I introduced a new function in yaws_api in order to work around the
error handling in binding/1.
binding(Key) ->
case get({binding, Key}) of
undefined -> erlang:fault({unknown_binding, Key});
Value -> Value
end.
I added another function to test for a binding which allows me to
write code to work around this:
binding_exists(Key) ->
case get({binding, Key}) of
undefined -> false;
_ -> true
end.
Claes, If this function or some other way to achieve the same goal
suits you, please add it.
thanks, ke han
