ConfigMaster 2.2.0

Programmatic configuration library for Python 3.

ConfigMaster

What is ConfigMaster?

ConfigMaster is a simple library for accessing config files programmatically. No longer will you have to mess with list lookups and dict lookups when you wish to load a config file.

Instead, objects in the file are accessed as simple class attributes.

What is supported

ConfigMaster supports the following formats built-in:

• YAML Config Files (through the PyYAML module)

• JSON Config Files (through json)

• INI Config Files (through ConfigParser)

• Networked versions of YAML/JSON files.

Support for different types of config files grows all the time - feel free to fork and add support!

TODO

• [STRIKEOUT:Add in support for python ConfigParser formats] Added in version 1.4.0

• [STRIKEOUT:Add in networked JSON support] Added in version 1.3.0

• Add more docstrings

• Make proper documentation

• [STRIKEOUT:Add tests] Added in version 1.3.1

How to install

For the latest stable version uploaded to PyPI, use:

pip install configmaster

For the latest stable version uploaded to bitbucket, use:

pip install git+https://github.com/SunDwarf/configmaster

For the latest dev version, use:

pip install git+https://github.com/SunDwarf/configmaster@dev

After installing, running the tests is recommended.

py.test -rfEsxXw -v --strict test.py

How to use

ConfigMaster handles everything for you. Simply specify the location of your file, and the values will be automatically loaded for you.

>>> from configmaster import YAMLConfigFile
>>> cfg = YAMLConfigFile.YAMLConfigFile("test.yml") # Created automatically if it doesn't exist

Networked config files are supported too.

>>> from configmaster import JSONConfigFile
>>> cfg = JSONConfigFile.NetworkedJSONConfigFile("http://example.com/data.json")

To access config values, get the attribute you want from the config object stored.

# YAML data is {"a": 1, "b": [1, 2], "c": {"d": 3}}
>>> cfg.config.a
1
>>> cfg.config.b[1]
2
>>> cfg.config.c.d
3

To populate your config data, just pass a dict to initial_populate. If the file is empty, this gives it default values, and returns True. If it isn’t, nothing happens. Note: This will fail with an exc.NetworkedFileException on networked files!

>>> pop = cfg.initial_populate({"a": 1, "b": [1, 2], "c": {"d": 3})
>>> if pop: cfg.dump() and cfg.reload() # Dump data and reload from disk.

To save your data, run .dump().

>>> cfg.dump()

Have a networked file that you need to save? Use the method save_to_file.

>>> cfg.save_to_file("example.json")

Need to get the raw dict form of a ConfigKey? Use .dump() on that!

>>> cfg.config.dump()
{"a": 1, "b": [1, 2], "c": {"d": 3}
>>> cfg.config.c.dump()
{"d": 3}
