A QUICK INTRO RubyGems

I’m a Senior Systems Architect at Athega (where I build stuff in Ruby) ⃔ I’m also the owner o Code7 Interactive (where I build stuff in Ruby) ⃕ 

Gem::Specification.new do |s| # The attributes end Gem Speci ication In order to create a gem, you need to define a gem specification, commonly called a “gemspec”. 

Required gemspec attributes name This gem’s name summary A short summary of this gem’s description. Displayed in `gem list -d`. version This gem’s version s.required_ruby_version = ">= 1.8.7" Required Ruby Version 

Name, Summary and Version s.name = "pinch" s.summary = "Retrieve a file from" + "inside a zip file, over" + "the network!" s.version = Pinch::VERSION I generally add a ProjectName::VERSION constant to all of my projects, this makes it easy to show the current version at runtime. 

s.email = "[email protected]" s.homepage = "http://peterhellberg.github.com/pinch/" s.authors = ["Peter Hellberg", "Edward Patel"] s.license = "MIT-LICENSE" About 

s.files = Dir.glob("lib/**/*") + %w(MIT-LICENSE README.rdoc Rakefile .gemtest) Files s.test_file = "spec/pinch_spec.rb" Testing 

s.has_rdoc = true s.rdoc_options = [ '--main', 'README.rdoc', '--charset=UTF-8' ] s.extra_rdoc_files = [ 'README.rdoc', 'MIT-LICENSE' ] Documentation 

s.add_development_dependency 'yard', '~> 0.7' s.add_development_dependency 'minitest','~> 2.8' s.add_development_dependency 'fakeweb', '~> 1.3' s.add_development_dependency 'vcr', '~> 1.11' Dependencies No runtime dependencies in this particular project, otherwise I’d need a few calls to s.add_dependency
