Jukebox Plugins are bit of 'add on' software that is controlled by your Juke-box software.

BackGround

In early 2008 a 'standard' set of commands was agreed upon by a few Jukebox software Authors. With some input from other interested parties a Global standard was created. The goal was a plug-in could be created and with a view most if not al functionality would be compatible with any Jukebox software applying this standard.

The standard is known as 'The Jukebox Plug-in System' or JPS

How To Use a Plug-In

Download the plug-in and place it in the 'plugins' subfolder of your Jukebox software. You then need to configure it by.......

Description of the JPS SDK

MAIN PLUGIN CONTROL FUNCTIONS:


PCHAR  Juke_GetPluginInfo()

Return a string with plugin info in the following format ---> "NAME + | + AUTHOR + | + VERSION + | + DESCRIPTION"


int  Juke_Initialize(value)

Inits the plugin when the Jukebox Software starts. Returns 1 when successful.


int  Juke_Shutdown(value)

Shuts down the plugin when the Jukebox Software ends. Returns 1 when successful.


int  Juke_Configure(HWND hWndParent)

Invokes the plugin configuration screen with the jukebox application's window ID. The plugin can use this as it's parent window, so the configuration window can have the current focus. If a jukebox application does not know what it is, this can been set to 0.


PCHAR  Juke_Command(PChar Name, PChar Value)

Sends a command(event) (ASCII formatted) with a name and a value to the plugin. The plugin can return a string pointer to a jukebox software (ASCII formatted) as well (when required).



PLUGIN EVENT COMMANDS:


 Juke_Command("JUKE_PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|valueStr")

This command is used to create(define) a jukebox-specific event which can be sent/received to/from the plugin at any time. One of these commands are sent for each specific event which is defined and are sent to the plugin when the jukebox first starts. The command informs the plugin about "extra" events (which are not defined by the JPS standard).


PLUGIN_EVENT_(name) = jukebox-specific event name

valueStr = text string indicating which types of values are allowed to be sent/received to/from the plugin. This string consists of any of the following text values listed below. Multiple values are space delimited.


ENABLE = allow the user to provide input or invoke change (ie: allow users to delete queued songs)

DISABLE = do not allow user to provide input or invoke change (ex: do not allow users to delete queued songs)

NUMBER = number can be provided (ex: set volume level)

LETTER = letter can be provided (ex: jump to album covers starting with a certain letter).

ON = feature/setting was turned on (ex: mute volume, repeat song)

OFF = feature/setting was turned off (ex: mute volume, repeat song)

KEYDOWN = button has been pressed

KEYUP = button has been released

KEYCLICK = button has been pressed and released


 Juke_Command("JUKE_PLUGIN_EVENT_SEND", "PLUGIN_EVENT_(name)|valueStr")

Sends a previously created(defined) jukebox-specific event to the plugin.


 retValStr =  Juke_Command("JUKE_PLUGIN_EVENT_GET", nullString)

This command is continuously sent to the plugin so the plugin can then return an event string value to indicate an event in which the jukebox software should execute.


retValStr = "PLUGIN_EVENT_(name)|valueStr"



APPLICATION COMMANDS:


Juke_Command("JUKE_APP_GAINFOCUS", nullString)

When the jukebox window becomes the active window in the user's environment


Juke_Command("JUKE_APP_LOSTFOCUS", nullString)

When the jukebox window is no longer the active window in the user's environment


Juke_Command("JUKE_APP_RESTORED", nullString)

When the jukebox application is restored from being minimized


Juke_Command("JUKE_APP_MINIMIZED", nullString)

When the jukebox application is minimized


Juke_Command("JUKE_APP_UNICODE", "TRUE/FALSE")

Whether the Jukebox supports Unicode or not?

Informs the plugin with the jukebox's name.
