Alacritty Terminal Configuration and Usage

Introduction

Alacritty is a contemporary terminal emulator, characterized by sensible defaults yet allowing for extensive customization. By integrating with other applications, rather than reimplementing their functionalities, it offers a flexible and high-performance feature set. The currently supported platforms encompass BSD, Linux, macOS, and Windows.

Installation

If modification of the icon is not required, direct download is recommended:

• Directly download the officially compiled installation package: https://alacritty.org/index.html

• Manual Compilation Here, because the source code's icon is square with right angles and does not quite align with the macOS icon style, I have personally forked a version with a modified icon, thus necessitating manual compilation.

Install the Rust and Make environments:

bash
# Install the Rust environment; if it already exists, this step can be skipped.
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

brew install make

bash
 # Shallow clone the repository code.
git clone --depth 1 https://github.com/KevinYouu/alacritty.git

cd alacritty

# Compile for the current architecture.
make dmg

# Compile the universal architecture for macOS.
# dmg-universal

Subsequently, the compiled application and DMG file can be located in the alacritty/target/release/osx directory. Simply place these into /Applications for immediate use.

Configuration

The following is my personalized configuration file:

toml
[window]
dimensions = { columns = 80, lines = 24 }
padding = { x = 4, y = 0 }
opacity = 0.2
blur = true

[font]
normal = { family = "Roboto Mono", style = "Regular" }
bold = { family = "Roboto Mono", style = "bold" }
italic = { family = "Roboto Mono", style = "italic" }
bold_italic = { family = "Roboto Mono", style = "bold italic" }
size = 18

[selection]
save_to_clipboard = true
semantic_escape_chars = ",│`|:\"' ()[]{}<>\t"

[cursor]
style = { shape = "Beam", blinking = "On" }

[terminal]
shell = { program = "/opt/homebrew/bin/fish", args = ["-l"] }

[colors.primary]

green = "#4cd964"
yellow = "#ffcc00"

[keyboard]
bindings = [
    # Copy (Cmd + C)
    { key = "C", mods = "Command", action = "Copy" },

    # Paste (Cmd + V)
    { key = "V", mods = "Command", action = "Paste" },

    { key = "N", mods = "Command", action = "CreateNewWindow" },

    # Decrease Font Size (Cmd + -)
    { key = "Minus", mods = "Command", action = "DecreaseFontSize" },

    # Increase Font Size (Cmd + =)
    { key = "Equals", mods = "Command", action = "IncreaseFontSize" },

    # Reset Font Size (Cmd + 0)
    { key = "Key0", mods = "Command", action = "ResetFontSize" },

    # Toggle Full Screen (Cmd + Enter)
    { key = "Return", mods = "Command", action = "ToggleSimpleFullscreen" },

    # Switch to Specific Tab (Cmd + 1 ~ Cmd + 9)
    { key = "Key1", mods = "Command", action = "SelectTab1" },
    { key = "Key2", mods = "Command", action = "SelectTab2" },
    { key = "Key3", mods = "Command", action = "SelectTab3" },
    { key = "Key4", mods = "Command", action = "SelectTab4" },
    { key = "Key5", mods = "Command", action = "SelectTab5" },
    { key = "Key6", mods = "Command", action = "SelectTab6" },
    { key = "Key7", mods = "Command", action = "SelectTab7" },
    { key = "Key8", mods = "Command", action = "SelectTab8" },
    { key = "Key9", mods = "Command", action = "SelectTab9" },

    # Hide Alacritty (Cmd + H)
    { key = "H", mods = "Command", action = "Hide" },

    # Hide Other Applications (Cmd + Option + H)
    { key = "H", mods = "Command|Option", action = "HideOtherApplications" },
]
