Question

I am curious, is there a faster/better way to parse hashtags in a string, other than using Regular Expressions (mainly in Ruby)?

Edit
For example I want to parse the string This is a #hashtag, and this is #another one! and get the words #hashtag and #another. I am using #\S+ for my regex.

Answer 1

You don’t show any code (which you should have) so we’re guessing how you are using your regex.

#\S+ is as good of a pattern as you’ll need, but scan is probably the best way to retrieve all occurrences in the string.

'This is a #hashtag, and this is #another one!'.scan(/#\S+/)
=> ["#hashtag,", "#another"]

Its should be /\B#\w+/, if you don’t want to parse commas

Yes, I agree. /\B#\w+/ makes more sense.
