Yesterday I got a book called "Learning ruby - O'reilly" which was published in 2008.

Now I see that people use Ruby version 2.3 or higher

This book is based on Ruby 1.8.

Is there any problem in studying with this book?

I think

If it were quite different, it would be a problem.

If not, I will have to study a little more chapters.

I want to study with that book as much as possible.

I'd appreciate it if you could give me some more chapters to add in 1.8.

I would also like to let you know some of the information about the update history between Ruby versions.

(It's not obligatory, I can find it somehow :))

Thank you.

I recommend you to find a newer book. Ruby had important changes from version 1.8 to 1.9, including new syntax.

A couple of things I can think of:

* This is valid syntax in 1.9 but not in 1.8: {a: 'value', b: 'value'}.
* This is a valid method definition in 1.9 but not in 1.8:

```
def method argument
# stuff
end
```

Eh...? I have Ruby 1.8.4 on one of my older machines, and I copy/pasted
the above into it. It compiles fine -- and can be invoked: e.g.
"method 11" (returning a nil result). Am I missing your meaning?

Re the original query, I still find my 'Pickaxe' book for 1.8 an
invaluable reference, even for Ruby 2.2. It's the new [absurd (:-/)]
behaviour of strings that I have to keep diving to the web to sort out.

$ /usr/bin/ruby --version
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

As you see, i'm also 1.8.7 on Ubuntu 12.04.

Just for study, no problem with ruby 1.8.7, i think.

Sincerely,
