Mac OS X disk image with relocatable application bundle. Needs xquartz (X11) installed for running the development tools. The bundle also provides the commandline tools in the Contents/MacOS directory. Users of older MacOS versions are adviced to use Macports, Homebrew or install from source. This bundle contains universal (fat) binaries that run natively on Intel (x86_64) and Apple Silicon (M1-3, arm64).

SWI-Prolog version 9.2

The SWI-Prolog 9.2 is the latest stable release. Highlights:

  • Bundled Python bi-directional interface (Janus)
  • C++ interface version 2 (SWI-ccp2.h) covers much more of the SWI-Prolog C API and is more (type-)safe.
  • Sources are now strict C11 and may be compiled using e.g. VS2022 on Windows.
  • Many improvements to the tooling.
    • The profiler can provide accurate port counts
    • The coverage analysis tool can annotate files by line and collect data from multiple threads and Prolog runs.
    • The unit testing tool supports concurrent testing and hiding of output of succeeded tests.
    • The pack manager can deal with version and feature restrictions, plan multiple packs together, build using CMake.
  • Added an option for commandline tools that can be called as swipl <tool> [arg ...]. Provides cli tools for pack management and `.qlf` compilation.
