[Caml-list] Backtracting exceptions in toplevel

[C. Fr]

Hello everyone,

It there a way to get a backtrace for exceptions occurring in the toplevel
(for example, getting more information when the stack blows)? I’ve read that
there was an equivalent of the -b option that ocamlrun uses, but I couldn’t
find any subsequent information on it.

Thanks!

There is Printexc.get_backtrace
since ocaml 3.11 I think.

In 3.11.x there is Printexc.record_backtrace which controls the -b
flag, and Printexc.get_backtrace to get the trace of the last
exception.

If you want to see backtraces printed automatically in the toplevel,
try my patch:
