Exports lambda expressions in the Babel format.
Exports lambda expressions in the Babel format. You probably do not want to use this class, use one of expression.toString, .toSigRelativeString, or .toAsciiString instead. These are all implemented using this class.
This exporter is implemented using the pretty-printing library included in Kiama.
A signature for the Babel parser.
A signature for the Babel parser. This class decides whether a free identifier is a variable or a constant.
A signature based on a map: The identifiers for which the map is defined are constants, the rest are variables.
A signature based on a map: The identifiers for which the map is defined are constants, the rest are variables.
A map from strings to types.
Class with two possible cases, one for variables and one for constants.
Contains various methods for generating signatures.
Intermediate representation for expressions parsed by Babel.
Intermediate representation for expressions parsed by Babel.
This representation is intended to be as simple as possible, all higher-level constructs (such as <-> or ∀) are already desugared into simply-typed lambda terms.
It differs from the "real" lambda calculus in at.logic.gapt.expr in three major ways:
