omega, iniomega, viromega - extended unicode TeX
omega [options] [commands]

to be exhaustive. The complete documentation for this version of can
be found in the info file or manual Web2C: A TeX implementation.
Omega
is a version of the program modified for multilingual typesetting. It
uses unicode, and has additional primitives for (among other things) bidirectional
typesetting.
The iniomega and viromega commands are Omega's analogues to
the initex and virtex commands. In this installation, they are symlinks
to the omega executable.
Omega's command line options are similar to those
of .
Omega is experimental software.
This version of Omega understands
the following command line options.
- --fmt format
- Use format as the name
of the format to be used, instead of the name by which Omega was called
or a %& line.
- --help
- Print help message and exit.
- --ini
- Be iniomega, for
dumping formats; this is implicitly true if the program is called as iniomega.
- --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.
- --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.
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 Omega formats, you cannot use ~ in a filename you give directly to
Omega, 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, Omega 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,
Omega 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.
- TEXEDIT
- Command template for switching to editor. The default, usually vi, is
set when Omega is compiled.
The location of the files mentioned
below varies from system to system. Use the kpsewhich utility to find
their locations.
- omega.pool
- Encoded text of Omega's messages.
- *.fmt
- Predigested
Omega format (.fmt) files.
This version of Omega 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.
The DVI files produced by
Omega may use extensions which make them incompatible with most software
designed to handle DVI files. In order to print or preview them, you should
use odvips to generate a PostScript file.
Omega is experimental software.
