Alacritty is a fast, GPU-accelerated terminal emulator. Alacritty is written in Rust and uses the GPU to render text, making it much faster than other terminal emulators. Alacritty also has a very small footprint, making it ideal for systems with limited resources.
Alacritty is configured using a TOML file. The TOML file is located in your home directory at ~/.config/alacritty/alacritty.yml. Alacritty uses TOML because it is a simple and easy-to-use syntax. The TOML file contains all the settings for Alacritty, including the font, colors, and key bindings.
How do I configure Alacritty?
To configure Alacritty, you need to edit the ~/.config/alacritty/alacritty.yml file.
Font
The font setting specifies the font that Alacritty will use. The font can be a font family name or a path to a font file.
font:
normal:
family: "JetBrains Mono"
style: Regular
bold:
family: "JetBrains Mono"
style: Bold
This example sets the default font to JetBrains Mono, with Regular style for normal characters and Bold style for bold characters.
Colors
The colors setting specifies the colors that Alacritty will use. You can set the colors for the foreground, background, and various other elements.
colors:
primary:
background: "#282c34"
foreground: "#abb2bf"
normal:
black: "#21252b"
red: "#e06c75"
green: "#98c379"
yellow: "#d19a66"
blue: "#61afef"
magenta: "#c678dd"
cyan: "#56b6c2"
white: "#abb2bf"
This example sets the primary color scheme, which includes the background and foreground colors. It also defines the normal colors, which are used for text, cursor, and other elements.
Key Bindings
The key_bindings setting specifies the key bindings that Alacritty will use. You can customize the key bindings to suit your needs.
key_bindings:
- { key: "F1", action: "Copy" }
- { key: "F2", action: "Paste" }
- { key: "F3", action: "Find" }
- { key: "F4", action: "NextMatch" }
- { key: "F5", action: "PreviousMatch" }
- { key: "F6", action: "GoToStartOfLine" }
- { key: "F7", action: "GoToEndOfLine" }
- { key: "F8", action: "Clear" }
- { key: "F9", action: "SplitPaneVertical" }
- { key: "F10", action: "SplitPaneHorizontal" }
This example defines key bindings for various common actions, like Copy, Paste, Find, NextMatch, PreviousMatch, GoToStartOfLine, GoToEndOfLine, Clear, and SplitPaneVertical and SplitPaneHorizontal.
