options. All though this is better on the eyes.

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?
regards.

Just ARGV, I’m afraid. I suppose you could push args onto ARGV directly
as a workaround.
May I ask when you would want to parse an arbitrary array? I’m curious.
Oh, and when I said, “Yes, it sucks”, I was referring to getoptlong in
the stdlib, not your code in particular. Just thought I should clarify
that. 
Regards,
Dan

most of my standalone production code looks like this
~ > cat foo
module Foo
class Main
…
end
end
Foo::Main.run(ARGV, ENV) if FILE == $0
that way foo runs as a script. however the code can be re-used in this
way
too
~ > cat bar
require ‘foo’
module Bar
class Main < Foo::Main
argv << ‘–foo-option=42’
env[‘foo_env’] = 42
super(argv, env)
end
end
Bar::Main.run(ARGV, ENV) if FILE == $0
or
foo = Foo::Main.new ‘–key=val --k2-v2’
etc.
basically i re-use top-level code as libs sometimes and then it’s
important
that two bits of code aren’t fighting over ARGV/ENV.

either way - no offense taken!
cheers.

Easier to write unit tests for, maybe.
