CDuce Description

CDuce - Modern XML-oriented functional language with innovative features CDuce is a modern XML-oriented functional language with innovative features. A compiler is available under the terms of an open-source license. CDuce is type-safe, efficient, and offer powerful constructions to work with XML documents.CDuce is fast, functional, type-safe, and conforms to basic standards: XML, DTD, Unicode, XML Schema is partially supported, Namespaces are fully supported.Preliminary benchmarks suggest that despite the overhead for static type verification, a CDuce program can run faster (30% to 60%) than an equivalent XSLT style-sheet (we performed benchmarks with the xsltproc tools from the Gnome libxslt library). Here are some key features of "CDuce":· XML objects can be manipulated as first-class citizen values: elements, sequences, tags, characters and strings, attribute sets; sequences of XML elements can be specified by regular expressions, which also apply to characters strings;· functions themselves are first-class values, they can be manipulated, stored in data structure, returned by a function,...· a powerful pattern matching operation can perform complex extractions from sequences of XML elements;· a rich type algebra, with recursive types and arbitrary boolean combinations (union, intersection, complement) allows precise definitions of data structures and XML types; general purpose types and types constructors are taken seriously (products, extensible records, arbitrary precision integers with interval constraints, Unicode characters);· polymorphism through a natural notion of subtyping, and overloaded functions with dynamic dispatch;· an highly-effective type-driven compilation schema.
