pycerberus is a framework to check user data thoroughly so that you can protect
your application from malicious (or just garbled) input data.

* Remove stupid code which converts input values: After values are validated, you 
  can work with real Python types instead of strings - e.g. 42 instead of '42', 
  convert database IDs to model objects transparently.
* Implement custom validation rules: Writing custom validators is 
  straightforward, everything is well documented and pycerberus only uses very 
  little Python magic.
* Focus on your value-adding application code: Save time by implementing every 
  input validation rule only once, but 100% right instead of implementing a 
  dozen different half-baked solutions.
* Ready for global business: i18n support (based on GNU gettext) is built in, 
  adding custom translations is easy.
* Tune it for your needs: You can implement custom behavior in your validators,
  e.g. fetch translations from a database instead of using gettext or define
  custom translations for built-in validators.
* Use it wherever you like: pycerberus is used in a SMTP server, trac macros as 
  well as web applications - there are no dependencies on a specific context 
  like web development.

Changelog
******************************

0.6 (24.11.2014)
====================
- stop using 2to3 for Python 3 compatibility and use exactly the same source
  for all Python versions.
- drop support for Python 2.4 and 2.5
- bug fix: detect validator message keys correctly also when messages are
  specified during validator initialization


0.5 (05.08.2013)
====================
- 'allow_additional_parameters' can now be specified in the schema constructor
  directly as well as a parameter for a declarative schema
- new ForEach validator to validate a list of items with the same validator
- InvalidDataErrors can return a list of errors using '.errors()'. 
- added 'min_length', 'max_length' parameters when instantiating a 
  StringValidator
- All validator messages can be overridden during instantiation by specifying
  ``messages`` attribute,
- new OneOf validator to validate that a value is in a given list of allowed
  values
- added constructor parameter 'filter_unvalidated_parameters' (default True) 
  for SchemaValidators to pass unvalidated parameters instead of removing them
- InvalidDataErrors can "unpack" their errors so that an ordinary dict is used
  as container for sub-errors (instead of another InvalidDataError with an 
  error_dict)
- new BooleanCheckbox validator to validate typical HTML checkboxes
- new API method for all validators: '.copy()' returns a clone of the validator
- new MatchingFields form validator (typically used to verify a password 
  confirmation field)
- new AgreeToConditionsCheckbox validator which works like a BooleanCheckbox 
  but enforces a trueish value
- EmailAddressValidator accepts also '-' and '+' characters in local part

API changes:
------------
 - BaseValidator.error() is deprecated now as the name does not really reflect
   that the method also raised the exception. I added a new method named 
   '.raise_error()' which behaves exactly like the old .error() method. In 
   addition there is a new method '.exception()' which only creates an exception
   instance.
 - IntegerValidator now treats '' and None as empty
 - BaseValidator.to_string() changed to BaseValidator.revert_conversion()
   which reflects the actual purpose better. Validators are not required to 
   return a string anymore.

0.4.2 (05.05.2011)
====================
- More fixes for source distribution because of missing files in tar.gz

0.4.1 (16.04.2011)
====================
- Fix source distribution (distribution_helpers.py were not included)

0.4 (13.04.2011)
====================
- pycerberus now supports Python 3!
- Fix installation/egg generation without babel
- Added a schema which can parse positional parameters from a string into a 
  dict before processing the data like a normal schema would do

0.3.3 (04.07.2010)
==================
- Fix installation issue: pycerberus is actually not zip-safe

0.3.2 (05.06.2010)
==================
- Fix egg file generation: Include all necessary packages in eggs
- added babel support to setup.py
- updated pot file and completed German translation
- fix exception if translations for preferred locale are not available (fall 
  back to english messages)

0.3.1 (07.04.2010)
==================
- Fixed bug due to duplicated message in DomainNameValidator/EmailAddressValidator
- Validator can now strip inputs (False by default)
- StringValidator now also treats '' as empty value (as well as None)

0.3 (27.03.2010)
==================
- Python 2.3 compatibility
- Schema can raise error if unknown items are processed
- Basic domain name validator
- Basic email address validator

0.2 (16.03.2010)
==================
- You now can declare custom messages as a class-level dict
- Added interface to retrieve error details from InvalidDataErrors
- Added validation schemas to validate a set of values (typically a web form).
  Schemas can also inherit from other schemas to avoid code duplication.
- Validators try to make thread-safety violations obvious
- Nicer API to retrieve error details from an InvalidDataError

0.1 (30.01.2010)
==================
 - initial release
