Executor Examples

Executing a file

var fs = require('fs');
var basic = require('basic');

function runFile(file, done) {
	fs.readFile(file, { encoding: 'utf8' }, function(err, data) {
		if (err) return done(err);

		var ast = basic.parser.parse(data);
		basic.executor.execute(ast, done);
	});
}

A simple REPL (read-eval-print-loop)

var basic = require('basic');
var rl = basic.IOInterface.getDefault();

var context = new ExecutionContext();
var manager = new BlockManager();
var ast = new AbstractSyntaxTree([], {}, manager);

function run() {
	rl.readln(function(cmd) {
		var line = basic.parser.parseLine(cmd, ast.root.length, ast.labels, false, ast.manager);
		ast.root.push(line);
		ast.manager.parse(ast);
		context.options.cursorStart++;
		ast.execute(context, run);
	});
}
