Alacritty Color Export

A temporary, Regex based solution to export generated (Wal) colors into Alacritty config with one command.

Tested on macOS (10.14.6, 10.15.2, 11.2.1) with Alacritty (0.3.3, 0.4.2-dev, 0.6.0) and works as intended. Sed commands may differ on untested distros and give errors.

Initial Purpose

Currently there's no easy way to send wal colors to alacritty config in Mac. So I created this script to automatically update colors as a temporary solution.

Installation

Deps: grep, sed

You can simply go to raw file and save the file to your script directory or open your terminal emulator:

git clone https://github.com/egeesin/alacritty-color-export
cd alacritty-color-export
chmod +x script.sh

Usage

Before executing the script, comment existing color declarations out in order to avoid duplication errors and keep your initial colors. Also to get colors, you must have run wal -i <image.png> (or wal -ni <image.png> if you on Mac) once. If you already did, then...

# Execute
./script.sh

# Execute with custom config
./script.sh <config.yml>

Example

Terminal emulator:

$ ./script.sh

Input (~/.cache/wal/colors.sh):

...
color0='#0a0c0a'
color1='#514739'
color2='#6B4F39'
color3='#776338'
color4='#5E5747'
color5='#936843'
color6='#75936F'
color7='#d6c6a6'
color8='#958a74'
color9='#514739'
color10='#6B4F39'
color11='#776338'
color12='#5E5747'
color13='#936843'
color14='#75936F'
color15='#d6c6a6'
...

Output (~/.config/alacritty/alacritty.yml):

...
# BEGIN ACE

    background: '#0a0c0a'

# END ACE

Known Issues

~~If there isn't # BEGIN ACE comment, the script wipes out whole config.~~

Roadmap

Fix critical issues
Make use of config import
- Remove necessity of surrounding comments for not corrupt config
Handle indented lines instead of repeated group names
Option to disable cursor and selection colors
Add subcommands to define input (colors) and output (Alacritty config) path
Support for different default config path for different OS
An option to clean all possible duplicate color declarations and generate new ones

Contribution

Don't forget to backup config and thank you for your contribution in advance. Any information from testing on different systems would valuable to anyone who interested in this script. Issues and PR's are welcomed.
