Why?
Because it's an obvious application for OO design. A common base class formalizes the interface and can provide useful utilities for subclasses.
The interface is just one function. You're welcome to have a do-nothing nanny that people *can* derive from: I see no point in making them derive from a base class.
As a note, selfnanny uses the parser module AST.
Understood, but selfnanny has a relatively trivial task.
That it does, and it was painful.
[parser doesn't give source lines]
The parser module has source lines.
No, it does not (it only returns terminals, as isolated strings).
Sorry, misunderstanding: it seemed obvious to me you wanted line numbers. For lines, use the linecache module...
You got some pointers?
Download python2c (http://www.mudlib.org/~rassilon/p2c/) and grab transformer.py from the zip file.
I'll have a look. Moshe Zadka <mzadka@geocities.com>. http://www.oreilly.com/news/prescod_0300.html
