I noticed in the OCaml reference manual that it is possible to
load special purpose printing routines for particular types into
ocamldebug. However there is no mention of a facility to
load a special parser for ad hoc queries about variable values
that one might wish to perform within the debugger, using fragments
from the mini-language accepted by a pre-processor.
I am thinking, for example of writing a library that allows routines with
prolog-like variable binding. Suppose a pre-processor is used to allow
embedded definitions in a prolog-like syntax, which are pre-processed
into OCaml source code. For debugging purposes, one would ideally like
to query the variable values using a syntax close to the original source
file.
So my question is "Has anyone has hacked ocamldebug in
this type of way and perhaps has a relevant example to share?"
And my topical thought is that there are potentially substantive
interactions between a sophisticated pre-processor, ocamldebug,
and what the compiler does with the '-g' flag.
