*telescope.nvim*
Telescope.nvim is a plugin for fuzzy finding and neovim. It helps you search,
filter, find and pick things in Lua.
Getting started with telescope:
1. Run `:checkhealth telescope` to make sure everything is installed.
2. Evalulate it working with `:Telescope find_files` or `:lua
require("telescope.builtin").find_files()`
3. Put a `require("telescope").setup() call somewhere in your neovim config.
4. Read |telescope.setup| to check what config keys are available and what
you can put inside the setup call
5. Read |telescope.builtin| to check which builtin pickers are offered and
what options these implement
6. Profit
The below flow chart illustrates a simplified telescope architecture:

+ The `Entry Maker` at least defines
- value: "raw" result of the finder
- ordinal: string to be sorted derived from value
- display: line representation of entry in results buffer
* The finder, entry manager, selected entry, and multi selections
comprises `entries` constructed by the `Entry Maker` from
raw results of the finder (`value`s)
Primary components:
1 Picker: central UI dedicated to varying use cases
(finding files, grepping, diagnostics, etc.)
see :h telescope.builtin
2 Finder: pipe or interactively generates results to pick over
3 Prompt: user input that triggers the finder which sorts results
in order into the entry manager
4 Results: listed entries scored by sorter from finder results
5 Previewer: preview of context of selected entry
see :h telescope.previewers
A practical introduction into telescope customization is our `developers.md`
(top-level of repo) and `:h telescope.actions` that showcase how to access
information about the state of the picker (current selection, etc.).

<
Valid keys for {opts.defaults}
*telescope.defaults.sorting_strategy*
sorting_strategy: ~
Determines the direction "better" results are sorted towards.
Available options are:
- "descending" (default)
- "ascending"
*telescope.defaults.tiebreak*
tiebreak: ~
A function that determines how to break a tie when two entries have
the same score.
Having a function that always returns false would keep the entries in
the order they are found, so existing_entry before current_entry.
Vice versa always returning true would place the current_entry
before the existing_entry.
Signature: function(current_entry, existing_entry, prompt) -> boolean
Default: function that breaks the tie based on the length of the
entry's ordinal
*telescope.defaults.selection_strategy*
selection_strategy: ~
Determines how the cursor acts after each sort iteration.
Available options are:
- "reset" (default)
- "follow"
- "row"
- "closest"
*telescope.defaults.scroll_strategy*
scroll_strategy: ~
Determines what happens if you try to scroll past the view of the
picker.
Available options are:
- "cycle" (default)
- "limit"
*telescope.defaults.layout_strategy*
layout_strategy: ~
Determines the default layout of Telescope pickers.
See |telescope.layout| for details of the available strategies.
Default: 'horizontal'
*telescope.defaults.layout_config*
layout_config: ~
Determines the default configuration values for layout strategies.
See |telescope.layout| for details of the configurations options for
each strategy.
Allows setting defaults for all strategies as top level options and
for overriding for specific options.
For example, the default values below set the default width to 80% of
the screen width for all strategies except 'center', which has width
of 50% of the screen width.
Default: {
bottom_pane = {
height = 25,
preview_cutoff = 120,
prompt_position = "top"
},
center = {
height = 0.4,
preview_cutoff = 40,
prompt_position = "top",
width = 0.5
},
cursor = {
height = 0.9,
preview_cutoff = 40,
width = 0.8
},
horizontal = {
height = 0.9,
preview_cutoff = 120,
prompt_position = "bottom",
width = 0.8
},
vertical = {
height = 0.9,
preview_cutoff = 40,
prompt_position = "bottom",
width = 0.8
}
}
*telescope.defaults.cycle_layout_list*
cycle_layout_list: ~
Determines the layouts to cycle through when using `actions.cycle_layout_next`
and `actions.cycle_layout_prev`.
Should be a list of "layout setups".
Each "layout setup" can take one of two forms:
1. string <br>
This is interpreted as the name of a `layout_strategy`
2. table <br>
A table with possible keys `layout_strategy`, `layout_config` and `previewer`
Default: { "horizontal", "vertical" }
*telescope.defaults.winblend*
winblend: ~
Configure winblend for telescope floating windows. See |winblend| for
more information.
Default: 0
*telescope.defaults.wrap_results*
wrap_results: ~
Word wrap the search results
Default: false
*telescope.defaults.prompt_prefix*
prompt_prefix: ~
The character(s) that will be shown in front of Telescope's prompt.
Default: '> '
*telescope.defaults.selection_caret*
selection_caret: ~
The character(s) that will be shown in front of the current selection.
Default: '> '
*telescope.defaults.entry_prefix*
entry_prefix: ~
Prefix in front of each result entry. Current selection not included.
Default: ' '
*telescope.defaults.multi_icon*
multi_icon: ~
Symbol to add in front of a multi-selected result entry.
Replaces final character of |telescope.defaults.selection_caret| and
|telescope.defaults.entry_prefix| as appropriate.
To have no icon, set to the empty string.
Default: '+'
*telescope.defaults.initial_mode*
initial_mode: ~
Determines in which mode telescope starts. Valid Keys:
`insert` and `normal`.
Default: "insert"
*telescope.defaults.border*
border: ~
Boolean defining if borders are added to Telescope windows.
Default: true
*telescope.defaults.path_display*
path_display: ~
Determines how file paths are displayed
path_display can be set to an array with a combination of:
- "hidden" hide file names
- "tail" only display the file name, and not the path
- "absolute" display absolute paths
- "smart" remove as much from the path as possible to only show
the difference between the displayed paths.
Warning: The nature of the algorithm might have a negative
performance impact!
- "shorten" only display the first character of each directory in
the path
- "truncate" truncates the start of the path when the whole path will
not fit. To increase the the gap between the path and the edge.
set truncate to number `truncate = 3`
You can also specify the number of characters of each directory name
to keep by setting `path_display.shorten = num`.
e.g. for a path like
`alpha/beta/gamma/delta.txt`
setting `path_display.shorten = 1` will give a path like:
`a/b/g/delta.txt`
Similarly, `path_display.shorten = 2` will give a path like:
`al/be/ga/delta.txt`
You can also further customise the shortening behaviour by
setting `path_display.shorten = { len = num, exclude = list }`,
where `len` acts as above, and `exclude` is a list of positions
that are not shortened. Negative numbers in the list are considered
relative to the end of the path.
e.g. for a path like
`alpha/beta/gamma/delta.txt`
setting `path_display.shorten = { len = 1, exclude = {1, -1} }`
will give a path like:
`alpha/b/g/delta.txt`
setting `path_display.shorten = { len = 2, exclude = {2, -2} }`
will give a path like:
`al/beta/gamma/de`
path_display can also be set to 'hidden' string to hide file names
path_display can also be set to a function for custom formatting of
the path display. Example:
-- Format path as "file.txt (path\to\file\)"
path_display = function(opts, path)
local tail = require("telescope.utils").path_tail(path)
return string.format("%s (%s)", tail, path)
end,
Default: {}
*telescope.defaults.borderchars*
borderchars: ~
Set the borderchars of telescope floating windows. It has to be a
table of 8 string values.
Default: { "─", "│", "─", "│", "╭", "╮", "╯", "╰" }
*telescope.defaults.get_status_text*
get_status_text: ~
A function that determines what the virtual text looks like.
Signature: function(picker) -> str
Default: function that shows current count / all
*telescope.defaults.hl_result_eol*
hl_result_eol: ~
Changes if the highlight for the selected item in the results
window is always the full width of the window
Default: true
*telescope.defaults.dynamic_preview_title*
dynamic_preview_title: ~
Will change the title of the preview window dynamically, where it
is supported. For example, the preview window's title could show up as
the full filename.
Default: false
*telescope.defaults.results_title*
results_title: ~
Defines the default title of the results window. A false value
can be used to hide the title altogether.
Default: "Results"
*telescope.defaults.prompt_title*
prompt_title: ~
Defines the default title of the prompt window. A false value
can be used to hide the title altogether. Most of the times builtins
define a prompt_title which will be prefered over this default.
Default: "Prompt"
*telescope.defaults.history*
history: ~
This field handles the configuration for prompt history.
By default it is a table, with default values (more below).
To disable history, set it to false.
Currently mappings still need to be added, Example:
mappings = {
i = {
["<C-Down>"] = require('telescope.actions').cycle_history_next,
["<C-Up>"] = require('telescope.actions').cycle_history_prev,
},
},
Fields:
- path: The path to the telescope history as string.
default: stdpath("data")/telescope_history
- limit: The amount of entries that will be written in the
history.
Warning: If limit is set to nil it will grow unbound.
default: 100
- handler: A lua function that implements the history.
This is meant as a developer setting for extensions to
override the history handling, e.g.,
https://github.com/nvim-telescope/telescope-smart-history.nvim,
which allows context sensitive (cwd + picker) history.
Default:
require('telescope.actions.history').get_simple_history
*telescope.defaults.cache_picker*
cache_picker: ~
This field handles the configuration for picker caching.
By default it is a table, with default values (more below).
To disable caching, set it to false.
Caching preserves all previous multi selections and results and
therefore may result in slowdown or increased RAM occupation
if too many pickers (`cache_picker.num_pickers`) or entries
('cache_picker.limit_entries`) are cached.
Fields:
- num_pickers: The number of pickers to be cached.
Set to -1 to preserve all pickers of your session.
If passed to a picker, the cached pickers with
indices larger than `cache_picker.num_pickers` will
be cleared.
Default: 1
- limit_entries: The amount of entries that will be written in the
Default: 1000
*telescope.defaults.preview*
preview: ~
This field handles the global configuration for previewers.
By default it is a table, with default values (more below).
To disable previewing, set it to false. If you have disabled previewers
globally, but want to opt in to previewing for single pickers, you will have to
pass `preview = true` or `preview = {...}` (your config) to the `opts` of
your picker.
Fields:
- check_mime_type: Use `file` if available to try to infer whether the
file to preview is a binary if plenary's
filetype detection fails.
Windows users get `file` from:
https://github.com/julian-r/file-windows
Set to false to attempt to preview any mime type.
Default: true for all OS excl. Windows
- filesize_limit: The maximum file size in MB attempted to be previewed.
Set to false to attempt to preview any file size.
Default: 25
- timeout: Timeout the previewer if the preview did not
complete within `timeout` milliseconds.
Set to false to not timeout preview.
Default: 250
- hook(s): Function(s) that takes `(filepath, bufnr, opts)`, where opts
exposes winid and ft (filetype).
Available hooks (in order of priority):
{filetype, mime, filesize, timeout}_hook
Important: the filetype_hook must return true or false
to indicate whether to continue (true) previewing or not (false),
respectively.
Two examples:
local putils = require("telescope.previewers.utils")
... -- preview is called in telescope.setup { ... }
preview = {
-- 1) Do not show previewer for certain files
filetype_hook = function(filepath, bufnr, opts)
-- you could analogously check opts.ft for filetypes
local excluded = vim.tbl_filter(function(ending)
return filepath:match(ending)
end, {
".*%.csv",
".*%.toml",
})
if not vim.tbl_isempty(excluded) then
putils.set_preview_message(
bufnr,
opts.winid,
string.format("I don't like %s files!",
excluded[1]:sub(5, -1))
)
return false
end
return true
end,
-- 2) Truncate lines to preview window for too large files
filesize_hook = function(filepath, bufnr, opts)
local path = require("plenary.path"):new(filepath)
-- opts exposes winid
local height = vim.api.nvim_win_get_height(opts.winid)
local lines = vim.split(path:head(height), "[\r]?\n")
vim.api.nvim_buf_set_lines(bufnr, 0, -1, false, lines)
end,
}

Note: if plenary does not recognize your filetype yet --
1) Please consider contributing to:
$PLENARY_REPO/data/plenary/filetypes/builtin.lua
2) Register your filetype locally as per link
https://github.com/nvim-lua/plenary.nvim#plenaryfiletype
Default: nil
- treesitter: Determines whether the previewer performs treesitter
highlighting, which falls back to regex-based highlighting.
`true`: treesitter highlighting for all available filetypes
`false`: regex-based highlighting for all filetypes
`table`: table of filetypes for which to attach treesitter
highlighting
Default: true
- msg_bg_fillchar: Character to fill background of unpreviewable buffers with
Default: "╱"
- hide_on_startup: Hide previewer when picker starts. Previewer can be toggled
with actions.toggle_preview.
Default: false
*telescope.defaults.vimgrep_arguments*
vimgrep_arguments: ~
Defines the command that will be used for `live_grep` and `grep_string`
pickers.
Hint: Make sure that color is currently set to `never` because we do
not yet interpret color codes
Hint 2: Make sure that these options are in your changes arguments:
"--no-heading", "--with-filename", "--line-number", "--column"
because we need them so the ripgrep output is in the correct format.
Default: {
"rg",
"--color=never",
"--no-heading",
"--with-filename",
"--line-number",
"--column",
"--smart-case"
}
*telescope.defaults.use_less*
use_less: ~
Boolean if less should be enabled in term_previewer (deprecated and
currently no longer used in the builtin pickers).
Default: true
*telescope.defaults.set_env*
set_env: ~
Set an environment for term_previewer. A table of key values:
Example: { COLORTERM = "truecolor", ... }
Hint: Empty table is not allowed.
Default: nil
*telescope.defaults.color_devicons*
color_devicons: ~
Boolean if devicons should be enabled or not. If set to false, the
"TelescopeResultsFileIcon" highlight group is used.
Hint: Coloring only works if |termguicolors| is enabled.
Default: true
*telescope.defaults.mappings*
mappings: ~
Your mappings to override telescope's default mappings.
Format is:
{
mode = { ..keys }
}
where {mode} is the one character letter for a mode
('i' for insert, 'n' for normal).
For example:
mappings = {
i = {
["<esc>"] = require('telescope.actions').close,
},
}
To disable a keymap, put [map] = false
So, to not map "<C-n>", just put
...,
["<C-n>"] = false,
...,
Into your config.
otherwise, just set the mapping to the function that you want it to
be.
...,
["<C-i>"] = require('telescope.actions').select_default,
...,
If the function you want is part of `telescope.actions`, then you can
simply give a string.
For example, the previous option is equivalent to:
...,
["<C-i>"] = "select_default",
...,
You can also add other mappings using tables with `type = "command"`.
For example:
...,
["jj"] = { "<esc>", type = "command" },
["kk"] = { "<cmd>echo \"Hello, World!\"<cr>", type = "command" },)
...,
You can also add additional options for mappings of any type
("action" and "command"). For example:
...,
["<C-j>"] = {
action = actions.move_selection_next,
opts = { nowait = true, silent = true }
},
...,
*telescope.defaults.default_mappings*
default_mappings: ~
Not recommended to use except for advanced users.
Will allow you to completely remove all of telescope's default maps
and use your own.
*telescope.defaults.file_sorter*
file_sorter: ~
A function pointer that specifies the file_sorter. This sorter will
be used for find_files, git_files and similar.
Hint: If you load a native sorter, you dont need to change this value,
the native sorter will override it anyway.
Default: require("telescope.sorters").get_fzy_sorter
*telescope.defaults.generic_sorter*
generic_sorter: ~
A function pointer to the generic sorter. The sorter that should be
used for everything that is not a file.
Hint: If you load a native sorter, you dont need to change this value,
the native sorter will override it anyway.
Default: require("telescope.sorters").get_fzy_sorter
*telescope.defaults.prefilter_sorter*
prefilter_sorter: ~
This points to a wrapper sorter around the generic_sorter that is able
to do prefiltering.
Its usually used for lsp_*_symbols and lsp_*_diagnostics
Default: require("telescope.sorters").prefilter
*telescope.defaults.file_ignore_patterns*
file_ignore_patterns: ~
A table of lua regex that define the files that should be ignored.
Example: { "^scratch/" } -- ignore all files in scratch directory
Example: { "%.npz" } -- ignore all npz files
See: https://www.lua.org/manual/5.1/manual.html#5.4.1 for more
information about lua regex
Default: nil
*telescope.defaults.file_previewer*
file_previewer: ~
Function pointer to the default file_previewer. It is mostly used
for find_files, git_files and similar.
You can change this function pointer to either use your own
previewer or use the command-line program bat as the previewer:
require("telescope.previewers").cat.new
Default: require("telescope.previewers").vim_buffer_cat.new
*telescope.defaults.grep_previewer*
grep_previewer: ~
Function pointer to the default vim_grep previewer. It is mostly
used for live_grep, grep_string and similar.
You can change this function pointer to either use your own
previewer or use the command-line program bat as the previewer:
require("telescope.previewers").vimgrep.new
Default: require("telescope.previewers").vim_buffer_vimgrep.new
*telescope.defaults.qflist_previewer*
qflist_previewer: ~
Function pointer to the default qflist previewer. It is mostly
used for qflist, loclist and lsp.
You can change this function pointer to either use your own
previewer or use the command-line program bat as the previewer:
require("telescope.previewers").qflist.new
Default: require("telescope.previewers").vim_buffer_qflist.new
*telescope.defaults.buffer_previewer_maker*
buffer_previewer_maker: ~
Developer option that defines the underlining functionality
of the buffer previewer.
For interesting configuration examples take a look at
https://github.com/nvim-telescope/telescope.nvim/wiki/Configuration-Recipes
Default: require("telescope.previewers").buffer_previewer_maker
Parameters: ~
{opts} (table) Configuration opts. Keys: defaults, pickers,
extensions

Register an extension. To be used by plugin authors.
Parameters: ~
{mod} (table) Module
telescope.load_extension({name}) *telescope.load_extension()*
Load an extension.
- Notes:
- Loading triggers ext setup via the config passed in |telescope.setup|
Parameters: ~
{name} (string) Name of the extension
telescope.extensions() *telescope.extensions()*
Use telescope.extensions to reference any extensions within your
configuration.
While the docs currently generate this as a function, it's actually a
table. Sorry.
================================================================================
*telescope.command*
Telescope commands can be called through two apis, the lua api and the viml
api.
The lua api is the more direct way to interact with Telescope, as you directly
call the lua functions that Telescope defines. It can be called in a lua file
using commands like:
`require("telescope.builtin").find_files({hidden=true, layout_config={prompt_position="top"}})`
If you want to use this api from a vim file you should prepend `lua` to the
command, as below:
`lua require("telescope.builtin").find_files({hidden=true, layout_config={prompt_position="top"}})`
If you want to use this api from a neovim command line you should prepend
`:lua` to the command, as below:
`:lua require("telescope.builtin").find_files({hidden=true, layout_config={prompt_position="top"}})`
The viml api is more indirect, as first the command must be parsed to the
relevant lua equivalent, which brings some limitations. The viml api can be
called using commands like:
`:Telescope find_files hidden=true layout_config={"prompt_position":"top"}`
This involves setting options using an `=` and using viml syntax for lists and
dictionaries when the corresponding lua function requires a table.
One limitation of the viml api is that there can be no spaces in any of the
options. For example, if you want to use the `cwd` option for `find_files` to
specify that you only want to search within the folder `/foo bar/subfolder/`
you could not do that using the viml api, as the path name contains a space.
Similarly, you could NOT set the `prompt_position` to `"top"` using the
following command:
`:Telescope find_files layout_config={ "prompt_position" : "top" }`
as there are spaces in the option.
================================================================================
*telescope.builtin*
Telescope Builtins is a collection of community maintained pickers to support
common workflows. It can be used as reference when writing PRs, Telescope
extensions, your own custom pickers, or just as a discovery tool for all of the
amazing pickers already shipped with Telescope!
Any of these functions can just be called directly by doing:
:lua require('telescope.builtin').$NAME_OF_PICKER()
To use any of Telescope's default options or any picker-specific options, call
your desired picker by passing a lua table to the picker with all of the
options you want to use. Here's an example with the live_grep picker:
>
:lua require('telescope.builtin').live_grep({
prompt_title = 'find string in open buffers...',
grep_open_files = true
})
-- or with dropdown theme
:lua require('telescope.builtin').find_files(require('telescope.themes').get_dropdown{
previewer = false
})

================================================================================
*telescope.themes*
Themes are ways to combine several elements of styling together.
They are helpful for managing the several different UI aspects for telescope
and provide a simple interface for users to get a particular "style" of picker.
themes.get_dropdown() *telescope.themes.get_dropdown()*
Dropdown style theme.
Usage:
>
`local builtin = require('telescope.builtin')`
`local themes = require('telescope.themes')`
`builtin.find_files(themes.get_dropdown())`
<
themes.get_cursor() *telescope.themes.get_cursor()*
Cursor style theme.
Usage:
>
`local builtin = require('telescope.builtin')`
`local themes = require('telescope.themes')`
`builtin.lsp_references(themes.get_cursor())`
<
themes.get_ivy() *telescope.themes.get_ivy()*
Ivy style theme.
Usage:
>
`local builtin = require('telescope.builtin')`
`local themes = require('telescope.themes')`
`builtin.find_files(themes.get_ivy())`
<
================================================================================
*telescope.layout*
The layout of telescope pickers can be adjusted using the
|telescope.defaults.layout_strategy| and |telescope.defaults.layout_config|
options. For example, the following configuration changes the default layout
strategy and the default size of the picker:
>
require('telescope').setup{
defaults = {
layout_strategy = 'vertical',
layout_config = { height = 0.95 },
},
}
<
────────────────────────────────────────────────────────────────────────────────
Layout strategies are different functions to position telescope.
All layout strategies are functions with the following signature:
>
function(picker, columns, lines, layout_config)
-- Do some calculations here...
return {
preview = preview_configuration
results = results_configuration,
prompt = prompt_configuration,
}
end
<
Parameters: ~
- picker : A Picker object. (docs coming soon)
- columns : (number) Columns in the vim window
- lines : (number) Lines in the vim window
- layout_config : (table) The configuration values specific to the picker.
This means you can create your own layout strategy if you want! Just be aware
for now that we may change some APIs or interfaces, so they may break if you
create your own.
A good method for creating your own would be to copy one of the strategies that
most resembles what you want from
"./lua/telescope/pickers/layout_strategies.lua" in the telescope repo.
layout_strategies.horizontal() *telescope.layout.horizontal()*
Horizontal layout has two columns, one for the preview and one for the
prompt and results.

- preview_width:
- Change the width of Telescope's preview window
- See |resolver.resolve_width()|
layout_strategies.center() *telescope.layout.center()*
Centered layout with a combined block of the prompt and results aligned to
the middle of the screen. The preview window is then placed in the
remaining space above or below, according to `anchor` or `mirror`.
Particularly useful for creating dropdown menus (see |telescope.themes| and
|themes.get_dropdown()|).
Note that vertical anchoring, i.e. `anchor` containing `"N"` or `"S"`, will
override `mirror` config. For `"N"` anchoring preview will be placed below
prompt/result block. For `"S"` anchoring preview will be placed above
prompt/result block. For horizontal only anchoring preview will be placed
according to `mirror` config, default is above the prompt/result block.

================================================================================
*telescope.resolve*
Provides "resolver functions" to allow more customisable inputs for options.
resolver.resolve_height() *telescope.resolve.resolve_height()*
Converts input to a function that returns the height. The input must take
one of four forms:
1. 0 <= number < 1
This means total height as a percentage.
2. 1 <= number
This means total height as a fixed number.
3. function
Must have signature: function(self, max_columns, max_lines): number
4. table of the form: {padding = `foo`}
where `foo` has one of the previous three forms.
The height is then set to be the remaining space after padding. For
example, if the window has height 50, and the input is {padding = 5},
the height returned will be `40 = 50 - 2*5`
The returned function will have signature: function(self, max_columns,
max_lines): number
resolver.resolve_width() *telescope.resolve.resolve_width()*
Converts input to a function that returns the width. The input must take
one of four forms:
1. 0 <= number < 1
This means total width as a percentage.
2. 1 <= number
This means total width as a fixed number.
3. function
Must have signature: function(self, max_columns, max_lines): number
4. table of the form: {padding = `foo`}
where `foo` has one of the previous three forms.
The width is then set to be the remaining space after padding. For
example, if the window has width 100, and the input is {padding = 5},
the width returned will be `90 = 100 - 2*5`
The returned function will have signature: function(self, max_columns,
max_lines): number
resolver.resolve_anchor_pos() *telescope.resolve.resolve_anchor_pos()*
Calculates the adjustment required to move the picker from the middle of
the screen to an edge or corner.
The `anchor` can be any of the following strings:
- "", "CENTER", "NW", "N", "NE", "E", "SE", "S", "SW", "W" The anchors
have the following meanings:
- "" or "CENTER":
the picker will remain in the middle of the screen.
- Compass directions:
the picker will move to the corresponding edge/corner e.g. "NW" -> "top
left corner", "E" -> "right edge", "S" -> "bottom edge"
================================================================================
*telescope.actions*
Actions functions that are useful for people creating their own mappings.
Actions can be either normal functions that expect the prompt_bufnr as first
argument (1) or they can be a custom telescope type called "action" (2).
(1) The `prompt_bufnr` of a normal function denotes the identifier of your
picker which can be used to access the picker state. In practice, users most
commonly access from both picker and global state via the following:
>
-- for utility functions
local action_state = require "telescope.actions.state"
local actions = {}
actions.do_stuff = function(prompt_bufnr)
local current_picker = action_state.get_current_picker(prompt_bufnr) -- picker state
local entry = action_state.get_selected_entry()
end
<
See |telescope.actions.state| for more information.
(2) To transform a module of functions into a module of "action"s, you need to
do the following:
>
local transform_mod = require("telescope.actions.mt").transform_mod
local mod = {}
mod.a1 = function(prompt_bufnr)
-- your code goes here
-- You can access the picker/global state as described above in (1).
end
mod.a2 = function(prompt_bufnr)
-- your code goes here
end
mod = transform_mod(mod)
-- Now the following is possible. This means that actions a2 will be executed
-- after action a1. You can chain as many actions as you want.
local action = mod.a1 + mod.a2
action(bufnr)
<
Another interesing thing to do is that these actions now have functions you can
call. These functions include `:replace(f)`, `:replace_if(f, c)`,
`replace_map(tbl)` and `enhance(tbl)`. More information on these functions can
be found in the `developers.md` and `lua/tests/automated/action_spec.lua` file.

================================================================================
*telescope.previewers*
Provides a Previewer table that has to be implemented by each previewer. To
achieve this, this module also provides two wrappers that abstract most of the
work and make it really easy create new previewers.
- `previewers.new_termopen_previewer`
- `previewers.new_buffer_previewer`
Furthermore, there are a collection of previewers already defined which can be
used for every picker, as long as the entries of the picker provide the
necessary fields. The more important ones are
- `previewers.cat`
- `previewers.vimgrep`
- `previewers.qflist`
- `previewers.vim_buffer_cat`
- `previewers.vim_buffer_vimgrep`
- `previewers.vim_buffer_qflist`
Previewers can be disabled for any builtin or custom picker by doing :Telescope
find_files previewer=false
previewers.Previewer() *telescope.previewers.Previewer()*
This is the base table all previewers have to implement. It's possible to
write a wrapper for this because most previewers need to have the same keys
set. Examples of wrappers are:
- `new_buffer_previewer`
- `new_termopen_previewer`
To create a new table do following:
- `local new_previewer = Previewer:new(opts)`
What `:new` expects is listed below
The interface provides following set of functions. All of them, besides
`new`, will be handled by telescope pickers.
- `:new(opts)`
- `:preview(entry, status)`
- `:teardown()`
- `:send_input(input)`
- `:scroll_fn(direction)`
`Previewer:new()` expects a table as input with following keys:
- `setup` function(self): Will be called the first time preview will be
called.
- `teardown` function(self): Will be called on cleanup.
- `preview_fn` function(self, entry, status): Will be called each time a
new entry was selected.
- `title` function(self): Will return the static title of the previewer.
- `dynamic_title` function(self, entry): Will return the dynamic title of
the previewer. Will only be called when config value
dynamic_preview_title is true.
- `send_input` function(self, input): This is meant for
`termopen_previewer` and it can be used to send input to the terminal
application, like less.
- `scroll_fn` function(self, direction): Used to make scrolling work.
previewers.new() *telescope.previewers.new()*
A shorthand for creating a new Previewer. The provided table will be
forwarded to `Previewer:new(...)`
previewers.new_termopen_previewer() *telescope.previewers.new_termopen_previewer()*
Is a wrapper around Previewer and helps with creating a new
`termopen_previewer`.
It requires you to specify one table entry `get_command(entry, status)`.
This `get_command` function has to return the terminal command that will be
executed for each entry. Example:
>
get_command = function(entry, status)
return { 'bat', entry.path }
end
<
Additionally you can define:
- `title` a static title for example "File Preview"
- `dyn_title(self, entry)` a dynamic title function which gets called when
config value `dynamic_preview_title = true`
It's an easy way to get your first previewer going and it integrates well
with `bat` and `less`. Providing out of the box scrolling if the command
uses less.
Furthermore, it will forward all `config.set_env` environment variables to
that terminal process.
previewers.cat() *telescope.previewers.cat()*
Provides a `termopen_previewer` which has the ability to display files. It
will always show the top of the file and has support for `bat`(prioritized)
and `cat`. Each entry has to provide either the field `path` or `filename`
in order to make this previewer work.
The preferred way of using this previewer is like this
`require('telescope.config').values.cat_previewer` This will respect user
configuration and will use `buffer_previewers` in case it's configured that
way.
previewers.vimgrep() *telescope.previewers.vimgrep()*
Provides a `termopen_previewer` which has the ability to display files at
the provided line. It has support for `bat`(prioritized) and `cat`. Each
entry has to provide either the field `path` or `filename` and a `lnum`
field in order to make this previewer work.
The preferred way of using this previewer is like this
`require('telescope.config').values.grep_previewer` This will respect user
configuration and will use `buffer_previewers` in case it's configured that
way.
previewers.qflist() *telescope.previewers.qflist()*
Provides a `termopen_previewer` which has the ability to display files at
the provided line or range. It has support for `bat`(prioritized) and
`cat`. Each entry has to provide either the field `path` or `filename`,
`lnum` and a `start` and `finish` range in order to make this previewer
work.
The preferred way of using this previewer is like this
`require('telescope.config').values.qflist_previewer` This will respect
user configuration and will use buffer previewers in case it's configured
that way.
previewers.new_buffer_previewer() *telescope.previewers.new_buffer_previewer()*
An interface to instantiate a new `buffer_previewer`. That means that the
content actually lives inside a vim buffer which enables us more control
over the actual content. For example, we can use `vim.fn.search` to jump to
a specific line or reuse buffers/already opened files more easily. This
interface is more complex than `termopen_previewer` but offers more
flexibility over your content. It was designed to display files but was
extended to also display the output of terminal commands.
In the following options, state table and general tips are mentioned to
make your experience with this previewer more seamless.
options:
- `define_preview = function(self, entry, status)` (required) Is called
for each selected entry, after each selection_move (up or down) and is
meant to handle things like reading file, jump to line or attach a
highlighter.
- `setup = function(self)` (optional) Is called once at the beginning,
before the preview for the first entry is displayed. You can return a
table of vars that will be available in `self.state` in each
`define_preview` call.
- `teardown = function(self)` (optional) Will be called at the end, when
the picker is being closed and is meant to cleanup everything that was
allocated by the previewer. The `buffer_previewer` will automatically
cleanup all created buffers. So you only need to handle things that
were introduced by you.
- `keep_last_buf = true` (optional) Will not delete the last selected
buffer. This would allow you to reuse that buffer in the select action.
For example, that buffer can be opened in a new split, rather than
recreating that buffer in an action. To access the last buffer number:
`require('telescope.state').get_global_key("last_preview_bufnr")`
- `get_buffer_by_name = function(self, entry)` Allows you to set a unique
name for each buffer. This is used for caching purpose.
`self.state.bufname` will be nil if the entry was never loaded or the
unique name when it was loaded once. For example, useful if you have
one file but multiple entries. This happens for grep and lsp builtins.
So to make the cache work only load content if `self.state.bufname ~=
entry.your_unique_key`
- `title` a static title for example "File Preview"
- `dyn_title(self, entry)` a dynamic title function which gets called
when config value `dynamic_preview_title = true`
`self.state` table:
- `self.state.bufnr` Is the current buffer number, in which you have to
write the loaded content. Don't create a buffer yourself, otherwise
it's not managed by the buffer_previewer interface and you will
probably be better off writing your own interface.
- self.state.winid Current window id. Useful if you want to set the
cursor to a provided line number.
- self.state.bufname Will return the current buffer name, if
`get_buffer_by_name` is defined. nil will be returned if the entry was
never loaded or when `get_buffer_by_name` is not set.
Tips:
- If you want to display content of a terminal job, use:
`require('telescope.previewers.utils').job_maker(cmd, bufnr, opts)`
- `cmd` table: for example { 'git', 'diff', entry.value }
- `bufnr` number: in which the content will be written
- `opts` table: with following keys
- `bufname` string: used for cache
- `value` string: used for cache
- `mode` string: either "insert" or "append". "insert" is default
- `env` table: define environment variables. Example:
- `{ ['PAGER'] = '', ['MANWIDTH'] = 50 }`
- `cwd` string: define current working directory for job
- `callback` function(bufnr, content): will be called when job is
done. Content will be nil if job is already loaded. So you can do
highlighting only the first time the previewer is created for
that entry. Use the returned `bufnr` and not `self.state.bufnr`
in callback, because state can already be changed at this point
in time.
- If you want to attach a highlighter use:
- `require('telescope.previewers.utils').highlighter(bufnr, ft)`
- This will prioritize tree sitter highlighting if available for
environment and language.
- `require('telescope.previewers.utils').regex_highlighter(bufnr, ft)`
- `require('telescope.previewers.utils').ts_highlighter(bufnr, ft)`
- If you want to use `vim.fn.search` or similar you need to run it in
that specific buffer context. Do
>
vim.api.nvim_buf_call(bufnr, function()
-- for example `search` and `matchadd`
end)
to achieve that.
<
- If you want to read a file into the buffer it's best to use
`buffer_previewer_maker`. But access this function with
`require('telescope.config').values.buffer_previewer_maker` because it
can be redefined by users.
previewers.buffer_previewer_maker({filepath}, {bufnr}, {opts}) *telescope.previewers.buffer_previewer_maker()*
A universal way of reading a file into a buffer previewer. It handles async
reading, cache, highlighting, displaying directories and provides a
callback which can be used, to jump to a line in the buffer.
Parameters: ~
{filepath} (string) String to the filepath, will be expanded
{bufnr} (number) Where the content will be written
{opts} (table) keys: `use_ft_detect`, `bufname` and `callback`
previewers.vim_buffer_cat() *telescope.previewers.vim_buffer_cat()*
A previewer that is used to display a file. It uses the `buffer_previewer`
interface and won't jump to the line. To integrate this one into your own
picker make sure that the field `path` or `filename` is set for each entry.
The preferred way of using this previewer is like this
`require('telescope.config').values.file_previewer` This will respect user
configuration and will use `termopen_previewer` in case it's configured
that way.
previewers.vim_buffer_vimgrep() *telescope.previewers.vim_buffer_vimgrep()*
A previewer that is used to display a file and jump to the provided line.
It uses the `buffer_previewer` interface. To integrate this one into your
own picker make sure that the field `path` or `filename` and `lnum` is set
in each entry. If the latter is not present, it will default to the first
line. The preferred way of using this previewer is like this
`require('telescope.config').values.grep_previewer` This will respect user
configuration and will use `termopen_previewer` in case it's configured
that way.
previewers.vim_buffer_qflist() *telescope.previewers.vim_buffer_qflist()*
Is the same as `vim_buffer_vimgrep` and only exist for consistency with
`term_previewers`.
The preferred way of using this previewer is like this
`require('telescope.config').values.qflist_previewer` This will respect
user configuration and will use `termopen_previewer` in case it's
configured that way.
previewers.git_branch_log() *telescope.previewers.git_branch_log()*
A previewer that shows a log of a branch as graph
previewers.git_stash_diff() *telescope.previewers.git_stash_diff()*
A previewer that shows a diff of a stash
previewers.git_commit_diff_to_parent() *telescope.previewers.git_commit_diff_to_parent()*
A previewer that shows a diff of a commit to a parent commit.
The run command is `git --no-pager diff SHA^! -- $CURRENT_FILE`
The current file part is optional. So is only uses it with bcommits.
previewers.git_commit_diff_to_head() *telescope.previewers.git_commit_diff_to_head()*
A previewer that shows a diff of a commit to head.
The run command is `git --no-pager diff --cached $SHA -- $CURRENT_FILE`
The current file part is optional. So is only uses it with bcommits.
previewers.git_commit_diff_as_was() *telescope.previewers.git_commit_diff_as_was()*
A previewer that shows a diff of a commit as it was.
The run command is `git --no-pager show $SHA:$CURRENT_FILE` or `git
--no-pager show $SHA`
previewers.git_commit_message() *telescope.previewers.git_commit_message()*
A previewer that shows the commit message of a diff.
The run command is `git --no-pager log -n 1 $SHA`
previewers.git_file_diff() *telescope.previewers.git_file_diff()*
A previewer that shows the current diff of a file. Used in git_status.
The run command is `git --no-pager diff $FILE`
previewers.display_content() *telescope.previewers.display_content()*
A deprecated way of displaying content more easily. Was written at a time,
where the buffer_previewer interface wasn't present. Nowadays it's easier
to just use this. We will keep it around for backwards compatibility
because some extensions use it. It doesn't use cache or some other clever
tricks.
================================================================================
*telescope.actions.history*
A base implementation of a prompt history that provides a simple history and
can be replaced with a custom implementation.
