An extensible config file format
Project description
yay ain’t YAML
yay is a configuration file format built on top of YAML based on our experience with the ConfigParser extensions buildout uses. It adds overlays (one config file including and extending another) and variables.
Consider a config file that looks something like this:
foo:
bar:
baz:
- 1
- 2
- 3
qux: wibble.wobble
quux: wobble
goo:
bar:
baz:
- 1
- 2
- 3
- 4
qux: wibble.cobble
quux: cobble
hoo:
bar:
baz:
- 1
- 3
qux: wibble.yobble
quux: yobble
With yay, this might look like this:
foo:
bar:
baz:
- 1
- 2
- 3
qux: wibble.{:quux}
quux: wobble
goo.copy: foo
goo:
bar:
baz.append:
- 4
quux: cobble
hoo.copy: foo
hoo:
bar:
baz.remove:
- 2
quux: yobble
Using yay
To load yay config from a string you can use the ‘load’ function:
>>> from yay import load
>>> load("""
... foo:
... bar: 1
... """)
{"foo": {"bar": 1}}
If you want to load from a URI (file:// and http:// are supported) then use ‘load_uri’:
>>> from yay import load_uri
>>> load_uri("/etc/someconfig.yay")
{"foo": {"bar": 1}}
The return value in both cases is a standard python dictionary.
