[Sugar-devel] [PATCH] Add clone to view-source submenu
Walter Bender
walter at sugarlabs.org
Mon Aug 15 16:44:32 EDT 2011
From: Walter Bender <walter.bender at gmail.com>
This patch adds a Clone submenu to the view source toolbar, enabling the
cloning of an activity for end-user modification.
As per the design team meeting, this patch includes the generation of an
.xo bundle to be copied to the Journal of the cloned activity.
One known bug not addressed here is that if the bundle_id is missing, the
cloning will be successful, but the resultant activity will not launch.
---
Note: This is a modification of an earlier version of the patch. In this
an emblem is overlaid onto the cloned activity icon. Also a logic error has
been fixed where cloning would fail if the overlay icon was not found.
Note: This version of the patch uses 'duplicate' rather than 'clone' as
per the discussion in the 2011-08-15 Design Team meeting and has a dependency
on the newly committed edit-duplicate icon.
Note: Regeneration of patch would not apply without applying the sugar-toolkit
view-source patch first. This version applies stand-alone.
