This strategy has been followed by the pilot project that has been
described in . In this project we have ported a crucial subset of the
Clean Object I/O library to Haskell. The Clean Object I/O library is used
for major projects such as the Clean IDE and the Clean theorem prover
SPARKLE by Maarten de Mol.
The pilot port has been done on a Windows platform, so that we could reuse
the primitive implementation layer. To port it to a more Unix friendly
environment, I guess Manuel Chakravarty's GTK binding library is very well
You can find the results from the pilot project in the GHC CVS repository at
The current state of affairs is due to severe lack of time a little
unsatisfactory... To make this project manageable, it would be good to have
some kind of automatic translator (nothing fancy, just a specialised
translator from Clean Object I/O to Haskell Object I/O would do) that will
derive the Haskell version from the Clean version that I do maintain. I
haven't had time yet to make such a tool.
