FWIW I might have a use for this as a cheap way of printing out 'scratch'
nodes/subnodes, with indentation. I make things like shopping lists this
way. Having a default scratch HTML file might be a nicer way to do this,
for me at least.
Here's a quick-and-dirty script to display a subtree in the browser as an
indented list. It leaves an .html file in the ~/.leo directory. It's not
fancy but it does the job.
@language python
"""Display current subtree in web browser.
Writes a temporary .html file in ~/.leo.
"""
import os.path
import webbrowser
from tempfile import NamedTemporaryFile
TEMPDIR = os.path.expanduser(r'~/.leo')
ENCODING = 'utf-8'
def subtree_to_indented_list(event = None):
"""Output to browser an indented list for a subtree."""
tree = c.p.self_and_subtree()
indented = ''
for x in tree:
indent = ' ' * (x.level() - 1)
body_lines = x.b.split('\n')
body_lines_indented = [indent + l for l in body_lines]
body = '\n'.join(body_lines_indented)
indented += indent + x.h + '\n' + body + '\n'
return indented
indented = subtree_to_indented_list()
if indented:
html = f'<pre>{indented}</pre>'
with NamedTemporaryFile(suffix = '.html',
dir = TEMPDIR, delete = False) as f:
f.write(html.encode(ENCODING))
webbrowser.open(f.name)
else:
g.es('No results')
I also have a version that will open a print dialog and print on a printer,
if you would like that.
