\def\SR@special@num{0}

% we start by messing a little with listings

\newtoggle{capactive}
% this is a direct copy of listings caption key. We just add a toggle
% such we can know when it is being used
\lst@Key{caption}\relax{%
  \lstKV@OptArg[{#1}]{#1}%
    {\def\lst@caption{##2}\def\lst@@caption{##1}}%
    \toggletrue{capactive}%
    \def\SR@special@num{1}%
     \let\lst@title\@empty}

% we also need to mess with title, because, if there is not explicit
% caption, we would still like to overwrite the auto title with a
% simple title
\newtoggle{titleactive}
\lst@Key{title}\relax{%
  \def\lst@title{#1}%
  \toggletrue{titleactive}%
  \def\SR@special@num{2}%
  \let\lst@caption\relax}




% replica of the original caption key without the toggle. We will use this
% internally to be able to auto number our constuctions when there is
% no direct caption.
\lst@Key{nocaption}\relax{\lstKV@OptArg[{#1}]{#1}%
    {\def\lst@caption{##2}\def\lst@@caption{##1}}%
     \let\lst@title\@empty}

% This next bit is caption configuration. The code is due to Ulrike Fischer
% we define a text formatting which will eat the caption
\DeclareCaptionTextFormat{gobble}{}

% now in the numbered constructions we would like to have 'Name
% number' when there is no caption, and 'Name number&lt;sep&gt; text' when
% there is a caption.

% This can be done using \lstset{nocaption=x,#1} inside our
