Re: Running compiled Lisp code from command line; using LISP for CGI programming
Hi!
I have two questions to ask. If you know the answer, kindly
post a message here or send me a private reply.
1) COMPILING AND RUNNING COMPILED CODE FROM COMMAND LINE IN
UNIX: I guess the first question is simple. I want to compile
a Lisp function/a set
of Lisp functions and call the compiled code from
command line. I am on a Unix system and I am using
GCL 1.1.
I see that if I compile a file, an
object file is written out, but when I compile a
function, no object file is written out.
Anyway, I compiled a file into its object code
(say file.o) and then tried calling it from
Unix using
%file.o
This obviously is not correct since it core-dumped
on me.
Can someone please tell me what's the way to go about
doing this? How do I specify that the compiled file
needs Lisp to run? How do I specify the name
of the function from among the compiled functions to run?
Please forgive me for my ignorance if these questions
are not properly posed.
2) USING LISP TO CREATE CGI SCRIPTS:
I also want to use Lisp for CGI scripts. I have used
Perl quite a bit for CGI programming, but I am not
sure how to go about doing so with Lisp. I don't
want to use the CL-HTTP server available from MIT. I just
want to use Lisp as a scripting language to a regular
HTTP server and generate a virtual HTML file and
send it back to the browser.
If anyone knows how to go about doing this, kindly
give me some pointers.
Thanks a lot in advance!

I'm curious why you don't want to use the MIT CL-HTTP server. It
provides a nice integration of lisp with HTTP and has the bonus of being
faster than CGI scripts, in part because there is no process start-up
overhead in responding to computed pages. That is because the functions
are already present in the server itself, rather than being invoked as
separate processes. I imagine that this process start-up overhead will
be even worse for anything that first has to start up an entire lisp job
before processing.
In answer to your actual question, I would imagine that you should be
able accomplish your immediate goal once you get a command line
invocation of lisp code functional. Unfortunately I don't know anything
about GCL, so I'll have to leave that to others.

Pass Lisp expressions from the command line. Either your Lisp will
have a parameter "-eval" or esle use
echo '(start-my-compile-frontend "foo")' | lisp

That's how things work in Common Lisp.

In Gcl (and CMUCL), you can't run compiled files directly. You have to
load them into your Lisp image.

The biggest issue is to make your Lisp shut up on stdout if you don't
want to use a wrapper that sends a files written from Lisp. By
default, all Common Lisp are pretty verbose. I have done this for
CMUCL, let me know if you want the code.
You'll still have to write functions to parse QUERY_STRING and friends
yourself.
