Hi Leo, The first suggestion, to add to org-babel-maxima--output-filter-regexps does fix the src block you ask about here. However, the regexp doesn't match for other maxima tests. For example:
#+name: ob-maxima/batch+verbatim #+begin_src maxima :results verbatim :batch batch :cmdline --quiet (assume(z>0), integrate(exp(-t)*t^z, t, 0, inf)); #+end_src #+RESULTS: ob-maxima/batch+verbatim #+begin_example (%i1) (linenum:0, (%i1) (assume(z > 0),integrate(exp(-t)*t^z,t,0,inf)) (%o1) gamma(z + 1) #+end_example Best, Ben On Wed, Dec 11, 2024 at 7:02 AM Leo Butler <leo.but...@umanitoba.ca> wrote: > On Tue, Dec 10 2024, Benjamin McMillan <mcmilla...@gmail.com> wrote: > > > Hi Leo, > > I get the following output: > > > > #+RESULTS: > > > > #+begin_example > > (linenum:0, > > #+end_example > > > > and from *messages*: > > > > Executing Maxima source code block > > maxima -r \(linenum\:0\,\ > > > batchload\(\"/var/folders/f5/6nrph1812wdf0nlg4ddcs_580000gn/T/babel-wImUPJ/maxima-Swf2M2.max\"\)\)\$ > > --very-quiet > > Wrote > > > /var/folders/f5/6nrph1812wdf0nlg4ddcs_580000gn/T/babel-wImUPJ/ob-input-Rbgtzp > > Code block evaluation complete (took 0.1s). > > > > The contents of that file (which I also attach) are: > > > > build_info(); > > > > If there's more information I can give, just let me know. > > Thanks, > > Benjamin > > > > On Tue, Dec 10, 2024 at 9:17 AM Leo Butler <leo.but...@umanitoba.ca> > wrote: > > > >> On Mon, Dec 09 2024, Leo Butler <leo.but...@umanitoba.ca> wrote: > >> > >> > On Sun, Dec 08 2024, Ihor Radchenko <yanta...@posteo.net> wrote: > >> > > >> >> Benjamin McMillan <mcmilla...@gmail.com> writes: > >> >> > >> >>> This outputs > >> >>> #+RESULTS: > >> >>> | (linenum:0, | > >> >>> | 4 | > >> >>> > >> >>> I suppose the issue is the "linenum:0".
