17 !!SYNOPSIS
18
19
20 __omega__ [[''options''] [[''commands'']
21 !!DESCRIPTION
22
23
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''.
28
29
30 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.
47 !!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
199
200 TEXEDIT
201
202
203 Command template for switching to editor. The default,
204 usually __vi__, is set when Omega is
205 compiled.
206 !!FILES
207
208
209 The location of the files mentioned below varies from system
210 to system. Use the __kpsewhich__ utility to find their
211 locations.
212
213
214 ''omega.pool''
215
216
217 Encoded text of Omega's messages.
218
219
220 ''*.fmt''
221
222
223 Predigested Omega format (.fmt) files.
224 !!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,
236 you should use __odvips__ to generate a !PostScript
237 file.
238
239
240 Omega is experimental software. If you use it, subscribe to
241 the omega mailing list __omega@ens.fr__ by sending a
242 message containing __subscribe omega__ ''Your Name''
243 to __listserv@ens.fr__.
