The ColorTB class is a solution to that problem. It colors the different parts of a traceback in a manner similar to what you would expect from a syntax-highlighting text editor. Installation instructions for ColorTB:: import sys,ultratb sys.excepthook = ultratb.ColorTB() **VerboseTB** I've also included a port of Ka-Ping Yee's "cgitb.py" that produces all kinds of useful info when a traceback occurs. Ping originally had it spit out HTML and intended it for CGI programmers, but why should they have all the fun? I altered it to spit out colored text to the terminal. It's a bit overwhelming, but kind of neat, and maybe useful for long-running programs that you believe are bug-free. If a crash *does* occur in that type of program you want details. Give it a shot--you'll love it or you'll hate it. .. note:: The Verbose mode prints the variables currently visible where the exception happened (shortening their strings if too long). This can potentially be very slow, if you happen to have a huge data structure whose string representation is complex to compute. Your computer may appear to freeze for a while with cpu usage at 100%. If this occurs, you can cancel the traceback with Ctrl-C (maybe hitting it more than once). If you encounter this kind of situation often, you may want to use the Verbose_novars mode instead of the regular Verbose, which avoids formatting variables (but otherwise includes the information and context given by Verbose). .. note:: The verbose mode print all variables in the stack, which means it can potentially leak sensitive information like access keys, or unencrypted password. Installation instructions for VerboseTB:: import sys,ultratb sys.excepthook = ultratb.VerboseTB() Note: Much of the code in this module was lifted verbatim from the standard library module 'traceback.py' and Ka-Ping Yee's 'cgitb.py'. Color schemes ------------- The colors are defined in the class TBTools through the use of the ColorSchemeTable class. Currently the following exist: - NoColor: allows all of this module to be used in any terminal (the color escapes are just dummy blank strings). - Linux: is meant to look good in a terminal like the Linux console (black or very dark background). - LightBG: similar to Linux but swaps dark/light colors to be more readable in light background terminals. - Neutral: a neutral color scheme that should be readable on both light and dark background You can implement other color schemes easily, the syntax is fairly self-explanatory. Please send back new schemes you develop to the author for possible inclusion in future releases.

The 'force' option forces the debugger to activate even if the flag is false. If the call_pdb flag is set, the pdb interactive debugger is invoked. In all cases, the self.tb reference to the current traceback is deleted to prevent lingering references which hamper memory management.
