Qin's Alacritty Configuration on macOS

alacritty.yml

# Configuration for Alacritty, the GPU enhanced terminal emulator.

# Any items in the `env` entry below will be added as
# environment variables. Some entries may override variables
# set by alacritty itself.
#env:
  # TERM variable
  #
  # This value is used to set the `$TERM` environment variable for
  # each instance of Alacritty. If it is not present, alacritty will
  # check the local terminfo database and use `alacritty` if it is
  # available, otherwise `xterm-256color` is used.
  #TERM: xterm-256color

window:
  # Window dimensions (changes require restart)
  #
  # Specified in number of columns/lines, not pixels.
  # If both are `0`, this setting is ignored.
  dimensions:
    columns: 0
    lines: 0

  # Window position (changes require restart)
  #
  # Specified in number of pixels.
  # If the position is not set, the window manager will handle the placement.
  #position:
  #  x: 0
  #  y: 0

  # Window padding (changes require restart)
  #
  # Blank space added around the window in pixels. This padding is scaled
  # by DPI and the specified value is always added at both opposing sides.
  padding:
    x: 0
    y: 0

  # Spread additional padding evenly around the terminal content.
  dynamic_padding: false

  # Window decorations
  #
  # Values for `decorations`:
  #     - full: Borders and title bar
  #     - none: Neither borders nor title bar
  #
  # Values for `decorations` (macOS only):
  #     - transparent: Title bar, transparent background and title bar buttons
  #     - buttonless: Title bar, transparent background, but no title bar buttons
  decorations: full

  # Startup Mode (changes require restart)
  #
  # Values for `startup_mode`:
  #   - Windowed
  #   - Maximized
  #   - Fullscreen
  #
  # Values for `startup_mode` (macOS only):
  #   - SimpleFullscreen
  startup_mode: Maximized

  # Window title
  #title: Alacritty

  # Window class (Linux only):
  #class: Alacritty

scrolling:
  # Maximum number of lines in the scrollback buffer.
  # Specifying '0' will disable scrolling.
  history: 10000

  # Number of lines the viewport will move for every line scrolled when
  # scrollback is enabled (history > 0).
  multiplier: 3

  # Faux Scrolling
  #
  # The `faux_multiplier` setting controls the number of lines the terminal
  # should scroll when the alternate screen buffer is active. This is used
  # to allow mouse scrolling for applications like `man`.
  #
  # Specifying `0` will disable faux scrolling.
  faux_multiplier: 3

  # Scroll to the bottom when new text is written to the terminal.
  auto_scroll: false

# Spaces per Tab (changes require restart)
#
# This setting defines the width of a tab in cells.
#
# Some applications, like Emacs, rely on knowing about the width of a tab.
# To prevent unexpected behavior in these applications, it's also required to
# change the `it` value in terminfo when altering this setting.
tabspaces: 4

  # Offset is the extra space around each character. `offset.y` can be thought of
  # as modifying the line spacing, and `offset.x` as modifying the letter spacing.
  offset:
    x: 0
    y: 0

  # Glyph offset determines the locations of the glyphs within their cells with

  # Thin stroke font rendering (macOS only)
  #
  # Thin strokes are suitable for retina displays, but for non-retina screens

  #
  # macOS >= 10.14.x:
  #
  # If the font quality on non-retina display looks bad then set
  # `use_thin_strokes` to `true` and enable font smoothing by running the
  # following command:
  #   `defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO`
  #
  # This is a global setting and will require a log out or restart to take
  # effect.

# Visual Bell
#
# Any time the BEL code is received, Alacritty "rings" the visual bell. Once
# rung, the terminal background will be set to white and transition back to the
# default background color. You can control the rate of this transition by
# setting the `duration` property (represented in milliseconds). You can also
# configure the transition function by setting the `animation` property.

# Windows 10 ConPTY backend (Windows only)

# Key bindings
#
# Key bindings are specified as a list of objects. Each binding will specify a
# key and modifiers required to trigger it, terminal modes where the binding is
# applicable, and what should be done when the key binding fires. It can either
# send a byte sequence to the running application (`chars`), execute a
# predefined action (`action`) or fork and execute a specified command plus
# arguments (`command`).
#
# Bindings are always filled by default, but will be replaced when a new binding
# with the same triggers is defined. To unset a default binding, it can be
# mapped to the `None` action.
#
# Example:
#   `- { key: V, mods: Control|Shift, action: Paste }`
#
# Available fields:
#   - key
#   - mods (optional)
#   - chars | action | command (exactly one required)
#   - mode (optional)
#
# Values for `key`:
#   - `A` -> `Z`
#   - `F1` -> `F12`
#   - `Key1` -> `Key0`
#
#   A full list with available key codes can be found here:
#   https://docs.rs/glutin/*/glutin/enum.VirtualKeyCode.html#variants
#
#   Instead of using the name of the keys, the `key` field also supports using
#   the scancode of the desired key. Scancodes have to be specified as a
#   decimal number.
#   This command will allow you to display the hex scancodes for certain keys:
#     `showkey --scancodes`
#
# Values for `mods`:
#   - Command
#   - Control
#   - Option
#   - Super
#   - Shift
#   - Alt
#
#   Multiple `mods` can be combined using `|` like this: `mods: Control|Shift`.
#   Whitespace and capitalization is relevant and must match the example.
#
# Values for `chars`:
#   The `chars` field writes the specified string to the terminal. This makes
#   it possible to pass escape sequences.
#   To find escape codes for bindings like `PageUp` ("\x1b[5~"), you can run
#   the command `showkey -a` outside of tmux.
#   Note that applications use terminfo to map escape sequences back to
#   keys. It is therefore required to update the terminfo when
#   changing an escape sequence.
#
# Values for `action`:
#   - Paste
#   - PasteSelection
#   - Copy
#   - IncreaseFontSize
#   - DecreaseFontSize
#   - ResetFontSize
#   - ScrollPageUp
#   - ScrollPageDown
#   - ScrollLineUp
#   - ScrollLineDown
#   - ScrollToTop
#   - ScrollToBottom
#   - ClearHistory
#   - Hide
#   - Quit
#   - ClearLogNotice
#   - SpawnNewInstance
#   - ToggleFullscreen
#   - None
#
# Values for `action` (macOS only):
#   - ToggleSimpleFullscreen: Enters fullscreen without occupying another space
#
# Values for `command`:
#   The `command` field must be a map containing a `program` string and
#   an `args` array of command line parameter strings.
#
#   Example:
#       `command: { program: "alacritty", args: ["-e", "vttest"] }`
#
# Values for `mode`:
#   - ~AppCursor
#   - AppCursor
#   - ~AppKeypad
#   - AppKeypad
