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). 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. 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.

It can thus be used as a sys.excepthook for Python > 2.1. Also adds 'Context' and 'Verbose' modes, not available in ListTB. Allows a tb_offset to be specified. This is useful for situations where one needs to remove a number of topmost frames from the traceback (such as occurs with python programs that themselves execute other python code, like Python shells). uPlainuLinuxic Csdddg|_|jdd!|_tj|d|d|d|d |d |d |d |td ddddd|_|j|dS(NuPlainuContextuVerboseiiRRRR\RRRtPlainutContextu tVerbose(t valid_modest verbose_modesRRtdictt _join_charstset_mode( RRRRRR\RRR((sL/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/core/ultratb.pyR^s  cCs|rtj|SdSdS(N(RSRTR(RR((sL/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/core/ultratb.pyt _extract_tbrs icCs|dkr|jn|}|j}||jkrOtj||||||S|j|j|}tj||||||SdS(N( RR\RRSRRRRWR(RRRRR\R1RR((sL/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/core/ultratb.pyRxs  cCs|jj|S(u4Convert a structured traceback (a list) to a string.(t tb_join_charR(RR((sL/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/core/ultratb.pyRscCs|s?|jj|jdt|j}|j||_n<||jkrrtd|dt|jn ||_|j|jdk|_|j|j|_dS(ubSwitch to the desired mode.
