rx = Regexp.new [’^([\w,]+)’, \*["’(.+?)’"]\*3].join(’, ')

😉

(assuming ‘\_’ in the first field is acceptable)

Beautiful! Or wait, did I mean beautiful? Maybe I meant sick and wrong.

But you know what, just to taunt you Perlish types…

The initial regex I posted was actually wrong.

It was this:

when /^([A-Za-z0-9,]+), ‘([^’]+)’, ‘([^’]+)’, ‘([^’]+)’/

It needed to be this instead:

when /^([A-Za-z0-9,]+), ‘([^’]+)’, ‘([^’]+)’, ‘([^’]\*)’/

Bet you can’t DRY that!

I meant make

## DRYER, all that needless repetition of the digit 1!
