What does this mean?
iPeng now features the “ipeng” CLI command that can be used to extend iPeng’s functionality. Right now, it is supported by the “NowPlaying” screen to add plugins to the “left” page and can be used to configure the shortcut button on the bottom of the screen. And most important: The same mechanism will be used by the native iPeng application for iPhone and iPod touch so any plugin supporting this for the web skin will also appear on the native app. The native app will also use this to generate extended browse pages.
The data being handed to iPeng through the iPeng command is specified as follows:
<!-- An iPeng XML file / parameter description using DTD format -->
<!-- the content of the config file is contained in a <configuration> element -->
<!ELEMENT configuration ( section* )>
<!-- The configuration is made up of sections which in turn are entirely made up of one or more subsections --> <!ELEMENT section ( subsection* )>
<!-- Each section has an "id" attribute determining the type of content it contains, as in <section id = "nowplaying">. This attribute is used by iPeng to select the content valid for a certain page. currently defined values are: browse - for browse pages nowplaying - for the NowPlaying page toolbar - for toolbar icons --> <!ATTLIST section id ( "browse"|“nowplaying"|"toolbar"|#PCDATA )> <!-- A <subsection id="..."> represents a row on the "NowPlaying" screen or a Browse screen or a context on the Toolbar. A subsection is not a command, so no action is assigned to a subsection. A Subsection may have a name and/or icon, these will be shown to the left of the <command> content and will not be selectable. <name> and <icon> will be ignored for the toolbar. A subsection on the toolbar represents a context parameter and can be used to determine, when a command is being shown. There are the following predefined contexts: * - default items valid in all contexts. Context specific commands take precedence default - a context that will be used when no context parameter is being set, e.g. when a plugin or page is not aware of the toolbar context functionality. home - the home screen browse - iPengs standard browse screens playlists - playlist browse screen xmlbrowse - the xmlbrowse context, typically, this is being used for internet radios A plugin may define it's own contexts. Subsections are sorted by the <weight> parameter. A subsection is made up of one or more commands --> <!ELEMENT subsection ( weight?, <!-- --> name?, <!-- --> icon?, <!-- --> command* )> <!-- Each subsection has an arbitrary id that is being used to group commands together. If more than one plugin registers a subsection under the same name, these subsections will be merged and interpreted like one subsection. <ATTLIST subsection id ( #PCDATA )> <!-- A subsection is made up of one or more commands. Commands represent an element that can be selected and will result in an action. They result is dependent on the type and the section. Section "nowplaying": <type>: "command" - a command that will be executed either through the CLI or by calling an url - through ajaxRequest. "content" - a command that will be executed through ajaxUpdate; the result will be shown in - the "plugin content" page on the NowPlaying screen. Section "browse": <type> "command" - a command that will be executed through "ajaxRequest" or the CLI. "content" - a url of a new page that will be loaded or a CLI command that will return - XML content to be rendered in a browse page. Format tbd. Section "toolbar": <type> has no meaning and is ignored. --> <!ELEMENT command ( weight?, <!-- --> position?, <!-- --> description?, <!-- --> requireplugins?, <!-- --> defaultenabled?, <!-- --> type, <!-- --> name?, namestring? <!-- --> icon?, selectedicon?, <!-- --> html?, <!-- --> width?, height?, <!-- --> parameters*, <!-- --> url?|cli? )> !ATTLIST command id ( #PCDATA )> <!-- an id that will be used to identify the command --> <!ELEMENT description ( #PCDATA )> <!-- a description being used to identify the command on the settings page --> <!ELEMENT requireplugins ( #PCDATA )> <!-- names of plugins required to enable the command. --> <!-- If the plugin is not present, the command will not be shown --> <!ELEMENT defaultenabled ( "0" | "1")> <!-- if set to "0" the command will be disabled by default --> <!ELEMENT weight ( #PCDATA )> <!-- a numeric value being used to sort the commands --> <!ELEMENT position ( #PCDATA )> <!-- a numeric value defining the position on the toolbar or in the list --> <!-- on the NowPlaying screen.

May include a Hash for positioning (#...)--> <!ELEMENT cli ( #PCDATA )> <!-- a CLI command to be executed. only one of <cli> OR <url> --> <!-- may be used. If both are present, url takes precedence. --> <!-- With each commands a set of parameters can be specified that will be filled by iPeng and handed to the command. Generally the tag specified identifies the parameter while the value of the tag specifies the name under which a parameter will be added. So "<album_id>record</album_id>" will result in the album ID being passed to the command as a "record" parameter, as in "record=xxxx". A special Parameter is "other" which gives an additional parameter string that will be passed "as is". There may be more than one "other" parameter. Allowed parameters are: <other> - any string, can also be other0, other1,... <album> - the current album name <album_id> - the current album id <artist> - the current artist name <artist_id> - the current artist id <genre> - the current genre name <genre_id> - the current genre id <title> - the current track title <id> - the current track id <index> - the index of the current track in the playlist <playlist> - the name of the current playlist, currently not supported <playlist_id> - the id of the current playlist, currently not supported <player> - the id of the active player --> <!ELEMENT parameters ( other|album|album_id|artist|artist_id|genre|genre_id| <!-- --> title|id|index|playlist|playlist_id|player )>
