Re: OMG: the LeoApp class needs no outline data!

[pimgeek]

Sounds very promising!

A related question to ask:

Can I turn Leo Editor App into a Leo Data Server by install the leoflexx 
plugin? (and then in theory I can access the data via Web Browser from 
every machine on the internet) :-O

Recently I try to bind Leo Data to a one-page WebApp via package eel 
, and I also noticed package flexx 
. Is that related to leoflexx.py? :-)

Re: How to get viewrendered pane size?

[pimgeek]

Thanks for your quick reply!

The problem is, I want to hide / show vr pane but the default Alt-0 method 
always "breaks the layout"  after hiding and re-showing vr pane, it 
moved to an unexpected location.

I have figured out this solution by trail-and-error, is there any simpler 
ways to do it? :-)

# get lowercase leo filename
> this_filename = c.fileName().lower()
> # get vr obj
> vr = g.app.pluginsController.loadedModules['leo.plugins.viewrendered'].
> controllers[this_filename]
> curr_vr_width = vr.width()
> curr_vr_height = vr.height()
> # change pane size
> vr.change_size(...)

OMG: the LeoApp class needs no outline data!

[Edward K. Ream]

None of the outline-related data structures mentioned in leoflexx.py 
progress report 3 
 are 
needed!!

Proof: The dicts returned by the app.redraw and app.send_children_to_tree 
actions contain *all* the data the tree class is ever going to need.  If 
not, I'll add more.

The LeoApp class itself never needs these data because *LeoApp is on the 
python side*.  app.make_redraw_dict has full access to real c and p objects.

End of code, end of performance worries.  It takes 0.000 seconds *not *to 
compute something ;-) app.make_redraw_dict itself takes 0.006 seconds on my 
machine.

I am on the "put one in, get more than one out" part of the learning curve.

The changeover to the new scheme will happen today or tomorrow.  You can 
test the new code now by typing "redraw" (without the quotes) in the 
minibuffer.

 To this should be added:

'headline': p.h,

This is good for debugging, and perhaps for other uses.

Well, only a fool would use a lisp-like list. cons, cdr, caddr anyone? 

Recent revs add app.make_redraw_*dict* and its helpers, including 
app.dump_redraw_*dict*. These were even simpler than I had hoped.  They 
lead to a big Aha, which I'll trumpet in a separate thread.

Probably the easiest thing is to arrange the panes as you want them,
then right click the divider between panes (doesn't matter which one),
select 'Save Layout', and give the layout a name.  It should persist
after that.
