Hello Tony,

Well, sounds nice for me! :D

So, just remember to you that the ** operator doesn't work with big numbers, this is not exactly only about performance, the interpreter returns an error when you have huge numbers, like

2** 400300

;-)

Cheers!

I added Numeric#times.

Don't worry, I will get the performance tuned at some point in the future, but right now things are in too much flux to start adding in performance optimizations.

Hi Tony, thanks for the reply..

I just made this modification because i *work* with huge numbers and combinatorial optimization, and the ** operator does not work with my algorithms, and i'm really interested to test your language with my combinatorial algorithms :D

playing with your source code, i also add a 'times'operator in numeric.re:

def call(self, :times, args, block)
list = erl.lists.seq(1, self)
erl.lists.foreach(block, list)
"ok"
end

BTW, really nice modifications on architecture! :)

Hello,

This may sound ironic given the context of this post, but I'm not really working on additional performance optimizations at this point. The goal of the rewrite was to get the language architecture on better footing, but at this point I'm not concerned about micro-optimizing.

Hello Tony, nice post!

I'm interested on Reia features, especially the '**'(power) operator. I saw in the code that you just
implement this feature using math:pow erlang's operator. I implement here another way to compute this. Here are the steps:

1. Create a reia_pow.erl file in core folder with the content
% Code example by Hynek Vychodil, introduced into reia's source code
%
% http://www.erlang.org/pipermail/erlang-questions/2009-April/043013.html

-module(reia_pow).

-export([reia_pow/2]).

reia_pow(X, N) when is_integer(N), N >= 0 -> reia_pow(X, N, 1);
reia_pow(X, N) when is_integer(N) -> 1 / reia_pow(X, -N, 1);
reia_pow(X, N) when is_float(N) -> math:pow(X, N).

reia_pow(_, 0, P) -> P;
reia_pow(X, N, A) when N rem 2 =:= 0 ->
reia_pow(X * X, N div 2, A);
reia_pow(X, N, A) -> reia_pow(X, N - 1, A * X).

2. Update reia_r2e.erl, changing

{remote, Line, {atom, Line, math}, {atom, Line, pow}},

to

{remote, Line, {atom, Line, reia_pow}, {atom, Line, reia_pow}},

Just recompile the source and you can perform commands like:

2**2048

in a faster way, considering bigger numbers evolving just integers

See ya

I'm not planning on beginning a reimplementation of the standard library until immutable objects are available.

As for an ETA on a stable, embeddable version? I don't know, at least another few months.

Hi, I'm thinking now about adding scripting support to http://erlyvideo.org/ and one of the choices is embedded Reia. How do you think, when will it be possible to embed testing version?

Any idea when the example lib (tcp, odbc, ...) is available in the minimal branch again?

Amazing, can't wait to try it out. Keep up the great work with Reia.
