broken show for unevaluated integrals

[ma...@mendelu.cz]

Dear sage-devel

the following (definite) integral is not evaluated by maxima and show
() command should return the same unevaluated integral in TeX
notation. I think this was the case in previous versions. On Sage 4.3.
I get th following

input: integrate(1/(1+sqrt(x)),x,0,1).show()

output: \int integrate\,{d \frac{1}{\sqrt{x} + 1}}

expected output: \int_0^1 \frac{..}{...} dx

What has changed?

Hi Robert,

After #7490, we give the function object as the first argument to
custom methods of symbolic functions. The function that prints integrals
is _integrate_latex_() on line 1556 of sage/calculus/calculus.py. It
gets the function integrate as a first argument, and prints the
nonsense you report above.

Here is a ticket:

It should be easy to fix. We should add better error checking and
doctests to the functions though. If no one beats me to it, I can fix
this in the next few days.

Thank you.

Burcin
