Alacritty ========= [![Build Status](https://travis-ci.org/jwilm/alacritty.svg?branch=master)](https://travis-ci.org/jwilm/alacritty) Alacritty is the fastest terminal emulator in existence. Using the GPU for rendering enables optimizations that simply aren't possible in other emulators. Alacritty currently supports macOS and Linux, and Windows support is planned before the 1.0 release.

## About Alacritty is focused on simplicity and performance. The performance goal means it should be faster than any other terminal emulator available. The simplicity goal means that it doesn't have many features like tabs or scroll back as in other terminals. Instead, it is expected that users of Alacritty make use of a terminal multiplexer such as [`tmux`](https://github.com/tmux/tmux). This initial release should be considered to be **pre-alpha** software--it will have issues. Once Alacritty reaches an alpha level of readiness, precompiled binaries will be provided for supported operating systems. ## Further information - [Announcing Alacritty, a GPU-Accelerated Terminal Emulator](http://blog.jwilm.io/announcing-alacritty/) January 6, 2017 - [A short talk about Alacritty at the Rust Meetup January 2017](https://air.mozilla.org/rust-meetup-january-2017/) (starts at 57:00) ## Installation The only supported installation method at this time is from source. Proper installers will be added prior to the 1.0 release of Alacritty. This section will walk you through how to build from source on both macOS and Ubuntu. ### Prerequisites 1. Install [`rustup.rs`](https://rustup.rs/) 2. Clone the source code: ```sh git clone https://github.com/jwilm/alacritty cd alacritty ``` 3. Make sure you have the right Rust compiler installed. Alacritty requires nightly Rust. Run ```sh rustup override set nightly ``` If you run into problems, you can try a known-good version of the compiler by running ```sh rustup override set $(
