[activator-1.2.3] - cygwin bash can't display anything while typing after exit from activator

[keepscoding]

When i run activator from my play project and then ctrl+D to exit from activator, I continue to use cygwin bash for other commands or relaunch my play.

Then when i try to type, i can't see the characters\text\command that i'm typing. When i hit enter, i can see the bash responsed to what i've typed. 

Anyone has this problem( James, do u) ? I asked around ppl using cygwin bash. they have not encountered this problem from thier project(not doing play or using activator). 

I'm using cygwin 64bit win8.1 pro.

isn't got to do with this in activator when exit?

  local exit_code=$?

  if is_cygwin; then

    stty icanon echo > /dev/null 2>&1

  fi

  exit $exit_code

}

soweone pointed out to me in stackoverflow.. that below line causes the problem... i think activator exit without un-silent back the cywin...

stty -icanon min 1 -echo > /dev/null 2>&1

[keepscoding]

Tested.. it is the culprit...

Have you figured out a workaround for this?  i love to use cygwin, but having to restart it after every 'activator' command is a bit much...

Try typing one of these next time the problem occurs:

stty sane

or (this is a heavier hammer)

reset

[keepscoding]

No. Still the same problem unless u comment the line i mentioned.

I've been working on my own script which uses stty -icanon command mentioned earlier.  I found to restore terminal functionality after setting non canonical read, the terminal settings had to be saved beforehand. Doing a 'stty sane' did not work.  Here's some example code

SAVE_TERM="$(stty -g)"       # save terminal settings

stty -icanon                             # non canonical read 

stty $SAVE_TERM                # restore terminal settings

If the user does ctr-c, you can add 

trap "stty $SAVE_TERM" SIGINT SIGTERM

The regular scala runner script does this, as well.

I also find the same problem with Activator 1.3.4 on Cygwin. Is there a patched script somewhere that fixes this problem?
