.Sh MACRO SYNTAX |
|
Macros are one to three three characters in length and begin with a |
|
control character , |
|
.Sq \&. , |
|
at the beginning of the line. An arbitrary amount of whitespace may |
|
sit between the control character and the macro name. Thus, |
|
.Sq .PP |
|
and |
|
.Sq \&.\ \ \ PP |
|
are equivalent. |
|
. |
.Pp |
.Pp |
The following is a table of all available escapes. |
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 is used instead, |
|
else the general syntax is used. Thus: |

.It \\(em |
If next-line macros are invoked consecutively, only the last is used. |
.Pq em-dash |
If a next-line macro is proceded by a block macro, it is ignored. |

.Sh STRUCTURE |

Macros are case in-sensitive and one to three three characters in |
|
length. All follow the same structural rules: |

|
.Ed |

This follows the behaviour of the |
|
.Sq TP |
|
except for the macro syntax (all arguments on the line, instead of |
|
having next-line scope). If |
|
.Va width |
|
is specified, it's saved for later paragraph left-margins; if |
|
unspecified, the saved or default width is used. |
|
.It IR |
|
Text is rendered alternately in italics and roman (the default font). |
|
Whitespace between arguments is omitted in output. |
|
.It LP, P, PP |
|
Begin an undecorated paragraph. The scope of a paragraph is closed by a |
|
subsequent paragraph, sub-section, section, or end of file. The saved |
|
paragraph left-margin width is re-set to the default. |
|
.It R |
|
Text is rendered in roman (the default font). |
|
.It RB |

Text is rendered alternately in roman (the default font) and bold face. |

Begin a part setting the left margin. The left margin controls the |
|
offset, following an initial indentation, to un-indented text such as |

that of |

Text is rendered in small size (one point smaller than the default font) |
|
bold face. |
|
.It SH |
|
Begin a section. The scope of a section is only closed by another |
|
section or the end of file. The paragraph left-margin width is re-set |
|
to the default. |
|
.It SM |
|
Text is rendered in small size (one point smaller than the default |
|
font). |

Begin a sub-section. The scope of a sub-section is closed by a |

subsequent sub-section, section, or end of file. The paragraph |
|
left-margin width is re-set to the default. |

This section documents compatibility with other roff implementations, at |

this time limited to |

.Xr groff 1 . |
|
.Bl -hyphen |
|

|
In quoted literals, groff allowed pair-wise double-quotes to produce a |

standalone double-quote in formatted output. This idiosyncratic |
|
behaviour is no longer applicable. |

The |

|
Blocks of whitespace are stripped from both macro and free-form text |
|
lines (except when in literal mode), while groff would retain whitespace |
|
in free-form text lines. |
