.Ss Whitespace |
.Pq up arrow |
Whitespace consists of the space character. |
.It \\(da |
In text lines, whitespace is preserved within a line. |
.Pq down arrow |
In macro lines, whitespace delimits arguments and is discarded. |
.It \\(<> |
.Pp |
.Pq left-right arrow |
Unescaped trailing spaces are stripped from text line input unless in a |

.Pq left double-arrow |
In general, trailing whitespace on any input line is discouraged for |
.It \\(rA |
reasons of portability. |

.Ss Quotation |
|
Macro arguments may be quoted with double-quotes; in this case, |
|
whitespace within the quotes is retained as part of the argument. |
|
.Pp |
|
A quoted argument begins with a double-quote preceded by whitespace. |
|
The next double-quote not pairwise adjacent to another double-quote |
|
terminates the literal, regardless of surrounding whitespace. |
|
.Pp |
|
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. |
|
.Pp |
|
Note that any quoted text, even if it would cause a macro invocation |
|
when unquoted, is considered literal text. |
|
.Pp |
|
In text lines, quotes are regarded as opaque text. |
|
.Ss Scaling Widths |
|
Many 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 proceeded by at least one digit. |
|
Negative numbers, while accepted, are truncated to zero. |

The sections in a |
|
.Nm |
|
document are conventionally ordered as they appear above. |
|
Sections should be composed as follows: |
|
.Bl -ohang -offset indent |
|
.It Em NAME |
|
The name(s) and a short description of the documented material. |
|
The syntax for this is generally as follows: |
|
.Pp |
|
.D1 \efBname\efR \e(en description |
|
.It Em LIBRARY |
|
The name of the library containing the documented material, which is |
|
assumed to be a function in a section 2 or 3 manual. |
|
For functions in the C library, this may be as follows: |
|
.Pp |
|
.D1 Standard C Library (libc, -lc) |
|
.It Em SYNOPSIS |
|
Documents the utility invocation syntax, function call syntax, or device |
|
configuration. |
|
.Pp |
|
For the first, utilities (sections 1, 6, and 8), this is |
|
generally structured as follows: |
|
.Pp |
|
.D1 \efBname\efR [-\efBab\efR] [-\efBc\efR\efIarg\efR] \efBpath\efR... |
|
.Pp |

For the second, function calls (sections 2, 3, 9): |
|
.Pp |
|
.D1 \&.B char *name(char *\efIarg\efR); |
|
.Pp |
|
And for the third, configurations (section 4): |
|
.Pp |

.Pp |

Manuals not in these sections generally don't need a |

.It Em DESCRIPTION |
|
This expands upon the brief, one-line description in |
|
.Em NAME . |
|
It usually contains a break-down of the options (if documenting a |
|
command). |
|
.It Em IMPLEMENTATION NOTES |
|
Implementation-specific notes should be kept here. |
|
This is useful when implementing standard functions that may have side |
|
effects or notable algorithmic implications. |
|
.It Em RETURN VALUES |
|
This section documents the return values of functions in sections 2, 3, and 9. |
|
.It Em ENVIRONMENT |
|
Documents any usages of environment variables, e.g., |
|
.Xr environ 7 . |
|
.It Em FILES |
|
Documents files used. |
|
It's helpful to document both the file name and a short description of how |
|
the file is used (created, modified, etc.). |
|
.It Em EXIT STATUS |
|
This section documents the command exit status for |
|
section 1, 6, and 8 utilities. |
|
Historically, this information was described in |
|
.Em DIAGNOSTICS , |
|
a practise that is now discouraged. |
|
.It Em EXAMPLES |
|
Example usages. |
|
This often contains snippets of well-formed, |
|
well-tested invocations. |
|
Make sure that examples work properly! |
|
.It Em DIAGNOSTICS |
|
Documents error conditions. |
|
This is most useful in section 4 manuals. |
|
Historically, this section was used in place of |
|
.Em EXIT STATUS |
|
for manuals in sections 1, 6, and 8; however, this practise is |
|
discouraged. |
|
.It Em ERRORS |
|
Documents error handling in sections 2, 3, and 9. |
|
.It Em SEE ALSO |
|
References other manuals with related topics. |
|
This section should exist for most manuals. |
|
.Pp |
|
.D1 \&.BR bar \&( 1 \&), |
|
.Pp |
|
Cross-references should conventionally be ordered |
|
first by section, then alphabetically. |
|
.It Em STANDARDS |
|
References any standards implemented or used, such as |
|
.Pp |
|
.D1 IEEE Std 1003.2 (\e(lqPOSIX.2\e(rq) |
|
.Pp |
|
If not adhering to any standards, the |
|
.Em HISTORY |
|
section should be used. |
|
.It Em HISTORY |
|
A brief history of the subject, including where support first appeared. |
|
.It Em AUTHORS |
|
Credits to the person or persons who wrote the code and/or documentation. |
|
Authors should generally be noted by both name and email address. |
|
.It Em CAVEATS |
|
Common misuses and misunderstandings should be explained |
|
in this section. |
|
.It Em BUGS |
|
Known bugs, limitations, and work-arounds should be described |
|
in this section. |
|
.It Em SECURITY CONSIDERATIONS |
|
Documents any security precautions that operators should consider. |
