% \section{Introduction}
% \label{int}
% 
% The \cls{udiss} bundle is a \LaTeX-class-file developed to
% assist students in typesetting their \emph{u}niversity
% \emph{diss}ertations. It is a collection of multiple
% support files. This is the first experimental version. We
% need feedback and comments from the community to make it
% better. Currently, nothing should be considered
% \enquote{stable}. Soon after getting comments and reviews
% from the community, we will move towards a stable version.
% 
% Universities often have strict requirements regarding the
% formatting of the dissertations/theses submitted to them.
% This bundle pre-supplies a generic style
% (university-agnostic) for creating dissertations. It can
% be loaded simply with:
% 
% \begin{verbatim}
% \documentclass{udiss}
% \end{verbatim}
% 
% But, apart from the generic style, it also supplies
% university or department specific files for some selected
% institutions. Each specialised class file comes
% with an identifier. E.g., if you want to use the template
% for the Kerala university, you may use the |ukerala| tag
% and load its template like in the following:
% 
% \begin{verbatim}
% \documentclass{udiss}
% \dissertationstyle{ukerala}
% \end{verbatim}
% 
% We are willing to expand. If you want your institution to
% be supported by us, please have a look at the instructions
% given in \cref{req}. If you want to develop your own
% style, please have a look at the developer's instruction
% given in \cref{dev}. If you want to get your class
% published under this bundle, please have a look at the
% contribution guidelines given in \cref{con}.
% 
% This document explains the user interface as well as the
% implementation of the class. It has three major parts.
% The first one contains the documentation of the class
% (\cref{doc}), the second one contains the developer's
% manual (\cref{dev}) and the third one contains the
% implementation of it (\cref{imp}).
% 
% Before getting started with the documentation, just a
% brief note about our approach. As of version 0.1, we are
% planning to have a radically all-modern and
% backwards-blind approach. This is a Unicode-only package,
% meaning, it won't work with the classic PDF\LaTeX. We load
% the modern, well maintaned and inclusive implementation of
% the Latin Modern family, i.e., the New Computer Modern
% family (\url{ctan.org/pkg/newcm}). For using/testing the
% class, please use the latest \TeX\ Live (all packages
% updated, as of 2024-09-27). Both \hologo{XeLaTeX} and
% Lua\LaTeX\ supported, but the latter is recommended as it
% identifies scripts without markup.
% 
% \section{Documentation}
% \label{doc}
% 
% This part of the document describes everything that a
% normal user of this class should know. It enlists all the
% features of the class.
% 
% \subsection{User manual}
% 
% Since this is a class that typesets dissertations, it
% requires some basic information which is provided using
% the following macros.
% 
% We provide the usual \LaTeX-like macros for the
% convenience, but these macros have
% \emph{key-value}-equivalents as well.
% 
% \begin{function}{\title,\author,\pronouns}
%   \begin{syntax}
%     \cs{title}\marg{the-title-of-the-dissertation}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%     \cs{author}\marg{name-of-the-author}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%     \cs{pronouns}\marg{the-pronouns-of-the-author}
%   \end{syntax}
%   Like in most standard \LaTeX\ classes, |\title|
%   command saves the title of the dissertation from its
%   argument. This is one of the commands which we mark as
%   \emph{strict}. In the manual, all such commands are
%   marked with a
%   {\footnotesize\faIcon{exclamation-triangle}} symbol at
%   the right end. If such commands (or their parametric
%   equivalents as shown in the following paragraph) are not
%   provided, the compilation is interrupted with an error.
%   The |\author| command doesn't return any error if the
%   class option |blind| is loaded. Since the |blind| option
%   is used for anonymous submissions, the author
%   information is irrelevant anyways and hence, is ignored.
%   
%   These macros are available as class options too. One
%   just has to use |title=|\marg{title} in the optional
%   argument of the |\documentclass| command. Similarly,
%   |author| and |pronouns| also are available.
% \end{function}
% 
% \begin{function}{\subtitle,\shorttitle}
%   \begin{syntax}
%     \cs{subtitle}\marg{the-subtitle-of-the-dissertation}
%     \cs{shorttitle}\marg{a-short-title-for-headers}
%   \end{syntax}
%   Dissertations often have a subtitle too, but it is not
%   an absolute requirement, so optionally, one may want to
%   use |\subtitle| command. Sometimes the title and the
%   subtitle are too long for the running header. One may
%   provide a short title with |\shorttitle| for this
%   purpose. Depending on the selected template and options,
%   it will be printed.
%   
%   These commands are also available as class options
%   |subtitle| and |shorttitle|.
% \end{function}
% 
% \begin{function}{\stream,\discipline,\degree}
%   \begin{syntax}
%     \cs{stream}\marg{the-name-of-the-stream}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%     \cs{discipline}\marg{the-name-of-the-discipline}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%     \cs{degree}\marg{the-name-of-the-degree}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%   \end{syntax}
%   These details are used at several places in the class.
%   E.g., the declaration, the \enquote{fulfilment}
%   statement printed on the first page. Like most other
%   macros, these too have straight forward
%   \emph{key-value}-equivalents |stream|, |discipline| and
%   |degree|.
% \end{function}
% 
% \begin{function}{\supervisor,\university,\department}
%   \begin{syntax}
%     \cs{supervisor}\marg{name-of-the-supervisor}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%     \cs{university}\marg{name-of-the-university}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%     \cs{department}\marg{name-of-the-department}^^A
%     \ignorespaces\hfill^^A
%     {\footnotesize\faIcon{exclamation-triangle}}
%   \end{syntax}
%   These commands are not seen in other standard
%   \LaTeX-classes, but \cls{udiss} requires them
%   obligatorily (only except in the |blind| mode).
%   
%   |supervisor|, |university| and |department| are the
%   \emph{key-value}-equivalents.
% \end{function}
% 
% \begin{function}{\logo,\logo*}
%   \begin{syntax}
%     \cs{logo}\marg{file-name}
%     \cs{logo*}\marg{\TeX-code}
%   \end{syntax}
%   Some departments mandate printing the university logos
%   in the dissertation. If this command is used, the logo
%   is printed. The location of the logo can be customised
%   as per the requirement. The class provides options for
%   that.
%   
%   If you are mad about \TeX\ and have a code for printing
%   the logo of your institute, use this command with a star
%   and in its argument, paste your code to get it printed
%   at an appropriate place.
%   
%   We have |logo| and |logo*| as the
%   \emph{key-value}-equivalents.
% \end{function}
% 
% \begin{function}{language,ldfbabel,nofontwarning}
%   \begin{syntax}
%     |language|=\marg{babel-language-names}
%     |ldfbabel|=\marg{babel-ldf-language-names}
%     |nofontwarning|=\marg{truth-value}\udissfval
%   \end{syntax}
%   The \pkg{babel} package has a complex mechanism for
%   loading languages. The complex design has its own
%   advantages, especially with regards to backwards
%   compatibility. For detailed explanation, it's best to go
%   through the user manual of \pkg{babel}, or its official
%   online documentation, especially the web-page at:
%   \url{\babelurl}.
%   
%   To help those who are completely at sea, we briefly will
%   have a look at the two mechanisms \pkg{babel} provides.
%   One is the original method of loading the
%   language-name(s) as class option(s), so something like:
%   
%   \begin{verbatim}
%     \usepackage[italian,hindi,english]{babel}
%   \end{verbatim}
%   
%   The last one from the list is understood as the
%   \enquote{main} language of the document. These languages
%   are defined using the so-called |.ldf|-files. A lot of
%   support for some languages is available using this
%   mechanism. For some European languages, e.g., French,
%   the difference between the two mechanisms is too sharp
%   and it has been found that a lot of native speakers
%   still prefer the old, stable way of using |.ldf|-files.
%   If you are one of them and you are used to loading
%   language-names as options to package \pkg{babel}, you
%   should use the |ldfbabel| option of \cls{udiss}. But we
%   advise against it.
%   
%   The second approach provided by \pkg{babel} for loading
%   languages is as follows:
%   
%   \bigskip
%   |\babelprovide|\marg{language-name}
%   \bigskip
%   
%   This method follows and uses the Unicode Common Locale
%   Data Repository (CLDR) for creating the resources. This
%   data is saved in |.ini| files. This is a more modern
%   approach, in our opinion. But it may cost us a little
%   bit of inconvenience since it doesn't support the common
%   short-hands which are provided by the |.ldf| files. But
%   short-hands make the input more and more \TeX-dependent
%   and thus less productive, so we don't endorse it. That
%   is why the more intuitive name for language-options in
%   this class is for the |.ini|-based approach. We load the
%   |english| language by default if no other is loaded. For
%   this too, we go with the |.ini| file developed for
%   English.
%   
%   The syntax of both these options is exactly like the one
%   provided by \pkg{babel}. One may provide a
%   comma-separated list and the last one of them will be
%   set as the main language of the document. Have a look at
%   \cref{dev} for more details regarding this.
%   
%   We also provide some auxiliary \TeX\ files with the
%   class for setting the font-families as well as the
%   language-specifics as required by \pkg{babel}. If a file
%   like that it is not found, we issue a warning. If the
%   users want that warning to be silent, they can use the
%   option |nofontwarning|.
% \end{function}
% 
% \begin{function}{license,copyright-yrs,localcopyright}
%   \begin{syntax}
%     |license|=\marg{all-rights-reserved/CC-BY-SA/GFDL}^^A
%     \udissarr
%     |copyright-yrs|=\marg{copyrightable-years}\hfill^^A
%     {\color{udisslink}|\the\year|}
%     |localcopyright|=\marg{the-word-for-copyright}^^A
%     \hfill{\color{udisslink}|Copyright|}
%   \end{syntax}
%   This is an option to set a license for the dissertation.
%   We encourage users to use free culture licenses.
%   Currently we support two popular licenses, i.e.,
%   \enquote{CC-BY-SA 4.0+ International} and \enquote{GFDL
%     v1.3+}. We don't set any license by default as we
%   believe making a work \enquote{free} (as in freedom)
%   should be the decision of the author and hence
%   \enquote{all rights are reserved} by default. If you are
%   not using the |blind| package option, your output will
%   have a copyright notice with your (author's) name and
%   the current year as the copyrightable year in the
%   metadata of the PDF. If you are wondering why, the
%   |blind| option is for preserving the anonymity of the
%   author and the copyright-notices require a
%   copyright-holder by default, thus with |blind| option,
%   we have disabled choosing licenses. If you want to
%   change the copyrightable year(s), you may use the option
%   |copyright-yrs|. Since the package is supposed to
%   support multilingual typesetting, we have provided an
%   option to change the word \enquote{Copyright} to the one
%   in the main language of your document.
% \end{function}
% 
% \begin{function}{placeholders}
%   \begin{syntax}
%     |placeholders|
%   \end{syntax}
%   If you want to see how the things so far discussed come
%   together, you may just load this option. It places
%   placeholders for all the options discussed for creating
%   a sample document.
% \end{function}
% 
% \begin{function}{^^A
%   lot,lof,declaration,declarationtxt,decllocal^^A
% }

%   By default, the class only prints the table of contents.

%   These are boolean keys which take either |true| or
%   |false| as their values. Not passing any truth-value to
%   a |key| is equivalent to using |key=true|. Similarly,
%   many universities require a declaration from the
%   candidate regarding the originality of the work. We have
%   provided a sample draft of the declaration in a
%   renewable macro, but it is not enabled by default. After
%   getting comments from the community, we will decide what
%   should be done with it. Note that the default value for

%     Throughout the documentation, at the right corner, we
%     enlist the possible values to a key and the default
%     one is marked in red.^^A
%   }. Declaration text can be edited using |declarationtxt|
%   option. The local word for declaration is stored in

%   \end{syntax}
%   Many departments require the submissions to be made in
%   the print form as well. For that, |print| is a boolean
%   option. It creates outputs suitable for the print
%   submissions. The class, by default, does not use |print|
%   option. The default output of the class is suitable for
%   digital submissions. The following settings are always
%   turned on by the class in normal circumstances:
%   
%   \begin{itemize}
%   \item The \pkg{hyperref} package is loaded.
%   \item The \pkg{xcolor} package is loaded. Some colours
%     for the internal cross-references are pre-selected.
%   \end{itemize}
%   
%   If you don't want colours for the hyperlinks in your
%   digital document, you may use the |norefcolors|
%   option. If you don't like the pre-defined colour-scheme
%   given by us for the digital documents, you may use the
%   class options specifically developed for changing them.
%   They are |udisslinkclr|, |udissurlclr| and
%   |udissciteclr|. The arguments of these options are
%   either the pre-defined colours by package |xcolor| or
%   user-defined colours with the |\colorlet| or
%   |\definecolor| commands. The default colour-scheme
%   used by us is as seen in the macro explanation above.
%   
%   More importantly though, if a PDF with colours is given
%   for printing and the printer is using the black and
%   white mode, then the coloured words look faded in the
%   print out. To avoid this, we load the \pkg{xcolor}
%   package only when the |print| option is \emph{not}
%   loaded (basically always, by default). For performance
%   reasons, we don't load  the |hyperref| package when
%   |print| is loaded. Hyper-references make sense only in a
%   digital PDF, so to optimise PDF compilation, in |print|
%   mode, we don't load |hyperref|.
% \end{function}
% 
% Note that if you are using the |license| option with
% |CC-BY-SA|, the \pkg{doclicense} package |\Require|d for
% printing the license automatically loads the
% \pkg{hyperref} package. We don't have any control over it
% and hence, you will see the hyperlink boxes around the
% CC-text. You can safely ignore them as the text is still
% in black colour and your objective is anyways just to
% \emph{print} the output.

%   \begin{syntax}
%     |oldstylenumoff|=\marg{truth-value}\udissfval
%     |oldone|=\marg{truth-value}\udissfval
%   \end{syntax}
%   In text, the old style numbers look better. The numbers
%   in the current document are old style. Lining numbers,
%   on the other hand, don't have ascenders and descenders.
%   
%   If you prefer the lining numbers, you may turn this
%   option on and all the fonts will start showing lining
%   numbers. Note that printing of old style numbers also
%   depends upon whether the font has old style numbers or
%   not. The relevant settings are added to the font
%   automatically, but while selecting the font, first make
%   sure whether the old style table is present or not.
%   
%   Apart from that, the New Computer Modern font family
%   provides an old-style shape for the number 1 (this exact
%   shape!), but this shape is provided as a character
%   variant and character variants cannot be loaded
%   globally, since various fonts may have various variants
%   at that slot, hence if someone wants this shape, they
%   will have to use the |oldone| option. Without this
%   option the number looks like as seen on the first line
%   and that's the default style of \cls{udiss}.

% for linguistic support, \pkg{fontspec} and
% \pkg{unicode-math} package for loading fonts. It's the
% best to not load them again. For loading languages, it's
% best to use the package internal mechanism. If you find
% something missing in the mechanism, you may load
% \pkg{babel} or \pkg{fontspec} commands directly. Please
% consider reporting a missing feature so that we can
% implement it in the future versions.
% 
% We will see two examples of loading languages.

% As the section title and the double bend suggests, this
% area is for advanced customisation. Only enter it if you
% have sufficient confidence to avoid errors.
% 
% 
% \subsubsection{Fonts}
% 
% We are a Unicode-only class, so we need to take care of
% three major font families, i.e., Roman,
% \texttt{Typewriter} and \textsf{Sans} (stylisation
% intentional, for demonstration). The \pkg{fontspec}
% package takes care of Unicode fonts in \LaTeX, but we,
% additionally, load package \pkg{unicode-math} too, to set
% math-fonts. Even though, this much is practically enough
% for font-selection, we go with the \pkg{babel}'s mechanism
% of loading language-specific fonts, so that the fonts
% don't apply globally. Our class already takes care of most
% of the requirements regarding font, but if you want to
% tinker with the defaults, you are advised to read this
% section. The following parameters are for you.
% 
% \begin{function}{explicitext,ignorefsoff}
%   \begin{syntax}
%     |explicitext|=\marg{truth-value}\udissfval
%     |ignorefsoff|=\marg{truth-value}\udisstval
%   \end{syntax}
%   Without this option, one cannot use the |Extension|
%   parameter of package \pkg{fontspec}/\pkg{unicode-math}.
%   We have some options later which set the extension for
%   |rm|, |sf| and |tt| families. They are also useless if
%   this key is not used. A word of caution: loading
%   explicit extensions for fonts is restrictive. Suppose
%   you want to use KpRoman-Regular as your normal font,
%   but, say, FreeSerifBold as your bold font (please don't,
%   this is solely for exemplification :P), loading an
%   explicit extension will cause errors as the former is an
%   OpenType font and the latter is a TrueType one. So if
%   you are 200\% sure that all the fonts you need use one
%   particular extension \emph{only}, then use this option.
%   Otherwise, you are better off without it.
%   
%   The \TeX-tree contains many files having the
%   |.fontspec| extension. These files contain predefined
%   settings for fonts which the users may not always want.
%   Thus, we ignore these files by default. If you are very
%   sure that you want to load |.fontspec| files, you may
%   turn our conditional off and the |.fontspec|-files, will
%   be loaded correctly.
% \end{function}
% 
% \begin{function}{^^A
%   rmfeatures,sffeatures,ttfeatures,mathfeatures^^A
% }
%   \begin{syntax}
%     |rmfeatures|=\marg{font-features-for-serif-fonts}

%     |ttfeatures|=\marg{font-features-for-mono-fonts}
%     |mathfeatures|=\marg{font-features-for-math-fonts}
%   \end{syntax}
%   We have |udiss|-options for most commonly used optional
%   parameters of fonts, still there are a lot of them
%   available which we didn't consider important for the
%   purpose of this class, e.g., |Scale|, |Color|. If you
%   want to use these features with your fonts, you may use
%   these four options as per your need. The value of this
%   key is directly injected in the font-loading commands.
% \end{function}
% 
% \begin{function}{rmfntext,sffntext,ttfntext,mathfntext}
%   \begin{syntax}
%     |rmfntext|=\ignorespaces^^A
%     \marg{font-extension-for-serif-fonts}\ignorespaces^^A
%     \hfill\texttt{ttf\,\textbar\,otf}
%     |sffntext|=\ignorespaces^^A
%     \marg{font-extension-for-sans-fonts}\ignorespaces^^A

%     \marg{font-extension-for-math-fonts}\ignorespaces^^A
%     \hfill\texttt{ttf\,\textbar\,otf}
%   \end{syntax}
%   With these four options, one may choose either
%   |ttf| or |otf| extension for a particular font family.
%   As mentioned before, it applies to all the fonts loaded
%   in that family. Note that these options are only used
%   when the |explicitext| option is active. This is why
%   there is no default value set. By default this explicit
%   extension method itself is not used.
% \end{function}

% If you want to know the default fonts we load always with
% \cls{udiss}, you may refer to \cref{udissenfonts}.

% the code in this central |.dtx| file.
% 
%    \begin{macrocode}
%&lt;*class&gt;
%    \end{macrocode}
% 
% First we declare the class with some elementary
% information.
% 
%    \begin{macrocode}
\ProvidesClass{udiss}[2024/10/01 v0.1
  A LaTeX bundle for typesetting dissertations (TUGIndia)]
%    \end{macrocode}
% 
% We develop the options for the class using
% |\ekvdefinekeys| command. This command is provided by the
% \expkvlogo{def} package, whereas for creating
% class/package options, we use the \expkvlogo{opt}
% package. For performance reasons, we don't use the entire
% \expkvlogo{bundle}.
% 
%    \begin{macrocode}
\RequirePackage{expkv-def,expkv-opt}
%    \end{macrocode}
% 
% \begin{macro}{\pronouns,pronouns}
%   Mostly we have implemented the macros in the same order
%   as they are documented, but the exception is of the
%   first two, i.e., |\title| and |\author|. These commands
%   are developed by the standard classes too and hence,
%   after loading the class (\cls{memoir} in our case) their
%   definitions are rewritten. Thus these two macros are
%   developed a little late in the code. Rest is still in
%   line with the documentation. The method of saving the
%   values of the macros is an indirect one. We use internal
%   macros (e.g., |\udiss@title|) for saving them.
%   
%   We start with the |pronouns| field. Since it is
%   optional, we don't need any errors here. At each step,
%   we set some if-conditionals. All of them follow the
%   standard convention of prefixing the class/package name
%   and the |@| symbol for internalising. Have a look at the
%   following two conditionals which we use immediately
%   while defining the |pronouns| field:
%   
%    \begin{macrocode}
\newif\ifudiss@pronouns
\newif\ifudiss@blind
%    \end{macrocode}
%   
%   We use the \pkg{xparse}-syntax for developing user-side
%   macros. First we check if the class option |blind| is
%   loaded. If it is so, there is no point in saving
%   |pronouns|, hence it is skipped. The following code does
%   that:
%   
%    \begin{macrocode}
\NewDocumentCommand{ \pronouns }{ m }{%
  \ifudiss@blind
  \else
    \def\udiss@pronouns{#1}%
  \fi
}
%    \end{macrocode}
% 
%   As mentioned before, we use \expkvlogo{def} and
%   \expkvlogo{opt} packages for developing the
%   \emph{key-values}. The former proives a command
%   |\ekvdefinekeys| that defines all the \emph{key}s. We
%   could have called it just once in the code and developed
%   all the \emph{key}s at one go, but in order to keep the
%   implementation in line with the documentation and for a
%   generally better readable code, we segment it in several
%   pieces and develop the respective options with different
%   calls of |\ekvdefinekeys|. Note that the set used for
%   all of them is still the same, i.e., |udiss|. Storing a
%   value passed to a key in a specific macro for later use
%   is quite straight-forward in \expkvlogo{def}, but since
%   we need to set some macros conditionally, we will use
%   the |code| \emph{type} of \expkvlogo{}. The first
%   non-space-token followed by the invocation of this type
%   is the name of the \emph{key}. Its argument is an
%   arbitrary \TeX-code where we can use have the usual
%   \TeX-argument-call, i.e., |#1|.
%   
% 
%    \begin{macrocode}
\ekvdefinekeys{udiss}{%
  code    pronouns       = {%
    \ifudiss@blind
    \else
      \def\udiss@pronouns{(#1)}%
    \fi
    \udiss@pronounstrue
  }%
}
%    \end{macrocode}
% \end{macro}
% 
% The |\ifudiss@blind| conditional was developed in order to
% conditionally save (and print) some information which
% identifies the author. If a user loads the option |blind|,
% they don't need that information to be printed and since
% it is not supposed to be printed, why to even save it?
% Thus we save it only when needed.
% 
% \begin{macro}{title,author}
% 
%   Since we don't allow blank arguments for \emph{strict}
%   commands/parameters, we check their existence there and
%   there and generate an error if found blank. Since we
%   need to error twice (once with the macro, once with the
%   parameter, we save the code for generating the error in
%   a handy internal macro. Let's have a look at one
%   developed for the |title| field.
%   
%    \begin{macrocode}
\newif\ifudiss@title
\def\udiss@blank@title@err{%
  \ClassError{udiss}{%
    The `title' field cannot be blank%
  }{%
    You have provided an empty argument to the `title'
    field. This is not\MessageBreak permitted by the class.%
  }%
}
%    \end{macrocode}
% 
%   We use the same method for all the other \emph{strict}
%   commands too.
% 
%    \begin{macrocode}\newif\ifudiss@author
\def\udiss@blank@author@err{%
  \ClassError{udiss}{%
    The `author' field cannot be blank%
  }{%
    You have provided an empty argument to the `author'
    field. This is not\MessageBreak permitted by the class.%
  }%
}
%    \end{macrocode}
% 
%   Now we start developing the code for the |title| and
%   |author| parameters. In order to check whether a macro
%   is empty or not, we need to use the
%   |\ifx\macro|$_{1}$|\macro|$_{2}$ construct. But since
%   we have an argument and not a ready macro for
%   comparison, we first we develop an internal macro with
%   the argument as its value.
% 
%    \begin{macrocode}
\ekvdefinekeys{udiss}{%
  code    title          = {%
    \def\udiss@tmp@title{#1}%
%    \end{macrocode}
% 
%   The true branch of this conditional, i.e., everything
%   till either |\else| or |\fi| is found, defines the
%   actual macro to be used while typesetting, i.e.,
%   |\udiss@title|, but since the user has provided a blank
%   macro, we give a cryptic value to the macro, e.g.,
%   |-NoValidTitle-|. Note that this gets printed in the
%   document even though the user gets an error. Since we
%   use this regularly, a user may search for |-NoValid| in
%   the output to find out all the values they missed
%   providing.
% 
%    \begin{macrocode}
    \ifx\udiss@tmp@title\empty
      \def\udiss@title{-NoValidTitle-}%
%    \end{macrocode}
% 
%   After this, we print the error for the blank argument.
%   In the |\else| branch (which means the user did
%   \emph{not} pass a blank argument, but provided a
%   legit value), we define the command with the actual
%   user-given-value. This is the most ideal condition.
% 
%    \begin{macrocode}
      \udiss@blank@title@err
    \else
      \def\udiss@title{#1}%
    \fi
  },%
%    \end{macrocode}
% 
% We repeat the same pattern for the \emph{strict} commands
% now. Here is the code for |author|.
% 
%    \begin{macrocode}
  code    author         = {%
    \def\udiss@tmp@author{#1}%
    \ifx\udiss@tmp@author\empty
      \def\udiss@author{-NoValidAuthor-}%
      \udiss@blank@author@err
    \else
      \def\udiss@author{#1}%
    \fi
  }%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{subtitle,\subtitle,shorttitle,\shorttitle}
%   Here is the code for the |subtitle| and |shorttitle|
%   fields. As they aren't \emph{strict}, no errors needed
%   for them. We need a conditional though. We set it to
%   true so that it is understood that this field was not
%   forgotten by the author. Only if their value is true, we
%   print them later.
%   
%    \begin{macrocode}

% \begin{macro}{logo,logo*}
%   \expkvlogo{} doesn't have a way to have starred

%   
%    \begin{macrocode}

}
%    \end{macrocode}
% \end{macro}
% 
% Now we move to the complicated task of developing the
% mechanism for loading languages. In order to imitate the
% syntax of |babel|, we need a parser which inteprets
% comma-separated language-names. We develop a new counter
% called |udiss@langbabel| and use it with |\alph| inside
% |\csname| in order to produce an ordered sequence of
% macros that store the different language-names. After
% parsing, the language macros should look like
% |\udiss@langbabel@a|, |\udiss@langbabel@a| etc. The
% following code does that. The |\udiss@lgbbl| macro is the
% internal parser for the language-names.
% 
%    \begin{macrocode}
\newcounter{udiss@langbabel}
\stepcounter{udiss@langbabel}
\def\udiss@int@langbabel#1{%
  \expandafter\edef
    \csname
      udiss@langbabel@\alph{udiss@langbabel}%
    \endcsname{#1}%
  \stepcounter{udiss@langbabel}%
}
\NewDocumentCommand\udiss@lgbbl{ &gt;{ \SplitList{,} } m }{%
  \ProcessList{#1}{\udiss@int@langbabel}%
}
%    \end{macrocode}
% 
% \begin{macro}{language,ldfbabel,nofontwarning}
%   We first create the if-conditionals required for this
%   job.
%   
%    \begin{macrocode}
\newif\ifudiss@lg@used
\newif\ifudiss@ldfbabel
%    \end{macrocode}
% 
%   The |language| key takes the comma-separated list as its
%   argument and passes the list to the |\udiss@lgbbl|
%   macro which we just saw. So whenever we pass multiple
%   languages to the option |language|, it is parsed by
%   |\udiss@lgbbl|. We then turn the |\ifudiss@lg@used|
%   conditional on, so that when neither of these options
%   are used by the user, we can do something. 
% 
%    \begin{macrocode}
\ekvdefinekeys{udiss}{%
  code    language       = {%
    \udiss@lgbbl{#1}%
    \udiss@lg@usedtrue
  },%
%    \end{macrocode}
% 
%   On the other hand though, the process is quite simple
%   and straight forward. We need to store the list of the
%   |.ldf|-languages in a macro and later pass it to the
%   \pkg{babel} package as \pkg{babel} already understands
%   how to parse it. We store the list in the
%   |\udiss@ldfbabel@list| macro. With this option, we have
%   to turn an additional conditional on, i.e.,
%   |\ifudiss@ldfbabel|. Usually we don't use the |.ldf|
%   mechanism at all as mentioned in \cref{doc}.
% 
%    \begin{macrocode}
  code    ldfbabel       = {%
    \def\udiss@ldfbabel@list{#1}%
    \udiss@lg@usedtrue
    \udiss@ldfbabeltrue
  },%
%    \end{macrocode}
% 
% The |nofontwarning| option is developed using the
% |invbool| \emph{type} which creates (or uses, if present)
% a conditional and sets it to true. In this case, it is
% |\ifudiss@font@warning|. Unless the option |nofontwarning|
% is used, the aforementioned condition is true.
% 
%    \begin{macrocode}
  invbool nofontwarning  = {\ifudiss@font@warning}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{license,copyright-yrs,localcopyright}
%   Now we develop the options for setting a license with
%   the legit copyrightable years. As usual, we first
%   develop the required conditionals.
%   
%    \begin{macrocode}
\newif\ifudiss@free@culture
\newif\ifudiss@ccbysa
\newif\ifudiss@gfdl
%    \end{macrocode}
% 
%   We use a new \expkvlogo{} \emph{type}s for license which
%   is |choice|. It takes a definite list of |choice|s that
%   run some arbitrary code. We define an internal macro
%   |\udiss@license@notice| which holds the notice text of
%   the selected licenses. We set the
%   |\ifudiss@free@culture| conditional to true if the
%   user's |choice| is |CC-BY-SA| or |GFDL|. Why we do this
%   is because if the choice is |all-rights-reserved|, it
%   need not be explicitly mentioned. It is always assumed.
%   Also, it is seen in PDF's metadata. For this, we enable
%   the conditional. Using the |initial| \emph{prefix} of
%   \expkvlogo{}, we set the |all-rights-reserved| as the
%   default choice of users.
% 
%    \begin{macrocode}
\ekvdefinekeys{udiss}{%
  choice  license        = {%

%   We defined most other commands as per the flow of the

%   did so because these commands are defined by the

%   the memoir class (which we just loaded), the commands
%   would have got renewed after loading the class and thus
%   our internal macros would have failed. On the other
%   hand, we could not have loaded the memoir class in the
%   beginning, because we use the |\ifudiss@print|
%   conditional, i.e., developed with the help of
%   \expkvlogo{def} package. Even if we had separated the
%   code of |print| key, it would have been necessary to
%   process the keys using |\ekvoProcessGlobalOptions|, but
%   we could not have done that since there were a lot of
%   other options pending. This is why, we develop the
%   |\title| and |\author| commands now.

%    \end{macrocode}
% 
% We require the \pkg{babel} package for loading the
% language settings. We have the following three situations
% with loading languages in \cls{udiss}:
% 
% \begin{enumerate}
% \item Users don't load any of the language options at all.
% \item Users load languages with option |ldfbabel|.
% \item Users load languages with option |language|.
% \end{enumerate}
% 
% If a user has used |ldfbabel|, then the macro which stores
% the language-list is directly passed to the package using
% |\PassOptionsToPackage|.
% 
%    \begin{macrocode}
\ifudiss@lg@used
  \ifudiss@ldfbabel
    \PassOptionsToPackage{%
      \udiss@ldfbabel@list
    }{babel}%
  \fi
%    \end{macrocode}
% 
% If user hasn't loaded any language options, we assume that
% they have no intent to load languages that require |.ldf|
% files and hence we mandate loading |.ini| files for all
% the languages. In addition to that, we load |english| as
% the main language. This takes care of the first two
% situations.
% 
%    \begin{macrocode}
\else
  \PassOptionsToPackage{english,provide*=*}{babel}%

% 
% We also load package \pkg{iflang} for testing
% language-names.
% 
%    \begin{macrocode}
\RequirePackage{iflang}
%    \end{macrocode}
% 
% First we check if the user has loaded |ldf| languages. We
% ignore that branch completely. If it is not loaded and
% they have loaded exactly one language, then we set that
% language as the main language. Note that when user uses
% one language, the value of the counter is 2 as it is
% increased by the counter each time.
% 
%    \begin{macrocode}
\newcounter{udiss@tmp@langcnt}
\ifudiss@ldfbabel
\else
  \ifudiss@lg@used
    \ifnum\theudiss@langbabel=2\relax
      \addtocounter{udiss@langbabel}{-1}%
      \ifLuaTeX
        \babelprovide[%
          main,%
          import,%
          onchar                 ={ids fonts}%
        ]{%

        }%
      \fi
    \fi
%    \end{macrocode}%
% 
% When users use multiple languages, the situation is a bit
% more complicated. Because the parser parses and increases
% the counter each time. Suppose, the user provided 5
% languages, the parser will create 5 macros \emph{and}
% increase the counter for one last time resulting in the
% value 6. In order to stop processing when the number of
% actually used languages is reached, we need to store the
% current number \emph{minus one} because of this. We have
% to start a loop from value 1 till it reaches the last
% value. For this, we reset the counter. In order % to stop
% when all the languages are parsed, we need to remember the
% actual value of the counter somewhere. Hence we create a
% temporary counter for this and equate it with the value of
% our actual counter minus 1. Note that we escape
% |\ifudiss@ldfbabel| too. Now we start the calculation when
% the counter's value is 3 or more, basically the author has
% to use at least two languages in order to activate the
% loop ahead.
%   
%    \begin{macrocode}
    \ifnum\theudiss@langbabel&gt;2\relax
      \setcounter{udiss@tmp@langcnt}{%
        \numexpr\theudiss@langbabel -1\relax
      }%
%    \end{macrocode}
% 
% We now can safely manipulate our actual counter. Starting
% from the first language, we load all of them with the
% |\babelprovide| command. We reset the counter to 1:
% 
%    \begin{macrocode}
      \setcounter{udiss@langbabel}{1}%
%    \end{macrocode}
% 
% Now we start a loop.
% 
%    \begin{macrocode}
      \loop
%    \end{macrocode}
% 
% Only Lua\LaTeX\ supports the |ids fonts| parameter with
% |\babelprovide| for applying fonts to the input text with
% respect to their Unicode slots. That is why we start the
% |\ifLuaTeX| conditional and load the |onchar| option.
% Loading a conditional inside |\babelprovide| wasn't
% permitted because of expansion, hence we load the entire
% command in the else branch. Notice that there is no space
% after the |=| sign of the |onchar| option. To know why,
% you may want to read this wonderful answer by Jonathan P.
% Spratte: \url{https://topanswers.xyz/tex?q=8039#a7652}.
% 
%    \begin{macrocode}
        \ifLuaTeX
          \babelprovide[%
            import,%
            onchar                 ={ids fonts}%
          ]{%
%    \end{macrocode}
% 
% Now we pass |\udiss@langbabel@a| as an argument to
% |\babelprovide| command (the value of the counter is as of
% now 1).
% 
%    \begin{macrocode}
            \csname
              udiss@langbabel@\alph{udiss@langbabel}%
            \endcsname
          }%
%    \end{macrocode}
% 
% We start the |\else| branch and use the same thing again,
% just without the |onchar| option .
% 
%    \begin{macrocode}
        \else
          \babelprovide[import]{%
            \csname
              udiss@langbabel@\alph{udiss@langbabel}%
            \endcsname
          }%
        \fi
%    \end{macrocode}
% 
% Woohoo! We loaded the first language successfully. Now, we
% increment the counter, but there is another situation
% which we have to take into account. What if the user just
% loaded a single language with the |language| option? The
% loop will run into trouble, that's why we only run the
% loop if the value of the total number of languages is more
% than one. We had saved it in a temporary counter.
% 
%    \begin{macrocode}
        \ifnum\theudiss@tmp@langcnt=1\relax
        \else
          \addtocounter{udiss@langbabel}{1}%
        \fi
%    \end{macrocode}
% 
% Now the value of the counter is 2 which means the second
% language. We need to again load the same settings for it,
% but we can't keep doing this manually since 1) we are lazy
% (the most important) 2) we have no idea how many languages
% the user has loaded, so now we actually activate the
% |\loop| that we had started with the |\repeat| command. It
% runs all the commands seen after the |\loop| command (this
% includes the one used for increasing the counter too) till
% the value of the counter is less than the value of
% |udiss@tmp@langcnt|. Remember we had already set it to the
% value of the original counter (before setting it to 1)
% \emph{minus one}. Now the next command will stop at one
% number even lesser than it as we have used the |&lt;|
% relation while comparing. Also, here we will close the
% if-conditional that checked if more than one languages
% were used or not.
% 
%    \begin{macrocode}
        \ifnum\theudiss@langbabel&lt;\theudiss@tmp@langcnt

%    \end{macrocode}
% 
% Are you wondering why we did this? Because we want to set
% the \emph{exact} last language as the |main| language! The
% current value of our counter at this point has that
% language. But remember we are out of the loop as well as
% the if-conditional. Thus we have to again consider the
% situation where user just passed one language. So far what
% we have done is load all the languages except the last one
% with |\babelprovide|. This includes the single-language
% case. Thus we need no further processing in that case. So
% we only parse the last pending language if the user had
% passed multiple languages. We start an if-conditional and
% keep its |if|-branch empty and write the rest in the
% |else|-branch.
% 
%    \begin{macrocode}
    \ifnum\theudiss@langbabel=1\relax
%    \end{macrocode}
% 
% We again use |\babelprovide|, but this time with |main|
