fr.uga.pddl4j.parser (PDDL4J API Documentation)

package fr.uga.pddl4j.parser

This package contains the classes of the PDDL parser. The parser accepts PDDL3.0 language and HDDL extension. See BNF Description of PDDL3.0 implemented in the library more details. Note this code is automatically generated with javacc 4.0.

A simple example of how to use the parser:

 public static void main(String[] args) {

  if (args.length == 2 && args[0].equals("-p")) {
      Parser parser = new Parser();
      try {
          parser.parse(args[1]);
        } catch (FileNotFoundException e) {
          System.out.println(e.getMessage());
        }
      if (!parser.getErrorManager().isEmpty()) {
          parser.getErrorManager().printAll();
      }
  } else if (args.length == 4 && args[0].equals("-o") && args[2].equals("-f")) {
    Parser parser = new Parser();
    try {
          parser.parse(args[1], args[3]);
        } catch (FileNotFoundException e) {
          System.out.println(e.getMessage());
        }
      if (!parser.getErrorManager().isEmpty()) {
          parser.mgr.printAll();
        }
    } else {
      System.out.println("\nusage of parser:\n");
      System.out.println("OPTIONS   DESCRIPTIONS\n");
      System.out.println("-p <str>    path for operator and fact file");
      System.out.println("-o <str>    operator file name");
      System.out.println("-f <str>    fact file name\n");
    }
 }
