Overview

Generate Phlex icons from Lucide icons

  1. Download the Lucide icons

  2. Convert the SVG icons to Phlex icons using Phlexing

  3. Generate the Phlex icon classes

  4. Update the auto-gen code in lib/phlex/lucide.rb to autoload the new icons

  5. Run Rubocop to format the generated files

  6. Be happy :)
