Use of \Bold in latex methods, and SageTeX

[John Cremona]

In Sage 7.6:

sage: latex(QQ)
\Bold{Q}

but \Bold is not a standard LaTeX macro. However,

sage: show(QQ)
\newcommand{\Bold}[1]{\mathbf{#1}}\Bold{Q}

shows that the macro is defined somewhere in Sage itself.

Next, if I create a file mini.tex containing

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\title{A Sage\TeX\ document}
The rational field is \sage{QQ}.
\end{document}

and run

pdflatex mini
sage mini.sagetex.sage
pdflatex mini

then the second time pdflatex runs there's an error when it encounters
the undefined \Bold macro. This can be fixed by adding the line
\newcommand{\Bold}[1]{\mathbf{#1}}
into the preamble, but surely this should not be necessary, and there
might be more "missing" macros.

I checked that the version of sagetex.sty being used is exactly the
one in the Sage version I was running.

Hi John,

Within Sage, you can get the appropriate command with


sage: from sage.misc.latex_macros import sage_configurable_latex_macros
sage: sage_configurable_latex_macros
['\\newcommand{\\Bold}[1]{\\mathbf{#1}}']
sage: print(sage_configurable_latex_macros[0])

\newcommand{\Bold}[1]{\mathbf{#1}}

I'm not sure how SageTeX is supposed to handle this, and I'm surprised that it hasn't come up before. The use of \Bold{...} in Sage dates back to 2009: see sage/misc/latex_macros.py.

I am also surprised since I have used SageTeX before without this
problem! In fact I was running it on a tex file which used to work.
On a different computer though...
