Re: native calling

[Mike Pechkin]

It needs clear:
o) you create demo picolisp code without native calls as demo and startpoint
o) I need a list of library functions you gonna use
o) I create native wrappers or something
o) you glue your code and native

It needs a different call:

   : (scl 6)
   -> 6

   : (java "java.lang.Math" 'sqrt  (-6 . 64.0))
   -> 800

   : (round @)
   -> "8.000"

As you probably know, the Java interface is described in
http://picolisp.com/wiki/?javacode

It writes:

   While integers are directly passed to/from the JVM, other number formats can
   be passed to the JVM as cons pairs consisting of an ID in the CAR and the
   value in the CDR. These are:

• 1 for Byte
• 2 for Char
• 3 for Short
• 4 for Integer (default, usually not needed)
• 8 for Long
• 9 for BigInteger

   If the CAR is a negative number, the value is taken as a double scaled by the
   negated number of digits.

Re: JavaCode with static class methods

[Joe Bogner]

Hi Thorsen, it looks like you were on the right path. I'm guessing there
may be a bug or issue with the double signature

This works:

: (java (java "java.lang.Math" "abs" -4))
-> 4

: (java (java "java.lang.Math" "min" 10 5))
-> 5

But I'm just guessing

Re: native calling

[David Bloom]

Either of these two single header C libraries is where I'm considering
beginning my journey with native calls:

nanomsg - a spiritual successor to ZeroMQ
http://nanomsg.org/index.html

Or

nuklear - a slick looking, small ANSI-C GUI
https://github.com/vurtun/nuklear


I'm happy to pitch in code as well but still have much to explore in
PicoLisp and so may provide noobish codezezez.

Thanks for the reminder. I'll add it in.

Enjoy.

Gratitude makes any experience more enjoyable. It doesn't make the journey
any less new, the effort any less real.

JavaCode with static class methods

[Thorsten Jolitz]

Hi List, 

I'm experimenting a bit with the 'java' function, and the StringBuilder
and GregorianCalendar example from the JavaCode Wiki entry work fine,
but I wonder how to use a constructorless class like e.g. java.lang.Math
with its static class methods?

#+NAME: JavaCode - none of these work
#+BEGIN_SRC picolisp
(java "java.lang.Math" 'sqrt 4)
(java java.lang.Math 'sqrt 4)
(java 'java.lang.Math 'sqrt 4)

(setq M (java "java.lang.Math" T))  // returns null, no constructor
#+END_SRC

Thanks for any hints.

Re: native calling

[Joh-Tob Schäg]

I am not sure this sensible or even doable, but a binding to the torch
library (http://torch.ch) would be cool. Since Picolisp could use high
speed high dimensional math and machine learning.
It is written in C++ and already has a LUA interface. It needs a newer (< 4
years, i guess) NVIDIA graphics card to run.
GNUplot could be usefull too.

Hi, this looks cool and I want to play around with it, but licensing
information is not clear. Could you please add clear licensing/copying
terms to the repository (ideally on each source file)?

native calling

[Mike Pechkin]

hi,

I need more experience in (native) usage.
If somebody need library bindings to something you can request here or
directly.

Perfect! I have already started working on it. I have one last file to
write. I will send it to you once I finish. It would really help if
you could review it once. Alex can then merge the code into his master

Self-similar fractal curves on canvas

[Lindsay John Lawrence]

I developed this a bit more.

https://github.com/thinknlive/picolisp-gosper

I think now it may be a nice little tool to explore these kinds of functions.

You can step draw the results, or draw all at once.  You can also
modify the lisp function code and then reload the module to try the
changes immediately without restarting the service.

I'll add more over time as I think of it. Perhaps zoom and navigation
buttons, buttons to change the step size and refresh rate from the ui,
etc.

The picolisp ui framework makes this so easy.

/Lindsay
