!!DESCRIPTION |

|
|
|
24 |
This manual page is not meant to be exhaustive. The complete |
|
|
25 |
documentation for this version of TEX can be found in the |
|
|
26 |
info file or manual ''Web2C: A TeX |
|
|
27 |
implementation''. |

Omega is a version of the TEX program modified for |
|
|
31 |
multilingual typesetting. It uses unicode, and has |
|
|
32 |
additional primitives for (among other things) bidirectional |
|
|
33 |
typesetting. |
|
|
34 |
|
|
|
35 |
|
|
|
36 |
The __iniomega__ and __viromega__ commands are Omega's |
|
|
37 |
analogues to the __initex__ and __virtex__ commands. |
|
|
38 |
In this installation, they are symlinks to the __omega__ |
|
|
39 |
executable. |
|
|
40 |
|
|
|
41 |
|
|
|
42 |
Omega's command line options are similar to those of |
|
|
43 |
TEX. |
|
|
44 |
|
|
|
45 |
|
|
|
46 |
Omega is experimental software. |
|
|

!!OPTIONS |
|
|
48 |
|
|
|
49 |
|
|
|
50 |
This version of Omega understands the following command line |
|
|
51 |
options. |
|
|
52 |
|
|
|
53 |
|
|
|
54 |
__--fmt__ ''format'' |
|
|
55 |
|
|
|
56 |
|
|
|
57 |
Use ''format'' as the name of the format to be used, |
|
|
58 |
instead of the name by which Omega was called or a |
|
|
59 |
''%'' line. |
|
|
60 |
|
|
|
61 |
|
|
|
62 |
__--help__ |
|
|
63 |
|
|
|
64 |
|
|
|
65 |
Print help message and exit. |
|
|
66 |
|
|
|
67 |
|
|
|
68 |
__--ini__ |
|
|
69 |
|
|
|
70 |
|
|
|
71 |
Be __iniomega__, for dumping formats; this is implicitly |
|
|
72 |
true if the program is called as |
|
|
73 |
__iniomega__. |
|
|
74 |
|
|
|
75 |
|
|
|
76 |
__--interaction__ ''mode'' |
|
|
77 |
|
|
|
78 |
|
|
|
79 |
Sets the interaction mode. The mode can be one of |
|
|
80 |
''batchmode'', ''nonstopmode'', ''scrollmode'', and |
|
|
81 |
''errorstopmode''. The meaning of these modes is the same |
|
|
82 |
as that of the corresponding commands. |
|
|
83 |
|
|
|
84 |
|
|
|
85 |
__--ipc__ |
|
|
86 |
|
|
|
87 |
|
|
|
88 |
Send DVI output to a socket as well as the usual output |
|
|
89 |
file. Whether this option is available is the choice of the |
|
|
90 |
installer. |
|
|
91 |
|
|
|
92 |
|
|
|
93 |
__--ipc-start__ |
|
|
94 |
|
|
|
95 |
|
|
|
96 |
As __--ipc__, and starts the server at the other end as |
|
|
97 |
well. Whether this option is available is the choice of the |
|
|
98 |
installer. |
|
|
99 |
|
|
|
100 |
|
|
|
101 |
__--kpathsea-debug__ ''bitmask'' |
|
|
102 |
|
|
|
103 |
|
|
|
104 |
Sets path searching debugging flags according to the |
|
|
105 |
bitmask. See the ''Kpathsea'' manual for |
|
|
106 |
details. |
|
|
107 |
|
|
|
108 |
|
|
|
109 |
__--maketex__ ''fmt'' |
|
|
110 |
|
|
|
111 |
|
|
|
112 |
Enable mktex''fmt'', where ''fmt'' must be one of |
|
|
113 |
''tex'' or ''tfm''. |
|
|
114 |
|
|
|
115 |
|
|
|
116 |
__--no-maketex__ ''fmt'' |
|
|
117 |
|
|
|
118 |
|
|
|
119 |
Disable mktex''fmt'', where ''fmt'' must be one of |
|
|
120 |
''tex'' or ''tfm''. |
|
|
121 |
|
|
|
122 |
|
|
|
123 |
__--output-comment__ ''string'' |
|
|
124 |
|
|
|
125 |
|
|
|
126 |
Use ''string'' for the DVI file comment instead of the |
|
|
127 |
date. |
|
|
128 |
|
|
|
129 |
|
|
|
130 |
__--progname__ ''name'' |
|
|
131 |
|
|
|
132 |
|
|
|
133 |
Pretend to be program ''name''. This affects both the |
|
|
134 |
format used and the search paths. |
|
|
135 |
|
|
|
136 |
|
|
|
137 |
__--recorder__ |
|
|
138 |
|
|
|
139 |
|
|
|
140 |
Enable the filename recorder. This leaves a trace of the |
|
|
141 |
files opened for input and output in a file with extension |
|
|
142 |
''.ofl''. (This option is always on.) |
|
|
143 |
|
|
|
144 |
|
|
|
145 |
__--shell-escape__ |
|
|
146 |
|
|
|
147 |
|
|
|
148 |
Enable the __write18{__''command''__}__ construct. |
|
|
149 |
The ''command'' can be any Bourne shell command. This |
|
|
150 |
construct is normally disallowed for security |
|
|
151 |
reasons. |
|
|
152 |
|
|
|
153 |
|
|
|
154 |
__--version__ |
|
|
155 |
|
|
|
156 |
|
|
|
157 |
Print version information and exit. |
|
|
158 |
!!ENVIRONMENT |
|
|
159 |
|
|
|
160 |
|
|
|
161 |
See the Kpathsearch library documentation (the `Path |
|
|
162 |
specifications' node) for precise details of how the |
|
|
163 |
environment variables are used. The __kpsewhich__ utility |
|
|
164 |
can be used to query the values of the |
|
|
165 |
variables. |
|
|
166 |
|
|
|
167 |
|
|
|
168 |
One caveat: In most Omega formats, you cannot use ~ in a |
|
|
169 |
filename you give directly to Omega, because ~ is an active |
|
|
170 |
character, and hence is expanded, not taken as part of the |
|
|
171 |
filename. Other programs, such as M ETAFONT , |
|
|
172 |
do not have this problem. |
|
|
173 |
|
|
|
174 |
|
|
|
175 |
TEXMFOUTPUT |
|
|
176 |
|
|
|
177 |
|
|
|
178 |
Normally, Omega puts its output files in the current |
|
|
179 |
directory. If any output file cannot be opened there, it |
|
|
180 |
tries to open it in the directory specified in the |
|
|
181 |
environment variable TEXMFOUTPUT. There is no default value |
|
|
182 |
for that variable. For example, if you say ''tex paper'' |
|
|
183 |
and the current directory is not writable, if TEXMFOUTPUT |
|
|
184 |
has the value ''/tmp'', Omega attempts to create |
|
|
185 |
''/tmp/paper.log'' (and ''/tmp/paper.dvi'', if any |
|
|
186 |
output is produced.) |
|
|
187 |
|
|
|
188 |
|
|
|
189 |
TEXINPUTS |
|
|
190 |
|
|
|
191 |
|
|
|
192 |
Search path for ''input'' and ''openin'' files. This |
|
|
193 |
should probably start with ``.'', so that user files are |
|
|
194 |
found before system files. An empty path component will be |
|
|
195 |
replaced with the paths defined in the ''texmf.cnf'' |
|
|
196 |
file. For example, set TEXINPUTS to |
|
|
197 |
'' |
|
|
198 |

|

TEXEDIT |
|
|
201 |
|
|
|
202 |
|
|
|
203 |
Command template for switching to editor. The default, |
|
|
204 |
usually __vi__, is set when Omega is |
|
|
205 |
compiled. |

!!BUGS |
|
|
225 |
|
|
|
226 |
|
|
|
227 |
This version of Omega fails to trap arithmetic overflow when |
|
|
228 |
dimensions are added or subtracted. Cases where this occurs |
|
|
229 |
are rare, but when it does the generated ''DVI'' file |
|
|
230 |
will be invalid. |
|
|
231 |
|
|
|
232 |
|
|
|
233 |
The ''DVI'' files produced by Omega may use extensions |
|
|
234 |
which make them incompatible with most software designed to |
|
|
235 |
handle ''DVI'' files. In order to print or preview them, |
2 |
perry |
236 |
you should use __odvips__ to generate a !PostScript |
1 |
perry |
237 |
file. |
