This python script adds a new window containing variables to watch when debugging a program under GDB.
Clone this repository and add the following line into your ~/.gdbinit (or ~/.gdbrc) file
source <pathToThisRepo>/watchVariable.py
source <pathToThisRepo>/watchRegisters.py
tui new-layout watchVariable {-horizontal src 2 watchVariable 1} 2 cmd 1 status 1
tui new-layout watchRegisters {-horizontal asm 2 watchRegisters 1} 2 cmd 1 status 1
layout watchVariable
The python script is adding one new TUI window type and 2 user commands add-variable-to-watch, remove-variable-to-watch (see below)
When starting GDB, the layout of the debugger should ressemble to the screenshot (unless you have omited the layout watchVariable line).
To add a new variable to watch, use the command add-variable-to-watch. The new variable will appear in the Variables window.
To remove a variable to watch, use the command remove-variable-to-watch.
Switch from variable view to CPU register by using the command
layout watchRegisters
layout watchVariable
By default, gdb outputs all the numbers in decimal mode. Use the command set output-radix 16 to print all the variables in the watcher in hexadecimal.
