new one if you continue experiencing those errors
