newLISP in the real world / Enhancement in UDP for newlisp [ broadcast ]
February 28, 2004, 03:34:46 AM
Hello Lutz,



Is it an Idea to enhance the UDP functionality with SO_BROADCAST ?

The setsockopt needs an #SO_BROADCAST $0020 and a #SOL_SOCKET $FFFF in that case and a newllist function like net-broadcast-udp ( int-socket ) will enable/disable broadcast on the UDP socket. I had a look in your great C code but did not dare to touch it myself ;-)



* just tried it but got stuck ;-)

newLISP in the real world / 5 Cents tip for today [ help ]
February 27, 2004, 04:24:46 PM
If under linux or Bsd you want a help started, use the "init.lsp" file.

a simple edit like below will give you a direct local help.



;; start links web-browser and loads the manual

;; a function called (help) is now global

(define-macro (help)

        ( ! "/usr/local/bin/links /usr/share/doc/newlisp/newlisp_manual.html" )

        (global 'help))

newLISP in the real world / rotate on list
February 27, 2004, 11:58:02 AM
Hello Lutz,



(Linux 7.5.4)



Im currious what im doing wrong in the following example, perhpas you can

point out the mistake. I could emagin that (net-sessions) is static in itself still the first rotate Is accepted.



>(net-sessions)

(4 3)

>(rotate (net-sessions))

(3 4)

>(rotate (net-sessions))

(3 4)



As you can see the 'rotate only worked once, still rotate is destructive to the

'net-sessions list, its not updated a second time. If you would say that i should isolate the list from 'net-sessions befor doing a rotate (because of the dynamic/static behaviour of the 'net-sessions list) i'll work with that ;-)



Ofcourse a normal list works...



> (set 'x (list 1 2 3 4))

(1 2 3 4)

> (rotate x)

(4 1 2 3)

> (rotate x)

(3 4 1 2)

> (rotate x)

(2 3 4 1)

> (rotate x)

(1 2 3 4)

Norman.

newLISP in the real world / net-close
February 26, 2004, 12:57:39 PM
Hello Lutz,





Just a currious question..



When using 'net-close in a new started console the following happens;

and i was just currious if behaviour is related to the stderr stdin stdout?



>(net-close 0)  # loops the console prompt



>(net-close 1)  # waits



>(net-close 2)  # returns true



PS: it would actualy be nice to be able in newlisp to have

access to a list using network functions, like: (net-close (net-sessions))





Regards,

Norman.

Thanks Lutz...

newLISP in the real world / lists
February 25, 2004, 12:59:36 PM
Hello All,



Oooo im probably making the "newbe" greeting posting this one ;-)



Im trying to extend a list, now im using 'append or 'cons still the original

variable stays untouched (featured) when i dont use an extra (set 'var ...)



below the example..



> (set 'alist (list '(something)))

((something))



> (set 'alist (cons alist '(hello) ))

(((something)) hello)



> alist

(((something)) hello)



> (set 'alist ( append alist (list '(someone)) ) )

(((something)) hello (someone))



> alist

(((something)) hello (someone))





--- but is it possible to extend a list without the use of the "extra" 'set?

--- so that the original 'list is updated?



like ->



(append alist (list '(to-add)))



or



(cons alist '(new-one))

Norman.

newLISP in the real world / net-listen
February 25, 2004, 11:27:07 AM
I was wondering if its possible to overrule the 'net-listen 'port so that newlisp

is able to bind also to a specific IP, currently it binds to all Addresses,

which is fine ofcourse. So is an extention like (set 'server (net-listen x.x.x.x 12345)) possible ?



My second question (related indirectly to the above)

is how to replace currenlty the (net-local 'port) , which displays

"0.0.0.0" (nth 0 (net-local port)) with something like "12.12.12.12"  (localhost)



A (print (net-lookup (nth 0 (net-local server)))) gives me always 'nil, the

workaround it to place 0.0.0.0 in the /etc/host file.



If a (net-listen 'port) would be able to listen to 'ip the second 0.0.0.0 issue

is automaticly solved.



Just a brain spin...

Hello NigelBrown,



Thanks...happy to be here ;-)



Well some Rebol binary's are for free and also free for commercial use (they did change the policies last year for the (/core) version )

Still im only touched NewLisp for 2 days now but im already porting by Tcl tools to newlisp...like it!

Whither newLISP? /
February 25, 2004, 01:50:15 AM
Hello Lutz,



Thanks again for your information. The linking is very usefull and it works

fine :-) Strange i did not ran into newlisp earlier ;-)

Whither newLISP? / into binary code
February 24, 2004, 02:54:27 PM
Hello Lutz,



I think you had this question already a few times but ill try to hit it again :-)

Although i like intepreters very much sometimes a binary-code could help too..

(its a never ending story ;-) But is there already a wrapper for newLisp or a direct compilation possible from generated code?



Just out of intrest, so dont hit me :-)

Hello Lutz,



Thank you for th intresting reply, gives it a more insight into the world that is called "how to evolve in your own language..." intresting :-)



If your intrested in seeing the overlap that Lisp and Scheme has with rebol

look at http://www.rebol.com/docs/dictionary.html">http://www.rebol.com/docs/dictionary.html, I must say it took me some

weeks to turn around the thinking using rebol but for Lisp guru's and Scheme

lovers it would not be difficult at all, I will stop now talking about rebol..im not

here to promote it, though I see a realy intrest upcoming in the good old

laguages liek Lisp now its more getting mixed with modern interfaces like the internet etc...



Im reading your manual very close;-)



Btw.. do you have ONE good programmers 'hint on 'how to think

during programming using newLisp?



Regards,

Norman.

Hello Lutz,



Thanks for your reply, i assumed something like that already and its good ;-)

Well an overlap in langugaes happens and the "good" parts are always hijacked ;-)



Well ie in rebol (which is strongly based on lisp) a lot of pre build functions

are included (im not speaking of the functional way rebol works because thats

an issue on itself ;-) but like pop:// ftp:// smnp:// http:// tcp:// udp:// for making connections on rfc based protocols is very handy indeed, no wonder

developers run into it ;-)



By the way Is the origin of NewLisp from 1991 already? or when exactly did you start with newlisp?



Regards,

Norman.

Anything else we might add? / newLisp and Rebol
February 23, 2004, 11:44:59 AM
Hello All,



I dont want to start a "yes or no" game :-) Im just currious, I played some years ago with lisp and afterthat fanatic with Tcl and ended up with rebol the last  2 years and that brings me to a spontanious occeurance...



Some Rebol function equal NewLisp or visa versa?

Is this realy an coincidence or is there some Example-Jacking done ?

Its funny to see overlaps though...



Greetings..And ill digg into newLIsp ;-)
