“Command” Gem

This is helper for creating multi-command apps (like Git, for example).

Provides the Is::Command class.

Usage example

Application

require 'is/command'

app = Is::Command::Application.new do

  key '-h', '--help' do
    puts "#{$0} -h|--help|<command> <files>"
    puts "\t-h, --help -- Show this help."
    puts "\taccess <files> -- Show access time for files."
    puts "\tcreate <files> -- Show creation time."
    puts "\tmodify <files> -- Show modification time."
    halt 0
  end

  action :access do |*args|
    args.each do |filename|
      puts "#{filename} => #{File.atime(filename)}"
    end
  end

  action :create do |*args|
    args.each do |filename|
      puts "#{filename} => #{File.ctime(filename)}"
    end
  end

  action :modify do |*args|
    args.each do |filename|
      puts "#{filename} => #{File.mtime(filename)}"
    end
  end

  default do
    $stderr.puts 'Command not found.'
    halt 1
  end

end

app.run    # <=> app.process *ARGV

One-block application

require 'is/command'

Is::Command.runapp do

  # ... key definitions like above

  # ... action definitions...

end

Other object wrap

require 'is/command'

obj = Object.new
obj.instance_eval do

  include Is::Command::Mixin    # sic!

  # ... key definitions like above

  # ... action definitions...

end
obj.process *ARGV

Global object mixed

require 'is/command'

include Is::Command::Mixin

# ... key definitions like above
