An excellent quick resource for Ruby can be found here :

http://www.zenspider.com/Languages/Ruby/QuickRef.html

The use of % constructs is covered in the types section (in the strings,
arrays and regexen).

Your latter question about // is also covered - those are regular
expressions.  A very quick reference is also included.

BTW, the best way to learn ruby itself (without rails) is to log on a
machine where it is installed and launch the irb console program.  It
allows you to test snippets of code interactively :

15:41 fred@grappa:~> irb
>> %w(a b c d e f)
=> ["a", "b", "c", "d", "e", "f"]
>> %w(a b c d e f).is_a? Array
=> true

(What I type is after the >> prompt, the => is the response, i.e. what
the expression evaluates to.)

G'd luck and enjoy !
