Koka

Established: April 13, 2012

Koka is a function-oriented programming language that seperates pure values from side-effecting computations, where the effect of every function is automatically inferred. Koka has many features that help programmers to easily change their data types and code organization correctly, while having a small language core with a familiar JavaScript like syntax.

The Koka project tries to see if effect inference can be used on larger scale programming. The language is strict (as in ML), but seperates pure values from side effecting computations (as in Haskell). Through the effect types, there is also a strong connection to its denotational semantics, where the effect type of each function has a direct translation to the type signature of the denotational function.

  • You can try out programming in Koka live at the Koka Tutorial.
  • For more technical information, see the slides of a talk presented Lang.Next (April 2012).
  • Read the draft language specification, or browse the library documentation.
