It's going to be messy, but if you are getting your hands dirty anyway
heres what I would really like to see implemented:
- Abstracted status object with generic status fields like
CurrentModule, Progress, State (playing, paused, etc).
- Module is subclassed with extra status fields depending on which
module we are actually in and so classes with awareness of the module
specific fields can delve more deeply to find out what the current
status is. For example the music might currently be "Status:playing"
and "Progress: 15%", but an LCD panel would find it useful to know that
the user was browsing the playlist editor and what the items on the
screen were so that it could replicate them on the LCD panel
Does this make sense? Otherwise we will need to write the same custom
"status" code for each module, and probably repeat it for each kind of
device (LCD panel, web remote control, etc).
I think there are probably more fields which would be useful in the top
level status object, but I personally think that I could write a basic
remote control app knowing just those basic fields, ie which module we
were currently in, Status enum (like play, paused), and current
progress. Perhaps a "current play item" field would be useful as well?
These seem to apply to nearly all modules although it's strained a
little with some of them. Consider the weather module which basically
feels like a slideshow - we can use play/paused state here, and either
the "progress" or "current play item" ends up telling the remote app
which particular page we are on right now.
I don't think such a change needs to be a big change, at least for phase
one just to get a rough status object in place? I hope some folks like
Isaac might pour scorn on the concept before I or others waste some time
