%% OPTION HANDLING

% We first handle options then load packages, but we need \definecolor from
% xcolor/color.

% FIXME: we should \RequirePackage{xcolor} always now
% The xcolor package draws better fcolorboxes around verbatim code
\IfFileExists{xcolor.sty}{
    \RequirePackage{xcolor}

%% MISCELLANEOUS CONTEXT
%
% flag to be set in a framed environment
% (defined here as currently needed by three sphinxlatex....sty files and
% even if not needed if such files are replaced, the definition does no harm)
\newif\ifspx@inframed
%
% \spx@ifcaptionpackage (defined at begin document)
%     is needed currently in macros from:
%     sphinxlatexliterals.sty (sphinxVerbatim)
%     sphinxlatextables.sty   (for some macros used in the table templates)
%
% \sphinxcaption is mark-up injected by the tabular and tabulary templates
%     it is defined in sphinxlatextables.sty
%
% store the original \caption macro for usage with figures inside longtable
% and tabulary cells. Make sure we get the final \caption in presence of
% caption package, whether the latter was loaded before or after sphinx.
\AtBeginDocument{%
    \let\spx@originalcaption\caption
    \@ifpackageloaded{caption}
      {\let\spx@ifcaptionpackage\@firstoftwo
       \caption@AtBeginDocument*{\let\spx@originalcaption\caption}%
% in presence of caption package, drop our own \sphinxcaption whose aim was to
% ensure same width of caption to all kinds of tables (tabular(y), longtable),
% because caption package has its own width (or margin) option
       \def\sphinxcaption{\caption}%
      }%
      {\let\spx@ifcaptionpackage\@secondoftwo}%
}

%% PASS OPTIONS
%
% pass options to hyperref; it must not have been loaded already
\input{sphinxoptionshyperref.sty}
% pass options to geometry; it must not have been loaded already
\input{sphinxoptionsgeometry.sty}


%% COLOR (general)
%
% FIXME: these two should be deprecated
%
% FIXME: \normalcolor should be used and \py@NormalColor never defined
\def\py@NormalColor{\color{black}}
% FIXME: \color{TitleColor} should be used directly and \py@TitleColor
% should never get defined.
\def\py@TitleColor{\color{TitleColor}}


%% PACKAGES
%
% as will be indicated below, secondary style files load some more packages
%
% For \text macro (sphinx.util.texescape)
% also for usage of \firstchoice@true(false) in sphinxlatexgraphics.sty
\RequirePackage{amstext}
% It was passed "warn" option from latex template in case it is already loaded
% via some other package before \usepackage{sphinx} in preamble
\RequirePackage{textcomp}
% For the H specifier. Do not \restylefloat{figure}, it breaks Sphinx code
% for allowing figures in tables.
\RequirePackage{float}
% For floating figures in the text. Better to load after float.
\RequirePackage{wrapfig}
% Provides \captionof, used once by latex writer (\captionof{figure})
\RequirePackage{capt-of}
% Support hlist directive
\RequirePackage{multicol}
