Really Cheap Command-Line Option Parsing in Ruby

Answer 1

I totally understand why you want to avoid optparse - it can get too much. But there are a few far "lighter" solutions (compared to OptParse) that come as libraries but are simple enough to make a single gem installation worthwhile.

For example, check out this OptiFlag example. Just a few lines for the processing. A slightly truncated example tailored to your case:

require 'optiflag'

module Whatever extend OptiFlagSet
  flag "f"
  and_process!
end 

ARGV.flags.f # => .. whatever ..

There are tons of customized examples too. I recall using another that was even easier, but it has escaped me for now but I will come back and add a comment here if I find it.
