+% \begin{abstract}
+% In the \acl{US}, secondary and undergraduate students
+% are generally expected to adhere to the format prescribed by
+% the \ac{MLA} for typewritten essays, research papers and writings.
+% Sadly, the tool of choice is usually Microsoft Word,
+% even amongst those fluent with \TeX .
+%
+% Though there \emph{are} some templates and tools to aid in
+% writing in the \ac{MLA} format using \LaTeX ,
+% none fully met the expectations of the author.
+% So \foreign{voil\`a}, there now exists an \Dfile{mla.cls} proper:
+% a simple, straightforward class for composing papers
+% almost perfectly adherent to the
+% \ac{MLA} style guide\footfullcite{mlahb}.

+% \label{sec:initial_code}
+%
+% The \Dcls{mla} class uses the \Dcls{article} class as its base.

+% work as expected and won't have to be re-defined.
+% \begin{macrocode}
+\LoadClass[letterpaper,12pt]{article}
+% \end{macrocode}
+%
+% \begin{macro}{\mladate}
+% The \citetitle{mlahb} requires use of the \term{day month year}
+% date format, not \TeX 's standard \term{month day, year}.
+% The macro \cs{mladate} will format \cs{today} accordingly
+% to be used as the default value for \cs{date}
+% (see section~\ref{sec:the_header}).

+% \section{Options}
+% \label{sec:options}
+%
+% Some teachers and professors might still require using
+% the seventh edition of the \citetitle{mlahb},
+% while others will likely use the eighth edition.
+% Which edition to implement can be explicitly specified
+% with the \Dopt{mla7} and \Dopt{mla8} class options.
+% The only difference this makes within the \Dcls{mla} class itself
+% is the citation format used by \Dpkg{biblatex}.
+%
+% \changes{v0.3}{2019/05/06}{Improved options parsing to avoid
+% contradiction and undefined behavior}
+% \changes{v0.5}{2019/05/21}{Changed options parser to use
+% toggle-switch commands in the style of default \LaTeX\ classes}
+% \changes{v0.7}{2019/05/30}{Changed options parser to use
+% \cs{ifMLA@\ldots} toggle format seen in other classes}
+% \begin{macrocode}
+\DeclareOption{mla7}{\MLA@seventrue\MLA@eightfalse\MLA@eightaltfalse}
+\DeclareOption{mla8}{\MLA@sevenfalse\MLA@eighttrue\MLA@eightaltfalse}
+% \end{macrocode}
+%
+% \changes{v0.3}{2019/05/07}{Added \Dopt{mla8alt} option}
+% Some versions of \Dpkg{biblatex-mla} might not recognize
+% the \Dopt{style=mla-new} option for the eighth edition.
+% In this case, one can specify \Dopt{mla8alt}
+% to the \Dcls{mla} class.
+% \begin{macrocode}
+\DeclareOption{mla8alt}{\MLA@sevenfalse\MLA@eightfalse\MLA@eightalttrue}
+% \end{macrocode}
+%
+% The \Dpkg{microtype} package can be optionally included
+% with the \Dopt{microtype} option to offset the pain of using
+% the Times typeface.
+% \begin{macrocode}
+\DeclareOption{microtype}{\MLA@microtypetrue}
+% \end{macrocode}

+% \subsection{Processing}
+% \label{sec:processing}

+% is provided.
+%
+% \begin{macrocode}
+\DeclareOption*{%
+ \ClassWarning{mla}{Unknown option `\CurrentOption'; ignoring}
+}
+% \end{macrocode}
+%
+% By default, the eighth edition of the \citetitle{mlahb} is used.
+% To future-proof your documents for upcoming editions, however,
+% it may be wise to explicitly specify \Dopt{mla8}.

+% \section{Loading packages}
+% \label{sec:loading_packages}
+%
+% The \Dcls{mla} class requires the following packages\footnote{All
+% of the required packages are available for download
+% on the \ac{CTAN} if unavailable on your system:
+% \url{https://www.ctan.org/}.}:
+%
+% \changes{v0.3}{2019/05/07}{Replaced obsolete \Dpkg{times} package
+% with \Dpkg{newtxtext}}
+% \changes{v0.4}{2019/05/11}{Added \Dpkg{microtype} package}
+% \changes{v0.4}{2019/05/12}{Added \Dpkg{enumitem} package}
+% \changes{v0.6}{2019/05/29}{Added \Dpkg{caption} package}
+% \changes{v0.6}{2019/05/29}{Added \Dpkg{graphicx} package}
+% \changes{v0.6}{2019/05/29}{Added \Dpkg{float} package}
+% \changes{v0.7}{2019/06/01}{Changed \Dpkg{microtype} package
+% to only load through \Dopt{microtype} class option}
+% \begin{macrocode}
+\RequirePackage{caption}
+\RequirePackage{enotez}
+\RequirePackage{enumitem}
+\RequirePackage{fancyhdr}
+\RequirePackage{float}
+\RequirePackage{fullpage}
+\RequirePackage{graphicx}
+\RequirePackage{ragged2e}
+\RequirePackage{newtxtext}
+\RequirePackage{titlesec}
+\RequirePackage{xstring}
+% \end{macrocode}
+%
+% The following consists of prerequisites for \Dpkg{biblatex-mla}:
+%
+% \changes{v0.2}{2019/05/02}{Hid hyperlink boxes in \acs{PDF} output}
+% \changes{v0.2}{2019/05/02}{Added support for \acs{PDF} metadata}
+% \begin{macrocode}
+\RequirePackage[american]{babel}
+\RequirePackage{csquotes}
+\RequirePackage{hanging}
+% \end{macrocode}
+%
+% And finally, \Dpkg{biblatex}.
+% The \Dcls{mla} class options dictate what options are passed to
+% \Dpkg{biblatex}, hence the \term{if-then} clauses.
+%
+% \begin{macrocode}
+\ifMLA@seven
+ \RequirePackage[style=mla,noremoteinfo=false,showmedium=true,
+ backend=biber]{biblatex}
+\fi
+\ifMLA@eight
+ \RequirePackage[style=mla-new,noremoteinfo=false,
+ showmedium=false,backend=biber]{biblatex}
+\fi
+\ifMLA@eightalt
+ \RequirePackage[style=mla,noremoteinfo=false,
+ showmedium=false,backend=biber]{biblatex}
+\fi
+% \end{macrocode}
+%
+% The \Dpkg{microtype} package is loaded if the \Dopt{microtype}
+% option is specified.
+%
+% \begin{macrocode}
+\ifMLA@microtype
+ \RequirePackage{microtype}
+\fi
+% \end{macrocode}
+%
+% For some reason, common practice is to load \Dpkg{hyperref} last
+% of all packages.
+%
+% \begin{macrocode}
+\RequirePackage{hyperref}
+\hypersetup{hidelinks,pdfusetitle}
+% \end{macrocode}
+%
+% \section{Document layout}
+% \label{sec:document_layout}
+%
+% \subsection{Font}
+% \label{sec:font}
+%
+% The \Dpkg{newtxtext} package was already loaded in
+% section~\ref{sec:loading_packages},
+% and the font was set to 12pt when loading the \Dcls{article} class
+% in section~\ref{sec:initial_code}.
+% This should be metric-compatible with the infamous Times New Roman,
+% the \foreign{de facto} standard of the
+% \ac{MLA} format\footnote{According to the popular, oft-referenced
+% \ac{OWL}: \citeurl{owlmla}.}.
+%
+% \subsubsection{Microtype}
+% \label{sec:microtype}
+%
+% The \Dpkg{microtype} package (if loaded as in
+% section~\ref{sec:loading_packages})
+% will marginally offset the burden of using Times
+% by correcting its ugly kerning and tracking.
+% The vague \Dopt{activate=false} below simply disables
+% protrusion, maintaining original line and page breaks.
+%
+% \changes{v0.4}{2019/05/12}{Disabled \Dpkg{microtype} protrusion}
+% \begin{macrocode}
+\ifMLA@microtype
+ \microtypesetup{activate=false}
+\fi
+% \end{macrocode}
+%
+% \subsection{Line breaking and spacing}
+% \label{sec:line_breaking}
+%
+% The \citetitle{mlahb} prescribes exact double-spacing,
+% the definition of which varies between typesetters.
+% With these parameters exact, \LaTeX\ produces 23 lines of text
+% whereas the \soCalled{industry standard}
+% Microsoft Word\footnote{Microsoft Word 97 through 2016,
+% and likely following versions as well.} produces 24.
+% To compensate, line spacing is set to \emph{just enough}:
+%
+% \changes{v0.4}{2019/05/08}{Changed \cs{linespacing} to
+% print 24 lines per page}
+% \begin{macrocode}
+\linespread{1.905}
+% \end{macrocode}
+%
+% Though not explicitly denounced in the \citetitle{mlahb},
+% most \ac{MLA}-style papers don't hyphenate or adjust spacing
+% for pretty typesetting.
+%
+% \begin{macrocode}
+\hyphenpenalty=10000
+\pretolerance=10000
+% \end{macrocode}
+%
+% \subsection{Paragraphing}
+% \label{sec:paragraphing}
+%
+% The \citetitle{mlahb} specifies half-inch first-line indentation
+% for every paragraph and no extra spacing in between.
+%
+% \begin{macro}{\MLA@indent}
+% \changes{v0.7}{2019/06/05}{Added macro}
+% In case the indent should be changed, several other macros relying
+% on it might be broken.
+% Using an internal like \cs{MLA@indent} prevents this.
+%
+% \begin{macrocode}
+\newlength{\MLA@indent}
+\setlength{\MLA@indent}{0.5in}
+% \end{macrocode}
+% \end{macro}
+%
+%
+% \changes{v0.6}{2019-05-29}{Explicitly set \cs{partopset} to 0pt}
+% \begin{macrocode}
+\setlength{\parindent}{\MLA@indent}
+\setlength{\RaggedRightParindent}{\MLA@indent}
+\setlength{\parskip}{0em}
+\setlength{\topsep}{0em}
+\setlength{\partopsep}{0em}
+% \end{macrocode}
+%
+% \TeX\ does not indent the first paragraph after headings by default.
+% Thankfully, the fix for this is simple.
+%
+% \changes{v0.7}{2019/05/31}{Copied code from \Dpkg{indentfirst}
+% to reduce dependency count}
+% \begin{macrocode}
+\let\@afterindentfalse\@afterindenttrue
+\@afterindenttrue
+% \end{macrocode}
+%
+% And, for the sake of consistent 24-line papers,
+% orphans and widows are explicitly allowed.
+%
+% \begin{macrocode}
+\widowpenalty=0
+\clubpenalty=0
+\interlinepenalty=0
+% \end{macrocode}
+%
+% For a final heinous crime against typesetting,
+% the \citetitle{mlahb} advises flush-left/ragged-right alignment.
+% (This is acheived with the \Dpkg{ragged2e} package.)
+%
+% \begin{macrocode}
+\RaggedRight
+% \end{macrocode}
+%
+% \begin{environment}{noindent}
+% The \Denv{noindent} environment doesn't work as expected
+% in conjunction with \Dpkg{ragged2e}, hence the re-definition.
+%
+% \begin{macrocode}
+\renewenvironment{noindent}{%
+ \edef\tmpind{\parindent}
+ \setlength{\parindent}{0pt}
+}{%
+ \setlength{\parindent}{\tmpind}
+ \undef{\tmpind}
+}
+% \end{macrocode}
+% \end{environment}
+%
+% \subsection{Page layout}
+% \label{sec:page_layout}
+%
+% With few exceptions, the \ac{US} uses \soCalled{letter-size} paper.
+% The paper size was already set when loading the \Dcls{article} class
+% in section~\ref{sec:initial_code}.
+%
+% Furthermore, the \citetitle{mlahb} dictates uniform one-inch margins
+% on said paper.
+% This was already set by the \Dpkg{fullpage} package as loaded
+% in section~\ref{sec:loading_packages}.
+% The \cs{textheight} and \cs{textwidth} definitions are here
+% just for good measure.
+%
+% \begin{macrocode}
+\setlength{\textheight}{9in}
+\setlength{\textwidth}{6.5in}
+% \end{macrocode}
+%
+% \subsection{Running head}
+% \label{sec:running_head}
+%
+% The running head in \ac{MLA} style is simply the author's surname
+% followed by the current page number, right-aligned.
+% This is managed using the \Dpkg{fancyhdr} and \Dpkg{xstring} packages.
+%
+% \begin{macrocode}
+\fancypagestyle{norule}{%
+ \renewcommand{\headrulewidth}{0pt}
+ \renewcommand{\footrulewidth}{0pt}
+}
+\fancyhf{}
+\pagestyle{headings}
+\pagestyle{norule}
+\fancyhead[RO]{{\StrBehind{\@author}{ }[\last]\last} \thepage}
+% \end{macrocode}
+%
+% The following code is largely a hack to align the header
+% in the middle of the one-inch margin above the body text.
+%
+% \begin{macrocode}
+\setlength{\headheight}{18pt}
+\setlength{\headsep}{12pt}
+\setlength{\voffset}{-34pt}
+% \end{macrocode}
+%
+% \section{Document markup}
+% \label{sec:document_markup}
+%
+% \subsection{The header}
+% \label{sec:the_header}
+%
+% \begin{macro}{\title}
+% \begin{macro}{\author}
+% \begin{macro}{\date}
+% The \cs{title}, \cs{author} and \cs{date} macros work as expected.
+% However, if your surname contains a space, you must contain the
+% surname in braces as such:
+% {\small |\author{Ludwig {van Beethoven}}|}.
+% This keeps the full surname in the running head (see
+% section~\ref{sec:running_head}).
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% The following header commands are unique to the \Dcls{mla} class.
+%
+% \begin{macro}{\professor}
+% The instructor who assigned the paper, i.e.
+% \mentioned{Dr. Marjorie Stewart}.
+%
+% \begin{macrocode}
+\newcommand*{\professor}[1]{\gdef\@professor{#1}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\course}
+% The course for which this paper was assigned, i.e.
+% \mentioned{ENGL 101-02}.
+%
+% \begin{macrocode}
+\newcommand*{\course}[1]{\gdef\@course{#1}}
+% \end{macrocode}
+% \end{macro}
+%
+% To prevent undefined behavior, the internal macros used
+% to store the above information are set empty, except for \cs{date}.
+% (Note the use of \cs{mladate}; see section~\ref{sec:initial_code}.)
+%
+% \begin{macrocode}
+\title{}
+\author{}
+\professor{}
+\course{}
+\date{\mladate}
+% \end{macrocode}
+%
+% \begin{macro}{\makemlaheader}
+% This command finally prints out the standard four-line
+% \ac{MLA} header, as well as the title.
+%
+% \changes{v0.2}{2019/05/02}{Changed date format to
+% \term{day month year}}
+% \changes{v0.4.1}{2019/05/15}{Changed date format back to whatever

+% \begin{macrocode}
+\newcommand{\makemlaheader}{%
+ \begin{noindent}
+ \@author \\
+ \@professor \\
+ \@course \\
+ \@date \\
+ \begin{center}\@title\end{center}
+ \end{noindent}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% For simplicity's sake, \cs{maketitle} is directly aliased
+% to \cs{makemlaheader}.
+%
+% \begin{macrocode}
+\renewcommand{\maketitle}{\makemlaheader}
+% \end{macrocode}
+%
+% Finally, the header will print at the beginning of every document.

+% Section headings are neither defined nor discouraged
+% in the \citetitle{mlahb}, though commonly used in longer papers.
+% Customary section headings are rather straightforward,
+% consisting of the section number in Arabic numerals, a space,
+% and the section name with no special decoration\footnote{According to
+% the popular, oft-referenced \ac{OWL}: \citeurl{owlmla}.}.
+%
+% However, for the sake of clarity, the section headings in this class

+% To the user, \Dlst{itemize} and \Dlst{enumerate} lists
+% will function exactly as expected.
+% However, the formatting of the lists must be modified as to
+% preserve double-spacing and adhere to
+% common practice\footnote{According to the \ac{MLA} itself:
+% \url{https://style.mla.org/vertical-lists-in-mla-style/}.};
+% these changes are acheived using the \Dpkg{enumitem} package.

+% \subsection{Block quotation}
+% \label{sec:block_quoatation}
+%
+% \begin{environment}{blockquote}
+% The \citetitle{mlahb} dictates blockquotes be set flush a half-inch

+% \subsection{Figures and tables}
+% \label{sec:figures}
+%
+% The \citetitle{mlahb} doesn't specify much of anything about

+% so the following is mostly based on the package author's
+% personal preference and observations.

+%
+% Centered figures with margins the equivalent of one line of text
+% seems customary and logical.

+% Thanks to a bug inherited from the \Dpkg{here} package
+% which has remained unfixed since 1987\footnote{See the \cs{par}
+% on p. 11, line 249 of \Dfile{ltfloat.dtx} from the \LaTeX\ kernel.},
+% there is not only extra space after the figure but the inability to
+% insert a figure within a paragraph.
+% Miraculously, there is a fix for this\footnote{See David Carlisle's
+% answer on \TeX\ \acs{SE}:
+% \url{https://tex.stackexchange.com/a/310793}}.

+%
+% To correctly format endnotes per common practice\footnote{According
+% to the popular, oft-referenced \ac{OWL}: \citeurl{owlendnotes}.},
+% a custom \Dlst{mlanotes} list type will be created.
+% This is acheived with the \Dpkg{enumitem} package.
+%
+% \begin{macrocode}
+\newlist{mlanotes}{description}{1}
+\setlist[mlanotes]{%
+ parsep=0pt,
+ itemsep=0pt,

+ leftmargin=\MLA@indent
+}
+% \end{macrocode}
+%
+% The following initializes the \Dpkg{enotez} package to use
+% the \Dlst{mlanotes} list format.
+%
+% \begin{macrocode}
+\DeclareInstance{enotez-list}{mla}{list}{%

+% \end{macrocode}
+% \end{environment}
+%
+% The \citetitle{mlahb} prescribes a half-inch hanging indent
