synopsis: "Hoare Type Theory"
description: """
Hoare Type Theory (HTT) is a verification system for reasoning about sequential heap-manipulating
programs based on Separation logic.
HTT incorporates Hoare-style specifications via preconditions and postconditions into types. A
Hoare type `ST P (fun x : A => Q)` denotes computations with a precondition `P` and postcondition
`Q`, returning a value `x` of type `A`. Hoare types are a dependently typed version of monads,
as used in the programming language Haskell. Monads hygienically combine the language features
for pure functional programming, with those for imperative programming, such as state or
exceptions. In this sense, HTT establishes a formal connection in the style of Curry-Howard
isomorphism between monads and (functional programming variant of) Separation logic. Every
effectful command in HTT has a type that corresponds to the appropriate non-structural inference
rule in Separation logic, and vice versa, every non-structural inference rule corresponds to a
command in HTT that has that rule as the type. The type for monadic bind is the Hoare rule for
sequential composition, and the type for monadic unit combines the Hoare rules for the idle
program (in a small-footprint variant) and for variable assignment (adapted for functional
variables). The connection reconciles dependent types with effects of state and exceptions and
establishes Separation logic as a type theory for such effects. In implementation terms, it means
that HTT implements Separation logic as a shallow embedding in Coq."""

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-htt.1.2.0 coq.8.18.0
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.18.0).
[ERROR] Package conflict!
  * No agreement on the version of ocaml:

    - coq-htt = 1.2.0 -> coq (< 8.17~ | >= dev) -> ocaml < 4.02.0
    You can temporarily relax the switch invariant with `--update-invariant'

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