Alacritty - GPU-Beschleunigter Terminal¶
Ultimative Alacritty-Referenz für Leistung, Konfiguration und Vi-Modus-Produktivität
Alacritty ist ein blitzschneller, GPU-beschleunigter Terminal-Emulator, der in Rust geschrieben wurde. Entwickelt mit Fokus auf Leistung und Einfachheit, konzentriert sich Alacritty darauf, eine Sache außergewöhnlich gut zu machen: die schnellstmögliche Terminal-Erfahrung zu bieten. Im Gegensatz zu funktionsreichen Terminals delegiert Alacritty Fensterverwaltung, Tabs und Multiplexing an externe Tools, um unübertroffene Geschwindigkeit und Effizienz zu erreichen. Diese umfassende Cheat Sheet deckt wesentliche Shortcuts, Konfigurationsoptionen und Vi-Modus-Funktionen ab, um Ihre Produktivität mit Alacritty zu maximieren.

# Use online TOML validators or:
python3 -c "import toml; toml.load('~/.config/alacritty/alacritty.toml')"
Tipps und Best Practices¶
Performance-Tipps¶
# Optimal settings for performance
[scrolling]
history = 5000 # Reasonable scrollback
multiplier = 3 # Smooth scrolling
[font]
size = 12.0 # Smaller fonts are faster
[window]
dynamic_padding = false # Disable for performance
Workflow-Integration¶
# Use with terminal multiplexers
# Tmux for session management
# Screen for simple multiplexing
# Combine with window managers
# i3, sway, or dwm for tiling
# Use Alacritty as default terminal
# Shell configuration
# Optimize shell startup time
# Use fast prompts (starship, pure)
