jython3's Introduction

This is not where Jython 3 is developing.

The latest released version of Jython remains 2.7.x (see Jython for that).

This doesn't mean that there isn't any progress on a Jython 3. A lot of exploration has taken place away from the official repository, in order not to pollute it with false starts and dead-ends.

Since the beginning of 2021, Jython 3 exploratory work reached a form that merited porting from the experiment to the main of the official repo. Risky design concepts still begin life in the exploratory environment, then arrive as a PR to the official main branch. Please watch the jython-dev mailing list for developements, or the main branch (not master) of the official Jython repo.

If this is not the real thing, what is it?

This repo represents an attempt made in 2016 to implement a Jython 3.5, that is, with language and runtime compatibility with CPython 3.5, along with continued substantial support of the Python ecosystem. It is a sandbox for that venture. This code having branched from an early 2.7, the architecture is that of Jython 2, without taking advantage of the (then fairly new) dynamic language support. It has not been updated with subsequent bug-fixes made on Jython 2.7, and there is no plan to to do so.

Please see ACKNOWLEDGMENTS for details about Jython's copyright, license, contributors, and mailing lists; and NEWS for detailed release notes, including bugs fixed, backwards breaking changes, and new features.

site.py is python 2 ?

C-style octal literal was removed in Python 3

thus 0o123 is fine, but 0123 should raise syntax error now.

You have seen that the official website of jython said it would launch version 3.8. Is this project still under maintenance? I pulled your master branch and found that some classes were missing. I look forward to your reply

Jython 3 on GraalVM & Truffle?

Zippy (https://github.com/securesystemslab/zippy) has Python 3 implemented on
Truffle framework (https://github.com/graalvm/truffle).

JRuby has Truffle with Sulong to run C extension
(http://chrisseaton.com/rubytruffle/llvm-cauldron-16/llvm-cauldron-sulong.pdf)

Is there any discussion on Jython following such path?

Wrong column number when parsing single character parameter

I'm parsing the following file:

import tensorflow as tf

def add(a, b):
  return a + b


c = add(tf.ones([1, 2]), tf.ones([2, 2]))  #  [[2., 2.], [2., 2.]]

When we get to parameter a, I see the CommonToken representing a as follows:

[@12,33:33='a',<63>,3:8]

Particularly, charPositionInLine for a is 8, but it should be 9. Also, there's one character, so we should see 33:34 as the start and end column.

This can support python3.5 third-party libraries? For example: numpy, if so, how to use

As the title shows

Travis ?

In jython3 have https://github.com/jython/jython3/blob/master/.travis.yml , but jython3 not enable travis.

zippy (python3 on jvm) - join forces

https://github.com/securesystemslab/zippy
zippy is also an effort to implement python 3.x on top of JVM.

May be, you people can formally invite them to join your team too
So that this port can be completed

Missing AST node for `Bytes`

In Python 3, b'' results in AST tree Bytes(s=b'')

when are jython3 download?

The last update was three years ago. Does that mean that the update has stopped？

java.lang.ExceptionInInitializerError: java.lang.ExceptionInInitializerError

Something is happening at import command that is generating this error.
As you can see at code, I am just importing but not using the imported class.

Added: I just noticed that the same error occurs when I try import Control directly.
Appears that the error are in creation of this class and classes that have Control as parent class, for any reason. By the other side, try to import classes that have Pane as parent works, even having Pane Control as his parent class. I don't know if this information helps.

Thanks for your help.

Dear all old buddy , where can i find the most advanced and stable version jython?

Remove old except syntax

the except Foo, bar should be removed.

Jython is still in development ?

I found a mercurial repository https://hg.python.org/jython/
The git repository is not updated?

True, False, None should be keywords

Merge PyString into PyUnicode

The resulting class could be called PyUnicode, as in CPython.

build explanation

Hi, it's not clear from just examining the files in the repo how to build the code. There is a build.xml, so ant? Then there is also a maven directory, but with no fully formed pom in it. Can you clarify how to go about building the code and run the tests?

Merge PyInteger into PyLong

The resulting class should probably be called PyLong as in CPython API; this would also aid in porting libraries to Jython 3.

How to install?

I clone this repository, but i don't understand how to install Jython 3 on my PC

If I try the same in python it works fine but running through jython give me the above error, can you please help me out what is the problem?

Project pulse is flatline.

I was looking for a solution to using mixed python and java, but required python 3 for my company project. When I started work on the project last spring, this project looked like a long road so I decided to use jpype. I figured that this project would catch up eventually. But since then it appears this project has completely stalled.

Is there a road map or a task list with things that contributors can do to get this project back to moving? Or has it died completely? What level of push is required to get a beta for python3?
