The Jython Project. UserGuide - JythonWiki. Intro For a look at the Jython internal API see the generated JavaDoc documentation. General Python Documentation Since Jython is an implementation of Python for the JVM, most of the standard Python documentation applies. Look in the following places for general information: The Python Tutorial (start here)The Python Library Reference. Most of these modules are available, although some coded in C for CPython must be re-implemented in Java for Jython. In general, those that are implemented follow the library reference as closely as possible.The Python Language Reference (for language lawyers). Invoking the Jython Interpreter Jython is invoked using the "jython" script, a short script that invokes your local JVM, sets the Java property install.path to an appropriate value, and then runs the Java classfile org.python.util.jython. jython [options] [-c cmd | -m mod | file | -] [arg] ... options -i: Inspect interactively after running script; force prompts even if stdin is not a terminal.
-jar jar args. JyNI – Jython Native Interface — JyNI Project Homepage. An Introduction to Jython. Jython is a version of Python written in Java and designed to run under the JVM. Because of this, it integrates closely with Java, and allows Jython programs access to all of the Java libraries. There are several reasons that Java programmers might be interested in learning Jython: It provides an alternative to Javascript for interacting with Java, and is in many ways more powerful than Javascript. Most would also agree it is much easier to use than Javascript.It is very easy to embed the Jython interpretor as a scripting or application control language in your Java applications.It allows more rapid prototyping, and/or "proof of concept" applications than is possible in Java.
With this very short and brief introduction, lets jump right into some code. In the spirit of programming books, we will start with the very simple "Hello World! " program as it would be written in Jython: print "Hello, world! " file = open("Test.txt", "r") for line in file.readlines(): print line file.close() self. Distributing my python scripts as jars with jython? JythonFaq/DistributingJythonScripts - JythonWiki. Return to JythonFaq How can others use scripts/applications I've developed? Initial creation date: Aug 2007 last updated: Aug 6, 2009 Using Maven The easiest way to distribute a standalone jar is by using the jython compilation maven plugin.
It allows you to deploy a standalone project that includes jython with libraries. For demonstration of this plugin, see the demo project and its source code. Launch a python console -- look at AbstractInitJython and InitJython on how to launch a python/jython console, how to execute python code snippets, and how to run a python script. include python libraries -- the plugin also downloads and bundles python libraries (using easy_install) in the package phase, and adds them to the jar. For testing python / jython code, the python test maven plugin allows you to run your python tests alongside the normal junit tests. The sourceforge umbrella project is Manually Requirements What I did is install Jython twice.
For example: Embedding Jython in Java Applications. Python, PyTables, Java - tying all together. JyNI – Jython Native Interface — JyNI Project Homepage. Jython / Mailing Lists. ReplaceJythonc - JythonWiki. Jythonc doesn't handle generators and is difficult to debug and improve. The current thinking is to add capabilites to jython itself to generate bytecode from py files and run those statically compiled items rather than jythonc's approach of making Java classes that work like the base Python code. The current thinking runs as follows: Turn Python classes into Java classes without a Java interface or class using function annotations to specify the static Java type information statically compile proxy classes for Python classes that extend Java classes remove code from core that is only there to support jythonc The annotation goes on any method in a Python class that needs to be visible from Java and __init__ for the constructor.
Given the following annotated Python class class Simple(object): @java def __init__(self): @java(String, String) def firstWord(self, param): return param.split(' ')[0] Java bytecode corresponding to is generated. Jimbaker/clamped. Easy Applets with Jython.
