gopls functionality doesn't when GOPATH should be detected

[dhduvall]

What did you do? (required. The issue will be closed when not provided.)

I have let g:go_autodetect_gopath = 1 in my ~/.vimrc, which does a fine job of figuring out what $GOPATH should be set to in my workspace. Then I use one of the functions that uses gopls, such as autocomplete.

The issue seems to be that the BufEnter autocmd that sets $GOPATH based on the autodetected value runs after gopls is launched (from the FileType autocmd in the vim-go augroup, if I'm reading this correctly). If I start vim with $GOPATH already set correctly, everything seems to work correctly.

Perhaps I need to move away from using g:go_autodetect_gopath, but I'm not sure what mechanism I'd use to set $GOPATH (I don't want or need to set it generally outside vim, and it's potentially different for different workspaces).

What did you expect to happen?

Get correct autocomplete results.

What happened instead?

Get back nothing. :messages shows

vim-go: [completion] FAIL
vim-go: no matches

Thank you for the report @dhduvall . This may be a fairly easy fix. I'll get to it as soon as I can, but there are some caveats that might complicate some use cases.

FWIW, I use https://direnv.net/ to manage these kinds of things so that even go build at the commandline will work.

Does #2255 resolve this for you?

[dhduvall]

Yes, it does; thank you!
