Pycritty

Change your alacritty config on the fly!

Installation:

pip install pycritty

By default, only the program itself will be installed, but you can install default themes from config/themes:

pip install --install-option="--themes=onedark,dracula,nord" pycritty

Or if you want them all:

pip install --install-option="--themes=all" pycritty

Make sure to have ~/.local/bin directory in your $PATH, otherwise your shell won't find the pycritty command. Add this line to your ~/.xprofile if you haven't already:

export PATH=$HOME/.local/bin:$PATH

Also if you are an Arch user you can install from the AUR (only the program will be installed)

git clone https://aur.archlinux.org/pycritty.git
cd pycritty
makepkg -si

Or with an AUR helper like yay

yay -S pycritty

Usage:

Change your current config:

pycritty --font UbuntuMono --font-size 14 --opacity 0.95 --padding 3 3

Save multiple configs and reuse them later:

pycritty save ThisConfig
pycritty load AnotherConfig

Install themes and configs from URLs:

pycritty install --theme https://raw.githubusercontent.com/antoniosarosi/pycritty/master/config/themes/breeze.yaml
pycritty --theme breeze # Apply downloaded theme
pycritty install --config --name SomeCoolConfig https://raw.githubusercontent.com/antoniosarosi/dotfiles/master/.config/alacritty/config.yaml
pycritty load SomeCoolConfig # Apply downloaded config

Check help for all available options:

pycritty -h
# pycritty subcomand -h
pycritty save -h

Fonts Config

Fonts are configured at ~/.config/alacritty/fonts.yaml with this format:

fonts:
    Alias: Font Name

When applied using pycritty -f Alias, the previous format will be converted into the alacritty equivalent:

font:
    normal:
        family: Font Name
    italic:
        family: Font Name
    bold:
        family: Font Name

You can also specify a different font for each font type:

fonts:
    Alias:
        normal: Normal Font Name
        bold: Bold Font Name
        italic: Italic Font Name

Note that the fonts must be installed on your system.

Theme Config

You can make your own custom themes by creating new theme files with the correct format, ~/.config/alacritty/themes/custom.yaml should look like this:

colors:
    # Default colors
    primary:
        background: '0x292d3e'
        foreground: '0xbbc5ff'
    # Normal colors
    normal:
        black:   '0x101010'
        red:     '0xf07178'
        green:   '0xc3e88d'
        yellow:  '0xffcb6b'
        blue:    '0x82aaff'
        magenta: '0xc792ea'
        cyan:    '0x89ddff'
        white:   '0xd0d0d0'
    # Bright colors
    bright:
        black:   '0x434758'
        red:     '0xff8b92'
        green:   '0xddffa7'
        yellow:  '0xffe585'
        blue:    '0x9cc4ff'
        magenta: '0xe1acff'
        cyan:    '0xa3f7ff'
        white:   '0xffffff'

Then you can apply it using the name of the file:

pycritty -t custom

Custom scripts

If you want to apply different configs programmatically, you can either use the CLI in a shell script or use pycritty as a python module:

#!/bin/python3

# Dummy script that changes the theme every 5 minutes

import time
import pycritty


def main():
    config = pycritty.Config()
    while True:
        for theme in pycritty.list_themes():
            config.change_theme(theme)  # or config.set(theme=theme)
            config.apply()
            time.sleep(300)


if __name__ == '__main__':
    main()

Shell equivalent:

#!/bin/bash

while :; do
    # Same as pycritty ls --themes --iterable
    for theme in $(pycritty ls -ti); do
        pycritty -t $theme
        sleep 300
    done
done
