FYI;
I think the Latex code generated by Fricas here might not be valid. But I
am not sure.
But it hangs Lualatex when I compile it and when I am using breqn package.
Here it is
------------------------
ii:=integrate(1/(a^2-b^2*x^2), x)
tex(ii::OutputForm::TexFormat)
[
"{{\log \left( {{{b \ x}+a}} \right)} -{\log \left( {{{b \ x} -a}}
\right
)}} \over {2 \ a \ b}"
]
------------------------
Now I put the above code in a latex file and compile it:
\documentclass[]{article}\usepackage{amsmath}\usepackage{breqn}\begin{document}
\begin{dmath*}[frame={.5pt}]{{\log \left( {{{b \ x}+a}} \right)} -{\log \left(
{{{b \ x} -a}} \right)}} \over {2 \ a \ b}\end{dmath*}
\end{document}
Using lualatex foo.tex
This seems to hangs or crashes lualatex. amsmath does not like the latex
code and gives warning
Package amsmath Warning: Foreign command \over;(amsmath) \frac
or \genfrac should be used instead(amsmath) on input line 8.
May be \over can be replaced by \frac ?
I posted this question
at
https://tex.stackexchange.com/questions/412450/why-this-latex-code-hangs-lualatex-foreign-command-over
asking for workaround.
Thanks
