% Identify the package and force \LaTeXe:
% \begin{macrocode}
\ProvidesPackage{pdfpc-movie}%
[2018/07/21 v1.0 pdfpc compatible hyperlinking of movies]
\NeedsTeXFormat{LaTeX2e}
% \end{macrocode}
%
% Require additional packages needed by \sty{pdfpc-movie}:
% \begin{macrocode}
\RequirePackage{etoolbox}
\AtEndPreamble{\RequirePackage{hyperref}}
\RequirePackage{pgfkeys}
% \end{macrocode}
%
%
% \subsubsection*{Variables and options}
% Define some internal boolean variables required to assemble the URL parameters:
% \begin{macrocode}
\newif\if@pdfpcmovie@autostart
\newif\if@pdfpcmovie@loop
\newif\if@pdfpcmovie@noprogress
% \end{macrocode}
%
% Define a counter for storing the number of non-processed options:
% \begin{macrocode}
\newcount\pdfpcmovie@remopts
% \end{macrocode}
%
% Define a box and some dimensions to override the poster material's size:
% \begin{macrocode}
\newbox\pdfpcmovie@posterbox
\newdimen\pdfpcmovie@posterwd
\newdimen\pdfpcmovie@posterht
\newdimen\pdfpcmovie@posterdp
% \end{macrocode}
%
% Define the keys available as optional arguments of the "\pdfpcmovie" command.
% Each key requiring additional URL parameters advances "\pdfpcmovie@remopts" by "1":
% \begin{macrocode}
\pgfkeys{%
/pdfpc-movie/width/.cd, .value required,
.code={\pdfpcmovie@posterwd=#1\relax},

% \subsubsection*{The \texttt{\textbackslash pdfpcmovie} macro}
% \begin{macro}{\pdfpcmovie}
% First, "\def" is used to ensure that there is a "\pdfpcmovie" command to (re-)define:
% \begin{macrocode}
\def\pdfpcmovie{}
\renewcommand{\pdfpcmovie}[3][]{%
% \end{macrocode}
%
% Leave vertical mode to ensure correct placement of the movie box
% if "\pdfpcmovie" is used at the beginning of a paragraph:
% \begin{macrocode}
\leavevmode%
% \end{macrocode}
%
% Check whether the requested movie file is present. Emit a warning if it's not:
% \begin{macrocode}
\IfFileExists{\@currdir #3}{}{\PackageWarning{pdfpc-movie}{%
The movie file "#3" could not be found in the current
directory, where it must reside for viewing.}%
}%
% \end{macrocode}
%
%
% Create a box with the poster content and determine its size:
% \begin{macrocode}
\setbox\pdfpcmovie@posterbox=\hbox{#2}%
% \end{macrocode}
%
% Reset all variables to their default values. \\
% After that, the optional argument containing all options gets processed:
% \begin{macrocode}
\@pdfpcmovie@autostartfalse%
\@pdfpcmovie@loopfalse%
\@pdfpcmovie@noprogressfalse%
\let\pdfpcmovie@start\@empty%
\let\pdfpcmovie@stop\@empty%
\pdfpcmovie@posterwd=\wd\pdfpcmovie@posterbox%
\pdfpcmovie@posterht=\ht\pdfpcmovie@posterbox%
\pdfpcmovie@posterdp=\dp\pdfpcmovie@posterbox%
%
\pdfpcmovie@remopts=0%
\pgfkeys{/pdfpc-movie/.cd, #1}%
% \end{macrocode}
%
% All hyperlink arguments appended to the file name are stored in the "\pdfpcmovie@params" variable.
% For every specified option, the respective hyperlink code is appended. \\
% If there are non-processed arguments remaining, an "&" separator is appended:
% \begin{macrocode}
\ifnum\pdfpcmovie@remopts>0\def\pdfpcmovie@params{?}%
\else\def\pdfpcmovie@params{}%
