I hit the post button by mistake.
Yesterday got bogged down in fixing bugs. At present, converting
leoGlobals.py from an @file to an @auto tree fails for several reasons:
1. Switching headlines is really complicated: it affects all aspects of unl
handling, and thus all aspects of associating unls with actual positions in
the just-imported outline. More work is like needed. In particular, some
existing organizer nodes are not being linked because the headline in the
@file tree doesn't match the headline in the imported @file tree.
The present code *does* set v._imported_headline for all nodes in the @file
tree before calling vc.update_before_write_at_auto_file to produce the
@auto-view tree. I would have expected that to work for all nodes, but
apparently it doesn't for at least some existing organizer nodes.
2. vc.move_nodes_to_organizers duplicates nodes in some situations. You
would think that doing what the "work list" (vc.global_moved_node_list)
says would be straightforward, but it is turning out to be quite a puzzle.
Fixing this somehow is today's first priority.
3. Both bugs were complicated by an embarrassing blunder: code in two
helpers of vc.create_organizer_data were trying to delete elements of an
list used to iterate a loop. The proper pattern is:
for item in aList[:]: # <-- [:] makes a copy of aList.
<< possibly delete item from aList >>
