Data Display Debugger, or DDD, is a popular free software (under the GNU GPL) graphical user interface (using the Motif toolkit) for command-line debuggers such as GDB, DBX, JDB, HP Wildebeest Debugger (WDB), XDB, the Perl debugger, the Bash debugger, the Python debugger, and the GNU Make debugger. DDD is an entry in the GNU Project.
DDD has GUI front-end features such as viewing source texts and its interactive graphical data display, where data structures are displayed as graphs.
A simple mouse click dereferences pointers or views structure contents, updated each time the program stops. Using DDD, you can reason about your application by watching its data, not just by viewing it execute lines of source code.
DDD is used primarily on Unix systems, and its usefulness is complemented by many open source plug-ins available for it.
Famous quotes containing the words data and/or display:
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
“Housekeeping is not beautiful; it cheers and raises neither the husband, the wife, nor the child; neither the host nor the guest; it oppresses women. A house kept to the end of prudence is laborious without joy; a house kept to the end of display is impossible to all but a few women, and their success is dearly bought.”
—Ralph Waldo Emerson (1803–1882)
