NAME

       jython - Python seamlessly integrated with Java

SYNOPSIS

       jython [ -i ] [ -S ] [ -v ] [ -Dproperty=value ... ] [ -Wargument ]
              [ -Ecodec ] [ -Qargument ]
              [ -jar jar | -c cmd | file | - ] [ script-args ]

       jython [ --help | --version ]

DESCRIPTION

Jython is an implementation of the high-level, dynamic, object-oriented language Python seamlessly
integrated with the Java platform. The predecessor to Jython, JPython, is certified as 100% Pure Java.

Jython is complementary to Java and is especially suited for the following tasks:

Embedded scripting:
Java programmers can add the Jython libraries to their system to allow end users to write simple
or complicated scripts that add functionality to the application.

Interactive experimentation:
Jython provides an interactive interpreter that can be used to interact with Java packages or with
running Java applications. This allows programmers to experiment with and debug any Java system
using Jython.

Rapid application development:
Python programs are typically 2-10X shorter than the equivalent Java program. This translates
directly to increased programmer productivity. The seamless interaction between Python and Java
allows developers to freely mix the two languages both during development and in shipping
products.

To make a jython script executable on your system you can add the following line to the top of the file:

#!/usr/bin/env jython

You will also need to add execute permissions to the script using chmod(1). Note that #!/usr/bin/jython
will not work; you must use #!/usr/bin/env jython. This is because /usr/bin/jython is a script itself,
not a compiled binary.

OPTIONS

       A summary of options is included below.

       -i     Continue running Jython interactively after running the given script, and force  prompts  even  if
              standard input doesn't appear to be a terminal.

       -S     Don't imply import site on initialisation.

       -v     Trace import statements on error output.

       -Dproperty=value
              Set the Jython property property to value; see jython.conf(5) for details of available properties.

       -Wargument
              Warning control. The full form of argument is action:message:category:module:line.  Trailing empty
              fields may be omitted. Multiple -W options may be given.  See documentation of the warnings module
              for details.

       -Ecodec
              Set the encoding used to read module source files from disk.

       -Qargument
              Division control. See PEP 239 for details. Valid arguments are old, new, warn and warnall.

       -jar jar
              The program to run is read from the file __run__.py in the specified jar archive.

       -c cmd The program to run is passed as the cmd string.  This option terminates the options list.

       file   The program to run is the script file.

       -      The  program  to run is read from standard input (default behaviour).  Interactive mode is used if
              running on a tty.  This flag allows you to pipe  a  file  into  Jython  and  have  it  be  treated
              correctly.

       script-args
              Command-line arguments to pass to the Jython script in sys.argv[1:].

       --help Print a usage message and exit.

       --version
              Print the Jython version number and exit.

ENVIRONMENT VARIABLES

       JAVA (default: /usr/bin/java)
              The Java interpreter to use when running Jython.

       JAVA_OPTIONS (default: empty)
              Options to pass to the Java interpreter when running Jython.
