==============================================================================
INTRODUCTION                                       *nvim-tree-introduction*

This file explorer requires `neovim >= 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*

closes the tree

|:NvimTreeToggle| 	                          *:NvimTreeToggle*

open or close the tree

|:NvimTreeFocus| 	                          *:NvimTreeFocus*

open the tree if it is closed, and then focus on the tree

|:NvimTreeRefresh|			          *:NvimTreeRefresh*

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`)

|:NvimTreeFindFileToggle|			  *:NvimTreeFindFileToggle*

close the tree or change the cursor in the tree for the current bufname,
similar to combination of |:NvimTreeToggle| and |:NvimTreeFindFile|

|:NvimTreeClipboard|			          *:NvimTreeClipboard*

Print clipboard content for both cut and copy

|:NvimTreeResize|			          *:NvimTreeResize*

Resize the NvimTree window to the given size. Example: `:NvimTreeresize 50`
resizes the window to the width of 50.

==============================================================================
SETUP                                *nvim-tree.setup*

To configure the tree (and make it runnable), you should call the setup
function.

  the tree.
  type: `boolean`
  default: `false`

*nvim-tree.update_focused_file*
- |update_focused_file|: update the focused file on `BufEnter`, un-collapses
  the folders recursively until it finds the file

  - |update_focused_file.enable|: enable this feature.
    type: `boolean`
    default: `false`

  - |update_focused_file.update_cwd|: update the root directory of the tree to the one
    of the folder containing the file if the file is not under the current root
    directory. Only relevant when |update_focused_file.enable| is `true`
    type: `boolean`
    default: `false`

  - |update_focused_file.ignore_list|: list of buffer names and filetypes that will not
    update the root dir of the tree if the file isn't found under the current root
    directory. Only relevant when |update_focused_file.update_cwd| is `true` and
    |update_focused_file.enable| is `true`.

    default: `{}`

*nvim-tree.system_open*
- |system_open|: configuration options for the system open command

    useful if you want to override the default command with another one.
    type: `string`
    default: `nil`

  - |system_open.args|: the command arguments as a list
    type: `{string}`
    default: `{}`

- |diagnostics|: show lsp diagnostics in the signcolumn

  - |diagnostics.enable|: enable/disable the feature
      type: `boolean`
      default: `false`

    then show diagnostic in the parent directory
      type: `boolean`
      default: `false`

      type: `table`
      default: `{ hint = "", info = "", warning = "", error = "" }`

    `NOTE`: it will use the default diagnostic color groups to highlight the signs.
    If you wish to customize, you can override these groups:
    - `NvimTreeLspDiagnosticsError`
    - `NvimTreeLspDiagnosticsWarning`
    - `NvimTreeLspDiagnosticsInformation`
    - `NvimTreeLspDiagnosticsHint`

*nvim-tree.git*
- |git|: git integration with icons and colors

  - |git.enable|: enable / disable the feature
    type: `boolean`
    default: `true`

  - |git.ignore|: ignore files based on `.gitignore`.
    will add `ignored=matching` to the integration when `true`. Otherwise will
    add `ignored=no` to the integration which can lead to better performance.

  - |git.timeout|: kills the git process after some time if it takes too long
    type: `number`
    default: `400` (ms)

  You will still need to configure `g:nvim_tree_show_icons.git` or
  `g:nvim_tree_git_hl` to be able to see things in the tree. This will be
  changed in the future versions.

  The configurable timeout will kill the current process and so disable the
  git integration for the project that takes too long.
  The git integration is blocking, so if your timeout is too long (like not in
  milliseconds but a few seconds), it will not render anything until the git
  process returned the data.

      type: `string`
      default: 'left'

  - |view.auto_resize|: auto resize the tree after opening a file
      type: `boolean`
      default: false

  - |view.number|: print the line number in front of each line.
      type: `boolean`
      default: false

  - |view.relativenumber|: show the line number relative to the line with the
    cursor in front of each line. If the option `view.number` is also `true`,
    the number on the cursor line will be the line number instead of `0`.
      type: `boolean`
      default: false

  - |view.signcolumn|: show diagnostic sign column. Value can be `"yes"`,
    `"auto"`, `"no"`

      type: `string`
      default: `"trash"`

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

|g:nvim_tree_width|				*g:nvim_tree_width*

width of the window, can be *width_in_columns* or *'width_in_percent%'*
>
    let g:nvim_tree_width = 30 " indicates width of 30 columns
    let g:nvim_tree_width = '30%' " indicates width of 30% of '&columns'

|g:nvim_tree_side|				*g:nvim_tree_side*

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

|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,
	\ 'files': 1,
  \ 'folder_arrows': 1,
	\}

Can be one of `1` and `0` for each key. By default the tree will try
to render the icons. The `files` key can only work if `nvim-web-devicons`
is installed and in your |runtimepath|
(https://github.com/kyazdani42/nvim-web-devicons)
if folder is 1, you can also set `folder_arrows = 1` to show small arrows
next to the folder icons but this will not work when you set
|g:nvim_tree_indent_markers| (because of UI conflict).

|g:nvim_tree_highlight_opened_files|			        *g:nvim_tree_highlight_opened_files*

Highlight icons and/or names for opened files and directories
Default is 0

Must be:
    0: No highlight
    1: Enable highligting for folders and file icons only.
    2: Enable highligting for folders and file names only.
    3: Enable highligting for folders and both file icons and names.

|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.

|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|

HIGHLIGHT GROUPS				        *nvim-tree-highlight*

|nvim_tree_highlight|				        *nvim_tree_highlight*

All the following highlight groups can be configured by hand. Aside from
`NvimTreeWindowPicker`, it is not advised to colorize the background of these
groups.

Example (in your `init.vim`):
>
    highlight NvimTreeSymlink guifg=blue gui=bold,underline
<
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)
