ftplugin/go/tagbar.vim breaks tagbar ctags for files arguments for nvim CLI

[chrisplo]

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

Started nvim with a .go file as an argument, then opened Tagbar.

What did you expect to happen?

To see ctags for go file in tagbar just like when starting nvim without arguments, then opening .go file.

What happened instead?

no tags shown. If I rm dein/.cache/init.vim/.dein/ftplugin/go/tagbar.vim -> /Users/chrisplo/.cache/dein/repos/github.com/fatih/vim-go/ftplugin/go/tagbar.vim then the tags will be seen.

If I rm dein/.cache/init.vim/.dein/ftplugin/go/tagbar.vim -> /Users/chrisplo/.cache/dein/repos/github.com/fatih/vim-go/ftplugin/go/tagbar.vim then the tags will be seen. What does that mean? What are you removing? What's the -> represent?

no tags shown.

I'm unable to duplicate what you're describing here. When I start vim or neovim with a file argument and then open tagbar, the tags are shown fine.

[chrisplo]

it's a symlink (on left) to target (on the right), I presume dein is adding the symlink as part of how it installs vim-go's ftplugin for go.

This seems like it's something specific to your environment, but I'm not quite sure what it is. I'd recommend that you try duplicating this issue without dein. If you can create some clear replication steps and isolate the problem to vim-go, I'll be happy to help out. If the problem is specific to dein somehow, then this will be an issue for you to solve.
