[Jython-dev] Re: [Jython-users] future direction of Jython

[Kent J. <ke...@td...>]

Brian,

I would like to see Jython work better with Java. Two areas that keep coming up for me are the need to implement interfaces to see Jython methods from Java, and the need to write special code to instantiate a Jython class from Java. I know that jythonc addresses these problems but I have never been able to get it to work on a real project. I would like to see support for @sig lines in the interpreter.

A minor wart is the difference in the way Java and Jython classes are imported. Maybe Java imports should use Jython syntax so you don't have to think about what you are importing.

In other words, if I want to use the class example.Foo defined in example/Foo.py, I write
from example.Foo import Foo

If Foo is defined in example/Foo.java, I write
from example import Foo

I did some hacking of the runtime to support launching a Jython program using Java Web Start. I would like to see some version of those changes included in the standard distribution.

WRT compatibility with CPython, I think it is important for Jython and CPython to match in the areas where they overlap. I think the Jython language itself should have the same syntax and semantics as a release version of CPython. To the extent they have the same libraries, the function of the libraries should be the same. I don't think it is so important to keep current with CPython though some movement in that direction would be nice, i.e. get to CPython 2.2.
