 # Debugger
 
-After some tryouts it ended up being an Opal application. That is ruby as javascript in the browser.

-![Debugger](https://raw.githubusercontent.com/salama/salama-debugger/master/static/debugger.png)
-
-- On the left are the classes of the system. Next idea is to have hover info about them.
-- Next a source code view (not implemented)
-- next a view of the Virtual Instructions
-- last section, current block with current Register Instruction highlighted
-- step (next) button for single stepping
-- status: starting , running , exited
-- bottom row are the registers. If the register hold an object the variables are shown.
-    (also should have hover info) , the first letter indicates the class, the number is the address
-
-So lots to do, but a good start.
-
-
-
 I don't want to use gdb anymore, and it would be easier without using the qemu setup, so:
 
 - single step debugging of the register machine level (as close to arm as need be)
