Little script to generate composer.json files for all modules/themes/profiles from root Drupal directory.

README.md

Usage

• Copy script and template from this repo into root of 8.x branch of Drupal repo.
• Run ruby -e "require './generate-composer-json-files.rb'; generate_composer_files"

TODO

• Add ability to generate composer.json for Drupal components.
• Add script to split out repos with git subtree split and push to github.
• Add script to edit Drupal core's composer.json to pull in projects.
