Extension development not working?

[TheOddler]

Your environment

Which OS do you use:

NixOS 23.05, VSCodium installed with HomeManager

Steps to reproduce

1. Clone this repo
2. Change something (I for example changed the Finding haskell-language-server message to HEY Finding haskell-language-server)
3. Press F5
4. The new editor shows up
5. It doesn't have the updated extension (In my case still just shows Finding haskell-language-server in the console, without the extra HEY)

I also tried just removing the extension from my global install, and if I then press F5 to test I still have no Haskell extension installed.

Expected behaviour

Get the updated extension for testing

Actual behaviour

I just have my normal setup, so I cannot test my changes to the extension :(

Hi, thank you for your bug report!

I am using the described workflow for development.

Building locally succeeds? E.g., yarn install; yarn run test?

Perhaps you have some logs to share, too?

[TheOddler]

Building does not work, I'll have a closer look tonight if I remember (as I'm working right now), but just running yarn install; yarn run test gives me:

The file /home/pablo/Dev/vscode-haskell/.vscode-test/vscode-linux-x64-1.80.1/code does exist though:

You are on NixOS right? Does the provided nix expression work?

[TheOddler]

I am, thought I didn't realise there was a provided nix expression :o

So getting different errors now:

❯ nix-shell

... and lots more of that

Oh, but when I run that again, the timeout error changes back to the original:

I checked on my nixos machine, nix-shell followed by yarn install succeeds and then I can open vscodium and press f5 to develop the extension.

[TheOddler]

Hmm, that's annoying that it doesn't for me :( I'll try again, see if I can figure it out. Thank you for checking though!

[fendor]

I just realised, the tests rely on ghcup to be on the path and usable, so it is no surprise that yarn run test doesn't work on NixOS out of the box.
