The fay package

[ Tags: bsd3, development, fay, library, program, web ] [ Propose Tags ]

Fay is a proper subset of Haskell which can be compiled (type-checked) with GHC, and compiled to JavaScript. It is lazy, pure, with a Fay monad, an FFI, tail-recursion optimization (experimental). It implements no type system, for type-checking you should use GHC.


See documentation at or build your own documentation with:

$ cabal unpack fay
$ cd fay-*
$ cabal install
$ cabal install fay-base
$ dist/build/fay-docs/fay-docs
