1.1 kristaps 27: .Sh DESCRIPTION
28: The
1.32 kristaps 29: .Nm man
1.20 kristaps 30: language was historically used to format
1.32 kristaps 31: .Ux
1.19 kristaps 32: manuals. This reference document describes its syntax, structure, and
33: usage.
1.32 kristaps 34: .
35: .Pp
36: .Bf -emphasis
1.20 kristaps 37: Do not use
1.32 kristaps 38: .Nm
1.20 kristaps 39: to write your manuals.
1.32 kristaps 40: .Ef
1.19 kristaps 41: Use the
1.32 kristaps 42: .Xr mdoc 7
1.1 kristaps 43: language, instead.
1.32 kristaps 44: .
45: .Pp
1.1 kristaps 46: An
1.32 kristaps 47: .Nm
1.1 kristaps 48: document follows simple rules: lines beginning with the control
1.20 kristaps 49: character
1.32 kristaps 50: .Sq \&.
1.1 kristaps 51: are parsed for macros. Other lines are interpreted within the scope of
52: prior macros:
1.32 kristaps 53: .Bd -literal -offset indent
1.1 kristaps 54: \&.SH Macro lines change control state.
55: Other lines are interpreted within the current state.

1.1 kristaps 59: .Sh INPUT ENCODING
1.32 kristaps 60: .Nm
1.14 kristaps 61: documents may contain only graphable 7-bit ASCII characters, the
1.19 kristaps 62: space character, and the tabs character. All manuals must have
1.32 kristaps 63: .Ux
1.20 kristaps 64: line termination.
1.32 kristaps 65: .
66: .Pp
1.5 kristaps 67: Blank lines are acceptable; where found, the output will assert a
1.1 kristaps 68: vertical space.
1.32 kristaps 69: .
70: .Pp
1.4 kristaps 71: The
1.32 kristaps 72: .Sq \ec
1.4 kristaps 73: escape is common in historical
1.32 kristaps 74: .Nm
1.4 kristaps 75: documents; if encountered at the end of a word, it ensures that the
76: subsequent word isn't off-set by whitespace.
1.28 kristaps 77: .
78: .
1.32 kristaps 79: .Ss Comments
1.21 kristaps 80: Text following a
1.32 kristaps 81: .Sq \e\*" ,
1.21 kristaps 82: whether in a macro or free-form text line, is ignored to the end of
83: line. A macro line with only a control character and comment escape,
1.32 kristaps 84: .Sq \&.\e" ,
1.22 kristaps 85: is also ignored. Macro lines with only a control charater and
86: optionally whitespace are stripped from input.
1.28 kristaps 87: .
88: .
1.32 kristaps 89: .Ss Special Characters
1.21 kristaps 90: Special characters may occur in both macro and free-form lines.
91: Sequences begin with the escape character
1.32 kristaps 92: .Sq \e
1.20 kristaps 93: followed by either an open-parenthesis
1.32 kristaps 94: .Sq \&(
1.1 kristaps 95: for two-character sequences; an open-bracket
1.32 kristaps 96: .Sq \&[
1.1 kristaps 97: for n-character sequences (terminated at a close-bracket
1.32 kristaps 98: .Sq \&] ) ;
1.21 kristaps 99: or a single one-character sequence. See
1.32 kristaps 100: .Xr mandoc_char 7
1.21 kristaps 101: for a complete list. Examples include
1.32 kristaps 102: .Sq \e(em
103: .Pq em-dash
1.21 kristaps 104: and
1.32 kristaps 105: .Sq \ee
106: .Pq back-slash .
1.28 kristaps 107: .
108: .
1.32 kristaps 109: .Ss Text Decoration
1.21 kristaps 110: Terms may be text-decorated using the
1.32 kristaps 111: .Sq \ef
1.21 kristaps 112: escape followed by an indicator: B (bold), I, (italic), or P and R
113: (Roman, or reset).
1.28 kristaps 114: .
115: .
1.32 kristaps 116: .Ss Whitespace
1.17 kristaps 117: Unless specifically escaped, consecutive blocks of whitespace are pruned
118: from input. These are later re-added, if applicable, by a front-end
119: utility such as
1.32 kristaps 120: .Xr mandoc 1 .
1.28 kristaps 121: .
1.38 kristaps 122: .Ss Scaling Widths
123: Many macros support scaled widths for their arguments, such as
124: stipulating a two-inch paragraph indentation with the following:
125: .Bd -literal -offset indent
126: \&.HP 2i
127: .Ed
128: .
129: .Pp
130: The syntax for scaled widths is
131: .Sq Li [+-]?[0-9]*.[0-9]*[:unit:]? ,
132: where a decimal must be preceded or proceeded by at least one digit.
133: Negative numbers, while accepted, are truncated to zero. The following
134: scaling units are accepted:
135: .
136: .Pp
137: .Bl -tag -width Ds -offset indent -compact
138: .It c
139: centimetre
140: .It i
141: inch
142: .It P
143: pica (~1/6 inch)
144: .It p
145: point (~1/72 inch)
146: .It f
147: synonym for
148: .Sq u
149: .It v
150: default vertical span
151: .It m
152: width of rendered
153: .Sq m
154: .Pq em
155: character
156: .It n
157: width of rendered
158: .Sq n
159: .Pq en
160: character
161: .It u
162: default horizontal span
163: .It M
164: mini-em (~1/100 em)
165: .El
166: .Pp
167: Using anything other than
168: .Sq m ,
169: .Sq n ,
170: .Sq u ,
171: or
172: .Sq v
173: is necessarily non-portable across output media. See
174: .Sx COMPATIBILITY .
175: .
176: .Pp
177: If a scaling unit is not provided, the numerical value is interpreted
178: under the default rules of
179: .Sq v
180: for vertical spaces and
181: .Sq u
182: for horizontal ones.
183: .Em Note :
184: this differs from
185: .Xr mdoc 7 ,
186: which, if a unit is not provided, will instead interpret the string as
187: literal text.

1.22 kristaps 299: .Sh MACRO SYNTAX
1.2 kristaps 300: Macros are one to three three characters in length and begin with a
1.4 kristaps 301: control character ,
1.32 kristaps 302: .Sq \&. ,
1.2 kristaps 303: at the beginning of the line. An arbitrary amount of whitespace may
1.39 kristaps 304: sit between the control character and the macro name. Thus, the
305: following are equivalent:
306: .Bd -literal -offset indent
307: \&.PP
308: \&.\ \ \ PP
309: .Ed
1.32 kristaps 310: .
311: .Pp
1.1 kristaps 312: The
1.32 kristaps 313: .Nm
1.30 kristaps 314: macros are classified by scope: line scope or block scope. Line
1.22 kristaps 315: macros are only scoped to the current line (and, in some situations,
316: the subsequent line). Block macros are scoped to the current line and
317: subsequent lines until closed by another block macro.
1.28 kristaps 318: .
319: .
1.32 kristaps 320: .Ss Line Macros
1.30 kristaps 321: Line macros are generally scoped to the current line, with the body
322: consisting of zero or more arguments. If a macro is scoped to the next
323: line and the line arguments are empty, the next line is used instead,
324: else the general syntax is used. Thus:
1.32 kristaps 325: .Bd -literal -offset indent

1.20 kristaps 331: is equivalent to
1.32 kristaps 332: .Sq \&.I foo .
1.35 kristaps 333: If next-line macros are invoked consecutively, only the last is used.
334: If a next-line macro is proceded by a block macro, it is ignored.

1.26 kristaps 493: except for the macro syntax (all arguments on the line, instead of
1.27 kristaps 494: having next-line scope). If
1.32 kristaps 495: .Va width
1.27 kristaps 496: is specified, it's saved for later paragraph left-margins; if
497: unspecified, the saved or default width is used.
1.39 kristaps 498: .Ss \&IR
1.22 kristaps 499: Text is rendered alternately in italics and roman (the default font).
500: Whitespace between arguments is omitted in output.
1.39 kristaps 501: .Ss \&LP
1.22 kristaps 502: Begin an undecorated paragraph. The scope of a paragraph is closed by a
1.27 kristaps 503: subsequent paragraph, sub-section, section, or end of file. The saved
504: paragraph left-margin width is re-set to the default.

1.30 kristaps 523: Begin a part setting the left margin. The left margin controls the

1.22 kristaps 540: Begin a section. The scope of a section is only closed by another

1.39 kristaps 572: .Ss \&TP
1.25 kristaps 573: Begin a paragraph where the head, if exceeding the indentation width, is
1.24 kristaps 574: followed by a newline; if not, the body follows on the same line after a

1.36 kristaps 601: Don't align to the right margin.
1.39 kristaps 602: .Ss \&nf

1.39 kristaps 608: .Ss \&sp
1.22 kristaps 609: Insert n spaces, where n is the macro's positive numeric argument. If

1.32 kristaps 618: .Xr groff 1 .
619: .Bl -hyphen
620: .It
1.23 kristaps 621: In quoted literals, groff allowed pair-wise double-quotes to produce a
622: standalone double-quote in formatted output. This idiosyncratic
623: behaviour is no longer applicable.
1.32 kristaps 624: .It
1.23 kristaps 625: The

1.23 kristaps 627: macro does not accept negative numbers.
1.32 kristaps 628: .It
1.23 kristaps 629: Blocks of whitespace are stripped from both macro and free-form text
630: lines (except when in literal mode), while groff would retain whitespace
631: in free-form text lines.
