Pdb debugger class.
|
|
|
|
|
|
Modified from the standard pdb.Pdb class to avoid including readline, so that
|
|
|
the command line completion of other programs which include this isn't
|
|
|
damaged.
|
|
|
|
|
|
In the future, this class will be expanded with improvements over the standard
|
|
|
pdb.
|
|
|
|
|
|
The code in this file is mainly lifted out of cmd.py in Python 2.2, with minor
|
|
|
changes. Licensing should therefore be under the standard Python terms. For

DEPRECATED
|

|

Class for local debugging, similar to pdb.set_trace.
|
|
|
|
|
|
Instances of this class, when called, behave like pdb.set_trace, but
|
|
|
providing IPython's enhanced capabilities.
|
|
|
|
|
|
This is implemented as a class which must be initialized in your own code
|
|
|
and not as a standalone function because we need to detect at runtime
|
|
|
whether IPython is already active or not. That detection is done in the
|
|
|
constructor, ensuring that this code plays nicely with a running IPython,
|
|
|
while functioning acceptably (though with limitations) if outside of it.

Parameters
|
|
|
----------
|

|
|
|
|
colors : str, optional
|
|
|
The name of the color scheme to use, it must be one of IPython's

the current IPython scheme when running inside IPython, and to

Examples

--------

|
::
