ANNOUNCE: flufl.enum 4.0
I am happy to announce flufl.enum version 4.0. What is flufl.enum? It is an enumeration package with a simple syntax, and concise and specific semantics. flufl.enum is compatible with Python 2.7, 3.2, and 3.3. It is proposed for inclusion in Python 3.4 by way of PEP 435. My thanks to Eli Bendersky for his help with both the code and in authoring the PEP, as well as everyone who participated in discussions on python-dev, python-ideas, and at the PyCon 2013 language summit. Changes since 3.2: - Added the IntEnum variant. When you create an enumeration with this base class, the resulting enum values *are* ints and can be used anywhere a Python int can be used, including in the C API. (LP: #1132976) - make() is deprecated. You can now just call Enum() or IntEnum() to programmatically create enumerations. (LP: #1162375). These constructors now also accept a space-separated string of attribute names which are auto-split and auto-numbered. They also accept a dictionary mapping names to values. - IntEnums values support __index__() for slicing (LP: #1132972), as well as__int__() for coercion to a concrete integer. - EnumValue.__int__() is deprecated; use IntEnumValue (via IntEnum) instead. - EnumValues now have a .value attribute to access the actual, underlying value. (LP: #1132859) - Previously deprecated attributes .enumclass and .enumname have been removed, as well as the module function make_enum(). (LP: #1132951) - Minor API changes: the repr of enum values say "value=" instead of "int=", and multiple enum values in a single enum definition now raises ValueError instead of TypeError. - Single argument Enum() calling as a synonym for getitem is deprecated. - Other bugs fixed: LP: #1026403, LP: #1132830, LP: #1124596 Full documentation is available here: http://pythonhosted.org/flufl.enum/README.html The project home is at: https://launchpad.net/flufl.enum You can report bugs at: https://bugs.launchpad.net/flufl.enum Download the package from the Cheeseshop: https://pypi.python.org/pypi/flufl.enum or from the Launchpad project page above.

ANN: gcc-python-plugin 0.12
gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the CPython interpreter within GCC, allowing you to write new compiler warnings in Python, generate code visualizations, etc. It ships with "gcc-with-cpychecker", which implements static analysis passes for GCC aimed at finding bugs in CPython extensions. In particular, it can automatically detect reference-counting errors: http://gcc-python-plugin.readthedocs.org/en/latest/cpychecker.html Major new features in 0.12 == * support added for GCC 4.8 (along with 4.6 and 4.7) * addition of a new "gcc-c-api" component to isolate much of GCC's internals (and the differences between 4.6-4.8). I plan for this to eventually be its own project, aiming at providing a stable API and ABI for working with GCC, once it has proven itself in the context of the python plugin. * link-time-optimization support, for e.g. whole-program visualizations across multiple source files. See http://gcc-python-plugin.readthedocs.org/en/latest/0.12.html for more information, and for details of the numerous other changes. Tarball releases are available at: https://fedorahosted.org/releases/g/c/gcc-python-plugin/ Prebuilt-documentation can be seen at: http://gcc-python-plugin.readthedocs.org/en/latest/index.html The project's homepage is: https://fedorahosted.org/gcc-python-plugin/ The plugin and checker are Free Software, licensed under the GPLv3 or later.

gui2py alpha 0.9a: Simple and powerful GUI framework for agile development, released
FYI gui2py is a “fork” of PythonCard (a simple software construction kit based on wxpython), but improved trying to enhance it with a modern look & feel (better visual designer, property grid, drag & drop toolbox, etc.) and keeping it simple and powerful (i.e. adding MVC List, Tree, Grid, easier layout with Notebook, Sizers and Web-like features): https://code.google.com/p/gui2py/ It was based initially mainly on PythonCard (and also on wxPython Demo, wxGlade and other related projects), but also it includes a lot of experience and personal needs (it would be used to port a legacy ERP-like system for SME, actually composed of a large Visual Basic 5.0 classic codebase). For more info see: https://code.google.com/p/erplibre/ It is also aimed for teaching in introductory and intermediate programming courses (prior web development assignments), so it was simplified even further and adopted some HTML/Javascript features. In parallel, gui2py is part of a meta-project called rad2py (Rapid Application Development for Python), an academic research about software engineering best practices and quality assurance, whose goals are to integrate an IDE (code editor, debugger, unit test and other tools) with agile methodologies and a well defined software process (mainly for metrics collection, analysis and estimation): https://code.google.com/p/rad2py/ https://gui2py.googlecode.com/hg/screenshots/win8/rad2py_ide2py_gui2py_integration.png As gui2py it is not completely backwards compatible with PythonCard, a lot of code was changed/removed or added, it was "forked" in a separate project to not cause confusions. Migration should be easy, and an automatic tool is planned to convert PythonCard resources and source code to gui2py requeriments. New features are only available on gui2py, and they could not be backported to PythonCard. This alpha release is functional and "stable" for development porposes, but expect some APIs to change in the near future, and a lot of features still need to be incorporated.

ANN: Hy - Python / Lisp interoperability layer
Hello, World! tl;dr = Version: 0.9.4 License: Expat (sometimes called MIT) Hilarious: Yes Hy is a wicked funny hack that lets you interop (in both directions) with Lisp from Python (or with Python from Lisp). It's pip installable: $ pip install hy [...] $ hy => (print (.join ", " ["Hello" "World"])) Hello, World (REPL even has cute readline bits mostly workingish, with a few known issues) And the source is on GitHub @ http://git.io/hy (star it, fork it, hack it) It's undergoing changes quite quickly - so, be careful! OK, what is it (technically) Hy is a set of hacks, implemented in Python, to lex and compile a Lisp variant (called `Hy', which looks very similar to Clojure in some ways) into Python AST, and transparently load it into sys.modules using a PEP 302 import hook. I gave a lightning talk about Hy at PyCon, in case anyone's having flashbacks. You can see that talk on my blog (http://blog.pault.ag/post/46982895940/), or watch a full hour-long talk about Hy at Boston Python at http://www.youtube.com/watch?v=ulekCWvDFVI Right, so that means? = You can do hilarious (hylarious?) things like write full Django projects[1] in Lisp, or interop with pymongo[2], or even use pdb to debug Lisp code[3]. Wait, are you serious? == About it working? Yup! About making this lisp-variant production quality? Not really. It's just really funny, and helps teach people about how awesome Python is. Whatabout Macros? = Yep!(*) *: but you have to write them in Python for now (code plot'ed) :( Docs? = Yep! http://hy.rtfd.org/ - could use help! Hacks welcome!
