VOLPIC\n\n![logo_white.png](media/logo_white.png#gh-dark-mode-only)\n![logo_black.png](media/logo_black.png#gh-light-mode-only)\n\nVOLPIC, or \"Verifier Of Lifted Pascal In Coq,\" is a platform for lifting \n[FPC](https://www.freepascal.org/)-compatible Pascal code into equivalent \n[Gallina](https://coq.inria.fr/doc/v8.9/refman/language/gallina-specification-language.html)\ncode, which can then be verified in the [Coq Proof Assistant](https://coq.inria.fr/) \nand [extracted](https://coq.inria.fr/doc/v8.9/refman/addendum/extraction.html)\ninto OCaml or Haskell code.\n\nRead the [2024 PLDI SRC extended abstract](https://seashell.charles.systems/publications/VOLPIC_SRC.pdf)\nfor an explanation of the project's purpose, structure, and accomplishments. \n\n## Usage\n\nFirst, build a custom version of FPC based on [my branch](https://gitlab.com/CharlesAverill/source/-/tree/volpic_fpc)*. \nNote, building the compiler requires an existing installation of FPC. \nCheck out the [official installation guide](https://wiki.freepascal.org/Installing_the_Free_Pascal_Compiler).\nBuilding my custom FPC should look like:\n\n```bash\ngit clone https://gitlab.com/CharlesAverill/source/ fpc-source\ncd fpc-source\ngit checkout volpic_fpc\ncd compiler\nmake cycle -j8\n```\n\nThe build will have completed if three binaries `ppc1`, `ppc2`, and `ppc3` have been generated, as well as the final compiler build, denoted by the architecture you built for (ex. `ppcx64`)\n\nTo compile and run the lifter:\n\n```bash\ngit clone https://github.com/CharlesAverill/volpic\ncd volpic/vp_lifter\nopam install . --deps-only\nmake\ndune exec vp_lifter -- \u003cpath_to_program\u003e -fpc-path \"\u003cpath-to-custom-fpc-source\u003e/compiler/ppcx64\" -fpc-args \"-Fu\u003cpath-to-custom-fpc-source\u003e/rtl/units/x86_64-linux/\"\n```\n\n\\* These changes are [merged into FPC main](https://gitlab.com/freepascal.org/fpc/source/-/merge_requests/567),\nbut due to the volatility of the parse tree dump format, I've\nchosen to maintain my own fork of version 3.2.2.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcharlesaverill%2Fvolpic","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcharlesaverill%2Fvolpic","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcharlesaverill%2Fvolpic/lists"}
