Hi there,
I'm about 2 weeks into my learning attempt at Ruby (1.8.6 is what I've
cut my teeth on).
Can someone give me a rational assessment of the differences between
the two language versions, and which one I should continue to pursue?
I'm mainly using Ruby with Rails to make basic webapps for my own
edification.
Thanks!
Alex
Very short answer:
- new virtual machine (previously just AST interpreter)
- memory diet for some objects (Object, Array, String etc)
- improved speed (see
http://antoniocangiano.com/2008/12/09/the-great-ruby-shootout-december-2008/\)
- added character encoding support (previously works only with raw bytes)
- new syntax for hashes with symbols as keys, hashes preserve keys order
- many changes to API (improved, added consistency, removed deprecated code etc)
- changes in language semantics (for example block arguments now works
(almost?) the same as method arguments)
- new lambda literal: ->
- external iterators (class Enumerator) now are built in
- new concept such a fiber (class Fiber)
- native threads (but with GIL like python)
- rubygems, rake are built in
- minitest supercedes old test/unit

Hey Alex,
How is your learning process going? I'm currently learning Ruby also. I
picked up "Beginning Ruby" by Peter Cooper(Excellent read), and "Design
Patterns In Ruby". What kind of projects are you creating and practicing to
sharpen your skills? I need some simple projects to start creating. Do you
have any suggestions?
Thanks

Keep going with 1.8. There's more in 1.9 and strings are unicode.

AFAIK, Rails isn't available for 1.9 yet, and much of the good stuff in
the Ruby 1.9 APIs is actually inspired by and taken from Rails. Stick
with 1.8 for now. Learning the new stuff for 1.9 should be relatively
easy -- I've been able to move some code I've written for 1.8, and run it
on 1.9 without changes and all unit tests pass.

So since these changes have been made, will us noobs be hurting ourselves
starting off learning 1.8.6? Books to learn from are teaching from 1.8.

You might try some of the easier questions from Ruby Quiz:
The problems a bunch of people solved are generally the easiest. For example, have a look at:

I don't think so. I can name only one thing (Symbol#to_proc) which was
popularized by rails (and even not invented by rails itself).

If you can wait about 1.5 months or so you can read "The Well-Grounded
Rubyist" (already available in early-access PDF), which is about
1.9.1. See http://www.manning.com/black2\. Meanwhile there's a ton of
stuff you can learn in 1.8.6 that hasn't changed, or where the changes
are likely to make more sense to you anyway (like "abc"[0] being "a"
rather than 97).
See also my recent blog posts on 1.8/1.9:

Not all books. Take a look at Programming 1.9 by Pragmatic Programmers
(http://preview.tinyurl.com/7xfvk7\). They constantly update their PDF
books to keep in step with the latest changes to Ruby.
Good luck.

No, you will be fine. It's not a super tough transition when you are ready.

In addition to those already mentioned in this thread, Flanagan's _The Ruby Programming Language_ (O'Reilly) is a great book in general and touched on Ruby 1.9 even though it was published over a year ago. It's not completely up to date with 1.9.1, but covers many of the conceptual changes.

I think things are looking up for Ruby 1.9 books, actually. Here's
the path I'd recommend (with some obvious bias)
= To grasp the fundamentals
"The Well Grounded Rubyist" [0]
= To understand the details
"Programming Ruby 1.9" [1] and/or "The Ruby Programming Language" [2]
= To use Ruby effectively
"Ruby Best Practices" [3]

This will give you a very well rounded experience, and once you
understand Ruby 1.9, quite a bit of your knowledge will still transfer
smoothly back to 1.8.
Most of these books are in Beta right now, all except [2], but if you
pick them up know you will help us catch problems before we go to
print, improving the situation for those taking the plunge directly
into Ruby 1.9.

HashWithIndifferentAccess?
Thanks Guys. So in a short list, what should be the features to stay away
from in 1.8, I just purchased "Beginning Ruby" by Peter Cooper, I really
would hate to struggle trying to get something then find out its no longer
needed or being used in 1.9 lol.
