Alacritty - GPU 가속 터미널

성능, 설정, Vi 모드 생산성을 위한 궁극의 Alacritty 참고 자료

Alacritty는 Rust로 작성된 놀라울 정도로 빠른 GPU 가속 터미널 에뮬레이터입니다. 성능과 단순성을 염두에 두고 설계된 Alacritty는 한 가지 일을 특별히 잘 수행하는 데 집중합니다: 가능한 가장 빠른 터미널 경험을 제공하는 것입니다. 기능이 많은 터미널과 달리, Alacritty는 창 관리, 탭, 멀티플렉싱을 외부 도구에 위임하여 비교할 수 없는 속도와 효율성을 달성할 수 있습니다. 이 포괄적인 치트 시트는 Alacritty로 생산성을 최대화하기 위한 필수 단축키, 구성 옵션, Vi 모드 기능을 다룹니다.
