Project description

An app configuration toolkit that tries to do things right.

Install

Convoke is available from PyPI:

pip install convoke

Usage

Create a Settings object:

from convoke import Settings

settings = Settings('My App Name')

Convoke will pull settings from three places, in order of priority:

  1. Local overrides:

    Settings('My App Name', foo='bar')
  2. os.environ values (upper-cased):

    settings.get('foo') == os.environ.get('FOO')
  3. a provided INI-style configuration filepath or config.ini in the OS-specific application directory:

    # ~/.config/config.ini (or OS equivalent)
    foo = bar

The Settings object provides convenience accessors for different value types:

  • Strings:

    settings['foo']
    settings.get('foo', default='blah')
  • Boolean:

    settings.as_bool('foo', default='True')
  • Integer:

    settings.as_int('foo', default='5')
  • Float:

    settings.as_float('foo', default='5.0')
  • Path (returns path.Path objects):

    settings.as_path('foo', default='~/blah')

For simple usage, there’s also a singleton Settings mode:

settings = convoke.get_settings('My App Name', foo='bar')
assert settings.app_name == 'My App Name'
assert settings['foo'] == 'bar'

# Further calls to get_settings returns the same object:
settings2 = convoke.get_settings()
assert settings2 is settings

# Future overrides have no effect:
settings2 = convoke.get_settings('Some other name', foo='blah')
assert settings.app_name == 'My App Name'
assert settings['foo'] == 'bar'
