a JSON encoder that allow use set a "depth" attribute in order to fine tune the output JSON string.
This encoder is compatible with the default python json module.
The depth attribute only works when the indent attribute is set to a non-zero value.
##Example##
>>> import json
>>> from pp_json_encoder import PPJSONEncoder
>>> data_structure = {
... 'layer1': {
... 'layer2': {
... 'layer3_1': [{"x":1,"y":7}, {"x": 0, "y": 4}, {"x": 5, "y": 3}, {"x":6,"y":9}],
... 'layer3_2': 'string'
... }
... }
... }
>>> print json.dumps(data_structure, indent=2, cls=PPJSONEncoder, depth=2)
{
"layer1": {
"layer2": {"layer3_2": "string", "layer3_1": [{"y": 7, "x": 1}, {"y": 4, "x": 0}, {"y": 3, "x": 5}, {"y": 9, "x": 6}]}
}
}
>>> print json.dumps(data_structure, indent=2, cls=PPJSONEncoder, depth=3)
{
"layer1": {
"layer2": {
"layer3_2": "string",
"layer3_1": [{"y": 7, "x": 1}, {"y": 4, "x": 0}, {"y": 3, "x": 5}, {"y": 9, "x": 6}]
}
}
}
>>> print json.dumps(data_structure, indent=2, cls=PPJSONEncoder, depth=4)
{
"layer1": {
"layer2": {
"layer3_2": "string",
"layer3_1": [
{"y": 7, "x": 1},
{"y": 4, "x": 0},
{"y": 3, "x": 5},
{"y": 9, "x": 6}
]
}
}
}
>>> print json.dumps(data_structure, indent=2, cls=PPJSONEncoder, depth=5)
{
"layer1": {
"layer2": {
"layer3_2": "string",
"layer3_1": [
{
"y": 7,
"x": 1
},
{
"y": 4,
"x": 0
},
{
"y": 3,
"x": 5
},
{
"y": 9,
