  • Towards a Standard Parser Generator

    ...modules are required for the parser, to simplify installation of a generated parser. If C modules are required, then parsers whose C modules are independent from the input language rank better than parsers which generate C code dependent on the input language. If a parser generator uses a generic C module, than this module might get included in the Python core one day, and thus be available for all generated parsers. A parser generator for Python should be easy to use...

Cleaned up definition of NULL in C source code; all definitions were removed and add #error to Python.h if NULL isn't defined after #include of stdio.h. Py_PROTO() macros that were removed in 2.0b1 have been restored for backwards compatibility (at the source level) with old extensions. A wrapper API was added for signal() and sigaction(). Instead of either func...

  • Standard Exception Classes in Python 1.5

You can't change this file thinking that the changes will automatically show up in the standard exceptions; the builtin module expects the current hierarchy as defined in exceptions.py. Details on the standard exception classes are available in the Python library reference manual's entry for the exceptions module. Changes to raise The raise statement has b...

See questions 4.2, 4.19 and in particular 6.22 in the Python FAQ for more on this topic.) The base class is B; this one's easy. Since B is a class, its type is ``class''; so the type of the base class is the type ``class''. This is also known as types.ClassType, assuming the standard module types has been imported. Now is the type ``class'' callable? No, beca...

    ...modules is now greatly automated. Rather than having to edit the Modules/Setup file to indicate which modules should be built and where their include files and libraries are, a distutils-based setup.py script now takes care of building most extension modules. All extension modules built this way are built as shared libraries. Only a few modules that must be linked statically are still listed in the Setup file; you won't need to edit their configuration. Python should now build out of the box ...
