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.
Changelog for yay
=================
0.0.8 (2011-02-18)
------------------
- Replace 'foreach bar as foo' with 'foreach foo in bar'
0.0.7 (2011-02-16)
------------------
- Numbers starting 0 are treated as base 8.
0.0.6 (2011-02-13)
------------------
- Avoid unicode mapping keys where possible - they break **kwargs in Py2.x
0.0.5 (2011-02-09)
------------------
- Add support for nested foreach
- At least for now, support a ruby style .flatten
0.0.4 (2011-02-04)
------------------
- {foo} can be interpreted as a map by YAML. For now, we will use ${foo} to avoid this
- Function calls to python are implemented - there is now range()
- There is now a foo.select key so switch statements can be used
0.0.3 (2011-01-24)
------------------
- Egg packaging fixes
0.0.2 (2011-01-24)
------------------
- Lots more unittests for expression evaluation and expression parsing
- Drop dependency on OrderedDict
0.0.1
-----
- This is still pre-release, no API or language stability guarantees
- Variable resolving is now done in expression tree without a seperate resolve stage
- Uses pyparsing to parse {foo[bar][@.baz > 5]} type syntax
0.0.0
-----
- This is a pre-alpha release to experiment with what we can and can't do.
- New PyYAML Loader subclass for getting ordered maps without ugly !!omap markup
- Resolves {} markup within YAML nodes
- Lazily evaluates .copy, .append and .remove instructions
