jython.conf - Jython registry for system-wide options
When running jython(1) or jythonc(1), a number of properties may be set
to customise Jython's behaviour. Properties can be assigned values in
any of the following four ways. This list is arranged from lowest to
highest priority; thus for instance a property set in a user's personal
registry will override the same property set in the system-wide
Java system properties
Jython options may be set in the standard Java system
properties. However, since the jython and jythonc startup
scripts take responsibility for starting the Java interpreter,
it is unlikely that you will use this method of Jython
Jython system-wide registry
The system-wide registry is the file /etc/jython/jython.conf.
It contains a number of lines of the form property=value. Lines
that are empty or that begin with a hash (#) are ignored.
User's personal registry
The user's personal registry is the file ~/.jython. Its format
is the same as for the system-wide registry.
Properties may be specified when running jython or jythonc at
the command-line. They are set using command-line options of
the form -Dproperty=value.
The following properties may be set in the Jython registry. Other less
used properties are also available; see the comments in the default
system-wide registry for further details.
If a property is marked (auto), the jython and jythonc startup scripts
will attempt to set this property automatically, although it can still
be overridden in the system or user registry or on the command-line.
The directory to use for caches (currently just package
information). This directory must be writable by the user. If
the directory is an absolute path then it is used as given;
otherwise it is interpreted as relative to the root Jython
The name of the console class to use when running Jython from
the command prompt. An alternative console class that emulates
GNU readline can be specified using this property.
Extensions to the Java property java.class.path for use with
jythonc. This is used to put extra classes on your Java
compiler's classpath (and the core Java classes as well if your
Java compiler requires them).
The Java compiler to use with jythonc when turning generated
Java code into Java class files. This should be the absolute
path to a Java compiler, or the name of a compiler on your
Options to pass to the Java compiler when using jythonc.
The path on which Jython will look for additional python modules
when importing. This variable has a similar function to
CPython's PYTHONPATH environment variable.
Normally, Jython can only provide access to public members of
classes. However if this property is set to false and you are
using Java 1.2 then Jython can access non-public fields, methods
Sets the verbosity level for informative messages. All messages
with at least the specified severity will be displayed. Valid
values in order of increasing verbosity are error, warning,
message, comment and debug.
If the Debian package jython-doc is installed, full documentation from
the Jython authors will be available in /usr/share/doc/jython-
This manual page was prepared by Ben Burton <firstname.lastname@example.org> for the
Debian GNU/Linux system (but may be used by others). It is based upon
the official Jython documentation.
