{"id":253146,"name":"z3","ecosystem":"hackage","description":"Bindings for the Z3 4.x Theorem Prover (https://github.com/Z3Prover/z3).\n\nZ3.Base.C provides the raw foreign imports from Z3's C API.\n\nZ3.Base does the marshaling of values between Haskell and C,\nand transparently handles reference counting of Z3 objects for you.\n\nZ3.Monad provides a convenient monadic wrapper for the common usage scenario.\n\nExamples: https://github.com/IagoAbal/haskell-z3/tree/master/examples\n\nChangelog: https://github.com/IagoAbal/haskell-z3/blob/master/CHANGES.md\n\nInstallation:\n\nUnix-like: Just be sure to use the standard locations for\ndynamic libraries (/usr/lib) and header files (/usr/include),\nor else use the --extra-lib-dirs and --extra-include-dirs Cabal flags.\n\n(Hackage reports a build failure because Z3's library is missing.)","homepage":"https://github.com/IagoAbal/haskell-z3","licenses":"BSD-3-Clause","normalized_licenses":["BSD-3-Clause"],"repository_url":"https://github.com/IagoAbal/haskell-z3","keywords_array":["bit-vectors","bsd3","formal-methods","library","math","smt","theorem-provers","Propose
