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

70: comments, escape sequences, whitespace, and quoting.
1.140 ! schwarze 71: .Pp
1.16 kristaps 72: Each

1.111 schwarze 476: .Sh MACRO SYNTAX
477: The
478: .Nm
479: macros are classified by scope: line scope or block scope.
480: Line macros are only scoped to the current line (and, in some
481: situations, the subsequent line).
482: Block macros are scoped to the current line and subsequent lines until
483: closed by another block macro.
484: .Ss Line Macros
485: Line macros are generally scoped to the current line, with the body
486: consisting of zero or more arguments.
487: If a macro is scoped to the next line and the line arguments are empty,
488: the next line, which must be text, is used instead.
489: Thus:
490: .Bd -literal -offset indent
491: \&.I
492: foo
493: .Ed
494: .Pp
495: is equivalent to
496: .Sq \&.I foo .
497: If next-line macros are invoked consecutively, only the last is used.
498: If a next-line macro is followed by a non-next-line macro, an error is
1.134 schwarze 499: raised.

530: .Ss Block Macros
531: Block macros comprise a head and body.
532: As with in-line macros, the head is scoped to the current line and, in
533: one circumstance, the next line (the next-line stipulations as in
534: .Sx Line Macros
535: apply here as well).

542: .Ed

544: The closure of body scope may be to the section, where a macro is closed
545: by
546: .Sx \&SH ;

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

585: If a block macro is next-line scoped, it may only be followed by in-line
586: macros for decorating text.

595: font escape sequences can be used to choose fonts.
596: In text lines, the effect of manual font selection by escape sequences
597: only lasts until the next macro invocation; in macro lines, it only lasts
598: until the end of the macro scope.
599: Note that macros like
600: .Sx \&BR
601: open and close a font scope for each argument.
