% \maketitle
%
% \section{Introduction}
%
% This package helps you render slide decks in PowerPoint\texttrademark{} style:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \begin{pptMiddle}
% \pptTitle{Hello, world!}{How are you?}
% \end{pptMiddle}
% \end{document}
% \end{docshot}

% It is recommended to use this package together with
% \href{https://github.com/yegor256/clicks}{clicks}:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \usepackage[static]{clicks}
% \begin{document}
% We help you make slide decks in \LaTeX:
% \plick{\pptBanner{Making Slides Is Easy}}
% \plick{Just use this package...}
% \plush{together with 'clicks' package.}
% They will look similar to what PowerPoint can
% make, but with the precision of \LaTeX. We
% recommend using us together with ``clicks.''
% \end{document}
% \end{docshot}

% \section{Layout}

% \DescribeMacro{\pptToc}
% \DescribeMacro{\pptChapter}
% First, split your story into chapters:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\documentclass{article}
\usepackage{clicks}
\usepackage[template,scheme=light]{ppt-slides}
\begin{document}
\pptToc
\plush{\pptChapter{About Me}}
...
\plush{\pptChapter[Idea]{My Idea Is Novel}}
...
\plush{\pptChapter[FAQ]{Discussion \& Questions}}
...
\end{document}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% |\pptToc| will render the table of contents in an interactive ``clickable'' format.
% Thanks to the use of \href{https://github.com/yegor256/crumbs}{crumbs}, there will
% be a navigation at the top left corner.

% \DescribeMacro{\pptSection}
% Then, put sections inside chapters:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\begin{document}
\pptToc
\plush{\pptChapter{About Me}}
\plush{\pptSection[Student]{I'm a Student}}
...
\plush{\pptSection[Athlete]{Also, I'm an Athlete}}
...
\plush{\pptChapter[Idea]{My Idea Is Novel}}
\plush{\pptSection{Novelty}}
\plush{\pptSection{Impact}}
\end{document}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% The |\pptChapter| and |\pptSection| commands used together will render
% nice two-level nagivation menu at the top left corner.

% \DescribeMacro{\pptLeft}
% \DescribeMacro{\pptRight}
% You can place the title of the presentation and your name at the bottom
% of each slide, on the left and on the right respectively:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\documentclass{article}
\usepackage{clicks}
\usepackage[template,scheme=light]{ppt-slides}
\pptLeft{How Did I Spend Last Summer}
\pptRight{Yegor Bugayenko}
\begin{document}
...
\end{document}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% If you don't use the |\pptLeft| or |\pptRight| commands, nothing will
% be printed at the bottom.

% \section{Commands}

% \DescribeMacro{\pptPic}
% You can add an image to the slide (the first argument is the width
% of the image in relation to |\textwidth|,
% while the second one is the path of it):
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \pptPic{0.2}{socrates.jpg} \\
% This is Socrates, a Greek philosopher.
% \end{document}
% \end{docshot}

% \DescribeMacro{\pptHeader}
% You can add a piece of code to the slide (we recommend using \href{https://github.com/yegor256/ffcode}{ffcode}):
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \usepackage{ffcode}
% \begin{document}
% \pptHeader{This is How You Print to Console:}
% \begin{ffcode}
% void main(char** args) {
%   printf("Hello, world!");
% }
% \end{ffcode}
% \end{document}
% \end{docshot}
% Don't use |\plick| or |\plush|, they won't work with code snippets.
% The |\pptHeader| command prints a header similar to what the |\pptSection| command prints, but
% doesn't start a new section.

% \DescribeMacro{\pptQuote}
% \DescribeMacro{\pptBanner}
% You can put a quote next to the image, by using the |\pptQuote| command:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \pptBanner{My Favorite Quote}
% \pptQuote{socrates.jpg}{The only true wisdom
% is in knowing you know nothing}{Socrates}
% \end{document}
% \end{docshot}

% \DescribeMacro{\pptThought}
% For an interesting thought in the middle of the slide, use |\pptThought|:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \pptThought{Socrates said that the only true
% wisdom is in knowing you know nothing. Was he
% a wise man?...}
% \end{document}
% \end{docshot}

% \DescribeMacro{pptMiddle}
% You can put your content vertically in the middle of the page, using the |pptMiddle| environment:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \begin{pptMiddle}
% ``Your time is limited, so don't waste it
% living someone else's life.'' --- Steve Jobs
% \end{pptMiddle}
% \end{document}
% \end{docshot}

% \DescribeMacro{\pptQR}
% Sometimes it's convenient to show a QR code to your audience instead of
% a URL, since it's easier to use --- they can scan it:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% Check my blog post by this link: \\
% \pptQR{https://www.yegor256.com}
% \end{document}
% \end{docshot}
% The code will look like this, thanks to \href{https://ctan.org/pkg/qrcode}{qrcode} package that
% we use behind the scene.

% \DescribeMacro{pptWide}
% \DescribeMacro{pptWideOne}
% Sometimes you need your slide content to take all visible horizontal space:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \begin{pptWideOne}
% This paragraph is too long for some reasons,
% that's why must take all visible horizontal
% space, while normally the content has a wide
% margin on the left side of the page.
% \end{pptWideOne}
% \end{document}
% \end{docshot}
% You can also use |\begin{pptWide}{X}|,
% where |X| is the number of columns to render.

% \section{Package Options}

% \DescribeMacro{template}
% You start with a template for your slide deck:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\documentclass{article}
\usepackage[template=9x6]{ppt-slides}
\begin{document}
...
\end{document}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% There is only one template, which is used by default: |9x6|. If you don't
% specify the name, it will be used. If you don't use the |template| option at all,
% the default |article| will be rendered, which is not what you want.

% \DescribeMacro{scheme}
% You can choose a color scheme for your slides, using the |scheme| option
% of the package:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[template,scheme=light]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% There are a few out-of-the-box schemes available: |light|, |dark|,
% |light-mono|, and |dark-mono|. You can design your own, using
% |ppt-light.tex| file as an example:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[template,scheme=/usr/local/my-colors.tex]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{directory}
% You can change the location of the templates and schemes by means of the |directory| package option:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[directory=/tmp,template=foo]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{nominutes}
% By default, if you render your slide deck in non-static mode (the |static| option for the ``clicks'' package),
% there will be minutes tracking in the right top corner of each slide. You can turn this off
% by using the |nominutes| option of the package:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[nominutes]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \section{Implementation}
% \changes{0.0.1}{2022/09/11}{First draft.}
% \changes{0.1.4}{2022/09/15}{The \texttt{nominutes} package option added.}
% \changes{0.1.5}{2022/09/19}{The default directory fixed.}
% \changes{0.2.0}{2022/12/03}{We migrated to the \texttt{ltxdoc} format and \texttt{.dtx} file.}

% First, we parse the package options:
%    \begin{macrocode}
\RequirePackage{pgfopts}
\makeatletter
\pgfkeys{
  /ppt-slides/.is family,
  /ppt-slides,
  template/.estore in = \ppt@template,

  directory/.default = ,
  nominutes/.estore in = \ppt@nominutes,
  directory
}
\ProcessPgfPackageOptions{/ppt-slides}
\makeatother
%    \end{macrocode}

% Then, we include the template:
%    \begin{macrocode}
\makeatletter\ifdefined\ppt@template
  \input{\ppt@directory ppt-templates/ppt-\ppt@template.tex}
\else
  \message{^^Jppt: No template is loaded, because
