​Excellent.  'icons' is obviously a much better key into p.v.u.

Thank you so much, Terry.   

That really helps clarify.  

I'll switch to 'icons' in my code.   Will also update my full build from the 
trunk in the next day or two well.

I see you were following an example that tested 'lineYOffset'.  Also, I
see no use of 'lineYOffset' in the code base except setting to 3 when
icons are added and 0 when they're deleted, I think it's debris from
the old Tk interface.

So I've deleted all reference to it, and you'll need to use 

  aList = [p.copy() for p in c.all_unique_positions()
   if 'icons' in p.u]

for getting the list of nodes with icons.

Hope that's not breaking too much of anything for anyone - banking on
most people other that Edward ;-) picking 'icons' rather than
'lineYOffset' as a text target :-)

What you're doing makes sense, you're just tripping over a bit of cruft
in the code base.  Todo.py uses icons, but icons are separate, so
delete Todo isn't relevant.  The problem is that 

c.editCommands.deleteNodeIcons(p=p)

doesn't clean up p.u as fully as it might:

insert an icon...

V {'icons': [{'file': 
u'/mnt/usr1/usr1/home/tbrown/t/Package/leo/git/leo-editor/leo/Icons/Tango/16x16/devices/battery.png',
'on': 'VNode',
'relPath': u'Tango/16x16/devices/battery.png',
'type': 'file',
'where': 'beforeHeadline',
'xoffset': 2,
'xpad': 1,
'yoffset': 0}],
 'lineYOffset': 3}

delete all icons

V {'lineYOffset': 0}

c.editCommands.deleteNodeIcons(p=p) should delete both 'icons' *and*
'lineYOffset' from p.u, but it leaves that remnant.  If you'd tested
'icons' instead of 'lineYOffset', you'd have seen no problem.  I guess
it is setting it back to zero, but seeing that's the default / assumed,
deleting it would be cleaner, I'll make that change on trunk, but you
can just check 'icons' instead as a work around / avoidance.

Re: Code academy: icons

2016-02-06 Thread Richard Andersen 
Would certainly appreciate understanding where my mistake is in my code 
below.It's rather perplexing because the GUI is doing what I want, but 
something isn't changing within the underlying data structure.

The icon manipulations scripts are really great, except for one.

Adding icons (script 1 here) and deleting icons (script 2 here) are working 
well for me in the UI, but some hidden remnants must still exist (after 
running script 3 here)...


*=== script 1 (I created an @button script) ===*

@language python

''' add 3 icons to a node '''

table = (
'edittrash.png',
'connect_no.png',
'error.png',
)
for icon in table:
fn = g.os_path_finalize_join(g.app.loadDir,
'..', 'Icons', 'Tango', '16x16', 'status', icon)
if g.os_path_exists(fn):
c.editCommands.insertIconFromFile(path=fn)


*=== script 2 (I created an @button script) ===*

@language python

''' remove icons from the node '''

c.editCommands.deleteNodeIcons(p=p)


*=== script 3 ===*

@language python

''' create a listing of all nodes which have icons '''

aList = [p.copy() for p in c.all_unique_positions() if 'lineYOffset' in p.u]
#print('\n'.join([p.h for p in aList]))
g.es_print('\n'.join([p.h for p in aList]))


... because the nodes show up in the list produced by Script 3 and nothing 
I can do (including running the "delete Todo from all" function from within 
todo.py) is removing the data remnant.   I have checked to make sure that 
there are no Tags on the nodes either.

It's a puzzler for me -- probably a no-brainer for many others.

I know this is the canonical answer :-) but would point out that you
can also download
https://github.com/leo-editor/leo-editor/archive/master.zip
as linked here
http://leoeditor.com/download.html (the "Latest" link).

Which gives you the latest code without using git.

​Thanks for pointing this out. Any tool like bzr or git has a learning
curve. Downloading daily snapshots can keep people current without that
cost.

Having said that, if you want to contribute to Leo the only way to do so
directly is to use git.  More importantly, perhaps, git is a truly great
tool. It has so many indirect benefits.  For example, it can tell you what
files have changed, which makes it much less scary to fool around with code.

​I too started with SourceTree.  Alas, it has severe performance problems.
Imo, its best feature is gui-oriented selective adding. You can do
something similar on the command line with git add -p, but I never have.

I finally got fed up with the performance problems (and small fonts, which

​Never mind.  I made several errors.

I changed deleteNodeIcons by adding a p keyword argument so that it could

 Subject: Code academy: icons
   
During our conference call, someone asked whether nodes may have more than one 
icon.  Indeed they can.

For example, running this script will insert three icons. Running the script 
again will insert three more.  You can delete the icons using the 
delete-node-icons command. I'm having trouble deleting icons programmatically.  
I'm investigating.


c.editCommands.setIconList(p, [])c.redraw()
If you don't want to delete them all:icons = c.editCommands.getIconList(p)icons 
= [i for i in icons if ]c.editCommands.setIconList(p, 
icons)

also, add a True param. at end of setIconList call to mark node dirty (changed, 
save required) if desired.
Cheers -Terry


table = (
    'edittrash.png',
    'connect_no.png',
    'error.png',
)
for icon in table:
    fn = g.os_path_finalize_join(g.app.loadDir,
        '..', 'Icons', 'Tango', '16x16', 'status', icon)
    if g.os_path_exists(fn):
        c.editCommands.insertIconFromFile(path=fn)

​Thanks for this.  ​However, I would have thought that calling
c.editCommands.deleteNodeIcons() should work.  Don't see why not, since
delete-node-icons does work.  Any ideas?
