Hi Matthias, Hat supports Haskell 98 plus a few additional libraries, but Unsafe is not one of these libraries. A Google summer of code project is still under way to improve this situation, but that will still take time. The quick fix is to copy a library to your own directory and transform it together with your program. However, direct transformation only works on libraries written in Haskell 98 itself and Unsafe will hardly be of that kind. There are ways for wrapping code not written in Haskell 98, but that requires more handwork (you can see how the core parts of the Haskell 98 libraries are dealt with). Btw, both Malcolm and I are currently in Freiburg so we could easily meet. Ciao, Olaf

Hi,

I just pulled the latest darcs version of hat, compiled it using ghc-6.6.1 and tried to debug a program. Unfortunately, there seems to be no tracing information for standard libraries by default. ... During compilation using "hmake -hat" hat-trans says ...

hat-trans: /usr/local/include/hat-2.05/System/IO/Unsafe.hx: openFile: does not exist (No such file or directory)

Is there a way to generate tracing information for (parts of) the standard libraries? (I realizied there is a script called "start" in the hat root directory?) Or, is there another version of hat that works with ghc-6.6.1?

-Matthias
