Problems including pyconfig

Hi Jonathan
 I had a look at PyConfig and it made me sad. It's 3 year old code and there are better "included batteries" now. The actual fault is probably related to statements in PyConfig importing data_eval, the outer directory also being called PyConfig and the presence of __init__.py.

 I suppose everyone sooner or later everyone writes a pickle replacement, here is another one, includes a test.

import os
import json

class PyConfig(dict):
    def __init__(self, filename, verbose=1, *args, **kwds):
        self.filename = filename
        self.verbose = verbose

        dict.__init__(self, *args, **kwds)

        if os.path.isfile(self.filename):
            self._read()
        else:
            if self.verbose:
                print "PyConfig info: file '%s' doesn't exist, yet." % (
                    self.filename
                )

    def _read(self):
        if self.verbose:
            print "Reading %r ..." % self.filename

        f = file(self.filename, "r")
        data = json.load(f)
        f.close()

        dict.update(self, data)

    def save(self):
        if self.verbose:
            print "Save into %r ..." % self.filename,

        f = file(self.filename, "w")
        json.dump(self, f, sort_keys=True, indent=4)
        f.close()
        if self.verbose:
            print "OK, data saved."

if __name__ == '__main__':
    py = PyConfig(filename="FooBar.txt")
    py["foo"] = "bar"
    py[1] = "FooBar"
    py.save()

    py = PyConfig(filename="FooBar.txt")
    print py # should look like: {"foo": "bar, 1: "FooBar"}

    # however json silently coerces keys to strings :(
    assert py == {"foo": "bar", '1': "FooBar"}

Thanks a lot! It worked for me but I had to integrate your code in my main and delete the pyconfig folder. Thanks a lot
