explicit string format as {name_:s} does not work

[martinResearch]

Hi,

It seems that when specifying the format as :s in the formating string then parse does not work:

form = "test_{name:s}"
s = form.format(name="hello")# getting 'test_hello'
parse.parse(form , s) # getting None

Should we add a section elif type == 's': in _handle_field ?

Oof. Unfortunately, parse deviates from format for that one letter, s. In parse it means "whitespace". In format, when used, it means "the default string format".

I actually mis-read the format spec when writing parse and missed the mention of s :(

Ok. Maybe this behaviour could be controlled trough an new optional argument with default value set up to keep default behaviour unchanged to avoid breaking code that relies on it ?

I don't really like that as an option, as it will be very confusing. I think to fix it I'd need to make it a new major release which is backwards-incompatible in this one way.

I see. Is that something you would want to do ?

[r1chardj0n3s]

Not really, but I think I'm going to have to ;-)
