The context manager would be required both to declare what converters are valid
for the scope, but also because this functionality comes from another package
in addition to pyramid you need to do something to get a different object with
add_route/add_handler.
For non-context use, it'd be something like:
r = routehelper(config, converters=dict(int=converter.Integer(),
month=converter.Integer(min=1, max=12))
r.add_handler('articles', '/articles/{action}/{id:int}', handler=....)
r.add_handler('month_archives', '/archives/{month:month}'...)
That last line is where people's custom converter names vs the marker names
might get a little odd, which is why I was thinking one could assign a
converter that would be used if the marker name was the same. Otherwise for
clarity you'd prolly have this instead:
r = routehelper(config, converters=dict(int=converter.Integer(),
month_conv=converter.Integer(min=1, max=12))
r.add_handler('month_archives', '/archives/{month:month_conv}'...)
Which I guess is fine, and as you mention it does avoid the ambiguity by making
it explicit that something else is happening with the marker.
I do anticipate ppl using the routehelper as a 'partial', which is why many
like the context manager aspect, like how Routes has a submapper:
