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?
Geomol

[8074x3]
:) 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
Kaj
29-May-2013
[8082]
Yes, I'll look into it
Geomol

How are Red scripts named? .r or .red or what?
Kaj
29-May-2013
[8084x4]
.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?
Gregg
29-May-2013
[8091x4]
Almost never for me.
BTW, my Red HELP experiment is here, under %Red/mezz/. You can paste 
it into a Red console to test.
Ah, yes. One issue was that calling HELP with no arg crashes the 
interpreter.
I might have stopped until we have errors in Red, because debugging 
by crashing is hard. ;-)
Geomol
29-May-2013
[8095]
yeah :)
Gregg
29-May-2013
[8096]
But also shows that you can still do a lot in Red, even without it. 
Most of the mezz code I did works.
Kaj

WHAT is quite essential on Try REBOL for new users
Gregg
29-May-2013
[8098]
It's never struck me as a great name. I just always use HELP. e.g. 
HELP function!
Kaj
29-May-2013
[8099x3]
It's very introductory, like What, Why, When, Where. You need that 
before you know to do HELP function!
I found a bug in the interpreter that currently prevents me from 
overriding DO:

Gregg
29-May-2013
[8102]
Except, we don't have WHY, WHEN, or WHERE. ;-)
Geomol
29-May-2013
[8103]
World should have a WHY??? :)
Kaj
29-May-2013
[8104x2]
I don't see how that devalues WHAT. :-) And R3 has WHY?
I don't remember which, but I think there are old computer systems 
that list available commands with WHAT
Arnold

WHAT is to find out what stuff is attached under an object. I use 
(d) it a lot with VID, finding out which field was filled with what 
value to see how I could go about dynamically change the properties 
like captions and values and colors.
Geomol

Arnold, isn't that what HELP (or the ? short) is used for? WHAT seems 
to "Prints a list of globally-defined functions.".
Arnold

[8108]
You are completely right, I stand corrected. Sorry, mixed them up, 
not using it as much lately.
Geomol

[8109]
Would it makes sense to add languages like Verilog as target / code 
backend to Red/System?
Arnold
30-May-2013
[8110]
Probably the WHAT has served an important purpose during development 
of REBOL?
Geomol
30-May-2013
[8111]
I couldn't say. I don't have any memory of WHAT, until it was mentioned 
here yesterday.
sqlab

I used WHAT many times, and also  when showing/demonstrating rebol 
to other people, what is built in
Gregg

[8113]
If someone needs verilog, they can add it (or pay Doc to). I need 
I/O and some networking, and the core stuff like errors and objects.
Geomol
30-May-2013
[8114]
Yeah, I was just thinking, if it makes sense at all to include a 
language like Verilog in the way, Red/System is made today. I haven't 
looked deeper into it. Maybe it makes more sense to create a cross-compiler 
from Red/System to Verilog and such, totally independent of the code 
backend found in Red/System?


Maybe Red/System could be the base for all different kind of hardware.
Gregg
30-May-2013
[8115]
I would probably think to implement as a high level dialect in Red 
that compiles down.
Geomol
30-May-2013
[8116]
Isn't that the other way around? I want to go from Red/System source 
to Verilog and other similar languages for different hardware. I 
don't want to start with a Verilog program and end up with what Red/System 
produces.
Kaj

[8117]
Doc wants to program FPGA CPUs dynamically one day, so there is a 
sensible route in there somewhere
Gregg
30-May-2013
[8118]
What I mean is, I want to write the Verilog/VHDL dialect in Red, 
and have it compile down.
TomBon

Gregg, you have a fine taste of useful tech ;-)

I guess this is a huge task. If you look at the Xilinx ISE Pack and 
the prices they are asking...

There is a free Web version but this one only supports the very small 
units with max. 24k LC, not enough todo usefull things.

But of course a Verilog/VHDL dialect would be more than cool. Meanwhile 
OpenCL/CUDA would be nice as well.

@Doc: found problem about console windows. I use the function _system() 
twice so I have two windows so it is my fault, sorry.
