Description

The cmdsynopsis element is used to model the syntax of command line interfaces. Broadly, a command line interface consists of a command followed by a variety of options. These options can be optional or required and may or may not be repeatable.

User expections about how these should be formatted vary by platform and publisher. The $v:arg-… variables are designed to make it easy to adapt to many common forms of presentation. Each contains (usually) a single character used as a delimiter:

Variable	Use in a synopsis	Default^a
`$v:arg-choice-def-close-str`	Follows a default option	]
`$v:arg-choice-def-open-str`	Precedes a default option	[
`$v:arg-choice-opt-close-str`	Follows an optional option	]
`$v:arg-choice-opt-open-str`	Precedes an optional option	[
`$v:arg-choice-plain-close-str`	Follows an option identified as “plain”	(empty string)
`$v:arg-choice-plain-open-str`	Precedes an option identified as “plain”	(empty string)
`$v:arg-choice-req-close-str`	Follows a required option	}
`$v:arg-choice-req-open-str`	Precedes a required option	{
`$v:arg-or-sep`	Separator between options in an “or” group	\|
`$v:arg-rep-def-str`	Identifies a repeatable default option	(empty string)
`$v:arg-rep-norepeat-str`	Identifies a non-repeatable option	(empty string)
`$v:arg-rep-repeat-str`	Identifies an explicitly repeatable option	…

Each of the default characters is placed in an HTML span with the class “cmdpunct”.

A contrived cmdsynopsis appears in Example 1, “An example of a cmdsynopsis”.

   |<cmdsynopsis>
   |   <command>command</command>
   |   <arg choice="plain">
   |      <option>--path <replaceable>PATH</replaceable>
   |      </option>
   |   </arg>
   |   <arg>-opt</arg>
   |   <arg choice="req">-req</arg>
   |   <arg rep="repeat">-D<replaceable>name</replaceable>
   |   </arg>
   |   <group>
   |      <arg choice="plain">-M</arg>
   |      <arg choice="plain">-MD</arg>
   |   </group>
   |</cmdsynopsis>
