CocTagFunc not working

[Draiken]

I'm attempting to use set tagfunc=CocTagFunc and it doesn't seem to work with Solargraph.
It seems to call getTagList and looking through the code it makes definition calls to the LSP, so this should be present in Solargraph. Calling call CocAction('jumpDefinition') works and AFAICT that's pretty much what the taglist would do.

I'm happy to dig deeper and try to come up with a solution but I'd need some pointers since I just switched over to COC and I'm not familiar with it.

My best guess is that this is a small missing piece (perhaps on the client configuration?).

Seems no definitioin found.

[Draiken]

@chemzqm I'm sorry, what does this mean?

The issue remains. On the same definition, jump to definition works, using the tag navigation does not.

[chemzqm]

jump to definition works, using the tag navigation does not.

Not able to reproduce.

[Draiken]

I attempted to reproduce this with a clean vimrc and indeed it does seem to work. It seems the issue is with my specific configuration.

Thanks for looking into it!

@chemzqm if you could help me, I am puzzled at this.

I tried using a clean CoC install, and it worked with this. I had to manually set the filetype to ruby, then the tag command works.

set nocompatible
filetype off

set rtp=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'neoclide/coc.nvim'
call vundle#end()
filetype plugin indent on
syntax on

set tagfunc=CocTagFunc

If I add back the default /usr/share/vim/vim90 to the runtime path, it stops working

set nocompatible
filetype off

set rtp=/usr/share/vim/vim90
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'neoclide/coc.nvim'
call vundle#end()
filetype plugin indent on
syntax on

set tagfunc=CocTagFunc

This is my vim version

It seems that something in the default vim runtime is breaking this behavior for me. If you can help me in any way, I'd really appreciate it. Thanks!

set rtp=/usr/share/vim/vim90

What is inside the file vim90?

[Draiken]

It's the default vim runtime for vim 9. Basically it's the system's installation which includes what is in this folder from vim's source.

[Draiken]

It might mean that there's a conflict with whatever is being packaged in vim for my Linux installation. Or maybe it's for all installations.

I'm gonna see if I can reproduce this in a docker container

[Draiken]

Okay, I've managed to reproduce this. Something is wrong with the plugin running a default vim installation. I've created a repository with a Docker image reproducing the issue. Instructions are on the README
