There is also the Scsh manual. Best wishes Stephen The Scsh manual is worth reading just for the introductory material. Part of the problem is that both Clean and Scheme have relatively easy and powerful 'eval' ability. (Esther exploits the interesting feature of Clean that lets you serialize functions to disk.) Haskell doesn't, so much. The GHC API isn't too great to work with here; it's hard enough to evaluate straight Haskell fragments, and to serve as a shell, you really need new syntax; for example, you want literals for program names. (Who would use a shell which forces you to write 'run ghci [foo.lhs]', instead of 'ghci foo.lhs'?) But many filenames break in Haskell; 'ssh-agent', 'g++-4.4', 'bf_tar', etc. -- gwern ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hi Gwern The Scsh manual is worth reading for the Acknowledgements section - which is somewhat famous. Looking over them both it seems most of the material in the paper is covered in the manual. Esther is shipped as a project with Clean2.2 although I think it only works on Windows - the last time I looked at the code I got the impression that it had diverged a bit from the the Famke / Esther papers.

Unfortunately though, h4sh seems to be broken, for one, there's no fps package (apparently required), and hsplugins won't build with 6.12.1.

The ability to load and unload compiled code in a running application? Perhaps hint offers that now ? Specifically, I believe you could have a function 'foo', and you could load a new version of 'foo' while the programming was running, and the running code would start using the new version instead.. I can't quite remember the details though.
