Summary: trollop 1.0
Project: Trollop

trollop version 1.0 has been released!

Trollop is YAFCLAP --- yet another fine commandline argument
processing library for Ruby. Trollop is designed to provide the
maximal amount of GNU-style argument processing in the minimum number
of lines of code (for you, the programmer).

Trollop provides a nice automatically-generated help page, robust
option parsing, and sensible defaults for everything you don't
specify.

Synopsis:

###### simple ######

opts = Trollop::options do
opt :monkey, "Use monkey mode."
opt :goat, "Use goat model", :default => true
opt :num_limbs, "Set number of limbs", :default => 4
end

p opts

###### complex ######

opts = Trollop::options do
version "test 1.2.3 (c) 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[:volume] < 0
Trollop::die :file, "must exist" unless File.exists?(opts[:file]) if opts[:file]

* none
