problem with unwanted strikeout in src blocks

problem with unwanted strikeout in src blocks

[Uwe Brauer]

Hi



The following code block is nicely displayed

#+begin_src matlab :exports results :eval never-export :results output latex
disp('P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\')
#+end_src


However when I wrap a solutionorbox around it (which I need when
exporting to latex) all text between the «+» 
gets a strikeout.


#+begin_solutionorbox
#+begin_src matlab :exports results :eval never-export :results output latex
disp('P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\')
#+end_src
#+end_solutionorbox

And idea what to do?

Thanks

with R I can to the following.

cat("\\begin{align*}")
cat("P(\\text{Covid19}|\\text{ + })&=\\frac{P(\\text{ + }|\\text{Covid19})P(\\text{Covid19})}{P(\\text{ + } | \\text{Covid19})P(\\text{Covid19}) + P(\\\\text{ + }|\\text{No-Covid19})P(\\text{No-Covid19})}")
cat("\\end{align*}")
#+end_src

With the :post keyword so that you can wrap pretty much anything. 

(info "(org) Results of Evaluation")

Consider

#+NAME: box
#+BEGIN_SRC emacs-lisp :var equation="" 
(format  "\\\\begin{solutionorbox}
 %s
 \\\\end{solutionorbox}" equation )
#+end_src


#+begin_src R :exports results  :eval yes  :results output latex :post box(*this*)
cat("\\frac{3}{4}")
#+end_src  

#+RESULTS:
#+begin_export latex
\\begin{solutionorbox}
 \frac{3}{4}
 \\end{solutionorbox}
#+end_export

HTH,

This is a known bug in Org fontification. The fix is not trivial. WIP.
See https://orgmode.org/list/87ee7c9quk.fsf@localhost

Current development version of the fix is in
https://github.com/yantar92/org/tree/feature/org-font-lock-element, but
it is not yet complete and will require a lot more work.

Note that other than the visual appearance, your code block is not
affected. That is, export will work just fine. No strike-through will
be present.

Best,
Ihor

Aha, thanks!

Ok right now this is not so important for me. I might give it a try some
other time, just for testing proposes.

That I assumed already, still it is a bit annoying, but then not that
important I say.

Yes but I need the solutionbox since I don't want to convert to vanilla latex, but to the exam class.
