configer 1.2

Easy configuration of arguments in a python code!

Configer

This is the repository for the package CONFIGER helps with easy configuration of arguments in a python code.

Introduction

When Python programs grow large, one would eventually need a way to load configurations through a file. The common answer to this would by Python's ConfigParser. But at least I find the result of using ConfigParse an ugly code:

import ConfigParser
Config = ConfigParser.ConfigParser()
Config.read("c:\\tomorrow.ini")
Config.get(section, option)

That's why I packaged my solution to this issue. Configer basically gives you a flattened ConfigParser with extra functionality:

• dot-access of values in the settings file
• dump settings to a file for later use
• add different settings while choosing to overload previous one.

Dependencies

This package is written for Python 2.7. The only dependency is configparser and will be installed automatically by the setup.py.

Installation

In the root directory, type in

pip install .

Examples

Overall Configer will be a sleek way to disentangle settings away from the mechanics. An exact copy of the above code will be:

from configer import Configer
Config = Configer(default_ps_fname='c:\\tomorrow.ini')
Config.option

Note that you don't have sections anymore and you can access an option with a dot-access approach.

Other use cases would be:

1. Loading default settings

   default_ps_fname = 'pyconfiger/Configer/test/sample_settings.ini'
   ps = Configer(default_ps_fname=default_ps_fname)
   print(ps.status) # None
   

2. Loading default settings while adding new arguments

   ps = Configer(default_ps_fname=default_ps_fname, status=False)
   print(ps.status) # False
   ps.status = True
   print(ps.status) # True
   ps.new_status = True
   print(ps.new_status) # True
   

3. Loading default settings while initializing with a dictionary of arguments

   ps = Configer(default_ps_fname=default_ps_fname, status=False,**{'somethings': [1.0, 2.0]})
   print(ps.somethings) # [1.0, 2.0]
   

4. Adding and overloading with a second Configer instance

   ps1 = Configer(status=False)
   ps2 = Configer(status=True, othersetting = 'this')
   
   ps3 = ps1 + ps2
   print(ps3.status) # False
   print(ps3.othersetting) # 'this'
   
   ps4 = ps1.overload(ps2)
   print(ps4.status) # True
   

5. Dumping current Configer instance as an .ini file

   ps = Configer(default_ps_fname=default_ps_fname, status=False)
   print(ps.status) # False
   ps.dump_settings(fname='~/settings.ini') # saves the settings to the specified file
   

Tests

To run the tests, type in in the root directory:

python -m unittest discover
