12:43 <stefanos82> greetings everyone. I wanted to ask: I have found in my public library the Programming Ruby book, the fourth edition. How outdated is comparing it with the latest fifth edition?

12:43 <stefanos82> are there major differences between them?

13:01 <adam12> stefanos82: Not sure the publish date on it. Any idea?

13:01 <stefanos82> 2013

13:01 <adam12> stefanos82: Ruby hasn't changed _that_ much over the years but there are some subtle differences.

13:01 <stefanos82> syntactic sugar and such?

13:01 <adam12> 2013 should be OK. You might be missing some of the newer stuff but a lot of things would probablly still work.

13:02 <stefanos82> yeah, if the gist is the same and the rest can be found in official documentation, I'm sure I can catch up in no time

13:02 <adam12> Sure. No pattern matching. Keyword args might be a little different. Some methods have completely gone away (File.exists? for example) so you might have issues there.

13:02 <stefanos82> ah I see

13:02 <adam12> I'd just try it then ask questions for what doesn't fit.

13:03 <stefanos82> sure thing

13:03 <stefanos82> thank you for your valuable feedback adam12

13:03 <adam12> stefanos82: You're welcome!
