listingsnotespage-breaking
I use inline lstlisting-blocks with caption.
I have several listings that are running over more than one page or starting at the end of a page.
Now I want to place a hint for the readers, that the listing hasn't ended and goes further on the next page. This hint should be something like "further listing on next/the next but one page".
I have searched in the section 4 of the listings package manual and haven't found such parameter yet. Is there a possibility to show such a hint?
LaTeX's \label-\ref system by default works along the following lines:
\label{<lab>}, LaTeX stores the last updated counter that used \refstepcounter and the associated page number in the .aux file. \label actually uses \@currentlabel, which is set by \refstepcounter. This step only occurs at page shipout to ensure that the correct page number is associated with the label;\ref retrieves the counter written during \label (\@currentlabel) while \pageref retrieves the accompanying page number.listings has a counter for each lstlisting (the counter lstlisting), but also a counter for each line of a specific listing (the counter lst@lineno).
If you wish to reference the counter for the listing, place your \label immediately after the listing \caption. If you wish to reference the counter for a line within the listing, place your \label on the appropriate line.
If you want all minted environments to be centered and you don't need the Verbatim environment (provided by fancyvrb) for other purposes, then
\documentclass{article}
\usepackage{lipsum} % just for the example
\usepackage{minted}
\RecustomVerbatimEnvironment{Verbatim}{BVerbatim}{}
\renewcommand{\figurename}{Listing}
\begin{document}
\lipsum[2]
\begin{figure}[htp]
\centering
\begin{minted}{prolog}
somePredicate(A, B) :-
arbitraryPredicate(A),
anotherPredicate(B).
\end{minted}
\caption{My Prolog Predicate}
\label{lst:firstListing}
\end{figure}
\end{document}
If, instead, you want to choose between centered and full width minted environments, define a cminted environment; the definition is a bit convoluted: we save a copy of \minted and modify it to issue the \RecustomVerbatimEnvironment command locally.
\documentclass{article}
\usepackage{lipsum}
\usepackage{minted}
\usepackage{xpatch,letltxmacro}
\LetLtxMacro{\cminted}{\minted}
\let\endcminted\endminted
\xpretocmd{\cminted}{\RecustomVerbatimEnvironment{Verbatim}{BVerbatim}{}}{}{}
\renewcommand{\figurename}{Listing}
\begin{document}
\lipsum[2]
\begin{figure}[htp]
\centering
\begin{cminted}{prolog}
somePredicate(A, B) :-
arbitraryPredicate(A),
anotherPredicate(B).
\end{cminted}
\caption{My Prolog Predicate}
\label{lst:firstListing}
\end{figure}
\end{document}

You could use the help of
mdframedand expecially its optionssingleextra,firstextra,secondextraandmiddleextra. The different options allow you to have different styles for a frame that's on a single page and a frame that is broken over two or more pages.When
mdframedis used withframemethod=tikzyou have access to the corners of a frame. The node on the lower left corner is called(O)and the one on the upper right(P). The lower right one can thus be accessed by(O -| P)and the upper left one by(P -| O).This can be used in combination with
\lstnewenvironmentto get a customized listings environment that does what one wants.Below I define a
mdframedstyle that adds some continuing information if a frame is split and a newlistingsenvironment that uses this frame style. Here is how it looks:And here is the code:
