Description
There should be a way to customize how a function is printed and how it is translated into Latex, as requested on ask-sage.
I suggest, as a first step, to add methods set_name()
and set_latex_name()
that change the value of the cdefined attributes _name
used for printing and _latex_name
used for translation to latex. Then, the following would work:
sage: tan.set_name('tg') sage: tan tg sage: tan.set_latex_name(r'\tg') sage: latex(tan) \tg
However, that can really only be the first step. Because, when I did so, I still got
sage: tan(x) tan(x) sage: latex(tan(x)) \tan\left(x\right)
Hence, in addition to that, the given latex name should be propagated to expressions.

Preliminary patch: Change latex/repr of a function. But the custom names are not propagated.

Patch's up.
With it, this works
sage: tan.set_latex_name(r'\tg') sage: latex(tan) \tg sage: tan.set_name('tg') sage: tan tg
but this doesn't
sage: tan(x) tan(x) sage: latex(tan(x)) \tan\left(x\right)

For reference for anyone implementing this correctly, in this thread on sage-support, Burcin recommends
It needs to go through the registry of functions stored in Pynac and update the name or the printing functions there.

Please upload that preliminary patch so others can work with it!
The SR stuff does come from Ginac, as I thought I remembered. Maybe Burcin will have a brief comment to put us on the right track for that; I don't quite understand how it works, though I think I once nearly figured it out :)
