Replace ranger with nnn

Not going to add nnn for the below reasons

Though it is very fast compared to ranger, UX is a little awkward and clumsy
- Preview opens as tmux pane (or terminal window)
- This is espcially weird when using as vim plugin
- Preview is not closed when opening a file
  - Seems like this can be resolved using patch, but it requires manual compilation
Integration with devicons requires manual compilation

Configuration

install plugin
(While this installs all the plugin, this is convenient as it checks the version of nnn and installs compatible ones)

sh -c "$(curl -fsSL https://raw.githubusercontent.com/jarun/nnn/master/plugins/getplugs)"

fish

set --local preview_tui_key p
# start with preview
alias nnn="nnn -P$preview_tui_key"
# `a`: preview-tui requires fifo
# `e`: nnn does not open file without this
# `H`: display hidden files by default
set --export NNN_OPTS aeH
set --export NNN_PLUG "$preview_tui_key:preview-tui"
# preview-tui
set --export NNN_BATTHEME 'Monokai Extended' # seems not working

nvim

use {
  "luukvbaal/nnn.nvim",
  cond = function() return vim.fn.executable('nnn') end,
  config = function()
    local builtin = require("nnn").builtin
    require("nnn").setup({
      picker = {
        -- should not use tmux here as it will be nested tmux and fail to preview
        cmd = "nnn -Pp",
        style = {
          width = 0.95, -- percentage relative to terminal size when < 1, absolute otherwise
          height = 0.9,
        }
      },
      mappings = {
        { "<C-t>", builtin.open_in_tab }, -- open file(s) in tab
        { "<C-s>", builtin.open_in_split }, -- open file(s) in split
        { "<C-v>", builtin.open_in_vsplit }, -- open file(s) in vertical split
        { "<C-p>", builtin.open_in_preview }, -- open file in preview split keeping nnn focused
        { "<C-y>", builtin.copy_to_clipboard }, -- copy file(s) to clipboard
        { "<C-w>", builtin.cd_to_path }, -- cd to file directory
        { "<C-e>", builtin.populate_cmdline }, -- populate cmdline (:) with file(s)
      }
    })
    vim.keymap.set('n', '<Leader>e', "<Cmd>NnnPicker<CR>", { desc = "nnn" })
  end,
}
