Variables starting with ":"

ruby-talk

What's the diference between regular variables defined as, lets say
"example", and the ones defined as ":example" ? If there's a

difference,

when should each case be used?

Items that start with a colon are not variables, they are Symbols.
Continue your research with that bit of information; there's a lot out
there on the difference between Symbols and Strings (in 1.8), and when
to use them.

Thanks a lot, Gavin. Now I know what to look for.. I've never read about
Symbols before on any of the books I've read so far.

Thanks!!

Be sure to check out this ridiculously long post on the subject. I'm still
digesting it (seriously, it was crunchy at times, and it sits kind of heavy
in the belly but it's worth it. )
