Rocq
What it is
Rocq is a free interactive theorem prover and proof assistant for developing mathematical proofs, formal specifications, and programs, including proofs that programs satisfy specifications. Its Gallina language supports specification and mathematical work and is based on the Polymorphic, Cumulative Calculus of Inductive Constructions. A relatively small certification kernel machine-checks proofs. Rocq also offers interactive proof methods, decision and semi-decision algorithms, and a tactic language for defining methods. It can extract certified programs to OCaml, Haskell, or Scheme and connect with external computer algebra systems or theorem provers. The Rocq Platform bundles the core prover with libraries and plugins for development and teaching in mathematics, computer science, and related fields. Installation scripts support Windows, macOS, and many Linux distributions; precompiled installers are available for Windows and macOS, but not Linux. Editor options include the VsRocq Visual Studio Code extension, RocqIDE, Proof General, and Coqtail. Rocq is written in OCaml, distributed under the GNU Lesser General Public Licence Version 2.1, and is also available as a Docker image.
For and against
For
- Machine-checks proofs with a relatively small kernel.
- Extracts certified programs to OCaml, Haskell, or Scheme.
- Connects with external computer algebra systems or provers.
- Editor integrations include VsRocq, RocqIDE, and Proof General.
- Free and distributed under LGPL Version 2.1.
Against
- No Rocq Platform binary installer for Linux.
- Linux installation scripts install Rocq and packages from sources.
The verdict
Rocq combines proof checking, proof-development methods, and certified program extraction in a free prover. Linux users should account for the absence of a Platform binary installer.
Who it suits
Rocq suits people developing or teaching mathematical proofs, formal specifications, or verified programs. It may also suit users who want editor integrations or a platform bundling libraries and plugins.
