1.8 schwarze 66: Configure warning messages. Use
1.1 kristaps 67: .Fl W Ns Ar all
1.8 schwarze 68: to print warnings,
1.10 schwarze 69: .Fl W Ns Ar error
1.8 schwarze 70: for warnings to be considered errors and cause utility
1.10 schwarze 71: termination. Multiple

74: .Fl W Ns Ar error,all .

82: .El

91: text from stdin, implying
92: .Fl m Ns Ar andoc ,
93: and prints 78-column backspace-encoded output to stdout as if

1.7 schwarze 101: .Ss Punctuation and Spacing
1.1 kristaps 102: If punctuation is set apart from words, such as in the phrase
103: .Dq to be \&, or not to be ,
104: it's processed by
105: .Nm
1.7 schwarze 106: according to the following rules: opening punctuation
1.1 kristaps 107: .Po
1.10 schwarze 108: .Sq \&( ,
109: .Sq \&[ ,
1.1 kristaps 110: and
111: .Sq \&{
1.10 schwarze 112: .Pc
1.7 schwarze 113: is not followed by a space; closing punctuation
1.1 kristaps 114: .Po
1.10 schwarze 115: .Sq \&. ,
116: .Sq \&, ,
117: .Sq \&; ,
118: .Sq \&: ,
119: .Sq \&? ,
120: .Sq \&! ,
121: .Sq \&) ,
122: .Sq \&]
1.1 kristaps 123: and
124: .Sq \&}
1.10 schwarze 125: .Pc
1.3 schwarze 126: is not preceded by whitespace.
1.14 schwarze 127: .
1.1 kristaps 128: .Pp
129: If the input is
130: .Xr mdoc 7 ,
131: these rules are also applied to macro arguments when appropriate.
1.14 schwarze 132: .
1.7 schwarze 133: .Pp
134: White-space, in non-literal (normal) mode, is stripped from input and
1.14 schwarze 135: replaced on output by a single space. Thus, if you wish to preserve multiple
136: spaces, they must be space-escaped or used in a literal display mode, e.g.,
1.11 schwarze 137: .Sq \&Bd \-literal
1.10 schwarze 138: in
1.7 schwarze 139: .Xr mdoc 7 .
1.14 schwarze 140: .
141: .
1.1 kristaps 142: .Ss Input Formats
143: The
144: .Nm
145: utility accepts
146: .Xr mdoc 7
147: and
148: .Xr man 7
149: input with
150: .Fl m Ns Ar doc
151: and
152: .Fl m Ns Ar an ,
153: respectively. The
154: .Xr mdoc 7
155: format is
156: .Em strongly
1.10 schwarze 157: recommended;
1.1 kristaps 158: .Xr man 7
159: should only be used for legacy manuals.
1.14 schwarze 160: .
1.1 kristaps 161: .Pp
162: A third option,
163: .Fl m Ns Ar andoc ,
164: which is also the default, determines encoding on-the-fly: if the first
1.10 schwarze 165: non-comment macro is
1.11 schwarze 166: .Sq \&Dd
1.1 kristaps 167: or
1.11 schwarze 168: .Sq \&Dt ,
1.10 schwarze 169: the
1.1 kristaps 170: .Xr mdoc 7
171: parser is used; otherwise, the
172: .Xr man 7
173: parser is used.
1.14 schwarze 174: .
1.1 kristaps 175: .Pp
176: If multiple
1.10 schwarze 177: files are specified with
178: .Fl m Ns Ar andoc ,
1.1 kristaps 179: each has its file-type determined this way. If multiple files are
180: specified and
181: .Fl m Ns Ar doc
182: or
183: .Fl m Ns Ar an
184: is specified, then this format is used exclusively.
1.14 schwarze 185: .
186: .
1.1 kristaps 187: .Ss Output Formats
188: The
189: .Nm
190: utility accepts the following
191: .Fl T
192: arguments:
1.14 schwarze 193: .
1.5 schwarze 194: .Bl -tag -width Ds
1.1 kristaps 195: .It Fl T Ns Ar ascii
196: Produce 7-bit ASCII output, backspace-encoded for bold and underline
197: styles. This is the default.
1.14 schwarze 198: .
1.1 kristaps 199: .It Fl T Ns Ar tree
200: Produce an indented parse tree.
1.14 schwarze 201: .
1.1 kristaps 202: .It Fl T Ns Ar lint
203: Parse only: produce no output.
204: .El
1.14 schwarze 205: .
1.1 kristaps 206: .Pp
207: If multiple input files are specified, these will be processed by the
208: corresponding filter in-order.
1.14 schwarze 209: .
210: .
1.1 kristaps 211: .Ss Compiler Options
1.15 schwarze 212: Default compiler behaviour may be overridden with the
1.1 kristaps 213: .Fl f
214: flag.
1.14 schwarze 215: .
1.5 schwarze 216: .Bl -tag -width Ds
1.1 kristaps 217: .It Fl f Ns Ar ign-scope
218: When rewinding the scope of a block macro, forces the compiler to ignore
219: scope violations. This can seriously mangle the resulting tree.
220: .Pq mdoc only
1.14 schwarze 221: .
1.1 kristaps 222: .It Fl f Ns Ar no-ign-escape
223: Don't ignore invalid escape sequences.
1.14 schwarze 224: .
1.1 kristaps 225: .It Fl f Ns Ar no-ign-macro
226: Do not ignore unknown macros at the start of input lines.
1.14 schwarze 227: .
1.1 kristaps 228: .It Fl f Ns Ar no-ign-chars
229: Do not ignore disallowed characters.
1.14 schwarze 230: .
1.1 kristaps 231: .It Fl f Ns Ar strict
1.10 schwarze 232: Implies
1.1 kristaps 233: .Fl f Ns Ar no-ign-escape ,
1.10 schwarze 234: .Fl f Ns Ar no-ign-macro
1.1 kristaps 235: and
1.10 schwarze 236: .Fl f Ns Ar no-ign-chars .
1.14 schwarze 237: .
1.12 schwarze 238: .It Fl f Ns Ar ign-errors
239: Don't halt when encountering parse errors. Useful with
240: .Fl T Ns Ar lint
241: over a large set of manuals passed on the command line.
1.1 kristaps 242: .El
1.14 schwarze 243: .
1.1 kristaps 244: .Pp
245: As with the
246: .Fl W
247: flag, multiple
248: .Fl f
249: options may be grouped and delimited with a comma. Using
250: .Fl f Ns Ar ign-scope,no-ign-escape ,
251: for example, will try to ignore scope and not ignore character-escape
252: errors.

1.1 kristaps 255: .Sh EXAMPLES
256: To page manuals to the terminal:

325: Words aren't hyphenated.
1.14 schwarze 326: .
1.7 schwarze 327: .It
328: In normal mode (not a literal block), blocks of spaces aren't preserved,
