git submodule icons in nvim-tree

[adimail]

This feature idea was originally discussed here: Does nvim-tree have webicon for git submodules?.

Raised a similar issue in #3038

Should this go into nvim-tree itself?

Proposed Solution

Allow users to define a custom icon for Git submodules in the renderer.icons.git configuration. For example:

renderer = {
    -- other configurations...
    icons = {
        -- other icons...
        git = {
            -- existing git icons...
            submodule = '',  -- Git submodule icon
        },
    },
},

It would be helpful to have a dedicated icon for Git submodules in the nvim-tree file explorer. Currently, while nvim-tree supports various Git status icons (e.g., staged, unstaged, untracked), there isn’t an option to display a unique icon for submodules.
