% \section{Introduction}
%
% This package implements the graphic identity of Universiteit Leiden for letters.
% Using these class files will make it easy for you to make and keep
% your letters compliant to this version and future
% versions of the graphic identity (``huisstijl'') of the university.
%
% If you think (1) that there is an error in compliancy with the house
% style, (2) that there is a feature missing in this class file, or
% (3) that there's a bug in this class file, 
% please, contact me through e-mail (|m.t.kreutzer@science.leidenuniv.nl|)
% about the issue.
% I'll provide you with an answer and if (and as soon as) possible
% with a solution to the problem you spotted.  
%
% \section{Synopsis}
% The |LEIletter| class is an extension of the standard KOMA-script letter
% class |scrlttr2|. It is intended to be used for writing business
% letters. It is compliant to the house style and allows for using
% windowed envelopes of the DL format, with right-aligned window. 
%
% The class requires and uses the following packages that are part of most 
% modern \LaTeX{} distributions: 
% \begin{itemize}
% \item the |graphicx| package to include the university logo.
% \item the |ifthen| package to process user options
% \item the |array| package to typeset a table on the front page
% \item the |babel| package to offer optional support for english
% \item the |regged2e| package for better left-justified text
% \item the |hyperref| package for formatting of hyperreferences
% \item the |textcase| package for better small capitals
% \item the |microtype| package for improved microtypography
% \item the |scrlayer-scrpage| package (part of KOMA-script)
% \item the |geometry| package for setting page margins
% \item the |setspace| package for setting interline distance
% \item the |lipsum| package for typesetting an example letter
% \end{itemize}
% and most importantly,
% \begin{itemize}
%   \item the |MinionPro| package and the Minion Pro fonts.
% \end{itemize}
% So make sure these packages are available to your
% \LaTeX{} compiler. The Minion fonts are commercial but easily 
% available: I was able to download the full set from 
%
% |https://www.wfonts.com/font/minion-pro|.  
% 
% Get a copy of the full font, preferably, and work 
% through the installation instruction in the |MinionPro| ReadMe file
% on CTAN.

% 
% \section{Usage}
% \begin{decl}
% \cs{documentclass}\oarg{options}|{LEIletter}|
% \end{decl}
% 
% \subsection{Language}
%
% \DescribeMacro{lang=<language>, dutch, english}
% The default language of the letters is Dutch, and without user input Dutch 
% will be selected. By providing option |lang=english| or simply by providing 
% the option |english|, the language will switch to english. Although not required, 
% the user can specify |dutch| or |lang=dutch| as an option. By switching to 
% English, all class-generated output will be in English and the document language
% switches to English, relevant for hyphenation and other language-specific 
% typesetting aspects. 
% 
% \subsection{Faculty}
%
% \DescribeMacro{faculty=<faculty>}
% The house style indicates that the name of the faculty is printed at the top
% right of the page, and below it the visiting address and postal address of the 
% faculty is given. These addresses were taken from the university website for 
% each of the faculties, and by specifying the faculty, the correct name and 
% address will be printed automatically. Note that it is still up to the user 
% to specify the name of the building. If needed, the visiting address and other 
% address details can be overwritten. 
%
% The following faculties are supported: |fwn| for Faculty of Science, |law| for 
% Faculty of Law, |med| for Faculty of Medicine, |fgw| for Faculty of Humanities, 
% |fsw| for Faculty of Social and Behavioural Sciences, |arch| for Faculty of 
% Archeology, |gga| for Faculty of Governance and Global Affairs. 
%
% If no value is specified, the letter defaults to |faculty=fwn|. 
%
% \subsection{Stationary with pre-printed logo}
%
% \DescribeMacro{briefdrager}
% By default, the class assumes that the letter will be printed on plain paper
% or by email. In that case, the logo of the university is included in the top
% left part of the paper. If stationary paper with pre-printed logo, called 
% `briefdrager' in the specification of the house style, is used, then the logo
% should not be printed. By specifying the option |briefdrager|, the logo is 
% suppressed. 
%
% \subsection{Letterhead information}
%
% \begin{decl}
% \cs{leilnumber}\marg{letter number} \\
% \cs{leilyourref}\marg{correspondence reference} \\
% \cs{leilsubject}\marg{letter subject}
% \end{decl}
%
% At the top of the letter, in the preamble before |\begin{document}|, these there
% items should be specified for inclusion in the reference line, along with the 
% date and other sender information. Note that the headings for the reference line
% can also be changed by the user -- see the code documentation for details. 
%
% \subsection{Loading of sender information}
%
% \DescribeMacro{author=<name>}
% The class offers the option to load a file that contains sender-information. 
% This file could be stored in a location that \LaTeX is able to find, such that 
% the same information need not be specified anew for each letter. See the example
% file |medewerker.lco| and the code documentation to set up such a file. To load 
% the file, the option |author=<name>| specifies that the file |<name>.lco| is
% loaded. 
%
% \begin{decl}
% \cs{leiltitle}\marg{academic titles} \\
% \cs{leilfirstname}\marg{sender first name} \\
% \cs{leillastname}\marg{sender last name} \\
% \cs{leilemail}\marg{sender email} \\
% \cs{leildirectphone}\marg{sender direct-call phone number} \\
% \cs{leilcontact}\marg{sender representative} \\
% \cs{leiljobtitle}\marg{sender job title} \\
% \cs{leilbuilding}\marg{sender office building} \\
% \cs{leilunit}\marg{sender organisational unit}
% \end{decl}
%
% These items can be specified for inclusion in the letterhead. Note that the 
% information for the letterhead line can also be set by the user by including 
% the relevant commands in the preamble. 
%
% \subsection{Structure of a letter}
%
% \begin{decl}
% \cs{begin}|{letter}|\marg{address}\ldots\cs{end}|{letter}| \\
% \cs{opening}\marg{salutation} \\
% \cs{closing}\marg{salutation} \\
% \cs{setkomavar}|{signature}|\marg{sender name and signature}
% \end{decl}
%
% The structure of the letter is an environment |letter|, where the opening
% statement includes the addresss of the recipient of the letter, on multiple
% lines separated by |\newline|. Opening and closing salutations have their own
% commands that take care of space before and after. All of this is taken from 
% the KOMAscript letter class that forms the basis of this class. This also holds
% for the signature. If the right user information is provided, then the signature
% defaults to title, first and last name of sender, and the job title on the line
% below. 
%
% If you want to change this, you can use cs{setkomavar}, for instance to
% include a scanned signature as follows 
% \begin{verbatim}
% \newcommand{\mSignature}{
%	\makebox[0pt][l]{\raisebox{-2cm}[0pt][2cm]%
%      {\hspace{-1.5cm}\includegraphics{krabbel.pdf}}}
% }
% ...
% \closing{\mSignature \unskip Best regards}
%\end{verbatim}	
% 
% for a scanned signature that is about 2 cm high.

%
% \subsection{option handling}
%
% We begin by setting up the processing of options using the |kvoptions| package,
% using |leil| as family name for all options and |leil@| as prefix for all tags. 
% The string option |lang| defaults to Dutch, |paper| defaults to A4, and |faculty|
% defaults to the Faculty of Science. the |\setkeys| command sets Dutch on A4 paper
% as default options. 
%
%    \begin{macrocode}
%<*class>
%    \end{macrocode}
%    \begin{macrocode}
\RequirePackage{ifthen}
\RequirePackage{kvoptions}
\SetupKeyvalOptions{family=leil, prefix=leil@}
\DeclareBoolOption{dutch}
\DeclareBoolOption{english}
\DeclareBoolOption{briefdrager}
\DeclareStringOption[dutch]{lang} 
\DeclareStringOption[fwn]{faculty} 
\DeclareStringOption{author} 
\setkeys{leil}{dutch}
\ProcessKeyvalOptions{leil}
%    \end{macrocode}
%
%  Set the |leil@lang| variable to english if the option |english| is given.  
%    \begin{macrocode}
\ifthenelse{\boolean{leil@english}}{\renewcommand*{\leil@lang}{english}}{}
%    \end{macrocode}
%
%  The user-specified options go through some rudimentary error checking. The 
%  language option is processed such that specifying options other than Dutch or 
%  English defaults to Dutch. The faculty option is switched back to |fwn| if 
%  an unknown value is specified. 
% 
%    \begin{macrocode}
\ifthenelse{\equal{\leil@lang}{dutch}\OR\equal{\leil@lang}{english}}{\relax}%
    {\PackageWarningNoLine{leiletter}{Only languages supported are Dutch and English. 
     Defaulting to Dutch now, you specified \leil@lang}}	
\ifthenelse{\equal{\leil@faculty}{fwn}\OR\equal{\leil@faculty}{fgw}\OR
            \equal{\leil@faculty}{fsw}\OR\equal{\leil@faculty}{gga}\OR
            \equal{\leil@faculty}{med}\OR\equal{\leil@faculty}{law}\OR
            \equal{\leil@faculty}{arch}}{\relax}%
    {\PackageWarningNoLine{leiletter}{You specified illegal input for the faculty. 
     Switching back to fwn, you specified \leil@faculty}
     \renewcommand*{\leil@faculty}{fwn}}	
%    \end{macrocode}
%
%  This concludes the specification of package options. 
%
% \subsection{Parent Class and Packages}
%
% The |LEIletter| class builds upon the KOMA-script letter class |scrlttr2|, 
% that is loaded here. The |scrlayer-scrpage| package is also part of KOMA-script
% and allows for placement layers of blocks of material (text, images) on pages. 
% These layers offer more flexibility than the |scrlttr2| package and allow for 
% much cleaner programming. 
% 
%    \begin{macrocode}
\LoadClass{scrlttr2}
\KOMAoptions{
  fontsize=11pt,
  paper=a4,
  usegeometry=true,
  parskip=full,
  pagenumber=false,
  enlargefirstpage=on,    % More space on first page
  fromrule=off,           % No Rule after sender name in letter head
  addrfield=topaligned,   % Adress field for envelope with window
  backaddress=off,         % Sender address in this window (use plain to remove rule)
  refline=nodate,
  foldmarks=on,           % Print foldmarks
}
\RequirePackage{scrlayer-scrpage}
\pagestyle{scrheadings}
%    \end{macrocode}
%
%  The |array| package is required to typeset the reference line (letter number, date, etc)
%  in a tabular environment (well, mostly to tweak the spacing between rows). Babel is 
%  loaded here (it is also loaded by scrlttr2) with the correct language switch. Hyperref 
%  is included for typesetting of links without too much color. Note that this can be 
%  overwritten by the user with an alternative |\hypersetup| command in the preamble. 
% 
% \changes{v1.2}{2019/11/7}{Added code from parskip.sty to remove parskip around headings
% 							requires etoolbox.sty}
%    \begin{macrocode}
\RequirePackage{array}
\RequirePackage{etoolbox}
\RequirePackage[\leil@lang]{babel}
\RequirePackage{hyperref}
\hypersetup{colorlinks, breaklinks, urlcolor=black, linkcolor=black}
%    \end{macrocode}
%
%  Letters are written left-justified. The package |ragged2e| handles this best. 
% 
%    \begin{macrocode}
\RequirePackage{ragged2e}
\RaggedRight
%    \end{macrocode}
%
%  \begin{macro}{\spacedallcaps}
%  The standard font for Leiden university is Minion. We use the |MinionPro| package 
%  and assume that the full family is installed. The switch |opticals| specifies that
%  slightly different shapes are used at different sizes. The |microtype| package does 
%  small but noticable improvement to the typesetting of text. The |textcase| package 
%  is needed for the specification of the two commands |\spacedallcaps| and 
%  |\spacedlowsmallcaps|, both copied from the |classicthesis| package, that allow for 
%  nicely spaced small caps. 
% 
%    \begin{macrocode}
\RequirePackage{textcase}
\RequirePackage{microtype}
\RequirePackage[fullfamily,opticals]{MinionPro}
\DeclareRobustCommand{\spacedallcaps}[1]{\textssc{\MakeTextUppercase{#1}}}
\DeclareRobustCommand{\spacedlowsmallcaps}[1]{\textssc{\MakeTextLowercase{#1}}}
%    \end{macrocode}
% \end{macro}
%
% The geometry of the page (i.e. the margins) are prescribed in the house style: 
% left margin is 24 mm, bottom margin is 44pt, no footer. The top margin specified
% here is for the pages after the first page - on the first page  the start of the 
% body text is dictated by the location of the reference line. 
%
%    \begin{macrocode}
\RequirePackage[left=4.8cm,right=2.2cm,top=142pt,bottom=44pt,foot=2em]{geometry}
%    \end{macrocode}
% 
%  Document layout: Here we set the location of the address window using 
% |toaddrhpos|, |toaddrvpos| and |toaddrwidth|, kill spacing for back-address 
% (which we do not use), and space for the reference line (that we construct
% differently). We need to set |refvpos| to make sure the text starts at the 
% correct height on the first page. 
%
% (NB: we use here the older |\@setplength| with the at-sign for compatiblity with
% older versions of KOMA-script.) Perhaps, at some point make this something like 
% \begin{verbatim}
%    \ifpackagelater{scrlttr2}{2019/2/1}{
%           \newcommand*{\setplength}{\@setplength}
%    }{}
% \end{verbatim}
%
%    \begin{macrocode}
\@setplength{toaddrhpos}{24mm}
\@setplength{toaddrvpos}{146pt}
\@setplength{toaddrwidth}{72mm}
\@setplength{toaddrheight}{77pt}
\@setplength{backaddrheight}{0pt}
\@setplength{subjectaftervskip}{0pt}
\@setplength{subjectbeforevskip}{0pt}
\@setplength{refaftervskip}{0pt}
\@setplength{sigbeforevskip}{3.0\baselineskip}
\@setplength{refvpos}{350pt}
\setlength\parindent{0pt}
%    \end{macrocode}
%
% 
%  Formatting of the signature left justified, and use a colon for the enclosed
%  documents. 
%
%    \begin{macrocode}
\renewcommand*{\raggedsignature}{\raggedright}
\setkomavar{enclseparator}{: }
%    \end{macrocode}
%
%
%  Line spacing: making text register onto a grid is a nightmare in \LaTeX. The following
%  is mostly taken from the |grid| package. which is to incompatible with KOMA-script
%  to just use as is. We begin with some preliminaries, defining the grid to be 14 points
%  and setting the default font size to 11 pt. 
% 
%    \begin{macrocode}
\def\leil@fontsize{11pt}
\def\leil@baseline{14pt}
%    \end{macrocode}
%
%  Next, we redefine the font sizes |normalsize| and |small| to have 14 pt leading and
%  we set all the ``rubber'' lengths of latex to fixed multiples of 14 pt. We also set
% |\parskip| to a full but single line. 
% 
%    \begin{macrocode}
\renewcommand\normalsize{%
   \baselineskip=\leil@baseline%
   \@setfontsize\normalsize{\leil@fontsize}{\leil@baseline}%
   \lineskip=0pt
   \lineskiplimit=-\leil@fontsize%
   \abovedisplayskip \baselineskip%
   \abovedisplayshortskip .5\baselineskip%
   \belowdisplayskip \abovedisplayskip
   \belowdisplayshortskip \abovedisplayshortskip
   \let\@listi\@listI}
\renewcommand\small{%
   \baselineskip=\leil@baseline%
   \@setfontsize\normalsize{10pt}{\leil@baseline}%
   \lineskip=0pt
   \lineskiplimit=-\leil@fontsize%
   \abovedisplayskip \baselineskip%
   \abovedisplayshortskip .5\baselineskip%
   \belowdisplayskip \abovedisplayskip
   \belowdisplayshortskip \abovedisplayshortskip
   \let\@listi\@listI}
\normalsize
\parskip \leil@baseline
%    \end{macrocode}
%
%  Still working on sticking to the grid: the following code creates an enviroment
%  |gridenv|, such that anything between |\begin{gridenv}| and |\end{gridenv}| takes
%  up an integer multiple of |\baseline|, such that the text below registers again. 
%  For details, consult the |grid| package on CTAN.

%  is sticking to the 14 pt grid. The code is lifted from |sections.lco|

% \subsection{University logo}
% 
%  The house style stipulates location of the logo (35pt from the top edge of the
%  paper, 24 mm from the left edge of the paper). Size is not precisely prescribed. 
%  The logo as available on the house style website has wide boundaries, so a little
%  readjustment of the location is needed using |addvoffset| and |addhoffset|. 
%  Size is not precisely prescribed, so we put the logo at the upper-left part of the
%  layer. For documentation of the |\DeclareNewLayer| and |\AddLayerstoPageStyle| 
%  commands, consult the |scrlayer=scrpage| documentation.

% \section{User Specific Information}
% Information that is used for every letter, typically the name and details
% of the sender of the letter, can be supplied in file |medewerker.lco|, which 
% is loaded using the option |author=medewerker| at the \cs{documentclass} line. 
% The following is a template for filling the file. Note that all these can also be 
% specified in the preable or overwritten using \cs{renewcommand} calls.
% \begin{macro}{\leiltitle}
% The title should be written without spaces between titles as per LEI style guide. 
% The titles, first name and last name are used to construct the signature under the letter.
%    \begin{macrocode} 
\leiltitle{prof.\,dr.} 
%    \end{macrocode}
% \end{macro}
% 
% 
% \begin{macro}{\leilfirstname}
% The fist name should be written with capitals and non-breaking space |~| between 
% name and initials. No spaces between the initials if there are more than one. 
%    \begin{macrocode} 
\leilfirstname{Maria~E.}
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leiltitle}
% The last name should be written without capitalization of de/van/der/etc. Use non-breaking
% spaces and/or non-breaking hyphens for multi-part names, as appropriate. 
%    \begin{macrocode} 
\leillastname{de~Werker} 
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leilemail}
% Specify the email address (currently not used but maybe in later versions.)
%    \begin{macrocode} 
\leilemail{m.e.dewerker@leidenuniv.nl} 
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leildirectphone}
% Specify the telephone number that is to appear in the reference letter (direct-dial number
% or Doorkiesnr. in Dutch). Use a full space between (071) and a half-space after the first 
% three digits, usually 527. Do not enter only the last four digits. 
%    \begin{macrocode} 
\leildirectphone{(071)~527\,0000} 
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leilcontact}
% Specify the name of the assistant of the sender or the name of the secretariat that 
% belongs to the direct-dial phone number. 
%    \begin{macrocode} 
\leilcontact{Secretariaat Belangrijk} 
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leiljobtitle}
% Specify, if so desired, the job title, which is typeset on a separate line below the 
% name in the signature. The jobtitle may be different in English and Dutch, so it may
% be wise to specify it bilingually. 
%    \begin{macrocode} 
\iflanguage{english}{
	\leiljobtitle{Professor of Relevant Subject}
}{
	\leiljobtitle{Professor in de Belangrijke Wetenschap}
}
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leilbuilding}
% Specify the location of the sender. This is not idential for all employees per 
% faculty, so it must be supplied to go above the contact details of the faculty. 
%    \begin{macrocode} 
\iflanguage{english}{
	\leilbuilding{Leyden Building}
}{
	\leilbuilding{Leids Gebouw}
}
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leilunit}
% Specify the institute or depart (sub-unit of the faculty) of the sender. This is 
% printed under name of the faculty at the top-right of every page. 
%    \begin{macrocode} 
\iflanguage{english}{
	\leilunit{Institute of Relevance}

% \section{Minimal Example}
% The following is a minimal example for a letter, using the |lipsum| package to 
% generate dummy text, that shows how to use premable commands per letter. 
%
% The first line contains the call to the |LEIletter| document class, and specifies
% options |dutch| (default) or |english|, specifies the author details to be loaded 
% from |medewerker.lco| and the faculty that the sender belongs to.

\documentclass[author=medewerker,faculty=fwn]{LEIletter}
%    \end{macrocode}
%
%
% \begin{macro}{\leilnumber}
%   This macro sets the |\leil@number| tag that  will be used to specify the
%   number or unique identifier of the letter (e.g. for archiving and referencing
%   purposes). 
%    \begin{macrocode} 
\leilnumber{MEdW/123} 
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leilyourref}
%   This macro sets the |\leil@yourref| tag that  will be used to specify the
%   date of the correspondence that the letter relates to. 
%    \begin{macrocode} 
\leilyourref{12 april 2019} 
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\leilsubject}
%   This macro sets the |\leil@subject| tag that later will be used in the
%   reference line for the subject of the letter. 
%    \begin{macrocode}
