The~\lstinline!v!~stands for \textquote{variable}, and it is the prefix I recommend using for all standard variables. So for all letters in the alphabet, uppercase and lowercase, as well as the Greek ones, there will be a command: \lstinline!\va!, \lstinline!\vA!, \lstinline!\vb!, \lstinline!\vB!,~etc. -% It is not always necessary to use them; for instance, in the above example, both \lstinline!\vX! and \lstinline!\vU! could have been replaced by simply~\lstinline!X!,~\lstinline!U! without changing anything. This is because we did not apply any arguments to these symbols. However, for the sake of consistency, I prefer to switch completely to using commands instead of writing the symbols directly. -% How \emph{you} use the system is completely up to you. -% -% In \semantex, all entries are being built up from the inside and out. -% The basic syntax layout for most \semantex commands is -% \begin{lstlisting} -%\⟨object⟩[⟨options⟩]{⟨argument⟩} -% \end{lstlisting} -% Let us try focusing on the first example from above: -% \begin{LTXexample} -%$\vf[inverseimage]{\sheafF}[spar,stalk=\vp]$ -% \end{LTXexample} -% You always start with a central piece: a \emph{⟨symbol⟩}. -% In the case of~\lstinline!\vf!, the symbol is~\( f \). After the symbol follows the options we apply to it, written in brackets~\lstinline![...]!. In this case, we the option~\lstinline!inverseimage!. This tells \semantex that we want the inverse image functor~\( \vf[inverseimage] \), so it adds a superscript~\lstinline!-1! to the symbol. After this, we apply the function~\lstinline!\vf[inverseimage]! to something, namely the sheaf~{$\sheafF$}. This is done by enclosing them in braces~\lstinline!{...}!.\footnote{You should be aware that this argument in braces~\texttt{\{...\}} is \emph{optional}. You can simply write~\texttt{$\backslash$vf[inverseimage]} if you want, and it will produce~\smash{\( \vf[inverseimage] \)}.} -% -% -% Next, we want to take the stalk of this sheaf at the point~\( \vp \). If we simply wrote~\lstinline!\vf[inverseimage]{\sheafF}[stalk=\vp]!, we would get~\smash{\( \vf[inverseimage]{\sheafF}[stalk=\vp] \)}, which looks confusing. So we want to enclose~\smash{\( \vf[inverseimage]{\sheafF} \)} in parentheses before taking the stalk. This is done with the key~\lstinline!spar! (an abbreviation for \textquote{symbol parentheses}). -% This key takes whatever has been typed so far, symbol and indices, and adds parentheses around it (of course, type and size is adjustable). -% This~\lstinline!spar! is a key you fill find yourself using a lot. -%\endgroup - \chapter{Getting started} To get started using \semantex, load down the package @@ -2220,7 +2151,7 @@ As you see, we use the \lstinline!d!~key to tell the command what superscript it \chapter{Bugs} -Lots of things can be improved in the system, including the order in which things are being expanded internally.
