etex, einitex, evirtex - extended TeX
etex [options]
[commands]
This manual page is not meant to be exhaustive.
The complete documentation for this version of can be found in the info
file or manual Web2C: A TeX implementation.
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 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 symlinks to the etex executable.
e-'s handling
of its command-line arguments is similar to that of .
This version
of e- understands the following command line options.
- --default-translate-file tcxname
- Use the default tcxname translation table. The --translate-file can overwrite
this setting.
- --efmt 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 enc extension
by Petr Olsak, see the file encdoc-e.pdf.
- --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 ML 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.
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 tex paper and the current directory is not writable,
if TEXMFOUTPUT has the value /tmp, e- 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- is compiled.
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-'s messages.
- texfonts.map
- Filename mapping
definitions.
- *.tfm
- Metric files for e-'s fonts.
- *.efmt
- Predigested e- format (.efmt)
files.
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 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.
