A translator for logic programs with constraint atoms to CASP.

Check the releases page for pre-compiled binaries of lc2casp and an extended version of the paper about default reasoning with constraints.

• Releases

The basic usage to ground, translate, and solve logic programs with constraint atoms is

gringo PROGRAM | lc2casp | clingcon

The translator requires that gringo and clingo as well as clingcon are build first.

To build gringo and clingo, execute

cd third_party/gringo
scons --build=release

In case more configuration is necessary, please check the README and INSTALL documents of the gringo project. The gringo executable that can be used to ground the examples is available in third_party/gringo/build/release/gringo.

To build clingcon, execute

cd third_party/clingcon
make

The clingcon executable that can be used to solve the examples is available in third_party/clingcon/build/bin/clingcon.

If both projects have been compiled successfully, the translator can be build

make

The translator executable lc2casp to rewrite the gringo output is available in the top level directory afterward.
