pytb.config module

Configure the Toolkit

Some modules use a configuration based on a config-file hierarchy. This hierarchy starts in the current working directory moving to parent folders until the root of the filesystem is reached.

The hierarchy is then traversed in reverse order and in each folder, a file named .pytb.conf is loaded if available. The API docs for the module reference when a configuration is used. The function of the config parameters is documented in the Default Config

Default Config

The pytb package provides a config file with sane default values that should work in most cases. The file is loaded as first file overwriting the hard-coded defaults in the pytb.config.Config class but being overwritten by any more-specific config file in the lookup hierarchy.

API Documentation

This module handles the .pytb.conf files

class pytb.config.Config(verbose: Optional[bool] = False)

Bases: configparser.ConfigParser

Provides functionality to load a hierarchy of .pytb.config files.

Parameters:verbose – output debugging information including the paths that will be checked for config files as well as all files that are actually parsed

config_file_name = '.pytb.conf'

filename of config files

default_config_file = PosixPath('/home/docs/checkouts/readthedocs.org/user_builds/py-toolbox/envs/latest/lib/python3.7/site-packages/py_toolbox-0.7.0-py3.7.egg/.pytb.conf')

The loaction of the default config file (in the root of the package)

static get_config_file_locations() → Sequence[pathlib.Path]

Get a list of possible configuration file paths by starting at the current working directory and add all parent paths until the root directory is reached

The default config file location is always the first path in the list. More specific configuration files should appear later in the list (from unspecific to more specific)

getlist(*args, **kwargs) → Sequence[str]

get a list of values that are seperated by a newline character

>>> config = Config()
>>> config.read_string("""
...     [test]
...     list=a
...         b
...         c
...     """)
>>> config.getlist('test', 'list')
['a', 'b', 'c']

reload() → None

load the configuration by initialising the default values from Config._defaults and then traversing all possible configuration files overwriting all newly found values

pytb.config.current_config = <pytb.config.Config object>

An instance of config that is automatically initialized when importing the module
