Selecting a caption style means saving the additional 〈single-line-list-of-KV〉 (this will be
done by \caption@sls), resetting the caption options to the default ones (this will be
done using \caption@setdefault) and executing the 〈list-of-KV〉 options (this will
be done using \caption@esetup).
The starred version will give no error message if the given style is not defined.
206 \newcommand\caption@setstyle{%
207 \@ifstar{\caption@@setstyle\@gobble}{\caption@@setstyle\@firstofone}}
208 \newcommand*\caption@@setstyle[2]{%
209 \@ifundefined{caption@sty@#2}%
210 {#1{\caption@Error{Undefined caption style ‘#2’}}}%
211 {\expandafter\let\expandafter\caption@sls\csname caption@sls@#2\endcsname
212 \caption@setdefault\caption@esetup{\csname caption@sty@#2\endcsname}}}
\caption@setdefault This resets (nearly) all caption options to the default ones. Note that this does not touch
the skips and the positioning!
213 \newcommand\caption@setdefault{\captionsetup{%
214 format=default,labelformat=default,labelsep=default,textformat=default,%
215 justification=default,font=default,labelfont=default,textfont=default,%
216 margin=0pt,indent=0pt,parindent=0pt,hangindent=0pt,%
217 singlelinecheck=1,strut=1}}
Currently there is only one pre-defined style, called ‘default’. It’s a perfect match to the
behaviour of \@makecaption offered by the standard LATEX document classes: If the
caption fits in one single line, it is typeset centered.
