CONSOLE_LOG_FORMAT
The default format for console log messages in the command-line Jython. Seejava.util.logging.SimpleFormatter
for an explanation of the syntax.This format is used in the absence of other logging preferences. Jython tests for definitions in the system properties of
java.util.logging.config.class
,java.util.logging.config.file
, andjava.util.logging.SimpleFormatter.format
and if none of these is defined, it sets the last of them to this value.You can choose something else, for example to log with millisecond time stamps, launch Jython as:
jython -vv -J-Djava.util.logging.SimpleFormatter.format="[%1$tT.%1$tL] %3$s: (%4$s) %5$s%n"
Depending on your shell, the argument may need quoting or escaping.- See Also:

runJar
Runs a JAR file, by executing the code found in the file __run__.py, which should be in the root of the JAR archive. Note that__name__
is set to the base name of the JAR file and not to "__main__" (for historical reasons). This method does not handle exceptions. the caller should handle any(Py)Exceptions
thrown by the code.- Parameters:
filename
- The path to the filename to run.- Returns:
0
on normal termination (otherwise throwsPyException
).

run
Deprecated.Now equivalent tomain(String[])
, which is to be preferred. -
main
Main Jython program, following the structure and logic of CPythonmain.c
to produce the same behaviour. The argument to the method is the argument list supplied after the class name in thejava
command. Arguments up to the executable script name are options for Jython; arguments after the executable script are supplied insys.argv
. "Executable script" here means a Python source file name, a module name (following the-m
option), a literal command (following the-c
option), or a JAR file name (following the-jar
option). As a special case of the file name, "-" is allowed, meaning take the script from standard input.The main difference for the caller stems from a difference between C and Java: in C, the argument list
(argv)
begins with the program name, while in Java all elements of(args)
are arguments to the program.- Parameters:
args
- arguments to the program.
