Fixed issue: custom help messages inValidationError using several variables were not rendering to string correctly and instead were displayingError while formatting the help message. Fixes#58

• packaging improvements: set the "universal wheel" flag to 1, and cleaned up thesetup.py. In particular removed dependency tosix for setup. Fixes#57

• Package was made PEP561 compatible. Fixed#55

• Improved type hints for decorators so that they do not make the decorated item loose its type hints. Fixed#56

• Removed usage of@with_signature in favour of stub file in theentry_points_annotations.py. Fixed#50

Better syntax for*validation_func:

• you can provide atuple(<callable>, <help_msg>, <failure_type>) to define a single failure raiser (before only(<callable>, <help_msg>) or(<callable>, <failure_type>) were supported). Fixes#33

• you can provide adict-like to define several validation functions, where the key and values can contain<callable>,<help_msg>,<failure_type>. For example{<help_msg>: (<callable>, <failure_type>)} is supported. Fixes#40.

• nested lists are however not supported anymore

• the<callable> can now either have signaturef(v),f(*args),f(*args, **ctx) orf(v, **ctx), where**ctx can be used to receive contextual information. Fixes#39

validation_lib should be imported explicitly

• symbols fromvalid8.validation_lib are not imported automatically at package root anymore. You need to import them fromvalid8.validation_lib. This speeds up the library's import especially when you do not use the built-in functions. So instead offrom valid8 import is_even you should now dofrom valid8.validation_lib import is_even (orfrom valid8 import validation_lib as vlib +vlib.is_even). Fixed#35.

Major exceptions refactoring

• the main validation function in aValidator is now always a failure raiser, even if a single callable was provided. This major design choice made many simplifications possible in particular the string representation of exceptions (below). Fixes#44

• The string representation ofValidationError andValidationFailure was greatly improved. In particularValidationError does not display the name and outcome of the validation function anymore (since it is always a failure, see above), andValidationFailure now has a "compact" string representation option in a newto_str() method, used in composition messages to simplify the result. Composition failures are also represented in a more compact way.

• failure_raiser moved tobase submodule with its associated type hintsValidationCallable andValidationCallableOrLambda. It now only accepts a single validation function argument ; this is more intuitive and separates concerns with the other higher-level functions. If you used it with several inputs in the past, you can useand_(...) instead, it will be strictly equivalent to the old behaviour.

• new@as_failure_raiser decorator to create a failure raiser by decorating an existing validation function. Fixes#36.

• WrappingFailure does not exist anymore, it was merged withFailure class for architecture simplification. So there are two main exception classes in valid8 now:ValidationError andValidationFailure. When the validation callable does not raise an instance ofValidationFailure itself, theInvalid subclass is used. Fixes#41

Misc

• assert_subclass_of now exposed at root level (for consistency withassert_instance_of, to be used in the context manager entry point)

• Added__version__ attribute to comply with PEP396, followinghttps://smarie.github.io/python-getversion/#package-versioning-best-practices. Fixes#38.

• result_is_success is now inlined and does not use a set expression anymore. Fixed#37

• Improved all examples ofFailure in the validation lib to show how a better practice where thehelp_msg stays at class level but can be overridden failure instance by failure instance.

• Removedlength_betweenopen_left/right arguments as it does not make sense, to continue fixing#29

• new subpackageutils where all util submodules now live

• New submodulecommon_syntax where all the logic to handle the*validation_func input syntax resides

• some type hints renamed for clarity:

  • before:ValidationFuncs /ValidationFunc /CallableType /Callable
  • now:OneOrSeveralVFDefinitions /ValidationFuncDefinition /ValidationCallableOrLamba /ValidationCallable.
  • ValidationFuncs still exists as a short alias forOneOrSeveralVFDefinitions.

• fixed a few type hints too: tuples with unlimited length were not declared correctly. Now using the ellipsisTuple[<type>, ...].
