I'm not a big fan of counts of lines of code, but sometimes it's fun or
otherwise useful. I didn't see a script to count the LOC in scripts.leo or
PyLeoRef.leo, so I came up with one, but I wondered whether anyone else has
a slicker one.
My script counts lines of code in a Leo subtree, not in external files.
The subtree could be a file, but doesn't need to be.
Of course, there's the question of what counts as a line of code. Part of
that is whether a docstring counts. If it does, the code is way easier
since you don't have to figure out where a docstring begins or ends.
My version counts all non-blank, non-comment, non-directive lines. So it
omits Python decorators, but there are unlikely to be enough of them to
really matter. Here's my script:
"""Count non-blank, non-comment, non-directive lines in subtree."""
p = c.p
nodes = p.self_and_subtree()
cnt = 0
for n in nodes:
lines = [l for l in n.b.split('\n') if l.strip()]
lines = [l for l in lines if not l.lstrip()[0] in ('#', '@')]
cnt += len(lines)
g.es(cnt, f'lines of code in "{p.h}"')
This executes pretty fast even on a large outline like PyLeoRef, which for
the *Code* subtree outputs
154966 lines of code in "Code"
