ALACRITTY(5)

# NAME

Alacritty - TOML configuration file format

# SYNTAX

Alacritty's configuration file uses the TOML format. The format's specification
can be found at _https://toml.io/en/v1.0.0_.

# GENERAL

This section documents the root level of the configuration file.

*import* [<string>,]

	Import additional configuration files

	Imports are loaded in order, skipping all missing files, with the importing
	file being loaded last. If a field is already present in a previous import,
	it will be replaced.

	All imports must either be absolute paths starting with _/_, or paths
	relative to the user's home directory starting with _~/_.

	Example:
		import = [++

]

*shell* <string> | { program = <string>, args = [<string>,] }

	You can set _shell.program_ to the path of your favorite shell, e.g.
	_/bin/zsh_. Entries in _shell.args_ are passed as arguments to the shell.

	Default:
		Linux/BSD/macOS: _$SHELL_ or the user's login shell, if _$SHELL_ is unset++
Windows: _"powershell"_

	Example:
		*[shell]*++
program = _"/bin/zsh"_++
args = [_"-l"_]

*working_directory* <string> | "None"

	Directory the shell is started in. When this is unset, or _"None"_, the
	working directory of the parent process will be used.

WINIT_X11_SCALE_FACTOR = _"1.0"_

# WINDOW

This section documents the *[window]* table of the configuration file.

*dimensions* { columns = <integer>, lines = <integer> }

	Window dimensions (changes require restart)

	Number of lines/columns (not pixels) in the terminal. Both lines and columns
	must be non-zero for this to take effect. The number of columns must be at

# Terminal

This section documents the *[terminal]* table of the configuration file.

*osc52* "Disabled" | "OnlyCopy" | "OnlyPaste" | "CopyPaste"

	Controls the ability to write to the system clipboard with the _OSC 52_
	escape sequence. While this escape sequence is useful to copy contents
	from the remote server, allowing any application to read from the clipboard
	can be easily abused while not providing significant benefits over
	explicitly pasting text.

	Default: _"OnlyCopy"_

# Mouse

This section documents the *[mouse]* table of the configuration file.

*hide_when_typing* <boolean>

	When this is _true_, the cursor is temporarily hidden when typing.

	Default: _false_

*bindings*: [{ <mouse>, <mods>, <mode>, <action> | chars = <string> },]

	See _keyboard.bindings_ for full documentation on _mods_, _mode_, _action_,
	and _chars_.

	To trigger mouse bindings when an application running within Alacritty
	captures the mouse, the `Shift` modifier is automatically added as a
	requirement.

	*mouse* "Middle" | "Left" | "Right" | "Back" | "Forward" | <number>

		Mouse button which needs to be pressed to trigger this binding.

	*action* <keyboard.bindings.action> | "ExpandSelection"

		*ExpandSelection*
			Expand the selection to the current mouse cursor location.

	Example:
		*[mouse]*++
bindings = [++
	{ mouse = _"Right"_, mods = _"Control"_, action = _"Paste"_ },++
]

# Hints

This section documents the *[hints]* table of the configuration file.

Terminal hints can be used to find text or hyperlinks in the visible part of the
terminal and pipe it to other applications.

*alphabet* <string>

	Keys used for the hint labels.

	Default: _"jfkdls;ahgurieowpq"_

*enabled* [{ <regex>, <hyperlinks>, <post_processing>, <persist>, <action>, <command> <binding>, <mouse> },]

Array with all available hints.

Each hint must have at least one of _regex_ or _hyperlinks_ and either an
_action_ or a _command_.

	*regex* <string>

		Regex each line will be compared against.

	*hyperlinks* <boolean>

		When this is _true_, all OSC 8 escape sequence hyperlinks will be
		included in the hints.

	*post_processing* <boolean>

		When this is _true_, heuristics will be used to shorten the match if
		there are characters likely not to be part of the hint (e.g. a trailing
		_._). This is most useful for URIs and applies only to _regex_ matches.

	*persist* <boolean>

		When this is _true_, hints remain persistent after selection.

	*action* "Copy" | "Paste" | "Select" | "MoveViModeCursor"

		*Copy*
			Copy the hint's text to the clipboard.
		*Paste*
			Paste the hint's text to the terminal or search.
		*Select*
			Select the hint's text.
		*MoveViModeCursor*
			Move the vi mode cursor to the beginning of the hint.

	*command* <string> | { program = <string>, args = [<string>,] }

		Command which will be executed when the hint is clicked or selected with
		the _binding_.

		The hint's text is always attached as the last argument.

	*binding* { key = <string>, mods = <string>, mode = <string> }

		See _keyboard.bindings_ for documentation on available values.

		This controls which key binding is used to start the keyboard hint
		selection process.

	*mouse* { mods = <string>, enabled = <boolean> }

		See _keyboard.bindings_ for documentation on available _mods_.

		The _enabled_ field controls if the hint should be underlined when
		hovering over the hint text with all _mods_ pressed.

Default: _[{
	regex = "(ipfs:|ipns:|magnet:|mailto:|gemini://|gopher://|https://|http://|news:|file:|git://|ssh:|ftp://)[^\\u0000-\\u001F\\u007F-\\u009F<>\\"\\\\s{-}\\\\^⟨⟩`]+",++
hyperlinks = true,++
post_processing = true,++
persist = false,++
mouse = { enabled = true },++
binding = { key = "U", mods = "Control | Shift" },
}]_

# Keyboard

This section documents the *[keyboard]* table of the configuration file.

*bindings*: [{ <key>, <mods>, <mode>, <action> | chars = <string> },]

	To unset a default binding, you can use the action _"ReceiveChar"_ to remove
	it or _"None"_ to inhibit any action.

	Multiple keybindings can be triggered by a single key press and will be
	executed in the order they are defined in.

	*key* <string>

		The regular keys like _"A"_, _"0"_, and _"Я"_ can be mapped directly
		without any special syntax. Full list of named keys like _"F1"_ and the
		syntax for dead keys can be found here:++
https://docs.rs/winit/\*/winit/keyboard/enum.Key.html

		Numpad keys are prefixed by _Numpad_: "NumpadEnter" | "NumpadAdd" |
		"NumpadComma" | "NumpadDivide" | "NumpadEquals" | "NumpadSubtract" |
		"NumpadMultiply" | "Numpad[0-9]".

		The _key_ field also supports using scancodes, which are specified as a
		decimal number.

	*mods* "Command" | "Control" | "Option" | "Super" | "Shift" | "Alt"

		Multiple modifiers can be combined using _|_, like this: _"Control |
		Shift"_.

	*mode* "AppCursor" | "AppKeypad" | "Search" | "Alt" | "Vi"

		This defines a terminal mode which must be active for this binding to
		have an effect.

		Prepending _~_ to a mode will require the mode to *not* be active for
		the binding to take effect.

		Multiple modes can be combined using _|_, like this: _"~Vi|Search"_.
