It also provides a way to embed Coq's terms into λProlog using the Higher-Order Abstract Syntax approach and a way to read terms back. In addition to that it exports to ELPI a set of Coq's primitives, e.g. printing a message, accessing the environment of theorems and data types, defining a new constant and so on. For convenience it also provides a quotation and anti-quotation for Coq's syntax in λProlog. E.g. `{{nat}}` is expanded to the type name of natural numbers, or `{{A -> B}}` to the representation of a product by unfolding the `->` notation. Finally it provides a way to define new vernacular commands and new tactics.""" url { src: "https://github.com/LPCIC/coq-elpi/archive/v1.6.1_8.11.tar.gz" checksum: "sha256=0a065ea27114140f115bd0ccd785e46fc27a842e4a2203d8f2543db3d186a3b5" }

Dry install with the current Coq version:
opam install -y --show-action coq-elpi.1.6.1~8.11 coq.8.12.2
[NOTE] Package coq is already installed (current version is 8.12.2). The following dependencies couldn't be met: - coq-elpi -> coq < 8.12~ -> ocaml < 4.10 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-elpi.1.6.1~8.11
