Bad paste, sorry for the noise. Corrected version:
def production(s):
# create the function that the decorator returns
# which gets immediately called with the function
# containing the actual evalling/AST-generating code
def impl(f):
# p_impl is the parser function that just calls to the decorated
# function
def p_impl(p):
return f(p)
p_impl.__doc__ = s
# up in the namespace containing the decorator, assign our
# p_impl function to a generated name where ply will find it.
# It checks that name __name__ attribute of the function
# starts with p_... we need to set that.
fnname = 'p_' + s.replace(':','').replace(' ', '_')
p_impl.__name__ = fnname
frameup = sys._getframe(1)
frameup.f_locals[fnname] = p_impl
return impl
