This file explorer requires neovim `nightly (>= 0.5.0)`

==============================================================================
QUICK START                                        *nvim-tree-quickstart*

open the tree with :NvimTreeToggle
>
  nnoremap <C-n> :NvimTreeToggle<CR>
  lua require 'nvim-tree'.toggle()
<

==============================================================================
COMMANDS                                           *nvim-tree-commands*

|:NvimTreeOpen| 	                                  *:NvimTreeOpen*

opens the tree

|:NvimTreeClose| 	                          *:NvimTreeClose*

refresh the tree

|:NvimTreeFindFile|				  *:NvimTreeFindFile*

The command will change the cursor in the tree for the current bufname.

It will also open the leafs of the tree leading to the file in the buffer
(if you opened a file with something else than the NvimTree, like `fzf` or
`:split`)

|:NvimTreeClipboard|			          *:NvimTreeClipboard*

Print clipboard content for both cut and copy

==============================================================================
OPTIONS				                  *nvim-tree-options*

|g:nvim_tree_width|				*g:nvim_tree_width*

width of the window (default to 30)

|g:nvim_tree_side|				*g:nvim_tree_side*

where the window will open (default to 'left')
- 'left' or 'right'

|g:nvim_tree_ignore|				*g:nvim_tree_ignore*

An array of strings that the tree won't load and display.
useful to hide large data/cache folders.
>
    example: let g:nvim_tree_ignore = [ '.git', 'node_modules' ]

|g:nvim_tree_gitignore|				*g:nvim_tree_gitignore*

Determines whether to include in g:nvim_tree_ignore
files ignored by git.

Must be:
    0: not ignored
    1: ignored files from `git ls-files --others --ignored --exclude-standard --directory`

>
|g:nvim_tree_show_icons|			        *g:nvim_tree_show_icons*

Dictionary, if your terminal or font doesn't support certain unicode
character, the tree UI might be messed up. The following configuration
can disable icons per type:
>
    let g:nvim_tree_show_icons = {
	\ 'git': 1,
	\ 'folders': 1,
	\ 'icons': 1
	\}

Can be one of `1` and `0` for each key. By default the tree will try
to render the icons. The `icons` key can only work if `nvim-web-devicons`
is installed and in your |runtimepath|
(https://github.com/kyazdani42/nvim-web-devicons)

|g:nvim_tree_highlight_opened_files|			        *g:nvim_tree_highlight_opened_files*

Can be `0` or `1`. When `1`, will highlight icons for opened files and directories
Default is 0

|g:nvim_tree_icons|                                *g:nvim_tree_icons*

You can set icons for:

- The git status.
- The default icon that shows when no icon is found for a file
  or if you are not using icons.
- Symlinks. If an icon is not provided, the `default` icon is used.

INFORMATIONS				        *nvim-tree-info*

|KeyBindings|				        *nvim-tree-keybindings*

- move around like in any vim buffer
- '<CR>' on '..' will cd in the above directory
- typing '<C-]>' will cd in the directory under the cursor
- typing '<BS>' will close current opened directory or parent
- typing 'P' will move cursor to the parent directory

- type 'a' to add 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 'p' to paste from clipboard. Cut clipboard has precedence over copy
  (will prompt for confirmation)

- type ']c' to go to next git item
- type '[c' to go to prev git item
- type '-' to navigate up one directory

- type 'J' to navigate to the first sibling of current file/directory
- type 'K' to navigate to the last sibling of current file/directory

- if the file is a directory, '<CR>' will open the directory
- otherwise it will open the file in the buffer near the tree

- Double left click acts like '<CR>'
- Double right click acts like '<C-]>'

|g:nvim_tree_bindings|                             *g:nvim_tree_bindings*

You can disable default mappings with
>
    let nvim_tree_disable_keybindings=1
<
But you won't be able to map any keys from the setup with nvim_tree_bindings. Use with caution.

Default keybindings can be overriden. You can also define your own keymappings for the tree view:
>
    lua <<EOF
	local tree_cb = require'nvim-tree.config'.nvim_tree_callback
	vim.g.nvim_tree_bindings = {
	  ["<CR>"] = ":YourVimFunction()<cr>",
	  ["u"] = ":lua require'some_module'.some_function()<cr>",

	  -- default mappings
	  ["<CR>"]           = tree_cb("edit"),
	  ["o"]              = tree_cb("edit"),
	  ["<2-LeftMouse>"]  = tree_cb("edit"),
	  ["<2-RightMouse>"] = tree_cb("cd"),
	  ["<C-]>"]          = tree_cb("cd"),
	  ["<C-v>"]          = tree_cb("vsplit"),
	  ["<C-x>"]          = tree_cb("split"),
	  ["<C-t>"]          = tree_cb("tabnew"),
	  ["<"]              = tree_cb("prev_sibling"),

	  ["P"]              = tree_cb("parent_node"),
	  ["<BS>"]           = tree_cb("close_node"),
	  ["<S-CR>"]         = tree_cb("close_node"),

	}
    EOF

All mappings are set in `normal mode`.

|Features|					*nvim-tree-features*

File icons with vim-devicons.

Uses other type of icons so a good font support is recommended.
If the tree renders weird glyphs, install the correct fonts.

Syntax highlighting uses g:terminal_color_ from colorschemes, fallbacks to
ugly colors otherwise.

Git integration tells when a file is:
- ✗  unstaged or folder is dirty
- ✓  staged
- ★  new file
- ✓ ✗ partially staged
- ✓ ★ new file staged
- ✓ ★ ✗ new file staged and has unstaged modifications
- ═  merging
- ➜  renamed

Mouse support defined in |KeyBindings|

You should have 'termguicolors' enabled, otherwise, colors will not be
applied.

EVENTS                                                 *nvim-tree-events*

|nvim_tree_events|                                     *nvim_tree_events*

nvim-tree will dispatch events whenever an action is made. These events can be
subscribed to through handler functions. This allows for even further
customization of nvim-tree.

A handler for an event is just a function which receives one argument -
the payload of the event. The payload is different for each event type. Refer
to |nvim_tree_registering_handlers| for more information.
<

|nvim_tree_registering_handlers|                *nvim_tree_registering_handlers*

Handlers are registered by calling the `on_*` functions available in the
`require('nvim-tree.events')` module. See |nvim-tree.events|.


For example, registering a handler for when a node is renamed is done like this: >

    local events = require('nvim-tree.events')

    events.on_node_renamed(function(data)
        print("Node renamed from " .. data.old_name .. " to " ..  data.new_name)
    end)
