Develop: Go layer tools doesn't work

[vbauerster]

Description

It seems that Go's layer tools don't see a $GOPATH env variable.
I came to this conclusion, because none of the Go tool is working, on develop branch: 8754b24

Everything was working here: 7944ed2

Reproduction guide 🪲

• Start Emacs
• Open any go file with imports from std lib.
• Turn on syntax checking SPC t s

Observed behaviour: 👀 💔
All imports of std lib are error highlighted, saying package not found.

Expected behaviour: ❤️ 😄
Import of std lib packages should always be found and not error highlighted.

This is because of the new env-vars cache. The solution for this is to open the .emacs.d/.cache/.env-vars file and manually set GOROOT and GOPATH there.

This is probably going to be fixed, syl20bnr is already aware that it's buggy.

@ljupchokotev I don't have a file in .emacs.d/.cache/.en-vars. Perhaps it was never created since i started from a clean install on the dev branch? What do the contents of that file look like? I don't mind editing it manually to get the go layer working while I wait for this to be patched.

@patrick-motard Check the documentation about environment variables in Spacemacs. You can initialize that file yourself.

@ljupchokotev I'm not seeing anything in DOCUMENTATION.org regarding this file or how to initialize it, nor environment variables except for a brief mention of SPACEMACSDIR. Is there another location for documentation where I should be looking?

@patrick-motard, make sure you are looking at the documentation for the develop branch: https://github.com/syl20bnr/spacemacs/blob/develop/doc/DOCUMENTATION.org#environment-variables-and-path

I think ljupchokotev was referring to .spacemacs.env. The related key bindings are SPC f e e to edit .spacemacs.env, SPC f e C-e to re-initialize it from the current environment, and SPC f e E to reload it.
