NAME
etex, einitex, evirtex - extended TeX
SYNOPSIS
etex
[options]
[commands]
DESCRIPTION
This manual page is not meant to be exhaustive. The complete
documentation for this version of TeX can be found in the info file
or manual
Web2C: A TeX implementation.
e-TeX 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 TeX, whilst
respecting Knuth's wish that TeX should remain frozen.
e-TeX can be used in two different modes: in
compatibility mode
it is supposed to be completely interchangable with standard TeX.
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
latex.
However,
eplain
is an exception to this rule.
The
einitex
and
evirtex
commands are e-TeX's analogues to the
initex
and
virtex
commands. In this installation, they are symlinks to the
etex
executable.
e-TeX's handling of its command-line arguments is similar to that of
TeX.
OPTIONS
This version of e-TeX understands the following command line options.
--efmt format
Use
format
as the name of the format to be used, instead of the name by which
e-TeX was called or a
%&
line.
--file-line-error-style
Print error messages in the form
file:line:error
which is similar to the way many compilers format them.
--help
Print help message and exit.
--ini
Be
einitex,
for dumping formats; this is implicitly true if the program is called
as
einitex.
--interaction mode
Sets the interaction mode. The mode can be one of
batchmode,
nonstopmode,
scrollmode,
and
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
--ipc,
and starts the server at the other end as well. Whether this option
is available is the choice of the installer.
--jobname name
Use
name
for the job name, instead of deriving it from the name of the input file.
--kpathsea-debug bitmask
Sets path searching debugging flags according to the bitmask. See the
Kpathsea
manual for details.
--maketex fmt
Enable
mktexfmt,
where
fmt
must be one of
tex
or
tfm.
--mltex
Enable MLTeX extensions.
--no-maketex fmt
Disable
mktexfmt,
where
fmt
must be one of
tex
or
tfm.
--output-comment string
Use
string
for the DVI file comment instead of the date.
--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.
--progname name
Pretend to be program
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
.fls.
--shell-escape
Enable the
\write18{command}
construct. The
command
can be any Bourne shell command. This construct is normally
disallowed for security reasons.
--translate-file tcxname
Use the
tcxname
translation table.
--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-TeX formats, you cannot use ~ in a filename you
give directly to e-TeX, because ~ is an active character, and hence is
expanded, not taken as part of the filename. Other programs, such as
Metafont, do not have this problem.
TEXMFOUTPUT
Normally, e-TeX 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
tex paper
and the current directory is not writable, if TEXMFOUTPUT has
the value
/tmp,
e-TeX attempts to create
/tmp/paper.log
(and
/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.
TEXFONTS
Search path for font metric
(.tfm)
files.
TEXFORMATS
Search path for format files.
TEXPOOL
search path for
einitex
internal strings.
TEXEDIT
Command template for switching to editor. The default, usually
vi,
is set when e-TeX is compiled.
FILES
The location of the files mentioned below varies from system to
system. Use the
kpsewhich
utility to find their locations.
etex.pool
Encoded text of e-TeX's messages.
texfonts.map
Filename mapping definitions.
*.tfm
Metric files for e-TeX's fonts.
*.efmt
Predigested e-TeX format (.efmt) files.
BUGS
This version of e-TeX implements a number of optional extensions.
In fact, many of these extensions conflict to a greater or lesser
extent with the definition of e-TeX. When such extensions are
enabled, the banner printed when e-TeX starts is changed to print
e-TeXk
instead of
e-TeX.
This version of e-TeX 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.
