nvim-telescope/telescope.nvim: Find, Filter, Preview, Pick. All lua, all the time.

Gaze deeply into unknown regions using the power of the moon.

telescope.nvim is a highly extendable fuzzy finder over lists. Built on the latest awesome features from neovim core. Telescope is centered around modularity, allowing for easy customization.

Community driven builtin pickers, sorters and previewers.

This section should guide you to run your first builtin pickers.

Neovim (v0.9.0) or the latest neovim nightly commit is required for telescope.nvim to work. The neovim version also needs to be compiled with LuaJIT, we currently do not support Lua5.1 because of some ongoing issues.

• nvim-lua/plenary.nvim is required.

• BurntSushi/ripgrep is required for live_grep and grep_string and is the first priority for find_files.

We also suggest you install one native telescope sorter to significantly improve sorting performance. Take a look at either telescope-fzf-native.nvim or telescope-fzy-native.nvim. For more information and a performance benchmark take a look at the Extensions wiki.

It is suggested to either use the latest release tag or our release branch (which will get consistent updates) 0.1.x.

It is not suggested to run latest master.

Using vim-plug

Plug 'nvim-lua/plenary.nvim'
Plug 'nvim-telescope/telescope.nvim', { 'tag': '0.1.8' }
" or                                , { 'branch': '0.1.x' }

Using dein

call dein#add('nvim-lua/plenary.nvim')
call dein#add('nvim-telescope/telescope.nvim', { 'rev': '0.1.8' })
" or                                         , { 'rev': '0.1.x' })

Using packer.nvim

use {
  'nvim-telescope/telescope.nvim', tag = '0.1.8',
-- or                            , branch = '0.1.x',
  requires = { {'nvim-lua/plenary.nvim'} }
}

Using lazy.nvim

-- init.lua:
    {
    'nvim-telescope/telescope.nvim', tag = '0.1.8',
-- or                              , branch = '0.1.x',
      dependencies = { 'nvim-lua/plenary.nvim' }

      dependencies = { 'nvim-lua/plenary.nvim' }
    }

Make sure you call :checkhealth telescope after installing telescope to ensure everything is set up correctly.

After this setup you can continue reading here or switch to :help telescope to get an understanding of how to use Telescope and how to configure it.

Try the command :Telescope find_files to see if telescope.nvim is installed correctly.

Using VimL:

" Find files using Telescope command-line sugar.
nnoremap <leader>ff <cmd>Telescope find_files<cr>
nnoremap <leader>fg <cmd>Telescope live_grep<cr>
nnoremap <leader>fb <cmd>Telescope buffers<cr>
nnoremap <leader>fh <cmd>Telescope help_tags<cr>

" Using Lua functions
nnoremap <leader>ff <cmd>lua require('telescope.builtin').find_files()<cr>
nnoremap <leader>fg <cmd>lua require('telescope.builtin').live_grep()<cr>
nnoremap <leader>fb <cmd>lua require('telescope.builtin').buffers()<cr>
nnoremap <leader>fh <cmd>lua require('telescope.builtin').help_tags()<cr>

Using Lua:

local builtin = require('telescope.builtin')
vim.keymap.set('n', '<leader>ff', builtin.find_files, { desc = 'Telescope find files' })
vim.keymap.set('n', '<leader>fg', builtin.live_grep, { desc = 'Telescope live grep' })
vim.keymap.set('n', '<leader>fb', builtin.buffers, { desc = 'Telescope buffers' })
vim.keymap.set('n', '<leader>fh', builtin.help_tags, { desc = 'Telescope help tags' })

See builtin pickers for a list of all builtin functions.

This section should help you explore available options to configure and customize your telescope.nvim.

Unlike most vim plugins, telescope.nvim can be customized by either applying customizations globally, or individually per picker.

• Global Customization affecting all pickers can be done through the main setup() method (see defaults below)
• Individual Customization affecting a single picker by passing opts to builtin pickers (e.g. builtin.find_files(opts)) see Configuration recipes wiki page for ideas.

require('telescope').setup{
  defaults = {
    -- Default configuration for telescope goes here:
    -- config_key = value,
    mappings = {
      i = {
        -- map actions.which_key to <C-h> (default: <C-/>)
        -- actions.which_key shows the mappings for your picker,
        -- e.g. git_{create, delete, ...}_branch for the git_branches picker
        ["<C-h>"] = "which_key"
      }
    }
  },
  pickers = {
    -- Default configuration for builtin pickers goes here:
    -- picker_name = {
    --   picker_config_key = value,
    --   ...
    -- }
    -- Now the picker_config_key will be applied every time you call this
    -- builtin picker
  },
  extensions = {
    -- Your extension configuration goes here:
    -- extension_name = {
    --   extension_config_key = value,
    -- }
    -- please take a look at the readme of the extension you want to configure
  }
}

To look at what default configuration options exist please read: :help telescope.setup(). For picker specific opts please read: :help telescope.builtin.

To embed the above code snippet in a .vim file (for example in after/plugin/telescope.nvim.vim), wrap it in lua << EOF code-snippet EOF:

lua << EOF
require('telescope').setup{
  -- ...
}
EOF

Mappings are fully customizable. Many familiar mapping patterns are set up as defaults.

To see the full list of mappings, check out lua/telescope/mappings.lua and the default_mappings table.

Tip: you can use <C-/> and ? in insert and normal mode, respectively, to show the actions mapped to your picker.

Much like builtin pickers, there are a number of actions you can pick from to remap your telescope buffer mappings, or create a new custom action:

-- Built-in actions
local transform_mod = require('telescope.actions.mt').transform_mod

-- or create your custom action
local my_cool_custom_action = transform_mod({
  x = function(prompt_bufnr)
    print("This function ran after another action. Prompt_bufnr: " .. prompt_bufnr)
    -- Enter your function logic here. You can take inspiration from lua/telescope/actions.lua
  end,
})

To remap telescope mappings, please read :help telescope.defaults.mappings. To do picker specific mappings, its suggested to do this with the pickers table in telescope.setup. Each picker accepts a mappings table like its explained in :help telescope.defaults.mappings.

Built-in functions. Ready to be bound to any key you like.

:lua require'telescope.builtin'.planets{}

:nnoremap <Leader>pp :lua require'telescope.builtin'.planets{}

The default previewers are from now on vim_buffer_ previewers. They use vim buffers for displaying files and use tree-sitter or regex for file highlighting.

These previewers are using vim.filetype to guess the filetype for the selected file. The guessing is done by inspecting the filename, the head of the file(shebang) and the tail of the file (modeline). If you have trouble with filetype detection you should read :help vim.filetype.

We need to do it manually because we can't determine the filetype in the traditional way: We don't do bufload and instead read the file asynchronously with vim.loop.fs_ and attach only a highlighter; otherwise the speed of the previewer would slow down considerably.

If you want to configure the vim_buffer_ previewer (e.g. you want the line to wrap), do this:

vim.api.nvim_create_autocmd("User", {
  pattern = "TelescopePreviewerLoaded",
  callback = function(args)
    if args.data.filetype ~= "help" then
      vim.wo.number = true
    elseif args.data.bufname:match("*.csv") then
      vim.wo.wrap = false
    end
  end,
})

A data field is passed to the callback, which contains the filetype and the buffer name.

{
  title: string, # preview window title
  filetype: string,
  bufname: string,
}

A Sorter is called by the Picker on each item returned by the Finder. It returns a number, which is equivalent to the "distance" between the current prompt and the entry returned by a finder.

Layout can be configured by choosing a specific layout_strategy and specifying a particular layout_config for that strategy. For more details on available strategies and configuration options, see :help telescope.layout.

Some options for configuring sizes in layouts are "resolvable". This means that they can take different forms, and will be interpreted differently according to which form they take. For example, if we wanted to set the width of a picker using the vertical layout strategy to 50% of the screen width, we would specify that width as 0.5, but if we wanted to specify the width to be exactly 80 characters wide, we would specify it as 80. For more details on resolving sizes, see :help telescope.resolve.

As an example, if we wanted to specify the layout strategy and width, but only for this instance, we could do something like:

:lua require('telescope.builtin').find_files({layout_strategy='vertical',layout_config={width=0.5}})

If we wanted to change the width for every time we use the vertical layout strategy, we could add the following to our setup() call:

require('telescope').setup({
  defaults = {
    layout_config = {
      vertical = { width = 0.5 }
      -- other layout configuration here
    },
    -- other defaults configuration here
  },
  -- other configuration values here
})

Common groups of settings can be set up to allow for themes. We have some built in themes but are looking for more cool options.

To use a theme, simply append it to a builtin function:

nnoremap <Leader>f :lua require'telescope.builtin'.find_files(require('telescope.themes').get_dropdown({}))<cr>
" Change an option
nnoremap <Leader>f :lua require'telescope.builtin'.find_files(require('telescope.themes').get_dropdown({ winblend = 10 }))<cr>

Or use with a command:

Telescope find_files theme=dropdown

Or you can configure it in the pickers table in telescope.setup:

require('telescope').setup{
  defaults = {
    -- ...
  },
  pickers = {
    find_files = {
      theme = "dropdown",
    }
  },
  extensions = {
    -- ...
  }
}

Themes should work with every telescope.builtin function. If you wish to make a theme, check out lua/telescope/themes.lua.

All telescope.nvim functions are wrapped in vim commands for easy access, tab completions and setting options.

" Show all builtin pickers
:Telescope

" Tab completion
:Telescope |<tab>
:Telescope find_files

" Setting options
:Telescope find_files prompt_prefix=🔍

" If the option accepts a Lua table as its value, you can use, to connect each
" command string, e.g.: find_command, vimgrep_arguments are both options that
" accept a Lua table as a value. So, you can configure them on the command line
"like so:
:Telescope find_files find_command=rg,--ignore,--hidden,--files prompt_prefix=🔍

for more information and how to realize more complex commands please read :help telescope.command.

Telescope user autocmds:

Telescope provides the capabilities to create & register extensions, which improves telescope in a variety of ways.

Some extensions provide integration with external tools, outside of the scope of builtins. Others provide performance enhancements by using compiled C and interfacing directly with Lua over LuaJIT's FFI library.

A list of community extensions can be found in the Extensions wiki. Always read the README of the extension you want to install, but here is a general overview of how most extensions work.

To load an extension, use the load_extension function as shown in the example below:

-- This will load fzy_native and have it override the default file sorter
require('telescope').load_extension('fzy_native')

You may skip explicitly loading extensions (they will then be lazy-loaded), but tab completions will not be available right away.

Pickers from extensions are added to the :Telescope command under their respective name. For example:

" Run the `configurations` picker from nvim-dap
:Telescope dap configurations

They can also be called directly from Lua:

-- Run the `configurations` picker from nvim-dap
require('telescope').extensions.dap.configurations()

For writing your own picker and for information about the API please read the Developers Documentation.
