The e++ Debugger (EDB)

General Features

These are the general features of the e++ Debugger (EDB):

• Runs in a browser window that alternately contains the debugger or the client screen

• Allows setting and resetting of breakpoints

• Allows step-into, step over functions

• Allows display of variables

• Allows editing of e++ code and restarting of an e++ program

• Allows cancellation of execution

• Has a "watch window" that shows generated code

• Allows restart of the entire program

Running EDB

To run the debugger, set eppdebug=1 on the URL. [what if the URL is HTML?  won't go to epp]  This will cause an automatic stayalive until the program is cancelled or the program terminates.  If the program terminates, control will return to the debugger client screen.  The program may then be be restarted.

Javascript

The debugger client is written in Javascript.

Next Step

Run any code in the debugger to see how it works.

Run the CodeScript debugger under a debugger to figure out how the debugger works.
