No AST for new files #2487

Closed CalebLarsen closed 5 years ago

CalebLarsen commented 5 years ago

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

Frequently I will make a new go file or read somebody else's code, and then attempt to use :GoDef on functions and have the function fail. The error I get is that there is no AST for that file. I've tried to search how to resolve this issue and have not found any resolutions (although I found another soul on reddit had similar issues).

Try creating new files, or copy a file from Github and immediately running :GoDef

What did you expect to happen?

I expected to see the function definition

What happened instead?

I received an error of "vim-go: no AST for file:///path/to/file.go"

Configuration (MUST fill this out):

Vim in Tmux using Alacritty (I hope this is what you are wanting here)

The default for g:go_def_mode is gopls, which requires that the file is on disk, so just save the file before trying to jump to a definition.

This will be remedied in a future version of gopls.

Alternatively, if you're in GOPATH mode, then you can set g:go_def_mode to godef or guru.

hellodudu commented 5 years ago

Same problem, using godef can solve this. But it's much more slower when jumping.
