Hi, bindings-DSL[1] is a stable and reliable macro package for FFI. It just got a new tutorial and its repository is now in git. If no one else wants to maintain it, I'll still be looking at issue reports and fixing possible problems, but I've not been actively using Haskell for some time, and won't add anything new or make plans for future changes. The original idea behind bindings-DSL was to build a wide set of community maintained raw bindings to interesting C libraries, on which Haskell programmers could safely depend when creating their own higher level packages. Although that idea never really took off, bindings-DSL itself got some popularity, probably because it makes instancing Storable easy. If you want to take maintenance, you have some options. You could just kill the bindings-* idea and add some flexibility to new macros, which I always avoided to enforce consistency. Or you could keep the original goal, and maybe add a mailing list and a web page where users could request new libraries and discuss solutions to trick issues. A possible plan for version 2 is to be independent of hsc2hs, and use a new syntax instead of C macros. Thanks. Best, Maurício [1]: http://bitbucket.org/mauricio/bindings-dsl
