Sage: Ticket #11428: Customizable latex for functions
https://trac.sagemath.org/ticket/11428
<p>
There should be a way to customize how a function is printed and how it is translated into Latex, as requested on <a class="ext-link" href="http://ask.sagemath.org/question/579/how-to-change-_latex_-of-log-to-ln"><span class="icon"></span>ask-sage</a>.
</p>
<p>
I suggest, as a first step, to add methods <code>set_name()</code> and <code>set_latex_name()</code> that change the value of the cdefined attributes <code>_name</code> used for printing and <code>_latex_name</code> used for translation to latex. Then, the following would work:
</p>
<pre class="wiki">sage: tan.set_name('tg')
sage: tan
tg
sage: tan.set_latex_name(r'\tg')
sage: latex(tan)
\tg
</pre><p>
However, that can really only be the first step. Because, when I did so, I still got
</p>
<pre class="wiki">sage: tan(x)
tan(x)
sage: latex(tan(x))
\tan\left(x\right)
</pre><p>
Hence, in addition to that, the given latex name should be propagated to expressions.

Please upload that preliminary patch so others can work with it!
</p>
<p>
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 :)

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

Patch's up.
</p>
<p>
With it, this works
</p>
<pre class="wiki">sage: tan.set_latex_name(r'\tg')
sage: latex(tan)
\tg
sage: tan.set_name('tg')
sage: tan
tg
</pre><p>
but this doesn't
</p>
<pre class="wiki">sage: tan(x)
tan(x)
sage: latex(tan(x))
\tan\left(x\right)
</pre>

For reference for anyone implementing this correctly, in <a class="ext-link" href="https://groups.google.com/forum/?fromgroups=#!topic/sage-support/wkzIydg95k8"><span class="icon"></span>this thread on sage-support</a>, Burcin recommends
</p>
<pre class="wiki">It needs to go through the
registry of functions stored in Pynac and update the name or the
printing functions there.
