scala-tptp-parser v1.4

scala-tptp-parser is a Scala library (for Scala 2.13.x) for parsing the input languages of the TPTP infrastructure.

The package contains a data structure for the abstract syntax tree (AST) of the parsed input as well as the parser for the different language of the TPTP, see http://tptp.org for details. In particular, the parser supports:

• THF (TH0/TH1): Monomorphic and polymorphic higher-order logic,
• TFF (TF0/TF1): Monomorphic and polymorphic typed first-order logic, including extended TFF (TFX),
• FOF: Untyped first-order logic,
• TCF: Typed clause-normal form,
• CNF: (Untyped) clause-normal form, and
• TPI: TPTP Process Instruction language.

The parser is based on v7.4.0.3 of the TPTP syntax BNF (http://tptp.org/TPTP/SyntaxBNF.html).

Version 1.4 of the scala-tptp-parser library.

Updates:

• Bumped Scala version to 2.13.6
• Support for TFX (see http://tptp.org/TPTP/Proposals/TFXTHX.html)
• Support for TPTP non-classical format, partly experimental (see http://tptp.org/NonClassicalLogic/)
• Fixed a few minor bugs
