Regarding tags, I hacked the nodetags.py plugin together, available at
commit b9a764c59de263fbdb47969f1d318759b955c442.
Attached is a test leo file for playing with it.
This is only an API for tags, but I feel like it should simplify the
process and allow someone to focus on the important bits, i.e. UI hooks,
rather than low-level details. Also, it's usable now for scripts.
Here is the docstring:
Leo.plugins.nodetags
Provides an API for manipulating and querying textual tags on nodes
By Jacob M. Peck
This plugin registers a controller object to c.theTagController, which
provides the following API:
tc = c.theTagController
tc.get_all_tags() # return a list of all tags used in the current
outline, automatically updated to be consistent
tc.get_tagged_nodes('foo') # return a list of positions tagged 'foo'
tc.get_tags(p) # return a list of tags applied to the node at position
p; returns [] if node has no tags
tc.add_tag(p, 'bar') # add the tag 'bar' to the node at position p
tc.remove_tag(p, 'baz') # remove the tag 'baz' from p if it is in the
tag list
Internally, tags are stored in p.v.unknownAttributes['__node_tags'] as a
set.
