Because I have two nodes which were originally identical but are now
different and I want to see the differences.
My outline loads a @file called ~/.leo/t/gen which contains a @button
with several @rclick children for commonly used tasks. So I add a new
one, @rclick diff
selected = c.getSelectedPositions()
open('/tmp/a_diff', 'w').write(selected[0].b)
open('/tmp/b_diff', 'w').write(selected[1].b)
import os
os.system("xxdiff /tmp/a_diff /tmp/b_diff &")
which is horrible for a number of reasons but also took only moments
to write. And now, not only does this Leo session have a visual node
diff capability, but also every future session which loads ~/.leo/t/gen.
When you can go from wanting to having a feature in less time than it
takes to write an email about it - well, that's "why Leo".
(I also have @file ~/.leo/sql and @file ~/.leo/dml for commands for
handling SQL and an XML dialect I use a lot, it's a great way to manage
little snippet functions)
Cheers -Terry
