Welcome to Gem Session 🤘

⚡ Where code meets heavy metal. ⚡

This app is a side gig for me to learn Ruby & Rails.

The idea is simple:

• The app randomly selects three Ruby gems (see below)
• An LLM proposes a project prompt for the user to build using two matching gems
• Users can follow, like, etc. each other's work
• Add lots of tropes, puns and inside jokes about music and coding

Design considerations

Randomized Gem selection

Not all gems are useful and/or appropriate for a coding challenge.

The app will only select Gems which (according to RubyGems.org) have:

• at least ten versions since 2020
• between 10,000 and 1,000,000 total downloads
• a description and a (working) homepage link

At first, I thought I'd add a minimum length for the Gems' description. Then I noticed that even very common ones usually have very short descriptions on RubyGems.org. Hence the requirement for a homepage link, which the LLM visits when generating the project prompt.

Gem seeding pipeline

To seed the Rubygem model, you'll need to:

1. Check out the rubygems/rubygems.org repo
2. Download and import a database dump
3. Run script/dump_gemmables.rb > all-gemmables.yml
4. Run script/filter_broken_urls all-gemmables.yml db/gemmables.yml
5. Run rails db:seed
