regex help please?

[Joe Pizzanley]

I've looked at regular expression documentation for hours, but I'm
wondering if someone would have pity on me and just slip me the answer.
What I want to do is get each of the item numbers on a list:

onscreen:
pens 1234-001
pencils 1234-002
scissors 2345-447

I'm thinking the numbers would go into an array... I'd be happy with any
ideas.


much thanks!!
Joe

You mean, like this?

irb(main):001:0> str =<<STR
irb(main):002:0" pens 1234-001
irb(main):003:0" pencils 1234-002
irb(main):004:0" scissors 2345-447
irb(main):005:0" STR
=> " pens 1234-001\n pencils 1234-002\n
scissors 2345-447\n"
irb(main):006:0> str.scan(/(?:\d|\-)+/)
=> ["1234-001", "1234-002", "2345-447"]
irb(main):007:0>

Vale,
Marvin

sometimes I end up with 2 of the same thing, how would I remove the
duplicate?

irb> ["a", "b", "c", "a", "d", "c"].uniq
=> ["a", "b", "c", "d"]
