JSON and basic sage types

asked 2013-07-02 13:17:27 -0600

Is there any package that produces a JSON string from sage dictionary containing "basic" sage types ?

Something like [1]:

class jsonmegua(json.JSONEncoder):

def default(self, o):
    try:
        if type(o)==sage.rings.integer.Integer:
            json_obj = int(o)
        elif type(o)==sage.rings.real_mpfr.RealLiteral:
            json_obj = float(o)
        elif type(o)==sage.rings.real_mpfr.RealNumber:
            json_obj = float(o)
        elif type(o)==sage.symbolic.expression.Expression:
            json_obj = latex(o)
        else:
            json_obj = o
    except TypeError:
        pass
    else:
        return json_obj

    # Let the base class default method raise the TypeError
    return JSONEncoder.default(self, o)

Do you want the internal representation of your object, a sage command that recreates the object, or a human-readable representation? Depending on your needs you'd want very different JSON objects, so there is no one-size-fits-all solution to your question. Essentially you'll have to write your own depending on your needs.

The habit of the search for standards made ask the question. Thank you.
