Two Decades of Maude
This paper is a tribute to JosĂ© Meseguer, from the rest of us in the Maude team, reviewing the past, the present, and the future of the language and system with which we have been working for around two decades under his leadership. After reviewing the origins and the language's main features, we present the latest additions to the language and some features currently under development. This paper is not an introduction to Maude, and some familiarity with it and with rewriting logic are indeed assumed.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tech
Maude's Internal Strategies
AbstractMaude is a reflective language supporting both rewriting logic and membership equational logic. Reflection is systematically exploited in Maude, endowing the language with powerful metaprogramming capabilities, including declarative strategies to guide the deduction process
Reflection in conditional rewriting logic
AbstractWe recall general metalogical axioms for a reflective logic based on the notion of a universal theory, that is, a theory that can simulate the deductions of all other theories in a class of theories of interest, including itself. We then show that conditional rewriting logic is reflective, generalizing in two stages: first to the unsorted conditional case, and then to the many-sorted conditional case, the already known result for unconditional and unsorted rewriting logic (Reflection in Rewriting Logic: Metalogical Foundations and Metaprogramming Applications. CSLI Publications, 2000). This work should be seen as providing foundations for many useful applications of rewriting logic reflection. The results presented here have greatly influenced the design of the Maude language, which implements rewriting logic and supports its reflective capabilities, and have been used as a theoretical foundation for applications such as internal rewrite strategies, reflective design of theorem proving tools, module algebra and metaprogramming, and metareasoning in metalogical frameworks
LOTOS Symbolic Semantics in Maude
We present a formal tool where LOTOS specifications without restrictions in their data types
can be executed. The reflective feature of rewriting logic and the metalanguage capabilities of
Maude make it possible to implement the whole tool in the same semantic framework, and have
allowed us to implement the LOTOS semantics and to build an entire environment with parsing,
pretty printing, and input/output processing of LOTOS specifications
