13.28.1 New Features

• Added library(json) (see JSON format serialization in the SICStus Prolog Manual) for reading and writing structured data using the JSON (JavaScript Object Notation) serialization format.

  Also added examples that use JSON for communicating between other programming languages and SICStus. Example clients are provided in Python, Java, C#, C, and Prolog.

• It is now possible to suppress fsync() when closing a stream created using the C API function SP_fopen(). This can improve performance when opening and closing many files.
• The spld option --shared can be combined with --static to produce an all-in-one shared library; see Runtime Systems in the SICStus Prolog Manual.
• CLPFD:
  • - Constraint scalar_product/[4,5] is reifiable.
  • - Added constraint scalar_product_reif/[5,6], the reified version of scalar_product/[4,5].
  • - Added constraint value_precede_chain/[2,3], which constrains the order in which values occur in a list.
  • - Generic speedups.
• ZINC: upgraded to and compatible with MiniZinc 2.2.3, with performance improvements.
