Courses Plus Student 586 PointsSplit One Argument Into Multiple?
Is there a way to take one argument (lets say an output from a .read) and split it into multiple arguments?

19,286 PointsI've found that the ruby "split" function has been useful.
Below are some examples from irb. Split defaults to splitting on spaces, but it will also accept another character like ",". And it will also take a regular expressions (yes they implement the dark side of the force) The last example's regular expression /,\s|,|\s/ says to split on 1) comma followed by a space or 2) a comma or 3) a space.
irb(main):001:0> "abc 123 xy".split => ["abc", "123", "xy"]
irb(main):002:0> "abc,123,xyz".split(",") => ["abc", "123", "xyz"]
irb(main):008:0> "abc, 123, xyz".split(/,\s|,|\s/) => ["abc", "123", "xyz"]

Courses Plus Student 586 PointsAwesome, thanks. I haven't done much with regular expressions but seems like a good time to learn! Thanks so much!
