Scramjet for UNIX: Java acceleration for terminal apps
This fully usable but still a work-in-progress. I am adding new features and reorganizing old ones as I need them, according to how much free time I get to work on it. --Jim
Main applications
- UNIX command-line tools: Scramjet allows fast UNIX-style command-line tools to be written in Java by avoiding the JVM startup time.
- UNIX terminal applications: Scramjet allows writing efficient ncurses-style fullscreen Unicode ANSI text applications (editors, mail agents, viewers) in Java.
- Eclipse hooks: Scramjet allows monolithic Java applications such as Eclipse to be controlled from the UNIX command-line, running commands on demand within the Eclipse JVM, with input/output via the terminal.

Quick-Start and Example Usage
# Build everything
cd src
./mk
# Start JVM (also creates ~/.scramjet the first time)
out/scramjet -S
# Kill JVM
out/scramjet -K
# Start JVM (automatically) and show test page. NOTE: you might need
# to press ^L (redraw) to display line-characters correctly on some
# GNOME terminals -- this seems to be a libVTE bug.
out/scramjet net.uazu.scramjet.test.ConsoleTest0
^C
# If something was not working on the test page, adjust LANG and TERM
# environment variables as required and re-run as necessary. We need
# -R option here to restart the JVM to get it to pick up LANG changes.
export LANG=...
export TERM=...
out/scramjet -R net.uazu.scramjet.test.ConsoleTest0
^C
# Start a game. (NOTE: both dots and slashes are okay for package
# separators)
out/scramjet net/uazu/scramjet/test/Teeclub
# Whilst it is running, on another terminal show the stacktraces of
# all the threads running in the JVM.
out/sj-threads -l
