Trollop version 1.0 has been released!

[http://trollop.rubyforge.org](http://trollop.rubyforge.org)

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.”  
banner \<\<-EOS  
Test is an awesome program that does something very, very important.

Usage:  
test [options] +  
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
