% \section{Introduction}
%
% The \pkg{poetrytex} package is designed to aid in the formatting and
% typesetting of anthologies of poetry.
%
% \subsection{History}
%
% The package started out as a collection of macros for automating simple tasks
% that I often had to perform while working on a collection of poetry and prose.
% After a time, I decided to turn it into an STY file which would be geared
% more towards the idea of an anthology or a collection of works and less about
% typesetting the verse itself (for which there were already several good
% packages on CTAN). While the file was small this worked well---Learning to
% use the package was easily accomplished by reading the annotated source code
% (generated via a modified version of Jeremy Ashkenas' literate programming
% tool `docco'). However, as the source and scope of the project grew I decided
% to move away from docco and start working on a proper package that would use
% more traditional \TeX-style docs.
%
% \subsection{License / about the source}
%
% This project may be distributed and/or modified under the conditions of the
% \LaTeX\ Project Public License, either version 1.3c of this license or (at
% your opinion) any later version. The latest version of this license is in:
%
% \url{http://www.latex-project.org/lppl.txt}
%
% and version 1.3c or later is part of all distributions of \LaTeX\ version
% 2008/05/04 or later.
%
% Contributions are welcome, and the latest development version of the project
% can always be found at \url{https://github.com/samwhited/poetrytex}.
%
% \subsection{Acknowledgements}
%
% A special thanks is in order for Brittany Taylor. Though she probably has no
% idea what \TeX\ is or that this project even exists it is due mostly to her
% influence that it ever got off the ground.

% \section{Package building and loading}
%
%    \begin{macrocode}
%<*poetrytex>
%    \end{macrocode}
%
% \paragraph{Building}
%
% Before building \pkg{poetrytex} you should verify that the following
% dependencies are installed:
% \changes{1.0}{2012/07/18}{Removed \pkg{fontspec} / \pkg{xelatex} dependency}
% \changes{1.2}{2012/10/03}{Removed \pkg{parskip} dependency}
% \changes{1.2}{2012/10/03}{Removed default \pkg{hyperref} options}
% \changes{1.3}{2012/10/03}{Load \pkg{hyperref} at end of package}
%    \begin{macrocode}
\RequirePackage{expl3}
\AtEndOfPackage{\RequirePackage{hyperref}}
%    \end{macrocode}
% Once you have all the required packages, building \pkg{poetrytex} from source
% can be accomplished in multiple ways. If the Makefile is present running
% \code{make help} will tell you everything you need to know. To manually
% extract the files and generate the documentation simply run \code{pdflatex}
% or \XeLaTeX\ against \fname{poetrytex.dtx}:
%
% \begin{Verbatim}
%   pdflatex poetrytex.dtx
% \end{Verbatim}
%
% You can also use the \code{-{}-shell-escape} option to generate documentation
% which includes the current git commit short-hash in the version number:
%
% \begin{Verbatim}
%   pdflatex --shell-escape poetrytex.dtx
% \end{Verbatim}
%
% It should be noted that this option is extremely unsafe and you should only
% use it if you understand the risks.
%
% \paragraph{Loading}
%
% Using \pkg{poetrytex} in your project works exactly as you'd expect:
%
% \begin{Verbatim}
%   \usepackage{poetrytex}
% \end{Verbatim}
%
% \hypertarget{POETRYTEX:OPTIONS}{}
% \changes{1.2}{2012/10/03}{Added various package options}
% \begin{macro}{verse}
% \begin{macro}{numbertop}
% \begin{macro}{resetnumongroup}
% \begin{macro}{numberpoems}
% \begin{macro}{clearpageafterpoem}
% The package can also be loaded with any of the following options:
%    \begin{macrocode}
\DeclareOption{verse}{\usepackage{verse}}
\DeclareOption{numbertop}{\numbertop}
\DeclareOption{resetnumongroup}{\resetnumongroup}
\DeclareOption{numberpoems}{\numberpoems}
\DeclareOption{clearpageafterpoem}{\clearpageafterpoem}
\DeclareOption{clearpageafterpoems}{\clearpageafterpoem}
\DeclareOption*{%
  \PassOptionsToPackage{\CurrentOption}{hyperref}%
}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
% \end{macro}
% \end{macro}
%
% For instance:
%
% \begin{Verbatim}
%   \usepackage[numberpoems,clearpageafterpoem]{poetrytex}
% \end{Verbatim}
%
%
% \part{Document setup and structure}
%
% The \pkg{poetrytex} package is fairly simple as far as \TeX\ packages go, so
% it's worth taking a look at how it works internally.
%
% \section{Environment setup and defaults}
%
% First we setup our environment, define some useful properties, and choose some
% default values for those properties.
%
% \subsection{Title page}
%
% We'll start with the title page:
%
% \begin{macro}{\pttitle}
% \begin{macro}{\ptsubtitle}
% \begin{macro}{\ptauthor}
% \begin{macro}{\ptdate}
% These properties will affect the appearance of \code{\textbackslash%
% maketitle}:
%    \begin{macrocode}
\newcommand*{\pttitle}{Title}
\newcommand*{\ptsubtitle}{Subtitle}
\newcommand*{\ptauthor}{Author}
\newcommand*{\ptdate}{\today}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
% \end{macro}
%
% Since we define them as commands, you can change the appearance of your
% title page by redefining them in your preamble like so:
%
% \begin{Verbatim}
%   \renewcommand*{\pttitle}{My Title}
%   \renewcommand*{\ptauthor}{The Author}
% \end{Verbatim}
%
% We then use these properties to set the document title, author, and date:
%    \begin{macrocode}
\title{%
  \pttitle%
  \ifx\ptsubtitle\@ptundefined\relax\else\\\ptsubtitle\fi%
}
\author{\ptauthor}
\date{\ptdate}
%    \end{macrocode}
% Since \code{\textbackslash maketitle} clears the internal title, author, and
% date we use the \code{\textbackslash pt} equivalents so that we can refer to
% them again later, or redefine them throughout the document---in anthologies
% with works by multiple authors, for instance.
%
% \subsection{Poem config}
%
% \begin{macro}{\@ptpoemlabeltext}
% Each time you create a poem in your document we automatically assign it a
% special label that can be used to link to it later. This label is prefixed
% with \code{\textbackslash @ptpoemlabeltext} to prevent it from conflicting
% with user defined labels, or labels defined in other packages.
%    \begin{macrocode}
\newcommand*{\@ptpoemlabeltext}{poetrytexpoem:}
%    \end{macrocode}
% \end{macro}
%
% Chances are you'll never need to touch this.
%
% \begin{macro}{poemnum}
% \begin{macro}{absolutepoemnum}
% The \code{poemnum} and \code{absolutepoemnum} counters will be incremented
% every time we include a poem in our document and can be used later to number
% the poems. The \code{absolutepoemnum} counter will never be reset by \pkg{%
% poetrytex} while \code{poemnum} may sometimes be reset to 0 (at the beginning
% of a new \code{poemgroup} for instance).
%    \begin{macrocode}
\newcounter{poemnum}
\newcounter{absolutepoemnum}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\ptdefaultenv}
% \changes{1.2}{2012/09/20}{Added an option to change the default environment}
% This contains the name of the default environment in which we should wrap
% poems.
%    \begin{macrocode}
\newcommand*{\ptdefaultenv}{verse}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\ptannotationenv}
% \changes{1.3}{2012/10/30}{Added an option to change the default annotation
% environment}
% This contains the name of the default environment in which we should wrap
% annotations.
%    \begin{macrocode}
\newcommand*{\ptannotationenv}{flushleft}
%    \end{macrocode}
% \end{macro}
%
% \subsection{Dedication}
%
% After your title page you might want to add a dedication page.
%
% \begin{macro}{\ptdedication}
% \begin{macro}{\makededication}
% \changes{1.1}{2012/07/21}{Added optional `environment' argument}
% As with the \code{\textbackslash pttitle} and author commands you can simply
% redefine \code{\textbackslash ptdedication} to change the dedication text.
%
% To create a dedication page, the \code{\textbackslash makededication} command
% can be called. By default, this command aligns everything to the right,
% however, by adding an optional argument you can specify any environment to
% wrap the dedication in.
%    \begin{macrocode}
\newcommand*{\ptdedication}{Renew \textsf{\textbackslash ptdedication}}
\newcommand*{\makededication}[1][flushright]{%
  \thispagestyle{empty}
  \vspace*{\fill}
  \begin{#1}
    \emph{\ptdedication}
  \end{#1}
  \vspace*{\fill}
}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \subsection{Tables and links}
%
% Next we setup the table of contents and list of poems:
%
% \begin{macro}{\toptitle}
% \begin{macro}{\topentrytype}
% The value of \code{\textbackslash toptitle} will be rendered atop the Table of
% Poems, and \code{\textbackslash topentrytype} will set the default entry type
% for poems in the TOP.
%    \begin{macrocode}
\newcommand*{\toptitle}{List of Poems}
\newcommand*{\topentrytype}{subsection}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% We then set the \code{secnumdepth} and \code{tocdepth} counters to disable
% chapter, section, and subsection numbering, and to limit the maximum depth of
% entries in the TOC.
%
%    \begin{macrocode}
\setcounter{secnumdepth}{-1}
\setcounter{tocdepth}{2}
\renewcommand*{\listtablename}{\toptitle}
%    \end{macrocode}
%
% \begin{macro}{\maketoc}
% \begin{macro}{\maketop}
% \begin{macro}{\maketop*}
% Once you've configured the TOC and TOP you probably want to insert them into
% your document somewhere. While you could just use the \LaTeX\ commands \code{%
% \textbackslash tableofcontents} and \code{\textbackslash listoftables}, we
% provide alternatives that add a bit of formatting and clear the page. By
% default the TOP creates a listing in the TOC---Using the star modifier
% prevents this. An example table of poems can be found at the end of this
% document.
%    \begin{macrocode}
\newcommand*{\maketoc}{%
  \tableofcontents
  \pagestyle{plain}
  \clearpage
  \thispagestyle{empty}
}
\newcommand*{\maketop}{\@ifstar{\@ptmaketopStar}{\@ptmaketopNoStar}}
\newcommand*{\@ptmaketopStar}{%
  \listoftables
  \pagestyle{plain}
  \clearpage
}
\newcommand*{\@ptmaketopNoStar}{%
  \cleardoublepage
  \phantomsection
  \addcontentsline{toc}{section}{\toptitle}
  \listoftables
  \pagestyle{plain}
  \clearpage
}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\numbertop}
% Placing this command in your document preamble will cause the table of poems
% to be numbered.
%    \begin{macrocode}
\newcommand*{\numbertop}{\newcommand*{\@ptnumbertop}{}}
%    \end{macrocode}
% \end{macro}
%
% \part{Poems and annotations}
%
% Now that we've got all the boilerplate, configuration, titles, tables, and
% properties out of the way, it's time to move on to the core functionality of
% \pkg{poetrytex}: displaying and organizing poems!
%
% \section{The \code{poem} environment}
%
% \begin{environment}{poem}
% \changes{1.2}{2012/09/20}{Use \code{hypertarget} instead of \code{label}}
% Inserting a poem or other writing into your anthology is accomplished by
% wrapping it in the \code{poem} environment. This environment takes in two
% arguments, the title and subtitle (or author, date, etc.) of the poem.
%    \begin{macrocode}
\newenvironment{poem}[3][\ptdefaultenv]{%
%    \end{macrocode}
%
% By default \code{poem} re-wraps your text in the \code{verse} environment.
% However, this can be changed by passing in an optional argument with the name
% of another environment to wrap it in (eg. \code{center}) or, for all poems, by
% redefining \code{ptdefaultenv}.
%
%    \begin{macrocode}
  \newcommand*{\@ptwrapenvironment}{#1}
%    \end{macrocode}
% For example, a poem wrapped in the \code{center} environment might look like
% this:
%
% \begin{Example}
% \begin{Verbatim}
% \begin{poem}[center]
% {The Sea Bell}{J.R.R. Tolkien}
% I walked by the sea,
% and there came to me,\\
% as a star-beam on the wet sand,\\
% a white shell like a sea-bell;\\
% trembling it lay
% in my wet hand.\\
% In my fingers shaken
% I heard waken\\
% a ding within, by a harbour bar\\
% a buoy swinging, a call ringing\\
% over endless seas,
% faint now and far\ldots
% \end{poem}
% \end{Verbatim}
% \columnbreak
% \begin{poem}[center]
% {The Sea Bell}
% {J.R.R. Tolkien}
% I walked by the sea,
% and there came to me,\\
% as a star-beam on the wet sand,\\
% a white shell like a sea-bell;\\
% trembling it lay in my wet hand.\\
% In my fingers shaken I heard waken\\
% a ding within, by a harbour bar\\
% a buoy swinging, a call ringing\\
% over endless seas,
% faint now and far\ldots
% \end{poem}
% \end{Example}
%
% Now we render the page header, title, and the actual poem:
%    \begin{macrocode}
  \poetryheadings
  \addtocounter{poemnum}{1}
  \addtocounter{absolutepoemnum}{1}
  \begin{center}
    \phantomsection%
    \addcontentsline{lot}{\topentrytype}{%
      \ifx\@ptnumbertop\@ptundefined%
        \relax%
      \else%
        \arabic{poemnum}.\ %
      \fi#2}%
    \hypertarget{\@ptpoemlabeltext\arabic{absolutepoemnum}}{}
    {\poemtitleformat%
      \ifx\@ptnumberpoems\@ptundefined
        \relax
      \else
        \arabic{poemnum}\\%
      \fi#2}\\%
    #3
  \end{center}
  \begin{\@ptwrapenvironment}
  \begingroup\setlength{\parskip}{\stanzaparskip}
}{%
  \endgroup
  \end{\@ptwrapenvironment}
  \ifx\@ptclearpageafterpoem\@ptundefined
    \relax
  \else
    \clearpage
  \fi
}
%    \end{macrocode}
% \end{environment}
%
% \section{Formatting}
%
% The \code{poem} environment provides some reasonable defaults for formatting
% your work but chances are you want a little more control.
%
% \subsection{Headings}
%
% \begin{macro}{\poetryheadings}
% Every time a new \code{poem} or \code{annotation} environment is created we
% automatically call \code{\textbackslash poetryheadings}. By redefining this
% you can change how your headings look, use packages like \pkg{fancyhdr}, or
% remove headers from poem pages altogether.
%    \begin{macrocode}
\newcommand*{\poetryheadings}[0]{%
  \pagestyle{myheadings}
  \markboth{ | \MakeUppercase{\pttitle}\hfill }
           {\hfill\MakeUppercase{\ptgroup}\ | }
}
%    \end{macrocode}
% \end{macro}
%
% \subsection{Numbering}
%
% \begin{macro}{\resetnumongroup}
% \begin{macro}{\numberpoems}
% These commands determine if the \code{poemnum} counter should be reset when
% the poem group changes and if the poems should display their number above the
% title. Generally these should be called from the preamble but they can be
% defined at any point in your document to change how numbering works, or to
% turn on numbering from that point forward.
%    \begin{macrocode}
\newcommand*{\resetnumongroup}{\newcommand*{\@ptresetnumongroup}{}}
\newcommand*{\numberpoems}{\newcommand*{\@ptnumberpoems}{}}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% Using \code{\textbackslash numberpoems} results in:
%
% \begin{Example}
% \begin{Verbatim}
% \numberpoems
%
% \begin{poem}{The Highwayman}
% {Alfred Noyes}
% The wind was a torrent of
% darkness among the gusty trees,\\
% The moon was a ghostly galleon
% tossed upon cloudy seas,\\
% The road was a ribbon of
% moonlight over the purple moor%
% \ldots
% \end{poem}
% \end{Verbatim}
% \columnbreak
% \numberpoems
%
% \begin{poem}{The Highwayman}{Alfred Noyes}
% The wind was a torrent of
% darkness among the gusty trees,\\
% The moon was a ghostly galleon
% tossed upon cloudy seas,\\
% The road was a ribbon of
% moonlight over the purple moor%
% \ldots
% \end{poem}
% \end{Example}
%
% \subsection{Spacing and indentation}
%
% \begin{macro}{\stanzaparskip}
% This length is used to change the \code{parskip} within a poem environment.
%    \begin{macrocode}
\newlength{\stanzaparskip}
\setlength{\stanzaparskip}{0.7em}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\clearpageafterpoem}
% \code{clearpageafterpoem} causes the page to be cleared after every poem
% environment.
%    \begin{macrocode}
\newcommand*{\clearpageafterpoem}{\newcommand*{\@ptclearpageafterpoem}{}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\ptgap}
% \begin{macro}{\ptind}
% \begin{macro}{\ptind*}
% The \code{\textbackslash ptgap} length and \code{\textbackslash ptind}
% command are two of those places where \pkg{poetrytex} strays a bit into the
% realm of poetry typesetting. They overlap with the \pkg{verse} package's
% \code{\textbackslash vgap} and \code{\textbackslash vin} commands and insert
% indentation at at the beginning of a line. This is useful for typesetting
% poems consistently when the \pkg{verse} package is not loaded. Redefine
% \code{\textbackslash ptgap} to change the length that \code{\textbackslash%
% ptind} indents by. The starred version of \code{ptind} uses\code{%
% \textbackslash hspace*}.
%    \begin{macrocode}
\newlength{\ptgap}
\setlength{\ptgap}{2em}
\newcommand*{\ptind}{%
  \@ifstar{%
    \@ptindStar
  }{%
    \@ptindNoStar
  }
}
\newcommand*{\@ptindStar}{\hspace*{\ptgap}}
\newcommand*{\@ptindNoStar}{\hspace{\ptgap}}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% Using it works something like this:
%
% \begin{Example}
% \begin{Verbatim}
% \setlength{\ptgap}{2em}
% \begin{poem}[flushleft]{PoE\TeX}
% {An {\tipaencoding
% /Ig"zA:mp@l/} poem}
% There once was a poem called%
% PoE\TeX\\*
% That's name sounded somewhat%
% {\tipaencoding /p@"TEtEk/}.\\*
% \ptind It was really quite%
% sad,\\*
% \ptind to see pronunciation%
% so bad,\\*
% And to read such a terrible%
% {\tipaencoding /"lIme(@)rEk/}!
% \end{poem}
% \end{Verbatim}
% \columnbreak
% \setlength{\ptgap}{2em}
% \begin{poem}[flushleft]{PoE\TeX}

% \ptind to see pronunciation%
% so bad,\\*
% And to read such a terrible%
% {\tipaencoding /"lIme(@)rEk/}!
% \end{poem}
% \end{Example}
%
% \subsection{Style}
%
% \begin{macro}{\poemtitleformat}
% By redefining \code{\textbackslash poemtitleformat} we can change how the poem
% title is rendered.
%    \begin{macrocode}
\newcommand*{\poemtitleformat}{\normalfont\bfseries\large\centering}
%    \end{macrocode}
% \end{macro}
%
%
% If you want a stylistic marker between two poems, or between sections
% or stanzas within a poem, the following commands are your friend.
%
% \begin{macro}{\ptspacergap}
% \begin{macro}{\ptspacerchar}
% \begin{macro}{\ptspacernum}
% The \code{ptspacergap} length is the indentation of the spacer, and\code{%

% \code{\textbackslash ptspacernum} times.
%    \begin{macrocode}
\newlength{\ptspacergap}

\newcommand*{\ptspacerchar}{\S}
\newcommand*{\ptspacernum}{3}
%    \end{macrocode}

% \end{macro}
%
% \begin{macro}{\ptspacer}
% \changes{1.0}{2012/07/17}{Repeat \code{\textbackslash ptspacernum} times}
% \begin{macro}{\ptspacer*}
% The starred version of the \code{ptspacer} command uses \code{\textbackslash%
% hspace*} for indention.
%    \begin{macrocode}
\newcommand*{\ptspacer}{%

% \subsection{Groups and linking}
%
% When putting together a large collection of poetry and prose you most likely
% need a way to organize your works and find them quickly. While the table of
% poems helps we might also want to link directly to poems, or further subdivide
% the collection into groups of related works (by year written, or subject
% matter for instance).
%
% \begin{macro}{\linktopoem}
% \changes{1.1}{2012/07/24}{Fix spacing and multiple use issues}
% \changes{1.2}{2012/09/20}{Use \code{hyperlink} when linking to a poem}
% We can \emph{\linktopoem[1]{link}} \emph{\linktopoem[2]{to}}%
% \emph{\linktopoem[3]{poems}} easily enough by providing \code{linktopoem} with
% the text for the link and, optionally, the number of the poem to link to. If
% only one argument is given it is used as both the link destination and text.
%    \begin{macrocode}
\newcommand*{\linktopoem}[2][ptnull]{%
  \ifx{#1}{ptnull}
    \hyperlink{\@ptpoemlabeltext#2}{#2}\relax

% \begin{macro}{\ptgroup}
% \begin{macro}{\poemgroup}
% \begin{macro}{\poemgroup*}
% Dividing poems up into groups can be accomplished with the \code{%
% \textbackslash poemgroup} command. The command creates a title-page for the
% group at the current location and adds entries to the TOP and TOC unless the
% starred version of the command is used. The \code{\textbackslash ptgroup}
% command will always contain a reference to the current group in case you need
% to refer to it later.

%
% \begin{environment}{annotation}
% \changes{1.1}{2012/07/20}{Added optional `environment' argument}
% Annotations allow you to insert prose that relates to a specific poem into
% your document. It uses \code{\textbackslash poetryheadings}, clears the page
% twice, and adds itself to the TOC (but not the TOP). The page is also cleared
% again after the annotation.
%
% Like the \code{poetry} environment, an optional first argument can be used to
% specify the environment in which the annotation will be wrapped. The default
% is \code{flushleft} and can be changed by redefining \code{ptannotationenv}.
