A File Explorer For Neovim Written In Lua

Notice

This plugin requires neovim >=0.5.0.

If you have issues since the recent setup migration, check out this guide

Install

Install with vim-plug:

" requires
Plug 'kyazdani42/nvim-web-devicons' " for file icons
Plug 'kyazdani42/nvim-tree.lua'

Install with packer:

use {
    'kyazdani42/nvim-tree.lua',
    requires = 'kyazdani42/nvim-web-devicons',
    config = function() require'nvim-tree'.setup {} end
}

Setup

Options are currently being migrated into the setup function, you need to run require'nvim-tree'.setup() in your personal configurations. Setup should be run in a lua file or in a lua heredoc (:help lua-heredoc) if using in a vim file. Note that options under the g: command should be set BEFORE running the setup function.

-- following options are the default
require'nvim-tree'.setup {

  -- hijack netrw window on startup

KeyBindings

Default actions

<CR> or o on .. will cd in the above directory
<C-]> will cd in the directory under the cursor
<BS> will close current opened directory or parent
type a to add a file. Adding a directory requires leaving a leading / at the end of the path.

you can add multiple directories by doing foo/bar/baz/f and it will add foo bar and baz directories and f as a file
type r to rename a file
type <C-r> to rename a file and omit the filename on input
type x to add/remove file/directory to cut clipboard
type c to add/remove file/directory to copy clipboard
type y will copy name to system clipboard
type Y will copy relative path to system clipboard
type gy will copy absolute path to system clipboard
type p to paste from clipboard. Cut clipboard has precedence over copy (will prompt for confirmation)
type d to delete a file (will prompt for confirmation)
type ]c to go to next git item
type [c to go to prev git item
type - to navigate up to the parent directory of the current file/directory
type s to open a file with default system application or a folder with default file manager (if you want to change the command used to do it see :h nvim-tree.setup under system_open)
if the file is a directory, <CR> will open the directory otherwise it will open the file in the buffer near the tree
if the file is a symlink, <CR> will follow the symlink (if the target is a file)
<C-v> will open the file in a vertical split
<C-x> will open the file in a horizontal split
<C-t> will open the file in a new tab
<Tab> will open the file as a preview (keeps the cursor in the tree)
I will toggle visibility of folders hidden via |g:nvim_tree_ignore|
H will toggle visibility of dotfiles (files/folders starting with a .)
R will refresh the tree
Double left click acts like <CR>
Double right click acts like <C-]>

Settings

The list option in view.mappings.list is a table of

-- key can be either a string or a table of string (lhs)
-- cb is the callback that will be called
-- mode is normal by default
local list = {
  { key = {"<CR>", "o" }, cb = ":lua some_func()<cr>", mode = "n"}
}

These are the default bindings:

local tree_cb = require'nvim-tree.config'.nvim_tree_callback
-- default mappings
local list = {
  { key = {"<CR>", "o", "<2-LeftMouse>"}, cb = tree_cb("edit") },
  { key = {"<2-RightMouse>", "<C-]>"},    cb = tree_cb("cd") },

}

You can toggle the help UI by pressing g?.

Tips & reminders

you can add a directory by adding a / at the end of the paths, entering multiple directories BASE/foo/bar/baz will add directory foo, then bar and add a file baz to it.
