1 \C{running} Running Halibut
2
3 \I{running Halibut}In the simplest case, running Halibut is very
4 simple. You provide a set of input files on its \i{command line},
5 and it produces a set of output files.
6
7 \c $ halibut intro.but getting-started.but reference.but index.but
8 \e bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
9
10 This will generate a large set of \i{output files}:
11
12 \b \i\c{output.txt} will be a \i{plain text} version of the input
13 document.
14
15 \b \i\c{output.hlp} and \i\c{output.cnt} will be a \i{Windows Help}
16 version of the same thing. (Most of the text is in \c{output.hlp};
17 \c{output.cnt} contains additional contents data used by the Windows
18 help topic selector. If you lose the latter, the former should still
19 be usable, but it will look less modern.)
20
21 \lcont{
22 Note that Halibut does not require any external software such as a
23 \i{Help compiler}. It \e{directly} generates Windows Help files, and
24 therefore it doesn't need to be run on Windows to do so: it can
25 generate them even when run from an automated script on a Unix
26 machine.
27 }
28
29 \b \c{output.1} will be a Unix \i{\cw{man} page}.
30
31 \b The set of files \c{*.html} will contain an \i{HTML} version of
32 the document. If you have configured Halibut to generate more than
33 one HTML file (the default), then the file \c{Contents.html} will be
34 the topmost one that users should be directed to initially. If you
35 have configured Halibut to generate a single file, it will be called
36 \c{Manual.html}.
37
38 \b \c{output.info}, and some additional files \c{output.info-1},
39 \c{output.info-2} etc., will be files suitable for use with GNU
40 \c{info}.
41
42 \H{running-options} \ii{Command-line options}
43
44 Halibut supports command-line options in case you don't want to use
45 all of Halibut's \i{output formats}, or you want to configure the
46 names of your \i{output files}, or you want to supply additional
47 configuration on the command line. The supported options are listed
48 here.
49
50 Firstly, there are options which indicate which of the output
51 formats you want Halibut to generate:
52
53 \dt \i\cw{--text}[\cw{=}\e{filename}]
54
55 \dd Specifies that you want to generate plain text output. You can
56 optionally specify a file name (e.g. \c{--text=myfile.txt}), in
57 which case Halibut will change the name of the output file as well.
58
59 \dt \i\cw{--html}[\cw{=}\e{filename}]
60
61 \dd Specifies that you want to generate HTML output. You can
62 optionally specify a file name (e.g. \c{--html=myfile.html}), in
63 which case Halibut will change the name of the output file as well.
64 Specifying a file name here will also cause the HTML to be output in
65 \e{only} one file, instead of the usual behaviour of producing
66 multiple files with links between them. If you want to produce
67 multiple files and configure their names, you will need to use the
68 more complete file name configuration directives given in
69 \k{output-html-file} (although you may want to do so on the command
70 line, using the \c{-C} option).
71
72 \dt \i\cw{--xhtml}[\cw{=}\e{filename}]
73
74 \dd Synonym for \c{--html}.
75
76 \dt \i\cw{--winhelp}[\cw{=}\e{filename}]
77
78 \dd Specifies that you want to generate Windows Help output. You can
79 optionally specify a file name (e.g. \c{--winhelp=myfile.hlp}), in
80 which case Halibut will change the name of the output file as well.
81
82 \lcont{
83
84 Your output file name should end with \c{.hlp}; if it doesn't,
85 Halibut will append it. Halibut will also generate a contents file
86 (ending in \c{.cnt}) alongside the file name you specify.
87
88 }
89
90 \dt \i\cw{--whlp}[\cw{=}\e{filename}]
91
92 \dd Synonym for \c{--winhelp}.
93
94 \dt \i\cw{--hlp}[\cw{=}\e{filename}]
95
96 \dd Synonym for \c{--winhelp}.
97
98 \dt \i\cw{--man}[\cw{=}\e{filename}]
99
100 \dd Specifies that you want to generate \cw{man} page output. You
101 can optionally specify a file name (e.g. \c{--man=myfile.5}), in
102 which case Halibut will change the name of the output file as well.
103
104 \dt \i\cw{--info}[\cw{=}\e{filename}]
105
106 \dd Specifies that you want to generate GNU \c{info} output. You can
107 optionally specify a file name (e.g. \c{--info=myfile.info}), in
108 which case Halibut will change the name of the output file as well.
109
110 \lcont{
111
112 Unless the \c{info} output format is configured not to (see
113 \k{output-info}), Halibut will divide the \c{info} output into many
114 small files. The extra files will have numeric suffixes on their
115 names; so, for example, \c{output.info} might be accompanied by
116 additional files \c{output.info-1}, \c{output.info-2} and so on.
117
118 }
119
120 If you do not specify any of the above options, Halibut will simply
121 produce \e{all} of its output formats.
122
123 Also, there is an option which allows you to specify an arbitrary
124 \i\c{\\cfg} configuration directive (see \k{input-config}):
125
126 \dt \i\cw{-C}\e{config-directive}\cw{:}\e{value}[\cw{:}\e{value}...]
127
128 \dd The text following \c{-C} is expected to be a colon-separated
129 list of strings. (If you need a literal colon, you can escape it
130 with a backslash: \c{\\:}. If you need a literal \e{backslash}, you
131 can do the same: \c{\\\\}.) These strings are used as the parts of a
132 \c{\\cfg} directive. So, for example, the option
133
134 \lcont{
135
136 \c -Ctext-section-align:2:leftplus
137
138 will translate into the configuration directive
139
140 \c \cfg{text-section-align}{2}{leftplus}
141
142 }
143
144 The options which set the output file names actually work by
145 implicitly generating these configuration directives. When you
146 specify \c{--text=myfile.txt}, for example, Halibut treats it
147 identically to \c{--text -Ctext-filename:myfile.txt}. The Windows
148 Help and man page formats work similarly. HTML is slightly
149 different, since it also arranges for single-file output if you pass
150 a filename to \c{--html}; so \c{--html=myfile.html} is equivalent to
151 \c{--html -Cxhtml-single-filename:myfile.html -Cxhtml-leaf-level:0}.
152 (See \k{output} for explanations of all these configuration
153 directives.)
154
155 In addition to these, there are also a few other options:
156
157 \dt \i\cw{--help}
158
159 \dd Print a brief help message and exit immediately. (Don't confuse
160 this with \c{--winhelp}!)
161
162 \dt \i\cw{--version}
163
164 \dd Print information about Halibut's version number and exit
165 immediately.
166
167 \dt \i\cw{--licence}
168
169 \dd Display Halibut's licence (see also \k{licence}) and exit
170 immediately.
171
172 \dt \cw{--license}
173
174 \dd US English alternative spelling of \c{--licence}.
175
176 \dt \i\cw{--precise}
177
178 \dd Report column numbers as well as line numbers when reporting
179 errors in the Halibut input files.
