The sparkle-g project has released a pretty printer and syntactic validator for the SPARQL 1.1 Query and Update Language . The pretty printer and syntactic validator is based on the ANTLR framework for constructing recognizers, interpreters, compilers, and translators. The generation of the formatted output text relies on the StringTemplate template engine. ANTLR and StringTemplate have both been designed and crafted by Terence Parr, a professor of computer science at the University of San Francisco.
