The main drawback right now to support direct Red script execution 
is REBOL inability to execute native code from memory. The workaround 
would be to provide a DLL to pass the memory pointer and call the 
Red code, but as I aim at a single Red binary, this option wouldn't 
be very satisfying.

I would prefer Red to compile either to the directory, where the 
source is by default or at least not to the system/options/home path, 
but to the path I get with pwd

Agreed, change done.

That's quick. Thanks

I got math ops for integers working, but I think it's time we get 
a better macro system.

quick-test has been broken by one of the last 13 commits in branch 
v0.3.0. I'll try to sort it out over the weekend.

That was under OS X, it runs okay under Windows.

So time really is running out for REBOL

quick-test is also broken on Linux.

Peter: let me know if I can help.

Very exciting to compile hello.exe on my Windows PC!

Kaj: what do you think of that? (for Red/System)

    #define MAX(a b) [either a > b [a][b]]

    print MAX(78 12)

outputs: 78

Try it the other way around ;-)

Huh! :-)

Works! (was testing in the wrong console)

That's good ;)

I take it for granted that this is just on the way to having maximum: 
max block-of-values ?

and it returns the max in maximum?

I think he's just working on macro support in this example.

that makes sense.

Arnold: it's for Red/System, not Red.

Nice features of the new macro support: 


- the replacement in the argument block operates for any block series 
(includes paths types)

- nested macros in macros are resolved


- you can define the argument as paren! instead of block!, and paren! 
will then stay once macro resolved.

Here's a more complex example:
    
    #define MIN(a b) [ either a < b [a][b] ]
    #define MAX(a b) [ either a > b [ MIN(p/a p/b) ][p/b] ]

    p: "Hello"
    print MAX(2 1)

outputs: H

(in fine, MAX(2 1) resolves to: p/1)

Nenad, thank you for the explanation. Good to know even the simple 
test works both ways, and I am a programmer not a tester ;)

New macro system pushed online in the v0.3.0 branch. If anyone needs 
it in other branches, let me know.

hello.red segfaults on my ubuntu 12.04 system, any idea?

No, I haven't yet tested the Red codebase on Linux, but I will in 
a few minutes.

So I am the first one to test it on linux? :)

It looks like. ;-)

Cool, it compiles anyway.

Doc, did you know you have a possible theme song? It goes back to 
when I was a young lad but it still rocks:  "Red" by Sammy Hagar.

Nice Red rock song. :-)

I did this 
$ git clone https://github.com/dockimbel/Red.git

so how come red.r doesn't come down?

I got the redme.md and the license ...

hmm..lots of files don't come down

ooops .. my bad

anyone know how to pull this branch down?

If your `git clone`succeeded, `cd`inside the repo, and do a `git 
checkout origin/v0.3.0`

thanks .. found the answer on SO too

Math operations now supported in Red (integer! values only for now). 
For example:

    a: 123
    a: a + 2
    print a * 6 - a

will correctly output 625.

@szeng: I will look into the Linux issue tomorrow.

I'm awed by the great elegance of it all

The code is very accessible

I like the new macro system, too. I've wanted that for a long time 
(in silence :-)

We'll inform Peter Busser that Red supports round brackets now ;-)

I've updated the recipe in the Syllable build system to add Red:

http://syllable.cvs.sourceforge.net/viewvc/syllable/syllable/system/apps/utils/Builder/packages/Red--current/

On Linux, the executable ends up in the directory of the compiler, 
instead of the working directory

I can confirm the segfault on Linux

Hm, I see Exec in the code :-)
