Python Configurations

Project description

https://secure.travis-ci.org/pictage/ConfigIt.png?branch=develop

ConfigIt is MIT Licensed Python Configuration library brought to you by the camera shy people at Pictage.

Python is all about the dicts so why do we settle for INIs?

Features

All configuration files are native python files.

Using ConfigIt you can read those files in as a module, or file and return a dictionary with attribute access.

One of the most powerful things about configit is its ability to use other configurations within a configuration.

Installation

To install configit, simply:

$ pip install configit

API Documentation

configit.conf_from_file(filepath)
Reads a string file path and returns a ConfigDict.
filepath = r'tests/configs/default.py'

config = conf_from_file(filepath)
assert config.config_dict.name == 'default'
configit.conf_from_module(module)
Reads an imported module and returns a ConfigDict.
import tests.configs.module_config

config = conf_from_module(tests.configs.module_config)
assert config.config_dict.name == 'module_config'
configit.conf_from_dict(conf_dict)

Reads a dictionary and returns a ConfigDict.

ConfigDicts are accessible by attributes as well as keys.

config = dict(answer=42)

config = configit.conf_from_dict(config)
assert config.answer == 42
configit.use(conf_source)

Within a python configuration you can import another python configuration. The imported configuration will update local name space of the importing configuration. This means values in sub configuration will be accessible in the local configuration.

This can be useful for boiler plate configurations where you only need a few items changed.

file_supplement.py contents:

answer=42

file.py contents:

import configit
configit.use('file_supplement.py')

Code using configit to get the configuration:

import configit
config = conf_from_file('file.py')

assert config.answer == 42

Order matters!

file_supplement.py contents:

answer=42

file.py contents:

import configit
configit.use('file_supplement.py')
answer=5

Code using configit to get the configuration:

import configit
config = conf_from_file('file.py')

assert config.answer == 5

For further examples refer to included tests.
