for the distinction between base font and font package and % for suggesting ``expected functionality'' packages on sectioning, % long tables, headers, and double spacing, and links to FAQ and CTAN. % % Lars Madsen, Will Robertson, Robin Fairbairns and others for asking % for the center environment in tables and figures to be replaced with % the \centering command (I still disagree, but WTF :-) % % Tsy for spotting a typo in the table code sample. % % Rob Felty and Domink Wass for pointing me at Winston Chang's % excellent LaTeX Cheat Sheet summary. % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % This is laid out for A5 pages with margins optimised for my HP K7100 % so that I can impose two pages per A4 sheet and print double-sided. % It has not been tested at letterpaper size (and may not fit). % \documentclass[a5paper]{article} % % The 12mm margin is needed because my printer cannot print the % bottom 12mm of a sheet, so if I print 2-up A5 pages on an A4 % sheet, I need to allow for the fact that one edge of two of the % pages must have a 12mm margin -- so it's preferable to make it % the same all round. % %

What's \LaTeX?} \LaTeX\ is a document preparation system for the \TeX\ typesetting program. It enables you to produce publication-quality output with great accuracy and consistency. \LaTeX\ works on any computer and produces industry-standard PDF or PS documents. It is available both in free (open-source) and commercial implementations. \LaTeX\ can be used for any kind of document, but it is especially suited to those with a complex structure, repetitive formatting, or notations like mathematics\footnote{For reasons of space this guide does not cover details of mathematics typesetting.}; or where technical stability, dimensional accuracy, or a persistent and non-proprietary file format are needed. Install the free software from \url{www.tug.org/texlive/} or buy a commercially-supported version from one of the vendors (see back page). \subsection{Creating and typesetting your document} \begin{enumerate}[noitemsep]\setlength{\fboxsep}{1pt} \item Create your document using any suitable plain-text editor with \LaTeX\ controls, eg \textit{\TeX shop} (Mac), \textit{\TeX nicCenter} (Win), \textit{Kile} (Linux), \textit{Emacs} (all), even \textit{vi}\thinspace! \item Save the file with a name ending in \verb+.tex+ (\emph{never} use spaces in filenames!); \item Use the toolbar buttons or menu items in your editor to typeset and display the document (you need \textit{Acrobat Reader} or similar to display the PDF output);\label{typeset} \item Make any changes needed in your original document and repeat step \ref{typeset}. \end{enumerate} \subsection{Syntax (how to type \LaTeX\ commands --- these are the rules)} \begin{itemize}[noitemsep] \item \textbf{All \LaTeX\ commands begin with a backslash}.\\ \example \verb+\tableofcontents+\endexample \item \textbf{If a command needs text to work with (an `argument'), it goes in curly braces}.\\ \example \verb+\title{Irisches Tagebuch}\author{Heinrich Böll}+\endexample \item \textbf{If options are used, they go in square brackets first, before the curly braces}.\\ \example \verb+\documentclass[a4paper,11pt]{book}+\endexample \item \textbf{Spaces after commands \emph{without} braces get suppressed}.\\ \example \verb+Copyright \copyright␣+\texttt{\number\year} \gives{Copyright \raisebox{1pt}\copyright \number\year}~\nobox\\ To prevent this, put empty curly braces after the command.\\ \example \verb+Copyright \copyright{}␣+\texttt{\number\year} \gives{Copyright \raisebox{1pt}\copyright{} \number\year}~\yesbox \item \textbf{Curly braces are also used to restrict the scope of effects inside them}.\\ \example \verb+Some {\tiny little} word+ \gives{Some {\tiny little} word} \end{itemize} \vfill \begin{note} This guide shows only a tiny fraction of \LaTeX's power. For more information, visit the \TeX\ Users Group site (\url{www.tug.org}). For help, see the FAQ (\url{www.tex.ac.uk/faq}) and the Usenet newsgroup \url{comp.text.tex}.

These three lines are \emph{compulsory}: your document will not work without them: \begin{Verbatim}[frame=single,fontsize=\small,commandchars=!<>] \documentclass{article} !comment your Preamble goes here (extra setups, if any) \begin{document} !comment your document text goes here \end{document} \end{Verbatim} \begin{itemize}[noitemsep] \item The document class name must be one of the standard \verb+book+, \verb+article+, or \verb+report+, or one of the many extras preinstalled or downloadable (eg \verb+thesis+, \verb+memoir+, etc). \item There are paper size options \verb+a4paper+ (210\thinspace mm$\times$297\thinspace mm) and \verb+letterpaper+ (8\nicefrac12$''\times$11$''$) and others (eg \verb+a5paper+). \item There are body type size options \verb+10pt+ (the default), \verb+11pt+, and \verb+12pt+. \end{itemize} New material introduced in each example is shown below in {\ttfamily\added blue}; previous material in black. \subsubsection{Front matter} The \textbf{Preamble} is where you specify any extra \textbf{packages} (\LaTeX\ plugins) such as typefaces or special formatting requirements, and where you put any changes to standard features. \begin{Verbatim}[frame=single,fontsize=\small,commandchars=!<>] \documentclass[a4paper,11pt]{book} !added\usepackage{charter,graphicx}!revert !added\setlength{\parindent}{1em}!revert \begin{document} !added\title!comment{your document title!revert} !added\author!comment{your name!revert} !added\date!comment{date of publication!revert} !added\maketitle !added\begin{abstract} !comment the paragraphs of your abstract go here !added\end{abstract} !added\tableofcontents !comment the text of your document goes here \end{document} \end{Verbatim} In a typical document, the title, author, date, abstract (summary), and table of contents (optional) all go at the start, followed by your text. Leave a blank line between paragraphs as you type. To \LaTeX, this means `start a new paragraph', \emph{not} `leave a blank line'. You can control spacing and indentation by setting \verb+\parskip+ and \verb+\parindent+ with the \verb+\setlength+ command as in the previous example, or with the \textsf{parskip} package. \subsubsection{Sections and cross-references} Sections get numbered automatically in bold type, and get included in the Table of Contents (if any). Numbering can be turned off selectively. Section heading layout can be modified with the \textsf{sectsty}, \mbox{\textsf{titlesec}}, and other packages. Use the \textsf{babel} package for other languages. \begin{Verbatim}[frame=single,fontsize=\small,commandchars=!<>] !comment (Preamble, titling, and abstract as above) !added\setcounter{secnumdepth}{3} \tableofcontents !added\chapter!comment{heading of a chapter!revert} !comment text for the chapter goes here !added...as shown in section \ref{blah}. !added\section!comment{heading of a section!revert} !added\label{blah} !comment make up name for the label !comment text for the section goes here !added\chapter!comment{heading of a new chapter!revert} !comment text for the new chapter goes here \end{document} \end{Verbatim} For cross-references, use \verb+\label{...}+ to label the target and \verb+\ref{...}+ and/or \verb+\pageref{...}+ to refer to it. Make up the label values: \LaTeX\ will use them to work out the right numbers to print.\\ \example{...\ttfamily section \verb+\ref{blah}+ on p.\\ \verb+\pageref{blah}+.}\gives{...section 3 on p.9}. \subsubsection{Typefaces} \LaTeX's default typeface is Computer Modern. There is a selection of other typeface packages (use them in your Preamble): {\footnotesize\tabcolsep4pt \def\ff#1{\fontfamily{#1}\selectfont} \begin{tabular}{@{}l@{\hspace{6pt}}>{\ttfamily}l|l@{\hspace{6pt}}>{\ttfamily}l@{}} \ff{ptm}Times&mathptmx&\ff{pcr}Courier&courier\\ \ff{ppl}Palatino&mathpazo&\ff{pag}\scriptsize Avant Garde&avant\\ \ff{pbk}Bookman&bookman&\ff{phv}Helvetica&helvet\\ \ff{bch}Charter&charter&\ff{pzc}Zapf Chancery&chancery\\ \ff{put}Utopia&utopia&\fontencoding{OT1}\ff{pnr}Pandora&pandora\\ \ff{pnc}Century&newcent&\fontencoding{U}\ff{yfrak}Fraktur&oldgerm\\ \end{tabular} } See each package's documentation for details. \columnbreak\parskip5pt Dozens of others are available, including mathematical and decorative fonts. To switch to a sans-serif type family (eg Helvetica, Avant Garde), use \verb+\sffamily+ in your text. To change font for a word or phrase, use these commands (they can be nested---see below): {\small \begin{tabular}{l@{\enspace}>{\ttfamily\char'134 text}l<{\char'173 Hello\char'175}@{}>{\ \gives\bgroup}l<{\ Hello\egroup}} Italics&it&\itshape\\ Boldface&bf&\bfseries\\ Smallcaps&sc&\scshape\\ Sans-serif&sf&\sffamily~~\\ Monospace&tt&\ttfamily\\ \end{tabular}} \example \verb+\textit{\textbf{\textsf+\linebreak \verb+{bold italic sans}}}+ \gives{\textit{\textbf{\textsf{bold italic sans}}}} Font sizing is automatic for titles, headings, and footnotes. There are some named step-size commands (in points, relative to the base size): {\small \begin{tabular}{>{\ttfamily\char'134}lrrr} normalsize&10&11&12\\\hline\vrule height1.1em width0pt tiny&5&6&7\\ scriptsize&6&7&8\\ footnotesize&7&8&9\\ small&9&10&11\\ large&11&12&14\\ Large&12&14&17\rlap*\\ LARGE&14&17\rlap*&20\rlap*\\ huge&17\rlap*&20\rlap*&24\rlap*\\ Huge&20\rlap*&24\rlap*&28\rlap*\\ \end{tabular} \quad \rotatebox[origin=c]{90}{\scriptsize* sizes rounded here to save space} } You can specify an exact size with the \textsf{fix-cm} package and the command:\\ \verb+ \fontsize{+\texttt{\textit{pp}}\verb+}{+\texttt{\textit{bb}}\verb+}\selectfont+\\ for any point-size (\textit{pp}) on any baseline (\textit{bb}). Enclose the command \emph{and} its applicable text in curly braces to prevent it affecting the rest of the document. For double or 1\nicefrac12 line-spacing (eg in theses) use the \textsf{setspace} package. You can also use RGB, CMYK, HTML, and many other \linebreak colourspaces with the \\\textsf{xcolor} package and the\hfil \smash{\raisebox{0ex}{\fontfamily{ppl}\selectfont\Huge\quad \textcolor[HTML]{2F50AD}{G}% \textcolor[HTML]{B32F17}{o}% \textcolor[HTML]{F3C20B}{o}% \textcolor[HTML]{2F50AD}{g}% \textcolor[HTML]{48C847}{l}% \textcolor[HTML]{B32F17}{e}}}% % web colour for l was 567122 % web colour for o2 was CAB340 \\\verb+\color{+\texttt{\textit{name}}\verb+}+ command. For verbatim text, use the \textsf{listings} or \textsf{fancyvrb} packages, or the \verb+\verb+ command. \subsubsection{Lists} There are three basic kinds: \textbf{itemized} lists (bulleted); \textbf{enumerated} lists (numbered or lettered); and \textbf{descriptive} lists (topic-and-explanation format). Others are avaiable on CTAN[5]. \begingroup\tiny \renewcommand{\labelitemi}{\textbullet} \leftmargini=2em \setlength{\tabcolsep}{3pt} \begin{tabular}{%@{}% p{.24\columnwidth}|% p{.30\columnwidth}|% p{.33\columnwidth}} \begin{verbatim} \begin{itemize} \item 1lb Sugar \item ½pt Cream \item Chocolate \item 2oz Butter \end{itemize} \end{verbatim} & \begin{verbatim} \begin{enumerate} \item Mix together \item Boil to 112°C \item Stir and cool \item Pour into dish \end{enumerate} \end{verbatim} & \begin{verbatim} \begin{description} \item[Fudge] is fun... \item[Broccoli] sucks... \item[Exercise] is good \end{description} \end{verbatim} \\\hline \begin{itemize}[noitemsep] \item 1lb Sugar \item ½pt Cream \item Chocolate \item 2oz Butter \end{itemize} & \begin{enumerate}[noitemsep] \item Mix together \item Boil to 112\textdegree C \item Stir and cool \item Pour into dish \end{enumerate} &\tiny \begin{description}[noitemsep] \item[Fudge] is fun but fattening if made too often. \item[Broccoli] sucks, period. \item[Exercise] is good for you if taken daily and not to extremes. \end{description} \end{tabular} \endgroup You can nest lists inside each other. Use the \textsf{enumitem} package to control list formatting. \subsubsection{Tables and figures} Formal tables and figures will \emph{float} (change position to fit available space). Use \verb+\caption+ and \verb+\label+ to caption and label tables and figures. \begin{Verbatim}[frame=single,fontsize=\footnotesize,commandchars=!<>] !added\begin{table} !added\caption{Mean growth rate and intakes !added of supplement, milk, and water for 4 !added diets.} \label{dietgrowth}\centering !added\begin{tabular}{|l|r|r|r|r|}\hline !added&Growth&Supplement&Milk&Water\\ !added Supplement&rate&intake&intake&intake\\ !added&(g/day)&(g/day)&(ml/kg$^{0.75}$)& !added (ml/kg$^{0.75}$)\\\hline !added Lucerne &145&450&10.5&144\\\hline !added Sesbania&132&476& 9.2&128\\\hline !added Leucaena&128&364& 8.9&121\\\hline !added None & 89& 0& 9.8&108\\\hline !added\end{tabular} !added\end{table} \end{Verbatim} % fake it \begin{center}\fontfamily{cmss}\fontsize56\selectfont \setlength{\tabcolsep}{2pt} \setlength{\arrayrulewidth}{.2pt} \begin{tabular}{@{}|>{\vrule height1em width0pt}l|r|r|r|r|@{}} \multicolumn5l{\textbf{Table 2}: \textit{Mean growth rate and intakes of supplement,}}\\ \multicolumn5l{\textit{milk, and water for four diets} (after Sherington, J, undated)}\\[6pt]\hline \vrule height1.1em width0pt&Growth&Supplement&Milk&Water\\[-1pt] Supplement&rate&intake&intake&intake\\[-1pt] &(g/day)&(g/day)&(ml/kg\textsuperscript{\fontsize34\selectfont 0.75})&(ml/kg\textsuperscript{\fontsize34\selectfont 0.75})\\[3pt]\hline Lucerne &145&450&10.5&144\\\hline Sesbania&132&476& 9.2&128\\\hline Leucaena&128&364& 8.9&121\\\hline None & 89& 0& 9.8&108\\\hline \end{tabular} \end{center} Packages like \textsf{longtable} and \textsf{array} can help with more complex table formats. \colorbox{LightGrey}{\color{black}\begin{minipage}{.965\columnwidth}% \sffamily\scriptsize\bfseries\raggedright For help, see the links on the front and back pages.
