dynjs - ECMAScript Runtime for the JVM

Bug Reports

We're using GitHub Issues. Please let us know what issues you find!

Setting up environment

Getting JDK7

OSX can get information on installing at the java site.

Download and install it to your user (not to the entire machine) and before running mvn install run (or use Java7 as default compiler):

	export JAVA_HOME=$(/usr/libexec/java_home -v 1.7)

Getting started

Building from sources

git clone https://github.com/dynjs/dynjs.git && cd dynjs
mvn install -s support/settings.xml

Download

Alternatively download the latest dynjs dist zip package from our CI job, then unpack it somewhere. As a convenience, you can symlink bin/dynjs to some directory enlisted on your $PATH, it should work fine!

Running

Run ./bin/dynjs --console for the REPL and try the snippet below:

var x = 1 + 1;
print(x);

For more options, run ./dynjs --help.

dynjs's Issues

Make Java objects have Object.keys and such

Regex fails with some whacky regexes

This regex taken from an express.js dependency causes a stack to be generated.

var ipv6Part = "(?:[0-9a-f]+::?)+";
var regex = new RegExp("^((?:" + ipv6Part + ")|(?:::)(?:" + ipv6Part + ")?)");

Stack:

Support v8 Custom Error API

Needed for nodyn. See nodyn/nodyn#81 and https://code.google.com/p/v8/wiki/JavaScriptStackTraceApi

This should be configurable in a similar fashion to how we support commonjs.

A TypeError exception is thrown when opal.js file is imported

I am trying to use DynJs to integrate asciidoctor.js to Java. Asciidoctor.js has a dependency to opal.js library. Opal.js used is located at https://github.com/asciidoctor/asciidoctor.js/blob/master/dist/opal.js.

Those files works when they are executed from a browser.

The java code used is:

Config config = new Config();
DynJS dynjs = new DynJS(config);

final Runner runner = dynjs.newRunner();
runner.withSource(new File("src/test/java/sc/opal.js")).execute();

Maybe the problem is that opal is using a feature not supported by DynJs.

Thank you so much for your support.

Support for Java byte arrays in Javascript

Moving http://jira.codehaus.org/browse/DYNJS-107 to GH Issues

bob mcwhirter added a comment - 28/May/13 1:11 PM
Not currently possible, but a useful addition.

Volker Hahn added a comment - 30/May/13 5:42 AM
@bob: Is there an alternative way to get a Java Byte array?

Lance Ball added a comment - 06/Jun/13 10:23 AM - edited
As a stopgap, you could try having a Java class with a method like, createByteArray(). E.g. ByteArrayFactory.java

package me.developer.factories;

public class ByteArrayFactory {
    public static Byte[] newByteArray(int length) {
        return new Byte[length];
    }
}

And then in javascript

var javaBytes = me.developer.factories.ByteArrayFactory.newByteArray( 10 );

MethodGenerator fails method calls with primitive types on Java objects

When a Java interface or abstract class contains a method with primitive type parameters, JS implementations of the class fail to construct. For example in Java:

package org.foo;
public interface Foobar {
    public void doSomething(boolean now);
}

And then in JS:

var impl = {
  doSomething: function(now) {
    console.log(now);
  }
}

var foo = new Foobar( impl );

Fails with something akin to:

org.dynjs.exception.ThrowException: java.lang.VerifyError: Bad local variable type

dynjs -v sometimes outputs 'undefined' as version

disable shading during normal runs

Since we've went the multi-jar route, we can cut a good chunk of build time by only shading during releases

someUndefinedObj.property throws TypeError, possibly related to #95

I'm using the org.dynjs:dynjs:0.3.0-SNAPSHOT artifact (included in io.nodyn:nodyn:0.1.1-SNAPSHOT from https://oss.sonatype.org/content/repositories/snapshots), and the statement if(someUndefinedObj.property) { } throws a TypeError, whereas the expected behavior (for me) is that the undefinedObj.property evaluates to false. Maybe related to issue #95. Stack trace:

Fails to call java.lang.String.startsWith

I'm using jasmine-jvm to write some jasmine tests.

Dyn.js is silently failing in the following code:

    var path = new java.lang.String('/~/my/path');
    if (path.startsWith('/~')) { // Fails here
        this.handleRegistration(request);
    }

This was tested with dyn.js 0.2.1 and 0.2.2.

allow to add entries to the classpath programatically

dynjs.classpath.push(), as discussed on #92

Command line REPL does not set runtime classpath with DYNJS_OPTS

https://gist.github.com/lance/c2c6bd79923684373ef8

This is the root cause for problems seen with ActiveMQConnectionFactory as reported on the mailing list. This issue supercedes and closes #91

InvokeDynamicInterpretingVisitor should generate more useful error messages

Moving http://jira.codehaus.org/browse/DYNJS-119 to GH Issues

The error message generated when calling a non-existent method on a Java object is not terribly useful. InvokeDynmaicInterpretingVisitor#visit should generate more useful error messages. Specifically, the method that is "not callable" should be a part of the error message, and the stack trace should be minimized.

Here's how it looks now:

Top-level global execution context needs "arguments" equivalent to argv

Moving http://jira.codehaus.org/browse/DYNJS-111 to GH Issues

While this may not be in the spec, both node.js and rhino initialize an arguments Object for the top-level execution context. When executed from the command line, the top javascript object in both environments will have the command line arguments (excepting the JS filename) included in the arguments object.

implementing an abstract class causes a ArrayIndexOutOfBoundsException

Hi,

I'm trying to create a jetty server in javascript. As template I have used the java example from http://www.eclipse.org/jetty/documentation/current/embedding-jetty.html.

This is my javascript which is causing the exception.

...
handler = new org.eclipse.jetty.server.handler.AbstractHandler( {
    handle: function(target, baseRequest, request, response) {
    }
});
...

I'm using dynjs 0.2.0.

Here is the stracktrace.

Add support for missing CallSite functions

In addition to the fact that we expose Java StackElements instead of Javascript CallSite instances in a stack trace, we also need to add support for a half dozen methods defined by the V8 stack trace API. See StackElement.java. The following methods are not implemented:

public int getColumnNumber() {
    return 0;
}

public StackElement getEvalOrigin() {
    return null;
}

public boolean isTopLevel() {
    return false;
}

public boolean isEval() {
    return false;
}

public boolean isNative() {
    return false;
}

public boolean isConstructor() {
    return false;
}

Allow java.lang.Throwable to respond to 'stack'

This should work for both .js and .java errors that are thrown:

try {
  somethingThatThrowsJavaExceptions();
} catch (err) {
  console.log( err.stack );
}

Implement an IR for better optimizing code generation

Moving http://jira.codehaus.org/browse/DYNJS-35 to GH Issues

We need to implement an IR (code flow graph representation) for having better optimizable code generation.

the pipeline will look like this: code -> parser -> AST -> IR -> bytecode

Here's a cool graph library we might use for it

Implement Object.prototype.proto

Unable to Use Types in the javax.* Packages

Any attempts to use types in the javax.* packages generates a "ReferenceError: unable to reference: javax" error.

Note that you need to work around #92 to verify this issue.

Line numbers in some complex stack traces are incorrect

thread safety

Is there any proper way to compile JS function once and execute it in multiple threads?
I'm trying to catch function to variable - something like

        fn = (JSFunction) dynJS.evaluate(compilerScript,"\n;\n" +
                "(function(){return function(coffeeScriptSource, bare){return CoffeeScript.compile(coffeeScriptSource, {bare: !!bare});};})();" );

but invoking it in multiple threads produce exceptions

Null result from java function call is transformed into undefined

When calling a function from a Java object that returns "null", that null value somehow becomes "undefined" in JavaScript. The following test passes when using Nashorn, but fails with DynJS (0.3.0-SNAPSHOT)

public class TestClass {
    public Object thing() {
        return null;
    }
};

@Test
public void testReturnNullFromJava() throws ScriptException, NoSuchMethodException {
    ScriptEngine engine = new ScriptEngineManager().getEngineByName("dynjs");
    engine.eval("var doSomething = function(o) { return o.thing() === null; }");
    TestCase.assertTrue((Boolean) ((Invocable) engine).invokeFunction("doSomething", new TestClass()));
}

Parser fails with properties named "false"

Moving http://jira.codehaus.org/browse/DYNJS-121 to GH Issues.

If an object returned from a function has a property named "false" the parser fails with a syntax error. This only happens on objects returned from functions. See this gist for a simplified example of what works and what does not work.

Multi line regular expressions do not split on line feed as it seems they should

Here is a simple example.

function println(msg) {
  java.lang.System.out.println(msg);
}

var multiline = "FOO=bar\nFOOBAR=boom\n";
var regex = new RegExp(/([\w+]+)\s*\=\s*(.*)/gmi);
var lines = regex.exec(multiline);
var print = (typeof console !== 'undefined') ? console.log : println;


for (var i=0;i<lines.length;i++) {
  print(">> LINE " + lines[i]);
  print(".....");
}

Running this under nashorn produces the following:

$ jrunscript regexp.js
>> LINE FOO=bar
.....
>> LINE FOO
.....
>> LINE bar
.....

Running under node produces the following:

$ node regexp.js
>> LINE FOO=bar
.....
>> LINE FOO
.....
>> LINE bar
.....

Running under dynjs produces the following:

$ ./bin/dynjs regexp.js                                                                                                                   ✭ ✱ ◼

Support runtime binding of Java object methods to JS Objects

Supported by Nashorn - this would be a nice addition to dynjs.

var obj = {};
Object.bindProperties(obj, myJavaObject);
print(obj.foo); // calls myJavaObject.getFoo() bean getter

From the nashorn-dev mailing list, "The above 'binds' bean-style properties of your Java object to the script object "obj". The script object could have usual proto and so on. This flexible option allows your script object to behave as normal script object -- but some properties being implemented in Java".
