Subject: ocamldebug and abstract record types
Date: Sun, 21 May 2006 00:40:20 -0700 [thread overview]
Message-ID: <B0430106-0F99-4458-BEA9-54E9EE8B23A7@akalin.cx> (raw)
At the risk of starting another flamewar, I have another question. I
notice that if I have a record type that's defined in an .mli file, I
am able to print objects of that type and see its contents in the
debugger. However, if I make that type abstract (only defining it in
the .ml file), I am unable to do so, instead seeing "<abstr>", unless
I am in the .ml file where the type is defined.
Surely this information is available to the debugger from anywhere in
the program? Currently I make most of my types non-abstract simply
because it is impossible to debug my programs without being able to
check record contents, a practice which I would like to avoid having
to do. I am used to gdb, which prints out all a struct's contents
regardless of protected/private modifiers, or Perl, which provides a
similar facility with the Data::Dumper module.
I am aware that the debugger lets you load printing functions, a
facility which I am now exploring. Although my first impression is
that it requires a non-trivial amount of work, both on the coding and
debugging side.
Incidentally, how sophisticated is the debugger planned to be? Is it
only supposed to be used for quick-and-dirty debugging and not as a
replacement for the toplevel?
