 After you've built the project, you may want to set up an excutable file on your path to make it easy to launch your build of jython. This file will need to:
 *Set the python home property to the `dist` directory of your build (otherwise, you'll get import errors on the standard lib stuff).
 *Execute the `jython.jar` in the `dist` produced by the build.
Here's a batch file that runs the built jython.jar (for windows): [[Anchor(sampleBatch)]]		  As part of building the project, Jython will generate an executable script, `dist/bin/jython`, to make it easy to launch your build of Jython. This works if you're on a Unix-like platform (including Mac OS X and Cygwin).

If you're using Windows without Cygwin, here's a batch file that runs the built `jython.jar`:

On Unix you can use a shell script: {{{
#!/bin/sh

exec java -Dpython.home=<path>/dist/ -jar <path>/dist/jython.jar $*

This is an introduction to developing Jython, just to get someone started. It doesn't cover the source code in any depth or discuss the design behind Jython. It's purely aimed at getting a development environment set up. It's definitely not complete so feel free to make it better!

SVN

Ant

  • http://ant.apache.org/ A Java-based build tool.

  • Eclipse users, see [wiki:/EclipseNotes Eclipse ANT notes]

  • Download the latest version and install so Ant's bin directory is somewhere in your path.

  • The build.xml is the file containing the compiler directives

  • After getting Ant set up, run ant in your Jython checkout directory. That should produce dist/jython.jar if everything is setup correctly.

Tests

  • As part of building the project, Jython will generate an executable script, dist/bin/jython, to make it easy to launch your build of Jython. This works if you're on a Unix-like platform (including Mac OS X and Cygwin).

If you're using Windows without Cygwin, here's a batch file that runs the built jython.jar: Anchor(sampleBatch) 

:: jytip.bat
@echo off
set ARGS=

:: concatenate all the command line args into one
:loop
if [%1] == [] goto end
        set ARGS=%ARGS% %1
        shift
        goto loop
:end

:: this is mine...
:: java -Dpython.home=C:\\workspace\\JythonTip\\jython\\dist -jar 
::<cont> c:\workspace\JythonTip\jython\dist\jython.jar %ARGS%
:: fill in <placeholders> below:
java -Dpython.home=<path to dist directory>\\dist -jar <path to dist directory>\dist\jython.jar %ARGS%

Now you're ready to run tests...

  • There are a couple different places to find test cases

    • Jython's dist/Lib/test (populated by the build process)

    • Jython's bugtests subdirectory (included with the development sources)

  • Run a particular test, or you can run the whole Python test suite with ant regrtest.

See TestingJython for some more details.

Directory layout Note the following describes the current trunk/jython. If you are working from an older tag, src doesn't exist and src/com and src/org are moved up a level.

  • src/org : top level package for python
  • src/com : zxJDBC related sources

  • src/templates : java source generator & related templates, used to update portions of java classes elsewhere in the source tree

  • Demo : demo sources for the website and such

  • Doc : the website documentation(see /WebsiteBuilderSetup to build the http://jython.org website)

  • Lib : the python source files for Jython standard library implementations
  • Lib/test : test cases
  • Misc : random scripts which are not all used; some generate source
  • Tools : JythonC and Freeze

  • CPythonLib : Lib directory from the corresponding version of cpython, via svn:externals

  • bugtests : additional test cases covering bug reports
