6 newlisp - lisp like programming language
7
9 newlisp [-n] [-x source target] [-h | -v] [-c | -C | -http] [-t
10 microseconds] [-s stack] [-m max-mem-megabyte] [[-l path-file | -L
11 path-file] [-p port-number | -d port-number]] [-w directory]
12 [lisp-files ...] [-e programtext]
13
15 Invokes newLISP which first loads init.lsp if present. Then one or more
16 options and one or more newLISP source files can be specified. The
17 options and source files are executed in the sequence they appear. For
18 some options is makes sense to have source files loaded first like for
19 the -p and -d options. For other options like -s and -m it is logical
20 to specify these before the source files to be loaded. If a -e switch
21 is used the programtext is evaluated and then newlisp exits otherwise
22 evaluation continues interactively (unless an exit occurs during
23 lisp-file interpretation).
24
26 -n Suppress loading of any init.lsp or .init.lsp initialization
27 file.
28 -x source target
30 Link the newLISP executable with a source file to built a new
31 target executable.
32 -h Display a short help text.
34 -v Display a version string.
36 -c Suppress the commandline prompt.
38 -C Force prompt when running newLISP in pipe I/O mode for Emacs.
40 -http only accept HTTP commands
42 -s stacksize
44 Stack size to use when starting newLISP. When no stack size is
45 specified the stack defaults to 1024.
46 -m max-mem-megabyte
48 Limits memory to max-cell-mem-megabyte megabytes for Lisp cell
49 memory.
50 lisp-files
52 Load and evaluate the specified lisp source files in sequence.
53 Source files can be specified using URLs. If an (exit) is exe‐
54 cuted by one of the source files then newlisp exits and all pro‐
55 cessing ceases.
56 -e programtext
58 Programtext is an expression enclosed in quotation marks which
59 is evaluated and the result printed to standard out device (STD‐
60 OUT). In most UNIX system shells apostrophes can also be used to
61 delimit the expression. newLISP exits after evaluation of pro‐
62 gramtext is complete.
63 -w directory
65 Directory is the start up directory for newLISP. Any file refer‐
66 ence in a program will refer to this directory by default as the
67 current directory. This can be used to define a web root direc‐
68 tory when in server mode.
69 -l -L path-file
71 Log network connections and newLISP I/O to the file in
72 path-file. -l will only log network connections or commandline
73 input or net-eval requests. -L will additionally log HTTP
74 requests and newLISP output from commandline and net-eval input.
75 -p port-number
77 Listen for commands on a TCP/IP socket connection. In this case
78 standard I/O is redirected to the port specified in the -p
79 option. Any specified lisp-files will be loaded the first time a
80 connection is made, that is, before text is accepted from the
81 port connection.
82 -d port-number
84 Run in demon mode. As for the -p option, but newLISP does not
85 exit after a closed connection and stays in memory listening for
86 a new connection.
87 -t microseconds-connection-timeout
89 Specifies a connection timeout when running in -p or -d demon
90 mode. Server will disconnect when no further input is read after
91 accepting a client connection.
92 -6 Starts newLISP in IPv6 'Internet Protocol version 6' mode. With‐
94 out this switch newLISP willl start in IPv4 mode. The protocol
95 mode can also be switched with the built-in 'net-ipv' function
96 during runtime.
97
99 Start interactive session
100 newlisp
101 Excute a program
103 newlisp myprog.lsp
104 Excute a remote program
106 newlisp http://newlisp.org/example.lsp
107 Add 3 and 4, 7 prints on standard output
109 newlisp -e "(+ 3 4)"
110 newLISP is started as a server (the & indicates to LINUX to run the
112 process in the background) and can be connected to with telnet by issu‐
113 ing telnet localhost 1234
114 newlisp -p 1234 &
115 newLISP is started as a server for another newlisp process connecting
117 with the net-eval function or HTTP requests. Connection timeout is 3
118 seconds.
119 newlisp -c -t 3000000 -d 4711 &
120 newLISP is started as a server handling HTTP requests only. Connections
122 are logged to the file /usr/home/www/log.txt
123 newlisp -l /usr/home/www/log.txt -http -d 8080 &
124 newLISP is started as a server handling HTTP requests and defining the
126 startup/web root directory
127 newlisp -http -d 8080 -w /usr/home/www/httpdocs &
128 When accepting HTTP commands a file httpd.conf can be loaded, which
130 will preprocess the path-name in the HTTP request
131 newlisp httpd.conf -http -d 8080 -w /usr/home/www/httpdocs &
132 If the file httpd.conf contains:
134 (command-event (fn (s)
136 (local (request)
137 (if (find "?" s) ; is this a query
138 (begin
139 (set 'request (first (parse s "?")))
140 ; discover illegal extension in queries
141 (if (ends-with request ".exe")
142 (set 'request "GET /errorpage.html")
143 (set 'request s)))
144 (set 'request s))
145 request) ))
146 then all files ending in .exe will translate the request in to a
148 request for an error page, else the original request string is
149 returned.
150
152 newLISP returns a zero exit status for normal termination unless an
153 exit command specifies a code to be returned. Non zero is returned in
154 case of abnormal exit.
