aenum 3.1.1 released
by Ethan Furman 30 Oct '21

30 Oct '21

aenum --- support for advanced enumerations, namedtuples, and constants =========================================================================== Advanced Enumerations (compatible with Python's stdlib Enum), NamedTuples, and NamedConstants aenum includes a Python stdlib Enum-compatible data type, as well as a metaclass-based NamedTuple implementation and a NamedConstant class. An Enum is a set of symbolic names (members) bound to unique, constant values. Within an enumeration, the members can be compared by identity, and the enumeration itself can be iterated over. If using Python 3 there is built-in support for unique values, multiple values, auto-numbering, and suspension of aliasing (members with the same value are not identical), plus the ability to have values automatically bound to attributes. A NamedTuple is a class-based, fixed-length tuple with a name for each possible position accessible using attribute-access notation as well as the standard index notation. A NamedConstant is a class whose members cannot be rebound; it lacks all other Enum capabilities, however; consequently, it can have duplicate values.

oxidized_importer 0.3 released
by Gregory Szorc 25 Oct '21

25 Oct '21

oxidized_importer - a pure Rust Python extension module implementing high performance Python module importers - version 0.3 has been released. The documentation is available at https://pyoxidizer.readthedocs.io/en/oxidized-importer-0.3/oxidized_importe… . Like previous versions of this extension module, version 0.3 supports importing Python modules and resources from memory or from memory mapped files using the OxidizedFinder class. This is the special importer that enables PyOxidizer to generate single file Python applications without relying on run-time extraction of Python modules to a filesystem. New in version 0.3 is the OxidizedZipFinder ( https://pyoxidizer.readthedocs.io/en/oxidized-importer-0.3/oxidized_importe…) class, which aims to be a drop-in replacement for zipimport.zipimporter. While not quite reaching that goal, this zip file importer is already considerably faster than the one in the Python standard library and can often be leveraged by existing users of zipimport wishing to shave precious milliseconds off application startup overhead. OxidizedZipFinder isn't as fast as OxidizedFinder. But it provides competitive performance while hopefully retaining sufficient compatibility with zipimport. oxidized_importer is developed as part of the PyOxidizer Project and feedback can be submitted via GitHub issues at https://github.com/indygreg/PyOxidizer.
