Release 3.2.2

• General:
  • Update parser to merge patterns and paths, as sequencing is important. Fixes #42.
  • Add :all_vars option to parser, which will emit a (project () (...)) when a SELECT * is parsed. This currently defaults to false, but will become true, or non=optional in a future release. This causes SELECT * to project all in-scope variables.
  • Better error detection when using variables from groups that are not exported.
  • Fix result formats for boolean values.
  • Implements SPARQL 1.1 Protocol using the new SPARQL::Server Sinatra application.
• Documentation
  • Update documentation links to use gh-pages, and add action to publish gh-pages from Yard docs.
• SPARQL 1.2
  • Updates to support SPARQL 1.2 SEP-002 for XPath date/time/dateTime/duration functions and operations.
  • Parse property path ranges. (e.g., :a :b{1,2} :c. For SPARQL 1.2 SEP-0003.
  • Add path_range and path_zero operators to support path min/max.
• SPARQL*
  • Use qtriple for quoted triples instead of triple, which can be confused with the TRIPLE function.
  • Restore Operator::Triple, and add SXP parsing rules to distinguish (triple) function from pattern. As a pattern, it can appear as the child of the following: BGP, Construct, Delete, DeleteData, DeleteWhere, Graph, Insert, InsertData, or Path.
  • Add qtriple for quoted triples, with support of the quoted attribute of an RDF::Statement/Pattern.
