We're building some debugging features into GHCi. This started with Pepe
Iborra's Summer of Code project last year, and more recently Bernie Pope
reworked the breakpoint support during his internship here at MSR Cambridge. We
are actively working on polishing what we have for inclusion in the next major
The GHCi debugger is based on imperative debugging techniques: breakpoints,
single stepping, etc. It's a live debugger rather than post-mortem. We
focussed on accessibilty, rather than functionality: so the debugger is always
on, and it works with everything that you can compile in GHCi. It lacks some of
the advanced debugging features you'll find in Hat, for example, but we hope it
makes up for that by being more broadly accessible.
More information on the debugger is here:
although note that development is ongoing and more features have been added
since the wiki was last updated.
All the debugging functionality is exposed by the GHC API, so it's certainly
possible to build debugging support into an IDE based on GHC.
