+ The Current Maintainer of this work is Francesco Biccari.
+
+
+
+** Class information ************************************************
+
+ Graphpaper is a new LaTeX document class which allows to print
+ several types of graph papers: bilinear (millimeter paper),
+ semilogarithmic, bilogarithmic, polar, log-polar, Smith charts.
+
+ The documentation is provided in the file graphpaper.pdf.
+
+ The version number of this class is reported at the top of the
+ class file graphpaper.cls and in the pdf manual graphpaper.pdf.
+
+
+
+** Installation instruction *****************************************
+
+ GraphPaper can be installed in 3 different ways:
+
+ 1. The simplest way is by the package manager
+ of your TeX distribution (TeX Live, MiKTeX or MacTeX).
+
+ 2. Instead, if you want to install GraphPaper manually, you have to
+ download the GraphPaper.zip archive from CTAN.
+
+ The archive contains:
+
+ 1. graphpaper.dtx (main file)
+ 2. README (this file)
+
+ You can simply copy graphpaper.dtx into your local work directory
+ and compile it with command "pdflatex.exe graphpaper.dtx",
+ the documentation pdf file and the class file graphpaper.cls
+ will be generated.
+
+ 3. The last possibility is to copy the GraphPaper files
+ (cls and pdf generated as discussed in the previous point and
+ README file) into your texmf tree (or your localtexmf tree) at
+ these locations:
+
+ <texmf>/tex/latex/graphpaper/graphpaper.cls
+ <texmf>/doc/latex/graphpaper/graphpaper.pdf
+ <texmf>/doc/latex/graphpaper/README
+
+ Then, you need to update the file database.

+% \section{How to use graphpaper}
+% \label{sec:howto}
+%
+% \class{Graphpaper} is a \LaTeX\ class and it is loaded as usual:
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}
+\documentclass|\opz{options}|{graphpaper}
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+% It has three class options to specify the paper format:
+% \texttt{a4paper}, \texttt{a3paper}, \texttt{letterpaper}.
+% The paper orientation cannot be changed and it is always set
+% to landscape.
+%
+% \class{Graphpaper} provides the following commands (to be used
+% inside the body of the document) in order to compose graph papers.
+% At the end of the execution of these commands, a new page
+% is always started.
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}
+\bilinear
+
+\semilogx|\marg{decades along x}|
+
+\semilogy|\marg{decades along y}|
+
+\loglog|\opz{0/1}||\marg{decades along x}||\marg{decades along y}|
+
+\polar
+
+\logpolar|\marg{decades along radius}|
+
+\smith
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+% The commands \cs{bilinear}, \cs{semilogx}, and \cs{semilogy} are self
+% explanatory.
+% The optional parameter in the \cs{loglog} command chooses wether the
+% decade length along the abscissa and ordinate axes must have the same
+% dimension. It can assume the value 0 (free dimensions) or 1 (same
+% dimensions), 0 being the default.
+% The commadns \cs{polar}, \cs{logpolar}, \cs{smith} are used to plot
+% polar, logpolar, and Smith chart graph papers. The mandatory argument
+% of \cs{logpolar} specifies the number of decades.
+%
+% There are several commands to change the appearance of the graph papers.
+% They must be inserted before the graph paper command which we want they
+% affect.
+%
+% The following ones are specific to bilinear, semilog and loglog papers
+% only:
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}
+\setxside|\marg{length}|
+
+\setyside|\marg{length}|
+
+\setminimumdistance|\marg{length}|
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+% \cs{setxside} and \cs{setyside} allow to specify the dimensions of the
+% rectangle of the grid. The default values are (260\,mm, 180\,mm) for
+% A4 paper, (250\,mm, 190\,mm) for letter paper, and (380\,mm, 280\,mm)
+% for A3 paper.
+%
+% \cs{setminimumdistance} specifies the minimal optical distance
+% between two lines. Default is 1\,mm. In this way, the number of
+% subdivision is automatically composed.
+%
+% The following commands are instead general settings for all graph
+% papers:
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}
+\setgridcolor|\marg{color}|
+
+\setmajorlinethickness|\marg{length}|
+
+\setmediumlinethickness|\marg{length}|
+
+\setminorlinethickness|\marg{length}|
+
+\customcode|\opz{0/1}\marg{picture environment commands}|
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+% \cs{setgridcolor} sets the color of the grid. The argument must be a
+% color defined or predefined by the color or |xcolor| package. The
+% default color is the typical red-orange color used in many graph papers,
+% Pantone 2011 U corresponding to RGB (250,153,89).
+%
+% \cs{setmajorlinethickness}, \cs{setmediumlinethickness},
+% \cs{setminorlinethickness} can be used to change the thickness of the
+% lines. The default values are 1\,pt, 0.6\,pt, 0.25\,pt, respectively.
+%
+% \cs{customcode} accepts all the commands accepted by the picture
+% environment. This snippet of code is inserted inside the picture
+% environment used to draw the subsequent graph paper.
+% The origin of the coordinate system in the case of rectangular graph
+% papers is the lower left vertex. The \cs{unitlength} is set to 1\,mm.
+% For circular plots (both polar and Smith) the origin is in the center
+% of the circle and the \cs{unitlength} is set to 1/140 of the paper height
+% currently in use.
+%
+% The \cs{customcode} command can be used, for example, to add a logo
+% or to draw on the graph paper.
+% Its optional argument is by default set to 0. If it is set to 1, the
+% content of the \cs{customcode} is erased after its usage in a
+% graphpaper.

+%\section{The implementation}
+% This class file has been already identified by the commands extracted
+% by the |DocStrip| package, during the |.dtx| file compilation.
+% Therefore the commands \cs{NeedsTeXFormat} and \cs{ProvidesClass} are
+% already present in the |.cls| file.
+%
+% \subsection{Loaded packages, class options, and initial settings}
+% The |xkeyvalue| package is used in order to define the class options:
+% \begin{macrocode}
+\RequirePackage{xkeyval}
+% \end{macrocode}
+% Three class options are implemented and they allows only to change the
+% paper format (A4, A3, letter). The orientation of the paper is fixed
+% to landscape.
+%
+% \begin{macrocode}
+\def\GP@paper{1}
+\define@key[GRP]{}{a4paper}[]{\PassOptionsToPackage{a4paper}{geometry}}

+\DeclareOptionX*{\ClassError{graphpaper}{Option '\CurrentOption'%
+ \MessageBreak is not valid}{Remove '\CurrentOption' %
+ from class options}}
+\ProcessOptionsX[GRP]<>
+% \end{macrocode}
+%
+% The class is based on the \class{article} class. The default paper
+% is A4.
+% \begin{macrocode}
+\LoadClass[a4paper,11pt]{article}
+% \end{macrocode}
+%
+% Some packages are loaded. \pack{euclideangeometry} loads \pack{curve2e}
+% which in turns loads \pack{pict2e}; all of them are \env{picture}
+% environment extensions.

+% The ISO-UNI standards prescribe a geometric progression with $\sqrt{2}$
+% ratio, but it is not respected here.
+% It must be keep in mind also that a safe minimum thickness for an offset

+%
+%\subsection{Rectangular graph papers}
+%
+% As we will see below, the commands to compose the bilinear, semilog
+% and loglog graph papers are just proper calls of the low-level command
+% \cs{carta}.
+%
+%\subsubsection{Service macros for rectangular graph papers}
+%
+% First of all, four macros are defined. They are used by the
+% \cs{carta} service command only.
+%
+% Two of them are simply two identical classical |whiledo| commands:
+% the first cycles on the counter \cs{J} while the second one on the
+% counter \cs{K}.
+% They are two because in this way two nested |whiledo| commands can be
+% implemented.
+% These \cs{WhileDo} commands have four parameters:
+% 1. the incremental step of the counter between cycles (default 1);
+% 2. the initial value of the counter;
+% 3. the final value of the counter;
+% 4. the code to execute at each cycle.
+% \begin{macrocode}
+\newcount\J
+\newcount\K
+
+\newcommand\WhileDoOne[4][1]{%
+ \J=#2 \fpdowhile{\J=<#3 }{#4\advance\J by #1\relax}}
+
+\newcommand\WhileDoTwo[4][1]{%
+ \K=#2 \fpdowhile{\K=<#3 }{#4\advance\K by #1\relax}}
+% \end{macrocode}
+%
+%
+% The other two commands are used to draw a periodic set of equidistant
+% lines in log scale.
+% These two commands are practically identical, the only difference is
+% that they act on different axes.
+% These commands have six parameters:
+% 1. number of lines to draw (distance between these lines is the fifth
+% parameter);
+% 2. value at which the first line must be drawn (x-value for vertical
+% lines, y-value for horizontal lines);
+% 3. thickness;
+% 4. tick length;
+% 5. distance between two lines (typically the length of a decade:
+% y-decade for horizontal lines, x-decade for vertical lines);
+% 6. line length (typically the length of the graph paper sides:
+% x-side for horizontal lines and y-side for vertical lines).
+%
+% \begin{macrocode}
+\newcommand\hlines[6]{%
+\multiput(-#4,\fpeval{ln(#2) * #5 / ln(10)})(0,#5){#1}%
+{\linethickness{#3}\line(1,0){\fpeval{#6 + 2*#4}}}%
+}
+
+\newcommand\vlines[6]{%
+\multiput(\fpeval{ln(#2) * #5 / ln(10)},-#4)(#5,0){#1}%
+{\linethickness{#3}\line(0,1){\fpeval{#6 + 2*#4}}}%
+}
+% \end{macrocode}
+%
+%\subsubsection{Command for rectangular graph papers}
+%
+% Here starts the definition of the \cs{carta} command. Its syntax is
+%\begin{ttsyntax}
+%\cs{carta}\opz{0 or1}\marg{no. x decades}\marg{no. of y decades}
+%\end{ttsyntax}
+% If an axis has zero decades, the scale is linear.
+% For example, \cs{carta}\Marg{0}\Marg{0} composes a bilinear graph
+% paper, \cs{carta}\Marg{2}\Marg{0} composes a semilog graph paper with
+% linear y-axis and two decades along x-axis, and so on.
+% Its optional argument can be 0 or 1. If it is set to 0, and both the
+% numbers of decades are greater than zero (which means the resulting
+% graph paper is loglog), then the length of x-axis and y-axis decades
+% are set to be equal.
+%
+% Declaration of the command and its arguments.
+% \begin{macrocode}
+\NewDocumentCommand{\carta}{O{0} m m}{%
+% \end{macrocode}
+%
+% Typographical settings and definition of the main features of the
+% graphpaper. \cs{xlength} and \cs{ylength} represent the lengths,
+% expressed in mm, of the rectangle dimensions. \cs{minimumdistance}
+% is the minimum distance at which two subdivision lines can be drawn.
+% \begin{macrocode}
+\newpage
+\parindent=0pt
+\pagestyle{empty}%
+\color{gridcolor}%
+\setlength{\unitlength}{1mm}%
+\def\ticklength{2}
+\def\minorticklength{1.2}
+\def\minimumdistance{\fpeval{(\mindistanceunit/1mm)}}
+\def\xlength{\fpeval{round(round(\xsideunit/1cm) * 10)}}
+\def\ylength{\fpeval{round(round(\ysideunit/1cm) * 10)}}
+% \end{macrocode}
+%
+% \cs{xlinsq} and \cs{ylinsq} represent the number of big divisions
+% (cm) on horizontal and vertical axes for linear scales, respectively.
+% \begin{macrocode}
+\def\xlinsq{\inteval{\xlength/10}}
+\def\ylinsq{\inteval{\ylength/10}}
+% \end{macrocode}
+%
+% Implementation of the same decade length between x-axis and y-axis
+% for loglog graph paper. This is obtained properly changing the
+% values of \cs{xlength} and \cs{ylength}, making them equal.
+% \begin{macrocode}

+\fi\fi\fi
+% \end{macrocode}
+%
+% Using the values of the paper width and height together with the
+% length of the graph paper rectangle sides, the margins are calculated
+% and passed to the geometry package in order to center the grid with
+% respect to the page.

+%
+% The \class{Graphpaper} class provides commands to draw three different
+% circular graph papers: linear polar chart, log polar chart, Smith chart.
+%
+%\subsubsection{Service macros for Smith charts}
+%
+% Here follows a list of service macros used by circular graph papers.
+%
+% Definition of the counter \cs{I}, used both in polar paper and Smith chart.
+% \begin{macrocode}
+\newcount\I
+% \end{macrocode}
+%
+% |Rbox| composes a tick and a label in a rotated box. It is used to
+% compose the ticks and labels along the external circle of circular
+% graph papers. It accepts three arguments: The first one is
+% optional and represents
+% the angle of rotation (default 0); the second one is optional too,
+% it is inserted by round parentheses, and it represents the position of the
+% box which can be given in cartesian $(x,y)$ or polar coordinates $(\theta:\rho)$
+% (default 0:0); the third one is mandatory and
+% contains the label.
+% \begin{macrocode}
+\NewDocumentCommand\Rbox{O{0} D(){0:0} m}{%

+%
+% |\Xcircle| macro (used only for Smith charts) assumes that the scale
+% factor |\Scala| ($s$) has already been defined and it takes only one
+% mandatory parameter ($x$). It draws a circle with
+% center $(sx/(x+1),0)$ and radius $s/(x+1)$. ($x$ represents the real
+% part (resistance) of the normalised impedance.)

+% \end{macrocode}
+%
+% |\Ycircle| macro (used only for Smith charts) assumes that the scale
+% factor |\Scala| ($s$) has already been defined.
+% It assumes that the circle diameter is 100|\unitlength|s long and it
+% takes only one
+% mandatory parameter ($y$). It draws an arc of a circle with
+% center $(s,s/y)$, starting point at $(s,0)$ (and therefore radius
+% $s/y$) and with an angle calculated in order to have the end point on
+% the external circle. ($y$ represents the imaginary part (reactance)
+% of the normalised impedance.)

+% The following two macros are used to compose the resistance axis
+% below the Smith chart.
+%
+% |CalcRxx| macro (used only for Smith charts) assumes that the scale
+% factor |Scala| ($s$) has already been defined.
+% First, it calculates the reflection coefficient
+% $\Gamma = s \frac{x-1}{x+1}$ from resistance $x$.
+% A tick and a label are inserted for this value of $x$.

+%
+% |GradResist| macro (used only for Smith charts)
+% draws the graduated axis for resistance and executes the |CalcRxx|
+% for several values of resistance in order to compose the ticks and
+% the labels.

+% The syntax is
+%\begin{ttsyntax}

+%\end{ttsyntax}
+% where \meta{diameter} is the dimension (plus some extra space for
+% labels and margins) of the polar chart. Its default value
+% corresponds to the \cs{paperheight} (the minimum dimension of the
+% paper).
+% The mandatory parameter \meta{decades} must be an integer number.
+% Its value corresponds to the number of decades of the radial
+% coordinate for the log polar graph paper.
+% If its value is zero, the chart is linear.
+% The maximum number of allowed decades is set by the macro \cs{NDecMax}:
+% its default value is~2.

+\title{\texttt{principia.sty }\\ A \LaTeXe \space Package for Typesetting Whitehead and Russell's \textit{Principia Mathematica} (Version 1.0)}
+\author{Landon D. C. Elkind \texttt{elkind@ualberta.ca}}
+\date{\today}
+
+\begin{document}
+\maketitle
+\onehalfspacing
+The \texttt{principia} package is designed for typesetting the Peanese notation of \textit{Principia Mathematica}. ``Peanese'' is something of a misnomer: Whitehead and Russell invented much of the notations used in \textit{Principia Mathematica} even while borrowing from many others.
+
+\texttt{principia}'s style has antecedents in Kevin C. Klement's excellent \textit{Tractatus} typesetting, to which we owe the device of adding `d's and `t's to typeset further square dots. The device of beginning all \texttt{principia} commands with `\texttt{$\backslash$pm}' is owed to the \texttt{begriff} package, a style that was mimicked in both the \texttt{frege} package and the \texttt{Grundgesetze} package.
+
+In \textit{Principia Mathematica} some symbols occur with an argument and sometimes that same symbol occurs without an argument. For example, `$\pmsome{x}$' occurs in some formulas, but sometimes `$\pmSome$' occurs in the text when they talk about the symbol itself. \texttt{principia} is designed to accommodate these different occurrences of symbols. When a symbol is to occur without an argument, capitalize the first letter following the `\texttt{$\backslash$pm}' part of the command. E.g. \verb|\pmsome{x}| produces $\pmsome{x}$ and \verb|\pmSome| produces `$\pmSome$'. Note the former command requires an argument and the latter command does not. Not all commands in the \texttt{principia} package admit of such dual use because some symbols in \textit{Principia Mathematica} never occur without an argument or do not take an argument in the usual sense. For example, the propositional connectives do not take an `argument' in the way singular or plural descriptions do.
+
+Version 1.0 of \texttt{principia} is adequate to typeset all notations throughout Volume I of \textit{Principia}. Updates to include all notations throughout Volumes II and III are planned.
+
+\texttt{principia}'s dependencies are \texttt{pifont} (for the eight-pointed asterisk), \texttt{marvosym} (for the `$\pmop$' symbol), and \texttt{graphicx} (for singular descriptions, universal classes, and existential quantifiers). Make sure to load these package by typing \texttt{$\backslash$usepackage\{graphicx\}}, etc.
+
+To load \texttt{principia}, type \texttt{$\backslash$usepackage\{principia\}} in the preamble to the document.
