How to generate random code with antlr4?

[Samuel Leonardo]

Hello,

I've searched for something like this:

--suppose I have a JS3's grammar

so, how can I generate a well formed random code in which the code runs without problem?

For example: instead of get the tokens from a source, I want to make a valid tree with the random rules.

My difficult was that I can't found someone making something like this.

I tried to construct the parsetree, but I found that is not possible cause the tree is read-only.

So, did anyone make something in this sense and can give me a sense of what to do?

Thanks

As the ANTLR4 book  explains when a parser is generated a template for something like a listener is also generated.

 There are examples  in the book for how to set up a main prugram to hook the parts  together so you can feed a lexer with whatever  and analyze its partsetree by exrending the template.
