json {struct,[{key,val}]} is unnecesarily verbose #73

Closed GoogleCodeExporter closed 8 years ago

What is the point of {struct,obj} tuple? If the mochijson2:json_encode
function is modified to:

json_encode([{_,_}|_] = Props, State) ->
    json_encode_proplist(Props, State);
json_encode(Array, State) when is_list(Array) ->
    json_encode_array(Array, State);

It works just fine without it.

It's so that you can distinguish between a 0-element array and an object with 
no properties.

Ahh of course. A shame that the two mongodb drivers use the opposite solution
([{_,_},..] = object and {array,[...]}). Would you guys be willing to have the
json_encode function be more permissible?

json_encode([{_,_}|_] = Props, State) ->
    json_encode_proplist(Props, State);
json_encode({struct, Props}, State) when is_list(Props) ->
    json_encode_proplist(Props, State);
json_encode(Array, State) when is_list(Array) ->
    json_encode_array(Array, State);
json_encode({array, Array}, State) when is_list(Array) ->
    json_encode_array({array,Array}, State);

If you submit a patch with passing tests then I'll take a look at adding it

Patch attached. I added encoding tests for objects without struct tuple.

After using my patch in multiple projects and testing with many possible json 
document combinations, I since found one bug. Patch attached. It's a very 
change simple.
I'm sorry for posting it so late, I forgot and the issue email reminded me.
