The more I think about it, the more I think Leo needs an automated playback
capability. I had some initial thoughts in the thread, "PyOhio Leo Video
up on youtube",
https://groups.google.com/forum/?fromgroups=#!topic/leo-editor/nmBweM3wI3o.
There as several immediate applications for automated playback:
1. As a helper for those preparing demos of Leo. It eliminates the need to
think, talk and type at the same time ;-) The hope is that the narrator
would be more comfortable and relaxed during the recording, but perhaps
that is wishful thinking.
2. As an automated, scripted, demo of what Leo can do. You could even
imagine the quickstart.leo would "create itself" when it was opened. You
would simply need to start the demo when the file was opened!
As I was thinking about playback, I considered how the playback would draw
attention to various parts of the screen. In other words, we need
something akin to the big red arrows in the Leo slideshows. One easy way to
do this would be with a DialogWithImage call, that would pop up a dialog
showing, say, a magnified image of a dirty icon box. Depending on options,
the dialog might go away after a few seconds, or remain until the use hits
any key.
The main question is, how easy will it be to create and edit playbacks?
I'm not sure. Any such playback capability would essentially be a
(detailed!) script. We can imagine a script that is essentially Python:
Something like:
goto_sibling_node(<<node name>>)
dialog(<<dialog name>>,<< when dismissed>>)
edit_headline
type_individual_letters('This is the headline',<<delay between letters>>)
type_text('This is the headline')
insert_sibling_node()
insert_child_node()
select_find_tab()
etc! etc!
Leo already has most of the capability go generate this as we use Leo:
it's the so-called "lossage" history in k.masterKeyHandler. I'm thinking
that there is no urgent need to capture the mouse: we might as well
demonstrate mouseless Leo!
Actually, we might forgo capturing actions altogether, and just write the
script directly. We'll have to see whether that makes sense.
Your comments, please, Amigos.
