What is it?

• A stringifier and formatter for SimpleNamespace which attempts to make the data as readable as possible.

Why create it?

• I use SimpleNamespace often to hold state and needed a way to print it out for debugging purposes.

Simple usage

from pretty_simple_namespace import pprint
from types import SimpleNamespace as o

joe = o(
    name={"first": "joe", "last": "schmo"},
    age=30,
    favoriteFoods=["apples", "steak"],
)

pprint(joe)
# prints
# {
#   name: {
#     first: 'joe'
#     last: 'schmo'
#   }
#   age: 30
#   favoriteFoods: [
#     'apples'
#     'steak'
#   ]
# }

Features

• handles recursive structures by tracking and printing references nicely
• recurses into types list, dict and SimpleNamespace for now
• has special-case printing for types bool, str, callable and None
  • booleans and None are printed lowercase
  • strings are wrapped in single quotes
  • callable appends () e.g. myMethod(). Arguments aren't represented
• all other types are printed by wrapping it in str e.g. str(userDefinedType)

Limitations

• multi-line strings look ugly
• doesn't have a way to recurse into structures other than what's listed above

Api

format(something, indent=2) => str

• formats something to a string as seen in Simple usage

pprint(something, indent=2) => None

• just prints the formated something

wrapWith(*, indent) => Wrapped module

• use this when you want to call format or pprint with a different default indent value so you don't have to pass it manually all the time.

  e.g.

  from pretty_simple_namespace import wrapWith
  
  pprint = wrapWith(indent=4).pprint
  pprint(o(tabbed4spaces=True))
  # {
  #     tabbed4spaces: true
  # }

Wrapped module

• just an instance of SimpleNamespace with two attributes format and pprint.
