Simple and flexible separation settings from code

Install: pip install flexiconf

How to use:

Config creation:

import flexiconf
config = flexiconf.Configuration([ ...loaders... ])

Configuration is being read at the moment of an object creation, all get are fast and read-only operations. Sources of the configuration are defined by loaders list, that will be described later.

You may also create multiple configurations with different sources - for example, parse command line parameters first, to define configuration files to be read as a full config later.

Accessing parameters:

Configuration is treated as a tree of dicts and lists. For best compatibility, recommended to use only alphanumeric symbols and _ as a key. Point . inside the key is treated as a divider between nested sections during both parsing ang getting.

After being parsed, tree could be received directly by Configuration.as_dict() method.

Different parameters could be received via get operators: with auto cast (config.get_bool(...), config.get_int(...), etc) or by generic get method. get methods receive key_path parameter (e.g. section_1.subsection.key_name) and optional default parameter of any type, including None. KeyError will be raised, if key was not found and default option was not provided.

Loaders:

Loaders are objects, that read configuration from different sources. Loaders are executed in direct order, later loaders will override previously parsed options with the same keys.

JsonLoader and IniLoader are both take optional config_files_pattern parameter, describing glob pattern to files with configuration. If not provided, parser will look for all *.json/*.ini files in the caller directory recursively.

EnvLoader takes optional pattern parameter, to define keys to be added in configuration.

ArgsLoader looks for all command line parameters with key=value format, with optional number of - as a prefix.

Custom loaders:

If you want to write your own loader, you could simply inherit from flexiconf.BaseLoader class and implement load method.
