\subhead{What is \TeX?}
|
|
|
|
\TeX\ (pronounced ``teck'') is a computerized typesetting system developed by
|
|
Donald Knuth and others at Stanford University. It is used to create
|
|
high-quality documents, particularly those containing mathematics.
|
|
The name \TeX\ is an uppercase form of the Greek letters $\tau\epsilon\chi$,
|
|
the first three letters of a Greek word meaning {\sl art} as well as
|
|
{\sl technology}.
|
|
The lowering of the ``E'' is a reminder that \TeX\ is about typesetting,
|
|
which can be thought of as the next stage beyond word processing.
|
|
On devices where such lowering is difficult or impossible you may see \TeX\
|
|
written as {\tt TeX}.
|
|
|
|
% the above blank line ends the first paragraph
|
|
|
|
Most word processors allow you to
|
|
create and modify a document interactively --- what
|
|
you see on the screen is usually what your output will look like.
|
|
\TeX\ does {\it not} work in this way.
|
|
Like other typesetting systems (such as SCRIBE and
|
|
{\sl troff\/}), \TeX\ is known as a ``document compiler''. Using your
|
|
favourite text editor you need to create a file containing the
|
|
text of your manuscript along with the \TeX\ typesetting commands.
|
|
\TeX\ gives you the ability to produce printed matter with a quality
|
|
matching that found in books, depending on the output device.
|
|
Adelaide University has an {\sm imagen} laser printer
|
|
with a resolution of 240 dots per inch.
|
|
This publication shows both the capabilities of \TeX\ and
|
|
the output quality of the laser printer.
|
|
|
|
\subhead{Fonts}
|
|
|
|
One of the more obvious advantages of \TeX\ is the large range of fonts from
|
|
which you can choose. A font is a collection of characters each having a
|
|
similar size and style. Some of the fonts currently available include:
|
|
$$ % enter display math mode just to get space above and below \line
|
|
\line
|
|
{\hfil % infinitely stretchable glue
|
|
\rm roman\hfil \sl slanted\hfil \it italic\hfil \bf boldface\hfil
|
|
\tt typewriter\hfil \ss sans serif\hfil \sm small caps\hfil
|
|
} % take care to ensure each { has a matching }
|
|
$$
|
|
Many of these also come in a variety of sizes:
|
|
$$
|
|
\centerline{{\bigrm from the very big},~ % extra space after comma
|
|
{\ninerm to the very small},~
|
|
{\fiverm to the ridiculous}.}
|
|
$$
|
|
Apart from a large selection of mathematical symbols,
|
|
many special characters and accents are available:
|
|
$$
|
|
\vbox
|
|
{\tabskip 10pt plus 1fil % glue before and after all columns
|
|
\halign to\hsize
|
|
{& \hfil#\hfil\cr % specify a variable number of centred columns
|
|
\copyright& \it\$& \S& \P& \dag& \ddag&
|
|
$\circ$& $\bigcirc$& % some symbols must be accessed from math mode
|
|
$\leftarrow$& $\rightarrow$& $\triangle$& $\clubsuit$&
|
|
\`a& \'e& \c c& \^o& \"u\cr
|
|
}
|
|
}
|
|
$$
|
|
\TeX\ does a few subtle things automatically.
|
|
Certain sequences of characters in your text will
|
|
be replaced by {\sl ligatures} in the printed output (consider the ``{\tt ffi}''
|
|
in ``difficult''), while other pairs of characters need to be {\sl kerned}
|
|
(e.g., the ``o'' and ``x'' in ``box'' look better if they are moved closer
|
|
together). The range and quality of fonts available will continue to improve.
|
|
|
|
\subhead{Mathematics}
|
|
|
|
A major design goal of \TeX\ was to simplify the task of typesetting
|
|
mathematics --- and to do it properly. Mathematicians will be pleasantly
|
|
surprised at the ease with which formulae and expressions can be created;
|
|
from simple in-line equations
|
|
such as $e^{i\pi}=-1$ and $f_{n+2}=f_{n+1}+f_n$, to more extravagant displays:
|
|
$$
|
|
\sum_{k\ge1} \sqrt{x_k-\ln k}\quad\ne\quad
|
|
\int_{0}^\infty {e^{-x^3}+\sqrt{x} \over \left(123-x\right)^3} \,dx
|
|
$$
|
|
\TeX\ looks after most of the nitty gritty details, such as spacing things
|
|
correctly and choosing the right sizes for superscripts, parentheses,
|
|
square root signs etc. (The discoverer of the above relation wishes to
|
|
remain anonymous.)
|
|
|
|
\subhead{Alignment}
|
|
|
|
The preparation of tabular material such as in lists and matrices can be a
|
|
tedious job for a person armed only with a typewriter and a bottle of
|
|
correction fluid. With a little help from \TeX, computers can make it so
|
|
much easier:
|
|
$$
|
|
\vcenter % a vertically centred \vbox
|
|
{\tabskip 0pt % no space before column 1
|
|
\halign to 3.5in % width of table
|
|
{\strut#& % col 1 is a strut
|
|
\vrule#\tabskip .5em plus2em& % col 2 is a vrule; also set col spacing

\subhead{Other features}
|
|
|
|
Space does not permit examples of all the things \TeX\ can do. Here are some
|
|
more features you might like to know about:
|
|
|
|
\item{$\bullet$}
|
|
Multi-column output can be generated.
|
|
|
|
{\parskip=0pt % temporarily turn off the skipping between paragraphs
|
|
\item{$\bullet$}
|
|
\TeX\ has a very sophisticated paragraph building algorithm and rarely needs
|
|
to resort to hyphenation. Paragraphs can be indented and shaped in many
|
|
different ways.
|
|
|
|
\item{$\bullet$}
|
|
Automatic insertion of footnotes,\footnote{\dag}{\ninerm Here is
|
|
a footnote.} running heads, page numbers etc.
|
|
|
|
\item{$\bullet$}
|
|
\TeX\ makes provision for generating a table of contents, a bibliography, even
|
|
an index. Automatic section numbering and cross referencing are also possible.
|
|
|
|
\item{$\bullet$}
|
|
A powerful macro facility is built into \TeX. This lets you do some very
|
|
useful things, like creating an abbreviation for a commonly used phrase, or
|
|
defining a new command that will have varying effects depending on the
|
|
parameters it is given. A macro package can enhance \TeX\ by making it much
|
|
easier to generate a document in a predefined format.
|
|
\par % end the last paragraph BEFORE ending the group
|
|
} % \parskip will now revert to its previous value
|
|
|
|
\subhead{What CAN'T \TeX\ do?}
|
|
|
|
Complex graphics such as diagrams and illustrations pose
|
|
a major problem --- at the moment you have to leave an appropriate amount of
|
|
blank space and paste them in later.
|
|
Graphic facilities are the subject of current research.
|
|
|
|
\subhead{\TeX\ and VAX/VMS}
|
|
|
|
The \TeX\ source file used to generate this document is available for
|
|
inspection on any VAX node that has \TeX ---
|
|
just type `{\tt scroll tex\char'137 inputs:example.tex}'.
|
|
A few steps are needed to print such a file:
|
|
|
|
\item{(1)}
|
|
Type `{\tt tex example}' to ``compile'' the file.
|
|
(\TeX\ looks for a {\tt .tex} file by default. If it can't find the given
|
|
file in your current directory it will look in {\tt tex\char'137 inputs}.)
|
|
Two new files will be created in your current directory:
|
|
{\tt example.dvi} and {\tt example.lis}.
|
|
The former is a device independent description of the document;
|
|
the latter is simply a log of the \TeX\ run.
|
|
|
|
{\parskip=0pt % temporarily turn off \parskip
|
|
\item{(2)}
|
|
Type `{\tt dvitovdu example}' to preview the document on a terminal screen.
|
|
This program can be used to detect a variety of formatting problems,
|
|
saving both time and paper.
|
|
|
|
\item{(3)}
|
|
Type `{\tt imprint example}' to print the document.
|
|
(Note that the DVIto\kern-.15em VDU and IMPRINT commands
|
|
accept a {\tt .dvi} file by default).
|
|
|
|
} % restore \parskip
|
|
|
|
Detailed help on all these commands is available on-line --- try typing
|
|
`{\tt help tex}' to get started.
