Pickle Rick

Starting

Pickle Rick is a lightweight tool for loading and writing very small Python objects to YAML or JSON representations. This is especially useful for creating YAML config files and serialising them as Python objects. Works great in interactive Python environments like notebooks.

To install:

pip install pickle-rick

Create a YAML file, call it “config.yaml”:

BASIC:
 text: test
 dictionary:
   one: 1
   two: 2
 number: 2
 list:
   - one
   - two
   - four
   - name: John
     age: 20
 USERNAME:
   type: env
   load: USERNAME
 callable_lambda:
   type: lambda
   load: "lambda: print('hell world!')"
 datenow:
   type: lambda
   import:
     - "from datetime import datetime as dd"
   load: "lambda: print(dd.utcnow().strftime('%Y-%m-%d'))"
 test_function:
   type: function
   name: test_function
   args:
     x: 7
     y: null
     s: hello world
     any:
       - 1
       - hello
   import:
     - "math"
   load: >
     def test(x, y, s, any):
       print(math.e)
       iii = 111
       print(iii)
       print(x,s)
       if y:
         print(type(y))
       else:
         print(y)
       for i in any:
         print(i)

Then import the tools:

>> from pickle_rick import PickleRick

>> config = PickleRick('./config.yaml', deep=True, load_lambda=True)

>> config.BASIC.dictionary
{'one' : 1, 'two' : 2}

>> config.BASIC.callable_lambda()
hell world!

About

Pickle Rick is quick to use tool mainly meant to easily encapsulate config YAML files in other Zipfian Science tools.
