Feat: git worktree component

[OscarCreator]

Requested feature

Add worktree component https://github.com/nvim-lualine/lualine.nvim/blob/master/doc/lualine.txt#L240

Motivation

When using a bare git repo with multiple worktrees it would be useful to see which worktree you are currently on.

It works with the branch component for me. Can you include some steps to reproduce your issue?

This is what has worked for me:

1. git clone --bare https://github.com/nvim-lualine/lualine.nvim && cd $_ Now we have a bare repo of lualine.nvim
2. git add worktree test_work_tree master Create a worktree on branch master
3. nvim README.md

If this is not what you desire, let me know I'm happy to help! 😀

The worktree I mean in this case is test_work_tree. So a way to display that folder name is what I am after.

Something like this could the status bar look like:

NORMAL | master | test_work_tree | README.md

It can be evaluated with:

function() 
    local res, match = vim.fn.FugitiveGitDir():gsub(".*worktrees/", "")
    if match == 1 then 
        return res 
    else 
        return "" 
    end 
end

Something like this?

I have maintained the same icon as the branch because I'm unable to find a specific symbol for worktrees.

[OscarCreator]

Yes something like that. I have to see if I can find a symbol for it, otherwise it can just be changed (or removed) at a later time.
