Usage

DictRemapper

This class can remap a dictionary if a keymap is passed as argument.

import redict

keymap = {
    'message': 'm',
    'user': 'u',
    'permissions': 'p',
    'role': 'r',
}

data = {
    'message': 'hello world',
    'user': 1,
    'permissions': [
        {'role': 1, },
        {'role': 2, },
        {'role': 3, },
    ]
}

remapped = redict.DictRemapper(data, keymap=keymap)()

Results in:

{
    'm': 'hello world',
    'u': 1,
    'p': [
        {'r': 1, },
        {'r': 2, },
        {'r': 3, },
    ]
}

Note

Currently using integers as dict keys are not supported.

JsonRemapper

This class can remap a json string if a keymap is passed as argument. In case you’re working with big json files, it can help to reduce the size of your json files.

import redict

keymap = {
    'message': 'm',
    'user': 'u',
    'permissions': 'p',
    'role': 'r',
}

json_string = (
    '{'message': 'hello world', 'user': 1, '
    'permissions': [{'role': 1, }, {'role': 2, }, {'role': 3, }]}'
)

remapped = redict.JsonRemapper(json_string, keymap=keymap)()

Results in:

'{'m': 'hello world', 'u': 1, 'p': [{'r': 1, }, {'r': 2, }, {'r': 3, },]}'

You can also minify the result:

remapped = redict.JsonRemapper(json_string, keymap=keymap, minify=True)()

'{'m':'helloworld','u':1,'p':[{'r':1,},{'r':2,},{'r':3,},]}'
