newLISP newS / rapid game prototyping competition
January 27, 2007, 03:23:05 PMNext competition starts Feb 3rd see
Visual basic seems to be a common platform, perhaps prototyping would be even faster with newLisp? and give newLisp a profile in the area - any takers?
I'm not sure what gui framework would be best for this?

newLISP in the real world / capture stderr from (process ...
December 09, 2005, 04:05:04 AMI'm trying porting from python to newlisp (of course) but python has possibility of assigning stderr output to a pipe when starting a process
eg from chatsniff1.0.py -
pipe = Popen('tethereal -i '+str(gDevices.index(gCurrentDevice) + 1)+' -l -V -R "aim || ymsg || msnms || jabber"', bufsize = 1, cwd = path, shell=True, stdin=PIPE, stdout=PIPE, stderr=PIPE, universal_newlines = True)
while (process in newlisp syntax is : (process str-command int-pipe-in int-pipe-out [int-win32-option])
i.e. only stdin stdout directable to pipes.
The code in nl-filesys.c is:
CELL * p_process(CELL * params)
{
char * command;
int forkResult;
int inpipe = 0, outpipe = 0;
params = getString(params, &command);
if(params != nilCell)
{
params = getInteger(params, (UINT*)&inpipe);
getInteger(params, (UINT *)&outpipe);
}
if((forkResult = fork()) == -1)
return(nilCell);
if(forkResult == 0)
{
/* redirect stdin and stdout to pipe handles */
if(inpipe)
{
close(STDIN_FILENO);
if(dup2(inpipe, STDIN_FILENO) == -1) exit(0);
close(inpipe);
}
if(outpipe)
{
close(STDOUT_FILENO);
if(dup2(outpipe, STDOUT_FILENO) == -1) exit(0);
close(outpipe);
}
system(command);
exit(0);
}
could another option after [int-win32-option] be [int-pipe-err]
and newlisp do STDERR_FILENO to pipe?
Or is this not recommended?
Is there another way? - I see in
return value thread (
Lutz:
> (exec "ls *.abc 2>&1")
("ls: *.abc: No such file or directory")
>
The 2>&1 spec tell ls to redirect error output to stdout.
but don't know enough about system() to know if that approach is possible for (process.
Any tips?

newLISP and the O.S. / READLINE in linux vs linux_utf8
November 17, 2005, 12:12:29 PMre rpm building:
Building rpms for 8.7.1 I noted that the makefile for linux disables readline by default viz:
# makefile for newLISP v. 8.x.x on LINUX
#
# Note, that readline support may require different libraries on different OSs
#
OBJS = newlisp.o nl-symbol.o nl-math.o nl-list.o nl-liststr.o nl-string.o nl-filesys.o
nl-sock.o nl-import.o nl-xml.o nl-web.o nl-matrix.o nl-debug.o pcre.o
#CFLAGS = -Wall -pedantic -Wno-uninitialized -c -O2 -g -DREADLINE -DLINUX
CFLAGS = -Wall -pedantic -Wno-uninitialized -c -O2 -g -DLINUX
CC = gcc
whereas the makefile for linux_utf8 has it enabled by default viz:
# makefile for newLISP v. 8.x.x on LINUX with UTF-8 support
#
# Note, that readline support may require different libraries on different OSs
#
OBJS = newlisp.o nl-symbol.o nl-math.o nl-list.o nl-liststr.o nl-string.o nl-filesys.o
nl-sock.o nl-import.o nl-xml.o nl-web.o nl-matrix.o nl-debug.o nl-utf8.o pcre.o
CFLAGS = -Wall -pedantic -Wno-uninitialized -c -O2 -g -DREADLINE -DSUPPORT_UTF8 -DLINUX
CC = gcc
Lutz - how would you like the rpms for download done regarding READLINE?
Note also the needed changes re the spec files:
1.
the .spec files now live in /util instead of /doc so had to change Makefile to
reflect this for rpm and rpm_utf8 sections
2.
new file newlisp/gmp.lsp is not in file list of .spec files so had to add to
.spec file of rpm and utf8 rpm (get warning during rpm build otherwise)

newLISP in the real world / concurrent newlisp ?
March 27, 2005, 12:54:06 AMdiscussing concurrency and lisp and got to thinking.
The current context system could be used to send off a light-weight concurrent process if it
was forbidden to/chose not to access other contexts or if inter-context contact was through
messages.
Perhaps in the future a fork of newlisp rewritten in erlang could be concurrent?
Just thinking out loud.

newLISP in the real world / urpmi newlisp ?
March 24, 2005, 01:57:04 AMIf newlisp was in a mandrake mirror as a contrib or perhaps even plf I could
>urpmi newlisp
and it would be installed. (see
Now we've got the rpms how about going for inclusion into mandrake cooker?
See
How to contribute some packages to Cooker?
First, if you have developed a program and want to make your contribution in the RPM Contribs part of the distribution, please contact the RPM apps manager at
Although I guess this isn't much longer (sorry Lutz I've not installed your key):

Anything else we might add? / 127 char limit in get-url
January 05, 2005, 09:50:44 PMviz:
> (length "
206
trying to get url gives:
> (get-url "
"ERR: bad formed URL"
>
I see in nl-web.c the code:
int parseUrl(char* url, char* host, int* port, char* path)
{
char* colonPtr;
char* slashPtr;
int len;
/* trim trailing whitespace like '/r/n' from url */
if((len = strlen(url)) > 127) return(FALSE);
while(*(url + len) <= ' ' && len > 0)
{
*(url + len) = 0;
len--;
}
...
and
/* parse URL for parameters */
if(parseUrl(url, host, &port, path) == FALSE)
return(stuffString(ERROR_BAD_URL));
...
so I suspect the long url is the problem.
I've not looked further into what would be required to accept longer url's but could this be done easily (in which case I could try coding)? Or would need some string buffer structures etc or different system calls?

newLISP in the real world / flushing thread output
September 20, 2004, 08:58:28 AMI notice that the println output from the multiple threads seems to come out in the order that they are exited rather than the order I would expect if each println printed on the console immediately. See output fragment below.
Is this apparent buffering likely to be in the console output or in the pipes? I'll try some timestamping to check.
However, is there a way to flush output by println to the console immediately? - or does thta always happen? In which case pipe buffering effects seem likely culprits.
I've no experience in this forking stuff!

newLISP and the O.S. / Install & live cd
August 08, 2004, 05:18:44 AMhas OpenMosix clustering 'off the shelf'. I've booted two of my home network
with V3.4 and found openmosix works fine and downloading newlisp source
compiling and running newlisp from the compilation directory works fine as expected.
Run multiple compute intensive newlisp programs and openmosix moves them between the nodes fine!
However, I wanted to use newlsip-tk and found the make install fails because on the 'live cd'
/usr/share is read-only. I tried running newlisp-tk from the ource directory but it
looks for images in the usr/share tree (the default place). I then wanted to change the .config
file for newlisp-tk (as suggested in the docs for running in a different directory)
but you have to be able to start newlisp-tk to generate the first .config
file but I can't start newlisp-tk without a modified .config file?
To get to my point could a default .config file be in the source tree? - it could be in
a few versions for different systems eg .config.linux that could be renamed.
Any other suggestions for running newlisp-tk without images etc being in /usr/share

newLISP in the real world / another C free compiler
June 03, 2004, 09:01:43 PM- now I realise that MS has release a free version (command line only) of Visual C++
viz
"
It's independent of .NET, basically superceeds MSVC++ 6.0. The free package includes all dev tools, libaries and operating system API files, but no graphical front end" - the quote is from
Have you ever tried NewLisp with MSVC Lutz?

However, to be logged in to see if there are new posts since my last vist/check I guess I have to send and receive cookie type info - I've looked around a bit and will look some more but hoped someone may have a quick answer on how to do cookies with newlisp?
