Release of Alt-Ergo 2.4.0

A new release of Alt-Ergo (version 2.4.0) is available.

You can get it from Alt-Ergo’s website. The associated opam package will be published in the next few days.

This release contains some major novelties:

  • Alt-Ergo supports incremental commands (push/pop) from the smt-lib standard.
  • We switched command line parsing to use cmdliner. You will need to use --<option name> instead of -<option name>. Some options have also been renamed, see the manpage or the documentation.
  • We improved the online documentation of your solver, available here.

This release also contains some minor novelties:

  • .mlw and .why extension are depreciated, the use of .ae extension is advised.
  • Add --input (resp --output) option to manually set the input (resp output) file format
  • Add --pretty-output option to add better debug formatting and to add colors
  • Add exponentiation operation, ** in native Alt-Ergo syntax. The operator is fully interpreted when applied to constants
  • Fix --steps-count and improve the way steps are counted (AdaCore contribution)
  • Add --instantiation-heuristic option that can enable lighter or heavier instantiation
  • Reduce the instantiation context (considered foralls / exists) in CDCL-Tableaux to better mimic the Tableaux-like SAT solver
  • Multiple bugfixes

The full list of changes is available here. As usual, do not hesitate to report bugs, to ask questions, or to give your feedback!
