1.24 kristaps 70: to print warnings,
1.58 kristaps 71: .Fl W Ns Cm error
1.24 kristaps 72: for warnings to be considered errors and cause utility
1.57 kristaps 73: termination.
74: Multiple

1.8 kristaps 99: .Ss Input Formats
100: The

1.8 kristaps 108: and
1.58 kristaps 109: .Fl m Ns Cm an ,
1.57 kristaps 110: respectively.
111: The
1.8 kristaps 112: .Xr mdoc 7
113: format is
114: .Em strongly
1.26 kristaps 115: recommended;
1.8 kristaps 116: .Xr man 7
117: should only be used for legacy manuals.
1.11 kristaps 118: .Pp
1.12 kristaps 119: A third option,
1.58 kristaps 120: .Fl m Ns Cm andoc ,
1.13 kristaps 121: which is also the default, determines encoding on-the-fly: if the first

1.27 kristaps 123: .Sq \&Dd
1.13 kristaps 124: or
1.27 kristaps 125: .Sq \&Dt ,
1.26 kristaps 126: the
1.13 kristaps 127: .Xr mdoc 7
128: parser is used; otherwise, the

130: parser is used.
131: .Pp
132: If multiple
1.26 kristaps 133: files are specified with
1.58 kristaps 134: .Fl m Ns Cm andoc ,
1.57 kristaps 135: each has its file-type determined this way.
136: If multiple files are

1.12 kristaps 139: or
1.58 kristaps 140: .Fl m Ns Cm an
1.12 kristaps 141: is specified, then this format is used exclusively.
1.1 kristaps 142: .Ss Output Formats

1.19 kristaps 180: .Bl -tag -width Ds
1.58 kristaps 181: .It Fl f Ns Cm ign-errors

190: .It Fl f Ns Cm ign-scope
1.1 kristaps 191: When rewinding the scope of a block macro, forces the compiler to ignore
1.57 kristaps 192: scope violations.

214: .Ar fmt ,
1.49 kristaps 215: for example,
1.40 kristaps 216: .Ar ../src/%I.html ,
217: is used as a template for linked header files (usually via the

1.57 kristaps 219: macro).
220: Instances of
1.43 kristaps 221: .Sq \&%I
1.57 kristaps 222: are replaced with the include filename.
223: The default is not to present a

1.58 kristaps 225: .It Fl O Ns Cm man Ns = Ns Ar fmt
1.39 kristaps 226: The string
227: .Ar fmt ,
1.49 kristaps 228: for example,
1.39 kristaps 229: .Ar ../html%S/%N.%S.html ,
230: is used as a template for linked manuals (usually via the

1.57 kristaps 232: macro).
233: Instances of
1.43 kristaps 234: .Sq \&%N

237: are replaced with the linked manual's name and section, respectively.
1.57 kristaps 238: If no section is included, section 1 is assumed.

1.48 kristaps 248: .Sh OUTPUT
249: This section documents output details of
250: .Nm .
251: In general, output conforms to the traditional manual style of a header,
1.49 kristaps 252: a body composed of sections and sub-sections, and a footer.
1.48 kristaps 253: .Pp
254: The text style of output characters (non-macro characters, punctuation,
255: and white-space) is dictated by context.
256: .Pp
1.57 kristaps 257: White-space is generally stripped from input.
258: This can be changed with
1.48 kristaps 259: character escapes (specified in
260: .Xr mandoc_char 7 )
261: or literal modes (specified in
262: .Xr mdoc 7
263: and
264: .Xr man 7 ) .
265: .Pp
266: If non-macro punctuation is set apart from words, such as in the phrase
267: .Dq to be \&, or not to be ,
268: it's processed by
269: .Nm ,
270: regardless of output format, according to the following rules: opening
271: punctuation
272: .Po
273: .Sq \&( ,
274: .Sq \&[ ,
275: and
276: .Sq \&{
277: .Pc
278: is not followed by a space; closing punctuation
279: .Po
280: .Sq \&. ,
281: .Sq \&, ,
282: .Sq \&; ,
283: .Sq \&: ,
284: .Sq \&? ,
285: .Sq \&! ,
286: .Sq \&) ,
287: .Sq \&]
288: and
289: .Sq \&}
290: .Pc
291: is not preceded by white-space.
292: .Pp
293: If the input is
294: .Xr mdoc 7 ,
295: however, these rules are also applied to macro arguments when appropriate.
296: .Ss ASCII Output
1.49 kristaps 297: Output produced by
1.58 kristaps 298: .Fl T Ns Cm ascii ,
1.48 kristaps 299: which is the default, is rendered in standard 7-bit ASCII documented in
300: .Xr ascii 7 .
301: .Pp
302: Font styles are applied by using back-spaced encoding such that an
303: underlined character
304: .Sq c
305: is rendered as
306: .Sq _ Ns \e[bs] Ns c ,
307: where
308: .Sq \e[bs]
1.57 kristaps 309: is the back-space character number 8.
310: Emboldened characters are rendered as
1.48 kristaps 311: .Sq c Ns \e[bs] Ns c .
312: .Pp
313: The special characters documented in
314: .Xr mandoc_char 7
315: are rendered best-effort in an ASCII equivalent.
316: .Pp
317: Output width is limited to 78 visible columns unless literal input lines
318: exceed this limit.
319: .Ss HTML Output
320: Output produced by
1.58 kristaps 321: .Fl T Ns Cm html
1.50 kristaps 322: conforms to HTML-4.01 strict.
1.48 kristaps 323: .Pp
1.57 kristaps 324: Font styles and page structure are applied using CSS2.
325: By default, no font style is applied to any text,
326: although CSS2 is hard-coded to format
1.48 kristaps 327: the basic structure of output.
328: .Pp
329: The
330: .Pa example.style.css
331: file documents the range of styles applied to output and, if used, will
332: cause rendered documents to appear as they do in
1.58 kristaps 333: .Fl T Ns Cm ascii .
1.48 kristaps 334: .Pp
335: Special characters are rendered in decimal-encoded UTF-8.
1.50 kristaps 336: .Ss XHTML Output
337: Output produced by
1.58 kristaps 338: .Fl T Ns Cm xhtml
1.50 kristaps 339: conforms to XHTML-1.0 strict.
340: .Pp
341: See
342: .Sx HTML Output
343: for details; beyond generating XHTML tags instead of HTML tags, these
344: output modes are identical.
1.1 kristaps 345: .Sh EXAMPLES
1.13 kristaps 346: To page manuals to the terminal:

1.20 kristaps 409: .It
410: Words aren't hyphenated.
1.22 kristaps 411: .It
412: In normal mode (not a literal block), blocks of spaces aren't preserved,
