Percent w and other ruby percent syntax

If you can’t find what you want to know about ruby percent notations ( %w, %q, %r, %x), then have a look over there:

Jim has obviously some other information sources than Google (where trying to search for %w is like trying to find your way in a dense steam room!)

The way to remember things is easy though:

• %w is for White-spaced delimited arrays
• %q works like Quotes
• %r wraps up nicely Regular expressions
• %x simply eXecutes system calls
