 1. INTRODUCTION                                      *nvim-tree-introduction*

Features

    - Automatic updates
    - File type icons
    - Git integration
    - Diagnostics integration: LSP and COC
    - (Live) filtering
    - Cut, copy, paste, rename, delete, create
    - Highly customisable

File Icons

    https://github.com/kyazdani42/nvim-web-devicons is optional and used to display file icons. It requires a patched font: https://www.nerdfonts.com

     should look like an open folder.

    To disable the display of icons see |renderer.icons.show|

Colours

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

Git Integration

    Icon indicates 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

Requirements

    This file explorer requires `neovim >= 0.7.0`

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

Setup should be run in a lua file or in a |lua-heredoc| if using in a vim file.

    -- examples for your init.lua

    -- empty setup using defaults
    require("nvim-tree").setup()

    -- OR setup with some options
    require("nvim-tree").setup({
      sort_by = "case_sensitive",
      view = {
        adaptive_size = true,
        mappings = {
          list = {
            { key = "u", action = "dir_up" },
          },
        },
      },
      renderer = {
        group_empty = true,
      },
      filters = {
        dotfiles = true,
      },
    })

 3. COMMANDS                                              *nvim-tree-commands*

|:NvimTreeOpen|

    opens the tree. Takes an optional path argument.

|:NvimTreeClose|

    closes the tree

|:NvimTreeToggle|

    open or close the tree. Takes an optional path argument.

|:NvimTreeFocus|

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

|:NvimTreeRefresh|

    refresh the tree

|: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|

    close the tree or change the cursor in the tree for the current bufname,
    similar to combination of |:NvimTreeToggle| and |:NvimTreeFindFile|. Takes an
    optional path argument.

|:NvimTreeClipboard|

    Print clipboard content for both cut and copy

|:NvimTreeResize|

    Resize the NvimTree window to the given size. Example: `:NvimTreeResize 50`
    resizes the window to the width of 50. If the size starts with "+" or "-" it
    adds or removes the given value to the current window width.
    Example `:NvimTreeResize -20` removes the value 20 from the current width. And
    `:NvimTreeResize +20` adds the value 20 to the current width.

|:NvimTreeCollapse|

    Collapses the nvim-tree recursively.

|:NvimTreeCollapseKeepBuffers|

    Collapses the nvim-tree recursively, but keep the directories open, which are
    used in an open buffer.


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

You must run setup() function to initialise nvim-tree.

setup() function takes one optional argument: configuration table. If omitted
nvim-tree will be initialised with default configuration.

Subsequent calls to setup will replace the previous configuration.

    *nvim-tree.update_focused_file.ignore_list*
    List of buffer names and filetypes that will not update the root dir

    *nvim-tree.system_open.args*
    The command arguments as a list.
      Type: {string}, Default: `{}`

    *nvim-tree.diagnostics.enable*
    Enable/disable the feature.
      Type: `boolean`, Default: `false`

    *nvim-tree.diagnostics.debounce_delay*
    Idle milliseconds between diagnostic event and update.
      Type: `number`, Default: `50` (ms)

    *nvim-tree.diagnostics.show_on_dirs*
    Show diagnostic icons on parent directories.
      Type: `boolean`, Default: `false`

    *nvim-tree.diagnostics.icons*
    Icons for diagnostic severity.
      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 integration with icons and colors.

    *nvim-tree.git.enable*
    Enable / disable the feature.
      Type: `boolean`, Default: `true`

    *nvim-tree.git.ignore*
    Ignore files based on `.gitignore`. Requires |git.enable| `= true`
    Toggle via the `toggle_git_ignored` action, default mapping `I`.
      Type: `boolean`, Default: `true`

    *nvim-tree.git.show_on_dirs*
    Show status icons of children when directory itself has no status icon.
      Type: `boolean`, Default: `true`

    *nvim-tree.git.timeout*
    Kills the git process after some time if it takes too long.
      Type: `number`, Default: `400` (ms)

  You will still need to set |renderer.icons.show.git| `= true` or
  |renderer.highlight_git| `= true` 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.

*nvim-tree.filesystem_watchers*
Will use file system watcher (libuv fs_event) to watch the filesystem for
changes.
Using this will disable BufEnter / BufWritePost events in nvim-tree which
were used to update the whole tree. With this feature, the tree will be
updated only for the appropriate folder change, resulting in better
performance.

    *nvim-tree.filesystem_watchers.enable*
    Enable / disable the feature.
      Type: `boolean`, Default: `true`

    *nvim-tree.filesystem_watchers.debounce_delay*
    Idle milliseconds between filesystem change and action.
      Type: `number`, Default: `50` (ms)

*nvim-tree.on_attach*
Function ran when creating the nvim-tree buffer.
This can be used to attach keybindings to the tree buffer.
When on_attach is "disabled", it will use the older mapping strategy, otherwise it
will use the newer one.
>
    on_attach = function(bufnr)
        local inject_node = require("nvim-tree.utils").inject_node

        vim.keymap.set("n", "<leader>n", inject_node(function(node)
            if node then
                print(node.absolute_path)
            end
        end), { buffer = bufnr, noremap = true })

        vim.bo[bufnr].path = "/tmp"
    end
<
    Type: `function(bufnr)`, Default: `"disable"`

*nvim-tree.remove_keymaps*
This can be used to remove the default mappings in the tree.
- Remove specific keys by passing a `string` table of keys
    eg. {"<C-o>", "<CR>", "o", "<Tab>"}
- Remove all default mappings by passing `true`
- Ignore by passing `false`
    Type: `bool` or `{string}`, Default: `false`

*nvim-tree.view*
Window / buffer setup.

    *nvim-tree.view.adaptive_size*
    Resize the window on each draw based on the longest line.
    Only works when |nvim-tree.view.side| is `left` or `right`.

 4.1 VINEGAR STYLE                                         *nvim-tree-vinegar*

|nvim_tree_vinegar|                                    *nvim_tree_vinegar*

nvim-tree can behave like vinegar. To allow this, you will need to configure
it in a specific way:

- Use `require"nvim-tree".open_replacing_current_buffer()` instead of the
default open command.
You can easily implement a toggle using this too:
>
    local function toggle_replace()
      local view = require"nvim-tree.view"
      if view.is_visible() then
        view.close()
      else
        require"nvim-tree".open_replacing_current_buffer()
      end
    end
<
- Use the `edit_in_place` action to edit files. It's bound to `<C-e>` by
default, vinegar uses `<CR>`. You can override this with:
>
    require"nvim-tree".setup {
      view = {
        mappings = {
          list = {
            { key = "<CR>", action = "edit_in_place" }
          }
        }
      }
    }
<
Going up a dir is bound to `-` by default in nvim-tree which is identical to
vinegar, no change is needed here.

You'll also need to set |nvim-tree.hijack_netrw| to `true` during setup.
A good functionality to enable is |nvim-tree.hijack_directories|.

 5. API                                                   *nvim-tree-api*

This module exposes stable functionalities, it is advised to use this in order
to avoid breaking configurations due to internal breaking changes.

The api is separated in multiple modules, which can be accessed with
`require("nvim-tree.api").moduleName.functionality`.

Functions that needs a tree node parameter are exposed with an abstraction
that injects the node from the cursor position in the tree when calling 
the function. It will use the node you pass as an argument in priority if it
exists.

 6. MAPPINGS                                              *nvim-tree-mappings*

Setting your own mapping in the configuration will soon be deprecated, see |nvim-tree.on_attach| for experimental replacement.

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

- `key` can be either a string or a table of string (lhs)
- `action` is the name of the action, set to `""` to remove default action
- `action_cb` is the function that will be called, it receives the node as a parameter. Optional for default actions
- `mode` is normal by default

 7. HIGHLIGHT GROUPS                                     *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.

Default linked group follows name.

NvimTreeSymlink
NvimTreeFolderName          (Directory)
NvimTreeRootFolder
NvimTreeFolderIcon
NvimTreeFileIcon
NvimTreeEmptyFolderName     (Directory)
NvimTreeOpenedFolderName    (Directory)
NvimTreeExecFile
NvimTreeOpenedFile
NvimTreeSpecialFile
NvimTreeImageFile
NvimTreeIndentMarker

NvimTreeLspDiagnosticsError         (DiagnosticError)
NvimTreeLspDiagnosticsWarning       (DiagnosticWarn)
NvimTreeLspDiagnosticsInformation   (DiagnosticInfo)
NvimTreeLspDiagnosticsHint          (DiagnosticHint)

NvimTreeGitDirty
NvimTreeGitStaged
NvimTreeGitMerge
NvimTreeGitRenamed
NvimTreeGitNew

There are also links to normal bindings to style the tree itself.

NvimTreeNormal
NvimTreeEndOfBuffer     (NonText)
NvimTreeCursorLine      (CursorLine)
NvimTreeVertSplit       (VertSplit)     [deprecated, use NvimTreeWinSeparator]
NvimTreeWinSeparator    (VertSplit)
NvimTreeCursorColumn    (CursorColumn)

There are also links for file highlight with git properties, linked to their
Git equivalent:

NvimTreeFileDirty       (NvimTreeGitDirty)
NvimTreeFileStaged      (NvimTreeGitStaged)
NvimTreeFileMerge       (NvimTreeGitMerge)
NvimTreeFileRenamed     (NvimTreeGitRenamed)
NvimTreeFileNew         (NvimTreeGitNew)
NvimTreeFileDeleted     (NvimTreeGitDeleted)
NvimTreeFileIgnored     (NvimTreeGitIgnored)

There are 2 highlight groups for the live filter feature

 8. 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|

Handlers are registered by calling the `events.subscribe` function available in the
`require("nvim-tree.api")` module.

For example, registering a handler for when a node is renamed is done like this:
>
    local api = require('nvim-tree.api')

    api.events.subscribe(Event.NodeRenamed, function(data)
        print("Node renamed from " .. data.old_name .. " to " ..  data.new_name)
    end)
<

|nvim_tree_events_kind|

You can access the event enum with:
>
    local Event = require('nvim-tree.api').events.Event
<
Here is the list of available variant of this enum:

- Event.Ready 
                When NvimTree has been initialized
                • Note: Handler takes no parameter.

- Event.TreeOpen
                • Note: Handler takes no parameter.

- Event.TreeClose
                • Note: Handler takes no parameter.

- Event.Resize - When NvimTree is resized.
                handler parameters: ~
                    size:        `number` size of the view in columns.

- Event.NodeRenamed
                • Note: A node can either be a file or a directory.
                handler parameters: ~
                  {old_name}     `{string}` Absolute path to the old node location.
                  {new_name}     `{string}` Absolute path to the new node location.

- Event.FileCreated
                handler parameters: ~
                  {fname}        `{string}` Absolute path to the created file

- Event.FileRemoved
                handler parameters: ~
                  {fname}        `{string}` Absolute path to the removed file.

- Event.FolderCreated
                handler parameters: ~
                  {folder_name}  `{string}` Absolute path to the created folder.

- Event.FolderRemoved
                handler parameters: ~
                  {folder_name}  `{string}` Absolute path to the removed folder.

==============================================================================
 9. BOOKMARKS                                      *nvim-tree-bookmarks*

You can toggle marks on files/folders with
`require("nvim-tree.api").marks.toggle(node)` which is bound to `m` by
default.

To get the list of marked paths, you can call
`require("nvim-tree.api").marks.list()`. This will return `{node}`.

*nvim-tree.bookmarks.navigation*

Navigation for marks is not bound by default in nvim-tree because we don't
want to focus the tree view each time we wish to switch to another mark.

This requires binding bookmark navigation yourself.

-- in your lua configuration
vim.keymap.set("n", "<leader>mn", require("nvim-tree.api").marks.navigate.next)
vim.keymap.set("n", "<leader>mp", require("nvim-tree.api").marks.navigate.prev)
vim.keymap.set("n", "<leader>ms", require("nvim-tree.api").marks.navigate.select)
