Installation
============

For stable version 
   - pip install trace-dkey

For development 
   - git clone https://github.com/Agent-Hellboy/trace-dkey
   - cd trace-dkey 
   - python -m venv .venv 
   - source .venv/bin/activate

Example
=======


you can use the library as ``python3 -m trace_dkey --file=test.json --key=name``, test.json is 

A JSON file containing name as key

.. code:: py

   >>> from trace_dkey import trace
   >>> l={'a':{'b':{'c':{'d':{'e':{'f':1}}}}}}
   >>> print(trace(l,'f'))
   [['a', 'b', 'c', 'd', 'e', 'f']]

   Now you can query it as l['a']['b']['c']['d']['e']['f']

   >>> l['a']['b']['c']['d']['e']['f']
   1

Documentation
=============

For more details, you can refer to the `documentation <https://agent-hellboy.github.io/trace-dkey/>`_.

General Info
============

- The value returned by the `trace` function is an array of paths, where each path is an array of dictionary keys.
- Because of that, the library can be used in a practical way by taking advantage of this format.
- In the example below we use the returned path to iterate over the dictionary keys and print the key value:
  
.. code:: py
 
    from trace_dkey import trace
    l={'a':{'b':{'c':{'d':{'e':{'f':1}}}}}}
 
    paths = trace(l,'f')

    for path in paths:
       dic = l
       for key in path:
          dic = dic[key]
       print(dic)

| Someone made a nice comparision of this lib(trace-dkey) with one of the famous lib(yamlpath) which is doing the similar thing
