% \author{Yegor Bugayenko \\ \texttt{yegor256@gmail.com}}
% \date{\filedate, \fileversion}
%
% \maketitle
%
% \section{Introduction}
%
% This package renders slide decks in the 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 that this package be employed in conjunction with
% \href{https://github.com/yegor256/clicks}{clicks}:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \usepackage[static]{clicks}
% \begin{document}
% Slide decks may be composed in \LaTeX:
% \plick{\pptBanner{Making Slides Is Easy}}
% \plick{Simply employ this package\ldots}
% \plush{together with the 'clicks' package.}
% The result resembles what PowerPoint
% produces, yet with the precision of \LaTeX.
% Use in concert with ``clicks'' is recommended.
% \end{document}
% \end{docshot}

% \section{Layout}

% \DescribeMacro{\pptToc}
% \DescribeMacro{\pptChapter}
% First, the narrative is divided 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| renders the table of contents in an interactive ``clickable'' format.
% Through the use of \href{https://github.com/yegor256/crumbs}{crumbs}, a navigation
% appears at the upper left corner.

% \DescribeMacro{\pptSection}
% Sections are then placed within 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 employed in tandem render
% an elegant two-level navigation menu at the upper left corner.

% \DescribeMacro{\pptLeft}
% \DescribeMacro{\pptRight}
% The title of the presentation and the author's name may be placed at the foot
% 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
% Should neither the |\pptLeft| nor the |\pptRight| command be used, nothing
% is printed at the foot.

% \section{Commands}

% \DescribeMacro{\pptPic}
% An image may be added to a slide (the first argument denotes the width
% of the image relative to |\textwidth|, while the second supplies its path):
% \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}
% A code fragment may be added to a slide (the use of \href{https://github.com/yegor256/ffcode}{ffcode} is recommended):
% \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}
% |\plick| or |\plush| should not be used here, as they do not function with code snippets.
% The |\pptHeader| command prints a header similar to that produced by the |\pptSection| command,
% yet without commencing a new section.

% \DescribeMacro{\pptQuote}
% \DescribeMacro{\pptBanner}
% A quotation may be placed beside an image by means of the |\pptQuote| command:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \pptBanner{A Cherished Quote}
% \pptQuote{socrates.jpg}{The only true wisdom
% lies in knowing that one knows nothing}{Socrates}
% \end{document}
% \end{docshot}

% \DescribeMacro{\pptThought}
% For a noteworthy thought to be placed at the centre of the slide, |\pptThought| is employed:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \pptThought{Socrates said that the only true
% wisdom lies in knowing that one knows nothing.
% Was he a wise man?...}
% \end{document}
% \end{docshot}

% \DescribeMacro{pptMiddle}
% Content may be positioned vertically at the centre of the page by means of the |pptMiddle| environment:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \begin{pptMiddle}
% ``One's time is limited; it ought not be
% wasted living someone else's life.'' --- Steve Jobs
% \end{pptMiddle}
% \end{document}
% \end{docshot}

% \DescribeMacro{\pptQR}
% On occasion, it is more convenient to present a QR code to the audience in lieu of
% a URL, since the former is more readily consulted---it may simply be scanned:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% The blog post may be consulted at: \\
% \pptQR{https://www.yegor256.com}
% \end{document}
% \end{docshot}
% The code is rendered thus by virtue of the \href{https://ctan.org/pkg/qrcode}{qrcode} package
% employed internally.

% \DescribeMacro{pptWide}
% \DescribeMacro{pptWideOne}
% Slide content occasionally needs to occupy the entire visible horizontal width:
% \begin{docshot}
% \documentclass{article}
% \usepackage[template,scheme=dark]{ppt-slides}
% \begin{document}
% \begin{pptWideOne}
% This paragraph happens to be unusually long,
% and must therefore occupy the entire visible
% horizontal width, although the content
% ordinarily bears a generous left margin.
% \end{pptWideOne}
% \end{document}
% \end{docshot}
% The form |\begin{pptWide}{X}| is likewise admissible,
% where |X| denotes the number of columns to be rendered.

% \section{Package Options}

% \DescribeMacro{template}
% Each slide deck begins with a template:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\documentclass{article}
\usepackage[template=9x6]{ppt-slides}
\begin{document}
...
\end{document}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% Only one template is supplied and is used by default: |9x6|. Should the
% name be omitted, this template is selected. Should the |template| option
% itself be omitted entirely, the default |article| is rendered, which is
% rarely the desired outcome.

% \DescribeMacro{scheme}
% A colour scheme for the slides may be selected by means of the |scheme| option
% of the package:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[template,scheme=light]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% Several schemes are available out of the box: |light|, |dark|,
% |light-mono|, and |dark-mono|. A bespoke scheme may also be devised, taking
% the |ppt-light.tex| file as a model:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[template,scheme=/usr/local/my-colors.tex]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{directory}
% The location of the templates and schemes may be altered 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, when the slide deck is rendered in non-static mode (the |static| option of the ``clicks'' package being absent),
% a minute tracker appears at the upper right corner of each slide. This may be disabled
% by means of the |nominutes| option of the package:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[nominutes]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{nocrumbs}
% By default, the upper left corner of each slide bears so-called crumbs. These may be removed
% by means of the |nocrumbs| package option:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[nocrumbs]{ppt-slides}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \StopEventually{}

% \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.}
% \changes{0.5.0}{2025/04/17}{The \texttt{nocrumbs} package option was introduced.}

% First, we parse the package options:
%    \begin{macrocode}
\RequirePackage{pgfopts}
\makeatletter
\pgfkeys{
  /ppt-slides/.is family,
  /ppt-slides,
  template/.estore in = \ppt@template,
  template/.default = 9x6,
  scheme/.estore in = \ppt@scheme,
  directory/.estore in = \ppt@directory,
  directory/.default = ,
  nominutes/.estore in = \ppt@nominutes,
  nocrumbs/.estore in = \ppt@nocrumbs,
  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
    the 'template' option is not specified}
\fi\makeatother
%    \end{macrocode}

% Then, we include the scheme:
%    \begin{macrocode}
\makeatletter\ifdefined\ppt@scheme
  \RequirePackage{xcolor}
  \input{\ppt@directory ppt-schemes/ppt-\ppt@scheme.tex}
\else
  \message{^^Jppt: No color scheme is loaded, because
    the 'scheme' option is not specified}
\fi\makeatother
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/ifthen}{ifthen}
% in order to enable |if/then/else| commands:
%    \begin{macrocode}
\RequirePackage{ifthen}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/href-ul}{href-ul}
% in order to enable underlined hyperlinks:
%    \begin{macrocode}
\RequirePackage{href-ul}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/pagecolor}{pagecolor}
% in order to make it possible to change the background color of a page:
%    \begin{macrocode}
\RequirePackage{pagecolor}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/varwidth}{varwidth}
% in order to change the width of the page, inside |pptWide|:
%    \begin{macrocode}
\RequirePackage{varwidth}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/csquotes}{csquotes}
% in order to use double quotes:
%    \begin{macrocode}
\RequirePackage{csquotes}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/qrcode}{qrcode}
% in order to render QR codes:
%    \begin{macrocode}
\RequirePackage{qrcode}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/tikz}{tikz}
% in order to position elements on the page, especially in the Table of Contents:
%    \begin{macrocode}
\RequirePackage{tikz}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/tikzpagenodes}{tikzpagenodes}
% in order to pin a block in |\pptPin|:
%    \begin{macrocode}
\RequirePackage{tikzpagenodes}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/enumitem}{enumitem}
% in order to render inline lists in crumbs:
%    \begin{macrocode}
\PassOptionsToPackage{inline}{enumitem}
\RequirePackage{enumitem}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/crumbs}{crumbs}
% in order to show top-page menus:
%    \begin{macrocode}
\RequirePackage{crumbs}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/calc}{calc}
% in order to calculate positions of elements more precisely:
% \changes{0.3.1}{2024/01/13}{The \texttt{calc} package added.}
%    \begin{macrocode}
\RequirePackage{calc}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/tabularx}{tabularx}
% in order to render |\pptQuote|:
%    \begin{macrocode}
\RequirePackage{tabularx}
%    \end{macrocode}

% Then, we include \href{https://ctan.org/pkg/seqsplit}{seqsplit}
% in order to split long links:
%    \begin{macrocode}
\RequirePackage{seqsplit}
%    \end{macrocode}

% \begin{macro}{\pptMiddle}
% \changes{0.2.1}{2022/12/04}{The \texttt{\char`\\pptMiddle} command turned into \texttt{pptMiddle} environment.}
% Then, we define the |pptMiddle| environment:
%    \begin{macrocode}
\newenvironment{pptMiddle}
  {\vspace*{\fill}}
  {\vspace*{\fill}}
%    \end{macrocode}
% \end{macro}

% \begin{macro}{\pptBanner}
% Then, we define the |\pptBanner| command:
%    \begin{macrocode}
\newcommand\pptBanner[2][green]{%
  \par%
  {\setlength{\fboxsep}{6pt}%
    \colorbox{#1}{\color{\thepagecolor}\large #2}}%
  \par%
}
%    \end{macrocode}
% \end{macro}

% \changes{0.8.0}{2026/06/11}{A \texttt{biblatex}-compatible bibliography heading defined.}
% Then, when \href{https://ctan.org/pkg/biblatex}{biblatex} is loaded, we declare
% a bibliography heading that uses |\pptBanner| instead of |\section*|. The
% |crumbs| package redefines |\section| in a way that does not understand its
% starred form, so |biblatex|'s default heading (which issues |\section*{\refname}|)
% would otherwise render as a bogus numbered section. This also makes the references
% slide visually consistent with other |\pptBanner| headings:
%    \begin{macrocode}
\AtBeginDocument{%
  \ifdefined\printbibliography%
    \defbibheading{bibliography}[\refname]{\pptBanner{#1}}%
  \fi%
}
%    \end{macrocode}

% Then, we define the |\pptChapter| and |\pptChapterLabel| commands:
%    \begin{macrocode}
\newcommand\pptChapterLabel{Chapter}

  \end{pptMiddle}%
}
%    \end{macrocode}
% \end{macro}

% \begin{macro}{\pptSection}
% Then, we define the |\pptSection| command:
%    \begin{macrocode}
\newcommand\pptSection[2][]{%
  \subcrumbection[#1]{#2}%
  \pptHeader{#2}%
}
%    \end{macrocode}
% \end{macro}

% \begin{macro}{\pptHeader}
% Then, we define the |\pptHeader| command:

%    \end{macrocode}
% \end{macro}

% \begin{macro}{\pptTitle}
% Then, we define the |\pptTitle| command, which prints the |title| and |subtitle| on the
