We are pleased to announce the first release of SyntaxMacros [1]. SyntaxMacros is an EDSL for constructing compilers out of a collection of pre-compiled, statically type-checked, possibly mutually dependent ``language-definition fragments''. This way of constructing a compiler brings syntax macros for free. This approach is based on a collection of techniques we have previously developed: - transformation of typed abstract syntax trees [2] makes it possible to construct parsers on the fly in a type-safe way - parser combinators [3] make it possible to construct parsers dynamically - first-class attribute grammars [4] make it possible to define semantics in a compositional way More information can be found at: http://www.cs.uu.nl/wiki/Center/SyntaxMacrosForFree Regards, Marcos Viera, Doaitse Swierstra, Atze Dijkstra and Arthur Baars [1]- http://hackage.haskell.org/package/SyntaxMacros [2]- http://www.cs.uu.nl/wiki/Center/TTTAS [3]- http://www.cs.uu.nl/wiki/bin/view/HUT/ParserCombinators [4]- http://www.cs.uu.nl/wiki/Center/AspectAG
