[O] Maxima code blocks does not work in windows revisited

[Mati]

Ok, I got it working somehow. For others reading this: I had to modify 
~/.emacs.d/straight/repos/org/lisp/ob-maxima.el in emacs(!) so straight 
compiled it to work. you need to replace code at line 82. However, plots 
still doesn't work (code block produced no output) :( pls help.

Do you mean that you changed the code at line 82 inside
org-babel-execute:maxima to

 (let* ((cmdline (or (cdr (assoc :cmdline params)) ""))
	  (in-file (org-babel-temp-file "maxima-" ".max"))
		(cmd (format "%s --very-quiet -r \"batchload(\\\"%s\\\")$\" %s"
			     org-babel-maxima-command in-file cmdline)))

??

yes, of course only part of it


I am testing maxima-mode now (not in org) and it works, but is broken on 
windows. Looks like there are many more problems with syntax.

Please don't make people guess at what you have done. Ihor, in
particular, does a huge amount of work on Org. Making him and us guess
only makes that work harder.

I am interested to know what is broken in maxima-mode. Please
explain with examples.

There is problem with handling ghostscript. Ghostscript gui opens three 
times, one time with commands help, and error is displayed in 
minibuffer: "Your version Ghostscript does not appear to support the 
image type -sDEVICE=png16m. The command "gs -h" lists the available 
devices." when it does support it. maybe if I could use setup file it 
would work, but it gives error: Wrong type argument: stringp, nil. I 
also had to correct miktex path in this function, but without 
modification this error occurs too

Overall, configuration on windows is a pain. manually installing 
packages in miktex and ghostscript (not that bad, but I had to dig to 
find that's neccesary), wondering what code actually should be put in 
init.el, finding and moving files from maxima installation to site-lisp, 
adding installation pathes to path environment variable because 
setup-imaxima-imath.el is not working...

Plots produce output but it's not inline in emacs buffer, but gnuplot 
window.

My current path to miktex binary is: 
C:\Users\user\AppData\Local\Programs\MiKTeX\miktex\bin\x64

My init.el config for maxima:

Ok. Does the attached patch work for you?

Org support for Maxima does not require maxima-mode to be installed,
except for optional fontification.

Note that we can only help with within Org scope. We cannot freely modify
Maxima code.

It will be more productive if you contact Maxima developers on the
issue. They do have a mailing list:
https://maxima.sourceforge.io/maximalist.html#discussion

Re: [O] Maxima code blocks does not work in windows revisited

Ok, I tried this patch, but now when I try to eval maxima code it 
outputs similar broken table:

| incorrect | syntax: | c | is | not | an | infix | operator |
| ^        |        |   |   |     |    |      |         |

Plots have no output as before.

To clarify, previous patch worked except plots. And of course I applied 
patch to fresh org repo downloaded with straight.el

Could you please describe what exactly you tried, what you expected, and
what you got?

My patch should be equivalent to originally proposed, but
I am not exactly sure what you have applied on your side. And I have no
idea which table you are talking about.

Ihor, you recently applied an alternative patch to Org main branch. 
Emacs tree still has ob-maxima.el with single quotes around batchload.

Notice that code in the message you cited has "%s" and does not have 
`shell-quote-argument'. Extra quotes may discard effect of existing 
double pass escaping.

Really robust solution require a dedicated maxima option that allows to 
pass file name as a separated argument instead of a part of expression,

Yes, OP should try this solution first. If it fails, then there is
some problem in `shell-quote-argument' that needs to be fixed.

To be clear. I believe that Mati should try the code from the Org "main" 
branch, not the patch Ihor posted in this thread. If I got it correctly, 
Mati currently has some problems with plots, ghostscript, etc.

Is there anything wrong with the following command (I am unsure 
concerning Temp location)? If so, what is the proper escaping for 
cmd.exe+maxima?

(let ((system-type 'ms-dos)
       (org-babel-maxima-command "maxima")
       (in-file "c:\\Temp\\maxima-XXXXXX.max")
       (cmdline ""))
   (message
    "%s"
    (format "%s --very-quiet -r %s$ %s"
	   org-babel-maxima-command
	   (shell-quote-argument
	    (format "batchload(%S)" in-file))
	   cmdline)))

maxima --very-quiet -r "batchload(\"c:\\Temp\\maxima-XXXXXX.max\")"$

(there is a trailing space)

Does "$" have any special meaning in cmd.exe? I do not mind that it 
should be inside `format' first argument.

I do not have a Windows machine to test and not motivated enough to try 
Emacs in wine.

P.S. To avoid tricky escaping I strongly prefer direct exec to shell 
commands. Unfortunately as soon as TRAMP is involved, shell is the only 
option. Ssh supports command strings only and passes them to shell.

Max, a minor modification of the test you sent earlier shows that when
system-type is ms-dos, the placement does not matter (the command-line
is the same); but for gnu/linux, placement matters and Eric is right
(the command-lines are not the same and the dollar sign needs to be
escaped).

I have attached a patch that puts the dollar sign in the right place for
both. The existing tests pass when running 'make test'.

Thanks for pointing this out!
I do not use Windows, so it is hard to check how things are there. I
assumed that the report herein is not the latest main, which may or may
not be the case.

Maxima code blocks does not work in windows revisited

[Juan Alvaro Fuentes]

[-- Attachment #1: Type: text/plain, Size: 1688 bytes --]

Dear all,

It seems that maxima code blocks still does not work in windows as the
following code did not work when I tried to run it:

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

This is an old issue already emailed to this emacs org-mode list in an
email dating from june 2011.

The conversation ended up with a final reflection which I copy next:

>* 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")$'*

Trying to find the correct string that makes maxima execute the batch
file in windows I found that this command does work:

maxima --very-quiet -r
"batchload(\"c:/Users/alvaro/AppData/Local/Temp/babel-7740OHt/maxima-7740OpY.max\")$"

maxima --very-quiet -r
"batchload(\"c:/Users/alvaro/AppData/Local/Temp/babel-7740OHt/maxima-7740OpY.max\")$"

2


I tried to make this string when maxima is executed in the shell and
modifying ob-maxima.el found that this seems to work for windows 8,
emacs 24.4 and org 8.2.7b:


 (let* ((cmdline (or (cdr (assoc :cmdline params)) ""))
          (in-file (org-babel-temp-file "maxima-" ".max"))
		(cmd (format "%s --very-quiet -r \"batchload(\\\"%s\\\")$\" %s"
			     org-babel-maxima-command in-file cmdline)))


The problem is that my lisp skills are not very good, to say the
least, and sending a patch is one more problem so I write this email
if this can help anybody to makemaxima code blocks work in windows.


Thanks,

Juan Alvaro

I don't have a machine with Windows so I can't really help here, but I
hope an Org/Maxima/Windows user can help debugging this further.

Best,
