description: """
Equations is a function definition plugin for Coq, that allows the
definition of functions by dependent pattern-matching and well-founded,
mutual or nested structural recursion and compiles them into core
terms. It automatically derives the clauses equations, the graph of the
function and its associated elimination principle.

Dry install 🏜️

Dry install with the current Coq version:

Command

opam install -y --show-action coq-equations.dev+HoTT coq.8.11.dev

Return code

Output

[NOTE] Package coq is already installed (current version is 8.11.dev).
The following dependencies couldn't be met:
  - coq-equations -> coq >= dev
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-equations.dev+HoTT
