pyspry 1.0.2

A Springy Little Configuration Reader











Influenced by Spring Boot's YAML configuration features,
this library reads system configuration settings from environment variables and YAML files.
Installation
To install using pip:
pip install pyspry

Usage
By default, a file named config.yml in the current directory will be loaded and parsed for
configuration settings. These can be accessed through the pyspry.settings module.
For example, consider the following config.yml file:


DATABASES:
default:
AUTOCOMMIT: true
NAME: db.sqlite3
DEBUG: true
DEFAULT_CHARSET: utf-8


These configuration settings can be accessed as follows:
>>> from pyspry import settings
>>> settings.DEBUG
True

>>> settings.DEFAULT_CHARSET
'utf-8'

Specifying Alternate Config Files
Set the environment variable PYSPRY_CONFIG_PATH to override the default path to the configuration
file:
>>> import os; os.environ["PYSPRY_CONFIG_PATH"]
'sample-config.yml'

>>> from pyspry import settings
>>> settings.PYSPRY_STATICFILES_FINDERS
['django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder']

Variable Prefixes
Set the environment variable PYSPRY_VAR_PREFIX to filter which settings are loaded:
>>> import os; os.environ["PYSPRY_VAR_PREFIX"]
'PYSPRY'

>>> from pyspry import settings
>>> "TEST_RUNNER" in settings # the prefix is automatically inserted
True

>>> "IGNORED_SETTING" in settings # see the last line in 'sample-config.yml'
False

Nested Structures
If the configuration includes nested data structures, each layer of nesting can be traversed using
_-separated names:
>>> settings.LOGGING["version"] == settings.LOGGING_version == 1
True

>>> settings.LOGGING["loggers"]["pyspry"]["level"] == \
... settings.LOGGING_loggers_pyspry_level == 'DEBUG'
True

Environment Variables
In many cases, it can be useful to set one-off overrides for a setting. This can be done with an
environment variable:
>>> import importlib, os
>>> settings.LOGGING_loggers_pyspry_level
'DEBUG'
>>> os.environ["PYSPRY_LOGGING_loggers_pyspry_level"] = "INFO"
>>> settings = importlib.reload(settings)
>>> settings.LOGGING["loggers"]["pyspry"]["level"]
'INFO'

Django Integration
This package was originally designed for use with the Django
framework. To use it:
# after installing the package, specify it as the settings module
export DJANGO_SETTINGS_MODULE=pyspry.settings

django-admin diffsettings
