[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.

Best,
Leo

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.

9.5.5-g5bc674, I just pulled it, rebuilt and works properly (without plots)
