Powerlaunch Re-implementation
suggestion: very simple vala daemon which is essentially a object/plugin loader, providing some degree of conflict-prevention, run a glib main loop and let the behaviour implement themselves as they want
Use Cases
Needed
Eg Dim screen on Idle when the device is 'locked' the key handling connections aren't made *apart* from long press on the power
conditional and grouped instructions
Proposed Design
Vala based daemon which is driven by a validated machine parseable config (cf http://live.gnome.org/Vala/DBusClientSamples)
Glib plugins to this daemon present UI-facing methods.
Python config parser to generate validated machine parseable config from a human readable (or gui managed) description. Essentially joining signals and slots from the plugins; possibly with conditionals.
The daemon doesn't have all the complex config parsing stuff resident all the time; also need to avoid inventing a scripting language on top that wires together the stuff.
Implementation Proposal
Initial implementation of the outline design using a python launcher and even plugins then review the use cases and see how it impacts memory usage. If we find we can keep it simple then we port it to vala.
