资源说明：Capture and Replay javascript in javascript (no plugins - by only instrumenting javascript)

There are two eclipse projects at the root level: JSCaptureReplay and DebugMonitorWeb. 
TODO: extend README to non-eclipse dev environments.

INSTALL and RUNNING:
1. Install the JEE version of Eclipse or install JEE environment in your installed Eclipse.
2. Import the two projects into eclipse using Import -> Existing projects into workspace.
3. In DebugMonitorWeb -> props -> carjsweb.properties; replace the jscar_func.log and jscar_rand.log file paths to some writable location in your system.
4. Make sure that src files in DebugMonitorWeb and JSCaptureReplay have compiled successfully.
5. Install Tomcat (v6 was tested, but v5 or other java web servers should be ok) and add the server in eclipse (using eclipse's new -> server...). Add DebugMonitorWeb to the server projects.
6. To test the installation: start the server. Go to http://localhost:8080/DebugMonitorWeb/tetris/tetris.html . Play the game for a while. Now check the jscar_func.log and jscar_rand.log; these files should have some data related to the execution. Now go to http://localhost:8080/DebugMonitorWeb/tetris/replay.html, and you should be able to replay the execution using the replay controller popup window.

INSTRUMENTING NEW APPLICATION:
JSCaptureReplay is the project that instruments a given javascript file. Use this class to instrument:
org.gt.carjs.CarJSMain   

Two more files contribute to the javascript instrumentation. DebugMonitorWeb -> WebContent -> carjs -> capture/replay.js. These two javascript files contain instrumentation irrespective of application.

For instrumenting a new application:
1. Take every script in the HTML page - say: S1: , S2: . For S1, take the contents between the script tags and run it through CarJSMain to output S1*. For S2, run the file blah.js through CarJSMain -> S2*.
2. Create 2 copies of the original HTML file, say capture.html and replay.html. In both capture.html and replay.html include carjs/util.js and then carjs/capture.js or carjs/replay.js respectively, before any other scripts. 
3. S1 and S2 would have been at some specific places in the HTML page. Replace them with  S1* and S2*.
4. In capture.html and replay.html add this script at the very end. It should be the last piece of script on the page.
Script:

See examples.
5. In summary, you would have capture.html with util.js, capture.js and S1* and S2*. Replay.html would have util.js, replay.js, S1* and S2*. Both would have the small script at the end. Look at the instrumented examples under DebugMonitorWeb/webcontent/application_name where application_name=tetris, wave, battleship and domtris.
6. *IGNORE* the applications breakout, minesweeper and viz. TODO: remove them from git.
