hallo world in lisp

[Luciano Ribichini]

hallo,
I use Linux (kernel 2.2.x)
I would like to try the LISP language.

Can you tell me where to find a free/GLP lisp (interpreter, compiler or
what else )
and how to run the lisp variant of the famuos hallo world! c-program ?

Thanks
Luciano

CMUCL, CLISP, the free versions of commercial product (LispWorks, ACL,
MCL and probably some more)

(print "Hello World")

On the off chance that you are running Debian: CMUCL and CLISP are
included in the distribution.

Enjoy!

This might be a good starting point:

http://ww.telent.net/cliki/Common%20Lisp%20implementation

or this:

http://clisp.sourceforge.net/

This will not teach you much, I'm afraid, but here you are:

(format t "~&Hello World!~%")

Here's a link on Lisp books, some of which can be gotten off the net:

cheers,
Erik

Which distribution?

Good!

If you use Debian GNU/Linux, just apt-get install cmucl or clisp.

The famous C program is famous for its ablity to produce an executable
with a minimal amount of fuss. It really shows off the Unix environment,
and not the language. However, an executable is only a funtcion that
resides on disk in the Unix file sysem and which you call from the
shell's read-execute interactive loop. Common Lisp systems offer their
own interactive loop, called the read-eval-print loop and do not
generally take part in the shell interactive loop the same way other
languages do. Some find this a insurmountable obstacle to using Common
Lisp, others love it. However, the code for the core program is simple:

(defun hello-world ()
(write-line "Hello, Lisp world!"))

Suppose you put this in a file, hello.cl. To compile it, evaluate

(compile "hello.cl")

You now have an object file that can be loaded into the Common Lisp
system:

(load "hello")

You are now ready to execute the hello-world function:

(hello-world)

If you want to run an "executable" from the shell interactive loop, there
are many ways to accomplish this, but no standard way. Suppose you use
CLISP and have a Linux kernel with misc-binaries support you can do this,
as root:

echo ":CLISP:E::fas::/usr/bin/clisp:" >> /proc/sys/fs/binfmt_misc/register
echo ":CLISP:E::lisp::/usr/bin/clisp:" >> /proc/sys/fs/binfmt_misc/register

You can now actually just write

(write-line "hello, Lisp world!")

into the file hello.lisp and chmod +x hello.lisp and execute it directly.
Note that you would have to add (hello-world) at the end of the hello.cl
file I indicated above to execute anything.

Thanks Eric, that's new for me. Well that' really nice. And it works
like a charm.

Couple of (perhaps a bit strange) lisp interpreters may also have sneaked
into your system already - emacs and rep.
