Various command line interface utilities.
This package requires Python 2, at least 2.5.
tl.cmd: an enhanced command shell
tl.cmd.Cmd is a command shell based on Python’s cmd.Cmd that adds some generic usability features, some of them only of interest to developers.
- Exceptions are caught instead of aborting the command loop. The traceback is stored for subsequent introspection by the postmortem debugger. The debugger is run by the postmortem command.
- The python command runs a Python shell to access the command interpreter directly.
- End-of-file sent by the terminal quits the command loop.
- Empty input lines are ignored instead of repeating the previous command.
- Commands may be abbreviated as long as abbreviations are unambiguous.
- When using tab completion, the cursor is positioned more conveniently.
- Online help for commands is generated from the docstrings of the do_* methods that implement them where no help_* methods exist.
