to_request_set(development = :none) click to toggle source

Converts this AvailableSet into a RequestSet that can be used to install gems.

If development is :none then no development dependencies are installed. Other options are :shallow for only direct development dependencies of the gems in this set or :all for all development dependencies.

# File lib/rubygems/available_set.rb, line 105
def to_request_set development = :none
 request_set = Gem::RequestSet.new
 request_set.development = :all == development

 request_set.gem spec.name, spec.version
 request_set.import spec.development_dependencies if
 :shallow == development
 end
