|
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 features such as tabs or splits (which can be
|
|
better provided by a window manager or [terminal multiplexer][tmux]) nor
|
|
niceties like a GUI config editor.
|
|
|
|
The software is considered to be at an **alpha** level of readiness--there are
|
|
missing features and bugs to be fixed, but it is already used by many as a daily
|
|
driver.
|
|
|
|
Precompiled binaries will eventually be made available on supported platforms.
|
|
This is minimally blocked on a stable config format. For now, Alacritty must be
|
|
built from source.

## Installation
|
|
|
|
Instructions are provided for macOS and many Linux variants to compile Alacritty
|
|
from source. With the exception of Arch (which has a package in the AUR), Void Linux (in main repository) and
|
|
[NixOS](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/misc/alacritty/default.nix)
|
|
(at the moment in unstable, will be part of 17.09), please first read the
|
|
[prerequisites](#prerequisites) section, then find the section for your OS, and
|
|
finally go to [building](#building) and [configuration](#configuration).

## Manual Installation
|
|
|
|
### Prerequisites
|

|
|
|
|
```sh
|
|
zypper install cmake freetype-devel fontconfig-devel xclip
|
|
```
|
|
|
|
#### Slackware
|
|
|
|
Compiles out of the box for 14.2
|
|

|
|
compiling Alacritty:
|
|
|
|
```sh
|
|
xbps-install cmake freetype-devel freetype expat-devel fontconfig xclip
|
|
```
|
|
|
|
#### FreeBSD
|
|
|
|
On FreeBSD, you need a few extra libraries to build Alacritty. Here's a `pkg`
|
|
command that should install all of them. If something is still found to be
|
|
missing, please open an issue.
|
|
|
|

```
|
|
|
|
### NixOS/Nixpkgs
|
|
|
|
The following command can be used to get a shell with all development
|
|
dependencies on [NixOS](https://nixos.org).
|
|
|
|
```sh
|
|
nix-shell -A alacritty '<nixpkgs>'
|
|
```
|
|
|
|
#### Gentoo
|
|
|
|
On Gentoo, there's a portage overlay available. Make sure `layman` is installed
|
|
and run:
|
|
|
|
```sh
|
|
sudo layman -a slyfox
|
|
```
|
|
|
|
Then, add `x11-terms/alacritty **` to `/etc/portage/package.accept_keywords` and
|
|
emerge alacritty:
|
|
|
|
```sh
|
|
sudo emerge alacritty
|
|
```
|
|
|
|
It might be handy to mask all other packages provided in the `slyfox` overlay by
|
|
adding `*/*::slyfox` to `/etc/portage/package.mask` and adding
|
|
`x11-terms/alacritty::slyfox` to `/etc/portage/package.unmask`.
|
|
|
|
#### Other
|
|
|
|
If you build Alacritty on another distribution, we would love some help
|
|
filling in this section of the README.
|
|
|
|
### Building
|
|
|
|
Once all the prerequisites are installed, compiling Alacritty should be easy:
|
|
|
|
```sh
|
|
cargo build --release
|
|
```
|
|
|
|
If all goes well, this should place a binary at `target/release/alacritty`.
|
|
**BEFORE YOU RUN IT:** Install the config file as described below; otherwise,
|
|
many things (such as arrow keys) will not work.
|
|
|
|
### Desktop Entry
|
|
|
|
Many linux distributions support desktop entries for adding applications to
|
|
system menus. To install the desktop entry for Alacritty, run
|
|
|
|
```sh
|
|
sudo cp target/release/alacritty /usr/local/bin # or anywhere else in $PATH
|
|
cp Alacritty.desktop ~/.local/share/applications
|
|
```
|
|
|
|
To build an application for macOS, run
|
|
|
|
```sh
|
|
make app
|
|
cp -r target/release/osx/Alacritty.app /Applications/
|
|
```
|
|
|
|
## Configuration
|
|
|
|
Although it's possible the default configuration would work on your system,
|
|
you'll probably end up wanting to customize it anyhow. There is a default
|
|
`alacritty.yml` at the git repository root. Alacritty looks for the
|
|
configuration file as the following paths:
|
|
|
|
1. `$XDG_CONFIG_HOME/alacritty/alacritty.yml`
|
|
2. `$XDG_CONFIG_HOME/alacritty.yml`
|
|
3. `$HOME/.config/alacritty/alacritty.yml`
|
|
4. `$HOME/.alacritty.yml`
|
|
|
|
If none of these paths are found then
|
|
`$XDG_CONFIG_HOME/alacritty/alacritty.yml` is created once alacritty is first
|
|
run. On most systems this often defaults to
|
|
`$HOME/.config/alacritty/alacritty.yml`.
|
|
|
|
Many configuration options will take effect immediately upon saving changes to
|
|
the config file. The only exception is the `font` and `dimensions` sections
|
|
which requires Alacritty to be restarted. For further explanation of the config
|
|
file, please consult the comments in the default config file.
|
|
|
|
## Issues (known, unknown, feature requests, etc)
|
|
|
|
If you run into a problem with Alacritty, please file an issue. If you've got a
|
|
feature request, feel free to ask about it. Keep in mind that Alacritty is very
|
|
much not looking to be a feature-rich terminal emulator with all sorts of bells
|
|
and widgets. It's primarily a cross-platform, blazing fast `tmux` renderer that
|
|
Just Works.
|
|
|
|
## FAQ
|
|
|
|
- _Is it really the fastest terminal emulator?_ In the terminals I've
|
|
benchmarked against, alacritty is either faster, WAY faster, or at least
|
|
neutral. There are no benchmarks in which I've found Alacritty to be slower.
|
|
- _macOS + tmux + vim is slow! I thought this was supposed to be fast!_ This
|
|
appears to be an issue outside of terminal emulators; either macOS has an IPC
|
|
performance issue, or either tmux or vim (or both) have a bug. This same issue
|
|
can be seen in `iTerm2` and `Terminal.app`. I've found that if tmux is running
|
|
on another machine which is connected to Alacritty via SSH, this issue
|
|
disappears. Actual throughput and rendering performance are still better in
|
|
Alacritty.
|
|
- _When will Windows support be available?_ When someone has time to work on it.
|
|
Contributors would be welcomed :).
|
|
- _My arrow keys don't work_. It sounds like you deleted some key bindings from
|
|
your config file. Please reference the default config file to restore them.
|
|
- _Why doesn't it support scrollback?_ Alacritty's original purpose was to
|
|
provide a better experience when using [tmux] which already handled
|
|
scrollback. The scope of this project has since expanded, and [scrollback will
|
|
eventually be added](https://github.com/jwilm/alacritty/issues/124).

Alacritty discussion can be found in `#alacritty` on freenode.

|
|
|
## Wayland
|
|
|
|
Wayland support is available, but not everything works as expected. Many people
|
|
have found a better experience using XWayland which can be achieved launching
|
|
Alacritty with the `WAYLAND_DISPLAY` environment variable cleared:
|
|
|
|
```sh
|
|
env WAYLAND_DISPLAY= alacritty
|
|
```
|
|
|
|
If you're interested in seeing our Wayland support improve, please head over to
|
|
the [Wayland meta issue] on the _winit_ project to see how you may contribute.
