fm.nvim

A vim-vinegar like file explorer that lets you edit your filesystem like a normal Neovim buffer.

Fork from oil.nvim

Requirements

• Neovim 0.8+
• (optional) nvim-web-devicons for file icons

Installation

fm.nvim supports all the usual plugin managers

lazy.nvim

{
  'nvim-jo/fm.nvim',
  opts = {},
  -- Optional dependencies
  dependencies = { "nvim-tree/nvim-web-devicons" },
}

Packer

require('packer').startup(function()
    use {
      'nvim-jo/fm.nvim',
      config = function() require('fm').setup() end
    }
end)

Quick start

Add the following to your init.lua

require("fm").setup()

Then open a directory with nvim .. Use <CR> to open a file/directory, and - to go up a directory. Otherwise, just treat it like a normal buffer and make changes as you like. Remember to :w when you're done to actually perform the actions.

If you want to mimic the vim-vinegar method of navigating to the parent directory of a file, add this keymap:

vim.keymap.set("n", "-", "<CMD>FM<CR>", { desc = "Open parent directory" })

You can open a directory with :edit <path> or :FM <path>. To open fm in a floating window, do :FM --float <path>.
