org.python.core.Options

public class Options
extends Object

A class with static fields for each of the settable options. The options from registry and command line is copied into the fields here and the rest of Jython checks these fields.

Field Summary

Fields

Modifier and Type	Field and Description
static int	bytes_warning
static boolean	caseok If true, Jython will use the first module found on sys.path where java File.isFile() returns true.
static int	division_warning Enable division warning.
static boolean	dont_write_bytecode Whether -B (don't write bytecode on import) was enabled via the command line.
static boolean	ignore_environment Whether -E (ignore environment) was enabled via the command line.
static boolean	importSite When false the site.py will not be imported.
static boolean	includeJavaStackInExceptions If true, exceptions raised from Python code will include a Java stack trace in addition to the Python traceback.
static boolean	no_site
static boolean	no_user_site
static int	optimize
static String	proxyDebugDirectory A directory where the dynamically generated classes are written.
static boolean	py3k_warning Whether -3 (py3k warnings) was enabled via the command line.
static boolean	Qnew If true, enable truedivision for the '/' operator.
static boolean	respectJavaAccessibility If true, Jython respects Java the accessibility flag for fields, methods, and constructors.
static boolean	showJavaExceptions when an exception occurs in Java code, and it is not caught, should the interpreter print out the Java exception in the traceback?
static boolean	showPythonProxyExceptions When true, python exception raised in overridden methods will be shown on stderr.
static String	sreCacheSpec
static String	sreCacheSpecDefault Cache spec for the SRE_STATE code point cache.
static boolean	unbuffered Force stdin, stdout and stderr to be unbuffered, and opened in binary mode
static int	verbose Set verbosity to Py.ERROR, Py.WARNING, Py.MESSAGE, Py.COMMENT, or Py.DEBUG for varying levels of informative messages from Jython.

Field Detail

showJavaExceptions

public static boolean showJavaExceptions

when an exception occurs in Java code, and it is not caught, should the interpreter print out the Java exception in the traceback?

includeJavaStackInExceptions

public static boolean includeJavaStackInExceptions

If true, exceptions raised from Python code will include a Java stack trace in addition to the Python traceback. This can slow raising considerably.

showPythonProxyExceptions

public static boolean showPythonProxyExceptions

When true, python exception raised in overridden methods will be shown on stderr. This option is remarkably useful when python is used for implementing CORBA server. Some CORBA servers will turn python exception (say a NameError) into an anonymous user exception without any stacktrace. Setting this option will show the stacktrace.

respectJavaAccessibility

public static boolean respectJavaAccessibility

If true, Jython respects Java the accessibility flag for fields, methods, and constructors. This means you can only access public members. Set this to false to access all members by toggling the accessible flag on the member.

importSite

public static boolean importSite

When false the site.py will not be imported. This is only honored by the command line main class.

verbose

public static int verbose

Set verbosity to Py.ERROR, Py.WARNING, Py.MESSAGE, Py.COMMENT, or Py.DEBUG for varying levels of informative messages from Jython. Normally this option is set from the command line.

proxyDebugDirectory

public static String proxyDebugDirectory

A directory where the dynamically generated classes are written. Nothing is ever read from here, it is only for debugging purposes.

caseok

public static boolean caseok

If true, Jython will use the first module found on sys.path where java File.isFile() returns true. Setting this to true have no effect on unix-type filesystems. On Windows/HFS+ systems setting it to true will enable Jython-2.0 behaviour.

Qnew

public static boolean Qnew

If true, enable truedivision for the '/' operator.

unbuffered

public static boolean unbuffered

Force stdin, stdout and stderr to be unbuffered, and opened in binary mode

py3k_warning

public static boolean py3k_warning

Whether -3 (py3k warnings) was enabled via the command line.

dont_write_bytecode

public static boolean dont_write_bytecode

Whether -B (don't write bytecode on import) was enabled via the command line.

ignore_environment

public static boolean ignore_environment

Whether -E (ignore environment) was enabled via the command line.

no_user_site

public static boolean no_user_site

no_site

public static boolean no_site

bytes_warning

public static int bytes_warning

optimize

public static int optimize

division_warning

public static int division_warning

Enable division warning. The value maps to the registry values of

• old: 0
• warn: 1
• warnall: 2

sreCacheSpecDefault

public static final String sreCacheSpecDefault

Cache spec for the SRE_STATE code point cache. The value maps to the CacheBuilderSpec string and affects how the SRE_STATE cache will behave/evict cached PyString -> int[] code points.

sreCacheSpec

public static String sreCacheSpec

Method Detail

setFromRegistry

public static void setFromRegistry()
