Hello,

looking in various site and various projects, it's seems that we don't a native basic interpreter on OS4.x. I think that a fast and easy developing environment (especially graphic oriented, like amos pro or amiblitz) it's needed.

Any thought?

How about Mattathias BASIC?

Maybe it's time for "A" now...

I would just need some help in the PPC Codegenerator, because I am not familiar with PPC and I don't have a PPC.
Here are the language specs (for experts only, its not a "beginners programming guide":

A/A++ Guide

Here is an early screenshot of AIDE:

Good idea.

Hope you will found help about the PPC part you have asked

thanks for the development of A+, I think the official successor of amiblitz ???.

I am not so big lover of basic, but your work looks professional. Like a lot when ppls do somethink good with many ideas in mind (about waittof() for example ;) ). Hope you will found some help.

I though that the development was halted.

Nice to see that it's in development.

Looking at A++ too.

There's Hollywood, which is LUA based. That's pretty close to BASIC

@Wanderer

Gimme, Gimme, Gimme!

Sign me up for any beta testing under 4.1(beta), I'll take anything you've got, I need to get back into coding and A/A++ looks good :)

I'd rather see REBOL ported to OS 4.x. When I tried it on my classic Amiga it was easy to understand, powerful and small.

As a temporary stopgap, you can try out sdlBasic since that will be the basis for the cross-platform runtime of Mattathias. The syntax will be more like Amos in Mattathias though.

-edit-
Keep in mind you'll need two specific fonts in your Fonts: directory for it to work.

Please note:

"A" is not implemented yet, it exists as specification only, that might still change here and there.

Is is not an official/unofficial successor of Amiblitz3. It is a different language. Till it will be real-world usable, I expect at least a year or so. If you want a cool programming language, use Amiblitz3

It is a language inspired by Amiblitz3 and C. The A++ Runtime Library however would be based on a port of the Amiblitz3 Includes to A.

AIDE exists as a GUI only, no functionality in it yet. Mainly I tested NTUI, a GUI Toolkit.
The only thing that exists in "VRun", this is the V-Assembler Interpreter. "V" is the Assembler that is generated by the "A" compiler. This virtual assembler is then converer to 68K, PPC or x86.

Development depends heavilly on feedback!

The first Version will be bootstraped in Amiblitz3. Future Versions will be implemented in A itself.

Target is to generate native Executables that a close to C speedwise, but I don't expect to reach 100% C or Amiblitz3, too much optimization would be needed. On the otherhand, programming should be easier and more elegant. OOP is integrated very smoothly.

PureBasic could be something...

Rebol it's a cool Language.

I saw it in action. It's fantastic. Rebol, moreover, could run very well on EXEC NG ;)

Porting Rebol to OS4 will be much easier once Rebol v3 is done, because that will open source much (but not all) of the code necessary for porting it.

@Wanderer
It is a shame that "A" adds C++ style syntax onto the BASIC language, as IMHO that turns a nice readable language into an ugly unreadable one . (If you want an example of a better way, one which would actually fit with BASIC's style, then I direct you to AmigaE & PortablE.)

@Wanderer

If you want A/A++ to ever be cross-platform, you'll need to rethink your implementation of macros because installing from a common bytecode would require that all of the system-specifics be included in the bytecode file itself. This is a problem that prevents C code from implementing a bytecode, by the way.

I don't mind some of the syntax conventions of A/A++ but it doesn't look like it is being written from the ground up with cross-platform compatibility in mind. Is it supposed to be AmigaOS/AROS/MorphOS only?

@Samurai_Crow

can you post a "status update" of the development, please?

Thank you

What is taking so long for the Mattathias project is that, in preparation for writing a language that is more flexible than any other, we have to write new tools to build it. We are currently working on an interpreted parser generator that will allow us to debug the generated code and parser all in one sweep.

We are using LLVM as our bitcode so we'll be able to support many processors without having to write our own intermediate code format or optimizer. This is a commercial-quality compiler toolkit. Apple is going to use it to replace GCC in its own toolchain in conjunction with their Clang project.

Once the interpreted compiler generator is done we'll continue development of the parser for the language itself. We were planning on using the sdlBasic runtimes for the first draft of the language.

@Wanderer

Since the AmiBlitz team seems to be experts in the generation of 68k code, perhaps you would consider writing an Amiga 68k code generator backend for LLVM instead of writing a new intermediate code representation. It would generate better code than any existing 68k compiler with the existing code optimizer that LLVM comes with and then we could use it to develop all of the rest of the compilers with.

By the time your team would have finished with that, our team will have finished the parser generator so you could use the parser generator to write your A/A++ language with.

Also, ChrisH had mentioned that his PortablE compiler has a modular backend and could benefit from an intermediate language interpretation as well. He has been using either AmigaE or C++ as a backend so far but LLVM would be much faster.
