An extensional type theory proof management system.
The dialect of intuitionistic type theory used is also referred to as computational type theory.
The PRL part of the name evidently stands for “Proof Refinement Logic”.
MetaPRL: A logical framework implementation that includes (an old version of) Nuprl’s logic as a theory, and focuses on an efficient, modular tactic engine for proof automation.
RedPRL: An experimental proof assistant for a cubical variant of computational type theory.
Prototype CompLF: A tentative design for a modern, minimalistic variant of Nuprl’s logic, with an emphasis on internally reflecting the semantic judgments.
based on plain type theory/set theory:
based on dependent type theory/homotopy type theory:
based on cubical type theory:
