[Sugar-devel] Change request: Fix open with API

[Tony Anderson]

Thanks James and Sam for your replies.

The references to Rainbow Security model are a bit confusing. The 
Rainbow model was dropped by the second G1G1 as I recollect. As far as I 
can tell, Browse launches child processes (pdfviewer). These typically 
are represented in the frame by a grey circle.

I apologize on the argparse issue, I am still with 13.2. I was confused 
by the documentation: 
http://wiki.sugarlabs.org/go/Features/Start_activity_from_another_activity

"An activity can start other activity by:

  * knowing the activity ID - starts that specific activity"

I assume that is a typo and bundle_id is meant.

By having sugar-launch pass the -u (uri) and -o (object_id) options, it 
is possible now (and possibly since 0.82) to launch an activity by 
activity bundle_id either with a Journal object or a file from the 
Documents directory (visible in Journal) or a USB key (also visible in 
Journal).  I have been using the -o and -u options in sugar-launch for 
at least five years. This was discussed when this feature was first 
proposed.

In effect, the api added to 106 is simply an alternate way to perform 
existing functions.
