Hi, For the (probably small) set of people who are interested both in D-Bus and in Haskell, I'm pleased to announce the first release of Bustle, a tool to show diagrams of D-Bus traffic for profiling purposes. It consists of a small C executable to log traffic, and a Gtk+ application which draws diagrams using Cairo. There's no single web page for it yet. http://resiak.livejournal.com/59590.html has slightly more information and context, the release is at http://people.collabora.co.uk/~wjt/bustle/releases/bustle-0.1.tar.gz and the source at git://git.collabora.co.uk/git/user/wjt/bustle.git . Unfortunately, it's not on Hackage, as I haven't written the necessary glue to get Cabal to compile the C executable, but I hope to have time to work on getting Cabal to invoke make appropriately for the next release. Thanks, -- Will
