Great work. However I am have a problem running on windows - it needs librsvg: Prelude System.Vacuum.Cairo> view [1] Loading package mtl-1.1.0.2 ... linking ... done. Loading package parallel-1.1.0.0 ... linking ... done. Loading package glib-0.10.0 ... linking ... done. Loading package cairo-0.10.0 ... linking ... done. Loading package svgcairo-0.10.0 ... can't load .so/.DLL for: librsvg-2-2 (addDLL: could not load DLL) Prelude System.Vacuum.Cairo> Anyone know where I can get this? I have googled around and whilst there is the librsvg development site, there is no sign of a windows DLL. All I can find is some generic site which seems to provide DLLs. I don't trust it.

I am pleased to announce the release of vacuum-cairo, a Haskell library for interactive rendering and display of values on the GHC heap using Matt Morrow's vacuum library.
This library takes vacuum's output, generates dot graph format from it, renders it to SVG with graphviz, and displays the resulting structure using the gtk2hs Cairo vector graphics bindings ... all at the GHCi command line.
This tool is useful for examining Haskell data structures as they are represented directly in the heap. In particular, it makes sharing visible for the first time, as well as unboxed values. It should be useful for teaching Haskell, or for library authors debugging the design of their data structures.
You can see pictures of the rendered display here:

And youtube screencasts of vacuum-cairo in action:

Get it:
cabal install vacuum-cairo
