Version 2.3.1

The action to convert attrs classes to dicts checks if a value is set to its default using the == operator. In some cases this doesn't work; this patch won't check mandatory fields.

Version 2.3.0

Technically a bugfix, but it also technically breaks pickling compatibility.

• Fixes handling of private fields in attrs classes.

Version 2.2.0

Release notes:

• Adds experimental support for classes derived from typing.Generic.
• Expands supported pythons to include 3.4
• Factors some error support into json_syntax.errors
• Factors some typing support into json_syntax.types

Maintenance notes:

• Added configuration and documentation for testing via dephell docker commands.
• Some cleanup of the unit tests for annotations

Version 2.1.1

This adds the new string verbs to the rules in extras.flags, as well as making them compatible with Python 3.5.

Version 2.1.0

Release notes:

• Add separate verbs for encoding and decoding strings to be used by homogenous mapping types.
• Drop read_all as we shouldn't try to save init=False keys in attrs.
• Make sure helpers._Context is stringifying context items.

Version 2.0.2

Release notes:

• Improves extras.dynamodb
• Fixes TypedDict

Version 2.0.0

New:

• New dynamodb ruleset in extras
• Add preliminary TypedDict support for when 3.8 lands.
• Adds a RLockCache that uses reentrant locks.
• Refactors product type (attrs, dataclass, named tuples) especially for better error messages

Potentially breaking changes:

• The examples directory is now extras
• Add access method to SimpleCache that RuleSet will call.
• Some actions in action_v1 are expecting the new Attribute object instead of a tuple

Version 1.0.1

This makes a small correction to the behavior of Enums; using indexing to look up members rather than relying on the __members__ dunder it uses the type directly.

To override it you'd need to subclass EnumMeta, but that's actually pretty easy.

Version 1.0

This tweaks 0.3.0 to add some convenience methods to the RuleSet class, and adds some docstrings.

Version 0.3.0

• Adds the show_pattern verb to construct a Pattern object describing what the JSON looks like.
• Adds the is_ambiguous method to RuleSet to determine if a type description with Unions is ambiguous
• Adds a property test to prove round-tripping works with the standard rules.
