    Package structure

    The leo package contains two sub-packages as follows:

    Usage (in short)

    The leo.modules.input.TPTPParser offers several parsing methods:

    Exemplary use case 

    import leo.modules.input.{TPTPParser => Parser}
import TPTPParser.TPTPParseException
import leo.datastructures.TPTP.THF

try {
 val result = Parser.problem(io.Source.fromFile("/path/to/file"))
 println(s"Parsed ${result.formulas.size} formulae and ${result.includes.size} include statements.")
 // ...
 val annotatedFormula = Parser.annotatedTHF("thf(f, axiom, ![X:$i]: (p @ X)).")
 println(s"${annotatedFormula.name} is an ${annotatedFormula.role}.")
 // ...
 val formula = Parser.thf("![X:$i]: (p @ X)")
 formula match {
   case THF.FunctionTerm(f, args) => // ...
   case THF.QuantifiedFormula(quantifier, variableList, body) => // ...
   case THF.Variable(name) => // ...
   case THF.UnaryFormula(connective, body) => // ...
   case THF.BinaryFormula(connective, left, right) => // ...
   case THF.Tuple(elements) => // ...
   case THF.ConditionalTerm(condition, thn, els) => // ...
   case THF.LetTerm(typing, binding, body) => // ...

   case THF.ConnectiveTerm(conn) => // ...
   case THF.DistinctObject(name) => // ...
   case THF.NumberTerm(value) => // ...

object TPTP

Collection of TPTP-related data types that are returned by the leo.modules.input.TPTPParser. An overview:

See TPTP.THF, TPTP.TFF, TPTP.FOF, TPTP.TCF, TPTP.CNF for more information on the representation of "plain" THF, TFF, FOF, TCF and CNF formulas, respectively.

All classes have a function called pretty that will output the TPTP-compliant representation of the respective structure. It should hold that parse(x.pretty) = x where parse is the hypothetical parsing function for that structure.

  6. final def convertStringToAtomicWord(word: String): String

    Converts a string to a TPTP atomic word.

    Converts a string to a TPTP atomic word.

    A TPTP atomic word is either a TPTP lower word or a single quoted string. If word is a TPTP lower word (i.e., starting with a lower case letter, followed by alphanumeric letters or underscore) it is returned unchanged. Otherwise (e.g., if it contains special characters), it is escaped to a single quoted string (and characters ' and \ are escaped to \' and \\, respectively, if any).

    Note

    Important: The Dollarworld $true and the atomic word '$true' are not the same! The input word = "$true" will be escaped to "'$true'". If you wish to use the input as dollar word or dollar-dollar word, don't use this function!

  7. final def convertStringToName(name: String): String

    Transform the input string into a TPTP name.

    Transform the input string into a TPTP name. A TPTP name is either an integer, or an atomic word. If name is a TPTP integer or a TPTP lower word, it is returned unchanged. Otherwise (e.g., if it contains special characters), it is converted to a single quoted string (and characters ' and \ are escaped to \' and \\, respectively, if any).

    Escapes an TPTP atomic word (characters ' and \ are escaped to \' and \\, respectively, if any, not including outer quotes if any).

    Escapes an TPTP atomic word (characters ' and \ are escaped to \' and \\, respectively, if any, not including outer quotes if any).

    Assumes: word is an TPTP atomic world (either single quoted or lower word).

    Note

    This will give strange results for inputs that are not atomic words (e.g., TPTP dollar words).
