Ruby idiom for all matches in a string

[David Corbin]

What's the ruby idiom for all the matches in a string.

x="ABA ABBBA CBBA"
/A(B+)/.match(x)

Ultimately, I want to get [ "B", "BBB" ]

Thanks

With only one grouping expression you can do:

x.scan(/A(B+)/).flatten

In case the first part would be more complex you can still use non
grouping brackets:

x.scan(/(?:A)(B+)/).flatten

x.scan(/(?:A)(B+)/).flatten

Or you do an additional select step:

x.scan(/(A)(B+)/).map {|m| m[1]}
