NAME
       newlisp - lisp like programming language

SYNOPSIS
       newlisp  [-h]  [-c  |  -C | -http] [-s stacksize] [-m max-mem-megabyte]
       [[-l path-file | -L path-file] [-p port-number | -d  port-number]]  [-w
       diectory] [lisp-files ...] [-e programtext]

DESCRIPTION
       Invokes newLISP which first loads init.lsp if present. Then one or more
       options and one or more newLISP source  files  can  be  specified.  The
       options  and source files are executed in the sequence they appear. For
       some options is makes sense to have source files loaded first like  for
       the  -p  and -d options. For other options like -s and -m it is logical
       to specify these before the source files to be loaded. If a  -e  switch
       is  used  the programtext is evaluated and then newlisp exits otherwise
       evaluation  continues  interactively  (unless  an  exit  occurs  during
       lisp-file interpretation).

OPTIONS
       -h     Display a short help text.

       -c     Suppress the commandline prompt.

       -C     Force prompt when running newLISP in pipe I/O mode for Emacs.

       -http  only accept HTTP commands

       -s stacksize
              Stack  size  to use when starting newLISP. When no stack size is
              specified the stack defaults to 1024.

       -m max-mem-megabyte
              Limits memory to max-mem-megabyte megabytes for LISP  cell  mem-
              ory.

       lisp-files
              Load  and  evaluate the specified lisp source files in sequence.
              Source files can be specified using URLs. If an (exit)  is  exe-
              cuted by one of the source files then newlisp exits and all pro-
              cessing ceases.

       -e programtext
              Programtext is an expression enclosed in quotation  marks  which
              is evaluated and the result printed to standard out device (STD-
              OUT). In most UNIX system shells apostrophes can also be used to
              delimit  the  expression. newLISP exits after evaluation of pro-
              gramtext is complete.

       -w directory
              Directory is the start up directory for newLISP. Any file refer-
              ence in a program will refer to this directory by default as the
              current directory. This can be used to define a web root  direc-
              tory when in server mode.

       -l -L path-file
              Log   network  connections  and  newLISP  I/O  to  the  file  in
              path-file. -l will only log network connections  or  commandline
              input  or  net-eval  requests.  -L  will  additionally  log HTTP
              requests and newLISP output from commandline and net-eval input.

       -p port-number
              Listen  for commands on a TCP/IP socket connection. In this case
              standard I/O is redirected to  the  port  specified  in  the  -p
              option. Any specified lisp-files will be loaded the first time a
              connection is made, that is, before text is  accepted  from  the
              port connection.

       -d port-number
              Run  in  demon  mode. As for the -p option, but newLISP does not
              exit after a closed connection and stays in memory listening for
              a new connection.


EXAMPLES
       Start interactive session
              newlisp


       Excute a program
              newlisp myprog.lsp


       Excute a remote program
              newlisp http://newlisp.org/example.lsp


       Add 3 and 4, 7 prints on standard output
              newlisp -e "(+ 3 4)"


       newLISP  is  started  as  a server (the & indicates to LINUX to run the
       process in the background) and can be connected to with telnet by issu-
       ing telnet localhost 1234
              newlisp -p 1234 &


       newLISP  is  started as a server for another newlisp process connecting
       with the net-eval function or HTTP requests
              newlisp -c -d 4711 &


       newLISP is started as a server handling HTTP requests only. Connections
       are logged to the file /usr/home/www/log.txt
              newlisp -l /usr/home/www/log.txt -http -d 8080 &


       newLISP  is started as a server handling HTTP requests and defining the
       startup/web root directory
              newlisp -http -d 8080 -w /usr/home/www/httpdocs &

       When  accepting  HTTP  commands  a file httpd.conf can be loaded, which
       will preprocess the path-name in the HTTP request
              newlisp httpd.conf -http -d 8080 -w /usr/home/www/httpdocs &

       If the file httpd.conf contains:

       (define (httpd-conf path-name)
           (if (ends-with path-name ".exe") "errorpage.html" path-name))

       then  all  files  ending  in  .exe  will  translate the request in to a
       request for  an  error  page,  else  the  original  request  string  is
       returned.


EXIT STATUS
       newLISP  returns  a  zero  exit status for normal termination unless an
       exit command specifies a code to be returned. Non zero is  returned  in
       case of abnormal exit.
