Custom definitions for latex style

[sagetrac-schymans]

#6290 introduced a way to custom-define the latex style of functions, but it would be great if something similar was made possible for any variable. I used to do it in the following way, but now I get an error message:

sage: var('hi kunsati delyui')

sage: hi.latex = lambda: 'h_i'

sage: kunsati.latex = lambda: 'K_{unsat,i}'

sage: delyui.latex = lambda: '\delta_{yu,i}'

Traceback (most recent call last):

...

AttributeError: 'sage.symbolic.expression.Expression' object attribute 'latex' is read-only

Comment by Burcin Erocal on sage-devel (25/06/2006):

Since Expression is a cython class, you cannot overwrite the latex() method.

Pynac supports setting latex names for variables at creation, but this functionality is not exposed in the wrapper. Another solution by hacking latex_variable_name() might be possible, but I would like to avoid that if possible.

Feel free to open a new issue in trac about it.

Cheers,
Burcin

How could the Pynac funtionality of setting latex names for variables at creation be exposed?

Supposedly, the patch for #6559 fixes this (see comment added to description). Could you review #6559 instead? Thanks!

I'm closing this, since #6559 just got merged. It adds a latex_name keyword argument to var(), which is the functionality requested here.
