toString() to act as __str__()

[cyraid]

public class MyClass {
  private final String str;
  public MyClass(String str) {
    this.str = str;
  }
  @Override
  public String toString() {
    return str;
  }
}

I would expect calling:

context.getPolyglotBindings().putMember("obj", new MyClass("HI"));
context.eval("python",
  """
  import polyglot
  obj = polyglot.import_value("obj")
  print(obj)
  """);

That it would print "HI" and not <JavaObject[MyClass] at 0xdeadbeef>

Is there a way to make it print it as a string? I've tried using Python's str().

You can always call Java methods using normal Python method calls, so obj.toString() should work. You're right that it would make more sense if the string conversion (__str__ special method) would call toString(), I'll try to change it.

@msimacek Thank you very much! It is a requirement for my company. Do you have an ETA for change? :)

(As we were using Jep before and it worked like that with Jep, but we're evaluating graalpython to be a replacement)

I saw the performance numbers and the sandbox resource limits are what we need! So it looks nice so far!

@msimacek While you're at it, you could you add .equals() when you compare it with something? Like myCustomObj.equals("HI") when my_custom_obj == "HI" as well? (if not that's okay!)

It should get merged today. There should be a nightly build available tomorrow.

As for equals, we'll discuss it internally, it could have other consequences.

@msimacek thank you! That was quick! :) I'm off till Monday so I'll see if I can check it then. :) Hope you have a good weekend!

Sorry, it failed to merge over the weekend due to some CI error, but it should get in soon
