standard callback function for wp_list_comments

Question

I know that the code for the comment is generated in Walker_Comment::comment() and for html5 themes in the method Walker_Comment::html5_comment.

But if I try to copy the code from that last method it does not work because of obvious things like

$this->hasParent and so on. I can fix this by using $comment->hasParent

Isn't there somewhere a callback I can use which produces the exact same results as the standard code which will work out of the box?

I am using twenty seventeen and would like to change a few thing. I could hack the class-walker-comment.php but that would be a bad idea.

Answer 1

It sounds to me like you're wanting to extend the default comments walker with your own:

class My_Walker_Comment extends Walker_Comment {
  // giddy up
}

If so, this answer explains it quite well.
