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.
- --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.
- --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.
- --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.
- --recorder
- Enable
the filename recorder. This leaves a trace of the files opened for input
and output in a file with extension .fls.
- --progname name
- Pretend to be program
name. This affects both the format used and the search paths.
- --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- 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.
