Coq

Coq 8.7~alpha Gitter

Coq is a formal proof management system. It provides a formal language to write mathematical definitions, executable algorithms and theorems together with an environment for semi-interactive development of machine-checked proofs.

Installation

Go to the download page for Windows and MacOS packages; read the help page on how to install Coq with OPAM; or refer to the INSTALL file for the procedure to install from source.

Documentation

The documentation is part of the archive in directory doc. The documentation of the last released version is available on the Coq web site at coq.inria.fr/documentation.

Changes

There is a file named CHANGES that explains the differences and the incompatibilities since last versions. If you upgrade Coq, please read it carefully.

Availability

Coq is available from coq.inria.fr.

The Coq Club

The Coq Club moderated mailing list is meant to be a standard way to discuss questions about the Coq system and related topics. The subscription link can be found at coq.inria.fr/community.

The topics to be discussed in the club should include:

  • technical problems;
  • questions about proof developments;
  • suggestions and questions about the implementation;
  • announcements of proofs;
  • theoretical questions about typed lambda-calculi which are closely related to Coq.

For any questions/suggestions about the Coq Club, please write to coq-club-request@inria.fr.

Bugs report

Send your bug reports by filling a form at coq.inria.fr/bugs.

To be effective, bug reports should mention the OCaml version used to compile and run Coq, the Coq version (coqtop -v), the configuration used, and include a complete source example leading to the bug.
