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 M.”

opt :iters, “Number of iterations”, :default => 5
