%% ---------------- Critical packages -----------------------------
\RequirePackage{etoolbox}% \newbool, \ifbool, etc.
%% Toolbox of many many macros that make a lot of latex code smarter and more robust
%% http://texdoc.net/texmf-dist/doc/latex/etoolbox/etoolbox.pdf
\RequirePackage{ifluatex} %% \ifluatex

%% ---------------- Boolean switches -----------------------------
%% Booleans make it easy to enable and disable parts of the template
\newbool{debug}
\newbool{draftbool}
\newbool{IS}
\newbool{proof}


%% ---------------- Declaration of Package Options--------------------
%% Remember that we have \AtEndOfPackage{}
%%     \AtBeginDocument{}, \AtEndDocument{}
%% If you want execution conditional on file existence
%%     \IfFileExists{filename}{true}{false}
%%     \InputIfFileExists{filename}{true}{false}
%% For error reporting
%%     \PackageError{class-name}{error-text}{help-text}

% Generalized settings
\DeclareOption{debug}{%
  \booltrue{debug}
  \typeout{ruthesis option: debug}%
  \typeout{DEBUG MODE ENABLED!  PREPARE FOR VERBOSITY!}}

\DeclareOption{draft}{\booltrue{draftbool}}

\DeclareOption{IS}{\booltrue{IS}}

\DeclareOption{forcegraphics}{%
  \PassOptionsToPackage{final}{graphicx}
  \PassOptionsToPackage{final}{pdfpages}
  \PassOptionsToPackage{final}{hyperref}
  %% add any other elements that should be included in draft
  \finalifforcegraphics{graphicx}%We have to catch graphicx early
  \setbool{forcegraphics}{true}\typeout{ruthesis option: forcegraphics}%
}%

%%% Memoir test: Memoir Manual 21.2 p.367
%% Only works with the memoir class!!!!!!!!!!!!!!!
\@ifclassloaded{memoir}{\let\endruthesis\relax}{\let\endruthesis\endinput
\PackageError{ruthesis}{The ruthesis package only works with the memoir class}%
{\@ehd}}
\endruthesis
%%---------------- Execution of Options -----------------------------
\ProcessOptions\relax% this stops searching for a * in \ProcessOptions*
%% Read page 20 of http://latex-project.org/guides/clsguide.pdf
%% carefully before modifying any of the execution and previous section.
%% ---------------- Package Loading -----------------------------

%% Now to print the status of all the booleans if debug boolean is set
%% Any boolean testing must be after the \LoadClass otherwise the Option execution
%% has not completed.
\ifbool{debug}{%
  \ifbool{forcegraphics}{\typeout{ruthesis bool: forcegraphics}}{}
  \ifbool{proof}{\typeout{ruthesis bool: proof}}{}
  \ifbool{debug}{\typeout{ruthesis bool: debug}}{}
}{}

%% ---------------- Internationalization -----------------------------
%% Unicode setup
\ifluatex\relax\else\RequirePackage[utf8]{inputenc}\RequirePackage[T1]{fontenc}\fi
% Font setup
% Standardized STIX2 fonts that print well, display on
% e-readers/screens clearly, and have compatible licensing
% requirements
\RequirePackage{stix2}
% allows UTF encoding, needed for Icelandic and other accented characters

\ifbool{IS}
{\RequirePackage[english,icelandic]{babel}}%%Icelandic main language
{\RequirePackage[icelandic,english]{babel}}%%English main language
%% Babel allows various automatic text to be in selected languages
%% But to use the options, you have to always load it, even for english
%% The languages must be specified in order.


\usepackage[useregional]{datetime2}
%% Smart manipulation of dates
\renewcommand{\date}[3]{\newcommand{\thedate}{\DTMdisplaydate{#1}{#2}{#3}{-1}}}

%% ---------------- Graphics ------------------------------
\RequirePackage{graphicx}
%% GraphicsX converts and includes graphics intelligently



%% ---------------- URLs and Paths -----------------------------
\PassOptionsToPackage{obeyspaces,spaces,hyphens,allowmove}{url}
\RequirePackage{url}
%% The url package typesets \url{} and unix file \path{} nicely.
%% Watch out that you leave a space after a last \ e.g. \path{C:\ }
%% Warning:  allowmove makes URLs not-fragile, so they can go in things that move
%%           If this breaks you will get very very weird errors
%% ---------------- Miscellaneous Packages ----------------------
%% ---------------- Fonts -----------------------------
%% Important:  The template has switched to STIX2 fonts and memoir defaults
%% to massively simplify font selection.  You should not need to mess with fonts.

%% ---------------- Main Code -----------------------------
