Error: NIL is not a number

[Brian]

Hi,

I've just set up fomus on cygwin (clisp, cm) but I'm having a little
trouble getting it working.

I'm just trying the first example in the docs as listed below but
I get an error message: "*** - -: NIL is not a number".

I know this is a pretty common Lisp error (excuse the unintentional pun!)
but I'm not sure where I should be looking to resolve it.

Any suggestions would be very much appreciated.

Thanks a million,
Brian


This is the example code:
-------------------------

(fomus
:output '(:lilypond :view t)
:ensemble-type :orchestra
:parts
(list
(make-part
:name "Piano"
:instr :piano
:events
(loop
for off from 0 to 10 by 1/2
collect (make-note :off off
:dur (if (< off 10) 1/2 1)
:note (+ 48 (random 25))
:marks (when (<= (random 3) 0)
'(:staccato)))))))



This is the error message I'm getting
(including some initial startup warnings):

Brian,

I made an attempt a while ago to get fomus working in CLISP but didn't
quite get all the bugs worked out--so unfortunately it might take a
little time to solve this. :( There are a few things that CLISP is
picky about that work fine in all the other Lisps. I'll take a look at
it and try to get an update out shortly.

Most of the CLISP issues should be worked out--I haven't tested it in
Windows yet (only Linux), so another update might come shortly

Moved the project to subversion--(there's no "dev" branch anymore, just
the main one, plain and simple)

Admin initial checkout would look something like this:

mkdir fomus
svn checkout
svn+ssh://<username>@common-lisp.net/project/fomus/svn/fomus/trunk fomus

mkdir fomustest
svn checkout
svn+ssh://<username>@common-lisp.net/project/fomus/svn/fomustest/trunk
fomustest

After that if you haven't used subversion before it's very similar to
CVS ("SVN update", etc..). Sorry for the confusion--this is what I'll
stick to now.

"Stable" releases will still be wrapped up in tarballs and deposited on
the web site for download.
