While language simulator

Web application for developing and testing WHILE/LOOP programs.

Developed by Simon Meusel and contributors at the research group Knowledge-Based Systems.

Grammar files and parser

• The WHILE/LOOP language grammar can be found at src/core/parser/nearley/whileGrammar.ne and src/core/parser/nearley/tokens.ts
• To programmatically parse, analyse and run a WHILE/LOOP program, use the src/core module:

const parser = new NearleyParser();

const programText = 'LOOP x1 DO x0 := x0 + x2 END';
const program = new Program(parser.parseProgramText(programText));

const generator = program.start();

// Simulate the program step by step
for (const configuration of generator) {
    console.log(configuration);
}
