beakerx.showProgressUpdate from Scala

[pschatzmann]

I am not able to call beakerx.showProgressUpdate() from Scala:

• beakerx.showProgressUpdate("", 1) gives the error: :99: error: the result type of an implicit conversion must be more specific than AnyRef beakerx.showProgressUpdate("", 1)
• beakerx.showProgressUpdate("", new java.lang.Integer(1)) gives the error: java.lang.NoSuchMethodException: com.twosigma.beakerx.NamespaceClient.showProgressUpdate(java.lang.String, java.lang.Integer)

I think it would help if you change the method definition from public void showProgressUpdate(String message, int progress) to public void showProgressUpdate(String message, Integer progress) in com.twosigma.beakerx.NamespaceClient

The beakerx object currently does everything through the dynamic interface, and that's the real problem. A quick workaround would be to use _beakerx. If beakerx should support the BeakerXClient interface, then it needs to implement that interface.

[pschatzmann]

You are right! In Groovy the beakerx variable is of the class com.twosigma.beakerx.NamespaceClient and this seems to be different in Scala: _beakerx.showProgressUpdate("",50) is working as expected!

Thanks for the clarification...

I think it's confusing that the beakerx object in Groovy has both static behavior and dynamic fields, while in Scala some of the static behavior happens to work but some doesn't. I mentioned in an earlier discussion that I don't think the dynamicApply support in the beakerx object is useful.

Either _beakerx should be documented, or beakerx should implement the static behavior. I think the latter would be more consistent with other kernels.

I think the following approach should work consistently across the different kernels:

var client = NamespaceClient.getBeakerX()
client.showProgressUpdate("", progress )
