Features

  • detection of integer variables and integer predicate parameters
  • command-line option --no-detect-integers to disable integer variable detection
  • new simplification rule applying to integer variables
  • support for declaring functions integer with the #external directive

Bug Fixes

  • fixes incorrect translation of unsupported choice rules with multiple elements by returning an error instead
  • fixes precedence of intervals by enclosing them in parentheses

0.1.8 (2018-04-20)

Features

  • more and advanced simplification rules
  • adds support for exponentiation (power) and modulus (absolute value)

0.1.7 (2018-04-08)

Features

  • support for declaring placeholders with the #external directive

Internal

  • drops Boost dependency in favor of the header-only command-line option library cxxopts

Features

  • unique IDs for all variables (user-defined variables are renamed)
  • support for hiding predicates from completed output by using #show statements
  • more simplification rules with --simplify

Features

  • simplification of output formulas (optional)
  • command-line option --simplify to turn on simplification

Bug Fixes
