thanks a lot

ok, i must admit that i don't have understood the 100% of the replies; i have little knowledge in C and newlisp, two thing that i'm start using because i want to learn more about programming (right now i'm a java programmer) So, from the start, what a bridge would look like? In my mind it would simp...

thanks lutz,

but how did you know that? is it documented somewhere ?

just curious... in the case i'll encouter a similar problem with others lib

Reading the comment on the opengl demo (http://www.newlisp.org/syntax.cgi?downloads/OpenGL/opengl-demo-lsp.txt) i've read that on ppc i'm not able to see the drawing, and that's true, but could someone explain me why? It's because float and double are passed correctly only on x86 as i read here? htt...

Lutz, with 'callback all works great !! here is example code using OpenGL and GLUT for registering callbacks: http://www.newlisp.org/syntax.cgi?downloads/OpenGL/opengl-demo-lsp.txt it works well on Mac OS X (Intel processor required) with nothing additional to be installed and works with the GLUT Fr...

hi newdep, can you have some example code using glfw? I'm using newlisp + glfw 2.6 + osx, i've made a little test to see the how "key listener callback" could work, but when i type sometingh the application crash... so i don't understand if i made some mistake ... here is the code: (load "glfw.lsp" ...

my vote is for the solution number 1, with this "exception":
the first element of a non-quoted list is special, if the list is quoted all element are the same

wondering if is possible to have the function name with a different color;

today the function name and its arguments are all in the same color,
if is possible (asking because i don't know vim syntax well)
would be nice to have "visual" separation between the two ...

WinXP and newLISP 9.2.0 here

it return an error:
on my default installation (env "NEWLISPDIR") return nil

Thanks

I'm reading a book about Lisp, and the examples are all for Common Lisp;
In the code they pass a function as a paramter, then use "apply" to "call" the function ...

but you're right, i don't need apply

Edit:

they use funcall, not apply

How can i "call" a function and get back the result? Here an examples to explain: (set 'my-func 'integer?) (apply my-func 1) => nil How can i "apply" my-func and get back the return value? (true in this case) I've found that this works (set 'my-func 'integer?) (apply my-func (list 1)) =>true but is ...

thanks cormullion, you're right. I need also to change this line in my script (while (read-line myin) (write-line)) with this (println (read-line myin)) because with the "while" launching the script ends with the same "new line waiting input" Is "bc" that doesn't end the "communication" with a line-...

I'm trying to run the example found in the documentation about process (map set '(myin bcout) (pipe)) (map set '(bcin myout) (pipe)) (process "bc" bcin bcout) (write-buffer myout "3 + 4\n") ; bc expects a linefeed (while (read-line myin) (write-line)) (exit) I've added a write-line and an exit call....

@Lutz it would give you back an integer but everything coming out of floating point has only about 15 digits of precision, while with int yuu get to about 18 digit. Casting to an int doesn't give you back precision and will cut off all decimals. thanks Lutz, didn't know about the difference in the d...

umm...

but if i want integer precision then i can "cast" to integer right?

someting like this

(int (add 1 1.5 2))


probably it works only on 32 bit integer ?!

Hi all,

i'm movig my first step with newLISP and Lisp in general,

I'm just curious about the +,-,*,/, ecc...
why they return only integer number?
