Code Along

1. Create the gem skeleton

   bundle gem topreddit
   

2. CD into the gem

   cd topreddit
   

3. Alter the gemspec to add anything you'd normally put in the Gemfile

   vi topreddit.gemspec
   

   Note: You can add runtime dependencies with spec.add_runtime_dependency

4. Add the fluff of your gem to lib/topreddit.rb or require the appropriate other files from lib/topreddit/

   vi lib/topreddit.rb
   

5. Make your gem executable, add any instantiation options here

   vi bin/topreddit
   chmod +x bin/topreddit
   

   Note: You'll need to require the main file in lib

6. Add the files in git

   git add .
   git commit -m "Initial commit"
   

7. Build your gem locally

   gem build topreddit.gemspec
   

8. Install your gem locally

   gem install ./topreddit-0.0.1.gem
   

9. Deploy to rubygems

   gem push topreddit-0.0.1.gem
