synopsis: "Auxiliary Coq library for Ott, a tool for writing definitions of programming languages and calculi"
description: """
Ott takes as input a definition of a language syntax and semantics, in a concise
and readable ASCII notation that is close to what one would write in informal
mathematics. It can then generate a Coq version of the definition, which requires
this library.

trueDry install with the current Coq version:
opam install -y --show-action coq-ott.0.33 coq.8.5.3[NOTE] Package coq is already installed (current version is 8.5.3).
The following dependencies couldn't be met:
- coq-ott -> coq >= 8.6 -> ocaml >= 4.05.0
base of this switch (use `--unlock-base' to force)
- coq-ott -> coq >= 8.6 -> coq-core -> 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-ott.0.33truetrueNo files were installed.
