Propositional.hs

-- | The "Data.Logic.Propositional" module provides a set of functions for
-- parsing, manipulating and generating truth tables for expressions in
-- classical propositional logic.
--
-- The core of the API is the 'Expr' data type, which has constructors for all
-- the usual expression forms: variables, standing for atomic propositions;
-- negation, the only unary connective; and the binary connectives of
-- conjunction, disjunction, material implication and logical equivalence.
