KeyBindings

  • move around like in any vim buffer
  • <CR> on.. will cd in the above directory
  • <C-]> will cd in the directory under the cursor
  • typea 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

  • typer to rename a file
  • typex to add/remove file/directory to cut clipboard
  • typec to add/remove file/directory to copy clipboard
  • typep to paste from clipboard. Cut clipboard has precedence over copy (will prompt for confirmation)
  • typed to delete a file (will prompt for confirmation)
  • type]c to go to next git item
  • type[c to go to prev git item
  • 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:lua_tree_ignore|
  • H will toggle visibility of dotfiles (files/folders starting with a.)
  • R will refresh the tree
  • gx opens the file with theopen command on MACOS andxdg-open in linux
  • Double left click acts like<CR>
  • Double right click acts like<C-]>

Note

This plugin is very fast because it uses thelibuvscandir andscandir_next functions instead of spawning anls process which can get slow on large files when combining withstat to get file informations.

The Netrw vim plugin is disabled, hence features likegx don't work across your windows/buffers. You could use a plugin likethis one if you wish to use that feature.

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
