cder.nvim

A telescope.nvim extension for quickly changing your working directory.

Dependencies

• telescope.nvim
• By default, the extension uses fd to list directories and bat to provide paging. You don't have to use these if you don't want to, but the default config will not work if you do not install them.
• Additionally, bash is used to pipe the output of fd into bat, so if bash is not installed, the command_executor option will need to be changed.

Setup

Install using your favorite plugin manager:

packer.nvim:

use 'zane-/cder.nvim'

Load the extension into telescope:

require('telescope').load_extension('cder')

Default config:

-- The title of the prompt.
prompt_title = function()
    return 'cwd: ' .. vim.fn.getcwd()
end,

-- The command used to generate a list of directories.
-- Defaults to fd on the home directory.
-- Example for showing hidden directories:
--   dir_command = { 'fd', '--hidden', '--type=d', '.', os.getenv('HOME') },
-- Example for excluding certain directories:
--   dir_command = { 'fd', '--exclude=Library', '--exclude=Pictures', '--type=d', '.', os.getenv('HOME') },  
dir_command = { 'fd', '--type=d', '.', os.getenv('HOME') },

-- The binary used to execute previewer_command | pager_command.
-- This is needed because termopen in Neovim does not support piping
-- multiple commands, so we get around this by just using bash -c.
command_executer = { 'bash', '-c' },

-- The command used to preview directories. Defaults to ls.
-- Example:
--   previewer_command = 'exa -a --icons'
previewer_command = 'ls -a',

-- A function to return an entry given an entry produced 
-- by dir_command. Returns the entry directly by default.
entry_value_fn = function(entry_value)
  return '"' .. entry_value .. '"'
end,

-- The command used to page directory previews. Defaults to bat.
-- Receives the output of the previewer_command as input.
-- Example without bat:
--   pager_command = 'less -RS'
pager_command = 'bat --plain --paging=always --pager="less -RS"',

-- Function to create an entry in the picker given
-- a line outputted from the dir_command.
--   value is used as the directory in the :cd command
--   display is what is actually displayed, so this can
--     be a function that trims a path prefix for example.
entry_maker = function(line)
  return {
    value = line,
    display = function(entry)
      return ' ' .. line:gsub(os.getenv('HOME') .. '/', ''), { { { 1, 3 }, 'Directory' } }
    end,
    ordinal = line,
  }
end,

-- A mapping should be a function that takes as parameter the selected
-- directory as a string.
mappings = {
  default = function(directory)
    vim.cmd.cd(directory)
  end,
  ['<C-t>'] = function(directory)
    vim.cmd.tcd(directory)
  end,
},

To change these, use telescope's setup function. Below is the config used in the demo gif above:

require('telescope').setup({
  extensions = {
    cder = {
      previewer_command =
        'exa '..
        '-a '..
        '--color=always '..
        '-T '..
        '--level=3 '..
        '--icons '..
        '--git-ignore '..
        '--long '..
        '--no-permissions '..
        '--no-user '..
        '--no-filesize '..
        '--git '..
        '--ignore-glob=.git',
    },
  },
})

Usage

• Open the extension with :Telescope cder
• Search for a directory name, pressing enter on the selection will change Neovim's working directory
