Last week, my first student ever submitted his bachelor thesis „Visualization of Lazy Evaluation and Sharing“ about a tool he created that allows you to investigate the heap of a running Haskell program, including unevaluated values and their sharing properties, in a visual and interactive manner. You can see it in action at the end of the video of my lightning talk about ghc-dup at the Haskell Implementors Workshop this year, and read more about it on Dennis’ ghc-vis web page. I’m quite happy about the result and I think I can get used to have other people implement my ideas and needs :-)
Dennis said he is willing to continue the maintenance of the tool, so give it a shot and bombard him with bug reports and feature requests!
Have something to say? You can post a comment by sending an e-Mail to me at <mail@joachim-breitner.de>, and I will include it here.
