Shows how you can build a smaller js binary to only parse (and print) some ES6 code.

compile.sh

traceur --out out.js parser.js

# Traceur does not strip dead code. Use Uglify2.
uglifyjs src/runtime/runtime.js out.js -cm -o out.min.js

interpret.sh

traceur parser.js

parser.js

import {Parser} from './src/syntax/Parser.js';
import {SourceFile} from './src/syntax/SourceFile.js';
import {ErrorReporter} from './src/util/ErrorReporter.js';
import {TreeWriter} from './src/outputgeneration/TreeWriter.js';

var file = new SourceFile('name', '`abc`');
var reporter = new ErrorReporter();
var parser = new Parser(reporter, file);

var tree = parser.parseProgram();

console.log(TreeWriter.write(tree));
