meta Meta language released

[Kaj de Vos]

Ah, thanks. That's the kind of feedback I need.

 

Next up is an update of the underlying runtime in this executable. I will let you know when that is in place, so we can see if Windows and FreeBSD improve.

compiler that can be used locally - at least for me it's a very poor workflow when to compile even "hello world" I need to send it to Internet.

Do you program without an Internet connection?

Well, I do of course, but I don't want to have to just to write programs. My opinion.

[Kaj de Vos]

I understand that, and I agree. It just won't be possible with Meta for a considerable time to come. Meta will achieve almost unprecedented platform reach soon, but the other side of that is that it needs many different, highly complex and hard to handle existing C toolchains.

[danwinslow]

Well, if its a temporary situation, that's understandable.

Your desire to cover many toolchains will keep you busy for a long time. Consider an adapter layer, something like maybe what LLVM does, meaning a universal intermediate compilation that then gets run through a particular adapter that would then express the correct source and drive the toolchain.

[Kaj de Vos]

Well, Meta is that adapter layer, and C is the intermediate language. Even if have already spent a large amount of time on Meta, it is still a limited intermediate layer between REBOL and C.

[danwinslow]

Ok....well, you said "it needs many different, highly complex and hard to handle existing C toolchains". That was what I was talking about. If you got it covered design-wise already,, great.

[Kaj de Vos]

I am being greatly rewarded for implementing a C back-end, because I can use many great C toolchains and libraries. But there is a wide range of them, which is the point, so I still need to integrate them all.

I have added a downloadable file of Hello World:

Added the Rainbow graphics example to the website:

I tried it on an AMD64 PC running FreeBSD 10.1. The result: illegal system call (core dumped).

It turns out you need FreeBSD 12 or newer. Are you able to test on that?

 

I worked out all the required versions and added them to the website:

https://language.metaproject.frl/#get

 

For those who tried on Windows: does Meta output text properly, or does the cursor in the command window not advance properly, so that text is overwritten?

Compiling file rainbow.meta

Result is in file program.xex

works :]

I tried Meta but failed. I didn't get very far without the Atari specific examples. One rainbow example is far too little.
 

Try port this:

https://github.com/KarolS/millfork/tree/master/examples/a8

 

https://github.com/zbyti/k65-playground/tree/main/src/a8

 

not all of them, of course, but those that are now been possible.

This language looks almost as good as BS

C'mon now. It's his thread and his pet project. No need to get sassy, he's been perfectly polite to all questions and criticisms.

Doesn't run on Atari.

Currently fixing a regression that blocks the others.

I've been looking at those. It seems to me it's a nice task for you. ?

I watched the video on BS and I must say I have to agree

 

[Kaj de Vos]

Added the inline assembly version of the Rainbow graphics example to the website, including comparisons with Millfork and K65:

https://language.metaproject.frl/#examples

[zbyti]

Don't forget about Mad Pascal

 

var
  RTCLOK : byte absolute $14;
  COLPF2 : byte absolute $D018;
  COLBK  : byte absolute $D01A;
  WSYNC  : byte absolute $D40A;
  VCOUNT : byte absolute $D40B;
  a      : byte absolute $e0;

begin
  repeat
    a := RTCLOK + VCOUNT shl 1;
    wsync := a; COLPF2 := a; COLBK := a;
  until false;
end.

; --- RepeatUntilProlog
l_0061

; optimize OK (rainbow.pas), line = 11

	lda VCOUNT
	asl @
	add RTCLOK
	sta A

; optimize OK (rainbow.pas), line = 12

	sta WSYNC
	sta COLPF2
	sta COLBK

; optimize OK (rainbow.pas), line = 13

	jmp l_0061

I couldn't find it. Is there a link to that?

[zbyti]

it can be easily fixed @tebe please do your stuff :]

Thanks! I added it to the site. Also added the mixed Meta/assembly version:

No, and my own FreeBSD box is an i386, so even if I upgraded the system to 12+, it would not help much, I guess. But do not let it bother you, I am writing my stuff exclusively in assembler anyways and I prefer to do that directly on the target machine, so I am only marginally interested in high-level programming languages, the less if these are cross-compilers only.
