# cfgsaver

Python library to save and fetch configuration data in a standard/conventional path and format.

# Installation

```bash
pip install cfgsaver
```

# Usage

Import the `cfgsaver` module to save/read configuration values in your source files:

```python
from cfgsaver import cfgsaver

def save_config():
	# saves configuration data to ~/.config/<your_package>/cfg.json
	# unless cfgpath parameter is overridden:
	config = {'name': 'Prahlad', 
	'language': 'Python', 
	'framework': 'Flask'
	}
	cfgsaver.save('<your_package>', config)

def get_config():
	# gets configuration data from ~/.config/<your_package>/cfg.json 
	# unless cfgpath parameter is overridden:
	config = cfgsaver.get("<your_package>") #returns None if config file doesn't exist
```


In case you want to ship some default configuration data packaged with your app, then read the below instructions carefully:

Ensure to include the path to your cfg.json in `MANIFEST.in` as follows (you'll have to copy this file from ~/.config/<your_package> to your source directory for packaging purpose):

```bash
include <your_package>/cfg.json
```
		
Override the PostInstall class in your setup.py like this in order to save your config file to the user's machine after installation:

```python
from setuptools import setup, find_packages
from setuptools.command.install import install
import shutil

class PostInstallCommand(install):
	"""Post-installation for installation mode."""
	def run(self):
		install.run(self)
		fpath = os.path.join(self.install_lib, your_package)
		fpath = os.path.join(fpath, "cfg.json")
		tpath = os.path.join(os.path.expanduser("~"), ".config/<your_package>/cfg.json")
		if not os.path.isdir(tpath):
			os.makedirs(tpath)
		shutil.move(fpath, tpath)

s = setup(
	name = "your_package",
	packages=find_packages(),
	..
	..
	..
	cmdclass={
		'install': PostInstallCommand,
	},
)
```
