+ <title>Parameter Formatting</title>
+
+ <para>The <command>call</command> and
+ <command>set-property</command> commands take a signature
+ string followed by a list of parameters formatted as string
+ (for details on D-Bus signature strings see the <ulink
+ url="http://dbus.freedesktop.org/doc/dbus-specification.html#type-system">Type
+ system chapter of the D-Bus specification</ulink>). For
+ simple types each parameter following the signature should
+ simply be the parameter's value formatted as
+ string. Positive boolean values may be formatted as
+ <literal>true</literal>, <literal>yes</literal>,
+ <literal>on</literal>, <literal>1</literal>; negative
+ boolean values may be specified as <literal>false</literal>,
+ <literal>no</literal>, <literal>off</literal>,
+ <literal>0</literal>. For arrays, a numeric argument for the
+ number of entries followed by the entries shall be
+ specified. For variants the signature of the contents shall
+ be specified, followed by the contents. For dictionaries and
+ structs the contents of them shall be directly
+ specified.</para>
+
+ <para>For example,
+ <programlisting>s jawoll</programlisting> is the formatting
+ of a single string <literal>jawoll</literal>.</para>
+
+ <para>
+ <programlisting>as 3 hello world foobar</programlisting>
+ is the formatting of a string array with three entries,
+ <literal>hello</literal>, <literal>world</literal> and
+ <literal>foobar</literal>.</para>
+
+ <para>
+ <programlisting>a{sv} 3 One s Eins Two u 2 Yes b true</programlisting>
+ is the formatting of a dictionary
+ array that maps strings to variants, consisting of three
+ entries. The string <literal>One</literal> is assigned the
+ string <literal>Eins</literal>. The string
+ <literal>Two</literal> is assigned the 32bit unsigned
+ integer 2. The string <literal>Yes</literal> is assigned a
+ positive boolean.</para>
+
+ <para>Note that the <command>call</command>,
+ <command>get-property</command>,
+ <command>introspect</command> commands will also generate
+ output in this format for the returned data. Since this
+ format is sometimes too terse to be easily understood, the
+ <command>call</command> and <command>get-property</command>
+ commands may generate a more verbose, multi-line output when
+ passed the <option>--verbose</option> option.</para>

+ service. The name of the property is
+ <literal>LogLevel</literal> on the

+ <title>Terse and Verbose Output</title>
+
+ <para>The following two commands read a property that
+ contains an array of strings, and first show it in
+ terse format, followed by verbose format:</para>
