Starting¶
Rickle 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 rickled
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 rickled import Rickle
>> config = Rickle('./config.yaml', deep=True, load_lambda=True)
>> config.BASIC.dictionary
{'one' : 1, 'two' : 2}
>> config.BASIC.callable_lambda()
hell world!
