Need a way to "omitempty"

[sheki]

Right now gorilla/schema does not have a way to omit non present values to empty.
For example :

type params struct {
   Username string `schema:"name"`
   Password string `scehma:"password,setempty"`
}

If the input map does not contain the key "password" it should set it to an empty value if the tag is provided.

We are running into an issue with this right now.

You could just set the field to an empty string prior to decoding.

The behaviour is pretty consistent with how other decoding modules such as encoding/json and encoding/xml work.

I agree that this behaves like json/encoding, but I still think having a an additional flag will be useful

Sorry, I don't agree, you can already achieve what you need without adding any additional flags to the package by just setting the field to the default value you want before decoding.
