History

  • Make getattr_path more in line with the standard library getattr semantics

    If a default value is provided, return that on missing attributes

    If no default value is given, give a more detailed error message of what was missing

  • Added the special case of the empty path returning the object

5.6.0 (2020-12-02)

  • Fix corner case of class Meta failing to merge with None namespace values

5.5.0 (2020-08-21)

  • Include tri.struct 4.x as possible requirement

5.4.1 (2020-06-34)

  • Optimizations

5.4.0 (2020-04-16)

  • Minor bug fix on trailing comma explanation TypeException
  • Fix bug when nesting @class_shortcut with same name i sub classes
  • Refactor code to separate modules to get better stack traces

5.3.0 (2020-04-01)

  • Enable @class_shortcut to override baseclass shortcuts with the same name.
  • Fix @with_meta failing on method declarations with @staticmethod declaration

5.2.0 (2020-02-28)

  • The namespace merge is narrowed to only affect the @with_meta case.
  • Handle calling Namespace with call_target__attribute=None

5.1.1 (2020-02-11)

  • Improve namespace merge in @with_meta to not trip up @declarative

5.1.0 (2020-02-11)

  • Fix @with_meta argument injector to merge namespaces

5.0.1 (2019-02-03)

  • A minor update to the documentation generation to make it play nice with rST

5.0.0 (2019-01-30)

  • Added private field to shortcuts: __tri_declarative_shortcut_stack. This is useful to be able to figure out a shortcut stack after the fact
  • get_callable_description thought stuff that contained a lambda in its string representation was a lambda
  • Removed all deprecated APIs/behaviors:
    • creation_ordered
    • The promotion of string values to keys in Namespace
  • Much improved error messages

4.0.1 (2019-10-23)

  • Bugfix to correctly handle Namespace as callable/not callable depending on content

4.0.0 (2019-10-11)

  • get_meta() now collects extra arguments in a Namespace to get consistent override behaviour.
  • should_show no longer accepts a callable as a valid return value. It will assert on this, because it’s always a mistake.
  • Added evaluate_strict and evaluate_recursive_strict that will not accept callables left over after the evaluation. If possible prefer these methods because they will stop the user of your library from making the mistake of not matching the given signature and ending up with an unevaluated callable in the output.

3.1.0 (2019-06-28)

  • Fixed issues when Namespace contained a key called any of items, values, keys, or get
  • Removed sorting on Namespace kwargs that isn’t needed in python 3 anymore. The sorting also destroys the given order which can be surprising
  • Removed old obsolete functions collect_namespaces, extract_subkeys, and setdefaults

3.0.0 (2019-06-10)

  • Renamed module from tri.declarative to tri_declarative. This is a breaking change
  • Dropped support for python2

2.0.0 (2019-04-12)

  • Fixed get_signature cache to not pollute struct-like dicts
  • New call_target semantics for class method shortcuts, this is a potential breaking change

1.2.1 (2019-13-15)

  • Improved documentation output

1.2.0 (2019-13-14)

  • Add get_members function to enable reuse of @declarative attribute collection
  • Add @class_shortcut decorator to enable @with_meta aware class shortcuts

1.1.0 (2018-11-22)

  • Added generate_rst_docs function.

1.0.6 (2018-09-28)

  • Shortcut is now a special case when merging Namespace objects. When already in a Namespace, a Shortcut now get overwritten by setitem_path(), not merged into the written value.

1.0.5 (2018-09-21)

  • Fix broken handling of empty key

1.0.4 (2018-09-21)

  • Cleanup Namespace path logic and make sure it is symmetrical and tested.
  • Added deprecation warning on string to dict promotion on namespace merge.

1.0.3 (2018-06-26)

  • Fixed release functionality

1.0.2 (2018-06-18)

  • Don’t support RefinableObject in evaluate_recursive. This was a mistake.

1.0.1 (2018-06-15)

  • Support RefinableObject in evaluate_recursive.

1.0.0 (2018-05-23)

  • Cleanup deprecation warnings from inspect.getargspec

0.34.0 (2017-08-21)

  • Fix bug in 0.33.0 when promoting callable to Namespace.

0.33.0 (2017-08-21)

  • Fix bug when promoting callable to Namespace.
  • Fix handling of EMPTY marker.

0.32.0 (2017-07-04)

  • Added promoting callable namespace members to Namespace with call_target in setdefaults_path.

0.31.0 (2017-06-15)

  • Improve sort_after to allow more combinations of after=… specifications. e.g. by name of an entry also moved by spec.
  • Changed name of first parameter of setdefaults_path to __target__ to avoid collitions with namespace parameters.
  • Added RefinableObject base for reuse by classes wanting to be able to be configured via constructor kwarg parameters in a declarative fashion. (The namespace of possible constructor overrides are declared with Refinable() for values and the decorator @refinable for methods.
  • Added first incarnation of crawling the definitions to recursively find available parameters on objects and their aggregates.
  • Added Shortcut abstraction to be able to find pre-defined set of overrides of RefinableObject classes.

0.30.0 (2017-02-10)

  • evaluate and evaluate_recursive also works for methods as well as for functions.

0.29.0 (2016-09-12)

  • Fixed loop detection in flatten for Namespaces. This resulted in data corruption.

0.28.0 (2016-07-15)

  • Added Namespace subclass of tri.struct.Struct to explicit capture the path splitting semantics. (And added method for flattening a Namespace back to path notation.)

0.27.0 (2016-07-13)

  • Fix bug in evaluate signature detection with optional arguments. (lambda a, b=17: a+b was correctly matched but lambda b, a=17: a+b was not)

0.26.0 (2016-05-06)

  • Added EMPTY marker to setdefaults_path to avoid mixup when empty dict is provided in function defaults.

0.25.0 (2016-04-28)

  • Added @dispatch decorator

0.24.0 (2016-04-20)

  • Fix bug in setdefault_path tripping up on key ordering.
  • Dropped namespace_factory keyword argument to setdefaults_path not likely ever beeing used.

0.23.0 (2016-04-15)

  • setdefaults_path now accepts multiple default dicts. (To simplify the pattern of shortcuts in tri.form, tri.query and tri.table where we now will end up with: new_kwargs = setdefaults_path(Struct(), kwargs, dict(….))

0.22.0 (2016-03-24)

  • sort_after() should produce an error when attempting to sort after non-existant keys
  • Tweaked namespace merge in setdefaults_path

0.21.0 (2016-03-01)

  • Fix corner case in collect_namespaces where one parameter imply a value and others imply a namespace.
  • Added setdefaults_path helper with __ namespace traversal.

0.20.0 (2016-02-29)

  • Added assert_kwargs_not_empty convenience function.
  • Improved documentation.

0.19.0 (2016-01-12)

  • When making instances of a class decorated with @declarative the declared values are copied (shallow) before being passed to __init__.
  • Instances will get an own copy of the declared attributes written to their __dict__
