Subject: Re: Regexp captures

On Behalf Of El Gato:
# (c = result.match(/id: (\d+)/)) ? c.captures.first : 
# result.scan(/error: (.*)/).to_s

why not just build the regex and then capture/match.

irb(main):067:0> re = /(id|error): ((\d+)|(.*))/
=> /(id|error): ((\d+)|(.*))/
irb(main):068:0> result = "id: 1234"
=> "id: 1234"
irb(main):069:0> c = result.match(re)[2].to_s
=> "1234"
irb(main):070:0> result = "error: this is an error"
=> "error: this is an error"
irb(main):071:0> c = result.match(re)[2].to_s
=> "this is an error"
