derpconf

Build Status

derpconf abstracts loading configuration files for your app. derpconf was extracted from thumbor.

Intalling

Installing derpconf is as easy as:

pip install derpconf

Usage

Using it is as simple as:

from derpconf.config import Config

conf = Config.load('/path/to/my/cfg.conf')

assert conf.MY_KEY == 'MY_VALUE' # assuming there's a key called MY_KEY in
                                 # the configuration file.

Settings Defaults

If you want to set default values for your configurations, just call:

Config.define('MY-KEY', 'DEFAULT VALUE', 'Description for my key', 'Section')

The values that define gets are:

  • the configuration key;
  • the default value for that key if it's not found in the configuration file;
  • the description for this key. This is very useful for generating configuration file examples.
  • the section that this key belongs to. Again very useful for generating configuration file examples.

Generating Configuration Examples

To generate a configuration example, you just need to call the get_config_text method. Let's see an example:

from derpconf.config import Config

Config.define('foo', 'fooval', 'Foo is always a foo', 'FooValues')
Config.define('bar', 'barval', 'Bar is not always a bar', 'BarValues')
Config.define('baz', 'bazval', 'Baz is never a bar', 'BarValues')

config_sample = Config.get_config_text()
print config_sample # or instead of both, just call generate_config()

The following text will be print into the standard output:

################################## FooValues ###################################

## Foo is always a foo
## Defaults to: fooval
#foo = 'fooval'

################################################################################


################################## BarValues ###################################

## Bar is not always a bar
## Defaults to: barval
#bar = 'barval'

## Baz is never a bar
## Defaults to: bazval
#baz = 'bazval'

################################################################################

A good sample of using derpconf can be seen at thumbor's configuration file.
