NAME
omega, iniomega, viromega - extended unicode TeX
SYNOPSIS
omega
[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.
Omega is a version of the TeX 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 TeX.
Omega is experimental software.
OPTIONS
This version of Omega understands the following command line options.
--oft 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.
--parse-first-line
If the first line of the main input file begins with
%&
parse it to look for a dump name.
--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
.ofl.
(This option is always on.)
--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 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
Metafont, 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.
FILES
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.
*.oft
Predigested Omega format (.oft) files.
BUGS
This version of Omega implements a number of optional extensions.
In fact, many of these extensions conflict to a greater or lesser
extent with the definition of Omega. When such extensions are
enabled, the banner printed when Omega starts is changed to print
Omegak
instead of
Omega.
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, and if you are an active user it is
strongly recommended that you subscribe to the Omega mailing list.
