How do I extract strings from a string?

Question

I have a long string, consisting of multiple sentences, of various length, divided by a "-".

I want to iterate over the string and extract everything between the -'s, preferably to an array.

From another thread I found something that gets me pretty close, but not all the way:

longString.scan( /-([^-]*)-/)

Needless to say, I am new to Ruby, and especially to RegEx.

Answer 1

What's wrong with using String#split?

longString.split('-')

Answer 2

Why not just use string.split()?

longString.split('-');
