License

---------

kPascal is distributed until the GPL v3. For more information please see the [GPL](http://www.gnu.org/licenses/gpl.txt).

The grammar

---------

kPascal uses [Antlr](http://www.antlr.org/).  The Pascal grammar is [here](https://github.com/antlr/grammars-v4/blob/master/pascal/pascal.g4)

Using kPascal in code

---------

Using a file:

````

FileInputStream fileInputStream = new FileInputStream("myprogram.pas");

Interpreter interpreter = new Interpreter();

interpreter.run(fileInputStream);

````

Using a string:

````

String myProgram = "program HelloWorld; begin writeln('hello'); end."

ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(myProgram.getBytes());

Interpreter interpreter = new Interpreter();

interpreter.run(byteArrayInputStream);

````

Custom input and output streams

---------

kPascal uses `System.in` and `System.out` as the console by default. However, it is possible to provide your own input and output IO streams.

````

public void runPascalProgram(InputStream pascalInputStream, InputStream consoleIn, PrintStream consoleOut){

   Interpreter interpreter = new Interpreter(consoleIn, consoleOut);

   interpreter.run(programInputStream);

}

````

Using kPascal from the command line

---------

````

java -jar kpascal.jar --file=myprogram.pas

````
