Just copy mpi.vim into your plugin directory.

• KISS
• I like vim-devicons. But it cares too much about integrating with other plugins. Its code is huge get such a simple task.(getting file type icons)
• I like to manipulate and discover things and see what's going on under the hood(And i encourage you, too). So, instead of just using a huge plugin, install a minimal alternative and change it according to your needs.

Just call mpi#get(<name of buffer>) to get its related icon. For exmaple use this command to see what'll happen:

:echo mpi#get(expand('%:t'))

You can add unicode emojies like this:

let g:mpi#exact_matches = {
    ...
    \ '.zshrc'                           : '🌍',
    \ '.zsh_history'                     : "\<Char-0x23f0>",
    \ '.fehbg'                           : '🐈',
    ...
\}

Filetypes are here: /usr/share/nvim/runtime/filetype.vim
