Note: This development section is only of any real interest to Jukebox software authors and Plug-in authors. Any details on how to use a plug-in will be provided with that plug-in.
 +
 
 +
<b><u>MAIN PLUGIN CONTROL FUNCTIONS:</u></b>
 +
 
 +
 
 +
PCHAR  Juke_GetPluginInfo()<br>
 +
Return a string with plugin info in the following format --->
 +
"NAME + | + AUTHOR + | + VERSION + | + DESCRIPTION"
 +
 
 +
 
 +
int  Juke_Initialize(value)<br>
 +
Inits the plugin when the Jukebox Software starts.  Returns 1 when successful.
 +
 
 +
 
 +
int  Juke_Shutdown(value)<br>
 +
Shuts down the plugin when the Jukebox Software ends.  Returns 1 when successful.
 +
 
 +
 
 +
int  Juke_Configure(HWND hWndParent)<br>
 +
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)<br>
 +
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).
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
<b><u>PLUGIN EVENT COMMANDS:</u></b>  (double-quotes are not included in the text string which is sent)
 +
 
 +
 
 +
  Juke_Command(JUKE_PLUGIN_EVENT_CREATE, "PLUGIN_EVENT_(name)|createValueStr")<br>           
 +
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).
 +
 
 +
 
 +
<b><i>PLUGIN_EVENT_(name)</i></b> = jukebox-specific event name
 +
 +
<b><i>createValueStr</i></b> = 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.                
 +
 
 +
 
 +
<i>ENABLE</i>  = allow the user to provide input or invoke change  (ie: allow users to delete queued songs)
 +
 
 +
<i>DISABLE</i>  = do not allow user to provide input or invoke change (ex: do not allow users to delete queued songs)
 +
 
 +
<i>NUMBER</i>  = number can be provided (ex: set volume level)
 +
 
 +
<i>LETTER</i>  = letter can be provided (ex: jump to album covers starting with a certain letter).  
 +
 
 +
<i>ON</i>      = feature/setting was turned on (ex: mute volume, repeat song)
 +
 
 +
<i>OFF</i>      = feature/setting was turned off (ex: mute volume, repeat song)
 +
 
 +
<i>KEYDOWN</i>  = button has been pressed
 +
 
 +
<i>KEYUP</i>    = button has been released
 +
 
 +
<i>KEYCLICK</i> = button has been pressed and released
 +
 
 +
 
 +
<u>Examples:</u>
 +
 
 +
1) To indicate whether something is on or off then the following command would be created:
 +
<i>JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|ON OFF")</i>
 +
 
 +
 
 +
2) To indicate a number or letter can be associated with the event:
 +
<i>JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|NUMBER LETTER")</i>
 +
 
 +
 
 +
3) To indicate you can enable or disable (like lights) something as well as indicating you can receive some keyEvent for it:
 +
<i>JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|ENABLE DISABLE KEYDOWN KEYUP KEYCLICK")</i>
 +
 
 +
 
 +
4) Now, "just for fun" lets say there is an event which allows the plugin to enable/disable it, also allows it to enter a number and a letter:
 +
<i>JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|ENABLE DISABLE NUMBER LETTER")</i>
 +
 
 +
 
 +
  Juke_Command("JUKE_PLUGIN_EVENT_SEND", "PLUGIN_EVENT_(name)|sendValueStr")<br>
 +
Sends a previously created/defined jukebox-specific event to the plugin.
 +
 
 +
 
 +
<b><i>PLUGIN_EVENT_(name)</i></b> = event name previously created by the "JUKE_PLUGIN_EVENT_CREATE" command
 +
 +
<b><i>sendValueStr</i></b> = one of the "createValueStr" values listed above                 
 +
 
  
==How To Write your own Plug-In==
+
  retValStr = Juke_Command("JUKE_PLUGIN_EVENT_GET", nullString)<br>
 +
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.
  
To write a Plug-in you need to obtain a copy of the 'Juke-Box Plug-In SDK'
+
'''Please Note: Some jukebox software does not like " in the returned string, so do NOT add them here'''
  
The following is a list of supported Functions:
 
  
'''PCHAR Juke_GetPluginInfo();'''
+
<b><i>retValStr</i></b> = text string in the following format --> "PLUGIN_EVENT_(name)|valueStr"
Return a string contaion this info with this format:
 
PLUGIN_NAME + '|' + PLUGIN_AUTHOR + '|' + PLUGIN_VERSION + '|' + PLUGIN_DESCRIPTION
 
  
'''Juke_Command(Name:PChar; Value:PChar):PChar;'''
 
Sending a string (UTF8 or ASCII formatted) with a name and a value, and some commands might return a string pointer to a jukebox softare (also UTF8 or ASCII formatted).
 
  
note: Visual Basic 6 can get returned strings using a little dll I made. Look to the bottom of the first thread.
 
  
  
'''CONFIGURATION COMMANDS:'''
 
  
'''Juke_Command("JUKE_KEY_EVENT_CREATE","KEY_EVENT_NAME")'''
 
This command is required before JUKE_PLUGIN_CONFIGURE is invoked. This make sure a plugin can "listen" to a KEY_EVENT command from the Jukebox Software and example effect a sound effect to a KEY_EVENT.
 
  
A Jukebox Software can create any KEY_EVENT commands that can been controlled by the user (also like a keybinding).
+
<b><u>APPLICATION COMMANDS:</u></b>  (double-quotes are not included in the text string which is sent)
  
Only KEY_EVENT commands (keybindning) is needed for the plugin to known, so they can used for various things like LedWiz, Sound, Remote controlling and other things.
 
  
'''Juke_Command("JUKE_PLUGIN_CONFIGURE","WINDOW_HWND")'''
 
Invoke plugin configuration screen with the Plugin Mangager WINDOW ID. The Plugin can use as its parent windows, so the configuration window can have the current focus.
 
  
If a Jukebox Application dosent know what it is, this can been set to 0.
+
Juke_Command("JUKE_APP_GAINFOCUS", nullString)<br>
 +
When the jukebox window becomes the active window in the user's environment
  
  
'''APPLICATION COMMANDS:'''
+
Juke_Command("JUKE_APP_LOSTFOCUS", nullString)<br>
 +
When the jukebox window is no longer the active window in the user's environment
  
'''Juke_Command("JUKE_APP_OPENED","")'''
 
The Jukebox software have just started.
 
  
'''Juke_Command("JUKE_APP_CLOSED","")'''
+
Juke_Command("JUKE_APP_RESTORED", nullString)<br>
The Jukebox software have just closed.
+
When the jukebox application is restored from being minimized
  
'''Juke_Command("JUKE_APP_UNICODE","TRUE or FALSE")'''
 
Does the Jukebox support Unicode or not? Then the UTF8 formatted strings can been used.
 
  
'''Juke_Command("JUKE_APP_HOST","SOFTWARE NAME")'''
+
Juke_Command("JUKE_APP_MINIMIZED", nullString)<br>
The Jukebox software name.
+
When the jukebox application is minimized
  
If a jukebox application support UNICODE, the arguments would been JUKE_APP_HOST_UNICODE his string would been used, otherwice empty. If the Jukebox Software is not used any unicode string, that would been no need to convert UTF8 strings by both plugin and jukebox software.
 
  
!! Plugin Writers: Please dont reject other jukebox software, if you have a favorit !!
+
Juke_Command("JUKE_APP_UNICODE", "TRUE or FALSE")<br>
 +

'''SONGLIST COMMANDS:'''
+

 +
Informs the plugin with the jukebox's name.
  
  
For Jukebox Authors: If the song contain a | char (I never seen that), remove that before send the string.
 
  
  
Juke_Command("JUKE_SONGLIST_ADD_SONG",
 
"system|postition|title|artist|album|genre|totalDuration|TrackNr|AlbumNr|more")
 
Add a song into that position in the queue.
 
  
Some Jukebox Software might add a song directly as a first song, so it play directly. Here set a value to 0.
+
<b><u>SONGLIST COMMANDS:</u></b>  (double-quotes are not included in the text string which is sent)
If a positionis to big, it would just added next to the queue.
 
  
Info about arguments:
 
  
    * Auto means if it was added by the "USER" or by "SYSTEM".
 
    * TrackNr and AlbumNr is the same values gave by DIGIT COMMANDS.
 
    * Some songinfo "tags" might been empty if not used.
 
    * Some songs might not even contain TotalDuration if it is unknown.

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

File:Http://www.jukeplugsys.com/logo.png

BackGround

In early 2008 a standard set of commands was designed by Space Fractal (MultiJuke) with a goal of allowing plugIns to be created which would be compatible with any jukebox software which supports this standard. With some input from other interested parties (loadman and headkaze) a global standard was created.

The standard is known as the Jukebox PlugIn System (JPS) (or JukePlugSys).


Jukebox software which supports the JPS standard are listed below:

How To Use a Plug-In

Download the plug-in and place it in the 'plugins' subfolder of your jukebox software. You can then configure the plugin with your specific requirements by going into the jukebox software, locating the plugin and clicking the provided configuration button.


JPS SDK description

Note: This development section is only of any real interest to Jukebox software authors and Plug-in authors. Any details on how to use a plug-in will be provided with that plug-in.

MAIN PLUGIN CONTROL FUNCTIONS:


PCHAR  Juke_GetPluginInfo()

int  Juke_Shutdown(value)

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


int  Juke_Configure(HWND hWndParent)

PCHAR  Juke_Command(PChar Name, PChar Value)

PLUGIN EVENT COMMANDS: (double-quotes are not included in the text string which is sent)


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

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

createValueStr = 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


Examples:

1) To indicate whether something is on or off then the following command would be created: JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|ON OFF")


2) To indicate a number or letter can be associated with the event: JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|NUMBER LETTER")


3) To indicate you can enable or disable (like lights) something as well as indicating you can receive some keyEvent for it: JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|ENABLE DISABLE KEYDOWN KEYUP KEYCLICK")


4) Now, "just for fun" lets say there is an event which allows the plugin to enable/disable it, also allows it to enter a number and a letter: JukeCommand("PLUGIN_EVENT_CREATE", "PLUGIN_EVENT_(name)|ENABLE DISABLE NUMBER LETTER")


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

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


PLUGIN_EVENT_(name) = event name previously created by the "JUKE_PLUGIN_EVENT_CREATE" command

sendValueStr = one of the "createValueStr" values listed above


 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.
