mark/unmark-first-parents

[tscv11]

Here are two basic commands I created for researching .leo files. I use them
to mark/unmark the 'breadcrumbs' to nodes when marking/unmarking those nodes
themselves (first parents, counting the way Leo does). I like knowing which
categories and subcategories contain nodes I've marked (the current node is
marked as well, naturally, showing where the breadcrumbs lead).

It's not the code I want to share, really, as much as the idea. My apologies
if this has been covered before. I did a cursory search in LeoRef.py and on
the net before posting this, but it's always possible I've missed something.
I also realize that this may only be useful for my own study habits - I'm
sorry if it doesn't apply to you.

As an afterthought, for those who are wary of .leo files from 'unknown' sources, here's the code:

@language python

def mark_first_parents():
   
    """mark the first parent of each node, moving up the tree
        to the top level. print the list of marked parents."""
   
    parent_lst = []
    p = c.p
    old_p = p
    c.markHeadline(p)
   
    for parent in p.parents():
        if parent:
            c.selectPosition(parent)
            c.markHeadline(parent)
            parent_lst.append(parent.h)
   
    c.redraw()
    if parent_lst:
        g.es("marked: " + str(parent_lst))
       
    c.selectPosition(old_p)
       
mark_first_parents()

@language python

def unmark_first_parents():
   
    """unmark the first parent of each node, moving up the tree
        to the top level. print the list of unmarked parents."""
   
    parent_lst = []
    p = c.p
    c.clearMarked(p)
   
    for parent in p.parents():
        if parent:
            c.selectPosition(parent)
            c.clearMarked(parent)
            parent_lst.append(parent.h)
   
    c.redraw()
    if parent_lst:
        g.es("unmarked: " + str(parent_lst))
       
unmark_first_parents()

​Thanks for this.  The scripts could be copied to leo/scripts/scripts.leo.  In this case, I may create new commands from them.

After consulting Edward and Terry, the finished (I think) 'unmark-first-parents' command now works as intended.

@language python

def unmark_first_parents():
   
    """unmark the first parent of each node, moving up the tree
        to the top level. print the list of unmarked parents."""
   
    parent_lst = []

    old_p = p = c.p

    if p.isMarked():
        c.clearMarked(p)
   
    for nd in p.self_and_siblings():
        if nd.v != old_p.v:
            if nd.v.isMarked():
                break
   
    else:
        for parent in p.parents():
            if parent.isMarked():

​Excellent.  Thanks for this work.  This is on the list of things before Leo 5.7b2.

​I've just created #714 for this, with a milestone of 5.7. This will ensure it remains on my radar for 5.7b2, coming in a day or three.
