# Configuration for Alacritty, the GPU enhanced terminal emulator

  #
  # If this property is not set, alacritty will set it to xterm-256color.
  #
  # Note that some xterm terminfo databases don't declare support for italics.
  # You can verify this by checking for the presence of `smso` and `sitm` in
  # `infocmp xterm-256color`.

  # Faux Scrolling
  #
  # The `faux_multiplier` setting controls the number

  #
  # To disable this completely, set `faux_multiplier` to 0.

#
# This setting defines the width of a tab in cells. Changes to this
# value require a restart to take effect.
#
# 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.

# Font configuration (changes require restart)
#
# Important font attributes like antialiasing, subpixel aa, and hinting can be
# controlled through fontconfig. Specifically, the following attributes should
# have an effect:
#
# * hintstyle
# * antialias
# * lcdfilter
# * rgba
#
# For instance, if you wish to disable subpixel antialiasing, you might set the
# rgba property to "none". If you wish to completely disable antialiasing, you
# can set antialias to false.
#
# Please see these resources for more information on how to use fontconfig

# 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.
#
# Possible values for `animation`

#   args:
#     - --login

# Key bindings
#
# Each binding is defined as an object with some properties. Most of the
# properties are optional. All of the alphabetical keys should have a letter for
# the `key` value such as `V`. Function keys are probably what you would expect
# as well (F1, F2, ..). The number keys above the main keyboard are encoded as
# `Key1`, `Key2`, etc. Keys on the number pad are encoded `Number1`, `Number2`,
# etc.  These all match the glutin::VirtualKeyCode variants.
#
# A list with all available `key` names can be found here:
# https://docs.rs/glutin/*/glutin/enum.VirtualKeyCode.html#variants
#
# Possible values for `mods`
# `Command`, `Super` refer to the super/command/windows key
# `Control` for the control key
# `Shift` for the Shift key
# `Alt` and `Option` refer to alt/option
#
# mods may be combined with a `|`. For example, requiring control and shift
# looks like:
#
# mods: Control|Shift
#
# The parser is currently quite sensitive to whitespace and capitalization -
# capitalization must match exactly, and piped items must not have whitespace
# around them.
#
# Either an `action`, `chars`, or `command` field must be present.
#   `action` must be one of the following:
#       - `Paste`
#       - `PasteSelection`
#       - `Copy`
#       - `IncreaseFontSize`
#       - `DecreaseFontSize`
#       - `ResetFontSize`
#       - `ScrollPageUp`
#       - `ScrollPageDown`
#       - `ScrollToTop`
#       - `ScrollToBottom`
#       - `Quit`
#   `chars` writes the specified string every time that binding is activated.
#     These should generally be escape sequences, but they can be configured to
#     send arbitrary strings of bytes.
#   `command` must be a map containing a `program` string, and `args` array of
#     strings. For example:
#     - { ... , command: { program: "alacritty", args: ["-e", "vttest"] } }
#
# Want to add a binding (e.g. "PageUp") but are unsure what the X sequence
# (e.g. "\x1b[5~") is? Open another terminal (like xterm) without tmux,
# then run `showkey -a` to get the sequence associated to a key combination.
