  • Towards a Standard Parser Generator

    ...program. The generated parsers need to support parsing of Unicode strings. Although this requirement is specific to XPath, Unicode support is desirable whenever the input may come in different encodings. In addition, the following non-critical criteria are used for ranking the parsers: Since the XSL Transformations [W3C99a] are a primary application for XPath expressions, and since many short expressions occur in a typical XSLT style sheet, it is desirable...

    ...programs (for example, ZoneAlarm) open a dialog of their own when any program opens a socket. IDLE does use sockets, talking on the computer's internal loopback interface. This connection is not visible on any external interface and no data is sent to or received from the Internet. So, if you get such a dialog when opening IDLE, asking whether to let pythonw.exe talk to address 127.0.0.1, say yes, and rest assured no communication external to your machine is taking place. If you don't allow ...

It could be argued that NameError and AttributeError should be derived from LookupError, but this is questionable and depends entirely on the application. Exception Class Definitions The Python class definitions for the standard exceptions are imported from the standard module "exceptions". You can't change this file thinking that the changes will automatically show up in the standa...

You can now override the 'in' operator by defining a __contains__ method. Note that it has its arguments backwards: x in a causes a.__contains__(x) to be called. That's why the name isn't __in__. The exception AttributeError will have a more friendly error message, e.g.: 'Spam' instance has no attribute 'eggs'. This may break code that expects the message to be...

Maybe people will rethink registering, or help publicize more. Maybe it's too whiny. Issue for discussion: given that we've signed a 2-year contract, what do we do for 2007? Options I can think of: Try to be released from the contract. This is only worth doing if it's free. If we have to pay the $70000 penalty, it's better t...
