3 | 3 | Pdb debugger class. |
|
4 | 4 | |
|
5 | 5 | Modified from the standard pdb.Pdb class to avoid including readline, so that |
|
6 | 6 | the command line completion of other programs which include this isn't |
|
7 | 7 | damaged. |
|
8 | 8 | |
|
9 | 9 | In the future, this class will be expanded with improvements over the standard |
|
10 | 10 | pdb. |
|
11 | 11 | |
|
12 | 12 | The code in this file is mainly lifted out of cmd.py in Python 2.2, with minor |
|
13 | 13 | changes. Licensing should therefore be under the standard Python terms. For |

|
85 | 85 | |

86 | 86 | This is implemented as a class which must be initialized in your own code |
