How can I use go language server?

[134130]

I'm using Go plugin with mise.

When using mise-vscode with the Go plugin, the Go plugin tries to install Go language server, but the below error occurs:

The mise supports auto-setup for go workspace like GOBIN or GOPATH. Can mise-vscode supports to configure the environment variables? Thanks!

I'm currently using with mise use -g [email protected] to avoid the issue, but I still hope the plugin supports settings the environments from the mise.toml on the project root.

Thanks for reporting the issue. Sorry, I did not look into it yet. I likely did not notice the issue as I have a global go version installed.

Sorry for not contributing to this issue, and thank you for replying to this.

@134130 I am not able to reproduce the issue.

I have tried in a fresh Ubuntu VM and could not reproduce the issue. The environment variables are set by mise automatically. It should also configure the VSCode settings.json file with the correct path to go.

There are two cases:

• first one is if you open a go project without go installed. In this case, even if you install go with mise, the go extension won't be usable until you either relaunch VSCode (or use the reload window action). After reloading VSCode, it then works properly.
• the other case, is if you have already set up go before opening VSCode. In this case, it will work directly. This is how I have described it here: https://hverlin.github.io/mise-vscode/guides/golang/

Happy to try again if you have any additional details.

Sorry for my misreading the documents. I opened the project without go installation in global. I understood it as that the vscode process needs to open with go installed environment.

No problem 👍 I will update the documentation to indicate that one might need to relaunch VSCode if the go language server is not not installed properly on the first launch. Ideally, I think the go extension should not fail hard and allow to retry without having to reload the VSCode window.
