Issue1783

On Mac OS X Lion and a fresh installation of Jython 2.5.2, there are no Jython Options meaning I can't increase the heap space for my help. Here are the results of 'help':

usage: jython [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options and arguments:
-c cmd   : program passed in as string (terminates option list)
-Dprop=v : Set the property `prop' to value `v'
-C codec : Use a different codec when reading from the console.
-h       : print this help message and exit (also --help)
-i       : inspect interactively after running script
           and force prompts, even if stdin does not appear to be a terminal
-jar jar : program read from __run__.py in jar file
-m mod   : run library module as a script (terminates option list)
-Q arg   : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew
-S       : don't imply 'import site' on initialization
-u       : unbuffered binary stdout and stderr
-v       : verbose (trace import statements)
-V       : print the Python version number and exit (also --version)
-W arg   : warning control (arg is action:message:category:module:lineno)
file     : program read from script file
-        : program read from stdin (default; interactive mode if a tty)
arg ...  : arguments passed to program in sys.argv[1:]
Other environment variables:
JYTHONPATH: ':'-separated list of directories prefixed to the default module
            search path.  The result is sys.path.



The options show up on an installation of CentOS.

Sorry this never got answered. The answer is that you can pass args to the Java side with -J. So for increasing max memory to 1024m you would do this:

jython -JXmx1024m

Closing.

Oops that was not quite right, should be (note the extra dash):

jython -J-Xmx1024m
