Comment (by was):
The design of "typeset mode" in sagenb isn't so good in my opinion. For
the record, I've implemented something similar for
https://cloud.sagemath.com, which correctly handles the above problem in
an extensible way. Here's the *complete* code for the entire thing:
{{{
_system_sys_displayhook = sys.displayhook
import sage.misc.latex, types
TYPESET_MODE_EXCLUDES = (sage.misc.latex.LatexExpr, types.NoneType)
def typeset_mode(on=True):
"""
Turn typeset mode on or off. When on, each output is typeset using
LaTeX.
EXAMPLES::
typeset_mode() # turns typesetting on
typeset_mode(False) # turn typesetting off
"""
if on:
def f(obj):
if isinstance(obj, TYPESET_MODE_EXCLUDES):
_system_sys_displayhook(obj)
else:
salvus.tex(obj)
sys.displayhook = f
else:
sys.displayhook = _system_sys_displayhook
}}}
