Comment(by SimonKing):
I thought that the improvements to sageinspect from #9976 would make
things robust enough, so that sage_getfile could be used to extract the
information on where to import stuff from.
But with or without #9976, we have
{{{
sage: P.<x,y> = QQ[]
sage: P??
Error getting source: could not find class definition
...
Docstring [source file open failed]:
File: sage/rings/polynomial/multi_polynomial_libsingular.pyx (starting
at line 229)
Construct a multivariate polynomial ring subject to the following
conditions:
INPUT:
* ``base_ring`` - base ring (must be either GF(q), ZZ, ZZ/nZZ,
QQ or absolute number field)
* ``n`` - number of variables (must be at least 1)
* ``names`` - names of ring variables, may be string of list/tuple
* ``order`` - term order (default: ``degrevlex``)
}}}
The "Error getting source: could not find class definition" is annoying.
Note that the doc string above gives the correct location and line number!
So, sage.misc._extract_embedded_position should be able to do the job, but
it isn't.
I think improving the introspection further should be on a different
ticket, on top of #9976.
Cheers,
Simon
