synopsis: "A plugin to implement functionality similar to `switch` statement in C language"
description: """It allows easier dispatch on several constant values
of a type with decidable equality. Given a type, boolean equality
predicate, and list of choices, it will generate (using TemplateCoq)
an inductive type with constructors, one for each of the choices, and
a function mapping values to this type."""

Dry install 🏜️

Dry install with the current Coq version:

Command

opam install -y --show-action coq-switch.1.0.5 coq.8.5.3

Return code

5120

Output

[NOTE] Package coq is already installed (current version is 8.5.3).
The following dependencies couldn't be met:
  - coq-switch -> coq >= 8.13.0 -> ocaml >= 4.05.0
      base of this switch (use `--unlock-base' to force)
  - coq-switch -> coq >= 8.13.0 -> coq-core -> ocaml >= 4.09.0
      base of this switch (use `--unlock-base' to force)
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-switch.1.0.5
