Checks whether it uses the version helper or the users defined version.

prettyify_array(gemspec_ruby, array_name) click to toggle source

Adds extra space when outputting an array. This helps create better version control diffs, because otherwise it is all on the same line.

# File lib/jeweler/gemspec_helper.rb, line 66
def prettyify_array(gemspec_ruby, array_name)
  gemspec_ruby.gsub(/s\.#{array_name.to_s} = \[.+?\]/) do |match|
    leadin, files = match[0..-2].split('[')

    leadin + "[\n    #{files.gsub(%(", "), %(",\n    "))}\n  ]"
