Disciple is an explicitly lazy dialect of Haskell which supports destructive update, computational effects, type directed field projections and some other useful things.
Disciple vs Haskell
- Strict EvaluationOrder is the default, laziness is introduced explicitly.
- Type directed FieldProjections complement type classing.
- All data objects support DestructiveUpdate.
- The EffectSystem tracks what computational effects are being used in a program, without the need for state monads.
- The ClassSystem ensures that effects and destructive update play nicely with laziness.
- ClosureTyping is used to track data sharing, and to preserve soundness in the presence of PolymorphicUpdate.
- Some FurtherReading.
Some example code showing most of the extensions, and its output, core and C-code
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 on linux-x86 and darwin-x86 (tested on Mac OS X 10.5.2)
- Is in a usable alpha state.
Get the Source
Get the latest stable release with darcs:
darcs get http://code.haskell.org/ddc/disciple-alpha1
For thrill-seekers, the development branch (which usually builds ok) is:
darcs get http://code.haskell.org/ddc/disciple-HEAD
