The show begins at first-track and then uses events (GPIO, keypresses etc.) to link to other tracks via their symbolic names
If using 'call' keeps a record of the tracks it has visited so the 'return' command can go back.
Executes timeout-track if no user input is received.
links are of the form:
symbolic-name command [track-ref]
link commands:
call <track-ref> play track-ref and add it to the path
return - return 1 back up the path removing the track from the path, stops at home-track.
return n - return n tracks back up the path removing the track from the path, stops at home-track.
return <track-ref> return to <track-ref> removing tracks from the path
home - return to home-track removing tracks from the path
jump <track-ref-> - play trck-ref forgetting the path back to home-track
goto <track-ref> - play track-ref, forget the path
exit - end the hyperlink show
null - inhibits the link defined in the show with the same symbolic name.

"""
Aimed at touchscreens but can be used for any purpose where the user is required to follow hyperlinks between tracks
Profiles for media tracks (message, image, video, audio ) specify links to other tracks
In a link a symbolic name of an input is associated with a track-reference
The show begins at a special track specified in the profiile called the First Track and moves to other tracks
- when a link is executed by a input event with a specified symbolic name
- at the natural end of the track using the special pp-onend symbolic name
If using the 'call' link command PP keeps a record of the tracks it has visited so the 'return' command can go back.
Executes timeout-track if no user input is received (includes pp-onend but not repeat)
There is a another special track with Home Track. The home command returns here and the 'return n' command will not go back past here.
This was designed to allow the timeout to go back to First Track which would advertise the show.
Once the user had been enticed and clicked a link to move to Home pressing home or return would not return him to First Track
You can make the Home Track and the First Track the same track if you want.
You may want a track, if it is a video or audio track, to repeat. You can use repeat for this and it will not cancel the timeout.
Image and message tracks can have a zero duration so they never end naturally so repeat is not required.
links are of the form:
symbolic-name command [track-ref]
link commands:
call <track-ref> play track-ref and add it to the path
return - return 1 back up the path removing the track from the path, stops at home-track.
return n - return n tracks back up the path removing the track from the path, stops at home-track.
return <track-ref> return to <track-ref> removing tracks from the path
home - return to home-track removing tracks from the path
jump <track-ref-> - play track-ref forgetting the path back to home-track
goto <track-ref> - play track-ref, forget the path
repeat - repeat the track
exit - end the hyperlink show
null - inhibits the link defined in the show with the same symbolic name.
reserved symbolic names
pp-onend command - pseudo symbolic name for end of a track
interface:
* __init__ - initlialises the show
* play - selects the first track to play (first-track)
* input_pressed, - receives user events passes them to a Shower/Player if a track is playing,
otherwise actions them depending on the symbolic name supplied
* exit - stops the show from another show
* terminate - aborts the show, used whan clsing or after errors
* track_ready_callback - called by the next track to be played to remove the previous track from display
* subshow_ready_callback - called by the subshow to get the last track of the parent show
* subshow_ended_callback - called at the start of a parent show to get the last track of the subshow

"""
Aimed at touchscreens but can be used for any purpose where the user is required to follow hyperlinks between tracks
Profiles for media tracks (message, image, video, audio ) specify links to other tracks
In a link a symbolic name of an input is associated with a track-reference
The show begins at a special track specified in the profiile called the First Track and moves to other tracks
- when a link is executed by a input event with a specified symbolic name
- at the natural end of the track using the special pp-onend symbolic name
If using the 'call' link command PP keeps a record of the tracks it has visited so the 'return' command can go back.
Executes timeout-track if no user input is received (includes pp-onend but not repeat)
There is a another special track with Home Track. The home command returns here and the 'return n' command will not go back past here.
This was designed to allow the timeout to go back to First Track which would advertise the show.
Once the user had been enticed and clicked a link to move to Home pressing home or return would not return him to First Track
You can make the Home Track and the First Track the same track if you want.
You may want a track, if it is a video or audio track, to repeat. You can use repeat for this and it will not cancel the timeout.
Image and message tracks can have a zero duration so they never end naturally so repeat is not required.
links are of the form:
symbolic-name command [track-ref]
link commands:
call <track-ref> play track-ref and add it to the path
return - return 1 back up the path removing the track from the path, stops at home-track.
return n - return n tracks back up the path removing the track from the path, stops at home-track.
return <track-ref> return to <track-ref> removing tracks from the path
home - return to home-track removing tracks from the path
jump <track-ref-> - play track-ref forgetting the path back to home-track
goto <track-ref> - play track-ref, forget the path
repeat - repeat the track
exit - end the hyperlink show
null - inhibits the link defined in the show with the same symbolic name.
reserved symbolic names
pp-onend command - pseudo symbolic name for end of a track
interface:
* __init__ - initlialises the show
* play - selects the first track to play (first-track)
* input_pressed, - receives user events passes them to a Shower/Player if a track is playing,
otherwise actions them depending on the symbolic name supplied
* exit - stops the show from another show
* terminate - aborts the show, used whan clsing or after errors
* track_ready_callback - called by the next track to be played to remove the previous track from display
* subshow_ready_callback - called by the subshow to get the last track of the parent show
* subshow_ended_callback - called at the start of a parent show to get the last track of the subshow

"""
Aimed at touchscreens but can be used for any purpose where the user is required to follow hyperlinks between tracks
Profiles for media tracks (message, image, video, audio ) specify links to other tracks
in a link a symbolic name of an input is associated with a track-reference
The show begins at first-track and then uses events (GPIO, keypresses etc.) to link to other tracks via their symbolic names
If using 'call' keeps a record of the tracks it has visited so the 'return' command can go back.
Executes timeout-track if no user input is received.
links are of the form:
symbolic-name command [track-ref]
link commands:
call <track-ref> play track-ref and add it to the path
return - return 1 back up the path removing the track from the path, stops at home-track.
return n - return n tracks back up the path removing the track from the path, stops at home-track.
return <track-ref> return to <track-ref> removing tracks from the path
home - return to home-track removing tracks from the path
jump <track-ref-> - play trck-ref forgetting the path back to home-track
goto <track-ref> - play track-ref, forget the path
exit - end the hyperlink show
null - inhibits the link defined in the show with the same symbolic name.
reserved symbolic names
pp-onend command - pseudo symbolic name for end of a track
