Debugging
NOTE: The ECLiPSe debugger has been completely reimplemented
for release 4.1. The debugger is now more modular, easier to extend
and can be equipped with different user interfaces (command line,
graphical, programmable).
It is also more reliable and more scalable with respect to large
applications.
Some features of the old debugger are no longer supported,
they fall into two categories:
- Features that have been dropped for good in order to reduce
time and space overheads and make the system more scalable.
These include the possibility of inspecting exited subtrees,
the availability of instantiations at fail- and leave-ports,
and the tracing of cut and unify ports.
- Features that are desirable and may be reintroduced in some form
in forthcoming releases. These include some support for retrying goals
and the tracing of external predicates.
