This works:
sage: maxima_calculus.load('to_poly_solve')
\"/usr/local/sage/sage-git/local/share/maxima/5.35.1/share/to_poly_solve/to_poly_solve.mac\"
whereas this does not:
sage: maxima_calculus.load('to_poly_solve.mac')
TypeError: ECL says: In function PATHNAME, the value of the only argument is
((MNCTIMES SIMP) $TO_POLY_SOLVE $MAC)
which is not of the expected type (OR FILE-STREAM STRING PATHNAME)
(clearly, the filename is parsed rather than taken as a string)
This does seem to work:
sage: maxima_calculus.load('"to_poly_solve.mac"')
\"/usr/local/sage/sage-git/local/share/maxima/5.35.1/share/to_poly_solve/to_poly_solve.mac\"
as does this:
sage:
maxima_calculus.load('"/usr/local/sage/sage-git/local/share/maxima/5.35.1/share/to_poly_solve/to_poly_solve.mac"')
\"/usr/local/sage/sage-git/local/share/maxima/5.35.1/share/to_poly_solve/to_poly_solve.mac\"
so it looks like there's nothing particularly wrong with the load command
once you let it deal with strings properly.
If you want to take it a little closer to the metal you can do
sage: maxima_calculus._eval_line('load("to_poly_solve.mac")')
'\\"/usr/local/sage/sage-git/local/share/maxima/5.35.1/share/to_poly_solve/to_poly_solve.mac\\"
which seems to work as well.
Working with a nonexisting file gives a rather uninformative error message:
sage: maxima_calculus.load('"blah.mac"')
TypeError: ECL says: Error executing code in Maxima:
whereas maxima tells exactly what goes wrong. So the error message
capturing technology can perhaps be improved.
