Whitespace is a programming language developed by Edwin Brady and Chris Morris (cim) in 2003. The interpreter ignores any non whitespace characters. Only spaces, tabs and newlines are considered syntax.
The language itself is an imperative, stack based language. The virtual machine on which programs run has a stack and a heap. The programmer is free to push arbitrary width integers onto the stack (only integers, currently there is no implementation of floating point or real numbers). The user can also access the heap as a permanent store for variables and data structures.
