# 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

# configure the transition function by setting the `animation` property.

# 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 `Paste`, `PasteSelection`, `Copy`, or `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"] } }
key_bindings:
  # - { key: N,        mods: Command, command: { program: "open", args: ["-n", "/Applications/Alacritty.app"] } }

How'd you find the font names? I'm typing them verbatim from the Terminal app but Alacritty can't find them.

Hm, not sure.

For finding the exact name of fonts, MacOS has an application called Font Book that may help.

I'll note that this config file may be out of date -- I don't use Alacritty anymore (I switched to Kitty). You might want to work off the current config example.

But I'll take some guesses: Are you setting the font name to the variable family? I remember finding that odd at the time. Maybe try single quotes instead of double? Make sure font is installed correctly. Could try commenting in or out the style: Regular line...

Hey, thanks for the reply. I think your config is pretty good as an example still.

I was trying to use some obscure, patched vim font and ended up doing a giant find command and going down a rabbit hole (apparently fc-list isn't a mac thing). Anyway, it was family: TerminessTTF Nerd Font Mono

Strangely, the style is style: Medium
