Companies supporting the project can get 6 to 12 days of consultancy, on-site workshops and other perks. ================= What is all about ?? Lan.d.s is a new solution for language design. From general purpose languages like Lise (short for (list (embedding)) to Domain-Specific Languages using the MOODs framework, and everything else in between. Lan.d.s is build around the formalism of Multi-Ordered Grammars, which are a possible alternative to CFGs and PEGs in wider use today. Multi-ordered grammars (or simply MOGs) aim for a better exploration of ambiguity, recursion, ordering and associativity during language design. They can be parsed using the Gray Algorithm. After parsing in order to ease the production of executable code Lan.d.s introduces the Abstract Syntax Language (ASL), which is an OO solution for compile-time meta-programming. Finally in order to promote language extension and re-use, Lan.d.s employs GrammarTraits, as units of composition for both MOG rules and ASL actions. ================= Some random highlights for the impatient: * Object subclass: #Prediction uses: Future syntax * Languages are everywhere, they are all around you, even now in this very sentence. * Study SICP with a Xerox flavor, while re-inventing some Bell-labs utilities. * TOC-Board, the TOC for your next talk ;) Enjoy ! <Theory-and-Applications-Of-Multi-Ordered-Grammars.pdf><Lands-Alpha-All-Along-The-Language-Tower.png>
