Regex to match comma followed by whitespace?

I am trying to make a ruby regex t开发者_StackOverflow中文版o match tags in the format Toys, Cars, Some Other Topic but I can't figure out how to make it so that it splits it at after a comma and white space after but not if there is whitespace in a tag

This is what I have come up with http://rubular.com/r/ptjeQ1KyoD but is wrong for now.

/[\/,$\(\s+)]/

You can just use /,\s*/ (which is much simpler than what you've got!):

'Toys, Cars, Some Other Topic'.split /,\s*/
=> ["Toys", "Cars", "Some Other Topic"]

You should just use:

,\s+

This matches all commas followed by one or more whitespace characters, and doesn't match the spaces beyond Some.

---

You could use (/,/x) which split all strings with comma(,)

Check here

'Toys, Cars, Some Other Topic'.split(/,/x)
=> ["Toys", "Cars", "Some Other Topic"]
