Alacritty

Alacritty terminal emulator focused on simplicity and performance.]] The performance goal means it should be faster than any other terminal emulators available. The simplicity goal means it doesn't have features such as tabs or splits (which can be better provided by a window manager).

Alacritty is written in Rust and GPU-accelerated using OpenGL.

Install package:

Files
Following paths are searched for configuration:



If no configuration is found then is created on the first run. On most systems this path defaults to:.

The default configuration file get installed into directory.

Many configuration options will take effect immediately upon saving the config file. Exception are the  and   sections which requires Alacritty to be restarted.

For detailed explanation of the config file, please consult the comments in the default config file.

Choosing a font
Since Alacritty is configured by editing a configure file by hand, users can't just choose a font from a submenu. This might cause some problems since one needs to supply the exact font name for Alacritty.

To make things easier users can run following command and just copy and paste the desired font name:

Since Alacritty configuration auto load feature doesn't work when changing font, users can try out different fonts easily by starting alacritty from a terminal by issuing following command:

That would start alacritty with size 12 "DEC Terminal" as font.

Font is too small or big
Status of this caveat can be tracked under: Issue #1501.

... are weird
By default alacritty has not the font colors users would normally expect. Users need to configure Alacritty's color settings to the desired effect.

Here's a good starting point which some users may find sufficient:

Prompt ($PS1) is colorless and $LS_COLORS is unset
This is an issue with.

Since at least in bash shell the default checks the terminal color capability by running, users may add   -line into  -file into a place where all other TERM lines reside at the beginning of the file. This assumes user hasn't done any significant changes to the -file prior to this change. However, a bug report has been submitted. So in future alacritty might be included in by default.
