World: r4wp

Some funny slides in there!

How REBOL began 14 years ago...

 - and then an image from the frech revolution with REBOL flags, onto
... and where it is today

 - and the image of a raft at sea with no sight of land, people suffering 
 and great despair.


You need a viking ship in there maybe, sailing off for new adventures 
in a new World.


I feel, Red is a good project, and with BSD license, it should be 
possible to give and take easily, right?

yes, you are correct, you can eventually use its code freely. But 
I think it will not be of much usage to you - Red code compiles to 
Red/System, which I regard being something like VM for Red. I also 
think, that you are free to take some code from R3, which is C code, 
and might be more usefull to you, and hopefully Apache2 license fits 
here too ....

Red/System is also BSD license, isn't it?

yes, it is ....

Seems to be BSD-3 ... but you can check it on Github ....

So I could see World benefit from Red, thinking of JIT-compilation 
or Rebcode kind of feature, and I could see Red benefit from World 
in some of the mezzanines, I've done already, and maybe some of my 
closed source code, that target a certain problem, like the multi-line 
input in the console (blocks and long strings going over more lines). 
And maybe World could even get a garbage collector from Red, as for 
example Gregg ask for in World.

Some johnk at the StackOverflow chat asked for the multi-line code 
from Carl. I've got that in World, if anybody can use it.

So - are you willing to exchange the code for the good, even if World 
is closed source? That would be nice of course ...

Red has some basic multiline IIRC too, in its console ... But surely, 
and maybe your offer could be posted in REBOL3 group here ....

Yes, I am.

Do you have parse already implemented? :-)

yes, as mezzanine. Look for bparse, split-string, sparse and parse 
in
https://github.com/Geomol/World/blob/master/cortex.w

I guess, it can be easily ported to Red?

I think, string parsing is not 100% yet (need to do more tests), 
but block parsing should be there.

Thank you Kaj for your reply.

It would surely be interesting to try to port the World mezzanines 
to Red

My multi-line implementation is here in console.red. It's fairly 
complete; not sure if you have more:

No GC in Red yet, though :-(

The viking ship is how I always thought about it :-)

The license for Red at bottom of
https://github.com/dockimbel/Red/blob/master/README.md

state, that the runtime uses the more permissive BSL license. Why 
this distinction?

:) Yeah, us crazy vikings.

Because Red needs to compete with other compilers. Classic compilers 
insert only very small pieces of boilerplate code, so that's free 
of rights. Red inserts the entire runtime and interpreter in compiled 
programs, but it needs to compete with that freedom

And Red owner could get into trouble, if not giving permission or 
what?

No, but people would complain that when they keep programming in 
C++, their executables are more free

Licenses kinda sucks, don't they?


When Mozart visited the sixtin chapel in Rome in 1770, he heard a 
secret piece of music, Allegris "Miserere". From memory, he wrote 
the piece down with all 12 voices or how many, when he was back at 
the hotel. Later he received an order from the Pope. Licenses kinda 
remind me of this. Why show or play something for someone else, and 
then at the same time say, you can't use it? :)

Yeah, it complicates things a lot

So far I have mostly talked about the ability to write R3 extensions 
in Red and Red/System, because I made a specific bridge for that. 
But with Red's ability to generate shared libraries, you can also 
make generic extensions for other systems, such as R2 and World. 
You can write libraries in Red and then import them with the DLL 
interfaces in World and R2

nice

If you see any code from me, be it mezzanines or C source or anything, 
use it, if you can! And I don't ask for specific mention. If people 
feel, they got some pieces of gold and wants to mention, where they 
got it from, fine.

Thanks, that's great!

But a viking deserves a rune stone in his memory, don't you think?

:) I'll create my own rune stones. (Any someone may create one too, 
but I don't ask for it.)

*And*

I got the red-core interpreter running here btw. That was easy. But 
I miss a HELP function in there.

And I see a lot of functions, so it seems to have come quite a way, 
but no DO of scripts?

Gregg is working on HELP and WHAT, but it seems to have stalled

I/O is not in Red, only in my extensions. DO is the internal interpreter, 
so it doesn't know about my I/O. It's a good point, I should try 
to override DO

You can start a script when you give its name on the command line, 
even a URL

I think, it would be a lot easier for e.g. Gregg to create mezzanines, 
if he could do a script with them, like cortex.w and rebol.w in World.

ok

Yes, I'll look into it

How are Red scripts named? .r or .red or what?

.red but it doesn't really matter

Note that, even if DO and LOAD currently don't work on files, you 
can still use:

DO READ %file

DO READ "url"

ok, good enough for now, I guess.

Red HELP func made some decent progress, but I stopped work on it 
because of some issues, and I didn't want to distract Doc until he's 
done with Android.

I looked at REBOL WHAT function, Kaj mentioned. I don't think, I've 
ever used it. Is it commonly used by you guys?

Almost never for me.
