670 \let\caption@ContinuedFloat\@gobble 671 \let\caption@resetContinuedFloat\@gobble \caption@@ContinuedFloat This hook is for foreign packages which link themself into \ContinuedFloat, for example the subfig package[10]. 672 \providecommand*\caption@@ContinuedFloat[1]{} Internal helpers \caption@begin Our handling of \caption will always be surrounded by \caption@begin (or \caption@beginex) and \caption@end. \caption@begin{〈type〉} performs these tasks: • Call \caption@resetContinuedFloat (see above) and start a new group • Execute the options set with \captionsetup[〈type〉] • Define \fnum@〈type〉 if the caption label format is set to non-default • Override the position= setting, if necessary (for example if set to auto or used inside a supertabular) 673 \newcommand*\caption@begin[1]{% 674 \caption@resetContinuedFloat{#1}% 675 \begingroup 676 \caption@setfloattype{#1}% 677 \ifx\caption@lfmt\caption@lfmt@default\else 678 \@namedef{fnum@#1}{% 679 \caption@lfmt{\caption@floatname{#1}}{\@nameuse{the#1}}}% 680 \fi 681 \caption@fixposition 682 \global\let\caption@fixedposition\caption@position} \caption@beginex \caption@beginex{〈type〉}{〈list entry〉}{〈heading〉} performs the same tasks as \caption@begin and additionally: Redefine \addcontentsline if no list-of entry is requested, that means either the argument 〈list entry〉 is empty or listof= was set to false. 683 \newcommand\caption@beginex[3]{% 684 \caption@begin{#1}% 685 \caption@iflof% 686 {\def\caption@tempa{#2}}% 687 {\let\caption@tempa\@empty}% 688 \ifx\caption@tempa\@empty 689 \long\def\addcontentsline##1##2##3{}% There is no \@gobblethree... 690 \fi 691 \caption@ifempty{#3}{\let\caption@ifempty\@secondoftwo}% 692 } 50
\caption@end \caption@end closes the group. 693 \newcommand*\caption@end{% 694 \endgroup 695 \let\caption@position\caption@fixedposition} \caption@setfloattype \caption@setfloattype{〈type〉} sets up the right float type within \@caption, \LT@makecaption etc. Usually this is equivalent to \caption@settype but I made it an own macro so I can extend it later on, for example if the float or sidecap package is loaded. 696 \let\caption@setfloattype\caption@settype \caption@letfloattype \caption@letfloattype{〈type〉}{〈extra code〉} redefines \caption@setfloattype so it does not only \caption@settype{〈type〉} but two additional tasks: Executing extra code given as second argument and execute options with \caption@settype{#1} afterwards. You can find an example of its usage in the longtable support, where this macro is called so \captionsetup[longtable]{. . . } can be used to setup options for longtables which have a higher priority than the options which have been setup with \captionsetup[table]{. . . } or \setlength\LTcapwidth{. . . }. 697 \newcommand*\caption@letfloattype[2]{% 698 \def\caption@setfloattype##1{% 699 \caption@settype{##1}#2\caption@settype{#1}}} \caption@floatname \caption@floatname{〈type〉} Usually all float names (which partly build the caption label) follow the same naming convention. But some packages (for example the float package) do not, so we use this wrapper macro which can be changed later on. 700 \newcommand*\caption@floatname[1]{\@nameuse{#1name}} 701 \newcommand*\caption@setfloatname[1]{\@namedef{#1name}} Caption support Some packages (like the hyperref package for example) redefines \caption and \@caption, too, but without chaining to their previous definitions. So we have to use \AtBeginDocument here, so we can make sure our definition don’t get lost. 702 \AtBeginDocument{% We only patch \caption and \@caption if the captcont package (which brings it’s own definition of \caption*) is not used. It does not make much sense using the actual version of the caption package with the captcont package, but this was different in the old (v1.x) days so we take care to be backward compatible. 703 \@ifundefined{cc@caption}{% 704 \@ifundefined{caption@old}{% \caption Here comes our definition of \caption and \caption*. (We set \caption@startrue globally so it works with the sidecap package, too.) 51
