KeyBindings

Default actions

• move around like in any vim buffer
• <CR> or o on .. will cd in the above directory
• <C-]> will cd in the directory under the cursor
• <BS> will close current opened directory or parent
• 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 <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 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
• type '-' to naviate up to the parent directory of the 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
• 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:nvim_tree_ignore|
• H will toggle visibility of dotfiles (files/folders starting with a .)
• R will refresh the tree
• Double left click acts like <CR>
• Double right click acts like <C-]>

Setup

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"),
      ["<BS>"]           = tree_cb("close_node"),
      ["<S-CR>"]         = tree_cb("close_node"),
      ["<Tab>"]          = tree_cb("preview"),
      ["I"]              = tree_cb("toggle_ignored"),
      ["H"]              = tree_cb("toggle_dotfiles"),
      ["R"]              = tree_cb("refresh"),
      ["a"]              = tree_cb("create"),
      ["d"]              = tree_cb("remove"),
      ["r"]              = tree_cb("rename"),
      ["<C-r>"]          = tree_cb("full_rename"),
      ["x"]              = tree_cb("cut"),
      ["c"]              = tree_cb("copy"),
      ["p"]              = tree_cb("paste"),
      ["[c"]             = tree_cb("prev_git_item"),
      ["]c"]             = tree_cb("next_git_item"),
      ["-"]              = tree_cb("dir_up"),
      ["q"]              = tree_cb("close"),
    }
EOF

All mappings are set in normal mode.

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.

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
