whether in a request, macro, or text line, is ignored to the end of the line. |
|
A request line beginning with a control character and comment escape |

|
Furthermore, request lines with only a control character and optional |
|
trailing whitespace are stripped from input. |

|
.Ss Special Characters |
|
Special characters are used to encode special glyphs and are rendered |
|
differently across output media. |
|
They may occur in request, macro, and text lines. |
|
Sequences begin with the escape character |
|
.Sq \e |
|
followed by either an open-parenthesis |
|
.Sq \&( |
|
for two-character sequences; an open-bracket |
|
.Sq \&[ |
|
for n-character sequences (terminated at a close-bracket |
|
.Sq \&] ) ; |
|
or a single one character sequence. |
|
.Pp |
|
Examples: |
|
.Bl -tag -width Ds -offset indent -compact |
|
.It Li \e(em |
|
Two-letter em dash escape. |
|
.It Li \ee |
|
One-letter backslash escape. |
|
.El |
|
.Pp |

manual. |
for a complete list. |
|
.Ss Text Decoration |
|
Terms may be text-decorated using the |
|
.Sq \ef |
|
escape followed by an indicator: B (bold), I (italic), R (regular), or P |
|
(revert to previous mode). |
|
A numerical representation 3, 2, or 1 (bold, italic, and regular, |
|
respectively) may be used instead. |
.Pp |
.Pp |
All manuals must have |
Examples: |
.Ux |
.Bl -tag -width Ds -offset indent -compact |
line terminators. |
.It Li \efBbold\efR |
|
Write in bold, then switch to regular font mode. |
|
.It Li \efIitalic\efP |
|
Write in italic, then return to previous font mode. |
|
.El |
|
.Pp |
|
Text decoration is |
|
.Em not |
|
recommended for |
|
.Xr mdoc 7 , |
|
which encourages semantic annotation. |
|
.Ss Predefined Strings |
|
Predefined strings, like |
|
.Sx Special Characters , |
|
mark special output glyphs. |
|
Predefined strings are escaped with the slash-asterisk, |
|
.Sq \e* : |
|
single-character |
|
.Sq \e*X , |
|
two-character |
|
.Sq \e*(XX , |
|
and N-character |
|
.Sq \e*[N] . |
|
.Pp |
|
Examples: |
|
.Bl -tag -width Ds -offset indent -compact |
|
.It Li \e*(Am |
|
Two-letter ampersand predefined string. |
|
.It Li \e*q |
|
One-letter double-quote predefined string. |
|
.El |
|
.Pp |
|
Predefined strings are not recommended for use, |
|
as they differ across implementations. |
|
Those supported by |
|
.Xr mandoc 1 |
|
are listed in |
|
.Xr mandoc_char 7 . |
|
Manuals using these predefined strings are almost certainly not portable. |
|
.Ss Whitespace |
|
Whitespace consists of the space character. |
|
In text lines, whitespace is preserved within a line. |
|
In request and macro lines, whitespace delimits arguments and is discarded. |
|
.Pp |
|
Unescaped trailing spaces are stripped from text line input unless in a |
|
literal context. |
|
In general, trailing whitespace on any input line is discouraged for |
|
reasons of portability. |
|
In the rare case that a blank character is needed at the end of an |
|
input line, it may be forced by |
|
.Sq \e\ \e& . |
|
.Pp |
|
Literal space characters can be produced in the output |
|
using escape sequences. |
|
In macro lines, they can also be included in arguments using quotation; see |
|
.Sx MACRO SYNTAX |
|
for details. |
|
.Pp |
|
Blank text lines, which may include whitespace, are only permitted |
|
within literal contexts. |
|
If the first character of a text line is a space, that line is printed |
|
with a leading newline. |
|
.Ss Scaling Widths |
|
Many requests and macros support scaled widths for their arguments. |
|
The syntax for a scaled width is |
|
.Sq Li [+-]?[0-9]*.[0-9]*[:unit:] , |
|
where a decimal must be preceded or followed by at least one digit. |
|
Negative numbers, while accepted, are truncated to zero. |
|
.Pp |
|
The following scaling units are accepted: |
|
.Pp |
|
.Bl -tag -width Ds -offset indent -compact |
|
.It c |
|
centimetre |
|
.It i |
|
inch |
|
.It P |
|
pica (~1/6 inch) |
|
.It p |
|
point (~1/72 inch) |
|
.It f |
|
synonym for |
|
.Sq u |
|
.It v |
|
default vertical span |
|
.It m |
|
width of rendered |
|
.Sq m |
|
.Pq em |
|

|
.It n |
|
width of rendered |
|
.Sq n |
|
.Pq en |
|
character |
|
.It u |
|
default horizontal span |
|
.It M |
|
mini-em (~1/100 em) |
|
.El |
|
.Pp |
|
Using anything other than |
|
.Sq m , |
|
.Sq n , |
|
.Sq u , |
|
or |
|
.Sq v |
|
is necessarily non-portable across output media. |
|
See |
|
.Sx COMPATIBILITY . |
|
.Pp |
|
If a scaling unit is not provided, the numerical value is interpreted |
|
under the default rules of |
|
.Sq v |
|
for vertical spaces and |
|
.Sq u |
|
for horizontal ones. |
|
.Pp |
|
Examples: |
|
.Bl -tag -width ".Bl -tag -width 2i" -offset indent -compact |
|
.It Li \&.Bl -tag -width 2i |

|
.Xr man 7 |
|
.It Li \&.sp 2v |
|

|
.El |
|
.Ss Sentence Spacing |
|
Each sentence should terminate at the end of an input line. |
|
By doing this, a formatter will be able to apply the proper amount of |
|
spacing after the end of sentence (unescaped) period, exclamation mark, |
|
or question mark followed by zero or more non-sentence closing |
|
delimiters |
|
.Po |
|
.Sq \&) , |
|
.Sq \&] , |
|
.Sq \&' , |
|
.Sq \&" |
|
.Pc . |
|
.Pp |
|
The proper spacing is also intelligently preserved if a sentence ends at |
|
the boundary of a macro line. |
|
.Pp |
|
Examples: |
|
.Bd -literal -offset indent -compact |
|
Do not end sentences mid-line like this. Instead, |
|
end a sentence like this. |
|
A macro would end like this: |

.Sh MACRO SYNTAX |
|
Macros are provided by the |
|
.Xr mdoc 7 |
|
and |
|
.Xr man 7 |
|
languages and can be defined by the |
|
.Sx \&de |
|
request. |
|
When called, they follow the same syntax as requests, except that |
|
macro arguments may optionally be quoted by enclosing them |
|
in double quote characters |
|
.Pq Sq \(dq . |
|
Quoted text, even if it contains whitespace or would cause |
|
a macro invocation when unquoted, is always considered literal text. |
|
Inside quoted text, pairs of double quote characters |
|
.Pq Sq Qq |
|
resolve to single double quote characters. |
|
.Pp |
|
To be recognised as the beginning of a quoted argument, the opening |
|
quote character must be preceded by a space character. |
|
A quoted argument extends to the next double quote character that is not |
|
part of a pair, or to the end of the input line, whichever comes earlier. |
|
Leaving out the terminating double quote character at the end of the line |
|
is discouraged. |
|
For clarity, if more arguments follow on the same input line, |
|
it is recommended to follow the terminating double quote character |
|
by a space character; in case the next character after the terminating |
|
double quote character is anything else, it is regarded as the beginning |
|
of the next, unquoted argument. |
|
.Pp |
|
Both in quoted and unquoted arguments, pairs of backslashes |
|
.Pq Sq \e\e |
|
resolve to single backslashes. |
|
In unquoted arguments, space characters can alternatively be included |
|
by preceding them with a backslash |
|
.Pq Sq \e\~ , |
|
but quoting is usually better for clarity. |
|
