1.32 kristaps 24: .Nm man
1.111 schwarze 25: .Nd legacy formatting language for manual pages
1.1 kristaps 26: .Sh DESCRIPTION
1.140 schwarze 27: The
1.32 kristaps 28: .Nm man
1.140 schwarze 29: language was the standard formatting language for
30: .At
31: manual pages from 1979 to 1989.
32: Do not use it to write new manual pages: it is a purely presentational
33: language and lacks support for semantic markup.
1.19 kristaps 34: Use the
1.32 kristaps 35: .Xr mdoc 7
1.1 kristaps 36: language, instead.
1.32 kristaps 37: .Pp
1.111 schwarze 38: In a
1.32 kristaps 39: .Nm
1.111 schwarze 40: document, lines beginning with the control character
1.32 kristaps 41: .Sq \&.
1.111 schwarze 42: are called
43: .Dq macro lines .
44: The first word is the macro name.
45: It usually consists of two capital letters.
1.140 schwarze 46: For a list of portable macros, see
1.111 schwarze 47: .Sx MACRO OVERVIEW .
48: The words following the macro name are arguments to the macro.
49: .Pp
50: Lines not beginning with the control character are called
51: .Dq text lines .
52: They provide free-form text to be printed; the formatting of the text
53: depends on the respective processing context:
1.32 kristaps 54: .Bd -literal -offset indent
1.1 kristaps 55: \&.SH Macro lines change control state.
1.106 kristaps 56: Text lines are interpreted within the current state.
1.32 kristaps 57: .Ed
1.103 kristaps 58: .Pp
1.111 schwarze 59: Many aspects of the basic syntax of the
1.103 kristaps 60: .Nm
1.111 schwarze 61: language are based on the
62: .Xr roff 7
63: language; see the
64: .Em LANGUAGE SYNTAX
1.106 kristaps 65: and
1.111 schwarze 66: .Em MACRO SYNTAX
67: sections in the
68: .Xr roff 7
69: manual for details, in particular regarding
70: comments, escape sequences, whitespace, and quoting.
1.140 schwarze 71: .Pp
1.16 kristaps 72: Each
1.32 kristaps 73: .Nm
1.140 schwarze 74: document starts with the
1.39 kristaps 75: .Sx \&TH
1.140 schwarze 76: macro specifying the document's name and section, followed by the
77: .Sx NAME
78: section formatted as follows:

477: .Nm
478: macros are classified by scope: line scope or block scope.
479: Line macros are only scoped to the current line (and, in some
480: situations, the subsequent line).
481: Block macros are scoped to the current line and subsequent lines until
482: closed by another block macro.
483: .Ss Line Macros
484: Line macros are generally scoped to the current line, with the body
485: consisting of zero or more arguments.
486: If a macro is scoped to the next line and the line arguments are empty,
487: the next line, which must be text, is used instead.
488: Thus:
489: .Bd -literal -offset indent
490: \&.I
491: foo
492: .Ed
493: .Pp
494: is equivalent to
495: .Sq \&.I foo .
496: If next-line macros are invoked consecutively, only the last is used.
497: If a next-line macro is followed by a non-next-line macro, an error is
1.134 schwarze 498: raised.

528: Block macros comprise a head and body.
529: As with in-line macros, the head is scoped to the current line and, in
530: one circumstance, the next line (the next-line stipulations as in

556: No closure refers to an explicit block closing macro.
557: .Pp
558: As a rule, block macros may not be nested; thus, calling a block macro
559: while another block macro scope is open, and the open scope is not
560: implicitly closed, is syntactically incorrect.
