Hi Pawel,
   I have attached a patch of unity-china-music-scope with new APIs at https://bugs.launchpad.net/ubuntu/+source/unity-china-music-scope/+bug/1131569. Would you like to sponsor us to upload it?

Regards,
Jonas

Weihua, all,

As you might or might now know, the API changes we planned for 13.04 didn't land on time. We're currently working on finishing the transition to the new API and finishing/polishing some areas (in particular the new Home Scope); there is a Feature Freeze Exception bug filed to get the new stack landed if FFE is approved. In other words, you should port your scope to the new API and have a branch ready for merging when all the base infrastructure we're working on lands, otherwise your scope won't work in 13.04.

The latest API is available in libunity-7.0 branch of libunity, there is a number of scopes ported to it already, plus Unity Dash branch. There are two options for you when porting:
- base your scope on DeprecatedScope* class, which requires only minimal changes to your code;
- inherit your scope on AbstractScope; this requires more changes as you need to implement a number of abstract methods; this is the recommended way.

Both options impose no real changes to "business logic" of scopes. If you choose option #1, you should be able to migrate your code in a matter of few hours tops.

Here is the FFe bug I mentioned:
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1154229
There you'll find all relevant branches, information about ppa etc. Take a look at any of the scopes linked there (for default Ubuntu scopes such as applications, files etc. you need to be looking at -libunity7-compatible branches). 100 scopes such as "wikipedia" and other listed there are using the AbstractScope approach, while our default scopes use DeprecatedScope API.

Kind Regards,
Pawel

Dear Pawel,
    As you wrote in last email:

Until all these changes land in Ubuntu 13.04 repositories (which should happen in ~2-3 weeks), the only way to test a scope against new API is:
- install latest Dee from trunk and libunity-7 branch (don't install system-wide as this would break your current Unity environment; install them in a dedicated subdirectory).
- compile your scope against libunity-7 and run it manually from a terminal.
- test search queries with 'tool/libunity-tool -g' from libunity-7 branch.


    We begin to port unity-china-music-scope to new API. Before I start my work I have some questions:
 1. how to install  latest Dee and libunity-7 branch in a dedicated subdirectory? Do you mean old version and new version can exist together?
 2. how to test search queries with 'tool/libunity-tool -g' from libunity-7 branch?
   
Cheers,
Weihua
