Simple extended version of JSON encoder for handling serialization of few other than standard python data types. It tries to use simplejson lib if found then fallback to stdlib json module. Raises an exception if no json module can be loaded.
Supports the following objects and types by default:
| Python | JSON |
|---|---|
| dict, namedtuple | object |
| list, tuple, set | array |
| str, unicode | string |
| int, long, float | number |
| True | true |
| False | false |
| None | null |
| Decimal | str |
| complex | array[real,img] |
| datetime.date | date.isoformat ECMA-262 |
| datetime.datetime | datetime.isoformat ECMA-262 |
| decimal.Decimal | string of decimal |
| datetime.time | datetime.tim.isoformat |
In addition if object have __json__ attribute or method encoder will use that for serialization
usage:
from ext_json import json
imported json have already extended encoder as default so no special calls are needed to execute json.dump or json.dumps
if you prefer to import specific encoder you can do:
from ext_json import simplejson # for simplejson <-- can be None from ext_json import stdlibjson # for json from stdlib
