Lisp in Basic

[Aurel]

Rob what is this ..
need Java  ....where is a lisp?
..and yes Lisp is not language for hobby programmers at all...
and i really ..really don't understand your obsession with Lisp ..
are you member on any Lisp-forum ..or something?

.

Hi Aurel,

Yes, it needs Java to run -- it uses the Java Programmable Interface for the graphics.
Nono, not a member of a Lisp forum -- (my avatar is even my outfit when attending Lisp gatherings    as said before they are specialized in humiliating "the others"  )I fully understand the shortcomings of Lisp , but I also do understand its powers.
I also do understand same for languages as Pascal and Basic.
The symbiosis is happening ..  the now popular languages ..  Python , Ruby , Haskell contain a very lot of Lisp  -- what I'm hoping for is a language with both the strengths of something as basic together with something as lisp.

It certainly is not religion -- just my ideas are faster materialized with lisp ,  it may be a consequence of the job I did, I don't know -- I certainly will never do any categorizing concerning prog. lang. As said, I do understand the strength of imperative languages as basic     --   and I simply can not comment on many languages, simply because I do not know them.

best Rob

Aurel,

I would like to say that i prefer to believe in new languages like is PWCT than in this hybrid basic-lisp.

This project isn't intended as a basic-lisp hybrid. It is LISP written in BASIC. Same as thinBasic written in PB. Same as Oxygen written in FB. Same as Ruben (is it ruby?) written in O2.

PWCT is a Lego for script kiddies, a VB6 IDE promoted to the nth power of absurdity, and the essence of John's point & click nightmare. This paradigm has in fact been very well known to mankind for ages: if VB6 is a kindergarten, then PWCT is its nursery.

Rob is perfectly right in saying that there isn't really a question of a language vs. a language (you can't embrace the unembraceable in one hug anyway) but a language plus a language. The more pluses one has, the more powerful one is.

Charles,

This example indicates what is possible with o2 autoconversion, instead of using explicit conversion, or variants.

Excellent!

While this isn't strictly "instead" but rather "halfway there", this should be more than sufficient for the needs of BASIC LISP in its Oxygen implementation.

Thanks a lot for the tip!


[EDIT] Will Oxygen's string functions, for example STR(), handle the elements of such an array as s[n] in you example correctly? Is garbage collection solid when re-assigning string/double/string/double/... values to the array elements?

Hi Mike,

Is there something to update the SBLisp code with or is the current source it?

[Mike Lobanovsky]

Hi John,

Not yet. Everything will be posted here immediately when ready.

[JRS]

Thanks for the update Mike!

Can you post the top 5 SBLisp SUB/FUNCTION routines that would best be served by a C conversion?

I often check for missing garbage collection calls in such expressions. So far so good, but you may yet discover a leak in some novel combination

yes Mike maybe you have a right BUT how then explain that this project have
more & more users...
I don't understand what this people see in PWCT.
i am not impressed....

[JRS]

@Aurel - Can you start a new PWCT thread and stop hijacking this one?

[RobbeK]

Thanks Mike,

Bouillon ,,   maybe "борщ"  -- the colour in the middle sometimes matches ... 
Set up C-pointers now in CLisp , Clozure CL and Steel Bank CL  -- that Bigloo document helped a lot to understand things ...

best ,  Rob

ah, yes for the XBlisp Mandelbrot imho the most easy way is to set up a list with coordinates '( (-1.5 -1.5) .... (1.5 1.5) ) , then defining a function that takes a list (x y) - do the calculations when it bails out -- this function will be mapped on the list - resulting in a list of orbits -- with this (and (nth i L) ) it is easy to make a representation.  It surely will work , but it's all recursion.
It's all in my head -- should I code it -- resulting exec time may be very long...

Hi Rob,

It's all in my head -- should I code it -- resulting exec time may be very long...

If it wouldn't take a lot of your time that would be great. All SBLisp Scheme code is helpful for testing the interpreter and for benchmarking between variations.

These should probably be GarbageCollect and its callees. But actually their code may still change. I understand your eagerness to do something useful but please don't rush me.

I split and convrted everything and got rid of bsd completely. Still there seems to be a typo left somewhere because files still don't want to load and get read properly. Interactive sessions seem to run OK.

Please have patience.

[Mike Lobanovsky]

Rob,

I second John's request and I'd like to make it even more imperative. We need code-intensive XBLisp programs for more thorough testing.

Speed doesn't make any difference at this point. Everything will a hundred times faster when translated to C and DynC and when OxygenBasic's JIT version becomes operative.

But we need the programs now. We don't have much time to design them ourselves because we are complete noobs. Mandelbrot will take you minutes to write but it will take us days to do the same.

MacRob, where are you with our ASCII Mandelbrot?
