Leo,
it does not seem to work in the lisp file:
[]$ ~/eng/math/maxima-5.30.0/maxin/bin/rmaxima -q
--init-mac="./tmp/.maxima/maxima-init.mac"
--init-lisp="./tmp/.maxima/maxima-init.lisp"
(%i1) x/y;
(%o1) x/y
(%i2)
Here is the lisp file content:
[]$ cat ./tmp/.maxima/maxima-init.lisp
($load "mathml")
(setf *alt-display2d* (lambda(x) (mfuncall '$mathml x)))
if i start maxima then run an equivalent of the two commands it works
[]$ ~/eng/math/maxima-5.30.0/maxin/bin/rmaxima -q
(%i1) load('mathml) ;
(%o1) /usr/share/maxima/5.27.0/share/contrib/lurkmathml/mathml.lisp
(%i2) :lisp (setf *alt-display2d* (lambda(x) (mfuncall '$mathml x)))
#<FUNCTION (LAMBDA (X)) {1005055CEB}>
(%i2) x/y;
<math xmlns="http://www.w3.org/1998/Math/MathML">; <mi>mlable</mi>
<mfenced separators=""><mfrac><mrow><mi>x</mi> </mrow> <mrow>
<mi>y</mi> </mrow></mfrac> <mo>,</mo><mfrac><mrow><mi>x</mi>
