Dahlia.sh

Dahlia is a simple text formatting package, inspired by text formatting in the game Minecraft.

Text is formatted similarly to the game. With Dahlia, it is formatted by typing a special character & followed by a format code and finally the text to be formatted.

Installation

Download the source and put the dahlia executable in your $PATH.

Dependencies

The scripts are written for GNU Bash 5.0/ZSH 5.9 and newer.

Other dependencies are reasonably modern (if someone knows how to find the minimal required version, please let me know).:

• GNU grep and sed (non GNU version probably work too but aren't officially supported)
• GNU coreutils - dirname, sort, uniq

Note: It is expected that all those commands are available in the $PATH.
