Try
sage: latex.add_macro("\\newcommand{\\foo}{bar}")
(just like in the examples in the documentation).
Thanks. I guess I got confused by the imports in the documentation
and didn't realize that latex wasn't sage.misc.latex...
But (and hopefully this is just another simple misunderstanding)
I still don't quite get it. In the worksheet is accepts:
latex.add_macro("\\newcommand{\\foo}{bar}")
and latex.extra_macros() returns:
'\\newcommand{\\foo}{bar}'
So, I expected that I could now do: html('$\\foo$')
But I just get 'Unknown control dequence '\foo'
I'm starting to think that perhaps I'm confused about
the relationship of latex and jsMath. Maybe I'm not
on the right track at all. What I'm trying to do it
to be able to define (what I think of as) a "latex macro"
so that I can use it in a sage worksheet. Not in a
%latex cell, but in a regular sage cell. I.e., I
want to be able to say: html('$\\foo$') in the
middle of my normal sage code in the worksheet.
For example, to make this work for a "regular" web
page, I would put the macro definition in someplace
like /var/www/html/jsMath/easy/load.js and then on
the webpage do:
<script src="http://localhost/jsMath/easy/load.js";></script>
