GDB dashboard: debug info at a glance

https://github.com/cyrus-and/gdb-dashboard

GDB dashboard is a useful python utility for programmers to show valuable information while debugging with gdb. It uses the gdb python interface of gdb and implements several modules in different categories to show debug information:

assembly: disassembled code
expressions: watches user expressions
history: last entries in gdb value history
memory: inspect contiguous memory locations
registers
source (if available)
stack: current stack trace
threads

All the modules are enabled by default.

Features

Single GDB init file
Interaction with GDB using the native Python API
Several default modules are included to address the most basic needs: source code, assembly, registers, etc.)
User-defined modules can be easily developed by extending a Python class
Additional configuration files (both GDB and Python) are read from ~/.gdbinit.d/ F- ully stylable user interface and dynamic command prompt
No GDB command has been redefined, instead all the features are available as subcommands of the main dashboard command
Installation

Clone the GutHub repo and copy the file in your home directory:

$ git clone https://github.com/cyrus-and/gdb-dashboard
$ cp gdb-dashboard/.gdbinit ~/

Usage

GDB dashboard is loaded when gdb is invoked, thanks to the ~/.gdbinit file. The dashboard can be shown whenever the program stops. By default it is turned off. Use the following command within gdb to change the behaviour:

>>> dashboard -enabled [on|off]

To show the dashboard:

>>> dashboard

To change the layout, e.g., show only assembly, expressions and registers and disable source, run:

>>> dashboard -layout assembly expressions registers !source

As you can understand, it’s very simple to extend this framework. For more information, hit the project page.
