NAME
mdoc -- quick reference guide for the -mdoc macro package
SYNOPSIS
groff -mdoc files ...
DESCRIPTION
The -mdoc package is a set of content-based and domain-based macros used to format the BSD man pages. The macro names and their meanings are
listed below for quick reference; for a detailed explanation on using the package, see groff_mdoc(7).
The macros are described in two groups, the first includes the structural and physical page layout macros. The second contains the manual
and general text domain macros which differentiate the -oc package from other troff formatting packages.
PAGE STRUCTURE DOMAIN
Title Macros
To create a valid manual page, these three macros, in this order, are required:
.Dd Month day, year Document date.
.Dt DOCUMENT_TITLE [section] [volume] Title, in upper case.
.Os OPERATING_SYSTEM [version/release] Operating system (BSD).
Page Layout Macros
Section headers, paragraph breaks, lists and displays.
.Sh Section Headers. Valid headers, in the order of presentation:
NAME Name section, should include the '.Nm' or '.Fn' and the '.Nd' macros.
SYNOPSIS Usage.
DESCRIPTION General description, should include options and parameters.
RETURN VALUES Sections two and three function calls.
ENVIRONMENT Describe environment variables.
FILES Files associated with the subject.
EXAMPLES Examples and suggestions.
DIAGNOSTICS Normally used for section four device interface diagnostics.
ERRORS Sections two and three error and signal handling.
SEE ALSO Cross references and citations.
STANDARDS Conformance to standards if applicable.
HISTORY If a standard is not applicable, the history of the subject should be given.
BUGS Gotchas and caveats.
other Customized headers may be added at the authors discretion.
.Ss Subsection Headers.
.Pp Paragraph Break. Vertical space (one line).
.D1 (D-one) Display-one Indent and display one text line.
.Dl (D-ell) Display-one literal. Indent and display one line of literal text.
.Bd Begin-display block. Display options:
-ragged Unjustified (ragged edges).

right Left aligns block 2 inches from right.
xxn Where xx is a number from 4n to 99n.
Aa Where Aa is a callable macro name.
string The width of string is used.
.Ed End-display (matches .Bd).
.Bl Begin-list. Create lists or columns. Options:
List-types
-bullet Bullet Item List
-item Unlabeled List
-enum Enumerated List
-tag Tag Labeled List
-diag Diagnostic List
-hang Hanging Labeled List
-ohang Overhanging Labeled List
-inset Inset or Run-on Labeled List
List-parameters
-offset (All lists.) See '.Bd' begin-display above.
-width (-tag and -hang lists only.) See '.Bd -offset'.
-compact (All lists.) Suppresses blank lines.
.El End-list.
.It List item.
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:
.Op Fl s Ar file
Produces [-s file]
In this example, the option enclosure macro '.Op' is parsed, and calls the callable content macro 'Fl' which operates on the argument 's' and
then calls the callable content macro 'Ar' which operates on the argument 'file'. Some macros may be callable, but are not parsed and vice
versa. These macros are indicated in the parsed and callable columns below.
Unless stated, manual domain macros share a common syntax:
.Va argument [ . , ; : ( ) [ ] argument ... ]
Note: Opening and closing punctuation characters are only recognized as such if they are presented one at a time. The string '),' is not
recognized as punctuation and will be output with a leading white space and in what ever font the calling macro uses. The argument list '] )
,' 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 '&'. For example the following
string,
.Ar file1 , file2 , file3 ) . Produces file1, file2, file3).

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