synopsis: "A generic goal preprocessing tool for proof automation tactics in Coq"
description: """
Trakt is a Coq plugin that provides a new Coq tactic, trakt, for preprocessing goals before handing them to a proof automation tactic, as well as Coq commands to fill a knowledge database before calling the tactic.
Drawing inspiration from the zify tactic in the Coq standard library, it acts like a type-level funnel by casting all the possible values in the goal into a given target type. It can also express logic in Prop or bool according to the user's choice.
The translation is implemented in Coq-Elpi. It is certifying (it leaves no proof obligation), generic (the translation does not focus on a precise theory, it is determined by the parameters and user knowledge), and efficient (it tries to make sparse use of Coq conversion).

trueDry install with the current Coq version:
opam install -y --show-action coq-trakt.1.1 coq.8.5.0[NOTE] Package coq is already installed (current version is 8.5.0).
The following dependencies couldn't be met:
- coq-trakt -> coq-elpi < 1.15~ -> ocaml >= 4.07
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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-trakt.1.1truetrueNo files were installed.
