There's a compact traceback printer in asyncore (compact_traceback). I used
it as the basis for a compact stack printer:
import os
import sys
# adapted from asyncore.compact_traceback()
def compact_stack(start=0, size=100):
"""build a compact stack trace from frame start to end"""
f = sys._getframe(start+1) # don't include this frame
info = []
while f:
fn = os.path.normpath(os.path.abspath(f.f_code.co_filename))
info.append((fn, f.f_code.co_name, f.f_lineno))
f = f.f_back
# eliminate any common prefix the filenames share
info = [(f.split(os.sep)[-1], c, l) for (f, c, l) in info]
return '\n'.join(['[%s|%s|%d]' % x for x in info[:size]])
def print_compact_stack(f=sys.stderr, start=0, size=100):
print >> f, compact_stack(start+1, size)
