Disciple is an explicitly lazy dialect of Haskell which supports destructive update, computational effects, type directed field projections and allied functional goodness.

1 Disciple vs Haskell

Some example code showing most of the extensions, and its output, core and C-code

2 The Disciplined Disciple Compiler

  • Uses a typed core language which includes effect, closure, region and mutability information.
  • This extended type information is used to allow code-transformation style optimizations in the presence of side effects and mutable objects.
  • Compiles via standard C99, so is highly portable.
  • Compiles cleanly under linux-{x86, x86_64} and darwin-{x86, x86_64} (tested on 10.5.4)
  • Is in a usable alpha state.

3 Get the Source

Get the latest stable release with darcs:

    darcs get http://code.haskell.org/ddc/ddc-alpha

For thrill-seekers, the development branch (which usually builds ok) is:

    darcs get http://code.haskell.org/ddc/ddc-head 

Alternatively, download the source tar-ball from Google code
