Title Lambda Calculator
Description λ-calculator is a lambda expression evaluator for the TI-89. It is a lot like the Haskell programming language in that it is purely functional, uses lazy evaluation, has similar syntax, and provides a lot of functions straight out of Haskell. However, it lacks static typing, pattern matching, list comprehensions, and all but the simplest syntactic constructs. Although limited at its core, λ-calculator has a lot of bells and whistles. It sports a line editor with history. It implements the IO, list, and function monads (see the README.pdf for examples). It also implements a handful of system functions (e.g. ngetchx, which returns the keyboard code of a pressed key). λ-calculator is free software, released under the MIT license. The source code includes plenty of goodies, mainly a C garbage collector and an AVL tree implementation, that could be very useful in other compilers and interpreters for the TI-68k.
