Hello,
Over the holidays I wrote a small GHC plugin to help me do some low-level optimizations of Haskell code. I thought it might be of use to other people too, so please try it out!
When enabled, the plugin will save the Core generated by GHC in JSON format, and also render it in HTML for human inspection.
The plugin is available on Hackage: http://hackage.haskell.org/package/dump-core
The instructions on how to use it are in the README file. You may also read about it at the github page: http://hackage.haskell.org/package/dump-core
There are many things that could probably be improved, just let me know. Also, if you are good at design, I could use some help making things look prettier :)
Happy hacking, -Iavor

This looks fantastic, Iavor. I have often wanted something like this. It would be nice if the package would also expose a library providing the types along with FromJson instances so one can load a dump into ghci for further inspection. I've also long wanted a tool to easily fuzzily compare pairs of core dumps. This could be a great tool for enabling this. Cheers, - Ben
