.Sh NAME
.Nm mdoc
.Nd Quick reference guide for the
.Nm \-mdoc
macro package
.Sh SYNOPSIS
.Nm groff
.Fl m Ns Ar doc
.Ar files ...
.Sh DESCRIPTION
The
.Nm \-mdoc
package is a set of manual page domain content-based macros
used to format the
.Bx
man pages.
The macro names and their meanings are
listed below for quick reference; for
a detailed explanation on using the package,
see the tutorial sampler
.Xr mdoc.samples 7 .
.Pp
The macros are described in three domain groups, the first
domain includes the structural and the physical page layout macros.
The second group contains the manual domain
content macros which differentiate the
.Nm -\mdoc
package from other
.Xr troff
formatting packages.
The manual page domain specific content macros
are a subset of the day to day language
used to describe
.Bx
commands, functions, devices and files.
The third group consists of general text
domain macros which apply to other types of documentation
as well as manual pages.
.Sh PAGE STRUCTURAL DOMAIN
.Ss Title Macros

required in the order they are presented:

.Sh MANUAL AND GENERAL TEXT DOMAIN MACROS
The manual and general text domain macros are special in that
most of them are parsed for callable macros
for example:
.Bd -literal -offset indent
\&.Op Fl s Ar file
.Ed
.Pp
In this example, the option enclosure macro
.Ql \&.Op
is parsed, and calls the callable content macro
.Ql \&Fl
which operates on the argument
.Ql s
and then calls the callable content macro
.Ql \&Ar
which operates on the argument
.Ql file .
The result is:
.Pp
.Dl Op Fl s Ar file
.Pp
Some macros may be callable, but are not parsed and vice versa.
These macros are indicated in the
.Em parsed
and
.Em callable columns below.
.Pp
Unless stated, manual page domain macros share a common syntax:
.Pp
.Dl \&.Va argument [\ .\ ,\ ;\ :\ (\ )\ [\ ]\ argument \...\ ]
.Pp
Macros may be given up to nine arguments.
.Sy Note :
Opening and closing
punctuation characters are only recognized as such if they are presented
one at a time.
The string
.Ql "),"
is not recognized as punctuation and will be output with a leading white
space and in what ever font the calling macro uses.
The
the argument list
.Ql "] ) ,"
is recognized as three sequential closing punctuation characters
and a leading white space is not output between the characters
and the previous argument (if any).
The special meaning of a punctuation character may be escaped
with the string
.Ql \e& .
For example the following string,
.Pp
.Dl \&.Ar file1\ , file2\ , file3\ )\ .
.Pp
Produces
.Pp
.D1 .Ar file1 , file2 , file3 ) .

Macro names ending in
.Ql q
quote remaining items on the argument list.
Macro names ending in
.Ql o
begin a quote which may span more than one line of input and
are close quoted with the matching macro name ending in
.Ql c .
Enclosure macros may be nested.
.Pp
Note: the extended argument list macros
.Pf ( Ql \&.Xo ,
.Ql \&.Xc )
and the function enclosure macros
.Pf ( Ql \&.Fo ,
.Ql \&.Fc )
are irregular.
The extended list macros are used when the number of macro arguments
would exceed the
.Xr troff
limitation of nine arguments.
