Not sure how to work around this, I can't find a way to chain ChildProcess since then is only available on Promise. Alternatively, we could make a spawn with a wait to make sure this doesn't take too long. Ideas?

there is already dependency on promisify-child-process which provides a promisfied equivalents of child_process, did you check it?

I think I did? Doing .then on ChildProcessPromise was only returning Promise<Output> and not sure of there is a way around it really.

As long as we use raw child_process stuffs (without writing a wrapper) there's no way to do that (get stdout wrapped by Promise if success, and Promise failed if return code isn't 0).

Doesn't look like it :/ We want to pipe the output from coursier to VS Code output, but it seems I can do it only via ChildProcessPromise. I tried returning a Promise, but that seems to have a wrong type in the actual javascript underneath:

Och actually if I have an intermediate object it works, not 100% pretty, but feels ok.

[note]
I thought this might fail to detect windows when it's 64bit system, but it looks like there's only win32 😄

I'm not sure this work for Windows (while CI tests pass), maybe it's Path instead of PATH on windows?

PATH works, the CI actually checks this correctly. https://superuser.com/questions/441611/what-is-the-linux-equivalent-of-windows-path

Why do we need these changes?

otherwise it's not possible to start the extension inside VS Code, I can move it separate, but this is just a follow up from the PR that merged the language client

Maybe we want to use https://github.com/otiai10/lookpath to find commands from PATH, this library deals well with the platform differences (and it takes care of PATHEXT to checking cs.bat and cs.exe)

Hmm... I would add the library if we see any issue, but this seems to work correctly both in linux and windows.

Also it seems that the alst release was in 2021 so I would rather tweak our logic if needed.

This might help out in corporate environements since it will require installing coursier only once and Metals will be able to use it. In later steps I will try to automatically download coursier or native image via metals if not available.
