trollop
1.8.2
DESCRIPTION Trollop is a commandline option parser for Ruby that just gets out of your way. One line of code per option is all you need to write. For that, you get a nice automatically-generated help page, robust option parsing, command subcompletion, and sensible defaults for everything you don’t specify. #################### ###### simple ###### #################### require ‘trollop’ opts = Trollop::options do opt :monkey, "Use monkey mode" opt :goat, "Use goat mode", :default => true opt :num_limbs, "Set number of limbs", :default => 4 end p opts # { :monkey => false, :goat => true, :num_limbs => 4 } #################### ###### medium ###### #################### require ‘trollop’ opts = Trollop::options do version "test 1.2.3 © 2007 William Morgan" banner <<-EOS Test is an awesome program that does something very, very important. Usage: test [options] <filenames>+ where [options] are: EOS opt :ignore, "Ignore incorrect values" opt :file, "Extra data filename to read in, with a very long option description like this one", :type => String opt :volume, "Volume level", :default => 3.0 opt :iters, "Number of iterations", :default => 5 end Trollop::die :volume, "must be non-negative" if
opts
< 0 Trollop::die :file, "must exist" unless
File.exist?(opts
) if
opts
################################ ##### sub-command support ###### ################################ require ‘trollop’ global_opts = Trollop::options do opt :global_option, "This is a global option" stop_on %w(sub-command-1 sub-command-2) end cmd = ARGV.shift cmd_opts = Trollop::options do opt :cmd_option, "This is an option only for the subcommand" end p global_opts p cmd p cmd_opts
