A File Explorer For Neovim Written In Lua

Notice

This plugin doesn't support windows.
This plugin requires neovim nightly.
You can switch to commit afc86a9 if you use neovim 0.4.x.
Note that the old version has less features and is much slower than the new one.

Install

Install with vim-plug:

" master (neovim git)
Plug 'kyazdani42/nvim-web-devicons' " for file icons
Plug 'kyazdani42/nvim-tree.lua'

" old version that runs on neovim 0.4.x
Plug 'kyazdani42/nvim-tree.lua', { 'commit': 'afc86a9' }
" for icons in old version
Plug 'ryanoasis/vim-devicons'

KeyBindings

move around like in any vim buffer
<CR> on .. will cd in the above directory
<C-]> will cd in the directory under the cursor
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 x to add/remove file/directory to cut clipboard
type c to add/remove file/directory to copy 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
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:lua_tree_ignore|
H will toggle visibility of dotfiles (files/folders starting with a .)
R will refresh the tree
gx opens the file with the open command on MACOS and xdg-open in linux
Double left click acts like <CR>
Double right click acts like <C-]>

Note

This plugin is very fast because it uses the libuv scandir and scandir_next functions instead of spawning an ls process which can get slow on large files when combining with stat to get file informations.

The Netrw vim plugin is disabled, hence features like gx don't work across your windows/buffers. You could use a plugin like this one if you wish to use that feature.

Features

Open file in current buffer or in split with FzF like bindings (<CR>, <C-v>, <C-x>, <C-t>)
File icons with nvim-web-devicons
Syntax highlighting (exa like)
Change directory with .
Add / Rename / delete files
Git integration (icons and file highlight)
Indent markers
Mouse support
It's fast
