Description
Implementation of a theorem prover for intuitionistic propositional logic using G4ip in Haskell.
Fork of cacay/G4ip.
G4ip rules
Improvements over the original code
- proof trees are now constructing explicitly
- added proposition parser
- added exporting of the proof tree to LaTeX
File Structure
- G4ip/Proposition.hs -- Definition of propositions and some syntactic sugar
- G4ip/Prover.hs -- The actual theorem prover
- G4ip/Parser.hs -- Parser for propositions
- G4ip/LaTeXExporter.hs -- Exporter for proofs
Usage
g4ip-prover [OPTIONS] PROPOSITION
g4ip-prover [OPTIONS]
If the proposition was not specified, the user will be prompted to enter it interactively.

Default value: static/proof-header.txt
--proof-footer <file> Template footer file for proof.
Default value: static/proof-footer.txt
--context-header <file> Template header file for context.
Default value: static/context-header.txt
--context-footer <file> Template footer file for context.
