% \begin{abstract}
% This package provides a mean to easily print a timetable e.g. for a
% semesterplan. The reason for this package to exist is that I wanted to
% reimplement \url{https://github.com/nlschn/semesterplanner/} with
% printing the timetable with |tikz| only (which is more easily to be
% modified) and with the ability of making entries spanning only a fraction
% of the column (for showing simultanious events).
% 
% Documents using this package need to be compiled with
% LuaLaTeX. The package requires |xcolor|, |fontawesome|, |tikz| (and |pgfkeys|).

%
% \section{Usage}
% Load with |\usepackage{semesterplannerlua}|
% \subsection{timetable}
%
% \DescribeEnv{timetable} |\begin{timetable}[opts]...\end{timetable}|\\
% This is the core environment of this package. Within it you can use
% |\lecture|, |\seminar|, |\tutorial|, |\officehour|, |\laboratory|,
% |\fieldstudy| and |\meeting|. All these commands are only defined inside the
% |timetable| environment, and have the same structure. It typesets a timetable
% with the specified entries. If you have a look at the |.sty| file you'll see
% that these macros just take a general macro and set some default values
% before. Thus it is easy to define new ones (keep in mind that you'll need
% |\makeatletter|) to access the general macro.
%
% Writes out a file containing the data from the timetable (your events) to
% be able to have just the |.tex| file containing the timetable, but do
% some scriping on the data (e.g. show the last, current and next events).
% For simplicity the data is stored in lua-syntax (|return|s a table of the
% events). This way we don't need to worry about any string escaping (like
% with csv) and no complicated parsers are needed. Be aware though that a
% simple |events = dofile"path"| has risks since |"path"| might contain lua
% code which is simply executed that way.
%
% |opts| are optional arguments (enclosed with |{}|) separated with |,|:
% \begin{description}
%     \item[|days|] List of the names of the days that should be set as
%     column names. Note that if you specify only 4 names only these 4
%     columns will be printed (with the first day being identified as
%     Monday)
%     \textit{Default: |Mon,Tue,Wend,Thur,Fri|}
%     \item[|dayse|] List of strings used in the code to idenfity the day.
%     This list is kind of a mapping string $\to$ integer.
%     \item[|start time|] Explicit start-time of the timetable given in minutes
%     (|HH*60 + MM|). Can be set as |start time/.evaluated={HH*60 + MM}|.
%     If this is empty, the start time is derived from the given events.
%     \textit{Default: |""|}
%     \item[|end time|] Equivalent to |start-time|
%     \textit{Default: |""|}
%     \item[|width|] Give the width of the timetable. (can be given e.g. as
%     |\textwidth| as this is directly given to tikz).
%     \textit{Default:} |\textwidth|
%     \item[|length|] Give the length of the timetable (measured in |cm|)
%     (has to be a straight number since this is needed in calculation)
%     \textit{Default: 10}
% \end{description}

%
% |opts| are optional arguments (enclosed with |{}|) separated with |,|:
% \begin{description}
%     \item[|title|] Give the name of the lecture
%     \item[|speaker|] Give the name of the lecturer
%     \item[|location|] Give the place of the event (most probably the room or
%     an online plattform, see \ref{icons}). If you want to use
%     |\href{url}{string repr}|, keep in mind that you need to
%     |\unescaped{}| it, since all input to lua has to be text
%     \item[|day|] The weekday on which the event takes place. Has to be
%     one of those you specified in |dayse| (or by default: |M|,|T|,|W|,|Th|,|F|)
%     \item[|time|] The timespan of the event formatted as |HH:MM-HH:MM|
%     (24H clock)
%     \item[|prio|] The priority of the event (see \ref{icons})
%     \item[|scale width|] Specify the width of the entry in fractions
%     of column (use |0.5| to span half the column).
%     \item[|offset|] Shift the entry to the right. Specified in fractions
%     of column.
%     \item[|password|] Original purpose: Only included in the file written
%     out with the timetable data, to be able to make a script which
%     quickly copies url (from |location|) and |password| to the clipboard.
%     \item[|type|] Only included in the file written out with the
%     timetable data as well (Original purpose: To be able to exclude some
%     types)
%     \item[|tikz|] Free customizable event code. See the documentation
%     at the end for keys that can be used here (all keys in |/event|). To
%     simply pass arguments to the tikz-node that is being created for the
%     event use |tikz/.append={your arguments}| (be careful with |text width|,
%     |text height|, |text depth| as these keys are being used for
%     the dimensions of the node as well as with |anchor|)
%     \item[|content|] Is usually set automatically based on the other keys
%     (|title|for instance). This key can override this.
%     \item[|textcolor|] Usually set by the type of macro used
%     \item[|formatter|] internal stub for providing different formatting
%     options. Formatting functions need to be specified in the
%     |-timetable.lua| file
% \end{description}
% The entries |Day| and |Time| are mandatory since they are needed for the
% positioning of the node. All others are merely necessary for the content
% of the node and are therefore nor mandatory.
%
% \subsubsection{Special Notes}
% Note that the |length| argument does specify the length of the timetable
% without taking account of the column headers.
%
% Same goes for the |width| parameter regarding the labels containing the
% time on the right. Since in this case any tex-lenght is allowed, you can
% simply try to subtract the length of the clock label using something like
% |\settowidth{\length}{12:30}| to set a length to the length of a clock
% label and then subtract this from the length you want to specify.
%
% \hangindent=4.5em \hangafter=1 \textbf{Hint:} The content of the environment
% isn't processed by this package. Only the event commands (so to speak
% |\lecture|,|\tutorial|,|\seminar|,|\officehour|,|\fieldstudy|,|\laboratory|,|\meeting|
% are relevant.  All other contents are set immediately before the timetable.
% Therefore, if you wan to add e.g. a |\hspace*{10cm}| to shift the timetable
% to the left, the last line of the env would be the place to do so (there
% musn't be an empty line below since otherwise a new paragraph is started).

% \subsection{Calendar related things}
% Now some environments and commands come which in generally are being used
% to typeset a table with the detailed information, but which also store
% the gathered data internally.\\
% This saved data can be used to output a calendar where the events (from
% the saved data) are highlighted with a mark (already passed days are
% crossed and the current day is highlighted as well).
%
% The different environments described below are similar in general, but
% differ in detail (mostly the list of argument that are passed and printed
% in the table).

% \begin{description}
%   \item[|days|] is a list of
%       strings representing the header names for the day columns in the
%       timetable (adding Sat and Sun (additional entries) will result in
%       two more columns.
%   \item[|start time|] can be used to set a fixed time where the timetable
%       starts (otherwise this is calculated from the entries) to enable
%       this behaviour this key has to be set to |HH*60 + MM| (easy way
%       is by using |start time/.evaluated={HH*60+MM}|)
%   \item[|end time|] equivalent to |start time|
%   \item[|width|] is
%       the horizontal width of the timetable (not including the column
%       headers on the top) this can be a latex length string or
%       |\textwidth| as well.
%   \item[|length|] is the vertical length of the
%       timetable (not including the clock labels on the side)
%       measured in cm (in future versions this may become measured in
%       pts for better interaction with the LaTeX lengths.

%           it so the eventually the string will be evaluated)
%   \item[|time|] is a |HH:MM-HH:MM| string representing start- and
%       end-time of the event. Used in constructing the content as well
%   \item[|day|] is either |M|,|T|,|W|,|Th| or |F| specifying the day on
%       which the event takes place
%   \item[|tikz|] this key allows the user to manually pass options to the
%       node created for this event
%   \item[|scale width|] allows to scale the width of the event to be able
%       to draw overlapping events besides each other. Will usually be a
%       value between |0| and |1|.
%   \item[|offset|] same goal like |scale width| but shifts the event node
%       by the given value to the right. (Given as value between |0| and
%       |1| indicating how many columns the event should be shifted)
%   \item[|textcolor|] foreground color of the content text
