there's another curses binding in hmp3, http://www.cse.unsw.edu.au/~dons/code/hmp3/Curses.hsc that i keep meaning to package up, but never do.

Thanks !

There's quite a lot of stuff I don't understand in Curses.hsc ( the use of # chars for example in #const or (P.packAddress "initscr"##) or (#type bool) ) I hope the FFI libs have the answers in the doc.

Those are actually unrelated. "initscr"# is a GHC extension, producing a memory address (effectively an Int) of a string in the .rodata section, like a C string, and usable as arguments for C string functions. (#const FOO) is a directive to the hsc2hs preprocessor, instructing it to find the value of FOO and insert it in the source code here.

P.S. Sorry for not prefixing the title with [Haskell-cafe] -- I'll try to remember it next time.

Don't - mailman does it automatically. Stefan
