The event that triggers the package module to be activated is
now retriggered after the package module is initialized but without
any previously registered handlers. Instead only the handlers registered
by the package module will be triggered. The prior event handlers are then
restored after the event is retriggered.
This allows package modules to bind event handlers during initialization
that will be triggered by the same event that caused the package module
intialization to occur. This simplifies the common case of having the same
event cause a package module to initialize and attach.
Migrated strip-trailing-whitespace package to include
a package.cson with a main being a file in the lib directory
instead of the index.coffee at the root of the package.
Allowing root view to be focused was stealing focus away from the
editor whenever a click event made it to the root view. This unnecessary
switching of focus was interfering with the ability to drag tabs.
But if RootView can't be focused, focus ends up being returned to the
document body when there are no focusable elements. This would be fine,
except for the fact that we frequently bind global events on root view,
and so they aren't triggered when events are triggered on the body. We
could just bind all global events on the body, but this would require
us to always attach elements to the DOM during specs, which is a serious
performance killer in specs.
The workaround is in the keymap. When the keymap handles a key event
that was triggered on the body, it triggers the corresponding semantic
event on the root view anyway, so from the event perspective, it's as
if the root view actually had focus. The only place this might fall
down is if someone wants to capture raw key events. But that's the
keymap's job anyway, and we maybe add a hook on the keymap if such a
need ever arises.
