A File Explorer For Neovim Written In Lua

Notice

• I am working on this plugin to learn lua, neovim's api and create a file explorer with features i need.
• This plugin does not work on windows.

Install

Install with vim-plug:

Plug 'kyazdani42/nvim-tree.lua'

Setup

let g:lua_tree_side = 'right' | 'left' "left by default
let g:lua_tree_size = 40 "30 by default
let g:lua_tree_ignore = [ '.git', 'node_modules', '.cache' ] "empty by default, not working on mac atm
let g:lua_tree_auto_open = 1 "0 by default, opens the tree when typing `vim $DIR` or `vim`
let g:lua_tree_auto_close = 1 "0 by default, closes the tree when it's the last window
let g:lua_tree_show_folders = 0 "1 by default, do not show folder icons if you font doesn't render them
let g:lua_tree_show_git_icons = 0 "1 by default, do not show git icons if you font doesn't render them
let g:lua_tree_follow = 1 "0 by default, this option will bind BufEnter to the LuaTreeFindFile command
" :help LuaTreeFindFile for more info

nnoremap <C-n> :LuaTreeToggle<CR>
nnoremap <leader>r :LuaTreeRefresh<CR>
nnoremap <leader>n :LuaTreeFindFile<CR>

KeyBindings

• move around like in any vim buffer
• <CR> on .. will cd in the above directory
• . will cd in the directory under the cursor
• type a to add a file
• type r to rename a file
• type d to delete a file (will prompt for confirmation)
• 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
• type <C-v> will open the file in a vertical split
• type <C-x> will open the file in a horizontal split
• type <C-t> will open the file in a new tab
• Double left click acts like <CR>
• Double right click acts like .

Features

• Open file in current buffer or in split with FzF like bindings (<CR>, <C-v>, <C-x>, <C-t>)
• File icons with vim-devicons
• Syntax highlighting (exa like)
• Change directory with .
• Add / Rename / delete files
• Git integration
• Mouse support

TODO

Perf / Fixes

• Tree creation should be async
• refactor all system call to libuv functions, with better error management
• bufferize leafs of node being closed so when opening again the node, we open every directory that was previously open
• make config module to make it easier to add/modify user options

Features

• sneak like cd command to find a file/directory
• better default colors (use default vim groups)
• create proper highlight groups or add highlight function to give the user ability to setup colors themselves

Window Feature / Fixes

• opening help should open on the bottom
• better window management:
  • check tree buffer/window for change so we can avoid it being resized or moved around or replaced by another file
  • monitor window layout in current tab to open files in the right place

this might be a little hard to implement since window layout events do not exist yet
