Done.

odd function name because you aren't returning anything. Can you call it
AddExtensionDataToSource?

[Yoyo Zhou, 2012/06/21 21:38:05]

Done.

perhaps use extension->GetBasicInfo

[Yoyo Zhou, 2012/06/21 21:38:05]

I was doing that before, but now I'm not using Value anymore, plus we still have
to convert to string16.

[Evan Stade, 2012/06/21 21:46:06]

extension->GetBasicInfo(true, source_->localized_strings());

[Yoyo Zhou, 2012/06/22 19:20:53]

Ok, good call.
