Here's what works for Cygwin users:

1. Use a DOS prompt and forget about the headaches of Cygwin. 2. Use Cygwin bash in a DOS window: jython.bat works there. 3. Use Cygwin xterm/rxvt/etc. with the modified jython script for interactive session and jython.bat (or unmodified jython) for non-interactive usage.

The ultimate solution of this problem would require two things:

1. Fix JLine so that it works with Cygwin xterm/rxvt/etc. 2. Fix Jython so that it uses the correct JLine Terminal under Cygwin.

I was thinking #2 would make sense. I think it's reasonable to ship some analog to your shell script with the stty/JLine stuff conditionalized to cygwin, as I'd guess the interactive usage scenario is a lot more common.

I've committed a fix for #2. It's basically Weiqi's changes but mostly stolen from JRuby as our script derives from there's (and we try to keep the two in sync):

Weiqi and other cygwin users, could you download the new jython command line script and give it a shot?

https://jython.svn.sourceforge.net/svnroot/jython/trunk/jython/src/shell/jython

You'll still need the jython -i workaround for the prompt/isatty issue. You can also make that happen via JYTHON_OPTS="-i"

It works as advertised on my Cygwin xterm, Cygwin bash in a CMD window, Cygwin rxvt[*], and Cygwin MinTTY. The Arrow keys, Home, End, C-a/C-e, C-f/C-b, C-n/C-p all work as expected.

[*] The Home/End keys does not work under rxvt.

I still see the stty error messages when doing

echo "print 10" | jython

Redirecting the the error messages to /dev/null should fix that.

Thanks, Philip!
