1. Introduction.
FAQ No. 1. My computer just ate NINE high density diskettes' worth of
data. WHAT HAPPENED?
Answer: Installing teTeX on Chanel3, my Compaq laptop, was like
dropping a 20-foot concrete bridge section exactly into place from a
height of 50 feet. teTeX is a big package. Even so, it is a
moderately complete implementation of TeX 3.1415 and LaTeX 2e for
Linux systems. TeX is a big subject anyway, so you can expect to
spend the rest of your computing career keeping up-to-date on the
latest in the world of TeX. That is to say, installing and using
teTeX is not for the faint of heart. Nor is it for day trippers.
This package requires serious quality time.
Thomas Esser, the author of teTeX, has gone to great lengths to make
the package fast, complete, and easy to use. Because TeX is
implemented for practically every serious computer system in the
world---and quite a few ``non-serious'' ones---implementors must
provide the installation facilities for all of them. This accounts in
part for teTeX's size. It also accounts for the fact that the pieces
necessary to make a workable teTeX installation are spread all over
your friendly neighborhood CTAN archive.
CTAN is the Comprehensive TeX Archive Network, a series of anonymous
FTP sites which archive TeX programs, macros, fonts, and
documentation. You'll probably become familiar with at least one CTAN
site. In this document, a pathname like ~CTAN/contrib/pstricks means
``look in the directory contrib/pstricks of your nearest CTAN site.''
See section ``Appendix A'' for a current list of CTAN sites and their
mirror sites.
Fortunately, some considerate Linux Distribution implementors have
assembled the necessary pieces for us. teTeX comes with all the major
Linux distributions.
However, if you don't have the Slackware, RedHat, or Debian GNU/Linux
distribution, you can install teTeX from its official CTAN
distribution. In some cases this may be more desirable. See Section
3 for details.
If you already have teTeX installed on your system and want to jump
directly into figuring out how to use it, skip this section and the
next, and go directly to section ``Using teTeX''.
2. What is TeX? What is LaTeX? What is teTeX?
teTeX is an implementation of TeX for UNIX systems. It is the work of
Thomas Esser, te@informatik.uni-hannover.de. In the Linux versions of
teTeX, the executable programs themselves run under Linux and the
fonts are provided in form usable by the Linux-teTeX system. (The
sections covering teTeX installation concentrate on the i386 versions
of Linux. Installing teTeX for MkLinux or Linux for the Alpha should
require only substituting the appropriate binary-program archive in
the installation process.) The rest of the code, TeX and LaTeX
itself, is portable across various machines.
In addition to the executable programs, the distribution includes all
of the TeX and LaTeX package, metafont and its sources, bibtex(1),
makeindex(1), and all of the documentation... more than 4 megabytes'
worth. The documentation covers everything you will forseeably need
to know to get started. So, you should install all of the documents.
Not only will you eventually read them, the documents themselves
provide many examples of ``live'' TeX and LaTeX code.
In comparison with other implementations of TeX, the installation of
teTeX is almost trivial, even without the Linux distribution packages,
if you don't count the effort necessary acquire the distributions via
anonymous FTP or insert and remove several dozen distribution
diskettes by hand. If your teTeX distribution arrived on a CD-ROM,
even less effort is required to install it.
TeX is a typesetting system developed by Professor Donald Knuth of
Stanford University. It is a lower-level typesetting language that
powers all of the higher-level packages like LaTeX. Essentially,
LaTeX is a set of TeX macros which provide convenient, predefined
document formats for end users. If you like the formats provided by
LaTeX, you may never need to learn bare-bones TeX programming. The
difference between the two languages is like the difference between
assembly language and C. You can have the speed and flexibility of
TeX, or the convenience of LaTeX. Which brings us to the next answer,
Answer: You have it backwards! I want to know what exactly I need to
get before I can have TeX on my system!
It's important to remember that TeX only handles the typesetting part
of the document preparation. Generating output with TeX is like
compiling source code into object code, which still needs to be
linked. You prepare an input file with a text editor -- what most
people think of as ``word processing'' -- and typeset the input file
document with TeX to produce a device-independent output file, called
a .dvi file.
You also need output drivers for your printer and video display.
These output drivers translate TeX's .dvi output to display your
typeset document on the screen or on paper. This software is
collectively known as ``dviware.'' For example, TeX itself only makes
requests for fonts. It is up to the .dvi output translator to provide
the actual font to the display device if necessary, regardless of
whether it is the screen or a printer. This extra step may seem
overly complicated, but the abstraction allows documents to display
the same on different devices with no change to the original document.
In fact, much of TeX's, and therefore LaTeX's, complexity, arises from
its implementation of various font systems, and the way these fonts
are specified. A major improvement of LaTeX 2e over its predecessor
was the way users specify fonts, the former New Font Selection Scheme.
(See the sections ``Characters and type styles'' and ``Using
PostScript Fonts''.)
teTeX comes distributed with about a dozen standard fonts preloaded,
which is enough to get you started. Also provided are the font
metrics descriptions, in .tfm (TeX font metric) files. To generate
the other fonts you will need, it is simply a matter of installing the
metafont sources. teTeX's .dvi utilities will invoke metafont
automatically and generate the Computer Modern fonts you need, on-the-
fly.
By the way, the letters of the word ``TeX'' are Greek, tau-epsilon-
chi. This is not a fraternity. Instead, it is the root of the Greek
word, techne, which means art and/or science. ``TeX'' is not
pronounced like the first syllable in "Texas." The chi has no English
equivalent, but TeX is generally pronounced so that it rhymes with
``yecch,'' to use Professor Knuth's example from The TeXBook (see
below). When writing, "TeX," on character devices, always use the
standard capitalization, or the \TeX{} macro in typesetting. This is
how TeX is distinguished from other typesetting systems.
Speaking of typing, any of the editors which work under Linux---
nvi(1), jed(1), joe(1), jove(1), vi(1), vim(1), stevie(1), emacs(1),
microemacs---will work to prepare a TeX input file, as long as the
editor reads and writes plain-vanilla ASCII text. My preference is
emacs(1), the GNU version. There are several reasons for this:
o Emacs' TeX and LaTeX modes obviate the need for a stand-alone TeX
shell.
o Emacs can automatically insert TeX-style, ``curly quotes,'' as you
type, rather than the "ASCII-vanilla" kind.
o Emacs has integrated support for texinfo and makeinfo, a hypertext
documentation system.
o Emacs is widely supported. Version 19.34, for example, is included
in the major U.S. Linux distributions.
o Emacs does everything except butter the toast in the morning.
o Emacs is free.
There's a lot of software to assemble. In the meantime, you can start
in ``learning'' TeX and LaTeX. Remember that teTeX and the font
packages have been designed as two separate entities: The teTeX
executable programs and shell scripts, as distributed with Linux, have
been built specifically for the system, but the CM, DC, American
Mathematical Society, or other font distributions work on many
different platforms. While you are working on assembling the files,
you can take a few breaks to locate some of the documentation you will
need.
2.1. Resources for further information.
There are user manuals available both commercially and via the
Internet. Judging by the number of mentions they receive in the
Usenet comp.text.tex newsgroup, the most useful---and
definitive---commercially available texts for beginners are:
LaTeX: A Document Preparation System, by Leslie Lamport, 272 pp. If
you're using LaTeX instead of plain TeX (highly recommended), this is
the definitive reference.
If you must use plain TeX, The TeXBook by Donald Knuth, 483 pp., is
the definitive reference. It is also necessary if you plan to do any
serious class, package, or macro writing for LaTeX.
The LaTeX Companion, by Michel Goosens, Frank Mittelbach, and
Alexander Samarin, 530 pp., is more advanced than the Lamport, above.
If you are approaching TeX or LaTeX for the first time, you may feel
lost reading this. (I was.) However, when you need to add extension
packages, like PSNFSS (See the section titled, ``Using PostScript
fonts''.), or bibtex(1), a bibliography indexing program, this book is
one of the most highly regarded on the market.
At your nearest CTAN site you can retrieve these documents for free:
The Not So Short Introduction to LaTeX2e, by Tobias Oetiker, Hubert
Partl, Irene Hyna, and Elisabeth Schlegl, 69 pp. This wonderful
document is located at ~CTAN/packages/TeX/info/lshort/*.
You can get a PostScript or .dvi version of the document ready for
printing, or the native LaTeX document. There is also a version
available in German: lkurz.*. Make sure to read the README file before
assembling!
A Gentle Introduction to TeX: A Manual for Self-Study, by Michael
Doob, 91 pp. You can find this document at:
~CTAN:packages/TeX/info/gentle.tex. Almost of necessity, this document
covers less ground than its LaTeX counterpart, above. However, it
will get you to the same place as the LaTeX manuals. If you must use
plain TeX for your documents, this document clarifies many of the
complexities of plain TeX and makes its use almost easy.
``IMPRINT: The Newsletter of Digital Typography,'' edited by Robert
Kiesling. I realize that this is BLATANT and SHAMELESS self-
promotion. But, you should know anyway, that IMPRINT is a free,
ASCII-text newsletter which is available via e-mail. IMPRINT appears
approximately monthly and covers a broad range of text processing and
digital imaging topics, both beginning and advanced. Many of the
items covered apply directly or indirectly to TeX'ing. The emphasis
is on production of industry-standard typeset and printed material.
To subscribe to IMPRINT, send a brief, human-readable message to me at
imprint@macline.com.
The LaTeX Catalogue is a bibtex(1) database of available LaTeX
packages, compiled and maintained by Graham Williams. It's included
with teTeX, and the most recent version is available on the World Wide
Web. Do you need a package that prints borders, or makes margin
notes? You'll find that the package you need is listed here. The
LaTeX Catalogue is located in your local teTeX library in the
directory teTeX/texmf/doc/Catalog, and on the Web at
http://cbr.dit.csiro.au/~gjw. See section ``LaTeX extension packages
and other resources'' for further details about LaTeX packages.
Thomas Merz's Ghostscript Manual, which is the Ghostscript appendix of
his book, PostScript \& Acrobat/PDF: Applications, Troubleshooting,
and Cross-Platform Publishing. It is available from the Ghostscript
Home Page (see the section ``Ghosctscript V. 5.03''), or from Merz's
home page, http://www.muc.de/~tm/.
There are, of course, other guides available to using TeX and LaTeX.
They cover different aspects of these systems to varying degrees. The
reference documents cited above, however, are the most comprehensive
in scope that I have seen and are aimed at beginners (or near-
beginners).
If the going gets especially tough, you can probably do a little extra
shopping at Office Max, Office Depot, Staples, or your local
stationer, and pick up several reams of three-hole punched, photocopy
paper, two or three, three-inch binders, and some index tabs. When it
comes time to print the documents, you'll need a place to keep them,
and they seem to be more useful if they are kept on paper. This must
be one of the stranger phenomena of technical documentation.
You will note, however, that the references mentioned above are
hardware-independent. They won't tell you a thing about running teTeX
specifically. Many of them, in fact, refer to some mythical ``Local
Guide.'' This, and several of the documents that come bundled with
teTeX, comprise the less-than-mythical Local Guide to installing and
operating teTeX with Linux.
3. Installation notes.
All of the major Linux distributions include packaged versions of
teTeX, and each distribution has its own idiosyncrasies. The
packaging methods of each distribution are, for the most part,
incompatible. If you try to install teTeX from another distribution,
you may succeed in installing the package, but you're certain to mess
up the package-management database on your system. When installing
teTeX, please consult the section below that corresponds to your Linux
distribution.
Installing teTeX is surprisingly easy for a package of this magnitude.
This document covers only the major free U.S. Linux distributions,
because I haven't had time to obtain or install European Linux
distributions like S.u.S.E.
However, the generic, teTeX distribution isn't any harder to install
than the Linux packages. See section ``Generic CTAN distribution'',
below.
You should consider installing the generic teTeX distribution from the
CTAN archives if:
o Your system isn't based on one of the standard Linux distributions.
o You don't have root privileges on your system.
o You want or need to have the very latest version of teTeX, or
LaTeX.
o You don't have enough disk space available for a full installation.
o You want to install teTeX somewhere instead of the /usr file
system.
o You would like to share your teTeX installation with other UNIX
variants or platforms on a network. In this case, you should
strongly consider installing from the source distribution. See
section ``Installing the source distribution'', below.
o You want the latest versions of teTeX's public domain Type 1 fonts,
which are significantly better than the fonts included in earlier
releases.
A complete installation of the binary distribution requires 40-50 Mb
of disk space, and building the distribution from the source code
takes about 75 Mb, so you should make sure that the disk space is
available before you start. You don't need to have the gcc(1)
compiler or the X Windows System installed (although X certainly helps
because it is much easier to preview documents on-screen). All you
need is an editor that is capable of producing plain ASCII, text (see
section 2). What could be simpler?
Ghostscript V. 5.03 allows printing of PostScript documents on non-
PostScript printers, and allows previewing of PostScript documents on
VGA monitors and X Window System displays. If you already have a
PostScript printer, you won't need Ghostscript simply to print
PostScript documents. Ghostscript has many other capabilities,
however, which are beyond the scope of this HOWTO.
APSFILTER can automate document post processing and printing, and make
life with your printer a lot easier. See the section titled
``APSFILTER''.
For information on how to install a printer daemon and generally
configure printers for Linux, see the section titled ``The lpd(8)
daemon'', and consult the Printing-HOWTO.
3.1. Generic CTAN distribution, V. 0.4.
You can retrieve the files from one of the CTAN archives listed in
section ``Appendix A''. In the examples below, the files were
retrieved from the CTAN archive at ftp.tex.ac.uk.
3.1.1. Installing the binary distribution.
3.1.1.1. Minimal installation.
First, FTP to ftp.tex.ac.uk and cd to the directory
ctan/tex-archive/systems/unix/teTeX/distrib/
Retrieve the files
INSTALL.bin
install.sh
and place them in the top-level directory where you want to install
teTeX, for example, /var/teTeX if you plan to install teTeX in the
/var file system.
Print out the INSTALL.bin file. Keep this file handy, because it
describes how to install a minimal teTeX installation. The minimal
installation requires only 10-15 MB of disk space, but it is
recommended that you install the complete teTeX package if at all
possible. For a minimum installation, you'll need the files
ctan/tex-archive/systems/unix/teTeX/distrib/base/latex-base.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/base/tetex-base.tar.gz
You'll also need one of two archives which contain the executable
teTeX programs. Retrieve the archive file
ctan/tex-archive/systems/unix/teTeX/distrib/binaries/i386-linux.tar.gz
if your system uses the Linux ELF shared libraries, ld.so(1) of at
least version 1.73, and clibs of at least version 5.09. If it
doesn't, retrieve the archive
ctan/tex-archive/systems/unix/teTeX/distrib/binaries/i386-linuxaout.tar.gz
which is compiled for systems that use the older, a.out-format static
libraries.
Then, following the instructions in the file INSTALL.bin, execute the
command
sh ./install.sh
while in the top-level teTeX installation directory. (Make sure that
the teTeX archives are located there, too.) After a few moments, the
installation program will warn you that you are missing some of the
teTeX packages. However, if you're planning only a minimal teTeX
installation, you should ignore the warnings and proceed. To config-
ure the basic teTeX system, see section ``Base system configuration'',
below.
To install the remaining packages, see the next section.
3.1.1.2. Complete installation.
To perform a complete teTeX installation, retrieve the archive files
listed in the previous section, as well as the following files:
ctan/tex-archive/systems/unix/teTeX/distrib/doc/ams-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/bibtex-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/eplain-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/fonts-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/general-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/generic-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/latex-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/makeindex-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/metapost-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/programs-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/ams-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/dc-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/ec-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/misc-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/postscript-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/sauter-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/amstex.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/bibtex.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/eplain.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/latex-extra.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/metapost.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/pictex.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/pstricks.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/texdraw.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/xypic.tar.gz
All of these files should be placed in the top-level directory where
you want teTeX to reside. As with the minimal installation, execute
the command
sh ./install.sh
3.1.1.3. Base system configuration.
The install.sh script, after determining which teTeX archive series
are present, will present you with a menu of options. The only
setting you need to make at this point is to set the top-level
directory where you want teTeX installed, by selecting the ``D''
option. You must, of course, choose a directory in whose parent
directory you have write permissions. For example, if you are
installing teTeX in your home directory, you would specify the teTeX
installation directory as
/home/john.q.public/teTeX
and, after returning to the main menu, select ``I'' to proceed with
the installation. Note that the directory must not exist already: the
install.sh script must be able to create it.
An option which you should consider enabling, is setting an
alternative directory for generated fonts. Even if you plan to use
only PostScript-format, Type 1 scalable fonts, occasionally you'll
process a file that requires the Computer Modern fonts. Enabling this
option requires that you enter the directory to use. You must have
write permissions for the parent directory. Following the example
above, you could specify
/home/john.q.public/texfonts
or, if you want the generated fonts to be accessible by all users on
the system, specify a directory like
/var/texfonts
I would recommend that you not, however, use the default /var/tmp/tex-
fonts directory for this option, because the generated fonts could be
deleted after the next reboot, and the fonts will need to be generated
again the next time they're needed.
After you've selected the option ``I'', and install.sh has installed
the archives, set various permissions, and generated its links and
format files, the program will exit with a message telling you to add
the teTeX binary directory to your $PATH environment variable, and the
directories where the man pages and info files reside to your $MANPATH
and $INFOPATH environment variables. For example, add the statements
export PATH=$PATH:"/home/john.q.public/teTeX/bin"
export MANPATH=$MANPATH":/home/john.q.public/teTeX/man"
export INFOPATH$=INFOPATH":/home/john.q.public/teTeX/info"
to your ~/.bash_profile if you use bash(1) as your shell, or to your
~/.profile if you use another shell for logins.
Log out, and then log in again, so the environment variables are
registered. Then, run the command
texconfig confall
to insure that the installation is correct.
Next, you can configure teTeX for you specific hardware. See section
``Post-installation configuration details'', below.
3.1.2. Installing the source distribution.
To install teTeX V. 0.4 from the source code, ftp to a CTAN site like
ftp://ftp.tex.ac.uk and retrieve the files
ctan/tex-archive/systems/unix/teTeX/distrib/INSTALL.src
ctan/tex-archive/systems/unix/teTeX/distrib/sources/README.texmf-src
ctan/tex-archive/systems/unix/teTeX/distrib/sources/teTeX-lib-0.4pl8.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/sources/teTeX-src-0.4pl7.tar.gz
Read over the instructions in INSTALL.src, then su to root and unpack
the files in a directory for which you have read-write-execute
permissions.
Remember to use the p argument to tar(1), and also remember to unset
the noclobber option of bash(1). You can do this with the
counterintuitive command
set +o noclobber
Note that the argument +o to set unsets a variable, just exactly back-
wards from what you might expect.
The file teTeX-lib-0.4pl8.tar.gz will create the directory ./teTeX.
The file teTeX-src-0.4pl7.tar.gz will create the directory teTeX-
src-0.4 Print out the file INSTALL.src and keep it nearby for the
following steps. cd to the ./teTeX-src-0.4 directory, and, per the
instructions in the INSTALL.src file, edit ./Makefile. You need to
set the TETEXDIR variable to the absolute path of the parent teTeX
directory. This will be the subdirectory teTeX of the directory where
you unpacked the source and library archives. For example, if you
unpacked the archives in your home directory, you would set TETEXDIR
to
/home/john.q.public/teTeX
The rest of the Makefile options are pretty generic. With gcc(1) ver-
sion 2.7.2 and later, you should not need to make any further adjust-
ments unless you have a non-standard compiler and library setup, or
want the compiler to perform some further optimizations, or for some
other reason. Check that the USE_DIALOG, USE_NCURSES, and
HAVE_NCURSES variables are set correctly for your system, because the
dialog program needs the ncurses library to be installed. A
ncurses(3x) library is included in the source distribution, so the
default values in the Makefile should work fine. If you can't get
ncurses(3x) to compile or link, texconfig(1) can also be run from the
command line.
If you've done everything correctly up to this point, you should be
able to type make world in the top-level source directory, and relax
until the teTeX executables are built. This can take a few hours.
After the build has completed, set the environment variables $PATH,
$MANPATH, and $INFOPATH to include the teTeX directories. The
statements which would be added to the file ~/.bash_profile, in the
example, above, would be
export PATH=$PATH":/home/john.q.public/teTeX/bin/i386-linux"
export MANPATH=$MANPATH":/home/john.q.public/teTeX/man"
export INFOPATH=$INFOPATH":/home/john.q.public/teTeX/info"
The $PATH variable is different in the source distribution than in the
binary distribution. Note that here the path to the binaries is
teTeX/bin/i386-linux instead of simply teTeX/bin as in the binary dis-
tribution.
At this point you can run texconfig confall to ensure that the paths
have been set correctly, and then proceed to configure teTeX as in the
binary distribution. See the section ``Post-installation
configuration details'', below.
3.2. Linux packages.
3.2.1. Slackware 3.2.
First, ftp to your nearest Linux archive site. Mine is
wuarchive.wustl.edu. Then find the directory with the Slackware
distribution diskettes. On wuarchive.wustl.edu, this is
systems/linux/sunsite/distributions/Slackware/slakware/.
Linux sites which mirror sunsite.unc.edu will store these diskettes in
the directory distributions/Slackware/slakware/. teTeX, the full
package, is contained on the Slackware disk series t. So, grab all
nine disks' worth of the t series, disks t1 - t9. Be sure to keep them
in order, too. Either store the files in separate subdirectories
labeled t1 - t9 on a hard drive partition, or on diskettes, and label
the diskettes t1 through t9. We're going to install them by hand.
This isn't difficult. The Slackware installer creates the directories
and unpacks the files. It also provides descriptions of each module
in the distribution, which allows you to decide whether you want to
install it or not. In the case of teTeX, however, you are simply
going to install everything, because that's what you should do anyway.
Let's assume that you have all nine diskettes' worth of the Slackware
teTeX distribution ready at hand, organized as described above.
You'll have a lot of files which have the extension .tgz. This is
shorthand for a tar(1) archive compressed with gzip(1). The names all
fit the 8+3 filename limitations of MS-DOG. Aren't you glad you
decided to scrap your DOG partitions and install Linux instead? You
can use a MS-DOG hard disk partition or DOG-format diskettes to store
the files. The archives also begin with the letters tb, td, or tm,
and so on, which is the implementors' shorthand for TeX binary, TeX
documentation, TeX macro, and so on. The difference to you is
academic, because you'll be installing everything anyway.
Simply fire up the Slackware install utility. You needn't concern
yourself with reconfiguring the system, so select the option to add
new software. Select the appropriate source media (diskettes, HD
partition, or CD-ROM), specify that you want to install the Slackware
t series, and that you do not want to be prompted -- simply install
all the archives on the Slackware t series diskettes. You'll be
prompted to insert each diskette in the floppy drive if you're
installing from diskettes. If you're installing from a hard drive or
CD-ROM, no more intervention is required by you.
3.2.1.1. Manual Slackware install.
This section is for people who, for one reason or another, would like
to install teTeX manually from a Linux package.
Let's assume that you've assembled the Slackware teTeX distribution on
floppy diskettes labelled t1 thru t9. Mount the t1 diskette like this
mount /dev/fd0 /mnt
if your Linux configuration is a standard configuration. Actually,
any mount point will do. You'll simply need to substitute the appro-
priate path spec in the next few steps.
The next thing you want to do is create the teTeX top-level directory.
teTeX's internal paths are specified relative to its binary program
files, but the Slackware distribution is archived relative to the root
directory. So the top-level teTeX directory is:
/usr/lib/teTeX
For each of the .tgz archive files in the distribution, copy the
archive file to the /usr/lib/teTeX directory and repeat the following
commands:
You should be logged in as root and in the top-level directory, /, for
these steps. I've used the tb-xfig.tgz archive for demonstration
purposes. Of course, you'll want to substitute the name of whichever
archive you're unpacking.
cp /mnt/tb-xfig.tgz /usr/lib/teTeX
tar -zxvf /usr/lib/teTeX/tb-xfig.tar # v to see what's going on!
rm /usr/lib/teTeX/tb-xfig.tgz
Most Slackware packages that I've seen also include an install script,
which the Slackware installer executes after unpacking the files.
Look in the directory /install after you've unpacked the files. If
there's a script there called doinst.sh, execute that, as root, by
typing
sh < /install/doinst.sh
It may be alarming to watch all those filenames scrolling of the top
of the screen as the archives are unpacked. Relax! Take a break, and
freshen up your coffee (or grab another JOLT from the refrigerator, or
otherwise replenish whatever you're drinking). There's only a few
more steps you need to perform to install teTeX. They're covered in
Section 4.
3.2.2. Debian GNU/Linux, V. 1.3.
Installing teTeX from Debian packages is truly trivial. ftp the most
recent stable versions of the teTeX archive files from ftp.debian.org.
The teTeX distribution is located in the directory
pub/debian/bo/binary-i386/tex
Retrieve the following Debian archive files via anonymous FTP (remem-
bering to set binary mode for the transfers).
tetex-base_0.4pl6-5.deb
tetex-bin_0.4pl6-8.deb
tetex-dev_0.4pl6-8.deb
tetex-doc_0.4pl6-1.deb
tetex-extra_0.4pl6-4.deb
Once the files are safely transferred to your local hard disk, su to
root, and install them using the dpkg(1) utility:
dpkg -i tetex-base_0.4pl6-5.deb
dpkg -i tetex-bin_0.4pl6-8.deb
dpkg -i tetex-dev_0.4pl6-8.deb
dpkg -i tetex-doc_0.4pl6-1.deb
dpkg -i tetex-extra_0.4pl6-4.deb
Installation will take some time, because the Debian archives contain
the shell scripts necessary to check for old TeX installations, build
the TeX and LaTeX .fmt files, build the path-searching database, and
see to other configuration details. However, once they are finished,
you should have an operational teTeX installation that needs only to
be configured for the details of your local system; see section
``Post-installation configuration details''.
3.2.3. RedHat V. 4.2.
Presumably, you could install only selected portions of the teTeX
RedHat distribution, but consistent with the philosophy of the other
sections, it is assumed that you will eventually need all of the
facilities provided by teTeX, and so you should install the complete
distribution.
To install teTeX from RedHat Linux RPM packages, under RedHat Linux v.
4.2, ftpto sunsite.unc.edu and cd to the directory
pub/Linux/distributions/redhat/current/i386/RedHat/RPMS/
Set binary mode for the transfers and retrieve the following files:
tetex-0.4pl8-5.i386.rpm
tetex-latex-0.4pl8-5.i386.rpm
tetex-afm-0.4pl8-5.i38 6.rpm
tetex-dvilj-0.4pl8-5.i386.rpm
tetex-dvips-0.4pl8-5.i386.rpm
tetex-xdvi-0.4pl8-5.i386.rpm
tetex-texmf-src-0.4pl8-5.i386.rpm
This last file may not be strictly necessary. It contains the LaTeX
sources, if you want to install LaTeX yourself. If you're thinking of
upgrading LaTeX independently of the binaries in the future, this
archive could be useful to have around:
Simply install the files above in the order given, using the rpm -i
command, and proceed to the section, ``Post-installation configuration
details''.
3.3. Ghostscript V. 5.03.
Ghostscript development is rapid, and the changes which are
incorporated into every new version are significant. Therefore, it's
worth the effort to install the version of Ghostscript that is
available on its home page, http://www.cs.wisc.edu/~ghost.
At the time of this writing, the current version is 5.03. The
Ghostscript archive for Linux is composed of the following files:
ghostscript-5.03gnu.tar.gz
ghostscript-5.03jpeg.tar.gz
ghostscript-5.03libpng.tar.gz
ghostscript-5.03zlib.tar.gz
ghostscript-fonts-std-5.03.tar.gz
ghostscript-fonts-other-5.03.tar.gz
What is Ghostscript, and why do you need it? Technically, Ghostscript
is a Raster Image Processor. It translates PostScript code into many
common, bit-mapped formats, like those understood by your printer or
screen, whether or not they are equipped with PostScript. In practi-
cal terms, Ghostscript allows you to use Type 1 fonts, and mix text
and graphics on any printer or video display that Ghostscript knows
about.
The quality of the fonts which come with the program have improved
steadily in the last several versions as well. Or maybe it's that
more recent versions of Ghostscript have improved font rendering. In
either case, this is of real benefit for Linux users, who may not be
able to spend hundreds of dollars on commercial fonts. Because
Ghostscript is able to read the font requests made by dvips(1),
Ghostscript's font library provides the fonts, not teTeX. But the
font metrics files for Ghostscript's font library, which have the
extension .afm, are already included in the teTeX distribution.
For information about using Ghostscript, see the file use.txt in the
Ghostscript distribution, and the Linux Documentation Project's
Printing-HOWTO. There's also a Ghostscript manual available from the
Internet. See section ``Resources for further information''
Or, install APSFILTER and let that run Ghostscript automatically.
(See section ``APSFILTER'').
A final, significant note: I would recommend that you compile
Ghostscript for your own system, if possible. Combining different
versions of Ghostscript and svgalib can quickly become confusing. The
version of Ghostscript which is included in the Slackware AP set is
version 2.6.2 and does not have X support compiled in. You might also
have trouble finding the correct svgalib versions for it. There is
supposedly a version of Ghostscript with X11 support in the Slackware
XAP distribution series, and presumably in the other Linux
distributions, though I haven't tried them. Compiling Ghostscript for
your own system is far easier, it seems to me.
It's also important to remember that there are two Ghostscript
releases in distribution: the commercial, Aladdin Ghostscript, and GNU
Ghostscript, which lags behind Aladdin Ghostscript by several years.
This is due to Ghostscript's unique licensing arrangement. See the
Printing-HOWTO for more information about Ghostscript licensing.
svgalib support for GNU Ghostscript 3.33 is included in a small
archive which contains a .diff file. Ghostscript 3.33 for X is also
configured for JPEG support, so you should include the JPEG library
sources as well. The relevant archives can be found at any GNU
distribution site, like ftp://prep.ai.mit.edu/pub/gnu.
3.4. APSFILTER.
There are software packages which will simplify your life, and
APSFILTER is one of them. Written by Andreas Klemm, APSFILTER works
with any BSD-compatible printer daemon (which means that you have the
lpd(8) program and an /etc/printcap file; see below), and provides
transparent printer support for ASCII, DVI, and PostScript files, as
well as files compressed by gzip(1), compress(1), and other data
compression software.
Once you have successfully installed APSFILTER, you can print a
PostScript file to whatever printer you have, by typing
lpr file.ps
Or, to print an ASCII file without PostScript translation, you can
type
lpr -Praw file.asc
Amazing.
APSFILTER is surprisingly easy to install, considering that it works
with many disparate elements of your system. Installing the generic
APSFILTER distribution, however, does require that you have a current
gcc(1) compiler on hand, because APSFILTER builds some of its filters
during installation. Some distributions of Linux, however, provide a
pre-built version, so check your specific distribution first.
In any event, you will need a correctly installed Ghostscript and
lpd(8) installation for APSFILTER to work. The most recent APSFILTER
is located in the Linux Archives at
ftp://sunsite.unc.edu/pub/Linux/system/printing/.
3.5. The lpd(8) daemon.
There are wide variations in printers and configurations. Setting up
a working printer daemon is no mean feat. If you're using teTeX on an
individual system, you could simply dump the output to the printer
device driver file, but this is less than desirable. You lose the
filtering capabilities of the printer daemon. If you're printing on a
network, having a working printer daemon is a must.
The basic UNIX program for printer management on BSD-style systems is
lpd(8). When you print a file with lpr(1) you are really sending the
file to a print queue. lpd(8) prints files in the order they're
queued. Other printer utilities include lpq(1), which displays the
contents of the print queue, and lprm(1), which removes (dequeues)
files from the print queue.
The printer daemon can perform other tasks, like transparently
filtering output from various programs (using filter programs like
APSFILTER, above), accept print jobs from other machines on a network,
send print jobs to various printers if you have more than one
connected, and hold print output until you've refilled the paper feed
tray.
The Printing-HOWTO explains the process of setting up a working
printer daemon in detail. Many Linux distributions already have
configured lpd(8) suites. Check there first, because it will save you
considerable work. They're usually archived, strangely enough, using
the name lpr, so search for that program. There is also a printer
daemon suite available from the Linux archives, at
ftp://sunsite.unc.edu/pub/Linux/system/printing.
4. Post-installation configuration details.
The first thing you'll want to do is look at Thomas Esser's README
file. It contains a lot of hints on how to configure teTeX for your
output device (i.e., printer). The README file is located in the
directory
/usr/lib/teTeX/texmf/doc/tetex
Read the file over with the command (the path in the following exam-
ples is that of the Slackware distribution):
less /usr/lib/teTeX/texmf/doc/tetex/README
or, print it out with the command
cat /usr/lib/teTeX/texmf/doc/tetex/README >/dev/lp0
assuming that your printer is connected to /dev/lp0. Substitute the
device driver file that your printer is connected to, as appropriate.
Or, better still, print it using the lpr(1) command:
lpr /usr/lib/teTeX/texmf/doc/tetex/README
You should have installed the printer daemon that is included with
your distribution of Linux. If not, do that now, per the instructions
that come with the package. If you don't have one of the packages, or
want to install a printer daemon yourself, see section ``The lpd(8)
daemon''
Print out the teTeX-FAQ. Keep the FAQ handy because it contains useful
hints for configuring teTeX's output drivers for your printer. We'll
get to that in a moment. In more recent releases of teTeX, the teTeX-
FAQ is viewable via the texconfig utility.
Next, you want to define a directory to store your own TeX format
files. teTeX searches the directories listed by the $TEXINPUTS
environment variable for local TeX input files. On Chanel3, I added
the line
export TEXINPUTS=".:~/texinputs:"
to the system-wide /etc/profile file. Individual users can set their
own local $TEXINPUTS directory, by adding the line in their ~/.profile
or ~/.bash_profile if bash(1) is the default shell. The $TEXINPUTS
environment variable tells teTeX to look for users' individual TeX
style files in the ~/texinputs directories under each user's home
directory. It is critical that a colon appear before and after this
directory. teTeX is going to append its own directory searches to
your own. You want to have teTeX search the local format files first,
so it uses the local versions of any of the standard files you have
edited.
Add the /usr/lib/teTeX/bin directory to the system-wide path if you're
installing teTeX as root. Again, if you're installing a personal copy
of teTeX, add the directory where the teTeX binaries are located to
the front your $PATH with the following line in your ~/.profile or
~/.bash_profile:
export PATH="~/tetex/bin:"$PATH
Now, log in as root and run texconfig per the instructions in the
teTeX-FAQ and choose the printer that is attached to your system.
Make sure that you configure teTeX for both the correct printer and
printer resolution.
Finally, run the texhash program. This ensures that teTeX's internal
database is up to date. The database is actually a ls-lR file. You
must run texhash every time you change the system configuration, or
teTeX will not be able to locate your changes.
4.1. What if my printer isn't included?
The teTeX distribution comes with only a limited selection of DVI
output drivers: dvips(1), drivers for Hewlett Packard LaserJets, and
nothing else. You have two options if you have a printer which isn't
LaserJet-compatible: You can use dvips(1) and Ghostscript, which I
would recommend anyway, for reasons already mentioned, or you can
investigate other dviware sources.
A limited number of DVI drivers have been ported to Linux and are
available as pre-built binaries. They are located in the Linux
archives at ftp://sunsite.unc.edu/pub/Linux/apps/tex/dvi/.
The master dviware libraries are maintained at the University of Utah
archives. If you can't find a DVI driver there that supports your
printer, chances are that it doesn't exist. You can also write your
own DVI driver using the templates available there. The library's URL
is ftp://ftp.math.utah.edu/pub/tex/dvi/.
5. Using teTeX.
Theoretically, at least, everything is installed correctly and is
ready to run. teTeX is a very large software package. As with any
complex software package, you'll want to start by learning teTeX
slowly, instead of being overwhelmed by its complexity.
At the same time, we want the software to do something useful. So
instead of watching TeX typeset
``Hello, World!''
as Professor Knuth suggests in the The TeXBook, we'll produce a couple
of teTeX's own documents in order to test it.
The next section, ``Printing the documentation'', is really a tutorial
for operating teTeX. It covers printing the documentation included
with teTeX (which is in LaTeX and .dvi format, of course). The
following section, ``TeX and LaTeX commands'', is more of a
``cookbook'' than a tutorial. It discusses how to format LaTeX
documents, and covers a few of the commands and environments of the
more commonly used document classes.
The section ``LaTeX extension packages and other resources'' tells how
to use the many pre-existing LaTeX packages to customize documents to
your specifications.
5.1. Printing the documentation.
You should be logged in as root the first few times you run teTeX. If
you aren't, metafont may not be able to create the necessary
directories for its fonts. The texconfig program includes an option
to make the font directories world-writable, but if you're working on
a multi-user system, security considerations may make this option
impractical or undesirable.
In either instance, if you don't have the appropriate permissions to
write to the directories where the fonts are stored, metafont will
complain loudly because it can't make the directories. You won't see
any output because you have a bunch of zero-length font characters.
This is no problem. Simply log out, re-login as root, and repeat the
offending operation.
The nice thing about teTeX is that, if you blow it, no real harm is
done. It's not like a compiler, where, say, you will trash the root
partition if a pointer goes astray. What, you haven't read the teTeX
manual yet? Of course you haven't. It's still in the distribution,
in source code form, waiting to be output.
So, without further delay, you will want to read the teTeX manual.
It's located in the directory
/usr/lib/teTeX/texmf/doc/tetex.
The LaTeX source for the manual is called TETEXDOC.tex. (The .tex
extension is used for both TeX and LaTeX files. Some editors, like
emacs(1), can tell the difference.) There is also a file TETEXDOC.dvi
included with the distribution, which you might want to keep in a safe
place---say, another directory ---in case you want to test your .dvi
drivers later. With that out of the way, type
latex TETEXDOC.tex
LaTeX will print several warnings. The first,
LaTeX Warning: Label(s) may have changed. Rerun to get the
cross-references right.
is standard. It's common to build a document's Table of Contents by
LaTeXing the document twice. So, repeat the command. The other warn-
ings can be safely ignored. They simply are informing you that some
of the FTP paths mentioned in the documentation are too wide for their
alloted spaces. (If you're really inquisitive, look at one of the TeX
references for a discussion of \hbox and \vbox.)
teTeX will have generated several files from TETEXDOC.tex. The one
that we're interested in is TETEXDOC.dvi. This is the device-
independent output which you can send either to the screen or the
printer. If you're running teTeX under the X Windows System, you can
preview the document with xdvi(1).
For the present, let's assume that you have a HP LaserJet II. You
would give the command
dvilj2 TETEXDOC.dvi
which will write a PCL output file from TETEXDOC.dvi, including soft
fonts which will be downloaded to the LaserJet. This is not a feature
of TeX or LaTeX, but a feature provided by dvilj2(1). Other .dvi
drivers provide features which are relevant to the devices they sup-
port. dvilj2(1) will fill the font requests which were made in the
original LaTeX document with the the closest equivalents available on
the system. In the case of a plain-text document like TETEXDOC.tex,
there isn't much difficulty. All of the fonts requested by TETEX-
DOC.tex will be generated by metafont, which is automatically invoked
by dvilj2(1) and generates the fonts if they aren't already present.
(If you're running dvilj2(1) for the first time, the program needs to
generate all of the fonts, which could take up to several days if
you're using a really slow machine.) There are several options which
control font generation via dvilj2(1); they're outlined in the manual
page. At this point, you shouldn't need to operate metafont directly.
If you do, then something has gone awry with your installation. All
of the .dvi drivers will invoke metafont directly via the kpathsea
path-searching library---also beyond the scope of this document---and
you don't need to do any more work with metafont for the present---all
of the metafont sources for the Computer Modern font library are pro-
vided.
You can print TETEXDOC.lj with the command
lpr TETEXDOC.lj
You may need to install a printer filter that understands PCL. Look
at the Printing-HOWTO for details.
The nine-page teTeX Guide provides some useful information for further
configuring your system, some of which I have mentioned, much which
this document doesn't cover.
Some of the information in the next section I haven't been able to
test, because I have a non-PostScript HP Deskjet 400 color ink jet
printer connected to Chanel3's parallel port. However, not owning a
PostScript printer is no barrier to printing text and graphics from
your text documents. See the section ``Ghostscript'' to install
Ghostscript, if it isn't already installed on your system.
5.2. TeX and LaTeX commands.
5.2.1. Document structure.
Preparing documents for TeX typesetting is easy. Make sure there's a
blank line between the paragraphs of a plain text file, and run file
through the TeX program with the command
TeX your_text_file
The result will be a file of the same base name and the extension
.dvi. The text is set in 10-point, Computer Modern Roman, single-
spaced, with justified left and right margins. If you receive error
messages from special characters like dollar signs, escape them with a
backslash character, \, and run TeX on the file again. You should be
able to process the resulting file with the .dvi file translator of
your choice (see above) to get printed output.
The only other peculiarity of TeX input files is to make sure that you
use opening and closing quotes, which are denoted in the input file
with the grave accent and single quote characters. Emacs' TeX mode
will do this for you automatically.
"These are ascii-type quotes."
``These are `TeX-style' quotes.''
You can consult a guide like A Gentle Introduction to TeX, described
above, for hints on how to make modifications to the default TeX page
format.
Documents formatted for LaTeX have a few more rules, but with complex
documents, LaTeX can greatly simplify the formatting process.
Essentially, LaTeX is a document markup language which tries to
separate the output style from the document's logical content. For
example, formatting a section heading with TeX would require
specifying 36 points of white space above the heading, then the
heading itself set in bold, 24-point type, then copying the heading
text and page number to the Table of Contents, then leaving 24 points
of white space after the heading. By contrast, LaTeX has the
\section{} command, which does all of the work for you. If you need
to change the format of the section headings throughout your document,
you can change the definition of \section{} instead of the text in the
document. You can see where this would save hours of reformatting for
documents of more than a dozen pages in length.
All LaTeX documents have three sections: a preamble, the body text,
and a postamble. These terms are standard jargon and are widely used
by TeXperts.
The preamble, at a minimum, specifies the type of document to be
produced---the document class---and a statement which signals the
beginning of the document's body text. For example:
\documentclass{article}
\begin{document}
The document's postamble is usually very simple. Except in special-
ized cases, it contains only the statement:
\end{document}
Note the \begin{document} and \end{document} pairing. In LaTeX, this
is called an environment. All text must appear within an environment,
and many commands are effective only in the environments in which
they're called. The document environment is the only instance where
LaTeX enforces this convention, however. That is, it's the only envi-
ronment that is required in a document. (An exception is letter
class, which also requires you to declare \begin{letter} and
\end{letter}. See the section ``Letters''.) However, many formatting
features are specified as environments. They're described in the fol-
lowing sections.
The document classes can be called with arguments. For example,
instead of the default, 10-point type used as the base point size, as
in the previous example, we could have specified
\documentclass[12pt]{article}
to produce the document using 12 points as the base point size. The
document class, article, makes the necessary adjustments.
There are a few document classes which are commonly used. They're
described below. The report class is similar to article class, but
produces a title page and starts each section on a new page. The
letter class includes special definitions for addresses, salutations,
and closings, a few of which are described below.
You can include canned LaTeX code, commonly known as a package, with
the \usepackage{} command.
\usepackage{fancyhdr}
The command above would include the LaTeX style file fancyhdr.sty from
one of the TEXINPUTS directories, which you and teTeX specified during
installation and setup processes.
\documentclass{article}
\usepackage{fancyhdr}
\begin{document}
Note that the \usepackage{} declarations are given before the
\begin{document} statement; that is, in the document preamble.
fancyhdr.sty extends the \pagestyle{} command so that you can create
custom headers and footers. Most LaTeX document classes provide
headers and footers of the following standard page styles:
\pagestyle{plain} % default pages style -- page number centered at
% the bottom of the page.
\pagestyle{empty} % no headers or footers
\pagestyle{headings} % print section number and page number at the
% top of the page.
\pagestyle{myheadings} % print custom information in the page heading.
Everything on a line to the right of the percent sign is a comment.
The \pagestyle{} command doesn't take effect until the following page.
To change the headers and footers on the current page, use the command
\thispagestyle{the_pagestyle}
5.2.2. Characters and type styles.
Character styles are partially a function of the fonts specified in
the document. However, bold and italic character emphasis should be
available for every font present on the system. Underlining, too, can
be used, though its formatting presents special problems. See section
``LaTeX extension packages and other resources'', below.
You can specify text to be emphasized in several ways. The most
portable is the \em command. All text within its scope is italicized
by default. For example:
This word will be {\em emphasized.}
If you have italicized text that runs into text which is not itali-
cized, you can specify an italic correction factor to be used. The
command for this is \/; that is, a backslash and a forward slash.
This example {\em will\/} print correctly.
This example will {\em not} print correctly.
Slightly less portable, but still acceptable in situations where
they're used singly, are the commands \it, \bf, and \tt, which specify
that the characters within their scope be printed using italic, bold,
and monospaced (teletype) typefaces, respectively.
{\tt This text will be printed monospaced,}
{\it this text will be italic,} and
{\bf this text will be bold\dots} all in one paragraph.
The command \dots prints a series of three periods for ellipses, which
will not break across a line.
The most recent version of LaTeX, which is what you have, includes
commands which account for instances where one emphasis command would
supersede another.
This is {\it not {\bf bold italic!}}
What happens is that teTeX formats the text with the italic typeface
until it encounters the \bf command, at which point it switches to
boldface type.
To get around this, the NFSS scheme of selecting font shapes requires
three parameters for each typeface: shape, series, and family. Not
all font sets will include all of these styles. LaTeX will print a
warning, however, if it needs to substitute another font.
You can specify the following font shapes:
\textup{text} % upright shape (the default)
\textit{text} % italic
\textsl{text} % slanted
\textsc{text} % small caps
These are the two series that most fonts have:
\textmd{text} % medium series (the default)
\textbf{text} % boldface series.
There are generally three families of type available.
\textrm{text} % roman (the default)
\textsf{text} % sans serif
\texttt{text} % typewriter (monospaced, Courier-like)
Setting font styles using these parameters, you can combine effects.
\texttt{\textit{This example likely will result in a font
substitution, because many fonts don't include a typewriter italic
typeface.}}
The font family defaults to Computer Modern, which is a bit-mapped
font. Other font families are usually PostScript-format Type 1 fonts.
See section ``Using PostScript fonts'' for details on how to specify
them.
There are also many forms of accents and special characters which are
available for typesetting. This is only a few of them. (Try
typesetting these on your own printer.)
\'{o} \`{e} \^{o} \"{u} \={o} \c{c} `? `!
\copyright \pounds \dag
Finally, there are characters which are used as meta- or escape char-
acters in TeX and LaTeX. One of them, the dollar sign, is mentioned
above. The complete set of metacharacters, which need to be escaped
with a backslash to be used literally, is:
# $ % & _ { }
There are also different alphabets available, like Greek and Cyrillic.
LaTeX provides many facilities for setting non-English text, which are
covered by some of the other references mentioned here
5.2.3. Margins and line spacing.
Changing margins in a TeX or LaTeX document is not a straightforward
task. A lot depends on the relative indent of the text you're trying
to adjust the margin for. The placement of the margin-changing
command is also significant.
For document-wide changes to LaTeX documents, the \evensidemargin and
\oddsidemargin commands are available. They affect the left-hand
margins of the even-numbered and odd-numbered pages, respectively.
For example,
\evensidemargin=1in
\oddsidemargin=1in
adds on inch to the left-hand margin of the even and odd pages in
addition to the standard one-inch, left-hand margin. These commands
affect the entire document and will shift the entire body of the text
right and left across a page, regardless of any local indent, so
they're safe to use with LaTeX environments like verse and list.
Below is a set of margin-changing macros which I wrote. They have a
different effect than the commands mentioned above. Because they use
plain TeX commands, they're not guaranteed to honor the margins of any
LaTeX environments which may be in effect, but you can place them
anywhere in a document and change the margins from that point on.

%%
%% (End of margins macros.}
Place this code in a file called margins.sty in your local $TEXINPUTS
directory. The commands are explained in the commented section of the
file. To include them in a document, use the command
\usepackage{margins}
in the document preamble.
While we're on the subject, if you don't want the right margin to be
justified, which is the default, you can tell LaTeX to use ragged
right margins by giving the command:
\raggedright
Setting line spacing also has its complexities.
The baselineskip measurement is the distance between lines of text.
It is given as an absolute measurement. For example,
\baselineskip=24pt
or even better:
\setlength{\baselineskip}{24pt}
The difference between the two forms is that setlength will respect
any scoping rules that may be in effect when you use the command.
The problem with using baselineskip is that it also affects the
distance between section headings, footnotes, and the like. You need
to take care that baselineskip is correct for whatever text elements
you're formatting. There are, however, LaTeX macro packages, like
setspace.sty, which will help you in these circumstances. See section
``LaTeX extension packages and other resources''.
5.2.4. Document classes.
LaTeX provides document classes which provide standardized formats for
documents. They provide environments to format lists, quotations,
footnotes, and other text elements. Commonly used document classes
are covered in the following sections.
5.2.4.1. Articles and reports.
As mentioned above, the article class and the report class are
similar. The main differences are that the report class creates a
title page by default and begins each section on a new page. Mostly,
though, the two document classes are similar.
To create titles, abstracts, and bylines in these document classes,
you can type, for example,
\title{The Breeding Habits of Cacti}
\author{John Q. Public}
\abstract{Description of how common desert cacti search
for appropriate watering holes to perform their breeding
rituals.}
in the document preamble. Then, the command
\maketitle
given at the start of the text, will generate either a title page in
the report class, or the title and abstract at the top of the first
page, in the article class.
Sections can be defined with commands that include the following:
\section
\subsection
\subsubsection
These commands will produce the standard, numbered sections used in
technical documents. For unnumbered sections, use
\section*
\subsection*
\subsubsection*
and so on.
LaTeX provides many environments for formatting displayed material.
You can include quoted text with the quotation environment.
\begin{quotation}
Start of paragraph to be quoted...
... end of paragraph.
\end{quotation}
For shorter quotes, you can use the quote environment.
To format verse, use the verse environment.
\begin{verse}
Because I could not stop for death\\
He kindly stopped for me
\end{verse}
Notice that you must use the double backslashes to break lines in the
correct places. Otherwise, LaTeX fills the lines in a verse environ-
ment, just like any other environment.
Lists come in several flavors. To format a bulleted list, the list
environment is used:
\begin{list}
\item
This is the first item of the list.
\item
This is the second item of the list...
\item
... and so on.
\end{list}
A numbered list uses the enumerate environment:
\begin{enumerate}
\item
Item No. 1.
\item
Item No. 2.
\item
\dots
\end{enumerate}
A descriptive list uses the description environment.
\begin{description}
\item{Oven} Dirty, needs new burner.
\item{Refrigerator} Dirty. Sorry.
\item{Sink and drainboard} Stained, drippy, cold water faucet.
\end{description}
5.2.4.2. Letters.
The letter class uses special definitions to format business letters.
The letter environment takes one argument, the address of the letter's
addressee. The address command, which must appear in the document
preamble, defines the return address. The signature command defines
the sender's name as it appears after the closing.
The LaTeX source of a simple business letter might look like this.
\documentclass[12pt]{letter}
\signature{John Q. Public}
\address{123 Main St.\\Los Angeles, CA. 96005\\Tel: 123/456-7890}
\begin{document}
\begin{letter}{ACME Brick Co.\\100 Ash St.\\San Diego, CA 96403}
\opening{Dear Sir/Madam:}
With regard to one of your bricks that I found on my living room
carpet surrounded by shards of my broken front window...
(Remainder of the body of the letter.)
\closing{Sincerely,}
\end{letter}
\end{document}
Note that the addresses include double backslashes, which specify
where the line breaks should occur.
5.3. LaTeX extension packages and other resources.
We mentioned above that using underlining as a form of text emphasis
presents special problems. Actually, TeX has no problem underlining
text, because it is a convention of mathematical typesetting. In
LaTeX, you can underline words with the command:
\underline{text to be underlined}
The problem is that underlining will not break across lines, and, in
some circumstances, underlining can be uneven. However, there is a
LaTeX macro packagem, ready-made, that makes underlining the default
mode of text emphasis. It's called ulem.sty, and is one of the many
contributed LaTeX packages that are freely available via the Internet.
To use ulem.sty, include the command
\usepackage{ulem}
in the document preamble.
The LaTeX Catalogue provides one-line descriptions of every LaTeX
package available, their names and CTAN paths. For the URL of the
most current edition of the Catalogue, see the section ``Resources for
further information''.
The packages which are available for LaTeX include:
ifthen
Include conditional statements in your documents.
initials
Defines a font for initial dropped capitals.
sanskrit
Font and preprocessor for producing documents in Sanskrit.
recipe
A LaTeX2e class to typeset recipes.
refman
Variant report and article styles.
To make the path given in the Catalogue into a fully-qualified URL,
concatenate the path to the hostname URL and top-level path of the
CTAN archive you wish to contact. For example, the top-level CTAN
directory of the site ftp.tex.ac.uk is ctan/tex-archive. The complete
URL of the directory of the refman package would be:
ftp://ftp.tex.ac.uk/ctan/tex-archive/ +
macros/latex/contrib/supported/refman =
ftp://ftp.tex.ac.uk/ctan/tex-archive/macros/latex/contrib/supported/refman/
Some packages have more than one file, so only the path to the pack-
age's directory is given.
When you have the URL in hand, you can retrieve the package from one
of the CTAN archive sites listed in section ``Appendix A''. You can
download a complete list of the archive's contents as the file
FILES.byname, in the archive's top-level directory. You can also
search the archive on line for a keyword with the ftp(1) command
quote site index <keyword>
6. Mixing text and graphics with dvips(1) .
In general, this section applies to any TeX or LaTeX document which
mixes text and graphics. teTeX, like most other TeX distributions, is
configured to request Computer Modern fonts by default. When printing
documents with Type 1 scalable fonts or graphics, font and graphics
imaging is the job of dvips(1). dvips(1) can use either Computer
Modern bit mapped fonts or Type 1 scalable fonts, or any combination
of the two. First, let's concentrate on printing and previewing some
graphics.
In general, you will want to follow this procedure any time a LaTeX
source document has the statement
\includepackage{graphics}
in the document preamble. This statement tells LaTeX to include the
text of the graphics.sty package in the source document. There are
other commands to perform graphics operations, and the statements in
plain-TeX documents may not clue you in whether you need to use
dvips(1). The difference will be apparent in the output, though, when
the document is printed with missing figures and other graphics.
So, for now, we'll concentrate on printing documents which use the
LaTeX graphics.sty package. You might want to take a look at the
original TeX input. It isn't included in the teTeX distribution, but
it is available at
~CTAN/macros/latex/packages/graphics/grfguide.tex.
What the teTeX distribution does include is the .dvi output file, and
it is already TeXed for you. There is a reason for this, and it has
to do with the necessity of including Type 1 fonts in the output in
order for the document to print properly. If you want to LaTeX
grfguide.tex, see the next section. For now, however, we'll work on
getting usable output using dvips(1).
The file grfguide.dvi is located in the directory
texmf/doc/latex/graphics
The first step in outputting grfguide.dvi is to translate it to
PostScript. The program dvips(1) is used for this. It does just
exactly what its name implies. There are many options available for
invoking dvips(1), but the simplest (nearly) form is
dvips -f -r <grfguide.dvi >grfguide.ps
The -f command switch tells dvips(1) to operate as a filter, reading
from standard input and writing to standard output. dvips(1) output
can be configured so its output defaults to lpr(1). (Mine does, which
allows me to print directly from dvips(1).) Post processors like
Ghostscript and printing filters like APSFILTER (see section ``''
name="APSFILTER"), can be configured for your own needs. If you need
to feed the output manually to a post-processor, the -f option is gen-
erally the first you should include in the dvips(1) command line.
This form also seems to be easier to use in shell scripts.
If you can print PostScript directly to your printer via lpr(1), you
can simply type
dvips -r grfguide.dvi
The -r option tells dvips to output the pages in reverse order so they
stack correctly when they exit a printer. Use it or not, as appropri-
ate for your output device.
Depending on whether you still have the fonts that dvilj2(1) generated
from the last document, dvips(1) and metafont may or may not need to
create new fonts needed by grfguide.dvi. Eventually, though, dvips(1)
will output a list of the pages translated to PostScript, and you will
have your PostScript output ready to be rendered on whatever output
device you have available.
If you're lucky (and rich), then you have a PostScript-capable printer
already and will be able to print grfguide.ps directly. You can
either spool the output to the printer using lpr(1). If for some
reason your printer software doesn't work right with PostScript files,
you can, in a pinch, simply dump the file to printer, with
cat grfguide.ps >/dev/lp0
or whichever port your printer is attached to, though this is not rec-
ommended for everyday use.
If you want or need to invoke Ghostscript manually, this is the
standard procedure for its operation. The first thing you want to do
is invoke Ghostscript to view its command line arguments, like this:
gs -help | less
You'll see a list of supported output devices and sundry other com-
mands. Pick the output device which most nearly matches your printer.
On Chanel3, because I generally produce black-and-white text, I use
the cdjmono driver, which drives a color Deskjet in monochrome (black
and white) mode.
The command line I would use is:
gs -dNOPAUSE -sDEVICE=cdjmono -sOutputFile=/tmp/gs.out grfguide.ps -c quit
This will produce my HP-compatible output in the /tmp directory. It's
a good idea to use a directory like /tmp, because gs(1) can be partic-
ular about access permissions, and you can't (and shouldn't) always
count on being logged in as root to perform these steps. Now you can
print the file:
lpr /tmp/gs.out
Obviously, this can all go into a shell script. On my system, I have
two simple scripts written, pv and pr, which simply outputs the
PostScript file either to the display or the printer. Screen preview-
ing is possible without X, but it's far from ideal. So, it's defi-
nitely worth the effort to install XFree86, or TinyX (which is what I
did) to view the output on the screen.
The order of commands in a gs(1) command line is significant, because
some of the options tell Ghostscript to look for pieces of PostScript
code from its library.
The important thing to remember is that grfguide.dvi makes requests
for both Computer Modern bit mapped and Type 1 scaled fonts. If you
can mix scalable and bit mapped fonts in a document, you're well on
the way to becoming a TeXpert.
7. Using PostScript fonts.
It used to be that public domain, Type 1 fonts were much poorer
quality than Computer Modern bit mapped fonts. This situation has
improved in the last several years, though, but matching the fonts is
up to you. Having several different font systems on one machine can
seem redundant and an unnecessary waste of disk space. And the
Computer Modern fonts can seem, well, a little too formal to be
suitable for everyday use. It reminds me sometimes of bringing out
the good China to feed the dog. At least you don't need to spend a
bundle on professional quality fonts any longer.
One of the major improvements of LaTeX2e over its predecessor was the
inclusion of the New Font Selection Scheme. (It's now called PSNFSS.)
Formerly, TeX authors would specify fonts with commands like
\font=bodyroman = cmr10 scaled \magstep 1
which provides precision but requires the skills of a type designer
and mathematician to make good use of. Also, it's not very portable.
If another system didn't have the font cmr10 (this is TeX nomenclature
for Computer Modern Roman, 10 point, with the default medium stroke
weight), somebody would have to re-code the fonts specifications for
the entire document. PSNFSS, however, allows you specify fonts by
family (Computer Modern, URW Nimbus, Helvetica, Utopia, and so forth),
weight (light, medium, bold), orientation (upright or oblique), face
(Roman, Italic), and base point size. (See the section ``Characters
and type styles'' for a description of the commands to specify
typefaces.) Many fonts are packaged as families. For example, a
Roman-type font may come packaged with a sans serif font, like
Helvetica, and a monospaced font, like Courier. You, as the author of
a LaTeX document, can specify an entire font family with one command.
There are, as I said, several high-quality font sets available in the
public domain. One of them is Adobe Utopia. Another is Bitstream
Charter. Both are commercial quality fonts which have been donated to
the public domain.
These happen to be two of my favorites. If you look around one of the
CTAN sites, you will find these and other fonts archived there. There
are enough fonts around that you'll be able to design documents the
way you want them to look, and not just English text, either. TeX was
originally designed for mathematical typesetting, so there is a full
range of mathematical fonts available, as well as Cyrillic, Greek,
Kana, and other alphabets too numerous to mention.
The important thing to look for is files which have either the .pfa or
.pfb extension. They indicate that these are the scalable fonts
themselves, not simply the metrics files. Type 1 fonts use .pfm
metric files, as opposed to the .tfm metric files which bit mapped
fonts use. The two font sets I mentioned above are included in teTeX
distributions, as well as separately.
What I said above, concerning the ease of font selection under PSNFSS,
is true in this instance. If we want to use the Charter fonts in our
document instead of Computer Modern bit mapped, all that is necessary
is include the LaTeX statement
\renewcommand{\familydefault}{bch}
in the document preamble, where ``bch'' is the common designation for
Bitstream Charter. The Charter fonts reside in the directory
/usr/lib/teTeX/texmf/fonts/type1/bitstrea/charter
There you'll see the .pfb files of the Charter fonts: bchb8a.pfb for
Charter Bold, bchr8a.pfb for Charter Roman, bchbi8a.pfb for Charter
Bold Italic. The ``8a'' in the font names indicates the character
encoding. At this point you shouldn't need to worry much about them,
because the encodings mostly differ for 8-bit characters, which have
numeric values above 128 decimal. They mostly define accents and non-
English characters. The Type 1 font encodings generally work well for
Western alphabets because they conform to the ISO 8859 standards for
international character sets, so this is an added benefit of using
them.
To typeset a document which has Charter fonts selected, you would give
the command
pslatex document.tex
pslatex is a variant of teTeX's standard latex(1) command which
defines the directories where the Type 1 fonts are, as well as some
additional LaTeX code to load. You'll see the notice screen for psla-
tex followed by the status output of the TeX job itself. In a moment,
you'll have a .dvi file which includes the Charter font requests. You
can then print the file with dvips(1), and gs(1) if necessary.
Installing a Type 1 font set is not difficult, as long as you follow a
few basic steps. You should unpack the fonts in a subdirectory of the
/usr/lib/teTeX/texmf/fonts/type1 directory, where your other Type 1
fonts are located, and then run texhash to let the directory search
routines know that the fonts have been added. Then you need to add
the font descriptions to the file psfonts.map so dvips(1) knows
they're on the system. The format of the psfonts.map file is covered
in a couple different places in the references mentioned above.
Again, remember to run the texhash program to update the teTeX
directory database.
It is definitely an advantage to use the X Windows System with teTeX--
XFree86 under Linux -- because it allows for superior document
previewing. It's not required, but in general, anything that allows
for easier screen previewing is going to benefit your work, in terms
of the quality of the output. However, there is a tradeoff with speed
of editing, which is much quicker on character-mode displays. Having
an editor which is slower than molasses in Minnesota can definitely
hinder your work.
Anyway, whether or not you are able to view documents easily on-
screen, please recycle your paper, and use both sides of each sheet.
If possible, purchase recycled photocopy paper to print on. You don't
want your workplace to look like a branch office of a paper company.
Remember: Save a tree... kill an editor.
