SYNOPSIS

etex [options] [commands]

DESCRIPTION

This manual page is not meant to be exhaustive. The complete documentation for this version of T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X can be found in the info file or manual Web2C: A TeX implementation.

e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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 T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X, whilst respecting Knuth’s wish that T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X should remain frozen.

e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X can be used in two different modes: in compatibility mode it is supposed to be completely interchangable with standard T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X. 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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X’s analogues to the initex and virtex commands. In this installation, they are symlinks to the etex executable.

e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X’s handling of its command-line arguments is similar to that of T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X.

OPTIONS

This version of e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X was called or a %& line.
--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 MLT\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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.
--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.
--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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X formats, you cannot use ~ in a filename you give directly to e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X, 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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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.
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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X’s messages.
texfonts.map
  Filename mapping definitions.
*.tfm Metric files for e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X’s fonts.
*.efmt Predigested e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X format (.efmt) files.

BUGS

This version of e-T\h’-0.1667m’\v’0.20v’E\v’-0.20v’\h’-0.125m’X 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.
