1.26 jmc 71: .Fl W Ns Cm error
1.8 schwarze 72: for warnings to be considered errors and cause utility

1.25 jmc 110: respectively.
111: The
1.1 kristaps 112: .Xr mdoc 7
113: format is
114: .Em strongly
1.10 schwarze 115: recommended;
1.1 kristaps 116: .Xr man 7

118: .Pp
119: A third option,
1.26 jmc 120: .Fl m Ns Cm andoc ,
1.1 kristaps 121: which is also the default, determines encoding on-the-fly: if the first

1.11 schwarze 123: .Sq \&Dd
1.1 kristaps 124: or
1.11 schwarze 125: .Sq \&Dt ,
1.10 schwarze 126: the

132: If multiple
1.10 schwarze 133: files are specified with
1.26 jmc 134: .Fl m Ns Cm andoc ,
1.25 jmc 135: each has its file-type determined this way.

1.1 kristaps 139: or

194: .It Fl f Ns Cm ign-scope
1.1 kristaps 195: When rewinding the scope of a block macro, forces the compiler to ignore

1.21 schwarze 221: for example,
1.17 schwarze 222: .Ar ../src/%I.html ,
223: is used as a template for linked header files (usually via the

226: Instances of

239: Instances of

1.25 jmc 244: If no section is included, section 1 is assumed.

1.17 schwarze 265: .El
1.20 schwarze 266: .Sh OUTPUT
267: This section documents output details of
268: .Nm .
269: In general, output conforms to the traditional manual style of a header,
1.21 schwarze 270: a body composed of sections and sub-sections, and a footer.
1.20 schwarze 271: .Pp
272: The text style of output characters (non-macro characters, punctuation,
273: and white-space) is dictated by context.
274: .Pp
1.25 jmc 275: White-space is generally stripped from input.
276: This can be changed with
1.20 schwarze 277: character escapes (specified in
278: .Xr mandoc_char 7 )
279: or literal modes (specified in
280: .Xr mdoc 7
281: and
282: .Xr man 7 ) .
283: .Pp
284: If non-macro punctuation is set apart from words, such as in the phrase
285: .Dq to be \&, or not to be ,
286: it's processed by
287: .Nm ,
288: regardless of output format, according to the following rules: opening
289: punctuation
290: .Po
291: .Sq \&( ,
292: .Sq \&[ ,

306: and

308: .Pc
309: is not preceded by white-space.
310: .Pp
311: If the input is
312: .Xr mdoc 7 ,
313: however, these rules are also applied to macro arguments when appropriate.
314: .Ss ASCII Output
1.21 schwarze 315: Output produced by
1.26 jmc 316: .Fl T Ns Cm ascii ,
1.20 schwarze 317: which is the default, is rendered in standard 7-bit ASCII documented in
318: .Xr ascii 7 .
319: .Pp
320: Font styles are applied by using back-spaced encoding such that an
321: underlined character
322: .Sq c
323: is rendered as
324: .Sq _ Ns \e[bs] Ns c ,
325: where
326: .Sq \e[bs]
1.25 jmc 327: is the back-space character number 8.
328: Emboldened characters are rendered as
1.20 schwarze 329: .Sq c Ns \e[bs] Ns c .
330: .Pp
331: The special characters documented in
332: .Xr mandoc_char 7
333: are rendered best-effort in an ASCII equivalent.
334: .Pp
335: Output width is limited to 78 visible columns unless literal input lines
336: exceed this limit.
337: .Ss HTML Output
338: Output produced by
1.26 jmc 339: .Fl T Ns Cm html
1.21 schwarze 340: conforms to HTML-4.01 strict.
1.20 schwarze 341: .Pp
1.25 jmc 342: Font styles and page structure are applied using CSS2.
343: By default, no font style is applied to any text,
344: although CSS2 is hard-coded to format
1.20 schwarze 345: the basic structure of output.
346: .Pp
347: The
348: .Pa example.style.css
349: file documents the range of styles applied to output and, if used, will
350: cause rendered documents to appear as they do in
1.26 jmc 351: .Fl T Ns Cm ascii .
1.20 schwarze 352: .Pp
353: Special characters are rendered in decimal-encoded UTF-8.

1.21 schwarze 361: .Ss XHTML Output
362: Output produced by

1.21 schwarze 364: conforms to XHTML-1.0 strict.
365: .Pp
366: See

368: for details; beyond generating XHTML tags instead of HTML tags, these
369: output modes are identical.
