\part*{Usage}

\section{The package}

\subsection{Loading of the package, used packages}

The package \textsf{WriteOnGrid} loads within the preamble :

\begin{PresentationCode}{listing only}
\usepackage{WriteOnGrid}
\end{PresentationCode}

It’s mostly compatible with \textsf{latex}, \textsf{pdflatex}, \textsf{lualatex} or \textsf{xelatex} compilation !

\medskip

It loads the following packages and libraries :

\begin{itemize}
	\item \texttt{xcolor} with options \Cle{table,svgnames} ;
	\item \texttt{tikz} with the librairies \Cle{calc} and \Cle{positionning} ;
	\item \texttt{xstring}, \texttt{xparse} and \texttt{simplekv}.
\end{itemize}

\subsection{The package itself}

The idea is to, thanks to \TikZ, propose commands and environment to work with a grid, and to write on the lines.

\begin{PresentationCode}{listing only}
%environment, with keys to prepare the grid
%commands to write or pass a line

\begin{EnvGrid}[keys]<color>
	\WriteLine[keys]<alignment>{text}
	\PassLine
\end{EnvGrid}
\end{PresentationCode}

\subsection{Overall functioning}

The grid is given by the number of squares (nbCol$\times$nbRow), and after we can adjust with \textit{overtakings} to enlarge the grid onto the margins of the paper (left or right). We can also \textit{adjust} the global margin, to begin the lines differently.

\medskip

For example, a $5\times5$ grid :

\begin{itemize}
	\item with a size 24x5 squares ;
	\item with an overtaking by \textcolor{red}{2 squares at the left} and \textcolor{blue}{3 squares at the right} ;
	\item with a global margin of \textcolor{orange}{1 square} ;
	\item with a \textcolor{ForestGreen}{\textit{border}} to show the \textit{basis} grid.
\end{itemize}

\medskip

\begin{tikzpicture}
	\useasboundingbox (0,0) rectangle ({0.5*24},{-0.5*5}) ;
	\draw[xstep=0.5,ystep=0.5,thin,lightgray!75] ({-0.5*2},0) grid ({0.5*24+0.5*3},{-0.5*5}) ;
	\draw[thick,decorate,decoration={brace,amplitude=8pt,mirror}](0,{-0.5*5-0.25})--({0.5*24},{-0.5*5-0.25}) node[midway,below=8pt,font=\small\sffamily] {24C} ;
	\draw[red,thick,decorate,decoration={brace,amplitude=8pt,mirror}] ({-2*0.5},{-0.5*5-0.25})--({0},{-0.5*5-0.25}) node[midway,below=8pt,font=\small\sffamily] {2C} ;
	\draw[blue,thick,decorate,decoration={brace,amplitude=8pt,mirror}] ({0.5*24},{-0.5*5-0.25})--({0.5*24+3*0.5},{-0.5*5-0.25}) node[midway,below=8pt,font=\small\sffamily] {3C} ;
	\draw[thick,decorate,decoration={brace,amplitude=8pt}] ({0.5*24+3*0.5+0.25},0)--({0.5*24+3*0.5+0.25},{-0.5*5}) node[midway,right=8pt,font=\small\sffamily] {5C} ;
	\draw[very thick,orange,densely dashed] ({0.5*1},0)--({0.5*1},{-0.5*5}) ;
	\draw[ForestGreen,thick] (0,0) rectangle ({0.5*24},{-0.5*5}) ;
\end{tikzpicture}

\vspace{1.25cm}

The \texttt{tikzpicture} is \textit{bounded} by the \textcolor{ForestGreen}{\textit{border}}, in order to specify overtakings or alignment.

\smallskip

Le left-border of the \textcolor{ForestGreen}{\textit{border}} is aligned on the left-margin of the page, so take care of the \texttt{\textbackslash parindent}.

\subsection{Predefined colors}

The package \textsf{WriteOnGrid} proposes "shortcuts" for classic colors !

\begin{PresentationCode}{listing only}
\definecolor{TyrianPurple}{rgb}{0.4,0.01,0.24}
%Colors for Seyes
\def\ColSeyes{Plum!75/LightSteelBlue!50}
%Colors for Ruled
\def\ColRuled{LightSteelBlue!50/TyrianPurple}
\end{PresentationCode}

\pagebreak

\section{Commands, keys and options}

\subsection{The command}

\begin{PresentationCode}{listing only}
%command, with keys to prepare the grid

\DispGrid[keys]<color>
\end{PresentationCode}

The first argument, \textit{optional}, between \texttt{[...]} give the \Cle{keys} :

\begin{itemize}
	\item \Cle{NumSquares} to specify the size of the grid, under \texttt{(nbCol)x(nbRow)} ; \hfill~default : \Cle{17x5}
	\item \Cle{Unit} to specify the scale of the grid ; \hfill~default : \Cle{1}
	\item \Cle{Margin} to specify the global \textcolor{orange}{margin} at the beginning of the lines ; \hfill~default : \Cle{0}
	\item the boolean \Cle{DispBar} to display or not the bar ; \hfill~défaut : \Cle{true}
	\item \Cle{Enlarge} to specify the squares-overtakings, globally with \texttt{\textcolor{red}{L}\textcolor{blue}{R}} or side by side with \texttt{\textcolor{red}{L}/\textcolor{blue}{R}} ;\hfill~default : \Cle{0}
	\item the boolean \Cle{Border} to display the basis border of the grid ;\hfill~default : \Cle{false}
	\item the key\Cle{Grille}, from \Cle{5x5/Seyes/Ruled}, to specify the grid's type.\hfill~défaut : \Cle{5x5}
\end{itemize}

The second argument, \textit{optional}, between \texttt{<...>} is the color(s) of the grid :

\begin{itemize}
	\item by \Cle{Color} (\Cle{lightgray!50} by default) for $5\times5$  ;
	\item by \Cle{ColorA/ColorB} (\Cle{lightgray!50/lightgray!25} by default) for Seyes or Ruled.
\end{itemize}

\medskip

\begin{PresentationCode}{listing only}

\subsection{The environment}

\begin{PresentationCode}{listing only}
%environment, with keys to prepare the grid

\begin{EnvGrid}[keys]<color>
	...
\end{EnvGrid}
\end{PresentationCode}

The first argument, \textit{optional}, between \texttt{[...]} give the \Cle{keys} :

\begin{itemize}
	\item \Cle{NumSquares} to specify the size of the grid, under \texttt{(nbCol)x(nbRow)} ; \hfill~default : \Cle{17x5}
	\item \Cle{Unit} to specify the scale of the grid ; \hfill~default : \Cle{1}
	\item \Cle{Margin} to specify the global \textcolor{orange}{margin} at the beginning of the lines ; \hfill~default : \Cle{0}
	\item the boolean \Cle{DispBar} to display or not the bar ; \hfill~défaut : \Cle{true}
	\item \Cle{Enlarge} to specify the squares-overtakings, globally with \texttt{\textcolor{red}{L}\textcolor{blue}{R}} or side by side with \texttt{\textcolor{red}{L}/\textcolor{blue}{R}} ;\hfill~default : \Cle{0}
	\item the boolean \Cle{Border} to display the basis border of the grid ;\hfill~default : \Cle{false}
	\item the key\Cle{Grille}, from \Cle{5x5/Seyes/Ruled}, to specify the grid's type.\hfill~défaut : \Cle{5x5}
\end{itemize}

The second argument, \textit{optional}, between \texttt{<...>} is the color(s) of the grid :

\begin{itemize}
	\item by \Cle{Color} (\Cle{lightgray!50} by default) for $5\times5$  ;
	\item by \Cle{ColorA/ColorB} (\Cle{lightgray!50/lightgray!25} by default) for Seyes or Ruled.
\end{itemize}

	\end{EnvGrid}
\end{center}

\pagebreak

\subsection{Write on the lines}

The idea is to write on the created grid (environment !). In order to write \textit{right} on the lines, we can :

\begin{itemize}
	\item give the lines one by one ;
	\item avoid using multilines paragraps, items ;
	\item pass a line.
\end{itemize}

\begin{PresentationCode}{listing only}
...
	%to write the lines, one by one
	\WriteLine[keys]<alignment>{text}
	%to pass the ligne
	\PassLine
...
\end{PresentationCode}

The fisrt argument, \textit{optional}, between \texttt{[...]} give the \Cle{keys} :

\begin{itemize}
	\item \Cle{OffsetH}, in squares, to shift the text from the \textcolor{orange}{margin} ; \hfill~default : \Cle{0}
	\item \Cle{OffsetV} to shift vertically the line ; \hfill~default : \Cle{0pt}
	\item \Cle{Scale} to specify the scale of the given text.\hfill~default : \Cle{1}
\end{itemize}

the second argument, \textit{optional}, between \texttt{<...>} is the horizontal alignment (\Cle{left/center/right}) of the text in the basis \textcolor{ForestGreen}{\textit{border}}, \Cle{left} by default.

\medskip

Le third argument, \textit{mandatory} and between \texttt{\{...\}} is the text, eventually with options.

\begin{PresentationCode}{listing only}
\begin{EnvGrid}[NumSquares=36x8]
	\WriteLine[Scale=1.5]{my text on ligne 1\ldots}
	\WriteLine[Scale=1.5]<center>{\ttfamily my tetetype text centered on line 2\ldots}
	\WriteLine[Scale=1.5]<right>{right-align text on line 3\ldots}
	\WriteLine[Scale=1.5,OffsetH=0.1]{\textcolor{red}{red text, 1mm-shifted\ldots}}
	\PassLine
	\WriteLine[Scale=0.5]{\sffamily sans serif text, reduced by 50\,\%, on line 6\ldots}
	\WriteLine[Scale=1.5,OffsetH=3]{\cursive 3 squares-shifted text\ldots}
\end{EnvGrid}
\end{PresentationCode}

\begin{EnvGrid}[NumSquares=36x8]
	\WriteLine[Scale=1.5]{my text on ligne 1\ldots}
	\WriteLine[Scale=1.5]<center>{\ttfamily my tetetype text centered on line 2\ldots}
	\WriteLine[Scale=1.5]<right>{right-align text on line 3\ldots}
	\WriteLine[Scale=1.5,OffsetH=0.1]{\textcolor{red}{red text, 1mm-shifted\ldots}}
	\PassLine
	\WriteLine[Scale=0.5]{\sffamily sans serif text, reduced by 50\,\%, on line 6\ldots}
	\WriteLine[Scale=1.5,OffsetH=3]{\cursive 3 squares-shifted text\ldots}
\end{EnvGrid}

\begin{PresentationCode}{listing only}
\begin{EnvGrid}[NumSquares=16x4,Margin=2,Grid=Ruled]<\ColRuled>
	\WriteLine[Scale=1.5]{\textcolor{red}{red text on line 1\ldots}}
	\WriteLine[Scale=1.15,OffsetH=1]{$(1+x)^2=1+2x+x^2$ on line 2, with 1-square offset\ldots}
	\WriteLine[OffsetH=-1]{\textcolor{blue}{blue text, back to left, on line 3\ldots}}
\end{EnvGrid}

\end{PresentationCode}
\begin{EnvGrid}[NumSquares=16x4,Margin=2,Grid=Ruled]<\ColRuled>
	\WriteLine[Scale=1.5]{\textcolor{red}{red text on line 1\ldots}}
	\WriteLine[Scale=1.15,OffsetH=1]{$(1+x)^2=1+2x+x^2$ on line 2, with 1-square offset\ldots}
	\WriteLine[OffsetH=-1]{\textcolor{blue}{blue text, back to left, on line 3\ldots}}
\end{EnvGrid}

\part*{Additional informations}

\section{Introduction}

There's few other possibilities with the package\textsf{WorkOnGrid}, but for the moment only with \textit{french} keys, so there's no specific documentation for these commands.

\smallskip

To sum up, they create full paper grid (by preference for \texttt{\textbf{a4paper}}), with the ability to write paragraph.

\section{Example}
