1 Introduction
**************
This manual corresponds to version 2012 of Web2c, released in May 2012.
"Web2c" is the name of a TeX implementation, originally for Unix,
but now also running under DOS, Amiga, and other operating systems. By
"TeX implementation", we mean all of the standard programs developed by
the Stanford TeX project directed by Donald E. Knuth: Metafont,
DVItype, GFtoDVI, BibTeX, Tangle, etc., as well as TeX itself. Other
programs are also included: DVIcopy, written by Peter Breitenlohner,
MetaPost and its utilities (derived from Metafont), by John Hobby, etc.
General strategy: Web2c works, as its name implies, by translating
the WEB source in which TeX is written into C source code. Its output is
not self-contained, however; it makes extensive use of many macros and
functions in a library (the `web2c/lib' directory in the sources).
Therefore, it will not work without change on an arbitrary WEB program.
Availability: All of Web2c is freely available--"free" both in the
sense of no cost (free ice cream) and of having the source code to
modify and/or redistribute (free speech). *Note unixtex.ftp:
(kpathsea)unixtex.ftp, for the practical details of how to obtain Web2c.
Different parts of the Web2c distribution have different licensing
terms, however, reflecting the different circumstances of their
creation; consult each source file for exact details. The main
practical implication for redistributors of Web2c is that the
executables are covered by the GNU General Public License, and
therefore anyone who gets a binary distribution must also get the
sources, as explained by the terms of the GPL (*note Copying:
(kpathsea)Copying.). The GPL covers the Web2c executables, including
`tex', because the Free Software Foundation sponsored the initial
development of the Kpathsea library that Web2c uses. The basic source
files from Stanford, however, have their own copyright terms or are in
the public domain, and are not covered by the GPL.
History: Tomas Rokicki originated the TeX-to-C system in 1987,
working from the first change files for TeX under Unix, which were done
primarily by Howard Trickey and Pavel Curtis. Tim Morgan then took over
development and maintenance for a number of years; the name changed to
Web-to-C somewhere in there. In 1990, Karl Berry became the
maintainer. He made many changes to the original sources, and started
using the shorter name Web2c. In 1997, Olaf Weber took over. Dozens of
other people have contributed; their names are listed in the
`ChangeLog' files.
Other acknowledgements: The University of Massachusetts at Boston
(particularly Rick Martin and Bob Morris) provided computers and ftp
access to me for many years. Richard Stallman at the Free Software
Foundation employed me while I wrote the original path searching library
(for the GNU font utilities). (rms also gave us Emacs, GDB, and GCC,
without which I cannot imagine developing Web2c.) And, of course, TeX
would not exist in the first place without Donald E. Knuth.

2 Installation
**************
(A copy of this chapter is in the distribution file `web2c/INSTALL'.)
Installing Web2c is mostly the same as installing any other
Kpathsea-using program. Therefore, for the basic steps involved, see
*note Installation: (kpathsea)Installation. (A copy is in the file
`kpathsea/INSTALL'.)
One peculiarity to Web2c is that the source distribution comes in two
files: `web.tar.gz' and `web2c.tar.gz'. You must retrieve and unpack
them both. (We have two because the former archive contains the very
large and seldom-changing original WEB source files.) *Note
unixtex.ftp: (kpathsea)unixtex.ftp.
Another peculiarity is the MetaPost program. Although it has been
installed previously as `mp', as of Web2c 7.0 the installed name is now
`mpost', to avoid conflict with the `mp' program that does
prettyprinting. This approach was recommended by the MetaPost author,
John Hobby. If you as the TeX administrator wish to make it available
under its shorter name as well, you will have to set up a link or some
such yourself. And of course individual users can do the same.
For solutions to common installation problems and information on how
to report a bug, see the file `kpathsea/BUGS' (*note Bugs:
(kpathsea)Bugs.). See also the Web2c home page,
`http://www.tug.org/web2c'.
Points worth repeating:
* Before starting the standard compilation and installation you must
install the basic fonts, macros, and other library files. *Note
Installation: (kpathsea)Installation.
* If you do not wish to use the standard file locations, see *note
Changing search paths: (kpathsea)Changing search paths.
* Some Web2c features are enabled or disabled at `configure' time,
as described in the first section below.
* Menu:
* configure options:: Especially --with and --enable.
* Compile-time options:: Unusual -D's.
* Additional targets:: Breaking down the task.
* Triptrap:: Running the torture tests.
* Runtime options:: Array sizes and the like.
File: web2c.info, Node: configure options, Next: Compile-time options, Up: Installation
2.1 `configure' options
=======================
This section gives pointers to descriptions of the `--with' and
`--enable' `configure' arguments that Web2c accepts. Some are specific
to Web2c, others are generic to all Kpathsea-using programs.
For a list of all the options `configure' accepts, run `configure
--help'. The generic options are listed first, and the
package-specific options come last.
For a description of the generic options (which mainly allow you to
specify installation directories) and basic `configure' usage, see
*note Running `configure' scripts: (autoconf)Invoking configure, a copy
is in the file `kpathsea/CONFIGURE'.
`--disable-dump-share'
Do not make fmt/base/mem files sharable across different endian
architectures. *Note Hardware and memory dumps::.
`--without-maketexmf-default'
`--without-maketexpk-default'
`--without-maketextfm-default'
`--with-maketextex-default'
Enable or disable the dynamic generation programs. *Note mktex
configuration: (kpathsea)mktex configuration. The defaults are
the inverse of the options, i.e., everything is enabled except
`mktextex'.
`--enable-shared'
Build Kpathsea as a shared library. *Note Shared library:
(kpathsea)Shared library.
`--with-editor=CMD'
Change the default editor invoked by the `e' interactive command.
*Note Editor invocation::.
`--with-epsfwin'
`--with-hp2627win'
`--with-mftalkwin'
`--with-nextwin'
`--with-regiswin'
`--with-suntoolswin'
`--with-tektronixwin'
`--with-unitermwin'
`--with-x'
`--with-x-toolkit=KIT'
`--with-x11win'
`--with-x11'
Define Metafont graphics support; by default, no graphics support
is enabled. *Note Online Metafont graphics::.
`--x-includes=DIR'
`--x-libraries=DIR'
Define the locations of the X11 include files and libraries; by
default, `configure' does its best to guess). *Note Optional
Features: (autoconf)Optional Features. A copy is in
`kpathsea/CONFIGURE'.
File: web2c.info, Node: Compile-time options, Next: Additional targets, Prev: configure options, Up: Installation
2.2 Compile-time options
========================
In addition to the `configure' options listed in the previous section,
there are a few things that can be affected at compile-time with C
definitions, rather than with `configure'. Using any of these is
unusual.
To specify extra compiler flags (`-DNAME' in this case), the
simplest thing to do is:
make XCFLAGS="CCOPTIONS"
You can also set the `CFLAGS' environment variable before running
`configure'. *Note configure environment: (kpathsea)configure
environment.
Anyway, here are the possibilities:
`-DFIXPT'
`-DNO_MF_ASM'
Use the original WEB fixed-point routines for Metafont and MetaPost
arithmetic calculations regarding fractions. By default,
assembly-language routines are used on x86 hardware with GNU C
(unless `NO_MF_ASM' is defined), and floating-point routines are
used otherwise.
`-DIPC_DEBUG'
Report on various interprocess communication activities. *Note
IPC and TeX: IPC and TeX.
File: web2c.info, Node: Additional targets, Next: Triptrap, Prev: Compile-time options, Up: Installation
2.3 Additional targets
======================
Web2c has several Make targets besides the standard ones. You can
invoke these either in the top level directory of the source
distribution (the one containing `kpathsea/' and `web2c/'), or in the
`web2c/' directory.
`c-sources'
Make only the C files, translated from the Web sources, presumably
because you want to take them to a non-Unix machine.
`formats'
`install-formats'
Make or install all the memory dumps (*note Memory dumps::). By
default, the standard plain formats plus `latex.fmt' are made. You
can add other formats by redefining the `fmts', `bases', and
`mems' variables. See the top of `web2c/Makefile' for the
possibilities.
`fmts'
`install-fmts'
Make or install the TeX `.fmt' files. *Note Initial TeX::.
`bases'
`install-bases'
Make or install the Metafont `.base' files. *Note Initial
Metafont::.
`mems'
`install-mems'
Make or install the MetaPost `.mem' files. *Note Initial
MetaPost::.
`triptrap'
`trip'
`trap'
`mptrap'
To run the torture tests for TeX, Metafont, and MetaPost
(respectively). See the next section.
File: web2c.info, Node: Triptrap, Next: Runtime options, Prev: Additional targets, Up: Installation
2.4 Trip, trap, and mptrap: Torture tests
=========================================
To validate your TeX, Metafont, and MetaPost executables, run `make
triptrap'. This runs the trip, trap, and mptrap "torture tests". See
the files `triptrap/tripman.tex', `triptrap/trapman.tex', and
`triptrap/mptrap.readme' for detailed information and background on the
tests.
The differences between your executables' behavior and the standard
values will show up on your terminal. The usual differences (these are
all acceptable) are:
* string usage and table sizes;
* glue set ratios;
* `down4', `right4', and `y4' commands in DVItype output;
* dates and times.
Any other differences are trouble. The most common culprit in the past
has been compiler bugs, especially when optimizing. *Note TeX or
Metafont failing: (kpathsea)TeX or Metafont failing.
The files `trip.diffs', `mftrap.diffs', and `mptrap.diffs' in the
`triptrap' directory show the standard diffs against the original
output. If you diff your diffs against these files, you should come up
clean. For example
make trip >&mytrip.diffs
diff triptrap/trip.diffs mytrip.diffs
To run the tests separately, use the targets `trip', `trap', and
`mptrap'.
To run simple tests for all the programs as well as the torture
tests, run `make check'. You can compare the output to the distributed
file `tests/check.log' if you like.
File: web2c.info, Node: Runtime options, Prev: Triptrap, Up: Installation
2.5 Runtime options
===================
Besides the configure- and compile-time options described in the
previous sections, you can control a number of parameters (in
particular, array sizes) in the `texmf.cnf' runtime file read by
Kpathsea (*note Config files: (kpathsea)Config files.).
Rather than exhaustively listing them here, please see the last
section of the distributed `kpathsea/texmf.cnf'. Some of the more
interesting values:
`main_memory'
Total words of memory available, for TeX, Metafont, and MetaPost.
Must remake the format file after changing.
`extra_mem_bot'
Extra space for "large" TeX data structures: boxes, glue,
breakpoints, et al. If you use PiCTeX, you may well want to set
this.
`font_mem_size'
Words of font info available for TeX; this is approximately the
total size of all TFM files read.
`hash_extra'
Additional space for the hash table of control sequence names.
Approximately 10,000 control sequences can be stored in the main
hash table; if you have a large book with numerous
cross-references, this might not be enough, and thus you will want
to set `hash_extra'.
Of course, ideally all arrays would be dynamically expanded as
necessary, so the only limiting factor would be the amount of swap space
available. Unfortunately, implementing this is extremely difficult, as
the fixed size of arrays is assumed in many places throughout the source
code. These runtime limits are a practical compromise between the
compile-time limits in previous versions, and truly dynamic arrays. (On
the other hand, the Web2c BibTeX implementation does do dynamic
reallocation of some arrays.)
File: web2c.info, Node: Commonalities, Next: TeX, Prev: Installation, Up: Top
3 Commonalities
***************
Many aspects of the TeX system are the same among more than one
program, so we describe all those pieces together, here.
* Menu:
* Option conventions:: -- or -, = or ` ' for values.
* Common options:: --help --version --verbose, and TeX/MF/MP options.
* Path searching:: Features of the common path searching library.
* Output file location:: TEXMFOUTPUT allows output in places other than `.'.
* Three programs:: TeX, Metafont, and MetaPost have a lot in common.
File: web2c.info, Node: Option conventions, Next: Common options, Up: Commonalities
3.1 Option conventions
======================
To provide a clean and consistent behavior, we chose to have all these
programs use the GNU function `getopt_long_only' to parse command
lines. However, we do use in a restricted mode, where all the options
have to come before the rest of the arguments.
As a result, you can:
* use `-' or `--' to start an option name;
* use any unambiguous abbreviation for an option name;
* separate option names and values with either `=' or one or more
spaces;
* use filenames that would otherwise look like options by putting
them after an option `--'.
By convention, non-option arguments, if specified, generally define
the name of an input file, as documented for each program.
If a particular option with a value is given more than once, it is
the last value that counts.
For example, the following command line specifies the options `foo',
`bar', and `verbose'; gives the value `baz' to the `abc' option, and
the value `xyz' to the `quux' option; and specifies the filename
`-myfile-'.
-foo --bar -verb -abc=baz -quux karl --quux xyz -- -myfile-
File: web2c.info, Node: Common options, Next: Path searching, Prev: Option conventions, Up: Commonalities
3.2 Common options
==================
All of these programs accept the standard GNU `--help' and `--version'
options, and several programs accept `--verbose'. Rather than writing
identical descriptions for every program, they are described here.
`--help'
Print a usage message listing basic usage and all available
options to standard output, then exit successfully.
`--verbose'
Print progress reports to standard output.
`--version'
Print the version number to standard output, then exit
successfully.
TeX, Metafont, and MetaPost have a number of additional options in
common:
`-file-line-error'
`-no-file-line-error'
Change (or do not change) the way error messages are printed. The
alternate style looks like error messages from many compilers and
is easier to parse for some editors that invoke TeX. This option
used to be called `-file-line-error-style'.
`-fmt=DUMPNAME'
`-base=DUMPNAME'
`-mem=DUMPNAME'
Use DUMPNAME instead of the program name or a `%&' line to
determine the name of the memory dump file read (`fmt' for TeX,
`base' for Metafont, `mem' for MetaPost). *Note Memory dumps::.
Also sets the program name to DUMPNAME if no `-progname' option
was given.
`-halt-on-error'
Stop processing and exit when an error occurs, as opposed to the
normal process of trying to recover and continue.
`-ini'
Enable the "initial" form of the program (*note Initial and
virgin::). This is implicitly set if the program name is `initex'
resp. `inimf'.
`-interaction=STRING'
Set the interaction mode from the command line. The STRING must
be one of `batchmode', `nonstopmode', `scrollmode', or
`errorstopmode'.
`-jobname=STRING'
Set the job name to STRING, instead of deriving it from the name
of the input file.
`-kpathsea-debug=NUMBER'
Set path searching debugging flags according to the bits of NUMBER
(*note Debugging: (kpathsea)Debugging.). You can also specify
this in `KPATHSEA_DEBUG' environment variable (for all Web2c
programs). (The command line value overrides.) The most useful
value is `-1', to get all available output.
`-output-directory=DIRNAME'
Specify the directory DIRNAME to which output files are written.
Also look for input files in DIRNAME first, before looking along
the normal search path. *Note Output file location::.
`-parse-first-line'
`-no-parse-first-line'
Check or disable checking whether the first line of the main input
file starts with `%&', and parse it if it does. This line can be
used specify the format and/or a TCX file.
`-progname=STRING'
Set program (and memory dump) name to STRING. This may affect the
search paths and other values used (*note Config files:
(kpathsea)Config files.). Using this option is equivalent to
making a link named STRING to the binary and then invoking the
binary under that name. *Note Memory dumps::.
`-recorder'
Enable the filename recorder. This makes the program save a list
of the opened files into a file with (by default) extension
`.fls'. For Aleph, this option is always on, and the file has
extension `.ofl'.
Ordinarily, the `.fls' file is written to the same location as the
`.log' file, for example, respecting `-output-directory' if it is
given (*note Output file location::). However, if TeX processing
is done on the command line (or in response to the `**' prompt),
the `.fls' might be written to the current directory, or include
an integer (the current pid), as in `texput1234.fls'. You can use
`-jobname' to explicitly set the basename.
`-translate-file=TCXFILE'
Use TCXFILE to define which characters are printable and
translations between the internal and external character sets.
Moreover, TCXFILE can be explicitly declared in the first line of
the main input file `%& -translate-file=TCXFILE'. This is the
recommended method for portability reasons. *Note TCX files::.
`-8bit'
This option specifies that by default all characters should be
considered printable. If `-translate-file' was given as well,
then the TCX file may mark characters as non-printable.
File: web2c.info, Node: Path searching, Next: Output file location, Prev: Common options, Up: Commonalities
3.3 Path searching
==================
All of the Web2c programs, including TeX, which do path searching use
the Kpathsea routines to do so. The precise names of the environment
and configuration file variables which get searched for particular file
formatted are therefore documented in the Kpathsea manual (*note
Supported file formats: (kpathsea)Supported file formats.). Reading
`texmf.cnf' (*note Config files: (kpathsea)Config files.), invoking
`mktex...' scripts (*note mktex scripts: (kpathsea)mktex scripts.), and
so on are all handled by Kpathsea.
The programs which read fonts make use of another Kpathsea feature:
`texfonts.map', which allows arbitrary aliases for the actual names of
font files; for example, `Times-Roman' for `ptmr8r.tfm'. The
distributed (and installed by default) `texfonts.map' includes aliases
for many widely available PostScript fonts by their PostScript names.
File: web2c.info, Node: Output file location, Next: Three programs, Prev: Path searching, Up: Commonalities
3.4 Output file location
========================
All the programs generally follow the usual convention for output files.
Namely, they are placed in the directory current when the program is
run, regardless of any input file location; or, in a few cases, output
is to standard output.
For example, if you run `tex /tmp/foo', for example, the output will
be in `./foo.dvi' and `./foo.log', not `/tmp/foo.dvi' and
`/tmp/foo.log'.
You can use the `-output-directory' option to cause all output files
that would normally be written in the current directory to be written
in the specified directory instead. *Note Common options::.
If the current directory is not writable, and `-output-directory' is
not specified, the main programs (TeX, Metafont, MetaPost, and BibTeX)
make an exception: if the config file or environment variable value
`TEXMFOUTPUT' is set (it is not by default), output files are written
to the directory specified.
`TEXMFOUTPUT' is also checked for input files, as TeX often
generates files that need to be subsequently read; for input, no
suffixes (such as `.tex') are added by default and no exhaustive path
searching is done, the input name is simply checked as given.
File: web2c.info, Node: Three programs, Prev: Output file location, Up: Commonalities
3.5 Three programs: Metafont, MetaPost, and TeX
===============================================
TeX, Metafont, and MetaPost have a number of features in common.
Besides the ones here, the common command-line options are described in
the previous section. The configuration file options that let you
control some array sizes and other features are described in *note
Runtime options::.
* Menu:
* Initial and virgin:: Making memory dumps vs. production runs.
* Memory dumps:: .fmt/.base files for fast startup.
* Editor invocation:: The `e' response at errors.
* \input filenames:: ~ and $ expansion in TeX/MF/MP.
File: web2c.info, Node: Initial and virgin, Next: Memory dumps, Up: Three programs
3.5.1 Initial and virgin
------------------------
The TeX and Metafont programs each have two main variants, called
"initial" and "virgin". MetaPost no longer makes this distinction.
The initial form is enabled if:
1. the `-ini' option was specified; or
2. the program name is `initex' resp. `inimf'; or
3. the first line of the main input file is `%&ini';
otherwise, the virgin form is used.
The "virgin" form is the one generally invoked for production use.
The first thing it does is read a memory dump (*note Determining the
memory dump to use::), and then proceeds on with the main job.
The "initial" form is generally used only to create memory dumps
(see the next section). It starts up more slowly than the virgin form,
because it must do lengthy initializations that are encapsulated in the
memory dump file.
File: web2c.info, Node: Memory dumps, Next: Editor invocation, Prev: Initial and virgin, Up: Three programs
3.5.2 Memory dumps
------------------
In typical use, TeX and Metafont require a large number of macros to be
predefined; therefore, they support "memory dump" files, which can be
read much more efficiently than ordinary source code.
* Menu:
* Creating memory dumps::
* Determining the memory dump to use::
* Hardware and memory dumps::
File: web2c.info, Node: Creating memory dumps, Next: Determining the memory dump to use, Up: Memory dumps
3.5.2.1 Creating memory dumps
.............................
The programs all create memory dumps in slightly idiosyncratic (thought
substantially similar) way, so we describe the details in separate
sections (references below). The basic idea is to run the initial
version of the program (*note Initial and virgin::), read the source
file to define the macros, and then execute the `\dump' primitive.
Also, each program uses a different filename extension for its memory
dumps, since although they are completely analogous they are not
interchangeable (TeX cannot read a Metafont memory dump, for example).
Here is a list of filename extensions with references to examples of
creating memory dumps:
TeX
(`.fmt') *Note Initial TeX: Initial TeX.
Metafont
(`.base') *Note Initial Metafont::.
When making memory dumps, the programs read environment variables and
configuration files for path searching and other values as usual. If
you are making a new installation and have environment variables
pointing to an old one, for example, you will probably run into
difficulties.
File: web2c.info, Node: Determining the memory dump to use, Next: Hardware and memory dumps, Prev: Creating memory dumps, Up: Memory dumps
3.5.2.2 Determining the memory dump to use
..........................................
The virgin form (*note Initial and virgin::) of each program always
reads a memory dump before processing normal source input. All three
programs determine the memory dump to use in the same way:
1. If the first non-option command-line argument begins with `&', the
program uses the remainder of that argument as the memory dump
name. For example, running `tex \&super' reads `super.fmt'. (The
backslash protects the `&' against interpretation by the shell.)
2. If the `-fmt' resp. `-base' option is specified, its value is used.
3. If the `-progname' option is specified, its value is used.
4. If the first line of the main input file (which must be specified
on the command line, not in response to `**') is `%&DUMP', and
DUMP is an existing memory dump of the appropriate type, DUMP is
used.
The first line of the main input file can also specify which
character translation file is to be used:
`%&-translate-file=TCXFILE' (*note TCX files::).
These two roles can be combined: `%&DUMP -translate-file=TCXFILE'.
If this is done, the name of the dump must be given first.
5. Otherwise, the program uses the program invocation name, most
commonly `tex' resp. `mf'. For example, if `latex' is a link to
`tex', and the user runs `latex foo', `latex.fmt' will be used.
File: web2c.info, Node: Hardware and memory dumps, Prev: Determining the memory dump to use, Up: Memory dumps
3.5.2.3 Hardware and memory dumps
.................................
By default, memory dump files are generally sharable between
architectures of different types; specifically, on machines of different
endianness (*note Byte order: (libc)Byte order.). (This is a feature
of the Web2c implementation, and is not true of all TeX
implementations.) If you specify `--disable-dump-share' to
`configure', however, memory dumps will be endian-dependent.
The reason to do this is speed. To achieve endian-independence, the
reading of memory dumps on LittleEndian architectures, such as PC's and
DEC architectures, is somewhat slowed (all the multibyte values have to
be swapped). Usually, this is not noticeable, and the advantage of
being able to share memory dumps across all platforms at a site far
outweighs the speed loss. But if you're installing Web2c for use on
LittleEndian machines only, perhaps on a PC being used only by you, you
may wish to get maximum speed.
TeXnically, even without `--disable-dump-share', sharing of `.fmt'
files cannot be guaranteed to work. Floating-point values are always
written in native format, and hence will generally not be readable
across platforms. Fortunately, TeX uses floating point only to
represent glue ratios, and all common formats (plain, LaTeX, AMSTeX,
...) do not do any glue setting at `.fmt'-creation time. Metafont does
not use floating point in any dumped value at all.
Incidentally, different memory dump files will never compare equal
byte-for-byte, because the program always dumps the current date and
time. So don't be alarmed by just a few bytes difference.
If you don't know what endianness your machine is, and you're
curious, here is a little C program to tell you. (The `configure' script
contains a similar program.) This is from the book `C: A Reference
Manual', by Samuel P. Harbison and Guy L. Steele Jr. (*note
References::).
main ()
{
/* Are we little or big endian? From Harbison&Steele. */
union
{
long l;
char c[sizeof (long)];
} u;
u.l = 1;
if (u.c[0] == 1)
printf ("LittleEndian\n");
else if (u.c[sizeof (long) - 1] == 1)
printf ("BigEndian\n");
else
printf ("unknownEndian");
exit (u.c[sizeof (long) - 1] == 1);
}
File: web2c.info, Node: Editor invocation, Next: \input filenames, Prev: Memory dumps, Up: Three programs
3.5.3 Editor invocation
-----------------------
TeX, Metafont, and MetaPost all (by default) stop and ask for user
intervention at an error. If the input came from a file, and the user
responds with `e' or `E', the program invokes an editor.
Specifying `--with-editor=CMD' to `configure' sets the default
editor command string to CMD. The environment variables/configuration
values `TEXEDIT', `MFEDIT', and `MPEDIT' (respectively) override this.
If `--with-editor' is not specified, the default is `vi +%d %s' on
Unix, and an invocation of the TeXworks editor on Windows. (See
`texmf.cnf' for the precise values.)
In this string, `%d' is replaced by the line number of the error,
and `%s' is replaced by the name of the current input file.
File: web2c.info, Node: \input filenames, Prev: Editor invocation, Up: Three programs
3.5.4 `\input' filenames
------------------------
TeX, Metafont, and MetaPost source programs can all read other source
files with the `\input' (TeX) and `input' (MF and MP) primitives:
\input NAME % in TeX
The file NAME can always be terminated with whitespace; for Metafont
and MetaPost, the statement terminator `;' also works. (LaTeX and
other macro packages provide other interfaces to `\input' that allow
different notation; here we are concerned only with the primitive
operation.)
As of Web2c version 7.5.3, double-quote characters can be used to
include spaces or other special cases. In typical use, the `"'
characters surround the entire filename:
\input "filename with spaces"
Technically, the quote characters can be used inside the name, and
can enclose any characters, as in:
\input filename" "with" "spaces
One more point. In LaTeX, the quotes are needed inside the braces,
thus
\input{a b} % fails
\input{"a b"} % ok
This quoting mechanism comes into play _after_ TeX has tokenized and
expanded the input. So, multiple spaces and tabs may be seen as a
single space, active characters such as `~' are expanded first, and so
on. (See below.)
On the other hand, various C library routines and Unix itself use
the null byte (character code zero, ASCII NUL) to terminate strings. So
filenames in Web2c cannot contain nulls, even though TeX itself does
not treat NUL specially. In addition, some older Unix variants do not
allow eight-bit characters (codes 128-255) in filenames.
For maximal portability of your document across systems, use only the
characters `a'-`z', `0'-`9', and `.', and restrict your filenames to at
most eight characters (not including the extension), and at most a
three-character extension. Do not use anything but simple filenames,
since directory separators vary among systems; instead, add the
necessary directories to the appropriate search path.
Finally, the present Web2c implementation does `~' and `$' expansion
on NAME, unlike Knuth's original implementation and older versions of
Web2c. Thus:
\input ~jsmith/$foo.bar
will dereference the environment variable or Kpathsea config file
value `foo' and read that file extended with `.bar' in user `jsmith''s
home directory. You can also use braces, as in `${foo}bar', if you
want to follow the variable name with a letter, numeral, or `_'.
(So another way to get a program to read a filename containing
whitespace is to define an environment variable and dereference it.)
In all the common TeX formats (plain TeX, LaTeX, AMSTeX), the
characters `~' and `$' have special category codes, so to actually use
these in a document you have to change their catcodes or use `\string'.
(The result is unportable anyway, see the suggestions above.) The
place where they are most likely to be useful is when typing
interactively.

4 TeX: Typesetting
******************
TeX is a typesetting system: it was especially designed to handle
complex mathematics, as well as most ordinary text typesetting.
TeX is a batch language, like C or Pascal, and not an interactive
"word processor": you compile a TeX input file into a corresponding
device-independent (DVI) file (and then translate the DVI file to the
commands for a particular output device). This approach has both
considerable disadvantages and considerable advantages. For a complete
description of the TeX language, see `The TeXbook' (*note
References::). Many other books on TeX, introductory and otherwise,
are available.

File: web2c.info, Node: tex invocation, Next: Initial TeX, Up: TeX
4.1 `tex' invocation
====================
TeX (usually invoked as `tex') formats the given text and commands, and
outputs a corresponding device-independent representation of the
typeset document. This section merely describes the options available
in the Web2c implementation. For a complete description of the TeX
typesetting language, see `The TeXbook' (*note References::).
TeX, Metafont, and MetaPost process the command line (described
here) and determine their memory dump (fmt) file in the same way (*note
Memory dumps::). Synopses:
tex [OPTION]... [TEXNAME[.tex]] [TEX-COMMANDS]
tex [OPTION]... \FIRST-LINE
tex [OPTION]... &FMT ARGS
TeX searches the usual places for the main input file TEXNAME (*note
Supported file formats: (kpathsea)Supported file formats.), extending
TEXNAME with `.tex' if necessary. To see all the relevant paths, set
the environment variable `KPATHSEA_DEBUG' to `-1' before running the
program.
After TEXNAME is read, TeX processes any remaining TEX-COMMANDS on
the command line as regular TeX input. Also, if the first non-option
argument begins with a TeX escape character (usually `\'), TeX
processes all non-option command-line arguments as a line of regular
TeX input.
If no arguments or options are specified, TeX prompts for an input
file name with `**'.
TeX writes the main DVI output to the file `BASETEXNAME.dvi', where
BASETEXNAME is the basename of TEXNAME, or `texput' if no input file
was specified. A DVI file is a device-independent binary
representation of your TeX document. The idea is that after running
TeX, you translate the DVI file using a separate program to the
commands for a particular output device, such as a PostScript printer
(*note Introduction: (dvips)Top.) or an X Window System display (see
xdvi(1)).
TeX also reads TFM files for any fonts you load in your document with
the `\font' primitive. By default, it runs an external program named
`mktextfm' to create any nonexistent TFM files. You can disable this
at configure-time or runtime (*note mktex configuration:
(kpathsea)mktex configuration.). This is enabled mostly for the sake
of the EC fonts, which can be generated at any size.
TeX can write output files, via the `\openout' primitive; this opens
a security hole vulnerable to Trojan horse attack: an unwitting user
could run a TeX program that overwrites, say, `~/.rhosts'. (MetaPost
has a `write' primitive with similar implications). To alleviate this
and similar problems the functions `kpathsea_out_name_ok' and
`kpathsea_in_name_ok' from the Kpathse library (*note Calling sequence:
(kpathsea)Calling sequence.) are used to determine if a given filename
is acceptable to be opened for output or input, depending on the
setting of the configuration variables `openout_any' and `openin_any':
`a' (for "any", the default for `openin_any'), `r' (for "restricted"),
or `p' (for "paranoid", the default for `openout_any').
In any case, all `\openout' filenames are recorded in the log file,
except those opened on the first line of input, which is processed when
the log file has not yet been opened.
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-enc'
`-[no]-file-line-error'
`-fmt=FMTNAME'
`-halt-on-error'
`-ini'
`-interaction=STRING'
`-ipc'
`-ipc-start'
`-jobname=STRING'
`-kpathsea-debug=NUMBER'
`-[no]parse-first-line'
`-output-directory'
`-progname=STRING'
`-recorder'
`-translate-file=TCXFILE'
`-8bit'
These options are common to TeX, Metafont, and MetaPost. *Note
Common options::.
`-enc'
Enable encTeX extensions, such as `\mubyte'. This can be used to
support Unicode UTF-8 input encoding. See
`http://www.olsak.net/enctex.html'.
`-ipc'
`-ipc-start'
With either option, TeX writes its DVI output to a socket as well
as to the usual `.dvi' file. With `-ipc-start', TeX also opens a
server program at the other end to read the output. *Note IPC and
TeX: IPC and TeX.
These options are available only if the `--enable-ipc' option was
specified to `configure' during installation of Web2c.
`-mktex=FILETYPE'
`-no-mktex=FILETYPE'
Turn on or off the `mktex' script associated with FILETYPE. For
TeX proper, FILETYPE can only be `tex' and `tfm', but for pdfTeX
and luaTeX, it can also be `pk'.
`-mltex'
If we are `INITEX' (*note Initial and virgin::), enable MLTeX
extensions such as `\charsubdef'. Implicitly set if the program
name is `mltex'. *Note MLTeX: MLTeX.
`-output-comment=STRING'
Use STRING as the DVI file comment. Ordinarily, this comment
records the date and time of the TeX run, but if you are doing
regression testing, you may not want the DVI file to have this
spurious difference. This is also taken from the environment
variable and config file value `output_comment'.
`-shell-escape'
`-no-shell-escape'
`-shell-restricted'
Enable, or disable, or enable with restrictions the
`\write18{SHELL-COMMAND}' feature for external executing shell
commands. *Note Shell escapes::.
`-enable-write18'
`-disable-write18'
Synonyms for `-shell-escape' and `-no-shell-escape', for
compatibility with MiKTeX. (MiKTeX also accepts both pairs of
options.) *Note Shell escapes::.
`-src-specials'
`-src-specials=STRING'
This option makes TeX output specific source information using
`\special' commands in the DVI file. These `\special' track the
current file name and line number.
Using the first form of this option, the `\special' commands are
inserted automatically.
In the second form of the option, STRING is a comma separated list
of the following values: `cr', `display', `hbox', `math', `par',
`parend', `vbox'. You can use this list to specify where you want
TeX to output such commands. For example, `-src-specials=cr,math'
will output source information every line and every math formula.
These commands can be used with the appropriate DVI viewer and
text editor to switch from the current position in the editor to
the same position in the viewer and back from the viewer to the
editor.
This option works by inserting `\special' commands into the token
stream, and thus in principle these additional tokens can be
recovered or seen by the tricky-enough macros. If you run across
a case, let us know, because this counts as a bug. However, such
bugs are very hard to fix, requiring significant changes to TeX,
so please don't count on it.
Redefining `\special' will not affect the functioning of this
option. The commands inserted into the token stream are
hard-coded to always use the `\special' primitive.
TeX does not pass the trip test when this option is enabled.

4.2 Initial TeX
===============
The "initial" form of TeX is invoked by `tex -ini'. It does lengthy
initializations avoided by the "virgin" (`vir') form, so as to be
capable of dumping `.fmt' files (*note Memory dumps::). For a detailed
comparison of virgin and initial forms, *note Initial and virgin::. In
past releases, a separate program `initex' was installed to invoke the
initial form, but this is no longer the case.
For a list of options and other information, *note tex invocation::.
Unlike Metafont and MetaPost, many format files are commonly used
with TeX. The standard one implementing the features described in the
`TeXbook' is `plain.fmt', also known as `tex.fmt' (again, *note Memory
dumps::). It is created by default during installation, but you can
also do so by hand if necessary (e.g., if an update to `plain.tex' is
issued):
tex -ini '\input plain \dump'
(The quotes prevent interpretation of the backslashes from the
shell.) Then install the resulting `plain.fmt' in `$(fmtdir)'
(`/usr/local/share/texmf/web2c' by default), and link `tex.fmt' to it.
The necessary invocation for generating a format file differs for
each format, so instructions that come with the format should explain.
The top-level `web2c' Makefile has targets for making most common
formats: plain latex amstex texinfo eplain. *Note Formats::, for more
details on TeX formats.
File: web2c.info, Node: Formats, Next: Languages and hyphenation, Prev: Initial TeX, Up: TeX
4.3 Formats
===========
TeX "formats" are large collections of macros, often dumped into a
`.fmt' file (*note Memory dumps::) by `tex -ini' (*note Initial TeX::).
A number of formats are in reasonably widespread use, and the Web2c
Makefile has targets to make the versions current at the time of
release. You can change which formats are automatically built by
setting the `fmts' Make variable; by default, only the `plain' and
`latex' formats are made.
You can get the latest versions of most of these formats from the
CTAN archives in subdirectories of `CTAN:/macros' (for CTAN info, *note
unixtex.ftp: (kpathsea)unixtex.ftp.). The archive
`ftp://ftp.tug.org/tex/lib.tar.gz' (also available from CTAN) contains
most of these formats (although perhaps not the absolute latest
version), among other things.
latex
The most widely used format. The current release is named `LaTeX
2e'; new versions are released approximately every six months, with
patches issued as needed. The old release was called `LaTeX 2.09',
and is no longer maintained or supported. LaTeX attempts to
provide generic markup instructions, such as "emphasize", instead
of specific typesetting instructions, such as "use the 10pt
Computer Modern italic font". The LaTeX home page:
`http://www.latex-project.org'.
context
ConTeXt is an independent macro package which has a basic document
structuring approach similar to LaTeX. It also supports creating
interactive PDF files and has integrated MetaPost support, among
many other interesting features. The ConTeXt home page:
`http://www.pragma-ade.com'.
amstex
The official typesetting system of the American Mathematical
Society. Like LaTeX, it encourages generic markup commands. The
AMS also provides many LaTeX package for authors who prefer LaTeX.
Taken together, they are used to produce nearly all AMS
publications, e.g., `Mathematical Reviews'. The AMSTeX home page:
`http://www.ams.org/tex'.
texinfo
The documentation system developed and maintained by the Free
Software Foundation for their software manuals. It can be
automatically converted into plain text, a machine-readable
on-line format called `info', HTML, etc. The Texinfo home page:
`http://www.gnu.org/software/texinfo'.
eplain
The "expanded plain" format provides various common features (e.g.,
symbolic cross-referencing, tables of contents, indexing, citations
using BibTeX), for those authors who prefer to handle their own
high-level formatting. The Eplain home page:
`http://www.tug.org/eplain'.
slitex
An obsolete LaTeX 2.09 format for making slides. It is replaced by
the `slides' document class, along with the `beamer', `texpower',
and other packages.

4.4.1 MLTeX: Multi-lingual TeX
------------------------------
Multi-lingual TeX (`mltex') is an extension of TeX originally written
by Michael Ferguson and now updated and maintained by Bernd Raichle.
It allows the use of non-existing glyphs in a font by declaring glyph
substitutions. These are restricted to substitutions of an accented
character glyph, which need not be defined in the current font, by its
appropriate `\accent' construction using a base and accent character
glyph, which do have to exist in the current font. This substitution
is automatically done behind the scenes, if necessary, and thus MLTeX
additionally supports hyphenation of words containing an accented
character glyph for fonts missing this glyph (e.g., Computer Modern).
Standard TeX suppresses hyphenation in this case.
MLTeX works at `.fmt'-creation time: the basic idea is to specify
the `-mltex' option to TeX when you `\dump' a format. Then, when you
subsequently invoke TeX and read that `.fmt' file, the MLTeX features
described below will be enabled.
Generally, you use special macro files to create an MLTeX `.fmt'
file.
The sections below describe the two new primitives that MLTeX
defines. Aside from these, MLTeX is completely compatible with
standard TeX.
* Menu:
* \charsubdef:: Character substitution definitions.
* \tracingcharsubdef:: Tracing substitutions.
File: web2c.info, Node: \charsubdef, Next: \tracingcharsubdef, Up: MLTeX
4.4.1.1 `\charsubdef': Character substitutions
..............................................
The most important primitive MLTeX adds is `\charsubdef', used in a way
reminiscent of `\chardef':
\charsubdef COMPOSITE [=] ACCENT BASE
Each of COMPOSITE, ACCENT, and BASE are font glyph numbers,
expressed in the usual TeX syntax: `\e symbolically, '145 for octal,
"65 for hex, 101 for decimal.
MLTeX's `\charsubdef' declares how to construct an accented
character glyph (not necessarily existing in the current font) using two
character glyphs (that do exist). Thus it defines whether a character
glyph code, either typed as a single character or using the `\char'
primitive, will be mapped to a font glyph or to an `\accent' glyph
construction.
For example, if you assume glyph code 138 (decimal) for an
e-circumflex and you are using the Computer Modern fonts, which have
the circumflex accent in position 18 and lowercase `e' in the usual
ASCII position 101 decimal, you would use `\charsubdef' as follows:
\charsubdef 138 = 18 101
For the plain TeX format to make use of this substitution, you have
to redefine the circumflex accent macro `\^' in such a way that if its
argument is character `e' the expansion `\char138 ' is used instead of
`\accent18 e'. Similar `\charsubdef' declaration and macro
redefinitions have to be done for all other accented characters.
To disable a previous `\charsubdef C', redefine C as a pair of
zeros. For example:
\charsubdef '321 = 0 0 % disable N tilde
(Octal '321 is the ISO Latin-1 value for the Spanish N tilde.)
`\charsubdef' commands should only be given once. Although in
principle you can use `\charsubdef' at any time, the result is
unspecified. If `\charsubdef' declarations are changed, usually either
incorrect character dimensions will be used or MLTeX will output
missing character warnings. (The substitution of a `\charsubdef' is
used by TeX when appending the character node to the current horizontal
list, to compute the width of a horizontal box when the box gets
packed, and when building the `\accent' construction at
`\shipout'-time. In summary, the substitution is accessed often, so
changing it is not desirable, nor generally useful.)
File: web2c.info, Node: \tracingcharsubdef, Prev: \charsubdef, Up: MLTeX
4.4.1.2 `\tracingcharsubdef': Substitution diagnostics
......................................................
To help diagnose problems with `\charsubdef', MLTeX provides a new
primitive parameter, `\tracingcharsubdef'. If positive, every use of
`\charsubdef' will be reported. This can help track down when a
character is redefined.
In addition, if the TeX parameter `\tracinglostchars' is 100 or
more, the character substitutions actually performed at `\shipout'-time
will be recorded.

-------------------------------------------
Patgen creates hyphenation patterns from dictionary files for use with

Each argument is a filename. No path searching is done. The output is

In addition, Patgen prompts interactively for other values.

Frank Liang (*note References::), and also the `patgen.web' source file.
The only options are `-help' and `-version' (*note Common options::).
File: web2c.info, Node: TCX files, Prev: patgen invocation, Up: Languages and hyphenation
4.4.2 TCX files: Character translations
---------------------------------------
TCX (TeX character translation) files help TeX support direct input of
8-bit international characters if fonts containing those characters are
being used. Specifically, they map an input (keyboard) character code
to the internal TeX character code (a superset of ASCII).
Of the various proposals for handling more than one input encoding,
TCX files were chosen because they follow Knuth's original ideas for
the use of the `xchr' and `xord' tables. He ventured that these would
be changed in the WEB source in order to adjust the actual version to a
given environment. It turns out, however, that recompiling the WEB
sources is not as simple a task as Knuth may have imagined; therefore,
TCX files, providing the possibility of changing of the conversion
tables on on-the-fly, have been implemented instead.
This approach limits the portability of TeX documents, as some
implementations do not support it (or use a different method for
input-internal reencoding). It may also be problematic to determine
the encoding to use for a TeX document of unknown provenance; in the
worst case, failure to do so correctly may result in subtle errors in
the typeset output. But we feel the benefits outweigh these
disadvantages.
This is entirely independent of the MLTeX extension (*note MLTeX::):
whereas a TCX file defines how an input keyboard character is mapped to
TeX's internal code, MLTeX defines substitutions for a non-existing
character glyph in a font with a `\accent' construction made out of two
separate character glyphs. TCX files involve no new primitives; it is
not possible to specify that an input (keyboard) character maps to more
than one character.
Information on specifying TCX files:
* The best way to specify a TCX file is to list it explicitly in the
first line of the main document:
%& -translate-file=TCXFILE
* You can also specify a TCX file to be used on a particular TeX run
with the command-line option `-translate-file=TCXFILE'.
* TCX files are searched for along the `WEB2C' path.
* Initial TeX (*note Initial TeX: Initial TeX.) ignores TCX files.
The Web2c distribution comes with a number of TCX files. Two
important ones are `il1-t1.tcx' and `il2-t1.tcx', which support ISO
Latin 1 and ISO Latin 2, respectively, with Cork-encoded fonts (a.k.a.
the LaTeX T1 encoding). TCX files for Czech, Polish, and Slovak are
also provided.
One other notable TCX file is `empty.tcx', which is, well, empty.
Its purpose is to reset Web2C's behavior to the default (only visible
ASCII being printable, as described below) when a format was dumped
with another TCX being active--which is in fact the case for everything
but plain TeX in the TeX Live and other distributions. Thus:
latex somefile8.tex
=> terminal etc. output with 8-bit chars
latex --translate-file=empty.tcx somefile8.tex
=> terminal etc. output with ^^ notation
Syntax of TCX files:
1. Line-oriented. Blank lines are ignored.
2. Whitespace is ignored except as a separator.
3. Comments start with `%' and continue to the end of the line.
4. Otherwise, a line consists of one or two character codes,
optionally followed by 0 or 1. The last number indicates whether
DEST is considered printable.
SRC [DEST [PRNT]]
5. Each character code may be specified in octal with a leading `0',
hexadecimal with a leading `0x', or decimal otherwise. Values must
be between 0 and 255, inclusive (decimal).
6. If the DEST code is not specified, it is taken to be the same as
SRC.
7. If the same SRC code is specified more than once, it is the last
definition that counts.
Finally, here's what happens: when TeX sees an input character with
code SRC, it 1) changes SRC to DEST; and 2) makes the DEST code
"printable", i.e., printed as-is in diagnostics and the log file rather
than in `^^' notation.
By default, no characters are translated, and character codes
between 32 and 126 inclusive (decimal) are printable.
Specifying translations for the printable ASCII characters (codes
32-127) will yield unpredictable results. Additionally you shouldn't
make the following characters printable: `^^I' (TAB), `^^J' (line
feed), `^^M' (carriage return), and `^^?' (delete), since TeX uses them
in various ways.
Thus, the idea is to specify the input (keyboard) character code for
SRC, and the output (font) character code for DEST.
By default, only the printable ASCII characters are considered
printable by TeX. If you specify the `-8bit' option, all characters are
considered printable by default. If you specify both the `-8bit'
option and a TCX file, then the TCX can set specific characters to be
non-printable.
Both the specified TCX encoding and whether characters are printable
are saved in the dump files (like `tex.fmt'). So by giving these
options in combination with `-ini', you control the defaults seen by
anyone who uses the resulting dump file.
When loading a dump, if the `-8bit' option was given, then all
characters become printable by default.
When loading a dump, if a TCX file was specified, then the TCX data
from the dump is ignored and the data from the file used instead.
File: web2c.info, Node: Shell escapes, Next: IPC and TeX, Prev: Languages and hyphenation, Up: TeX
4.5 Shell escapes
=================
TeX can execute "shell escapes", that is, arbitrary shell commands.
Although tremendously useful, this also has obvious security
implications. Therefore, as of TeX Live 2009, a "restricted" mode for
shell escapes is the default mode of operation, which allows executing
only certain commands, as specified in the `texmf.cnf' configuration
file.
* Unrestricted shell escapes are allowed if the option
`--shell-escape' is specified, or if the environment variable or
config file value `shell_escape' is set to `t' or `y' and `1'.
* Restricted shell escapes are allowed if `shell_escape' is set to
`p'. This is the default.
* Shell escapes are completely disabled if `--no-shell-escape' is
specified, or if `shell_escape' is set to anything else.
When enabled, the TeX construct to execute a system command is
`\write18{SHELL-COMMAND}'; for example:
\write18{echo "hello, world"}
From TeX's point of view, this is a normal `\write' command, and is
therefore subject to the usual TeX expansions. Also, the system call
either happens during the `\output' routine or right away, according to
the absence or presence of the `\immediate' prefix, as usual for
`\write'.
The SHELL-COMMAND string is passed to the command shell (via the C
library function `system'). The output of SHELL-COMMAND is not
diverted anywhere, so it will not appear in the log file, or anywhere
but the terminal output. The exit status of the system call is also
not available to TeX.
In unrestricted mode, the argument is simply passed straight to
`system' unaltered.
In restricted mode, ASCII double quote characters (") should always
be used in the argument to `\write18' where quoting of arguments is
needed, as in the example above. This is to achieve some measure of
system independence. On Unix systems, these are replaced with single
quote (') characters to avoid insecure further expansion. Care is also
taken on Windows to avoid additional expansions (from, e.g., `...`).
Mismatched quotation marks in the command string result in a diagnostic
message in the log file; no execution is performed.
After quotation processing, if the first word (delimited by a space
or tab) of the command is in the list specified by the
`shell_escape_commands' configuration value, the command is executed.
Otherwise it is not. In any case, a message is written to the log file.
The `shell_escape_commands' value is a comma-separated list of
words. Whitespace is significant, and typically should not be present.
The default definition looks like this, but with more commands included:
shell_escape_commands = bibtex,dvips,epstopdf,...,tex
pdfTeX and luaTeX support reading (via `\input' and `\openin') and
writing (via `\openout') from pipes if the first character is `|'. The
following command is then treated exactly the same as the argument to
`\write18'. In these engines, the primitive variable `\pdfshellescape'
is set to 0 if shell escapes are disabled, 1 if they are enabled, and 2
if they are enabled with restrictions.
The purpose of this feature is to make it possible for TeX documents
to perform useful external actions in the common case of an individual
user running a known document on his or her own machine. In such
environments as CGI scripts or wikis where the input has to be
considered untrustworthy, shell escapes should be completely disabled.

(If anyone uses this feature and needs documentation, write
<tex-k AT tug.org>.)
This functionality is available only if the `--enable-ipc' option
was specified to `configure' during installation of Web2c (*note
Installation::).
If you define `IPC_DEBUG' before compilation (e.g., with `make
XCFLAGS=-DIPC_DEBUG'), TeX will print messages to standard error about
its socket operations. This may be helpful if you are, well, debugging.

4.7 TeX extensions
==================
The base TeX program has been extended in many ways. Here's a partial
list.
e-TeX
Adds many new primitives, including right-to-left typesetting and
more registers. Now frozen.
Aleph
This adds Unicode support, right-to-left typesetting, and more.
Omega was the original program. Aleph is an updated version with
a variety of bug fixes, and includes e-TeX. Aleph is not actively
maintained.
pdfTeX
Can produce PDF as well as DVI files. It also incorporates the
e-TeX extensions, new primitives for hypertext and
micro-typography, reading/writing from pipes, and much more. Home
page: `http://pdftex.org'.
luaTeX
Based on pdfTeX, this also embeds the Lua programming language
(`http://lua.org') and opens up the TeX typesetting engine to
control from Lua. Home page: `http://luatex.org'.
XeTeX
Combines support for Unicode input and OpenType- and system fonts
with the capabilities of pdfTeX. Home page:
`http://tug.org/xetex'.

5 Metafont: Creating typeface families
**************************************
Metafont is a system for producing shapes; it was designed for producing
complete typeface families, but it can also produce geometric designs,
dingbats, etc. And it has considerable mathematical and
equation-solving capabilities which can be useful entirely on their own.
Metafont is a batch language, like C or Pascal: you compile a
Metafont program into a corresponding font, rather than interactively
drawing lines or curves. This approach has both considerable
disadvantages (people unfamiliar with conventional programming
languages will be unlikely to find it usable) and considerable
advantages (you can make your design intentions specific and
parameterizable). For a complete description of the Metafont language,
see `The METAFONTbook' (*note References::).

File: web2c.info, Node: mf invocation, Next: Initial Metafont, Up: Metafont
5.1 `mf' invocation
===================
Metafont (usually invoked as `mf') reads character definitions
specified in the Metafont programming language, and outputs the
corresponding font. This section merely describes the options available
in the Web2c implementation. For a complete description of the Metafont
language, see `The Metafontbook' (*note References::).
Metafont processes its command line and determines its memory dump
(base) file in a way exactly analogous to MetaPost and TeX (*note tex
invocation::, and *note Memory dumps::). Synopses:
mf [OPTION]... [MFNAME[.mf]] [MF-COMMANDS]
mf [OPTION]... \FIRST-LINE
mf [OPTION]... &BASE ARGS
Most commonly, a Metafont invocation looks like this:
mf '\mode:=MODE; mag:=MAGNIFICATION; input MFNAME'
(The single quotes avoid unwanted interpretation by the shell.)
Metafont searches the usual places for the main input file MFNAME
(*note Supported file formats: (kpathsea)Supported file formats.),
extending MFNAME with `.mf' if necessary. To see all the relevant
paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before
running the program. By default, Metafont runs an external program
named `mktexmf' to create any nonexistent Metafont source files you
input. You can disable this at configure-time or runtime (*note mktex
configuration: (kpathsea)mktex configuration.). This is mostly for the
sake of the EC fonts, which can be generated at any size.
Metafont writes the main GF output to the file `BASEMFNAME.NNNgf',
where NNN is the font resolution in pixels per inch, and BASEMFNAME is
the basename of MFNAME, or `mfput' if no input file was specified. A
GF file contains bitmaps of the actual character shapes. Usually GF
files are converted immediately to PK files with GFtoPK (*note gftopk
invocation::), since PK files contain equivalent information, but are
more compact. (Metafont output in GF format rather than PK for only
historical reasons.)
Metafont also usually writes a metric file in TFM format to
`BASEMFNAME.tfm'. A TFM file contains character dimensions, kerns, and
ligatures, and spacing parameters. TeX reads only this .tfm file, not
the GF file.
The MODE in the example command above is a name referring to a
device definition (*note Modes::); for example, `localfont' or
`ljfour'. These device definitions must generally be precompiled into
the base file. If you leave this out, the default is `proof' mode, as
stated in `The Metafontbook', in which Metafont outputs at a resolution
of 2602dpi; this is usually not what you want. The remedy is simply to
assign a different mode--`localfont', for example.
The MAGNIFICATION assignment in the example command above is a
magnification factor; for example, if the device is 600dpi and you
specify `mag:=2', Metafont will produce output at 1200dpi. Very often,
the MAGNIFICATION is an expression such as `magstep(.5)', corresponding
to a TeX "magstep", which are factors of 1.2 * sqrt(2).
After running Metafont, you can use the font in a TeX document as
usual. For example:
\font\myfont = newfont
\myfont Now I am typesetting in my new font (minimum hamburgers).
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-[no]-file-line-error'
`-fmt=FMTNAME'
`-halt-on-error'
`-ini'
`-interaction=STRING'
`-jobname=STRING'
`-kpathsea-debug=NUMBER'
`-[no]parse-first-line'
`-output-directory'
`-progname=STRING'
`-recorder'
`-translate-file=TCXFILE'
`-8bit'
These options are common to TeX, Metafont, and MetaPost. *Note
Common options::.
`-mktex=FILETYPE'
`-no-mktex=FILETYPE'
Turn on or off the `mktex' script associated with FILETYPE. The
only value that makes sense for FILETYPE is `mf'.
File: web2c.info, Node: Initial Metafont, Next: Modes, Prev: mf invocation, Up: Metafont
5.2 Initial Metafont
====================
`inimf' is the "initial" form of Metafont, which does lengthy
initializations avoided by the "virgin" (`vir') form, so as to be
capable of dumping `.base' files (*note Memory dumps::). For a
detailed comparison of virgin and initial forms, see *note Initial and
virgin::. In past releases, a separate program `inimf' was installed
to invoke the initial form, but this is no longer the case.
For a list of options and other information, see *note mf
invocation::.
The only memory dump file commonly used with Metafont is the default
`plain.base', also known as `mf.base' (again, *note Memory dumps::).
It is created by default during installation, but you can also do so by
hand if necessary (e.g., if a Metafont update is issued):
mf -ini '\input plain; input modes; dump'
(The quotes prevent interpretation of the backslashes from the
shell.) Then install the resulting `plain.base' in `$(basedir)'
(`/usr/local/share/texmf/web2c' by default), and link `mf.base' to it.
For an explanation of the additional `modes.mf' file, see *note
Modes::. This file has no counterpart in TeX or MetaPost.
In the past, it was sometimes useful to create a base file
`cmmf.base' (a.k.a. `cm.base'), with the Computer Modern macros also
included in the base file. Nowadays, however, the additional time
required to read `cmbase.mf' is exceedingly small, usually not enough
to be worth the administrative hassle of updating the `cmmf.base' file
when you install a new version of `modes.mf'. People actually working
on a typeface may still find it worthwhile to create their own base
file, of course.
File: web2c.info, Node: Modes, Next: Online Metafont graphics, Prev: Initial Metafont, Up: Metafont
5.3 Modes: Device definitions for Metafont
==========================================
Running Metafont and creating Metafont base files requires information
that TeX and MetaPost do not: "mode" definitions which specify device
characteristics, so Metafont can properly rasterize the shapes.
When making a base file, a file containing modes for
locally-available devices should be input after `plain.mf'. One
commonly used file is `ftp://ftp.tug.org/tex/modes.mf'; it includes all
known definitions.
If, however, for some reason you have decreased the memory available
in your Metafont, you may need to copy `modes.mf' and remove the
definitions irrelevant to you (probably most of them) instead of using
it directly. (Or, if you're a Metafont hacker, maybe you can suggest a
way to redefine `mode_def' and/or `mode_setup'; right now, the amount
of memory used is approximately four times the total length of the
`mode_def' names, and that's a lot.)
If you have a device not included in `modes.mf', please see comments
in that file for how to create the new definition, and please send the
definition to <tex-fonts AT math.edu> to get it included in the next
release of `modes.mf'.
Usually, when you run Metafont you must supply the name of a mode
that was dumped in the base file. But you can also define the mode
characteristics dynamically, by invoking Metafont with an assignment to
`smode' instead of `mode', like this:
mf '\smode:="newmode.mf"; mag:=MAGNIFICATION; input MFNAME'
This is most useful when you are working on the definition of a new
mode.
The MAGNIFICATION and MFNAME arguments are explained in *note mf
invocation::. In the file `newmode.mf', you should have the following
(with no `mode_def' or `enddef'), if you are using `modes.mf'
conventions:
mode_param (pixels_per_inch, DPI);
mode_param (blacker, B);
mode_param (fillin, F);
mode_param (o_correction, O);
mode_common_setup_;
(Of course, you should use real numbers for DPI, B, F, and O.)
For more information on the use of `smode', or if you are not using
`modes.mf', see page 269 of `The Metafontbook'.

5.4 Online Metafont graphics
============================
The Web2c implementation of Metafont can do online graphics with a
number of devices. (See the Metafont manual for more information about
how to draw on your screen.) By default, no graphics support is
enabled.
Metafont examines the `MFTERM' environment variable or config file
value at runtime, or the `TERM' environment variable if `MFTERM' is not
set, to determine the device support to use. Naturally, only the
devices for which support has been compiled in can be selected.
Here is a table of the possibilities, showing the `MFTERM' value and
the corresponding `configure' option(s) in parentheses.
`epsf'
(`--enable-epsfwin') Pseudo-window server for Encapsulated
PostScript (see `web2c/window/epsf.c'). This device produces an
EPS file containing the graphics which would be displayed online on
other devices. The name of the EPS file defaults to metafont.eps
but can be changed by setting the MFEPSF environment variable to
the new filename. Contributed by Mathias Herberts.
`hp2627'
(`--enable-hp2627win') HP2627a color graphics terminals.
`mftalk'
(`--enable-mftalkwin') Generic window server (see
`web2c/window/mftalk.c').
`next'
(`--enable-next') NeXT window system. This requires a separate
program, called `DrawingServant', available separately. See the
`web2c/window/next.c'.
`regis'
(`--enable-regiswin') Regis terminals.
`sun'
(`--enable-suntoolswin') The old Suntools (not any flavor of X)
window system. (You can get the even older SunWindows `gfx' system
by using `sun-gfx.c'.)
`tek'
(`--enable-tektronixwin') Tektronix terminals.
`uniterm'
(`--enable-unitermwin') Uniterm, Simon Poole's emulator of a smart
Tektronix 4014 terminal. This may work with regular Tektronix
terminals as well; it's faster than the driver
`--enable-tektronixwin' selects.
`xterm'
`--with-x' The X window system (version 11).
There are two variants of the X11 support, one that works with the
Xt toolkit, and another that works directly with Xlib. The Xt
support is more efficient and has more functionality, so it is the
default. If you must use the Xlib support, use `configure --with-x
--with-kf-x-toolkit=no'.
Specify `--disable-mf-nowin' in order not to build a separate
non-windows-capable Metafont executable `mf-nowin' (or
`mf-nowin.exe').
You cannot specify any of the usual X options (e.g., `-geometry')
on the Metafont command line, but you can specify X resources in
your `~/.Xdefaults' or `~/.Xresources' file. The class name is
`Metafont'. If you're using the Xt support, all the usual X toolkit
resources are supported. If you're using the Xlib support, only
the `geometry' resource is supported.
You specify the X display to which Metafont connects in the
`DISPLAY' environment variable, as usual.
Writing support for a new device is straightforward. Aside from
defining the basic drawing routines that Metafont uses (see `mf.web'),
you only have to add another entry to the tables on the last page of
`web2c/lib/texmfmp.c'. Or you can write an independent program and use
MFtalk (see `web2c/window/mftalk.c').

5.5 GFtoDVI: Character proofs of fonts
======================================
GFtoDVI makes "proof sheets" from a GF bitmap file as output by, for
example, Metafont (*note Metafont::). This is an indispensable aid for
font designers or Metafont hackers. Synopsis:
gftodvi [OPTION]... GFNAME[gf]
The font GFNAME is searched for in the usual places (*note Glyph
lookup: (kpathsea)Glyph lookup.). To see all the relevant paths, set
the environment variable `KPATHSEA_DEBUG' to `-1' before running the
program.
The suffix `gf' is supplied if not already present. This suffix is
not an extension, no `.' precedes it; for instance, `cmr10.600gf'.
The output filename is the basename of GFNAME extended with `.dvi',
e.g., `gftodvi /wherever/foo.600gf' creates `./foo.dvi'.
The characters from GFNAME appear one per page in the DVI output,
with labels, titles, and annotations, as specified in Appendix H
(Hardcopy Proofs) of `The Metafontbook'.
GFtoDVI uses several fonts besides GFNAME itself:
* "gray font" (default `gray'): for the pixels that actually make up
the character. Simply using black is not right, since then labels,
key points, and other information could not be shown.
* "title font" (default `cmr8'): for the header information at the
top of each output page.
* "label font" (default `cmtt10'): for the labels on key points of
the figure.
* "slant font" (no default): for diagonal lines, which are otherwise
simulated using horizontal and vertical rules.
To change the default fonts, you must use `special' commands in your
Metafont source file, typically via commands like `slantfont slantlj4'.
There is no default slant font since no one printer is suitable as a
default. You can make your own by copying one of the existing files,
such as `.../fonts/source/public/misc/slantlj4.mf' and then running
`mf' on it.
For testing purposes, you may it useful to run `mf-nowin rtest' (hit
RETURN when it stops) to get a `gf' file of a thorn glyph. Or use `mf'
instead of `mf-nowin' to have the glyph(s) displayed on the screen.
After that, `gftodvi rtest.2602gf' should produce `rtest.dvi', which
you process as usual.
The program accepts the following option, as well as the standard
`-verbose', `-help', and `-version' (*note Common options::):
`-overflow-label-offset=POINTS'
Typeset the so-called overflow labels, if any, POINTS TeX points
from the right edge of the character bounding box. The default is
a little over two inches (ten million scaled points, to be
precise). Overflow equations are used to locate coordinates when
their actual position is too crowded with other information.
File: web2c.info, Node: mft invocation, Prev: gftodvi invocation, Up: Metafont
5.6 MFT: Prettyprinting Metafont source
=======================================
MFT translates a Metafont program into a TeX document suitable for
typesetting, with the aid of TeX macros defined in the file
`mftmac.tex'. Synopsis:
mft [OPTION]... MFNAME[.mf]
MFT searches the usual places for MFNAME (*note Supported file
formats: (kpathsea)Supported file formats.). To see all the relevant
paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before
running the program. The output goes to the basename of MFNAME extended
with `.tex', e.g., `mft /wherever/foo.mf' creates `./foo.tex'.
Line breaks in the input are carried over into the output; moreover,
blank spaces at the beginning of a line are converted to quads of
indentation in the output. Thus, you have full control over the
indentation and line breaks. Each line of input is translated
independently of the others.
Further control is allowed via Metafont comments:
* Metafont comments following a single `%' should be valid TeX
input. But Metafont material can be included within vertical bars
in a comment; this will be translated by MFT as if it were regular
Metafont code. For example, a comment like `% |x2r| is the tip of
the bowl' will be translated into the TeX `% $x_{2r}$ is the ...',
i.e., the `x2r' is treated as an identifier.
* `%%' indicates that the remainder of an input line should be copied
verbatim to the output. This is typically used to introduce
additional TeX material at the beginning or an MFT job, e.g. code
to modify the standard layout or the formatting macros defined in
`mftmac.tex', or to add a line saying `%%\bye' at the end of the
job. (MFT doesn't add this automatically in order to allow
processing several files produces by MFT in the same TeX job.)
* `%%% TOKEN1 OTHER-TOKENS' introduces a change in MFT's formatting
rules; all the OTHER-TOKENS will henceforth be translated
according to the current conventions for TOKEN1. The tokens must
be symbolic (i.e., not numeric or string tokens). For example, the
input line
%%% addto fill draw filldraw
says to format the `fill', `draw', and `filldraw' operations of
plain Metafont just like the primitive token `addto', i.e., in
boldface type. Without such reformatting commands, MFT would
treat `fill' like an ordinary tag or variable name. In fact, you
need a `%%%' command even to get parentheses to act like
delimiters.
* `%%%%' introduces an MFT comment, i.e., MFT ignores the remainder
of such a line.
* Five or more `%' signs should not be used.
(The above description was edited from `mft.web', written by
D.E. Knuth.)
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-change=CHFILE[.ch]'
Apply the change file CHFILE as with Tangle and Weave (*note
WEB::).
`-style=MFTFILE[.mft]'
Read MFTFILE before anything else; a MFT style file typically
contains only MFT directives as described above. The default
style file is named `plain.mft', which defines this properly for
programs using plain Metafont. The MFT files is searched along the
`MFTINPUTS' path; see *note Supported file formats:
(kpathsea)Supported file formats.
Other examples of MFT style files are `cmbase.mft', which defines
formatting rules for the macros defined in `cm.base', and `e.mft',
which was used in the production of Knuth's Volume E, `Computer
Modern Typefaces'.
Using an appropriate MFT style file, it is also possible to
configure MFT for typesetting MetaPost sources. However, MFT does
not search the usual places for MetaPost input files.
If you use eight-bit characters in the input file, they are passed
on verbatim to the TeX output file; it is up to you to configure TeX to
print these properly.

6 MetaPost: Creating technical illustrations
********************************************
MetaPost is a picture-drawing language similar to Metafont (*note
Metafont::), but instead of outputting bitmaps in a "font", it outputs
PostScript commands. It's primarily intended for creating technical
illustrations.
MetaPost also provides for arbitrary integration of text and
graphics in a natural way, using any typesetter (TeX and Troff are both
supported) and a number of other subsidiary programs, described below.

File: web2c.info, Node: mpost invocation, Next: Initial MetaPost, Up: MetaPost
6.1 `mpost' invocation
======================
MetaPost (installed as `mpost') reads a series of pictures specified in
the MetaPost programming language, and outputs corresponding PostScript
code. This section merely describes the options available in the Web2c
implementation. For a complete description of the MetaPost language,
see AT&T technical report CSTR-162, generally available in
`TEXMF/doc/metapost/', where TEXMF is the root of TeX directory
structure. See also:
* `http://cm.bell-labs.com/who/hobby/MetaPost.html' (the
MetaPost author's home page);
* `http://tug.org/metapost' (papers, packages, and related
information).
Also, a standard MetaPost package for drawing graphs is documented in
AT&T technical report CSTR-164, available as the file `mpgraph.ps',
generally stored alongside `mpman.ps'.
MetaPost processes its command line and determines its memory dump
(mem) file in a way exactly analogous to Metafont and TeX (*note `tex'
invocation: tex invocation, and *note Memory dumps::). Synopses:
mpost [OPTION]... [MPNAME[.mp]] [MP-COMMANDS]
mpost [OPTION]... \FIRST-LINE
mpost [OPTION]... &MEM ARGS
MetaPost searches the usual places for the main input file MPNAME
(*note Supported file formats: (kpathsea)Supported file formats.),
extending MPNAME with `.mp' if necessary. To see all the relevant
paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before
running the program.
MetaPost writes its PostScript output to a series of files
`BASEMPNAME.NNN' (or perhaps `BASEMPNAME.ps', very occasionally
`BASEMPNAME.tfm'), where NNN are the figure numbers specified in the
input, typically to the `beginfig' macro, and BASEMPNAME is the
basename of MPNAME, or `mpout' if no input file was specified.
MetaPost uses the `.ps' extension when the figure number is out of
range, e.g., if you say `beginfig(-1)'.
You can use the output files as figures in a TeX document just as
with any other PostScript figures. For example, with this TeX command:
\special{psfile="FILENAME"}
or by using `epsf.tex' (*note EPSF macros: (dvips)EPSF macros.).
The MetaPost construct
btex ... TEX-INPUT ... etex
generates a MetaPost picture expression corresponding to TEX-INPUT.
The construct
verbatimtex ... TEX-INPUT ... etex
simply passes the TEX-INPUT through to TeX. For example, if you are
using LaTeX, your MetaPost input file must start with a `verbatimtex'
block that gives the necessary `\documentclass' (or `\documentstyle')
`\begin{document}' command. You will also need to set the enviroment
variable `TEX' to `latex'.
TEX-INPUT need not be specifically TeX input; it could also be
Troff. In that case, you will need the `-m pictures' Troff macro
package (unfortunately absent from many Troff implementations), or an
equivalent such as the `-m pspic' macros from GNU groff described in
grops(1).
Naturally, you must use fonts that are supported by the typesetter;
specifically, you'll probably want to use standard PostScript fonts with
Troff. And only the TeX system understands Computer Modern or other
Metafont fonts; you can also use PostScript fonts with TeX, of course.
MetaPost-generated PostScript figures which do use Computer Modern
fonts for labels cannot be directly previewed or printed. Instead, you
must include them in a TeX document and run the resulting DVI file
through Dvips to arrange for the downloading of the required fonts
(*note Fonts in figures: (dvips)Fonts in figures.). To help with this,
the MetaPost distribution provides a small TeX file `mproof.tex' which
is typically called as:
tex mproof MP-OUTPUT-FILES... ; dvips mproof -o
The resulting file `mproof.ps' can then be printed or previewed.
To generate EPSF files, set the internal MetaPost variable
`prologues' positive. To make the output files self-contained, use
only standard PostScript fonts. MetaPost reads the same `psfonts.map'
file as Dvips, to determine PostScript fonts that need to be downloaded
(*note psfonts.map: (dvips)psfonts.map.).
It is posible for pdfTeX to read MetaPost output directly; this is
in contrast to general EPSF files, which have to be converted for use
with PDF output. The easiest way is to name the MetaPost output files
with the `.mps' extension. Then the LaTeX `\includegraphics' command,
for example, will be able to read them, even when outputting PDF.
MetaPost can write output files, via the `write' primitive; this
opens a security hole. *Note tex invocation::.
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-[no]-file-line-error'
`-fmt=FMTNAME'
`-halt-on-error'
`-ini'
`-interaction=STRING'
`-jobname=STRING'

`-[no]parse-first-line'
`-output-directory'
`-progname=STRING'
`-recorder'
`-translate-file=TCXFILE'

These options are common to TeX, Metafont, and MetaPost. *Note
Common options::.
`-T'
`-troff'
Set the `prologues' internal variable to `1'.
`-tex=TEXPROGRAM'
When this option is given, the program TEXPROGRAM is used to
typeset the labels.

6.2 Initial MetaPost
====================
As of MetaPost 1.504 (TeX Live 2011), MetaPost no longer dumps `.mem'
files (*note Memory dumps::) and does not distinguish virgin and
initial forms (*note Initial and virgin::). Instead, the "initial"
file name is read in its source form--that is, `mpost.mp' when the
program is invoked as `mpost'.
For a list of options and other information, see *note mpost
invocation::.
MetaPost provides a format with all the features of plain Metafont,
called `mfplain'. You can use that in the same way; just run `mfplain'
instead of `mpost'. This lets you directly process Metafont source
files with MetaPost, producing character proofs (one file for each
character) similar to those produced with Metafont in proof mode and
GFtoDVI (*note gftodvi invocation::).

6.3 DVItoMP: DVI to MPX conversion
==================================
DVItoMP converts DVI files into low-level MetaPost commands in a
so-called MPX file. Synopsis:

If MPXFILE is not specified, the output goes to the basename of DVIFILE
extended with `.mpx', e.g., `dvitomp /wherever/foo.dvi' creates
`./foo.mpx'.
DVItoMP supports Dvips-style color specials, such as `color push
NAME' and `color pop', outputting them as `withcolor' MetaPost commands.
The only options are `-help' and `-version' (*note Common options::).

7.1 BibTeX invocation
=====================
BibTeX creates a printable bibliography (`.bbl') file from references
in a `.aux' file, generally written by TeX or LaTeX. The `.bbl' file
is then incorporated on a subsequent run. The basic bibliographic
information comes from `.bib' files, and a BibTeX style (`.bst') file
controls the precise contents of the `.bbl' file. Synopsis:
bibtex [OPTION]... AUXFILE[.aux]
The output goes to the basename of AUXFILE extended with `.bbl'; for
example, `bibtex /wherever/foo.aux' creates `./foo.bbl'. BibTeX also
writes a log file to the basename of AUXFILE extended with `.blg'.
The names of the `.bib' and `.bst' files are specified in the `.aux'
file as well, via the `\bibliography' and `\bibliographystyle' (La)TeX
macros. BibTeX searches for `.bib' files using the `BIBINPUTS' and
`TEXBIB' paths, and for `.bst' files using `BSTINPUTS' (*note Supported
file formats: (kpathsea)Supported file formats.). It does no path
searching for `.aux' files.
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-terse'
Suppress the program banner and progress reports normally output.
`-min-crossrefs=N'
If at least N (2 by default) bibliography entries refer to another
entry E via their `crossref' field, include E in the .bbl file,
even if it was not explicitly referenced in the .aux file. For
example, E might be a conference proceedings as a whole, with the
cross-referencing entries being individual articles published in
the proceedings. In some circumstances, you may want to avoid
these automatic inclusions altogether; to do this, make N a
sufficiently large number.

7.2 Basic BibTeX style files
============================
Here are descriptions of the four standard and four semi-standard basic
BibTeX styles. `CTAN:/biblio/bibtex' contains these and many more (for
CTAN info, *note unixtex.ftp: (kpathsea)unixtex.ftp.).
`plain'
Sorts entries alphabetically, with numeric labels. Generally
formatted according to van Leunen's `A Handbook for Scholars'.
The other style files listed here are based on `plain'.
`abbrv'
First names, month names, and journal names are abbreviated.
`acm'
Names are printed in small caps.
`alpha'
Alphanumeric labels, e.g., `Knu66'.
`apalike'
No labels at all; instead, the year appears in parentheses after
the author. Use this in conjunction with `apalike.tex' (plain
TeX) or `apalike.sty' (LaTeX), which also changes the citations in
the text to be `(AUTHOR, YEAR)'.
`ieeetr'
Numeric labels, entries in citation order, IEEE abbreviations,
article titles in quotes.
`siam'
Numeric labels, alphabetic order, `Math. Reviews' abbreviations,
names in small caps.
`unsrt'
Lists entries in citation order, i.e., unsorted.
`btxbst.doc'
The template file and documentation for the standard styles.

8 WEB: Literate programming
***************************
"WEB" languages allow you to write a single source file that can
produce both a compilable program and a well-formatted document
describing the program in as much detail as you wish to prepare.
Writing in this kind of dual-purpose language is called "literate
programming". (The Usenet newsgroup `comp.programming.literate' is
devoted to this subject.)
WEB-like languages have been implemented with many pairs of base
languages: Cweb provides C and Troff (*note References::); CWEB provides
C and TeX (`CTAN:/web/c_cpp/cweb'); Spiderweb provides C, C++, Awk,
Ada, many others, and TeX (`CTAN:/web/spiderweb'); and, of course, the
original WEB provides Pascal and TeX, the implementation languages for
the original TeX, Metafont, MetaPost, and related programs to come from
the TeX project at Stanford.
The original WEB language is documented in the file `webman.tex',
which is included in the `ftp://ftp.tug.org/tex/lib.tar.gz' archive
(and available in many other places, of course).

8.1 Tangle: Translate WEB to Pascal
===================================
Tangle creates a compilable Pascal program from a WEB source file
(*note WEB::). Synopsis:
tangle [OPTION]... WEBFILE[.web] [CHANGEFILE[.ch]]
The Pascal output is written to the basename of WEBFILE extended with
`.p'; for example, `tangle /wherever/foo.web' creates `./foo.p'.
Tangle applies CHANGEFILE to WEBFILE before writing the output; by
default, there is no change file.
If the program makes use of the WEB string facility, Tangle writes
the string pool to the basename of WEBFILE extended with `.pool'.
The Pascal output is packed into lines of 72 characters or less, with
the only concession to readability being the termination of lines at
semicolons when this can be done conveniently.
The program accepts the following options, as well as the standard
`--help' and `--version' (*note Common options::):
`-length=NUMBER'
The number of characters that are considered significant in an
identifier. Whether underline characters are counted depends on
the `-underline' option. The default value is 32, the original
tangle used 7, but this proved too restrictive for use by Web2c.
`-lowercase'
`-mixedcase'
`-uppercase'
These options specify the case of identifiers in the output of
tangle. If `-uppercase' (`-lowercase') is specified, tangle will
convert all identfiers to uppercase (lowercase). The default is
`-mixedcase', which specifies that the case will not be changed.
`-underline'
When this option is given, tangle does not strip underline
characters from identifiers.
`-loose'
`-strict'
These options specify how strict tangle must be when checking
identifiers for equality. The default is `-loose', which means
that tangle will follow the rules set by the case-smashing and
underline options above. If `-strict' is set, then identifiers
will always be stripped of underlines and converted to uppercase
before checking whether they collide.

8.2 Weave: Translate WEB to TeX
===============================
Weave creates a TeX document from a WEB source file (*note WEB::),
assuming various macros defined in `webmac.tex'. It takes care of
typographic details such as page layout, indentation, and italicizing
identifiers. It also automatically gathers and outputs extensive
cross-reference information. Synopsis:
weave [OPTION]... WEBFILE[.web] [CHANGEFILE[.ch]]
The output is to the basename of WEBFILE extended with `.tex'; for
example, `weave /wherever/foo.web' creates `./foo.tex'. Weave applies
CHANGEFILE to WEBFILE before writing the output; by default, there is
no change file.
The program accepts the following option, as well as the standard
`-verbose', `-help' and `-version' (*note Common options::):
`-x'
Omit the cross-reference information: the index, the list of WEB
module names, and the table of contents (an empty `CONTENTS.tex'
file will still be written when the Weave output file is processed
by TeX using the default `webmac.tex', though).
Conventionally, WEB programmers should define the TeX `\title' macro
at the beginning of the source file. Also, to get output of only
changed modules, one can say `\let\maybe=\iffalse' (usually as the
first change in the change file).
File: web2c.info, Node: pooltype invocation, Prev: weave invocation, Up: WEB
8.3 Pooltype: Display WEB pool files
====================================
Pooltype shows the so-called "string number" of each string in a WEB
pool file (*note WEB::), as output by Tangle (*note tangle
invocation::), including the first 256 strings corresponding to the
possible input characters. Pooltype primarily serves as an example of
WEB conventions to implementors of the TeX system. Synopsis:
pooltype [OPTION]... POOLFILE[.pool]
No path searching is done for POOLFILE. Output is to standard output.
The only options are `--help' and `--version' (*note Common
options::).
As an example of the output, here is the (edited) output for
`tex.pool':
0: "^^@"
1: "^^A"
...
255: "^^ff"
256: "pool size"
...
1314: "Using character substitution: "
(23617 characters in all.)
In Metafont and MetaPost, the first 256 characters are actually
represented as single bytes (i.e., themselves), not in the `^^'
notation. Consider Pooltype as showing the results after conversion for
output.

9 DVI utilities
***************
TeX outputs a file in "DVI" (DeVice Independent) format as a compact
representation of the original document. DVI files can be translated
to meet the requirements of a real physical device, such as PostScript
printers (*note Introduction: (dvips)Top.), PCL printers (see
dvilj(1)), and X displays (see xdvi(1)). In fact, DVI translators are
available for virtually all common devices: see `CTAN:/dviware' (for
CTAN info, *note unixtex.ftp: (kpathsea)unixtex.ftp.).
For the precise definition of the DVI file format, see (for example)
the source file `web2c/dvitype.web'.
The DVI-processing programs in the Web2c distribution are not device
drivers; they perform generic utility functions.

9.1 DVIcopy: Canonicalize virtual font references
=================================================
DVIcopy reads a DVI file, expands any references to virtual fonts
(*note Virtual fonts: (dvips)Virtual fonts.) to base fonts, and writes
the resulting DVI file. Thus you can use virtual fonts even if your DVI
processor does not support them, by passing the documents through
DVIcopy first. Synopsis:
dvicopy [OPTION]... [INDVI[.dvi] [OUTDVI[.dvi]]]
DVIcopy reads standard input if INDVI is not specified, and writes
standard output if OUTDVI is not specified.
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-magnification=INTEGER'
Override existing magnification in INDVI with INTEGER; 1000
specifies no magnification. This is equivalent to setting TeX's
`\mag' parameter.
`-max-pages=N'
Process N pages; default is one million.
`-page-start=PAGE-SPEC'
Start at the first page matching PAGE-SPEC, which is one or more
(signed) integers separated by periods, corresponding to TeX's
`\count0...9' parameters at `\shipout' time; `*' matches anything.
Examples: `3', `1.*.-4'.

9.2 DVItype: Plain text transliteration of DVI files
====================================================
DVItype translates a DeVice Independent (DVI) file (as output by TeX,
for example) to a plain text file that humans can read. It also serves
as a DVI-validating program, i.e., if DVItype can read a file, it's
correct. Synopsis:
dvitype [OPTION]... DVIFILE[.dvi]
DVItype does not read any bitmap files, but it does read TFM files for
fonts referenced in DVIFILE. The usual places are searched (*note
Supported file formats: (kpathsea)Supported file formats.). To see all
the relevant paths, set the environment variable `KPATHSEA_DEBUG' to
`-1' before running the program.
Output goes to standard output.
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-dpi=REAL'
Do pixel movement calculations at REAL pixels per inch; default
300.0.
`-magnification=INTEGER'
Override existing magnification in INDVI with INTEGER; 1000
specifies no magnification. This is equivalent to setting TeX's
`\mag' parameter.
`-max-pages=N'
Process N pages; default is one million.
`-output-level=N'
Verbosity level of output, from 0 to 4 (default 4):
* 0: Global document information only.
* 1: Most DVI commands included, and typeset characters
summarized.
* 2: Character and movement commands explicitly included.
* 3: DVI stack and current position calculations included.
* 4: Same information as level 3, but DVItype does random
positioning in the file, reading the DVI postamble first.
`-page-start=PAGE-SPEC'
Start at the first page matching PAGE-SPEC, which is one or more
(signed) integers separated by periods, corresponding to TeX's
`\count0...9' parameters at `\shipout' time; `*' matches anything.
Examples: `1', `5.*.-9'.
`-show-opcodes'
Show numeric opcode values (in decimal) for DVI commands, in braces
after the command name. This can help in debugging DVI utilities.
We use decimal because in the DVI format documentation (in
`dvitype.web', among others) the opcodes are shown in decimal.

The Web2c programs described here convert between various TeX-related
font formats; the first section below briefly describes the formats.
GFtoPK is the only one that is routinely used, as Metafont outputs GF
format, but it's most efficient for device drivers to use PK.
The precise definitions of the PK, GF, TFM, PL, VF, and VPL formats

10.1 Font file formats
======================
(For another perspective on this, *note Font concepts: (dvips)Font
concepts.).
Font files come in several varieties, with suffixes like:
.tfm .*pk .*gf .*pxl (obsolete) .pl .mf .vf .vpl
Each represents a file format.
A TFM (TeX font metric) file is a compact binary file that contains
information about each character in a font, about combinations of
characters within that font, and about the font as a whole. The font
metric information contained in TFM files is device-independent units is
used by TeX to do typesetting. Unlike the bitmap (raster) fonts
described below, TFM font files contain no information about the shapes
of characters. They describe rectangular areas and combinations
thereof, but not what will eventually be printed in those areas.
Since TeX does scaling calculations, one TFM file serves for all
magnifications of a given typeface. On the other hand, the best printed
results are obtained when magnified (or reduced fonts) are not produced
geometrically (as done by PostScript, for example) but rather optically,
with each size a separate design (as done with Computer Modern and the
EC fonts, for example); then a separate TFM file is needed for each
size.
At any rate, TeX produces a DVI (DeVice Independent) file from your
source document. In order to print DVI files on real devices, you need
font files defining digitized character shapes and other data. Then
previewers and printer-driver programs can translate your DVI files into
something usable by your monitor or printer. Bitmap fonts come with
suffixes such as `.600pk' or `.600gf' or `.3000pxl', where the `600' is
the horizontal dots-per-inch resolution at which the font was produced,
and the `pk' or `gf' or `pxl' indicates the font format. Outline fonts
in PostScript Type 1 format have suffixes such as `.pfa' or `.pfb'.
Fonts in pk (packed) format are in the tightly packed raster format
that is pretty much the standard today. They take up less space than
fonts in the gf (generic font) format that Metafont generates, and far
less space than fonts in pxl format. Fonts in pxl format take up gross
amounts of disk space and permit only 128 characters. They are
obsolete.
Font files with the `.pl' (property list) suffix are the plain text
(human-readable) analog of the binary `.tfm' files. The TFtoPL and
PLtoTF programs convert between the two formats (*note tftopl
invocation:: and *note pltotf invocation::).
Font files with the `.mf' suffix are in Metafont source format.
These are the files used by Metafont to generate rastered fonts for
specific typefaces at specific magnifications for the specific
resolution and type of mapping used by your device.
The suffix `.vf' identifies "virtual font" files, for which `.vpl'
is the human-readable analog. See *Note vftovp invocation::, and *note
vptovf invocation::. For further discussion of virtual fonts, see
`CTAN:/doc/virtual-fonts.knuth', `CTAN:/help/virtualfonts.txt', and
*note Virtual fonts: (dvips)Virtual fonts.

distribution by Pierre MacKay and Elizabeth Tachikawa.)

10.2 GFtoPK: Generic to packed font conversion
==============================================
GFtoPK converts a generic font (GF) file output by, for example,
Metafont (*note mf invocation::) to a packed font (PK) file. PK files
are considerably smaller than the corresponding gf files, so they are
generally the bitmap font format of choice. Some DVI-processing
programs, notably Dvips, only support PK files and not GF files.
Synopsis:
gftopk [OPTION]... GFNAME.DPI[gf] [PKFILE]
The font GFNAME is searched for in the usual places (*note Glyph
lookup: (kpathsea)Glyph lookup.). To see all the relevant paths, set
the environment variable `KPATHSEA_DEBUG' to `-1' before running the
program.
The suffix `gf' is supplied if not already present. This suffix is
not an extension; no `.' precedes it: for instance, `cmr10.600gf'.
If PKFILE is not specified, the output is written to the basename of
`GFNAME.DPIpk', e.g., `gftopk /wherever/cmr10.600gf' creates
`./cmr10.600pk'.
The only options are `--verbose', `--help', and `--version' (*note
Common options::).
File: web2c.info, Node: pktogf invocation, Next: pktype invocation, Prev: gftopk invocation, Up: Font utilities
10.3 PKtoGF: Packed to generic font conversion
==============================================
PKtoGF converts a packed font (PK) file to a generic font (GF) file.
Since PK format is much more compact than GF format, the most likely
reason to do this is to run GFtype (*note gftype invocation::) on the
result, so you can see the bitmap images. Also, a few old utility
programs do not support PK format. Synopsis:
pktogf [OPTION]... PKNAME.DPI[pk] [GFFILE]
The font PKNAME is searched for in the usual places (*note Glyph
lookup: (kpathsea)Glyph lookup.). To see all the relevant paths, set
the environment variable `KPATHSEA_DEBUG' to `-1' before running the
program.
The suffix `pk' is supplied if not already present. This suffix is
not an extension; no `.' precedes it: for instance, `cmr10.600pk'.
If GFFILE is not specified, the output is written to the basename of
`PKNAME.DPIgf', e.g., `pktogf /wherever/cmr10.600pk' creates
`./cmr10.600gf'.
The only options are `--verbose', `--help', and `--version' (*note
Common options::).

10.4 PKtype: Plain text transliteration of packed fonts
=======================================================
PKtype translates a packed font (PK) bitmap file (as output by GFtoPK,
for example) to a plain text file that humans can read. It also serves
as a PK-validating program, i.e., if PKtype can read a file, it's
correct. Synopsis:
pktype PKNAME.DPI[pk]
The font PKNAME is searched for in the usual places (*note Glyph
lookup: (kpathsea)Glyph lookup.). To see all the relevant paths, set
the environment variable `KPATHSEA_DEBUG' to `-1' before running the
program.
The suffix `pk' is supplied if not already present. This suffix is
not an extension; no `.' precedes it: for instance, `cmr10.600pk'.
The translation is written to standard output.
The only options are `-help' and `-version' (*note Common options::).
As an example of the output, here is the (abridged) translation of
the letter `K' in `cmr10', as rendered at 600dpi with the mode `ljfour'
from `modes.mf' (available from `ftp://ftp.tug.org/tex/modes.mf').
955: Flag byte = 184 Character = 75 Packet length = 174
Dynamic packing variable = 11
TFM width = 815562 dx = 4259840
Height = 57 Width = 57 X-offset = -3 Y-offset = 56

...
(14)9(24)12(5)[2]23(13)21
Explanation:
`955'
The byte position in the file where this character starts.
`Flag byte'
`Dynamic packing variable'
Related to the packing for this character; see the source code.
`Character'
The character code, in decimal.
`Packet length'
The total length of this character definition, in bytes.
`TFM width'
The device-independent (TFM) width of this character. It is 2^24
times the ratio of the true width to the font's design size.
`dx'
The device-dependent width, in "scaled pixels", i.e., units of
horizontal pixels times 2^16.
`Height'
`Width'
The bitmap height and width, in pixels.
`X-offset'
`Y-offset'
Horizontal and vertical offset from the upper left pixel to the
reference (origin) pixel for this character, in pixels (right and
down are positive). The "reference pixel" is the pixel that
occupies the unit square in Metafont; the Metafont reference point
is the lower left hand corner of this pixel. Put another way, the
x-offset is the negative of the left side bearing; the right side
bearing is the horizontal escapement minus the bitmap width plus
the x-offset.
`[2]23(16)...'
Finally, run lengths of black pixels alternate with parenthesized
run lengths of white pixels, and brackets indicate a repeated row.

10.5 GFtype: Plain text transliteration of generic fonts
========================================================
GFtype translates a generic font (GF) bitmap file (as output by
Metafont, for example) to a plain text file that humans can read. It
also serves as a GF-validating program, i.e., if GFtype can read a file,
it's correct. Synopsis:
gftype [OPTION]... GFNAME.DPI[gf]
The font GFNAME is searched for in the usual places (*note Glyph
lookup: (kpathsea)Glyph lookup.). To see all the relevant paths, set
the environment variable `KPATHSEA_DEBUG' to `-1' before running the
program.
The suffix `gf' is supplied if not already present. This suffix is
not an extension; no `.' precedes it: for instance, `cmr10.600gf'.
The translation is written to standard output.
The program accepts the following options, as well as the standard
`-help' and `-version' (*note Common options::):
`-images'
Show the characters' bitmaps using asterisks and spaces.
`-mnemonics'
Translate all commands in the GF file.
As an example of the output, here is the (abrdiged) translation of
the letter `K' in `cmr10', as rendered at 600dpi with the mode `ljfour'
from `modes.mf' (available from `ftp://ftp.tug.org/tex/modes.mf'), with
both `-mnemonics' and `-images' enabled.
GFtype outputs the information about a character in two places: a
main definition and a one-line summary at the end. We show both. Here
is the main definition:
2033: beginning of char 75: 3<=m<=60 0<=n<=56
(initially n=56) paint (0)24(12)20
2043: newrow 0 (n=55) paint 24(12)20

.<--This pixel's upper left corner is at (3,0) in METAFONT coordinates
Explanation:
`2033'
`2043'
`...'
The byte position in the file where each GF command starts.
`beginning of char 75'
The character code, in decimal.
`3<=m<=60 0<=n<=56'
The character's bitmap lies between 3 and 60 (inclusive)
horizontally, and between 0 and 56 (inclusive) vertically. (m is a
column position and n is a row position.) Thus, 3 is the left side
bearing. The right side bearing is the horizontal escapement
(given below) minus the maximum m.
`(initially n=56) paint (0)24(12)20'
The first row of pixels: 0 white pixels, 24 black pixels, 12 white
pixels, etc.
`newrow 0 (n=55) paint 24(12)20'
The second row of pixels, with zero leading white pixels on the
row.
`eoc'
The end of the main character definition.
Here is the GF postamble information that GFtype outputs at the end:
Character 75: dx 4259840 (65), width 815562 (64.57289), loc 2033
Explanation:
`dx'
The device-dependent width, in "scaled pixels", i.e., units of
horizontal pixels times 2^16. The `(65)' is simply the same number
rounded. If the vertical escapement is nonzero, it would appear
here as a `dy' value.
`width'
The device-independent (TFM) width of this character. It is 2^24
times the ratio of the true width to the font's design size. The
`64.57289' is the same number converted to pixels.
`loc'
The byte position in the file where this character starts.

10.6 TFtoPL: TeX font metric to property list conversion
========================================================
TFtoPL translates a TeX font metric (TFM, *note Metric files:
(dvips)Metric files.) file (as output by Metafont, for example) to
"property list format" (a list of parenthesized items describing the
font) that humans can edit or read. This program is mostly used by
people debugging TeX implementations, writing font utilities, etc.
Synopsis:
tftopl [OPTION]... TFMNAME[.tfm] [PLFILE[.pl]]
The font TFMNAME (extended with `.tfm' if necessary) is searched for
in the usual places (*note Supported file formats: (kpathsea)Supported
file formats.). To see all the relevant paths, set the environment
variable `KPATHSEA_DEBUG' to `-1' before running the program.
If PLFILE (which is extended with `.pl' if necessary) is not
specified, the property list file is written to standard output. The
property list file can be converted back to TFM format by the companion
program TFtoPL (see the next section).
The program accepts the following option, as well as the standard
`-verbose', `-help' and `-version' (*note Common options::):
`-charcode-format=TYPE'
Output character codes in the PL file according to TYPE: either
`octal' or `ascii'. Default is `ascii' for letters and digits,
octal for all other characters. Exception: if the font's coding
scheme starts with `TeX math sy' or `TeX math ex', all character
codes are output in octal.
In `ascii' format, character codes that correspond to graphic
characters, except for left and right parentheses, are output as a
`C' followed by the single character: `C K', for example. In
octal format, character codes are output as the letter `O' followed
by octal digits, as in `O 113' for `K'.
`octal' format is useful for symbol and other non-alphabetic fonts,
where using ASCII characters for the character codes is merely
confusing.
As an example of the output, here is the (abridged) property list
translation of `cmr10.tfm':
(FAMILY CMR)
(FACE O 352)
(CODINGSCHEME TEX TEXT)
(DESIGNSIZE R 10.0)

...
)
)
...
As you can see, the general format is a list of parenthesized
"properties", nested where necessary.
* The first few items (`FAMILY', `FACE', and so on) are the
so-called "headerbyte" information from Metafont, giving general
information about the font.
* The `FONTDIMEN' property defines the TeX `\fontdimen' values.
* The `LIGTABLE' property defines the ligature and kerning table.
`LIG' properties define ligatures: in the example above, an `f'
(in the `LABEL') followed by an `i' is a ligature, i.e., a
typesetting program like TeX replaces those two consecutive
characters by the character at position octal '014 in the current
font--presumably the `fi' ligature. `KRN' properties define
kerns: if an `f' is followed by character octal '047 (an
apostrophe), TeX inserts a small amount of space between them:
0.077779 times the design size the font was loaded at (about
three-quarters of a printer's point by default in this case, or
.001 inches).
* The `CHARACTER' property defines the dimensions of a character: its
width, height, depth, and italic correction, also in design-size
units, as explained in the previous item. For our example `f',
the depth is zero, so that property is omitted. TFtoPL also
inserts any kerns and ligatures for this character as a comment.

10.7 PLtoTF: Property list to TeX font metric conversion
========================================================
PLtoTF translates a property list file (as output by TFtoPL, for
example) to TeX font metric (TFM, *note Metric files: (dvips)Metric
files.) format. It's much easier for both programs and humans to
create the (plain text) property list files and let PLtoTF take care of
creating the binary TFM equivalent than to output TFM files directly.
Synopsis:
pltotf [OPTION]... PLFILE[.pl] [TFMFILE[.tfm]]
If TFMFILE (extended with `.tfm' if necessary) is not specified, the
TFM file is written to the basename of `PLFILE.tfm', e.g., `pltotf
/wherever/cmr10.pl' creates `./cmr10.tfm'. (Since TFM files are
binary, writing to standard output by default is undesirable.)
The only options are `-verbose', `-help', and `-version' (*note
Common options::).
For an example of property list format, see the previous section.
File: web2c.info, Node: vftovp invocation, Next: vptovf invocation, Prev: pltotf invocation, Up: Font utilities
10.8 VFtoVP: Virtual font to virtual property lists
===================================================
VFtoVP translates a virtual font metric (VF, *note Virtual fonts:
(dvips)Virtual fonts.) file and its accompanying TeX font metric (TFM,
*note Metric files: (dvips)Metric files.) file (as output by VPtoVF, for
example) to "virtual property list format" (a list of parenthesized
items describing the virtual font) that humans can edit or read. This
program is mostly used by people debugging virtual font utilities.
Synopsis:
vftovp [OPTION]... VFNAME[.vf] [TFMNAME[.tfm] [VPLFILE[.vpl]]]
The fonts VFNAME and TFMNAME (extended with `.vf' and `.tfm' if
necessary) are searched for in the usual places (*note Supported file
formats: (kpathsea)Supported file formats.). To see all the relevant
paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before
running the program. If TFMNAME is not specified, VFNAME (without a
trailing `.vf') is used.
If VPLFILE (extended with `.vpl' if necessary) is not specified, the
property list file is written to standard output. The property list
file can be converted back to VF and TFM format by the companion
program VFtoVP (see the next section).
The program accepts the following option, as well as the standard
`-verbose', `-help' and `-version' (*note Common options::):
`-charcode-format=TYPE'
Output character codes in the PL file according to TYPE: either
`octal' or `ascii'. Default is `ascii' for letters and digits,
octal for all other characters. Exception: if the font's coding
scheme starts with `TeX math sy' or `TeX math ex', all character
codes are output in octal.
In `ascii' format, character codes that correspond to graphic
characters, except for left and right parentheses, are output as a
`C' followed by the single character: `C K', for example. In
octal format, character codes are output as the letter `O' followed
by octal digits, as in `O 113' for `K'.
`octal' format is useful for symbol and other non-alphabetic fonts,
where using ASCII characters for the character codes is merely
confusing.

10.9 VPtoVF: Virtual property lists to virtual font
===================================================
VPtoVF translates a virtual property list file (as output by VFtoVP, for
example) to virtual font (VF, *note Virtual fonts: (dvips)Virtual
fonts.) and TeX font metric (TFM, *note Metric files: (dvips)Metric
files.) files. It's much easier for both programs and humans to create
the (plain text) property list files and let VPtoVF take care of
creating the binary VF and TFM equivalents than to output them
directly. Synopsis:
vptovf [OPTION]... VPLFILE[.vpl] [VFFILE[.vf] [TFMFILE[.tfm]]]
If VFFILE (extended with `.vf' if necessary) is not specified, the
VF output is written to the basename of `VPLFILE.vf'; similarly for
TFMFILE. For example, `vptovf /wherever/ptmr.vpl' creates `./ptmr.vf'
and `./ptmr.tfm'.
The only options are `-verbose', `-help', and `-version' (*note
Common options::).
File: web2c.info, Node: Font utilities available elsewhere, Prev: vptovf invocation, Up: Font utilities
10.10 Font utilities available elsewhere
========================================
The Web2c complement of font utilities merely implements a few basic
conversions. Many other more sophisticated font utilities exist; most
are in `CTAN:/fonts/utilities' (for CTAN info, *note unixtex.ftp:
(kpathsea)unixtex.ftp.). Here are some of the most commonly-requested
items:
* AFM (Adobe font metric) to TFM conversion: *note Invoking afm2tfm:
(dvips)Invoking afm2tfm, and `CTAN:/fonts/utilities/afmtopl'.
* BDF (the X bitmap format) conversion:
`ftp://ftp.tug.org/tex/bdf.tar.gz'.
* Creating fonts using MetaPost: MetaType1.
`ftp://bop.eps.gda.pl/pub/metatype1'. This is used to create the
excellent Latin Modern font family (`CTAN:/fonts/lm'), which
extends Computer Modern to a vast repertoire of scripts.
* Editing of bitmap fonts: Xbfe from the GNU font utilities mentioned
below; the X BDF-editing programs available from
`ftp://ftp.x.org/R5contrib/xfed.tar.Z' and
`ftp://ftp.x.org/R5contrib/xfedor.tar.Z'; and finally, if your
fonts have only 128 characters, you can use the old `gftopxl',
`pxtoch', and `chtopx' programs from `ftp://ftp.tug.org/tex/web'.
* Editing of outline fonts: FontForge, `fontforge.sourceforge.net'.
This is a very elaborate program with support for many outline
formats (Type 1, OpenType, TrueType, ...), and many advanced font
editing features.
* PK bitmaps from PostScript outline fonts: gsftopk from the `xdvi'
distribution. Alternatively, `ps2pk', from
`CTAN:/fonts/utilities/ps2pk'.
* PostScript Type 1 font format conversion (i.e., between PFA and PFB
formats): `http://www.lcdf.org/type'.
* Scanned image conversion: the (aging) GNU font utilities convert
type specimen images to Metafont, PostScript, etc.:
`http://www.gnu.org/software/fontutils/'.
* Tracing bitmaps to fitted outlines: Autotrace
(`http://autotrace.sourceforge.net'), Potrace
(`http://potrace.sourceforge.net'). For Metafont fonts, either of
the two programs `mftrace'
(`http://www.xs4all.nl/~hanwen/mftrace') or `textrace'
(`http://textrace.sourceforge.net') make the job easier.
* Virtual font creation: `CTAN:/fonts/utilities/fontinst'.
