A very simple option parser.
It uses as inspiration Git's internal option parser code, and Ruby's OptionParser.
require 'parseopt'
opts = ParseOpt.new('my command')
# only short
opts.on('b') do |v|
$bool = v
end
# short and long
opts.on('s', 'string') do |v|
$string = v
end
# short, long, and help
opts.on('n', 'number', 'Number') do |v|
$number = v.to_i
end
opts.parseRunning with --help gives:
usage: my command
-b
-s, --string
-n, --number Number
