Domain-specific

• Sequent
  • Proof assistants and type theory. Interactive systems display local hypotheses and a target in a sequent-shaped goal state, even when the kernel's underlying formalism is dependent type theory rather than Gentzen's `LK`.

    This sourceOfficial documentation for context-and-target goal displays, tactic-driven proof-state transformation, and proof terms.
