[babel] Maxima code blocks do not work

[babel] Maxima code blocks do not work

[Bernd Weiss]

Dear all,

The follwing Maxima code block does not work:

#+begin_src maxima
1+1;
#+end_src

#+results:
#+begin_example
incorrect syntax: / is not a prefix operator
incorrect syntax: GuM is not an infix operator
parser: incomplete number; missing exponent?
 -- an error. To debug this try: debugmode(true);
incorrect syntax: Too many )'s
incorrect syntax: Premature termination of input at $.
Maxima encountered a Lisp error:
 parser: end of file while scanning expression.
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.
#+end_example


Thanks,

Bernd

Strange.  I don't get this at all.  In fact, I get no output at all with
your example.  If I change the code to:

#+begin_src maxima
a: 1+1;
print(a);
#+end_src

then I get:

#+results:
: 2

I am running a newer version of org than you are so maybe update?  I am
also on emacs 24.

HTH,
eric

Hi Eric,

Thanks for your answer!

I updated org (again, now it's Org-mode version 7.5
(release_7.5.461.g6d18)), I switched to Emacs 24 but to no avail. I also
tried to use the debugger but this does not seem to be an error...

Debug on Error enabled globally
executing Maxima code block...
executing Maxima source code block
maxima --very-quiet -r
'batchload("c:/Users/weiss/AppData/Local/Temp/babel-209000BH/maxima-20900VN1")$'
nil
Code block evaluation complete.

I also realized that the 'error message' changes every time I try to run
the code block:

#+results:
: incorrect syntax: / is not a prefix operator
: incorrect syntax: aLH is not an infix operator
: incorrect syntax: hCp is not an infix operator
: incorrect syntax: Premature termination of input at $.
: Maxima encountered a Lisp error:
:  parser: end of file while scanning expression.
: Automatically continuing.
: To enable the Lisp debugger set *debugger-hook* to nil.

This message is 'related' (see lines 3 "aLH is not an infix operator"
and 4 "hCp is not an infix operator") to the following Maxima call
("aLH/maxima-17716hCp"):

maxima --very-quiet -r
'batchload("c:/Users/weiss/AppData/Local/Temp/babel-17716aLH/maxima-17716hCp")$'
nil

Unfortunately, my elisp knowledge is too low to understand what's going
on in ob-maxima.el. Is it a MS-Windows-thing ('/' vs '\')?

To be honest, running Maxima in org in not so important for me. As long
as R works, everything is fine :-)

Thanks,

Bernd

The error messages look like maxima is trying to evaluate the actual
string within double quotes!

Good question. Has anybody else used maxima with org babel on Windows?
I don't even have such a system to try...  

My guess would be that the "shell" command required to invoke maxima on
Windows needs to be significantly different than what we are using here
(which works on Linux).  Then again, I've never really used Windows
(beyond starting Word on somebody else's document on somebody else's
machine... ;-) so I don't have a clue what Windows expects...

Hi Eric,

Again, thanks a lot for your help!

Okay, it definitely is a Windows problem. If I run the following command
in a cygwin shell, everything works as expected:

maxima --very-quiet -r
'batchload("c:/Users/weiss/AppData/Local/Temp/babel-17716aLH/maxima-17716hCp")$'
nil

However, it does not work in a Windows shell. But this is no longer an
org issue.

Actually, it is still an org issue, albeit one which requires input from
those with much more Windows knowledge than I have.  It's an org issue
because I think we do (or should) strive to have org, as a whole, work
on any system that runs Emacs?  

There are only two arguments to the maxima invocation above:
=--very-quiet= to minimise the amount of superfluous output and =-r= to
ask maxima to execute the following maxima command ("batchload(...)")
which is what tells maxima to execute commands from the file that babel
creates.

If you (anybody) can figure out the magic incantation necessary to
invoke maxima on Windows and have it execute commands from a file, it
should be straightforward to upgrade the =ob-maximal.el= file to use the
right incantation depending on the operating system.
