some ideas about offline pre-computation of functions in python

offliner.py

import inspect

REGISTRY = []
CACHE = {}

def offline_runner():
    for fn, kwargs in REGISTRY:
        #print "OFFLINE", fn, kwargs
        CACHE[(fn, str(kwargs))] = fn(**kwargs)


def offline(**kwargs):
    def real_offline(fn):
        fnargs = inspect.getargspec(fn)
        REGISTRY.append((fn, kwargs))
        def wrapped(*inner_args):
            initial_env = dict(zip(fnargs.args, inner_args))
            #print "GETTING ", fn, initial_env
            return CACHE.get((fn, str(initial_env)), None)
        return wrapped
    return real_offline

@offline()
def test():
    return 1 + 1

@offline(a=5)
def test2(a):
    return a * 5

#@offline(a__list=range(5))
#def test3(a):
#    return a * 5

print test()
print test2(5)
offline_runner()
print test()
print test2(5)
