Current status
- Targeted release: 0.88
- Last updated: Thu Jul 9 00:36:45 UTC 2009
- Percentage of completion: 0%
Detailed Description
This code follows Design Team/Proposals/Journal mockups.
UI modes
Unified Browser supports plugins for different UI modes:
- Journal objects-centric plugin
- Books plugin, Calibre-like(or so) for browsing books
- Audio plugin for browsing audio files
- Video plugin for browsing video files
- ..
So, we could have plugins for different purposes i.e. Journal plugin could be very common/simple but something like plugin for Books/Video/etc can have some special UI features(that look redundant in Journal plugin).
For sugar-0.86+, Journal will load all installed plugins and provide possibility to switch between them, for <0.86 plugins will be formed in separated activities.
For sugar-0.86+, Journal plugin will be packaged with sugar, other plugins could be packaged into activities and have separate code base. In 0.86+ environment, these activities will use plugins engine from current sugar, for <0.86 environments(and for 0.86+ glucose releases when plugin uses newer engine), plugins engine will be packaged into activity bundles.
NOTE Separate activities is not a task for this feature proposal.
Plugins engine
Browser provides backwards compatible and versioned plugins engine API:
- v0 engine for glucose-0.82/0.84
- v1 engine for glucose-0.86(+)
Engine provides all necessary functionality for plugins:
- TreeViewModel as a source of objects; so, all pulugins should use TreeViewModel for list widgets
- for local objects(rich client for <0.86 and thin client for >=0.86)
- for remote p2p objects
- for remote server objects
- aggregated sources(combine several sources)
- UI widgets, like TreeView, TableView, tag clouds etc.
- shell related procedures(like activate objects)
Benefit to Sugar
Browsing different types of sugar object looks the same in many cases(search, tagging etc.). So, keep unified code base and do not split it could be useful idea.
Scope
- affects Journal code in sugar package
- adds new activity for <0.86 releases
- Datastore API should provide tags functionality for 0.86+
How To Test
In progress..
User Experience
All objects browsing features will look equally. It should mean that users will reuse theirs Journal experience in browsing books for example.
Dependencies
For >=0.86, all functionality will come from sugar package, for <0.86 it will be packaged in activity.
Contingency Plan
None necessary, revert to previous release behaviour.
