this is dirty implementation.

## how to use

- using selectable renderer as renderer factory
- using selectable renderer with view_config settings

### sample

## define selectable renderer
from pyramid_selectable_renderer import SelectableRendererSetup
from pyramid_selectable_renderer.custom import RecieveTemplatePathCandidatesDict
from pyramid_selectable_renderer.custom import SelectByRetvalLeftGen

ValidateTrueOrNot = SelectableRendererSetup(
RecieveTemplatePathCandidatesDict,
SelectByRetvalLeftGen.generate(lambda x : x),
renderer_name = "validate_true_or_not")

## in __init__.py
def includeme(config):
ValidateTrueOrNot.register_to(config) # enable to use selectable renderer

## in view.py
@view_config(route_name="sample.confirm",
renderer=ValidateTrueOrNot({True: "foo:success.pt", False: "foo:failure.pt"}))
def form_confirm_view(context, request):
form = ValidateForm(request.POST):
return form.validate(), {"form": form}
