The SymPy printing is not activated unless your class subclasses from
Basic. If you won't want to do that, the best way to make your object
print with LaTeX in the notebook is to just use the IPython machinery:
class Test:
def _repr_latex_(self):
return r"$$\LaTeX$$"
If all you want is an object that displays LaTeX, you can just use
IPython.display.Math.
If you do subclass from Basic, it would look like this
class Thing(Basic):
def _latex(self, p):
return r"\LaTeX"
Two notes
- _repr_latex_ requires the $; _latex does not.
- _latex takes a second argument, which is the LaTeX printer. You
should use this to dispatch printing of subobjects. You can also use
it to get the options that have been set on the LaTeXPrinter and print
accordingly (e.g., inline vs. equation).
