Toka is a concatenative programming language with similarities to Forth. It has two accessible stacks for passing data, a dictionary which maps names to functions, an interpreter, a compiler (generating threaded code), a form of garbage collection, and various functions to aid in debugging and inspecting compiled code. Toka also has a set of optional libraries that extend the core language in many ways.

Toka is distributed under an open-source license.
