Announcement (2017-05-07): is now read-only since I unfortunately do not have the time to support and maintain the forum any more. Please see and for other Rails- und Ruby-related community platforms.

those whom interested in both ruby and erlang,
I'd like to showing my small work.

I've been implemented a bit of ruby classes (String, Array, Range,
Regexp ,,,) using by erlang.
so could do something like

A = ruby:new([1,2,3]),
Stack = ruby:new([]),
[1,2,3] = (A(each))(fun(X) -> Stack({push,X+1}) end),
[2,3,4] = Stack(value),

I sent this to the erlang mailing list on a couple of weeks ago,
and got no replys.
well, I felt that erlang programmers don't like this :)

so what I really want to do is that
you know, erlang's powerful concurrency.
check this working between two erlang nodes.

$ erl -sname b
(b@woo-kyoung-nohs-computer)1> A=ruby:new([]).
(b@woo-kyoung-nohs-computer)2> A({register, a}).

$ erl -sname c
(c@woo-kyoung-nohs-computer)1> N='Node':'Node'({a,
(c@woo-kyoung-nohs-computer)2> N({push,1}).

(b@woo-kyoung-nohs-computer)3> A(value).
(b@woo-kyoung-nohs-computer)4> A({push,2}).

(c@woo-kyoung-nohs-computer)3> N(value).

you could get the code from

svn co
cd ruby
make test

thank you.
have a good one.

I'm sure Erlang has fascilities for doing what you're doing without
faking Ruby. What's the value in using a crippled library nicked from
another language? Perhaps the users of the erlang mailing list simply
didn't understand. I don't think I understand either. What do you hope
to achieve by embedding Ruby standard classes in Erlang?

If you're trying to implement Ruby on the Erlang platform, I bet a lot
of people would be interested, but simply being able to fake Array,
String, Range etc. just isn't very interesting IMHO.

My guess you didn't get a reply is because it's like reinventing the
and add warts to it.
Compare with list comprehension
A = [1,2,3],
S = [X+1 || X <- A].

or even
A = [1,2,3],
S = lists:map(fun(X) -> X+1 end, A).
