Hi all, buddha 0.6 is now available: http://www.cs.mu.oz.au/~bjpop/buddha/ buddha is a declarative debugger for Haskell 98. The main new feature is an automated front end, so all you have to do is: buddha {- wait a bit -} cd Buddha; ./debug Version 0.6 supports _most_ of the language, the main missing bits are: record syntax (sometimes works, but not fully) deriving statements (you have to expand them yourself, sigh) standard libraries: Ratio Numeric Directory Time Random (because of above) buddha should work with ghc 5.04 or greater, on any unix-a-like machine. The missing bits will hopefully be added in the next few releases. Cheers, Bernie.
