description: """
We present the complete development in Gallina of the
residual theory of beta-reduction in pure lambda-calculus. The main
result is the Prism Theorem, and its corollary Lévy's Cube Lemma, a
strong form of the parallel-moves lemma, itself a key step towards the
confluence theorem and its usual corollaries (Church-Rosser,
uniqueness of normal forms)."""

Dry install 🏜️

Dry install with the current Coq version:

Command

opam install -y --show-action coq-lambda.dev coq.8.11.dev

Return code

5120

Output

The following dependencies couldn't be met:
  - coq-lambda -> 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-lambda.dev
