The index.rst file below demonstrates that \newcommand does not work with
latexpdf.
------------ Below is my conf.py file ------------------------

Problem With \newcommand in latexpdf
####################################
This file builds just file,
and displays as intended, with ``make html``,
but with ``make latexpdf`` it generates and
``Undefined control sequence.`` error for the
macro ``\B``.
Define Latex Macro
******************
``:math: \newcommand{\B}[1]{{\bf #1}}``
:math:`\newcommand{\B}[1]{{\bf #1}}`
Use Latex Macro \B
******************
``:math: f : \B{R} \rightarrow \B{R}``
:math:`f : \B{R} \rightarrow \B{R}`
the LaTeX has scope limiting constructs such as "environments"
but also equations, inclusive of inline mathematics
(delimited in the file in LaTeX mark-up produced by make latex by \( ... \)
delimiters)
you must locate the \newcommand outside of such scope delimited location
either via
.. raw:: latex
\newcommand{\B}[1]{{\bf #1}}
before it is used (and only once)
or in conf.py
latex_elements = {
'preamble': r"\newcommand{\B}[1]{{\bf #1}}",
}
which is a priori better location, recommended for that usage.
Once this is done do not put any other \newcommand{\B} as this will generate an
error.
Notice that \bf mark-up has been deprecated by LaTeX developers
and perhaps {\mathbf{#1}} is more legit
latex_elements = {
'preamble': r"\newcommand{\B}[1]{\mathbf{#1}}",
}
or, if you use xelatex with unicode-math, perhaps \symbf
Besides LaTeX normative gurus will try to discourage you to define a one-letter
command such as \B. (the rationale being that depending on language perhaps
the one-letter command has a meaning already ; anyway if it does the \newcommand
will then raise an error so you will know).
