Overview
A semi-compatible DSL for the Bundler Gemfile and Isolate gem dependencies files.
To work with both the Bundler Gemfile and Isolate formats this implementation takes some liberties to allow compatibility with each, most notably in #source.
A basic gem dependencies file will look like the following:
source 'https://rubygems.org'
gem 'rails', '3.2.14a
gem 'devise', '~> 2.1', '>= 2.1.3'
gem 'cancan'
gem 'airbrake'
gem 'pg'
RubyGems recommends saving this as gem.deps.rb over Gemfile or Isolate.
To install the gems in this Gemfile use gem install -g
to install it and create a lockfile. The lockfile will ensure that when you make changes to your gem dependencies file a minimum amount of change is made to the dependencies of your gems.
RubyGems can activate all the gems in your dependencies file at startup using the RUBYGEMS_GEMDEPS environment variable or through Gem.use_gemdeps. See Gem.use_gemdeps for details and warnings.
See gem help install
and gem help gem_dependencies
for further details.

. You may also supply options
following the requirements
options
include:

RubyGems does not provide any autorequire features so requires in a gem dependencies file are recorded but ignored.
In bundler the require: option overrides the file to require during Bundler.require. By default the name of the dependency is required in Bundler. A single file or an Array of files may be given.
To disable requiring any file give
false
:gem 'rake', require: false

Place the dependencies in the given dependency group. A single group or an Array of groups may be given.

See #platform for a list of platforms available.
- path:
-

- github:
-
Install this dependency from a github git repository:
gem 'private_gem', github: 'my_company/private_gem'
- submodules:

NOTE: There is inconsistency in what environment a platform matches. You may need to read the source to know the exact details.
#platforms(*platforms)
Block form for restricting gems to a particular set of platforms. See #platform.
# File 'lib/rubygems/request_set/gem_dependency_api.rb', line 772
alias :platforms :platform
#ruby(version, options = {})
Restricts this gem dependencies file to the given ruby version
.
You may also provide engine:
and engine_version:
options to restrict this gem dependencies file to a particular ruby engine and its engine version. This matching is performed by using the RUBY_ENGINE and engine_specific VERSION constants. (For JRuby, JRUBY_VERSION).
# File 'lib/rubygems/request_set/gem_dependency_api.rb', line 784

#source(url)
Sets url
as a source for gems for this dependency API. RubyGems uses the default configured sources if no source was given. If a source is set only that source is used.
This method differs in behavior from Bundler:
-
The
:gemcutter
, #:rubygems
and:rubyforge
sources are not supported as they are deprecated in bundler. -
The
prepend:
option is not supported. If you wish to order sources then list them in your preferred order.
