Hello, everybody! I am new here. I am also relatively new to ruby.

I don't know if it's OK to ask questions here before the 48 hours
period ends. So I am going to shoot straight and ask.

I am trying to create a perfect regexp match string to match an array
string like [1, -1, 4, 5]
So far the best I've came up with is /^\[-*\d+,*.*\]$/

If I add \s+ the string doesn't match. /^\[-*\d+,*\s+.*\]$/ And I have
no idea why...
