A simple little script I use to keep the readme for my local podspecs up to date.

generate_readme.rb

#!/usr/bin/env ruby

puts ''
puts 'Generating README...'

readme = ''

specs = Dir.glob('./*').select { |fn| File.directory?(fn) }

summaryRegEx = /\s*s.summary\s*=\s*\"(.*)\"/
dependencyRegEx = /\s*s.dependency\s*'(\w*)',\s*'(.*)'/

entryCount = 0

specs.each do |specFolder|
  entryCount = entryCount + 1

  versions = Dir.glob(specFolder + '/*').select { |fn| File.directory?(fn) }
  version = versions[-1]
  
  frameworkName = version.split('/')[-2]
  frameworkVersion = version.split('/')[-1]

  readme += "## " + frameworkName + " (" + frameworkVersion + ")\n"
  
  specFiles = Dir.glob(version + '/*').select { |fn| !File.directory?(fn) }

  specFiles.each do |file|
    contents = File.open(file).read
    summary = contents.match(summaryRegEx)

    if summary
      readme += "\n" + summary[1] + "\n"
    end

    dependencies = contents.scan(dependencyRegEx)

    if dependencies.count > 0
        readme += "\n#### Depends on\n" 

        dependencies.each do |dependencyMatch|
            readme += "\n - " + dependencyMatch[0] + " " + dependencyMatch[1] + "\n"
        end
    end

    readme += "\n\n"

  end
end

File.open("README.md", 'w') { |file| file.write(readme) }

puts entryCount.to_s + ' entries written to README.md.'
