[Maxima-discuss] Saving a \begin{maximasession} ... \end{maximasession} block

[Eduardo O. <edu...@gm...>]

People,

what are your favourite ways to convert a part of a log of a Maxima
session to LaTeX? Let me explain what I did and what I need...

I am on Debian and besides having Maxima installed from the Debian
packages I also have a clone of the git repository of Maxima in the
directory ~/bigsrc/maxima/. I was able to compile EMaximaIntro.tex
with:

  rm -Rv /tmp/emaxima/
  mkdir  /tmp/emaxima/
  cd     /tmp/emaxima/
  cp -v ~/bigsrc/maxima/doc/emaxima/EMaximaIntro.tex .
  cp -v ~/bigsrc/maxima/interfaces/emacs/emaxima/emaxima.sty .
  pdflatex EMaximaIntro.tex
  pdflatex EMaximaIntro.tex

I followed the instructions in the pages 3 and 10 of EMaximaIntro.pdf
and created a .tex file whose important parts were:

  \usepackage{emaxima}
  ...
  \begin{maximasession}
  diff(sin(x),x);
  integrate(cos(x),x);
  \maximaoutput*
  \i5. diff(sin(x),x); \\
  \o5. \cos x \\
  \i6. integrate(cos(x),x); \\
  \o6. \sin x \\
  \end{maximasession}

When I LaTeXed it I got exactly the kind of output that I was looking
for.

My question is: how do I generate a maximasession block like the one
above from inside a Maxima session? Can you recommend me a low-level
way to do that? I normally run Maxima inside Emacs using the low-level
way to send lines to its REPL described here -

I do have Fermin MF's maxima.el installed,

  https://gitlab.com/sasanidas/maxima
  https://emacsconf.org/2020/talks/33/

but I don't understand it well yet, and when I tried to integrate it
with my way of doing things I stumbled on some quirks of its function
`maxima-string'... I tried to ask Fermin for help but he was too busy,
so I thought that it was better to wait until 1) he was in holidays,
2) I had done more of my homework... anyway, I _think_ that I can
handle answers like "use Fermin's functions maxima-foo and maxima-bar"
- and answers that yield a command like

  savemaximasession(42, 99, "/tmp/foo");

that I can run in a Maxima REPL to save the cells 42 to 99 to /tmp/foo
as a maximasession block would be ideal...

  Thanks in advance!!!
