Your code will probably rely on operator declarations and
possibly term expansion. The cross-referencer handles this in
much the same way as
qpc(1): you must supply an
initialization file, using the
Supply meta-predicate declarations for your meta-predicates. Otherwise, the cross-referencer will not follow the meta-predicates' arguments. Be sure the cross-referencer encounters the meta-predicate declarations before it encounters calls to the declared predicates.
The cross-referencer traces from initializations, hooks,
public, and optionally from
user:runtime_entry/1 and module declarations. The
way it handles meta-predicates requires that your application
load its module-files before its non-module-files.
This cross-referencer was written in order to tear out the copious dead code from the application that the author became responsible for. If you are doing such a thing, the cross-referencer is an invaluable tool. Be sure to save the output from the first run that you get from the cross referencer: this is very useful resource to help you find things that you've accidentally ripped out and that you really needed after all.
There are situations where the cross-referencer does not follow certain
predicates. This can happen if the predicate name is
constructed on the fly, or if it is retrieved from the
database. In this case, add
public declarations for
these. Alternatively, you could create term expansions that are
peculiar to the cross-referencer.
