@hackage logic-TPTP0.4.4.0

Import, export etc. for TPTP, a syntax for first-order logic

For information about the TPTP format, see http://www.cs.miami.edu/~tptp/.

Components:

  • Parser (parse)

  • Exporter (toTPTP)

  • Pretty-printer (pretty)

  • QuickCheck instances (generation of random formulae)

  • diff : Get a "formula" which represents the differences between two given formulae (equal subexpressions are truncated; so are the subexpressions of subexpressions whose heads already differ)

Tests passed:

  • For randomly generated formulae, parse . toTPTP == id

  • For all files in the TPTP (v 5.2.0) distribution's Problems subtree which don't match the regex "^(thf|tff)(", parse . toTPTP . parse == parse

Not yet implemented: The new thf and tff formula types.
