Simple Ansible-style variable parsing for Confuse config files using Jinja2.
pip install confuse-jinja
# config.yml
asdf:
blah: asdf{{ C.other.thing }}
nested: '{{ C.asdf }}' # need to quote if you start with a '{'
other:
thing: 456
import confuse
import confuse_jinja
confuse_jinja.enable() # now you can use jinja2 templates inside your config values
config = confuse.Configuration('asdf')
config.set(confuse.load_yaml('config.yml'))
assert config['asdf']['blah'].get() == 'asdf456'
assert config['nested'].get() == {'blah': 'asdf456'}
- for any config values that are a string, render it as a jinja2 template
- try to parse rendered string as python using ast functions graciously pulled from ansible's source code
- if a valid python object (list, dict, etc.) can be parsed from the string the object will be returned, otherwise it will return as a string.
- test in a yaml file (possible syntax errors)
- enable on a config-by-config object basis instead of globally.
- would need to replace
ConfigView.__getitem__
for a single Config - would require using
self.Subview
instead of globalSubview
- would need to replace
