Like NewGem, but way simpler, leaves no traces, extremely minimal boiler plate. Automatically handles extensions for Rack, Yard, Sinatra, etc correctly.

Like NewGem, but way simpler, leaves no traces, extremely minimal boiler plate. Automatically handles extensions for Rack, Yard, Sinatra, etc correctly.

Inspired by Steve Klabnik's Making Ruby Gems.

Only point where it is opinionated: It sets up RSpec. But all you have to do if you don't like that, is changing a single line in the generated Rakefile.

Feel free to contribute.

Usage

gemerate GEM_NAME

Simpe example:

$ gemerate foo
...
$ tree foo
foo
├── Gemfile
├── License
├── README.md
├── Rakefile
├── foo.gemspec
├── lib
│   ├── foo
│   │   └── version.rb
│   └── foo.rb
└── spec
    └── foo_spec.rb

3 directories, 8 files

For an extension:

$ gemerate rack-foo
...
$ tree rack-foo/
rack-foo/
├── Gemfile
├── License
├── README.md
├── Rakefile
├── lib
│   ├── rack
│   │   ├── foo
│   │   │   └── version.rb
│   │   └── foo.rb
│   └── rack-foo.rb
├── rack-foo.gemspec
└── spec
    └── rack_foo_spec.rb

4 directories, 9 files

Per default, rack-foo.gemspec will automatically depend on rack and lib/rack/foo.rb will require rack.

Why not bundle gem?

bundle gem is fine, but just too little boilerplate, here is what is different:

  • A rake test is ready to go.
  • The gemspec does not include shell-outs, file list is not generic (this is a feature!)
  • Less TODOs all over the place you have to remove
  • No rubbish in the .gitignore
  • Includes rake task to update files/authors/e-mails from git and version from lib (similar to what Sinatra/Tilt/sinatra-contrib and so on do)
  • Internally, the version is not a string to avoid alphanumerical comparison (similar to what Rails does)
  • You can do QUICK=1 bundle install to avoid fetching from RubyForge
  • Some logic to generate better boilerplate for extensions (Rack middleware, Sinatra extensions, ...) has been added.

Apart from that, it's pretty much the same. Oh, wait, and it works without bundler.
