using timeit.timeit from pdb with access to a subset of local vars

timeit-from-pdb-hack.md

= Problem =

timeit.timeit() doesn't let you pass local vars to the code to be timed.

= Solution =

(pdb) !import sys, timeit
(Pdb) !dv = (lambda sys=sys: (lambda **kw: setattr(sys.modules['__main__'], 'VARS', kw)))()
(Pdb) !tt = lambda s, sys=sys: sys.stdout.write('%.3g ms\n' % timeit.timeit(s, 'import sys; self = sys.modules["__main__"].SELF', number=10)/10.*1000)

= Example =

(Pdb) dv(self=self, any_other_name=any_other_name)
(Pdb) tt('any_other_name(self.someattribute)')
42.123 ms
