1.8 kristaps 107: .Ss Input Formats
108: The

110: utility accepts
111: .Xr mdoc 7
112: and
113: .Xr man 7
114: input with
1.10 kristaps 115: .Fl m Ns Ar doc
1.8 kristaps 116: and
1.10 kristaps 117: .Fl m Ns Ar an ,
1.8 kristaps 118: respectively. The
119: .Xr mdoc 7
120: format is
121: .Em strongly
1.26 kristaps 122: recommended;
1.8 kristaps 123: .Xr man 7
124: should only be used for legacy manuals.
1.32 kristaps 125: .
1.11 kristaps 126: .Pp
1.12 kristaps 127: A third option,
128: .Fl m Ns Ar andoc ,
1.13 kristaps 129: which is also the default, determines encoding on-the-fly: if the first
1.26 kristaps 130: non-comment macro is
1.27 kristaps 131: .Sq \&Dd
1.13 kristaps 132: or
1.27 kristaps 133: .Sq \&Dt ,
1.26 kristaps 134: the
1.13 kristaps 135: .Xr mdoc 7
136: parser is used; otherwise, the
137: .Xr man 7
138: parser is used.
1.32 kristaps 139: .
1.13 kristaps 140: .Pp
141: If multiple
1.26 kristaps 142: files are specified with
143: .Fl m Ns Ar andoc ,
1.13 kristaps 144: each has its file-type determined this way. If multiple files are
145: specified and
1.12 kristaps 146: .Fl m Ns Ar doc
147: or
148: .Fl m Ns Ar an
149: is specified, then this format is used exclusively.

1.1 kristaps 152: .Ss Output Formats
153: The

1.32 kristaps 190: .
1.19 kristaps 191: .Bl -tag -width Ds
1.1 kristaps 192: .It Fl f Ns Ar ign-scope

1.32 kristaps 196: .
1.45 kristaps 197: .It Fl f Ns Ar ign-escape

1.37 kristaps 225: .Ss Output Options
226: For the time being, only
227: .Fl T Ns Ar html
1.48 kristaps 228: accepts output options:
1.37 kristaps 229: .Bl -tag -width Ds
1.44 kristaps 230: .It Fl O Ns Ar style=style.css
1.37 kristaps 231: The file
232: .Ar style.css
233: is used for an external style-sheet. This must be a valid absolute or
234: relative URI.
1.44 kristaps 235: .It Fl O Ns Ar includes=fmt
1.40 kristaps 236: The string
237: .Ar fmt ,
1.49 kristaps 238: for example,
1.40 kristaps 239: .Ar ../src/%I.html ,
240: is used as a template for linked header files (usually via the
241: .Sq \&In
242: macro). Instances of
1.43 kristaps 243: .Sq \&%I
1.40 kristaps 244: are replaced with the include filename. The default is not to present a
245: hyperlink.
1.44 kristaps 246: .It Fl O Ns Ar man=fmt
1.39 kristaps 247: The string
248: .Ar fmt ,
1.49 kristaps 249: for example,
1.39 kristaps 250: .Ar ../html%S/%N.%S.html ,
251: is used as a template for linked manuals (usually via the
1.37 kristaps 252: .Sq \&Xr
1.40 kristaps 253: macro). Instances of
1.43 kristaps 254: .Sq \&%N
1.40 kristaps 255: and
256: .Sq %S
257: are replaced with the linked manual's name and section, respectively.
258: If no section is included, section 1 is assumed. The default is not to
259: present a hyperlink.

263: .Sh OUTPUT
264: This section documents output details of
265: .Nm .
266: In general, output conforms to the traditional manual style of a header,
1.49 kristaps 267: a body composed of sections and sub-sections, and a footer.
1.48 kristaps 268: .Pp
269: The text style of output characters (non-macro characters, punctuation,
270: and white-space) is dictated by context.
271: .Pp
272: White-space is generally stripped from input. This can be changed with
273: character escapes (specified in
274: .Xr mandoc_char 7 )
275: or literal modes (specified in
276: .Xr mdoc 7
277: and
278: .Xr man 7 ) .
279: .Pp
280: If non-macro punctuation is set apart from words, such as in the phrase
281: .Dq to be \&, or not to be ,
282: it's processed by
283: .Nm ,
284: regardless of output format, according to the following rules: opening
285: punctuation
286: .Po
287: .Sq \&( ,
288: .Sq \&[ ,
289: and
290: .Sq \&{
291: .Pc
292: is not followed by a space; closing punctuation
293: .Po
294: .Sq \&. ,
295: .Sq \&, ,
296: .Sq \&; ,
297: .Sq \&: ,
298: .Sq \&? ,
299: .Sq \&! ,
300: .Sq \&) ,
301: .Sq \&]
302: and
303: .Sq \&}
304: .Pc
305: is not preceded by white-space.
306: .
307: .Pp
308: If the input is
309: .Xr mdoc 7 ,
310: however, these rules are also applied to macro arguments when appropriate.
311: .
312: .
313: .Ss ASCII Output
1.49 kristaps 314: Output produced by
1.48 kristaps 315: .Fl T Ns Ar ascii ,
316: which is the default, is rendered in standard 7-bit ASCII documented in
317: .Xr ascii 7 .
318: .Pp
319: Font styles are applied by using back-spaced encoding such that an
320: underlined character
321: .Sq c
322: is rendered as
323: .Sq _ Ns \e[bs] Ns c ,
324: where
325: .Sq \e[bs]
326: is the back-space character number 8. Emboldened characters are rendered as
327: .Sq c Ns \e[bs] Ns c .
328: .Pp
329: The special characters documented in
330: .Xr mandoc_char 7
331: are rendered best-effort in an ASCII equivalent.
332: .Pp
333: Output width is limited to 78 visible columns unless literal input lines
334: exceed this limit.
335: .
336: .
337: .Ss HTML Output
338: Output produced by
339: .Fl T Ns Ar html
1.50 kristaps 340: conforms to HTML-4.01 strict.
1.48 kristaps 341: .Pp
342: Font styles and page structure are applied using CSS2. By default, no
343: font style is applied to any text, although CSS2 is hard-coded to format
344: the basic structure of output.
345: .Pp
346: The
347: .Pa example.style.css
348: file documents the range of styles applied to output and, if used, will
349: cause rendered documents to appear as they do in
350: .Fl T Ns Ar ascii .
351: .Pp
352: Special characters are rendered in decimal-encoded UTF-8.
353: .
354: .
1.50 kristaps 355: .Ss XHTML Output
356: Output produced by
357: .Fl T Ns Ar xhtml
358: conforms to XHTML-1.0 strict.
359: .Pp
360: See
361: .Sx HTML Output
362: for details; beyond generating XHTML tags instead of HTML tags, these
363: output modes are identical.
