geminstaller_builder

A simple tool for generating valid and up-to-date geminstaller files. Bundler is probably what you want, but if you're supporting legacy apps or you just like geminstaller, this could be helpful.

Use

Solo

require 'geminstaller_builder'
geminstaller = GeminstallerBuilder.new
geminstaller.add 'haml'
geminstaller.add 'state_machine'
geminstaller.add 'shoulda', :test
geminstaller.save

Will create two files:

config/geminstaller.yml:

---
defaults:
  install-options: '--no-rdoc --no-ri'
gems:
- name: haml
  version: '= 2.2.22'
- name: state_machine
  version: '= 0.8.1'

config/test/geminstaller.yml:

---
defaults:
  install-options: '--no-rdoc --no-ri'
gems:
- name: shoulda
  version: '= 2.10.3'

relative to the directory from which the script was run.

By default, the :default and :test environments are assumed. To change the names of the files generated, pass in a :paths option with the full filenames. For example:

require 'geminstaller_builder'
geminstaller = GeminstallerBuilder.new :paths => {:default => 'geminstaller.yml', :test => 'geminstaller-test.yml'}
geminstaller.add 'haml'
geminstaller.add 'state_machine'
geminstaller.add 'shoulda', :test
geminstaller.save

will create geminstaller.yml and geminstaller-test.yml.

In a Rails application template

Looks pretty much the same. I use it like this:

template.rb:

# use geminstaller instead of gem
require 'geminstaller_builder'
@geminstaller = GeminstallerFile.new
def geminstaller s, env=:default
  @geminstaller.add s, env
end

# later on ...
geminstaller 'will_paginate'
geminstaller 'hpricot'
geminstaller 'json'
geminstaller 'state_machine'
geminstaller 'paperclip'

load_template 'http://github.com/smartlogic/rails-templates/raw/master/test.rb'

and in test.rb:

geminstaller 'factory_girl', :test
geminstaller 'shoulda', :test
geminstaller 'redgreen', :test
geminstaller 'timecop', :test
geminstaller 'hydra', :test
geminstaller 'mocha', :test

# etc...

Finally, at the end of template.rb, I have:

@geminstaller.save

at which point, geminstaller_build consults the currently available gems to build the appropriate geminstaller.yml files.

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally. But then, I haven't included any tests. So do what feels good.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
