As part of the upcoming v0.3.10 release of Whiley, I’ve invested considerable effort reimplementing the type system.  This was necessary because, whilst my old implementation generally worked, writing larger programs exposed a lot of issues.  The most interesting aspect of this process is the development of a general-purpose library for representing and manipulating tree . . . → Read More: The Whiley Automata Library (WYAUTL)

Regular Tree Automata

In my quest to understand the theory of recursive types in more detail, the notion of regular tree languages and [[Tree automaton|Tree Automata]] has cropped up.  These have been used, amongst other things, for describing [[XML schema|XML schemas]].  They are also useful for describing recursive types as well!

A nice example of a regular . . . → Read More: Regular Tree Automata
