.Dt MAN 7
.Os
.Sh NAME
.Nm man
.Nd legacy formatting language for manual pages
.Sh DESCRIPTION
The
.Nm man
language was the standard formatting language for
.At
manual pages from 1979 to 1989.
Do not use it to write new manual pages: it is a purely presentational
language and lacks support for semantic markup.
Use the
.Xr mdoc 7
language, instead.
.Pp
In a
.Nm
document, lines beginning with the control character
.Sq \&.
are called
.Dq macro lines .
The first word is the macro name.
It usually consists of two capital letters.
For a list of portable macros, see
.Sx MACRO OVERVIEW .
The words following the macro name are arguments to the macro.
.Pp
Lines not beginning with the control character are called
.Dq text lines .
They provide free-form text to be printed; the formatting of the text
depends on the respective processing context:
.Bd -literal -offset indent
\&.SH Macro lines change control state.
Text lines are interpreted within the current state.
.Ed
.Pp
Many aspects of the basic syntax of the
.Nm
language are based on the
.Xr roff 7
language; see the
.Em LANGUAGE SYNTAX
and
.Em MACRO SYNTAX
sections in the
.Xr roff 7
manual for details, in particular regarding
comments, escape sequences, whitespace, and quoting.
.Pp
Each
.Nm
document starts with the
.Ic TH
macro specifying the document's name and section, followed by the
.Sx NAME
section formatted as follows:
.Bd -literal -offset indent
\&.TH PROGNAME 1 1979-01-10
\&.SH NAME
\efBprogname\efR \e(en one line about what it does
.Ed
.Sh MACRO OVERVIEW

.Sh MACRO REFERENCE
This section is a canonical reference to all macros, arranged
alphabetically.
For the scoping of individual macros, see
.Sx MACRO SYNTAX .
.Bl -tag -width 3n
.It Ic AT
Sets the volume for the footer for compatibility with man pages from
.At
releases.
The optional arguments specify which release it is from.
.It Ic B
Text is rendered in bold face.
.It Ic BI
Text is rendered alternately in bold face and italic.
Thus,
.Sq .BI this word and that
causes
.Sq this
and
.Sq and
to render in bold face, while
.Sq word
and
.Sq that
render in italics.
Whitespace between arguments is omitted in output.
.Pp
Example:
.Pp
.Dl \&.BI bold italic bold italic
.It Ic BR
Text is rendered alternately in bold face and roman (the default font).
Whitespace between arguments is omitted in output.
See also
.Ic BI .

This has no effect unless the tabulator positions were changed with the
.Xr roff 7
.Ic ta
request.
.It Ic EE
This is a non-standard Version 9
.At
extension later adopted by GNU.
In
.Xr mandoc 1 ,
it does the same as the
.Xr roff 7
.Ic fi
request (switch to fill mode).
.It Ic EX
This is a non-standard Version 9
.At
extension later adopted by GNU.
In
.Xr mandoc 1 ,
it does the same as the
.Xr roff 7
.Ic nf
request (switch to no-fill mode).
.It Ic HP
Begin a paragraph whose initial output line is left-justified, but
subsequent output lines are indented, with the following syntax:
.Pp
.D1 Pf . Ic HP Op Ar width
.Pp
The
.Ar width
argument is a
.Xr roff 7
scaling width.
If specified, it's saved for later paragraph left margins;
if unspecified, the saved or default width is used.
.Pp
This macro is portable, but deprecated
because it has no good representation in HTML output,
usually ending up indistinguishable from
.Ic PP .
.It Ic I
Text is rendered in italics.
.It Ic IB
Text is rendered alternately in italics and bold face.
Whitespace between arguments is omitted in output.
See also
.Ic BI .
.It Ic IP
Begin an indented paragraph with the following syntax:
.Pp
.D1 Pf . Ic IP Op Ar head Op Ar width
.Pp
The
.Ar width
argument is a
.Xr roff 7
scaling width defining the left margin.
It's saved for later paragraph left-margins; if unspecified, the saved or
default width is used.
.Pp
The
.Ar head
argument is used as a leading term, flushed to the left margin.
This is useful for bulleted paragraphs and so on.
.It Ic IR
Text is rendered alternately in italics and roman (the default font).
Whitespace between arguments is omitted in output.

A synonym for
.Ic PP .
.It Ic PD
Specify the vertical space to be inserted before each new paragraph.
.br
The syntax is as follows:
.Pp
.D1 Pf . Ic PD Op Ar height
.Pp
The
.Ar height
argument is a
.Xr roff 7
scaling width.
It defaults to
.Cm 1v .
If the unit is omitted,
.Cm v
is assumed.
.Pp
This macro affects the spacing before any subsequent instances of
.Ic HP ,
.Ic IP ,
.Ic LP ,
.Ic P ,
.Ic PP ,
.Ic SH ,
.Ic SS ,
.Ic SY ,
and
.Ic TP .

Text is rendered alternately in roman (the default font) and bold face.
Whitespace between arguments is omitted in output.
See also
.Ic BI .
.It Ic RE
Explicitly close out the scope of a prior

.Ic RS
invocation.
.Pp
The syntax is as follows:
.Pp
.D1 Pf . Ic RE Op Ar level
.Pp
Without an argument, the most recent
.Ic RS
block is closed out.

.Ic IP .
.It Ic TH
Set the name of the manual page for use in the page header
and footer with the following syntax:
.Pp
.D1 Pf . Ic TH Ar name section date Op Ar source Op Ar volume
.Pp
Conventionally, the document
.Ar name
is given in all caps.
The
.Ar section
is usually a single digit, in a few cases followed by a letter.
The recommended
.Ar date
format is
.Sy YYYY-MM-DD
as specified in the ISO-8601 standard;
if the argument does not conform, it is printed verbatim.
If the
.Ar date
is empty or not specified, the current date is used.
The optional
.Ar source
string specifies the organisation providing the utility.
When unspecified,
.Xr mandoc 1
uses its
.Fl Ios
argument.
The
.Ar volume
string replaces the default volume title of the
.Ar section .
.Pp
Examples:
.Pp
.Dl \&.TH CVS 5 "1992-02-12" GNU
.It Ic TP
Begin a paragraph where the head, if exceeding the indentation width, is

advancing to the indentation width.
Subsequent output lines are indented.
The syntax is as follows:
.Bd -unfilled -offset indent
.Pf . Ic TP Op Ar width
.Ar head No \e" one line
.Ar body
.Ed
.Pp
The
.Ar width
argument is a
.Xr roff 7
scaling width.
If specified, it's saved for later paragraph left-margins; if
unspecified, the saved or default width is used.

Like
.Ic TP ,
except that no vertical spacing is inserted before the paragraph.
This is a non-standard GNU extension
and very rarely used even in GNU manual pages.
.It Ic UC
Sets the volume for the footer for compatibility with man pages from
.Bx
releases.
The optional first argument specifies which release it is from.
.It Ic UE
End a uniform resource identifier block started with

.Pp
.D1 Pf . Ic in Op Ar width
.Pp
If
.Ar width
is signed, the new offset is relative.
Otherwise, it is absolute.
This value is reset upon the next paragraph, section, or sub-section.
.El
.Sh MACRO SYNTAX
The
.Nm
macros are classified by scope: line scope or block scope.
Line macros are only scoped to the current line (and, in some
situations, the subsequent line).
Block macros are scoped to the current line and subsequent lines until
closed by another block macro.
.Ss Line Macros
Line macros are generally scoped to the current line, with the body
consisting of zero or more arguments.
If a macro is scoped to the next line and the line arguments are empty,
the next line, which must be text, is used instead.
Thus:
.Bd -literal -offset indent
\&.I
foo
.Ed
.Pp
is equivalent to
.Sq .I foo .
If next-line macros are invoked consecutively, only the last is used.
If a next-line macro is followed by a non-next-line macro, an error is
raised.
.Pp
The syntax is as follows:
.Bd -literal -offset indent
\&.YO \(lBbody...\(rB
\(lBbody...\(rB
.Ed
.Bl -column "MacroX" "ArgumentsX" "ScopeXXXXX" "CompatX" -offset indent

.El
.Ss Block Macros
Block macros comprise a head and body.
As with in-line macros, the head is scoped to the current line and, in
one circumstance, the next line (the next-line stipulations as in
.Sx Line Macros
apply here as well).
.Pp
The syntax is as follows:
.Bd -literal -offset indent
\&.YO \(lBhead...\(rB
\(lBhead...\(rB
\(lBbody...\(rB
.Ed
.Pp
The closure of body scope may be to the section, where a macro is closed
by
.Ic SH ;
sub-section, closed by a section or
.Ic SS ;
or paragraph, closed by a section, sub-section,
.Ic HP ,
.Ic IP ,
.Ic LP ,
.Ic P ,
.Ic PP ,
.Ic RE ,

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

.El
.Pp
If a block macro is next-line scoped, it may only be followed by in-line
macros for decorating text.
.Ss Font handling
In
.Nm
documents, both
.Sx Physical markup
macros and
.Xr roff 7
.Ql \ef
font escape sequences can be used to choose fonts.
In text lines, the effect of manual font selection by escape sequences
only lasts until the next macro invocation; in macro lines, it only lasts
until the end of the macro scope.
Note that macros like
.Ic BR
open and close a font scope for each argument.

.Sh HISTORY
The
.Nm
language first appeared as a macro package for the roff typesetting
system in
.At v7 .
It was later rewritten by James Clark as a macro package for groff.
Eric S. Raymond wrote the extended
.Nm
macros for groff in 2007.
The stand-alone implementation that is part of the
.Xr mandoc 1
utility written by Kristaps Dzonsons appeared in
.Ox 4.6 .
