Yes, it is possible to do a prototype in a few hours, with a doctor's
appointment in between.
Rev 2874a6f adds a copy of @button checker to leoCheck.py. I did this
mostly so I wouldn't have to show the entire code here.
The guts of the prototype is this method:
patterns = (
('class', re.compile(r'class\s+[a-z_A-Z][a-z_A-Z0-9]*.*:')),
('def', re.compile(r'^\s*def\s+[\w0-9]+.*:')),
('c.x=', re.compile(r'^\s*c\.[\w.]+\s*=')),
# Assignment to c.
('call', re.compile(r'^\s*(\w+)(\.\w+)*\s*\(.*\)')),
# Possible function call.
)
ignore = ('dict', 'enumerate', 'list', 'tuple')
# Things that look like function calls.
def show(self, fn, node):
s = leoAst.AstFormatter().format(node)
aList = g.splitLines(s)
g.trace('%s lines, %s' % (len(aList), g.shortFileName(fn)))
for s in aList:
# Match each pattern separately for better control.
for kind, pattern in self.patterns:
m = pattern.match(s)
if m:
try:
call = m.group(1)
if not any([call.startswith(z) for z in self.ignore]):
print('%6s %s' % (kind, s.rstrip()))
except IndexError:
# No m.group(1)
print('%6s %s' % (kind, s.rstrip()))
And here is the results, when node is the ast tree for nodetags.py:

Imo, the cool thing about this is tat the regex's detect what we want to
detect.
