Simple Config Manager

Simple Config Manager is a very simple Python pure in-app config manager. It will centralize all your app settings in a unique class which will hold a key-value setting.

Features

• Allow namespace-like definitions
• Keys can be set and accessed as attributes or dictionary key values
• Allows strict type-checking of values

Usage

Let's suppose we want to store settings for our project. We decided to store those settings in 3 areas , namely main, backend, frontend,

A simple pattern usage could be:

config = ConfigManager()

# create namespaces
config('main')
config('frontend')
config('backend')

Now we can operate with main, backend, frontend as if they were attributes:

# Sets parameters for main area
config.main.config_file = 'config.json'  #  config file
config.main.global_log_file = '/var/log/my_app.log'  #  a log file

# Sets parameters for frontend area
config.frontend.index_file = 'index.html'

# Sets parameters for backend area
config.backend.main_file = 'main.py'

We can read or update those values as normal properties:

print('Config file is', config.main.config_file)
config.main.config_file = new_config_file  # Update property

Defining nested namespaces

It's pretty straightforward. You can do it either with:

config('main.subsection')

or with

config('main')('subsection')

Accessing properties as dict keys

All the above is true also for dict-like accesses. Just replace parenthesis with square brackets:

config['main.subsection.value'] = 1

or

config['main']['subsection']['value'] = 1

which is equivalent.

You can even mix modes!

config['main.subsection'].value = 1
print(config['main.subsection.value'])  # 1

To do

• Allow defining read only properties
