This forces the brackets to be properly balanced. This is extremely useful in come packages, such as Seman\TeX, where you can then +do things that would otherwise cause errors, e.g. +\begin{lstlisting}[mathescape=false] +\StrictBracketsOn + $ \vf[upper=\vx[upper=2,lower=3]] $ +\StrictBracketsOff +\end{lstlisting} +Normal brackets can still be accessed by using the standard \TeX\ commands +\lstinline!\lbrack! and \lstinline!\rbrack!. +The replacement algorithm has two important exceptions: +\begin{itemize} + \item \emph{No} replacements apply to the commands~\lstinline!\[...\]!, which can therefore be used as normal. + \item If you absolute \emph{need} ordinary brackets, + you can write \lstinline!<[>! and~\lstinline!<]>! to access them. This works + in all contexts, so e.g. \lstinline!\<[>! and~\lstinline!\<]>! will work + just like \lstinline!\[! and~\lstinline!\]!. +\end{itemize} + +\newpage + +\chapter*{Allowing numbers (and possibly primes) in commands} + +The package provides the commands +\begin{lstlisting} +\NumbersInCommandsOn +\NumbersInCommandsOff +\NumbersAndPrimesInCommandsOn +\NumbersAndPrimesInCommandsOff +\end{lstlisting} +The first pair of commands allows you to define commands containing numbers.
