fulljson 0.0.53

simple json conversion implements using stack structure and recursive method

FullJSON

The package is for JSON conversion in Python enviroment.

JSON Type	JSON Type Example	Python Type	Python Type Value
object	{}	dict	type({})
array	[]	list	type([])
string	"example"	str	type('example')
number	1/1.0	int/float	type(1)/type(1.0)
"true"	true	True	type(True)
"false"	false	False	type(False)
"null"	null	None	type(None)

Implements

Convert a JSON string into a JSON object

JSON.parse(value) is based on stack structure. There are three stacks in the program, stack stack for characters, class_stack stack for list and dict, keyvalue_stack stack for name/value pair. Scan each character in the string, do the following:

1. If is [, put type/value into class_stack stack
2. If is {, put type/value into the class_stack stack, and put an empty key/value pair (named border) into the keyvalue_stack stack
3. If is,, according to class_stack stack top type (list and dict), list is to operate on the top of the class_stack stack and call its append method, dict is pushed into the keyvalue_stack stack
4. If is ], popping all the elements on the top of the stack stack until it encounters [
5. If is }, pop the keyvalue_stack stack and pop all the elements on the top of the stack until it encounters border
6. If is :, operate on the top of the keyvalue_stack stack and modify the value in the key/value pair
7. Other, put characters into the stack stack

Convert JSON values to JSON strings

JSON.stringify(value) is using recursive method.

1. If it is a basic type in Python (number, string, bool, None), return the corresponding string (1/1.0, "example", true/false, null)
2. If it is list and dict, repeat step 1 for each element in the list and dict
3. Others, It is a class, consider as a dict type, terating over member variables of a class, do the same action as step 1

Installation

pip install fulljson 

Examples

• Convert a JSON string into a JSON object.

>>> from fulljson import JSON
>>>
>>> value = '["foo", {"bar": ["baz", null, 1.0, 2, true]}]'
>>> print(JSON.parse(value))
['foo', {'bar': ['baz', None, 1.0, 2, True]}]
>>>

• Convert JSON values to JSON strings.

>>> from fulljson import JSON
>>>
>>> value = ["foo", {"bar": ["baz", None, 1.0, 2, True]}]
>>> print(JSON.stringify(value))
["foo",{"bar":["baz",null,1.0,2,true]}]
>>>

• Format JSON object or JSON strings

>>> from fulljson import JSON
>>>
>>> value = [{'foo': 'new 0', 'index': None}, "sat", {'bar': 'new 2', 'index': [1, True]}]
>>> print(JSON.format(value))
[
    {
        "foo":"new 0",
        "index":null
    },
    "sat",
    {
        "bar":"new 2",
        "index":[
            1,
            true
        ]
    }
]
