Add mini.icons support
Still, it will be good to support mini.icons.
The default is nvim-web-devicons.
Thanks for your PR! However I plan to add a more generic way to allow users to define their own icon provider, not just mini.icons or nvim-web-devicons. Ideally, the provider is a user-defined callback with parameters path and ft and returns an icon and an icon_hl.
@mathjiajia I've pushed changes in commit a1b893c to allow users to customize dir and file icons using opts.icons.kinds.file_icon and opts.icons.kinds.dir_icon. Can you try to implement mini.icons support in the default callback of these two options?
I will reopen a PR
