Contribution to validators

[Pierre-Antoine Roiron]

Hi,

I'm working on a web2py project, and I'm slowly learning. Thanks for all the ressources available. I needed a new DAL validator like IS_UPPER() but based on title(), so I looked over the source files and saw validators.py. I added the class IS_TITLE() to it but it doesn't seems to be enough to make it work on my model. Candid developer... What should I do ?
I'd like to contribute to the validators.py file, so here's a new class to add if web2py's team agree :

class IS_TITLE(Validator):
    """
    Converts to title ::


        >>> IS_TITLE()('abc-def ghi')
        ('Abc-Def Ghi', None)
        >>> IS_TITLE()('é')
        ('\xc3\x89', None)

    """


    def __call__(self, value):
        return (value.decode('utf8').title().encode('utf8'), None)

And here's the documentation for the book :

IS_TITLE

This validator never returns an error. It converts the value to title case.

requires = IS_TITLE()

It seems like I forgot to add IS_TITLE() to the __all__ declaration or whatever is its name in validators.py (I am not an developer, sorry for the inapropriate vocabulary). It seems to work for now.

I am still open to some explanations (what is validators.pyc).
