% \begin{abstract}
% This package is meant to typeset drama plays using \LaTeX{}. It provides
% commands to introduce characters' lines, to render stage direction, to divide
% a play into acts and scenes, to automatically build the dramatis person\ae{},
% etc.

%
% \section{Introduction}
% This document introduces the \textsf{thalie} package, used to typeset drama
% plays.
%
% \subsection{Other classes and packages}
% This package is far from being the only one that can be used to render drama
% plays. If you do not like my work, you can use one of the following ones (and
% I guess there exists others):
% |drama| \cite{drama},
% |dramatist| \cite{dramatist},
% |play| \cite{play},
% |screenplay| \cite{screenplay},
% |sides| \cite{sides}.
%
% I began to write this package in 2010, and now, at the end of 2012, I must
% admit that I wonder why I started this\ldots There are already several such
% packages in
% \textsc{ctan}\footnote{\url{http://www.ctan.org/topic/drama-script}}, and the
% |dramatist| package seems really nice (I borrowed some ideas and copied some
% code from it). There are actually a few improvements in my package compared
% to |dramatist|: in my package, plays, acts and scenes appear in the table of
% contents; it is possible to include several plays in a single document; there
% are more options when building the dramatis person\ae{}; headers and footers
% are taken into account, etc. But these improvements are small; it might have
% been smarter to contribute to |dramatist| instead of starting my own package.
% The good part is that I have a package that fits my needs, and I learned how
% to write a \LaTeX{} package.
%
% Oh, yes! I know why I started this: I am a geek\ldots
%
% \subsection{License}
% This work may be distributed and/or modified under the
% conditions of the \LaTeX Project Public License, either version 1.3
% of this license or (at your option) any later version.
%
% Further information can be found in the |.dtx| file used to build this
% document.
%
% In short (but this paragraph has no legal value), you can use this package
% freely to render your drama plays, and modify it almost freely. Nevertheless,
% if you like my work, you can invite me to the performance of the play you
% typeset using my package\footnote{You will not take a big risk, since there
% is little chance I travel half the world to see a play. But if by chance I
% can attend it, it would make me really happy.}.
%
% \subsection{Acknowledgements}
% I borrowed ideas and lines of code from the \LaTeX{} packages
% |drama|\cite{drama} and |dramatist|\cite{dramatist}.
%
% I used the following guides to package my package: \emph{How to Package Your
% \LaTeX{} Package} \cite{dtxtut}, and \emph{\LaTeXe{} for class and package
% writers} \cite{clsguide}.
%
% \subsection{Examples}
%
% Most of the examples are taken from Edmond Rostand's \emph{Cyrano de Bergerac}
% \cite{cyrano} or from William Shakespeare's \emph{A Midsummer Night's Dream}
% \cite{midsummer}. The snippets of \emph{Cyrano de Bergerac} are from the
% original (French) version of this play, roughly translated by myself (which
% means that they must be of poor quality).
%
% \subsection{Overview}
% Installation instruction are given in section \ref{sec:install}.
% Documentation about how to use this package is given in section
% \ref{sec:usage}. In particular, section \ref{sec:sectioning} explains how to
% use acts and scenes, sections \ref{sec:dramatis} and \ref{sec:characters} explains how to define
% characters, and use these definitions to introduce characters' lines, and
% section \ref{sec:directions} describes commands used to render stage
% directions. At last, specific instruction about how to use this package with
% a language other than English (or a non-latin alphabet) are given in section
% \ref{sec:i18n}. Examples are given in section \ref{sec:examples}.
%
% Implementation is given in section \ref{sec:implementation}.
%
% \section{Download and Install}
% \label{sec:install}
%
%
% \subsection{\textsc{Gnu}/Linux Distribution}
%
% If applicable, the easiest way to get |thalie| working is by installing it by your distribution package. With Debian (and Ubuntu, and surely other distributions that inherit from Debian), simply run: 
%
% \begin{quote}
% |sudo apt-get install texlive-humanities|
% \end{quote}
%
% \subsection{\LaTeX{} distribution}
%
% This package is included both in \TeX{}Live and MiK\TeX{}. It can be installed by their respective package managers.
%
% \subsection{Manual installation}
%
% \begin{itemize}
% \item Download the lastest archive :
% \begin{description}
% \item[Stable version] \url{http://mirrors.ctan.org/install/macros/latex/contrib/thalie.tds.zip}
% \item[Development version] \url{https://framagit.org/spalax/thalie/repository/archive.zip?ref=main}
% \end{description}
% \item Unzip the archive.
% \item If you got the archive from CTAN (stable version), move file \texttt{tex/latex/thalie/thalie.sty} in a \LaTeX{} path.
% \item If you got the development version, |cd| to the main archive directory, and run |latex thalie.ins| to build |thalie.sty|. Move this file into a \LaTeX{} path.
% \end{itemize}
%
% \section{Usage}
% \label{sec:usage}
%
% \subsection{Localization}
% \changes{v0.09a}{2017/04/22}{Add section \emph{Localization}.}
%
% By default, commands \lstinline|\act|, \lstinline|\scene|, etc. use English words, but they are
% translated to the current language used by |babel| or
% |polyglossia|\footnote{Given that someone provided the translation. See
% \ref{sec:languages} for the list of available languages.}. More information
% is given in section \ref{sec:l10n}.
%
% \subsection{Package options}
% \label{sec:options}
%
% Package options are summed up in table \ref{table:packageoptions}.
%
% Note that any package option can be redefined anywhere in the document. This
% makes it possible to have several plays collected in a single document, while
% applying different styles or options to each play. See section
% \ref{sec:redefine} for more detail.

%
% \subsubsection{Space following character commands and stage directions}
% \label{option:xspace}
% \changes{v0.07}{2015/12/28}{New package option \texttt{xspace}.}
% As commands introducing characters' lines and displaying characters' names
% may be frequently used, it might be tempting to omit the following \lstinline|{}| For
% instance, one might prefer to write:
% \iffalse
%<*example>
% \fi
% \begin{lstlisting}
\cyrano Indeed, \cyranoname is my name!
\end{lstlisting}
% \iffalse
%</example>
% \fi
% instead of:
% \iffalse
%<*example>
% \fi
% \begin{lstlisting}
\cyrano{} Indeed, \cyranoname{} is my name!
\end{lstlisting}
% \iffalse
%</example>
% \fi
%
% If package option |xspace| is set (e.g. |xspace=true|), space is automatically
% added after those commands if necessary\footnote{This is done with
% the |$\backslash$xspace| command (from the |xspace| package), hence the name.};
% otherwise, it is not. The same rule applies after a |\did| command.
%
% For historical reasons, the option |xspace| default is |true|, but this might
% change in some later non-backward compatible version.
%
% \subsubsection{Style}
% The way characters' lines are displayed, as well as play, act and scene
% titles, can be set when loading the options.
% To set character style, use option |characterstyle=|\meta{style}. Available
% styles, and indication to use a custom one, are described in section
% \ref{sec:lines}.
%
% Several play, act and scene title styles are defined. Choose it using options
% |playstyle|=\meta{style}, |actstyle|=\meta{style} and
% |scenestyle|=\meta{style}. Description of available styles, and how to define
% your own one, are described in section \ref{sec:sectionstyles}.
%
% \subsubsection{Sectioning levels}
% If you use a table of contents, or if you also use ``usual'' sectioning
% commands (\lstinline|\chapter|, \lstinline|\section| and so on), the relative importance of
% plays, acts and scenes is important. You can set this using options
% |playlevel=|\meta{level}, |actlevel=|\meta{level} and
% |scenelevel=|\meta{level}. The argument is the name of the corresponding
% sectioning level, i.e. one of |part|, |chapter|, |section|, |subsection|,
% |subsubsection|, |paragraph| and |subparagraph|.
%
% Setting the interlude level is slightly different. While setting it using
% |interludelevel=|\meta{level}, instead of choosing one of \LaTeX{} vanilla
% sectioning levels as the level, you may choose |play|, |act| or |scene|. It
% defines if an interlude is at the same level as a play, an act or a scene.
%
% \subsubsection{Redefining options}
% \label{sec:redefine}
% \DescribeMacro{\setthalieoptions}
%
% Packages options can be reset in the document body using command
% \lstinline|\setthalieoptions|\marg{package options}. Its only argument has the same
% syntax as the package options.
%
% For instance, if you are writing a collections of plays, some in prose, some in verses, you might want to write something like the following.
%
% \iffalse
%<*example>
% \fi
% \begin{lstlisting}
\documentclass{book}
...
\usepackage{thalie}
...
\begin{document}
...
\play{First play}
\setthalieoptions{characterstyle=imprimerie-verse}
...
\play{Second play}
\setthalieoptions{characterstyle=impriemie-prose}
...
\end{document}
\end{lstlisting}
% \iffalse
%</example>
% \fi
%
% \subsection{Sectioning}
% \label{sec:sectioning}
% Here begin the parts explicitly relating to drama.
% \subsubsection{Levels}
% \DescribeMacro{\play}
% \DescribeMacro{\play*}
% \DescribeMacro{\act}
% \DescribeMacro{\act*}
% \DescribeMacro{\scene}
% \DescribeMacro{\scene*}
% To introduce a new play, act or scene, use commands \lstinline|\play|, \lstinline|\act| and
% \lstinline|\scene|. Their behaviour is as close as the ``usual'' sectioning commands
% (\lstinline|\chapter|, \lstinline|\section| and so on) as possible, i.e.:
% \begin{itemize}
% \item Their signature is \lstinline|\play|\oarg{short title}\marg{longtitle} (the
% optional short title is the one used in the table of content, and in headers
% and footers).
% \item A starred version (\lstinline|\play*|, \lstinline|\act*| and \lstinline|\scene*|) is provided, which
% inserts a play (or act, or scene) which is not numbered, and does not insert
% any line in the table of content.
% \item Headers and footers are changed (more information in section \ref{sec:header}).
% \end{itemize}
%
% Both commands \lstinline|\act| and \lstinline|\scene| (and their starred versions) are designed to
% deal with empty titles. Indeed, it is common not to give any name to acts and
% scenes.
%
% By default, a play is as deep (regarding to the table of contents) as a
% chapter, an act as a section, and a scene as a subsection. But this can be
% set using package options |playlevel|, |actlevel| and |scenelevel| (see
% packages options, page \pageref{sec:options}). That way, you can use in your
% document plays, acts and scenes as well as chapters, sections and so on. It
% can be useful if you want a foreword, and appendix, etc.
%
% It is not compulsory to use all three commands \lstinline|\play|, \lstinline|\act| and \lstinline|\scene|.
% The rule of thumb is: if only one element exists, skip the corresponding
% command: if your document has a single play, you should ignore \lstinline|\play|; if
% your document has several single act plays, set
% |playlevel=section,scenelevel=subsection| and ignore \lstinline|\act|; etc.
%
% \DescribeMacro{\interlude}
% \DescribeMacro{\interlude*}
% You may want to use interludes, which are acts or scenes which are not
% numbered, but which should appear in the table of content. Command
% \lstinline|\interlude|\oarg{short title}\marg{long title} has this purpose.
%
% You may choose the sectioning level an interlude is equivalent to in the
% package options. If your interludes are acts, use |interludelevel=act|; if
% they are scenes, use |interludelevel=scene|.
%
% \DescribeMacro{\curtain}
% At last, to mark the end of an act or of the play, you can use command
% \lstinline|\curtain|, which prints the word \lstinline|\GetTranslation{Curtain}| in the middle of its
% own line.
%
% \subsubsection{Title styles}
% \label{sec:sectionstyles}
% Several styles are available to render play, act and scene titles. Choose
% them using package options |playstyle|, |actstyle| and |scenestyle|. Default
% is |playstyle=box|, |actstyle=bigcenter|, |scenestyle=center|.
%
% \paragraph{Custom titles}
% Unfortunately, as play, act and scene titles are not considered (by \LaTeX{})
% as usual sections, package
% |titlesec|\footnote{\url{http://www.ctan.org/pkg/titlesec}} cannot be used to
% use alternative section titles. Here is the way to set your own one.
%
% \begin{figure}[p]
% \centering
% \iffalse
%<*example>
% \fi
% \begin{lstlisting}
\newcommand\customact[2]{
  \begin{center}
    \textsc{\GetTranslation{Act} #1}

    #2
  \end{center}
}
\WithSuffix\newcommand\customact*[1]{
  \begin{center}
    #1
  \end{center}
}
\end{lstlisting}
% \iffalse
%</example>
% \fi
% \caption{Example of custom act definition}
% \label{fig:custom}
% \end{figure}
%
% \DescribeMacro{\customplay}
% \DescribeMacro{\customact}
% \DescribeMacro{\customscene}
% When loading the package, use |custom| as the style of the title you want to
% customize (e.g. |actstyle=custom|). Then, commands
% \lstinline|\customact|\marg{counter}\marg{title} and \lstinline|\customact*|\marg{title} will be
% called by this package to render titles. You \emph{must} define them. Figure
% \ref{fig:custom} gives the example of the definition of the |center| style.
%
% The first argument of \lstinline|\customact| is the label of the act being printed
% (that is, \lstinline|\theact| for an act, \lstinline|\theplay| for a play, etc.), its second
% argument is its title. Command \lstinline|\customact*| only has one argument, which is
% the act title.
% 
% \subsubsection{Labels and counters}
%
% \DescribeMacro{\theplay}
% \DescribeMacro{\theact}
% \DescribeMacro{\thescene}
% Using the same tools as \lstinline|\chapter|, \lstinline|\section| and so on, it is possible to
% define the way counters of plays, acts and scenes are displayed. You can do
% this by redefining \lstinline|\theplay|, \lstinline|\theact| and \lstinline|\thescene|. For example, to
% have acts numbered using letters, use \lstinline|\renewcommand{\theact}{\Alph{act}}|.
%
% \subsubsection{Headers and footers}
% \label{sec:header}
%
% \DescribeMacro{\playmark}
% \DescribeMacro{\actmark}
% \DescribeMacro{\scenemark}
% Once again, similar tools as those used by \lstinline|\section| are provided to deal
% with headers and footers. When introducing, a new play, act or % scene,
% respectively, commands \lstinline|\playmark|\marg{label}, \lstinline|\actmark|\marg{label} and
% \lstinline|\scenemark|\marg{label} are called, so that titles can be used in headers
% and footers. If the default behaviour does not suit you (which should be the
% case if you did not choose the default option for |playlevel|, |actlevel| or
% |scenelevel|), you can redefine them.
%
% Examples are given in section \ref{sec:examples:headers}.
%
% \subsection{Dramatis person\ae}
% \label{sec:dramatis}
% This part explains how to build and display the dramatis person\ae{}.
%
% Definition of characters is done in document body.
% As it is possible to have several plays in a single documents (for a
% collection of plays or sketches), it is possible to define several
% dramatis person\ae{}. A new one disables the character commands
% defined by the previous one.
%
% \DescribeEnv{dramatis}
% Definition of characters is done inside the |dramatis| environment. If the
% |hidden| option is given, the dramatis person\ae{} is not printed (its
% only purpose is then to define the character commands).
%
% \begin{quote}
%   \lstinline|\begin{dramatis}|\oarg{hidden}
% \end{quote}
%
% Then, several commands are available to define characters, and organize
% character definitions.
%
% \DescribeMacro{\characterspace}
% Command \lstinline|\characterspace| put some vertical space into the dramatis
% person\ae{}.
%
% \subsubsection{Character definition}
% \paragraph{Basic definition}
% \label{paragraph:basiccharacter}
% 
% \begin{figure}[p]

% \begin{quote}%
% \lstinline|\character|\oarg{\emph{cmd=}command,\emph{drama=}dramatis,\emph{desc=}description}\marg{name}%
% \end{quote}
% The mandatory argument is the name of the character, as it will appear in each of this character's line. It is later possible to redefine it using command \lstinline|\setcharactername| (see part \ref{setcharactername}). Optional arguments are:
% \begin{description}

% \subsection{Characters}
% \label{sec:characters}
% This part explains how to define characters, and introduce character's lines.
%
% It has been explained that definition of a character in the dramatis
% person\ae{} (previous subsection) also creates commands used to introduce
% lines of characters. For instance, defining a character using
% \lstinline|\character[cmd=cyrano]{Cyrano}| means than Cyrano's lines can now be
% introduced using the following code.
% \iffalse
%<*example>
% \fi
\begin{lstlisting}
\cyrano
No! It's a bit short, young man\ldots
\end{lstlisting}
% \iffalse
%</example>
% \fi
% This would display the name \emph{Cyrano} using the current character style, then
% his line.
%
% \subsubsection{Custom characters}
%
% \paragraph{Disposable character}
% \DescribeMacro{\disposablecharacter}
% One can need to define characters that are used only once (or a few times).
% Command \lstinline|\disposablecharacter| is here to help.
% \begin{quote}\lstinline|\disposablecharacter|\oarg{directions}\marg{name}\end{quote}
% This command, used in the body, introduces a line for character |name|, with optional stage
% directions. It is rendered the same way regular characters are rendered, but
% nothing is added to the dramatis person\ae{}. It is used in figure
% \ref{fig:setcharactername_example}.
%
% This command is also useful to introduce lines of characters in non standard
% ways, for instance if several characters speak at once. See examples in
% section \ref{sec:examples:characterslines}.
%
% \subsubsection{Changing character's name}
% \label{setcharactername}
% \DescribeMacro{\setcharactername}
%
% \begin{figure}[p]
% On the first scenes of Cyrano de Bergerac, the main character (Cyrano) is

% \caption{Example of changing the name of a character}

%
% It is possible to change the name that appears to introduce character's lines
% within the text. This can be used, for example, when a character is first

% \emph{Cyrano}. An example is given in figure
% \ref{fig:setcharactername_example}.
% \begin{quote}\lstinline|\setcharactername|\marg{command}\marg{name}\end{quote}
%
% This command takes two mandatory arguments. The first one, |command|, is the
% command used to introduce this character's line. The second one is the name
% to display for this character.
%
% \subsubsection{Lines}
% \label{sec:lines}
% To introduce characters' lines, use the commands defined in the character
% definition (see the \lstinline|\character| command, or the example in figure
% \ref{fig:character_example}).
%
% \paragraph{Choose style}
% \changes{v0.06}{2014/06/25}{New character styles \texttt{imprimerie-verse}, \texttt{imprimerie-prose} and \texttt{arden}.}
% Several styles are available, to typeset character's name and lines in
% different ways. Change the style by loading package using option
% |characterstyle=|\marg{style} (available styles are |bold|, |center|,
% |margin|, |simple|, |imprimerie-verse|, |imprimerie-prose|). A few notes:
% \begin{itemize}
% \item Default style is |simple|.
% \item |imprimerie-verse| and |imprimerie-prose| styles are French
% \emph{de facto} standards for typesetting drama plays, respectively in verse
% and in prose, as defined by the \emph{Imprimerie nationale}
% \cite{imprimerienationale}.
% \item |arden| tries to mimick typesetting of the Arden Shakespeare series.
% \item |bold| needs a sans serif font to be defined (it should be done by
% default with latin alphabets, but must be done by hand with languages using
% non latin characters (greek, hindi, etc.)).
% \end{itemize}
%
% \paragraph{Customize style}
% \DescribeMacro{\speakswithoutdirection}
% \DescribeMacro{\speakswithdirection}
% If available styles does not fit your need, you can also define your own one.
% To do so, you can redefine the following commands.
% \begin{quote}
% \lstinline|\speakswithoutdirection|\marg{name}\\
% \lstinline|\speakswithdirection|\marg{name}\marg{direction}
% \end{quote}
% The first one (\lstinline|\speakswithoutdirection|) is invoked to display a character's name
% to introduce its line. It takes one argument, which is the character's line.
% The second one (\lstinline|\speakswithdirection|) is also invoked to display a character's
% name to introduce its line, but it takes a second argument, which is stage
% directions to be printed together with character's name.
%
% See also section \ref{sec:directions} to see other ways to print stage
% directions.
%
% \subsection{Stage directions}
% \label{sec:directions}
% Let us begin with a warning: since we could not figure out a nice command
% name made from ``stage directions'', we used the French word
% \emph{(didascalie)} to build up command names.
%
% \DescribeMacro{\did}
% \DescribeEnv{dida}
% We define two ways to render stage directions: a short one, that is printed
% inline, and a long one, printed in its own paragraph\footnote{For people writing math:
% They act a bit like \lstinline|$1+1=2$| and \texttt{\bbackslash[1+1=2\bbackslash]} for formulas.}.
% The first way is the command \lstinline|\did|\marg{directions}. The second way is the
% environment |dida|.
%
% Note that option \lstinline|xspace| may be used to automatically add a space,
% if necessary, after a \lstinline|\did| command (see section \ref{option:xspace}, page \pageref{option:xspace}).
%
% \DescribeMacro{\onstage}
% Some stage directions are displayed centered under the scene or act
% definition (I often see it in classical drama, where the list of characters
% appearing in each scene is displayed that way). Command
% \lstinline|\onstage|\marg{directions} can be used to display such information.
%
% \DescribeMacro{\pause}
% As we often need to mark pauses in theater, we created the command \lstinline|\pause|,
% which is a shortcut for \lstinline|\did{\GetTranslation{Pause}}|.
%
% \subsection{Splitting verses}
%
% When writing verses, it is sometimes useful to split a verse between two
% characters: the first character starts it in its line, and the second one
% finishes it in a second line. Visually, the start of the second line is
% vertically aligned to the end of the first line.

% Warning: this is still experimental. I present several recipes to achieve this, but they all have their pros and cons.
%
% \DescribeMacro{\pauseverse}
% \DescribeMacro{\resumeverse}
% The recipes presented below all implement macros \lstinline|\pauseverse| and \lstinline|\resumeverse|.
% Command \lstinline|\pauseverse|  is used at the end of the verse to be continued, while command \lstinline|\resumeverse| is used at the beginning of the continuing verse. See figure \ref{fig:splitverse} (page \pageref{fig:splitverse}) for an example.
%
% When writing a play in verse, one can use a lot of those commands, which can
% be tedious because of their long names. So, defining ``shortcuts'' of those
% commands can be handy, as in the following example.

%
% This is not done by default, because short command names are a scarce ressource
% in \LaTeX, so, defining these commands by default might conflict with other
% packages, while most of |thalie| users will not use them.
%
% \subsubsection{Which recipe should I use?}
%
% As I have already stated, there are several ways to achieve this, but none of them is perfect.
%
% \begin{itemize}
% \item Do try the first recipe (section \ref{split-latex}). If it works, stick to it. Otherwise…
% \item If you do not mind loading the \texttt{TikZ} package, use it (section \ref{split-tikz}). As far as I know, from a user point of view, it is the easiest recipe to use, with the less bugs. Otherwise…
% \item You can try building you own commands (section \ref{split-hanging}). Otherwise…
% \item The last recipe (section \ref{split-phantom}) always works. It is far less user-friendly, but it does the job.
% \end{itemize}
%
% \subsubsection{Recipe 1 : Pure \LaTeX}
% \label{split-latex}

% \danger
% Warning: I do not understand the code behind this feature. I copied-pasted code by David Carlisle\footnote{Originally written as an answer to a StackExchange question: see \url{https://tex.stackexchange.com/a/107727}.} without understanding it. There are \sout{probably} bugs\footnote{One on them lead to the next recipe.}, but I won't be able to solve them.
%
% The implemented macros \lstinline|\pauseverse| and \lstinline|\resumeverse| are written in pure \LaTeX (without any external package). For backward compatibility reasons, this will remain the default implementation for some time…
%
% \DescribeMacro{\adjustverse}
% If the character names are displayed on the same line as the verse, the lines
% are not aligned the way one would expect them to. To correct this, command
% \lstinline|\adjustverse|\marg{length} can be used to add an extra (possibly negative)
% space when calling \lstinline|\resumeverse|, to get a correct alignment.
% See figure \ref{fig:splitverse-adjusted}, page \pageref{fig:splitverse-adjusted}, for an
% example of those three commands.
%
% The young inexperienced fool\footnote{Me…} who originally wrote those commands had not noticed that \lstinline|\adjustverse| is needed because \lstinline|\resumeverse| does not take into account the length of the character names, in styles where it appears on the same line as the verse. This (probably) won't be fixed, because some people might be using this, and fixing this might break their document.
% 
% If you encounter the same issue, you might prefer one of the other recipes.
%
% \subsubsection{Recipe 2 : With package \texttt{hanging}}
% \label{split-hanging}
%
% \danger
% Warning: This is a do-it-yourself recipe.
%
% The bug announced at the end of the previous recipe, has been spotted and partially corrected by egreg on StackExchange\footnote{\url{https://tex.stackexchange.com/a/545326}}. He proposes the following code to fix this.
%
% \iffalse
%<*example>
% \fi
% \begin{lstlisting}
\usepackage{hanging}

\newlength{\brokenverse}
\renewcommand*{\speakswithoutdirection}[1]{%
  \settowidth{\brokenverse}{\textsc{#1}.}%
  \hangpara{2\parindent}{1}\noindent\textsc{#1}.%
}
\makeatletter
\renewcommand{\resumeverse}{%
  \hspace{\@verseadjust}\hspace{\dimexpr\dimen\@ne-\brokenverse-2em}
}
\makeatother
\end{lstlisting}
% \iffalse
%</example>
% \fi
%
% This code ignores the choosen style (it actually redesigns it), and it only works with lines without character directions. If needed, you should also define a \lstinline|\speakswithdirection| command to implement the same feature.
%
% \subsubsection{Recipe 3 : With package \texttt{TikZ}}
% \label{split-tikz}
%
% % As far as I know, this recipe is the best one, from a user point of view. But it loads the \texttt{TikZ} package, which is a huge package to implement such a tiny feature\footnote{In French, we would say : \enquote{\foreignlanguage{french}{Un marteau-pilon pour écraser une mouche}} (a far too heavy solution for a tiny problem).}.

% At last, if nothing else workd, this feature can also be implemented using the \lstinline|\phantom| command (see figure \ref{fig:splitverse-phantom} for an example, page \pageref{fig:splitverse-phantom}).
% It is far less user-friendly, but it is also less error prone. Choose wisely…

%
% \subsection{Localization}
% \label{sec:l10n}
%
% \changes{v0.09a}{2017/04/22}{Use package |translations| for localization.}
%
% Language cannot be defined directly in this package. Instead, the language
% currently used by |babel| or |polyglossia| is used to translate the following
% words (with or without capital letter, singular or plural): \emph{play},
% \emph{act}, \emph{scene}, \emph{interlude}, \emph{pause}, \emph{curtain}.
%
% If the option for your language does not exist\footnote{You can also send me
% the translation for your language, to improve this package.}, or if you want
% to change the default words used here, you can set your own translation
% using command \lstinline|\DeclareTranslation| (see the |translations| package for more
% information). For instance use
% \lstinline|\DeclareTranslation{Spanish}{Curtain}{Tel\`on}| for Spanish\footnote{I may
% be wrong: I cannot speak Spanish.}.
%
% See section \ref{sec:languages} for the list of supported languages.
%
% \subsubsection{Common translations}
% \DescribeMacro{\playname}
% \DescribeMacro{\actname}
% \DescribeMacro{\scenename}
% \DescribeMacro{\interludename}
% \DescribeMacro{\pausename}
% \DescribeMacro{\curtainname}
%
% Commands defined here are shorter versions of strings commonly translated.
%
% For instance, \lstinline|\playname| is a shortcut for \lstinline|\GetTranslation{Play}|,
% \lstinline|\actname| is a shortcut for \lstinline|\GetTranslation{Act}|, and so on.
%
% \subsection{Non-latin alphabets}
%
% This package should work with languages using non-latin alphabets (greek,
% hindi, etc.). However, here are a few remarks.
%
% \begin{itemize}
% \item The |bold| character style (see section \ref{sec:lines}) can only be used if a sans serif font has been defined. For instance, for hindi, you might write in the preamble: \lstinline|\newfontfamily\hindifontsf{Noto Sans Devanagari}|.
% \end{itemize}
%
% \subsection{Language specific comments}
% \label{sec:languages}
%
% \changes{v0.10a}{2019/02/24}{New translation: German (thanks Ekkart Kleinod).}
% \changes{v0.11a}{2022/06/15}{New translation: Italian (thanks Giuseppe Palma).}
%
% The following languages are available:
%
% \begin{itemize}
% \item English,
% \item French,
% \item German,
% \item Italian.
% \end{itemize}
%
% \subsubsection{English}
%
% \begin{itemize}
% \item The |arden| character style tries to mimick the typestting of the Arden Shakespeare series.
% \end{itemize}
%
% \subsubsection{French}
%
% \begin{itemize}
% \item The |imprimerie-verse| and |imprimerie-prose| character styles implements the French \emph{de facto} standards for typesetting drama plays, respectively in verse and in prose, as defined by the \emph{Imprimerie nationale} \cite{imprimerienationale}.
% \item The same book (\cite{imprimerienationale}) states that act numbers should be typeset in capital roman numerals (which is done by default with |thalie|), and that scene numbers should be typeset in small capital roman numerals, which is \emph{not} the default, but can be achieved by adding the following line in the preamble: \lstinline|\renewcommand{\thescene}{\textsc{\roman{scene}}}|.
% \end{itemize}
%
% \subsubsection{Other languages}
%
% I do not know anything related to other languages. If you have interesting advice for those languages that you would like to share (preferably with a reference to a reliable source), I would be happy to add them to this list!

% \subsection{Characters' lines}
% \label{sec:examples:characterslines}
%
% \subsubsection{Introduce lines of several characters at the same time.}
%
% Since \lstinline|\disposablecharacter| can display arbitrary text using the style of
% character names, it can be used to render a custom text when two characters
% are speaking together.
%
% \iffalse
