etex
NAME
etex, einitex, evirtex - extended TeX
SYNOPSIS
etex
[options]
[& format ]
[ file | \ commands ]
DESCRIPTION
Run the e- typesetter on
R file ,
usually creating
R file.dvi .
If the file argument has no extension, ".tex" will be appended to it.
Instead of a filename, a set of e- commands can be given, the first
of which must start with a backslash.
With a
I & format
argument e- uses a different set of precompiled commands,
contained in
R format.fmt ;
it is usually better to use the
-fmt
format
option instead.
e- is the first concrete result of an international research &
development project, the NTS Project, which was established under the
aegis of DANTE e.V. during 1992. The aims of the project are to
perpetuate and develop the spirit and philosophy of , whilst
respecting Knuth's wish that should remain frozen.
e- can be used in two different modes: in
compatibility mode
it is supposed to be completely interchangable with standard .
In
extended mode
several new primitives are added that facilitate (among other things)
bidirectional typesetting.
An extended mode format is generated by prefixing the name of the
source file for the format with an asterisk (*). Such formats are
often prefixed with an `e', hence
etex
as the extended version of
tex
and
elatex
as the extended version of
R latex .
However,
eplain
is an exception to this rule.
The
einitex
and
evirtex
commands are e-'s analogues to the
initex
and
virtex
commands. In this installation, they are symbolic links to the
etex
executable. These symbolic links may not exist at all.
e-'s handling of its command-line arguments is similar to that of
the other programs in the
web2c
implementation.
OPTIONS
This version of e- understands the following command line options.
I -fmt format
Use
format
as the name of the format to be used, instead of the name by which
e- was called or a
%&
line.
-enc
Enable the enc extensions. This option is only effective in
combination with
R -ini .
For documentation of the enc extensions see
R http://www.olsak.net/enctex.html .
-etex
Enable the e- extensions. This option is only effective in
combination with
R -ini .
-file-line-error
Print error messages in the form
file:line:error
which is similar to the way many compilers format them.
-no-file-line-error
Disable printing error messages in the
file:line:error
style.
-file-line-error-style
This is the old name of the
-file-line-error
option.
-halt-on-error
Exit with an error code when an error is encountered during processing.
-help
Print help message and exit.
-ini
Start in
INI
mode, which is used to dump formats. The
INI
mode can be used for typesetting, but no format is preloaded, and
basic initializations like setting catcodes may be required.
I -interaction mode
Sets the interaction mode. The mode can be either
R batchmode ,
R nonstopmode ,
R scrollmode ,
and
R errorstopmode .
The meaning of these modes is the same as that of the corresponding
\commands.
-ipc
Send DVI output to a socket as well as the usual output file. Whether
this option is available is the choice of the installer.
-ipc-start
As
R -ipc ,
and starts the server at the other end as well. Whether this option
is available is the choice of the installer.
I -jobname name
Use
name
for the job name, instead of deriving it from the name of the input file.
I -kpathsea-debug bitmask
Sets path searching debugging flags according to the bitmask. See the
Kpathsea
manual for details.
I -mktex fmt
Enable
mktexfmt,
where
fmt
must be either
tex
or
R tfm .
-mltex
Enable ML extensions. Only effective in combination with
R -ini .
I -no-mktex fmt
Disable
mktexfmt,
where
fmt
must be either
tex
or
R tfm .
I -output-comment string
Use
string
for the
DVI
file comment instead of the date.
I -output-directory directory
directory
instead of the current directory. Look up input files in
directory
first, the along the normal search path.
-parse-first-line
If the first line of the main input file begins with
%&
parse it to look for a dump name or a
-translate-file
option.
-no-parse-first-line
Disable parsing of the first line of the main input file.
I -progname name
Pretend to be program
R name .
This affects both the format used and the search paths.
-recorder
Enable the filename recorder. This leaves a trace of the files opened
for input and output in a file with extension
R .fls .
-shell-escape
Enable the
I \write18{ command }
construct. The
command
can be any shell command. This construct is normally
disallowed for security reasons.
-no-shell-escape
Disable the
I \write18{ command }
construct, even if it is enabled in the
texmf.cnf
file.
-src-specials
Insert source specials into the
DVI
file.
I -src-specials where
Insert source specials in certain placed of the
DVI
file.
where
is a comma-separated value list:
R cr ,
R display ,
R hbox ,
R math ,
R par ,
R parent ,
or
R vbox .
I -translate-file tcxname
Use the
tcxname
translation table to set the mapping of input characters and
re-mapping of output characters.
I -default-translate-file tcxname
Like
-translate-file
except that a
%&
line can overrule this setting.
-version
Print version information and exit.
ENVIRONMENT
See the Kpathsearch library documentation (the `Path specifications'
node) for precise details of how the environment variables are used.
The
kpsewhich
utility can be used to query the values of the variables.
One caveat: In most e- formats, you cannot use ~ in a filename you
give directly to e-, because ~ is an active character, and hence is
expanded, not taken as part of the filename. Other programs, such as
, do not have this problem.
TEXMFOUTPUT
Normally, e- puts its output files in the current directory. If
any output file cannot be opened there, it tries to open it in the
directory specified in the environment variable TEXMFOUTPUT.
There is no default value for that variable. For example, if you say
etex paper
and the current directory is not writable, if TEXMFOUTPUT has
the value
R /tmp ,
e- attempts to create
/tmp/paper.log
(and
R /tmp/paper.dvi ,
if any output is produced.)
TEXINPUTS
Search path for
\input
and
\openin
files.
This should probably start with ``.'', so
that user files are found before system files. An empty path
component will be replaced with the paths defined in the
texmf.cnf
file. For example, set TEXINPUTS to ".:/home/usr/tex:" to prepend the
current direcory and ``/home/user/tex'' to the standard search path.
TEXFORMATS
Search path for format files.
TEXPOOL
search path for
etex
internal strings.
TEXEDIT
Command template for switching to editor. The default, usually
R vi ,
is set when e- is compiled.
TFMFONTS
Search path for font metric
(.tfm)
files.
FILES
The location of the files mentioned below varies from system to
system. Use the
kpsewhich
utility to find their locations.
etex.pool
Text file containing e-'s internal strings.
texfonts.map
Filename mapping definitions.
*.tfm
Metric files for e-'s fonts.
*.fmt
Predigested e- format (.fmt) files.
NOTES
Starting with version 1.40, pdf incorporates the e-
extensions, so in this installation e is just a symbolic link to
pdf. See
pdftex(1).
This manual page is not meant to be exhaustive. The complete
documentation for this version of e- can be found in the info
manual
R Web2C: A TeX implementation .
BUGS
This version of e- implements a number of optional extensions.
In fact, many of these extensions conflict to a greater or lesser
extent with the definition of e-. When such extensions are
enabled, the banner printed when e- starts is changed to print
e-TeXk
instead of
R e-TeX .
This version of e- fails to trap arithmetic overflow when
dimensions are added or subtracted. Cases where this occurs are rare,
but when it does the generated
DVI
file will be invalid.

e- was developed by Peter Breitenlohner (and the NTS team).
was designed by Donald E. Knuth,

It was ported to Unix at Stanford by Howard Trickey, and
