Official Support for Jython in Visual Studio
Python Tools for Visual Studio, which has its first production release today, now supports all four major Python interpreters, CPython, IronPython, Jython, and PyPy. It is available with the free Visual Studio Integrated Shell or as a plugin for Visual Studio Professional. Somasegar writes,
One of the most important aspects of Python development is interactivity, and PTVS integrates a Python REPL directly into Visual Studio. The REPL window will work for all of the aforementioned Python variants and supports auto-completion, syntax highlighting, and visualizations. For users accustomed to the enhanced REPL provided by IPython, PTVS supports IPython 0.11. For developers using IronPython, the REPL supports Sho.
Python Tools for Visual Studio is released under the Apache 2.0 license.
