Add option to not rendering specific git icon if the icon is explicitly not provided

[alex35mil]

Is this a question?
It is not.

Can this functionality be implemented utilising API?
AFAICT it's not possible with the current API.

Is your feature request related to a problem? Please describe.
I'm trying to hide some specific git icons in the tree, but looks like it is not possible.

git = {
    unstaged = "", -- renders empty clolumn
    unmerged = nil, -- renders default icon
    untracked = false, -- raises
}

Describe the solution you'd like
Don't render anything if the icon value is not an icon.

Describe alternatives you've considered
none

Additional context
none

What is that you expect to happen exactly? You want to achieve "dont render anything", but setting "" "renders empty column", isn't it what you want?

How about nvim-tree.renderer.icons.glyphs.git.unstaged=" "?

[alex35mil]

@gegoune In the case of empty string, it looks like this:

✓ staged.file
✓ staged.file
✓  staged.file.with.empty.column
✓ staged.file

I want to get rid of this space before staged.file.with.empty.column entry.

[gegoune]

vim-tree.renderer.icons.glyphs.git.unstaged="" removes the icon for me and does not render anything at all.

nvim-surround.lua has staged changes
nvim-tree.lua has unstaged changes

@gegoune Could it be that this ghost space appears only when there is one icon with actual value rendered, but there is also another one applied with the icon set to an empty string?

@gegoune Reproduced:

[alex35mil]

Config:

git = {
    staged = "✓",
    deleted = "",
    renamed = "➜",
    unstaged = "",
    unmerged = "",
    untracked = "",
    ignored = "",
},

Statuses:

This might be a double width character issue. nvim lua isn't great at detecting and handling such cases.

Possible hacky workaround: find an empty or space double width character.

[alex-courtis]

It looks like it's actually a padding issue: when there are multiple git icons, icons.padding is inserted in between.

This is fine for files that are just staged "✓"
It's a problem when it's staged and unstaged "✓" .. " " .. ""

@alex35mil I would be most grateful if you tested this fix:

cd /path/to/nvim-tree.lua
git pull
git checkout 1923-allow-empty-git-icons
