Hi, I am trying to read and understand groff source code, which is - at least for me - not easy. In case of questions, should one ask on the list or are there specialists who are able and willing to help?
An example: In input.cpp there is a linked list class "node_list". Member functions are not commented, but what length(), append(), constructor and destructor do is obvious. However, not so for extract(). One would expect that an element of the list is extracted - as the list is singly linked, the first element - and that the rest of the list stays intact. However, head and tail are set to zero, i.e. the list becomes empty. But what happens to the other elements? Are memory leaks generated? Why is delete_node_list() not called? And btw. why is node_list in input.cpp but delete_node_list() in node.cpp? As I remarked in an earlier post, a short explanation explaining the idea of a class would be VERY helpful. E.g., what does a node-object represent? Here the reader is left in the dark. Cheers, ulrich
