Usage

This package contains a Sparql11AdjustParser that is able to parse SPARQL 1.1 queries including the builtin function ADJUST:

const parser = new Parser();
const abstractSyntaxTree = parser.parse(`
SELECT ?s ?p (ADJUST(?o, "-PT10H"^^<http://www.w3.org/2001/XMLSchema#dayTimeDuration>) as ?adjusted) WHERE {
  ?s ?p ?o
}
`);
Copy

This parser is a simple grammar extension to the parser-sparql-1-1. As such, most, if not all, documentation of that parser holds for this one too.
