ppTransSmt / ppTransTPTP

Tool translating proof obligations from the POG format to SMT-LIB 2.6 based on the pptrans approach. or to TPTP format based on the pptrans approach.

Dependencies:

• BAST: a C++ library to represent B Abstract Syntax Trees. Depends on Qt5Core, Qt5Xml.

Modules:

• POGLoader: a C++ library to load POG files to memory, using the BAST representation. Depends on BAST, Qt5Core, Qt5Xml.

• PPTRANS: an internal C++ library containing code that is common to the SMT and TPTP encoder programs. It essentially contains the preprocessing code and some utility functions.

• PPTRANSSMT: a C++ program to translate POG files to SMTLIB-2.6 format, based on an extension of the pptrans encoding described in the paper Integrating SMT solvers in Rodin.

• PPTRANSTPTP: a C++ program to translate POG files to TPTP (tff) format, in a similar way to the SMTLIB-2.6 translation.

• test: Test infrastructure. It still needs to be filled with actual tests.

COMPILING

The code uses Qt libraries. It is known to compile with Qt5.12.x and Qt5.15.x under Linux.

Our build process is based on cmake, which produces suitable Makefiles from the CMakeLists.txt provided here. To build the code, run the following commands

cmake .
make

To update the repository and its submodules, use the following command:

git submodule update --init --recursive

If this repository is embedded in a build process managed by CMake, then that process is responsible for processing the CMakeLists.txt file of the BAST library before that of this project.

USAGE

Using ppTransTPTP

  ./ppTransTPTP -i <input.pog> -o <output-tptp-folder>

Scripts

Alternatively, you can use one of the following scripts in the Scripts folder:

• translate.sh : wrapper around pptranstptp that takes as input a POG file and outputs a TPTP file.

• comparison.sh takes as input a folder of POG files and uses both pptranstptp and pptranssmt to generate TPTP and SMTLIB files respectively. It then uses the vampire and z3 solvers to check the validity of the generated files. The results are saved in a CSV file. The script requires the vampire and z3 solvers to be installed and available in the PATH environment variable.

Both scripts will compile the code (using cmake and make) if needed.
