Thanks Mike, it was very helpful. I have now mostly ported the old
patch (#5711) to new symbolics. Consequently, typesetting for "integrate",
"diff", "limit", "laplace", "inverse_laplace", symbolic functions (Greek
letters) are working great in sage-4.0.1.
However, there are couple of issues that I need to sort out.
(1) In "py_latex_function_pystring" function (sage.symbolics.pynac),
what does the argument "fname_paren" signify? Why does typesetting
depend on it?
(2) keyword "latex_name": If I understand correctly, the new
"SFunction" class can be given keyboard argument
"latex_name=LaTeX". Somehow, it doesn't seem to work
from notebook. It would be really cool if we could define a
symbolic function as
----
riemann(x) = function('riemann', x, latex_name="\\mathcal{R}")
----
(3) Is there an equivalent class for "SymbolicVariable" in new symbolics?
If yes, then certain customization can be done. For example, f(x) can
be typeset as "f(x)" whereas f(x^2) can be typeset as "f\left(x^2\right)".
(4) Should we switch to old maxima format for "diff"?
Cheers,
Golam
