> Add HeapView functionality
> This pulls parts of Joachim Breitner's ghc-heap-view library inside GHC.
> The bits added are the C hooks into the RTS and a basic Haskell wrapper
> to these C hooks. The main reason for these to be added to GHC proper
> is that the code needs to be kept in sync with the closure types
> defined by the RTS. It is expected that the version of HeapView shipped
> with GHC will always work with that version of GHC and that extra
> functionality can be layered on top with a library like ghc-heap-view
> distributed via Hackage.
whoohoo, this is great! I did not not expect that the horrifying (but
maybe not horrible) hack that I wrote so many years ago becomes an
official feature :-)
I’ll be curious in what ways our community will use (or abuse) this
Patrick, you mention that a library like ghc-heap-view will still be
required. Are you interested in updating it to use the new interfaces,
or even take it over completely?
Compatibility with ghc-vis (http://felsin9.de/nnis/ghc-vis/) is
probably the most important goal here. I’m CC’ing the author of ghc-
vis, Dennis. Or maybe ghc-vis should use the GHC-provided wrappers
Dennis, are you still invested in maintaining ghc-vis?
