Changelog

5.0.0 (2016-04-13)

  • Added the fields.InheritableFields base. It allows subclassing and it’s intended for multiple inheritance scenarios. Yes, yes, this enables lots pain and suffering, but some people just like it that way.

  • Simplified the interfaces for the builtin sealers (the required argument is gone as it was redundant, and the remaining arguments are swapped). Now they must be a function that take just two arguments: fields, defaults.

4.0.0 (2016-01-28)

  • Added __all__ and factory conveniences. Removed fields.Factory from the public API since it need some special care with it’s use (it’s a damn metaclass after all).

  • Added make_init_func into public API for advanced uses (combine with factory and class_sealer).

3.0.0 (2015-10-04)

  • Disallowed creating containers with fields with “dunder” names. E.g.: class Foo(Fields.__foo__): is disallowed.

2.4.0 (2015-06-13)

  • Similarly to fields.Fields, added three new bases:

    • fields.BareFields (implements __init__).

    • fields.ComparableMixin (implements __eq__, __ne__, __lt__, __gt__, __le__, __ge__ and __hash__).

    • fields.PrintableMixin (implements __repr__).

  • Improved reference section in the docs.

  • Added fields.ConvertibleFields and fields.ConvertibleMixin. They have two convenience properties: as_dict and as_tuple`.

2.3.0 (2015-01-20)

  • Allowed overriding __slots__ in SlotsFields subclasses.

2.2.0 (2015-01-19)

  • Added make_init_func as an optional argument to class_sealer. Rename the __base__ option to just base.

2.1.1 (2015-01-19)

  • Removed bogus console_scripts entrypoint.

2.1.0 (2015-01-09)

  • Added SlotsFields (same as Fields but automatically adds __slots__ for memory efficiency on CPython).

  • Added support for default argument to Tuple.

2.0.0 (2014-10-16)

  • Made the __init__ in the FieldsBase way faster (used for fields.Fields).

  • Moved RegexValidate in fields.extras.

1.0.0 (2014-10-05)

  • Lots of internal changes, the metaclass is not created in a closure anymore. No more closures.

  • Added RegexValidate container creator (should be taken as an example on using the Factory metaclass).

  • Added support for using multiple containers as baseclasses.

  • Added a super() sink so that super().__init__(*args, **kwargs) always works. Everything inherits from a baseclass that has an __init__ that can take any argument (unlike object.__init__). This allows for flexible usage.

  • Added validation so that you can’t use conflicting field layout when using multiple containers as the baseclass.

  • Changed the __init__ function in the class container so it works like a python function w.r.t. positional and keyword arguments. Example: class MyContainer(Fields.a.b.c[1].d[2]) will function the same way as def func(a, b, c=1, d=2) would when arguments are passed in. You can now use MyContainer(1, 2, 3, 4) (everything positional) or MyContainer(1, 2, 3, d=4) (mixed).

0.3.0 (2014-07-19)

  • Corrected string repr.

0.2.0 (2014-06-28)

  • Lots of breaking changes. Switched from __call__ to __getitem__ for default value assignment.

0.1.0 (2014-06-27)

  • Alpha release.
