410 | <para>The <command>call</command> and | |
411 | <command>set-property</command> commands take a signature string | |
412 | followed by a list of parameters formatted as string (for details | |
b938cb90 | 413 | on D-Bus signature strings, see the <ulink |
43dbecd5 LP |
414 | url="http://dbus.freedesktop.org/doc/dbus-specification.html#type-system">Type |
415 | system chapter of the D-Bus specification</ulink>). For simple | |
b938cb90 | 416 | types, each parameter following the signature should simply be the |
43dbecd5 LP |
417 | parameter's value formatted as string. Positive boolean values may |
418 | be formatted as <literal>true</literal>, <literal>yes</literal>, | |
a8eaaee7 | 419 | <literal>on</literal>, or <literal>1</literal>; negative boolean |
43dbecd5 | 420 | values may be specified as <literal>false</literal>, |
a8eaaee7 | 421 | <literal>no</literal>, <literal>off</literal>, or |
43dbecd5 LP |
422 | <literal>0</literal>. For arrays, a numeric argument for the |
423 | number of entries followed by the entries shall be specified. For | |
b938cb90 JE |
424 | variants, the signature of the contents shall be specified, |
425 | followed by the contents. For dictionaries and structs, the | |
43dbecd5 LP |
426 | contents of them shall be directly specified.</para> |

428 | <para>For example, | |
429 | <programlisting>s jawoll</programlisting> is the formatting | |
430 | of a single string <literal>jawoll</literal>.</para> | |
431 | ||
432 | <para> | |
433 | <programlisting>as 3 hello world foobar</programlisting> | |
434 | is the formatting of a string array with three entries, | |
435 | <literal>hello</literal>, <literal>world</literal> and | |
436 | <literal>foobar</literal>.</para> | |
437 | ||
438 | <para> | |
439 | <programlisting>a{sv} 3 One s Eins Two u 2 Yes b true</programlisting> | |
440 | is the formatting of a dictionary | |
441 | array that maps strings to variants, consisting of three | |
442 | entries. The string <literal>One</literal> is assigned the | |
443 | string <literal>Eins</literal>. The string | |
b938cb90 | 444 | <literal>Two</literal> is assigned the 32-bit unsigned |
43dbecd5 LP |
445 | integer 2. The string <literal>Yes</literal> is assigned a |
446 | positive boolean.</para> | |
447 | ||
448 | <para>Note that the <command>call</command>, | |
449 | <command>get-property</command>, <command>introspect</command> | |
450 | commands will also generate output in this format for the returned | |
451 | data. Since this format is sometimes too terse to be easily | |
452 | understood, the <command>call</command> and | |
453 | <command>get-property</command> commands may generate a more | |
454 | verbose, multi-line output when passed the | |
455 | <option>--verbose</option> option.</para> | |

464 | <para>The following two commands first write a property and then | |
