synopsis: "IO monad for Coq"
description: """
This library provides tools to implement IO programs directly in Coq, in a
similar style to Haskell. Facilities for formal verification are not included.
IO is defined as a parameter with a purely functional interface in Coq,
to be extracted to OCaml. Some wrappers for the basic types and functions in
the OCaml Pervasives module are provided. Users are free to define their own
APIs on top of this IO type."""

trueDry install with the current Coq version:
opam install -y --show-action coq-simple-io.1.5.0 coq.8.7.2[NOTE] Package coq is already installed (current version is 8.7.2).
The following dependencies couldn't be met:
- coq-simple-io -> coq >= 8.8 -> ocaml >= 4.09.0
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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-simple-io.1.5.0truetrueNo files were installed.
