Hi, I usually do Ruby scripts for some tasks and many of them allow  
inline  
parameters, for example:

./script1.rb -n -vv -o file.out filein

Is there any Ruby library/gem to parse inline parameters easily? this  
is,  
parsing ARGV Array.

Thanks.

There’s OptionParser which is included in ruby standard library. Use ri  
OptionParser to learn more about it (you need to require ‘optparse’  
before you  
can use it)

You can also try “getoptlog” library.
