What are those %{} things in ruby?

[xmitchx]

Hi,

In my quest to learn Ruby a few months ago I never did learn what the code that looks like this is:
%w{bla bla2 bla3}

What are those? What letters are available for after the %? What do they do?

Thank you,
Mitch

It's a Perl-style quick array. That's the way I think of them at least, there's probably a more accurate description.

Do you know of a place where I can read more about them?

I'm not sure there's that much to know.

hello_i_am_a_new_array = %w{space separated stuff in here}
%w{space separated stuff in here}.any_array_method_here
%w{space separated stuff in here}.include?('separated') => true

It's just a simple shortcut. Example:

$ irb
irb(main):001:0> %w{one two three four}
=> ["one", "two", "three", "four"]
irb(main):002:0>

It builds an array of strings.

There is also %r for regexps.

This is general quoting syntax. qQwrx are valid specifiers.
