"""More comprehensive traceback formatting for Python scripts.
|
2001-08-18 01:04:50 -03:00
|
|
|
|
|
|
|
|
To enable this module, do:
|
|
|
|
|
|
|
|
|
|
import cgitb; cgitb.enable()
|
|
|
|
|
|
2003-06-17 09:58:31 -03:00
|
|
|
at the top of your script. The optional arguments to enable() are:
|
2001-08-18 01:04:50 -03:00
|
|
|
|
|
|
|
|
display - if true, tracebacks are displayed in the web browser
|
|
|
|
|
logdir - if set, tracebacks are written to files in this directory
|
2001-08-21 03:53:01 -03:00
|
|
|
context - number of lines of source code to show for each stack frame
|
2003-06-29 02:46:54 -03:00
|
|
|
format - 'text' or 'html' controls the output format
|
2001-08-18 01:04:50 -03:00
|
|
|
|
2003-06-17 09:58:31 -03:00
|
|
|
By default, tracebacks are displayed but not saved, the context is 5 lines
|
|
|
|
|
and the output format is 'html' (for backwards compatibility with the
|
|
|
|
|
original use of this module)
|
2001-08-18 01:04:50 -03:00
|
|
|
|
|
|
|
|
Alternatively, if you have caught an exception and want cgitb to display it
|
2003-06-17 09:58:31 -03:00
|
|
|
for you, call cgitb.handler(). The optional argument to handler() is a
|
|
|
|
|
3-item tuple (etype, evalue, etb) just like the value of sys.exc_info().
|
|
|
|
|
The default handler displays output as HTML.

Remove the imageop module. With imgfile already removed in Python 3.0 and
rgbimg gone in Python 2.6 the unit tests themselves were made worthless. Plus
third-party libraries perform the same function much better.
