Brainfuccuccino - brainfuck scripting engine for Java

Brainfuccuccino is a Java scripting engine which allows brainfuck programs to be embedded and run in Java applications. It conforms to the Java Scripting API (JSR 223).

Usage

Using Brainfuccuccino via the Java Scripting API

One key feature of Brainfuccuccino is that it conforms to the Java Scripting API (JSR 223). This allows using the ScriptEngine interface to execute brainfuck programs:

ScriptEngine bfScriptEngine = new ScriptEngineManager().getEngineByName("brainfuccucino");
ScriptContext context = bfScriptEngine.getContext();

// Set up a writer for the brainfuck program to output to.
Writer writer = new StringWriter();
context.setWriter(writer);

// Hello World program from https://esolangs.org/wiki/Brainfuck (CC0 public domain)
bfScriptEngine.eval(
        "++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>" +
        "---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.",
        context
);

// Prints "Hello World!"
System.out.println(writer.toString());

Using Brainfuccuccino directly

Another straightforward option to run brainfuck programs is to call Brainfuccuccino directly.

The following is a cat or a program that echoes back standard input to standard output.

Brainfuccuccino.brew(",[.,]");

Brainfuccuccino.brew attaches System.in and System.out to the input and output (respectively) of the brainfuck program automatically. This allows quick experimentation with brainfuck programs that involve I/O.
