It formalizes the generation of PO (proof obligations) in a Hoare logic for a very basic imperative programming language. It proves the soundness and the completeness of the PO generation both in partial and total correctness. At last, it examplifies on a very simple example (a GCD computation) how the PO generation can simplify concrete proofs. Coq is indeed able to compute PO on concrete programs: we say here that the generation of proof obligations is reflected in Coq. Technically, the PO generation is here performed through Dijkstra's weakest-precondition calculus.""" flags: light-uninstall url { src: "https://github.com/coq-contribs/hoare-tut/archive/v8.5.0.tar.gz" checksum: "md5=de2ae9bce949f357c214f486a71aa685" }

[NOTE] Package coq is already installed (current version is 8.8.2). The following dependencies couldn't be met: - coq-hoare-tut -> coq < 8.6~ -> ocaml < 4.03.0 base of this switch (use `--unlock-base' to force) Your request can't be satisfied: - No available version of coq satisfies the constraints No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

- Command
`opam remove -y coq; opam install -y --show-action --unlock-base coq-hoare-tut.8.5.0`
