Passing extra command line arguments to haskell-language-server

[cdsmith]

I find myself in a situation where I'd like to limit the memory usage of haskell-language-server, because it grows over time and ultimately makes the machine unusable if I leave it running too long. Basically, I want to pass +RTS -M10G to haskell-language-server. Unfortunately, it appears I can't add command line arguments in the option for the server executable, and I don't see another way to accomplish it.

I would like an option that allows adding arbitrary command line arguments to haskell-language-server. I don't think limiting memory usage is, itself, important enough to be worth an option, so generic command line args would be better.

Thanks for the suggestion, it makes total sense and other vscode extensions allow something similar, prs welcome! 😄

I'm preparing a pull request for this. serverExecutablePath has a resource scope, but it looks like that's in flux. Should I add the new argument with the same scope, or give it a machine scope? I don't understand the reason for the change.
