Clafer, ClaferIG, ClaferWiki, ChocoSolver, and ClaferChocoIG 0.3.8 Released

by Michał Antkiewicz

The Clafer compiler, Alloy-based instance generator, and wiki 0.3.8 are released on Hackage (clafer, claferIG, claferwiki). The Choco-based instance generator and multi-objective optimizer 0.3.8 is also released. Binary builds are available from Clafer Tools - Binary Distributions.

Major changes include:
  • Allowed having both super and reference parts of a clafer declaration. See pull request.
  • Changed the intersection operator from & to ** to be consistent with ++ and --.
  • Prepared for module system and behavioral Clafer extension.
  • Fixed bugs in HTML and Graph generators.
  • Replaced soft constraint (...) with assertion assert [...]. Soft constraints were never supported in any backend.
  • Phased out Alloy4.1. Alloy 4.2 is now used by default as a compiler mode, for output validation, and instance generation in ClaferIG.
  • The claferwiki.sh script can now run the wiki from sandbox when given the parameter --sandbox.
For detailed changes see pull requests: Clafer, ClaferIG, ClaferWiki
