Folder name specific colors

[antoniosarosi]

Is this a question?
Original Q&A: #1498

Can this functionality be implemented utilising API?
I don't think so, I haven't found any function to change the color of an icon.

Is your feature request related to a problem? Please describe.
It's not related to a problem or bug, the feature would simply allow the user to change the color of a directory icon based on its name, for example, "node_modules" = "green", "lua" = "blue", etc.

Describe the solution you'd like
Either a setup option similar to nvim-web-devicons:

require'nvim-web-devicons'.setup {
 override_by_filename = {
  [".gitignore"] = {
    icon = "",
    color = "#f1502f",
    name = "Gitignore"
  }
 };
}

Maybe something like this:

require("nvim-tree").setup({
    renderer = {
        indent_markers = {
            enable = true,
        },
        override_by_directory_name = {
            ["node_modules"] = {
                icon = "󰎙",
                color = "#68A063",
                name = "NodeModules",         
            }
        }
    }
})

Or some sort of API function that gets called with the directory name and returns the color (not sure how that would work or how it would impact performance).

Describe alternatives you've considered
I tried configuring nvim-web-devicons directly but I think you can only to that with files, not directories.

Additional context
Basically trying to simulate icon themes like Material Icon Theme for VScode:

[alex-courtis]

This can be done. We can match the folder based on nvim-web-devicons name.

Something like M.devicons.get_icon(node.name, node.extension) in icons.lua get_folder_icon

The icon and colour would be provided from overrides in nvim-web-devicons

Pull requests are always gratefully appreciated.

My initial notes around highlight groups were for folder colour, however as that is not needed, this much simpler solution is appropriate.

You mean here? I'll try to implement it myself and submit a PR. I don't know much about Lua but seems to be a simple language.

That would be grand. Please add a default off option to enable this behaviour: renderer.icons.webdev_colors_folder to control this behaviour.

Famous last words.
