Squid Web Cache documentation

πŸ”— man(8) documentation guidelines and standards

This is a guide for a standard manual page documentation format and template. The aim is to allow documentation writers to focus on documentation and not on specific format and semantics, and to help integrate new texts with translation string automation.

πŸ”— Entities to be documented

All application binary, scripts, and configuration files installed on end server systems are to be documented with a manual page.

πŸ”— Documentation format

Use simplified ngroff syntax. see http://www.fnal.gov/docs/products/ups/ReferenceManual/html/manpages.html for ngroff format details.

Some additional markup is added for integration with po4a translation automation. see https://po4a.org/man/man3/Locale::Po4a::Man.3pm.php for details on specific markup and limits imposed by those tools.

Each .SH section is preceded by an empty line. In ngroff syntax that is a line containing only a dot (.) as demonstrated below between the .TH line and the first .SH line.

The document overview is as follows. Introductory header markup as shown followed by any applicable sections. Which are detailed in more depth below.

.if !'po4a'hide' .TH binary.name 8

πŸ”— .SH NAME

One initial line of content.

  1. name of file being documented. Marked not for translation.
  2. a hyphen. Marked not for translation.
  3. A one-line description of the file. Suitable for use in a title.

If a version number is relevant state it in a separate paragraph below the name details.

For example:

.
.SH NAME
squid \- HTTP Web Proxy caching server.
.PP
Version 1.0

documents

squid - HTTP Web Proxy caching server.

Version 1.0

πŸ”— .SH SYNOPSIS

The plain command line option syntax.

If an option takes a parameter those parameter descriptors are to be left open for translation. All other parts of the syntax are to be marked not for translation.

For example:

.
.SH SYNOPSIS
.if !'po4a'hide' .B squid
.if !'po4a'hide' .B [\-dh]
.if !'po4a'hide' .B [\-f
config\-file
.if !'po4a'hide' .B ]

documents:

squid [-dh] [-f config-file ]

πŸ”— .SH DESCRIPTION

The full description of what the file object is all about. It should but is not required to begin with the file name in bold. Paragraphs in the description are separated by .PP tags.

Use .if !β€˜po4a’hide’ to mark any lines of syntax as not for translation.

Any words which name a file or binary should be marked out in bold.

For example:

.
.SH DESCRIPTION
.PP
.B squid
is a high-performance proxy caching server for web clients,
supporting FTP, gopher, ICAP, ICP, HTCP and HTTP data objects.
Unlike traditional caching software,
Squid handles all requests in a single, non-blocking process.
.PP
Squid keeps meta data and especially hot objects cached in RAM,
caches DNS lookups, supports non-blocking DNS lookups, and implements
negative caching of failed requests.
.
.if !'po4a'hide' http://www.squid-cache.org/

πŸ”— .SH OPTIONS

A fully documented list of available command line options. With an empty line between each. The table column offset of the description text is 12 characters, set on the first .TP tag.

The option switch and any accepted variable names are marked not for translation (unlike in synopsis).

The option description is open for translation. Any repetition of the variable name is highlighted in bold.

For example:

.
.SH OPTIONS
.if !'po4a'hide' .TP 12
.if !'po4a'hide' .B \-d
Write debug info to stderr.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-f config\-file"
Use configuration file
.B config\-file

πŸ”— .SH CONFIGURATION

Optional section specific to application binaries and maybe helper scripts.

Configuration files have their syntax covered under .SH DESCRIPTION

This section should cover snippets of config. Usually from squid.conf. Actual config snippets are to be marked not for translation.

For a multi-line configuration block use .br (lower case is important) to split the lines legibly.

:warning: Any word which begins with a dash / hyphen must be slash-escaped.

For example, URL re-writers would have something like this:

.
.SH CONFIGURATION
.PP The simplest configuration for URL re-writers is to add the script or binary name to
.B squid.conf
like so:
.if !'po4a'hide' .RS
.if !'po4a'hide' .B url_rewrite_program /usr/bin/squid/example.binary
.if !'po4a'hide' .RE
.PP Command line options sent to a helper script or binary are added to
.B squid.conf
following the helper binary name. Like so:
.if !'po4a'hide' .RS
.if !'po4a'hide' .B url_rewrite_program /usr/bin/squid/example.binary \-d
.if !'po4a'hide' .br
.if !'po4a'hide' .B url_rewrite_access ...
.if !'po4a'hide' .RE

πŸ”— .SH KNOWN ISSUES

Optional section specific to application binaries and maybe helper scripts.

Simple set of .PP paragraphs outlining the problems which are known with using the program or script.

πŸ”— .SH AUTHOR

A list of relevant paragraphs specific to the authorship style of the documented program, script or file. Each paragraph ending with a list of author names and contacts and separated by a .PP tag.

For a simple binary or script where the manual was also authored by the same individual(s):

.
.SH AUTHOR
This program and documentation was written by
.if !'po4a'hide' .I Authors Name <author@email.contact>

For a more complicated case where the application has one or more authors and is based on a prior work:

.
.SH AUTHOR
This program was written by
.if !'po4a'hide' .I Authors Name <author@email.contact>
.if !'po4a'hide' .I Authors Name <author@email.contact>
.if !'po4a'hide' .I Authors Name <author@email.contact>
.PP
Based on prior work in
.B older.source
by
.if !'po4a'hide' .I Authors Name <author@email.contact>

Where the manual documentation was by a different author or authors than the program:

.
.SH AUTHOR
This program was written by
.if !'po4a'hide' .I Authors Name <author@email.contact>
.PP
This manual was written by
.if !'po4a'hide' .I Authors Name <author@email.contact>

πŸ”— TODO

The Manual best practice is to provide a man(x) page for each file installed on a server system. Squid installs a number of files of various types as listed below. Some work is underway to bring existing texts into matching these standard style of markup. However there are a number of installed files which have no manual at all.
