Alacritty is a simple, GPU-accelerated terminal emulator written in Rust. It supports scrollback, truecolor, copy/paste, clicking on URLS, and custom key bindings.

Installation

Alacritty のインストール. ターミナルを iTerm2 から Alacritty に乗り換えた。 インストール. MacOS でインストールしたい場合は、 $ brew cask install alacritty 日本語表示. 日本語が表示されなかったので、下記追加。.zshrc export LANG=jaJP.UTF-8 設定変更. This simple tutorial shows how to install the fastest terminal emulator, Alacritty, in Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20 via PPA. Alacritty is a cross-platform, GPU-accelerated terminal emulator works on macOS, Linux, BSD, and Windows. It’s free and open-source software that strongly focus on simplicity and performance. I run command in Alacritty, waited to finish and the run in GNOME terminal and the results are next, 23.330s for the Alacritty and 31.844s for the GNOME terminal. I run this test couple of time and every time Alacritty was faster, except once when Alacritty needed a full minute(don’t know why and didn’t happen again).

1. I’m on Mac, so this install guide is Mac-centric, but see the Alacritty repo for more installation instructions. Since Alacritty is a GUI app (icon in the Applications directory), in Homebrew-land this means it’s a 'cask', and has to be installed with the -cask flag: $ brew install -cask -no-quarantine alacritty.
2. Alacritty can be installed using package managers on Linux, BSD, macOS and Windows. To install Alacritty on Linux, run the following commands depending on your distribution. Note that some distributions already include Alacritty binaries in their repository. If not you can run the below commands to install.

Install the alacritty package or alacritty-git^AUR for the development version.

Configuration

Install Alacrity Terminal For Macos Sierra

Alacritty searches for a configuration file at the following places in this order:

• $XDG_CONFIG_HOME/alacritty/alacritty.yml
• $XDG_CONFIG_HOME/alacritty.yml
• $HOME/.config/alacritty/alacritty.yml
• $HOME/.alacritty.yml

Copy the example configuration file at /usr/share/doc/alacritty/example/alacritty.yml to one of those places and uncomment the settings you want to change. Most settings take effect as soon as you save the file.

Colors

See the upstream wiki for a list of available color schemes. If your preferred color scheme is on the list, paste the provided code into your configuration file.

Font

If you do not want to use your system’s default font, you can specify a different font by changing the following lines:

Substitute monospace with a font name from the output of

Note that some fonts do not provide an Italic style but an Oblique style instead.

Tips and tricks

Alacritty Install

Spawn new instance in same directory

Add the following lines to your configuration file to spawn a new instance of Alacritty in the current working directory by pressing Ctrl+Shift+Enter:

'user@host:cwd' in window title bar

The window title bar shows 'Alacritty' unlike other terminal emulators under Arch, which by default show 'user@host:cwd'. See FS#70752.

If you want the Arch default behavior to apply to all your users in Alacritty, you need to edit your /etc/bash.bashrc file.

Find the case statements which sets the $PROMPT_COMMAND for other terminals:

Then edit the line xterm*|rxvt*|Eterm|aterm|kterm|gnome*) to add alacritty* so that it reads xterm*|rxvt*|Eterm|alacritty*|aterm|kterm|gnome*).

Vi mode and copy/paste

The vi mode allows moving around Alacritty's viewport and scrollback using the keyboard. By default you can toggle it using Ctrl+Shift+Space. To copy, you can either use a mouse to select and press Ctrl+Shift+c, or enter Vi mode, start a selection using v, move around with hjkl like in vim, and copy the selection with y. To paste, press Ctrl+Shift+v. To copy/paste to/from X clipboard, you can use a mouse selection to copy and a middle mouse click to paste.

Troubleshooting

Mouse not working properly in Vim

Add ttymouse=sgr to your .vimrc or switch to Neovim. Also see this issue.

Transparent border in dwm

With dwm, alacritty's borders become transparent. Adding this line to drw.c in the dwm source directory and recompiling fixes the issue:

Terminal functionality unavailable in remote shells

When connecting to a remote system from an Alacritty terminal, for instance over SSH, it can occur that the system does not have an entry for Alacritty in its terminfo database (/usr/share/terminfo/a/alacritty*). Therefore, all interactive terminal functionality does not work. This can be fixed by copying the terminfo for Alacritty to the remote server, as described in termite#Terminal issues with SSH.

On the local host, using Alacritty:

On the remote host, in the directory where you copied alacritty.terminfo:

Alternatively, one can set the value of TERM in the configuration to xterm-256color instead of the default alacritty:

Requires hardware supporting GLSL 3.30

Install Alacritty On Mac

You can force Alacritty to use software rendering by launching it with the environment variableLIBGL_ALWAYS_SOFTWARE=1[1]:

No title bar on Wayland GNOME

Install Alacrity Terminal For Macos Catalina

When using Wayland GNOME the title bar could be empty and with strange icons [2].

The workaround is to launch Alacritty with an empty WAYLAND_DISPLAYenvironment variable:

It is also possible to replace the two Exec lines in /usr/share/applications/Alacritty.desktop with this:

Different font size on multiple monitors

By default, Alacritty attempts to scale fonts to the appropriate point size on each monitor based on the Device pixel ratio. On some setups with multiple displays, this behavior can result in vastly different physical sizes [3], [4].

Alacritty Macos

To view the existing device pixel ratio values for each monitor, run alacritty -v, move the child window to each monitor, and pay attention to the reported Device pixel ratio in the parent window.

Forcing a constant device pixel ratio using the WINIT_X11_SCALE_FACTOR environment variable may be sufficient to fix the different font size issue:
