Enhancement Proposals

Roadmap

Testing Phase (available soon)

• save/restore current proof
• add cut rule

Near Future

• formula naming through (possibly recursive) equations (with click on name to unfold a definition inside a proof)
• explicit exchange rule (with colored backgrounds to follow instances of formulas) (issue #11)

Other directions

• two-sided sequent calculus
• intuitionistic linear logic
• other linear logic variants (ELL, SLL, LLL, etc.)
• quantifiers (issue #16)
• contexts as first-class objects (issue #13)
• cyclic linear logic (exchange restricted to circular shifts, requires to modify the definition of dual of a formula)
• additional tool for proof transformations (cut elimination, axiom expansion, reversing, focusing, substitution, etc.) (issue #12)
• back edges for regular proofs
• fixed-point connectives in formulas
• mix rules (note mix₂ can be faithfully simulated by adding ?(⊥⊗⊥) in the context, and similarly for mix₀ with ?1)
• export to proof-nets
