DDD – graphical front-end for command-line debuggers

Last Updated on July 10, 2021

The Data Display Debugger (DDD) is a popular graphical user interface to debuggers such as GDB, DBX, XDB, JDB and others.

The purpose of a debugger such as DDD is to allow you to see what is going on “inside” another program while it executes — or what another program was doing at the moment it crashed.

Besides ‘usual’ front-end features such as viewing source texts and breakpoints, DDD provides an interactive graphical data display, where data structures are displayed as graphs.

Using DDD, you can reason about your application by watching its data, not just by viewing it execute lines of source code.

Features include:

  • Debugging of programs written in Ada, Bash, C, C++, Chill, Fortran, Java, Modula, Pascal, Perl and Python.
  • Machine-level debugging.
  • Hypertext source navigation and lookup.
  • Breakpoint, backtrace, and history editors.
  • Preferences and settings editors.
  • Program execution in terminal emulator window.
  • Debugging on a remote host.
  • On-line manual interactive help.
  • GDB / DBX / XDB command-line interface with full editing, history, and completion capabilities.
