Re: GetoptLong Accessing the values with out looping


#1

Makes perfect sense in this example you are still looping
through the options. All though this is better on the eyes.

I was hoping that the instance of getoptlong had some kind of
method to get the value of one of the command line options.

Yes, it sucks. That’s why I wrote the ‘getopt’ package.

gem install getopt :slight_smile:

require ‘getopt/long’
include Getopt

opts = Getopt::Long.new([’-d’, ‘–date’, REQUIRED])

if opts[‘d’]

end

nice dan. i’ve been using optparse for all my stuff but it’s usage is a
bit
obtuse. perhaps i’ll switch… does it support parsing arbitrary arrays
or
only ARGV?

I am having an issue with the script working. Is their some path
variable
that needs to be set for ruby to see the gem packages?

Initially i have the ubuntu ruby pkgs installed. I have removed them and
built ruby 1.8.4 and gems 0.8.11 built from source.

Any ideas?
