Constant not found: overload in GF

Question

I was trying to make an overload of function that I have created on GF, but after using the overload function I keep getting this error message.

Am I using this function of GF incorrectly or is there is any new update to this functionality.

Here is what I was trying to do

Sentence = sentence（mkN（“random”））；

oper

sentence：overload {

sentence：N-> Utt =


oun->

mkUtt（mkNP（noun））;

sentence：V-> Utt =

 verb->

mkutt（mkImp（mkV2（verb）））;

};

Thank you~

Answer 1

It looks like your code is a snippet, so there may be a few things preventing your grammar from compiling.

To start, if you check the documentation, you can see that there are two forms for overloading operations.

You are using the syntax to give the types to define the operations. Instead, you should use this existing code with the syntax for defining the operations.

oper sentence = overload {...} ;

The syntax that you are using should be used to define your types before you make the overload oper.
