SWI-Prolog Java Record Converter

This program processes class definitions from a .txt file and generates corresponding .h and .cpp files in a specified directory. The program reads a structured input file containing Java Records, creates a target directory for the output, and writes the generated header and source files. It's designed to streamline the creation of C++ class boilerplate code based on a simple input format.

Steps to run the program

1. Install Prolog Interpreter

• Ensure you have a Prolog interpreter installed, such as SWI-Prolog. If not, you can download it in the following link:

  https://www.swi-prolog.org/download/devel

2. Create an input file

• Make sure that it has a .txt extension and is located in the same directory as the recordConverter.pl file.

3. Add the Java Records you want to turn into C++ classes

• Here are various examples of valid and invalid record structure for the program to convert:

Valid inputs

      public record Person(String name, int age, int id, float height) { } 
      public record Person(String name, int age, Address address) { public static record Address(String street, String city, String zipCode) { } } 

Invalid inputs

          public record Plane(int captainId, int planeId, int passengerAmount, boolean available) { 
              
          }

          public record Person(String name, int ager, Address address) {
            public static record Address(String street, String city, String zipCode) { }
          }     

Important note: as for nested records and in general, as long as the record structure is in a single line, it should not cause any issues

4. Execute the program

• Open the command-line in the directory where 'recordConverter.pl' is located.
• In the command-line type the following command:

swipl -s recordConverter.pl -g recordConverter -t halt

• Then, when prompted, type the name of your input file and click the enter key :)

5. Check the Output

• The program creates a Generated Classes directory. Within this directory, you will find the .h and .cpp files generated for each record described in the input file.
• Each .h and .cpp file will have a name to match that of the original Java Record.
