MetaCoq 1.2 for Coq 8.17

We are happy to announce release 1.2 of the MetaCoq project for Coq 8.17, available both as source and through opam. See the website for a detailed overview of the project, introductory material and related articles and presentations.

The main changes in this new version are (w.r.t. v1.1.1):

• A cleaned-up abstract environment structure for the implementation of the verified type-checker and cleaned-up canonicity and consistency theorems by @tabareau.
• A new quotation library with a work-in-progress proof of Löb's theorem by @JasonGross.
• An integration of the typed erasure phase of the ConCert project by @annenkov and @mattam82.
  Beware, adaptation of the correctness proof is not finished and it is not integrated in the extracted pipeline of MetaCoq Erase yet.
• Reorganization of the packages, separating plugins from theories by @tabareau.

The preprint "Correct and Complete Type Checking and Certified Erasure for Coq, in Coq" presents the development of the sound and complete type checker based on bidirectional typing, the meta-theoretical results (subject reduction, standardization, canonicity and consistency) and the verified erasure procedure of this version of MetaCoq.

MetaCoq integrates Template-Coq, a reification and denotation plugin for Coq terms and global declarations, a Template monad for metaprogramming (including the ability to extract these metaprograms to OCaml for efficiency), a formalisation of Coq's calculus PCUIC in Coq, a relatively efficient, sound and complete type checker for PCUIC, a verified type and proof erasure procedure from PCUIC to untyped lambda calculus and a quotation library. MetaCoq provides a low-level interface to develop certified plugins like translations, compilers or tactics in Coq itself.

You can install MetaCoq directly from sources or using opam install coq-metacoq.
This release will be included in an upcoming Coq Platform.

The current release includes several subpackages, which can be compiled and installed separately if desired:

• the utils library contains extensions to the standard library (notably for reasoning with All/All-n type-valued predicates) (in directory utils, and as coq-metacoq-utils).
• the common libraries of basic definitions for the abstract syntax trees shared by multiple languages (common, coq-metacoq-common)
• the Template-Coq quoting library and plugin (template-coq / coq-metacoq-template)
• a formalisation of meta-theoretical properties of PCUIC, the calculus underlying Coq (pcuic / coq-metacoq-pcuic)
• a verified equivalence between Template-Coq and PCUIC typing (in directory template-pcuic and as coq-metacoq-template-pcuic)
• a total verified type-checker for Coq (safechecker / coq-metacoq-safechecker), usable inside Coq.
• a plugin interfacing with the extracted type-checker in OCaml, providing the MetaCoq SafeCheck <term> command (safechecker-plugin, coq-metacoq-safechecker-plugin)
• a verified type and proof erasure function for Coq (erasure / coq-metacoq-erasure), usable inside Coq.
• a plugin interfacing with the extracted erasure pipeline in OCaml, providing the MetaCoq Erase <term> command (erasure-plugin, coq-metacoq-erasure-plugin)
• a quoting library, allowing the quotation of terms and type derivations along with associated data structures as ASTs/terms (quotation / coq-metacoq-quotation).
• a set of example translations from Type Theory to Type Theory (translation/ coq-metacoq-translations).

A good place to start are the files demo.v, safechecker_test.v, erasure_test.v in the test-suite directory.

MetaCoq is developed by Abhishek Anand, Danil Annenkov, Jakob Botsch Nielsen, Simon Boulier, Cyril Cohen, Yannick Forster, Jason Gross, Meven Lennon-Bertrand, Kenji Maillard, Gregory Malecha, Matthieu Sozeau, Nicolas Tabareau, and Théo Winterhalter.

MetaCoq 1.1 for Coq 8.14

We are happy to announce release 1.1 of the MetaCoq project for Coq 8.14, available both as source and through opam. See the website for a detailed overview of the project, introductory material and related articles and presentations.

This new version integrates:

• Support for primitive integers and floating point values, using the same typechecking mechanism as Coq's kernel, up to the erased lambda-box language.
• Better computational behavior of the safe checker.
• Support for nix and cachix (useful for CI, allows to reuse remotely compiled components)
• Registering of projections for inductive types defined as records
• More efficient eta-expansion transformation using environment maps instead of association lists.

MetaCoq integrates Template-Coq, a reification and denotation plugin for Coq terms and global declarations, a Template monad for metaprogramming (including the ability to extract these metaprograms to OCaml for efficiency), a formalisation of Coq's calculus PCUIC in Coq, a relatively efficient, correct and complete type checker for PCUIC, and a verified type and proof erasure procedure from PCUIC to untyped lambda calculus. MetaCoq provides a low-level interface to develop certified plugins like translations, compilers or tactics in Coq itself.

• a verified type and proof erasure function for Coq (erasure / coq-metacoq-erasure), usable inside Coq or extracted to OCaml as MetaCoq Erase <term>
