ANN: PyEnchant 1.2.0
by Ryan Kelly Sept. 19, 2007

Sept. 19, 2007

Hi All, I'm pleased to announce the release of PyEnchant version 1.2.0. This version includes some important updates in the underlying enchant library, and implements basic "filters" to allow skipping of email addresses, WikiWords, URLs, etc during a spellchecking session. Cheers, Ryan About: ------ Enchant (http://www.abisource.com/enchant/) is the spellchecking package behind the AbiWord word processor, is being considered for inclusion in the KDE office suite, and is proposed as a FreeDesktop.org standard. It's completely cross-platform because it wraps the native spellchecking engine to provide a uniform interface. PyEnchant brings this simple, powerful and flexible spellchecking engine to Python: http://pyenchant.sourceforge.net/ It also provides extended functionality including classes for tokenizing text and iterating over the spelling errors in it, as well as a ready-to-use text interface and wxPython dialog. Current Version: 1.2.0 Licence: LGPL with exemptions, as per Enchant itself ChangeLog for 1.2.0: -------------------- * Implemented "filters" that allow tokenization to skip common word forms such as URLs, WikiWords, email addresses etc. * Now ships with enchant-1.3.0, meaning: * PWLs can return a useful list of suggestions rather than the empty list * Hunspell replaces MySpell as the default Windows backend * Tokenization doesnt split words at non-alpha characters by default * GtkSpellCheckerDialog contributed by Fredrik Corneliusson * Removed deprecated functionality: * Dict.add_to_personal * All registry handling functionality from enchant.utils * enchant.utils.SpellChecker (use enchant.checker.SpellChecker) * Removed PyPWL, as native enchant PWLs can now suggest corrections -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.

Call for junior PEP editors
by Barry Warsaw April 30, 2007

April 30, 2007

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [reposted to python-announce] David Goodger and I have been the PEP editors for ages. Well, mostly David lately as I've been way too busy to be of much use. David is also pretty busy, and he lamented that he doesn't have much time for editing when he put out his call for PEPs earlier this month. We've now, or will soon have three more experienced Pythonistas helping out as PEP editors, Georg Brandl, Brett Cannon, and Anthony Baxter. As long as they've been hacking Python, you'd have thought they'd have learned their lesson by now, but we'll gladly consume more of their time and souls. David and I would like to see some junior Pythonistas join the PEP editor team, as a great way to gain experience and become more involved with the community. As David says, PEP editing is something a tech writer can do; it doesn't require intimate knowledge of Python's C code base for example. PEP editors don't judge the worthiness of a PEP -- that's for the Python community to do, but they do the important work of ensuring that the PEPs are up to the high quality and consistent standards that have been established over the years. A PEP editor is sometimes also involved in the meta process of developing and maintaining the PEPs. A good editor's eye, excellent written communication skills, and the inhuman amount of spare time that only the young have are your most important qualifications. If you're a budding Pythonista and are interested in becoming a PEP editor, please send an email to peps(a)python.org. Let us know about your writing and/or editing experience, how long you've been using Python, how long you've been programming in general, and how much cash you'll be sending our way. Kidding about that last bit. python- dev lurkers are encouraged to apply! Again, this call is for junior Pythonistas only. I think we have enough experienced people now to cover our bases and to help mentor new editors. We're really eager to get some new blood involved in the Python community. We may not accept all applicants; we're aiming for two or three additional editors, but that number isn't set in stone. Cheers, - -Barry (and David) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRjaBB3EjvBPtnXfVAQLVtgP+Ops7YFqsvHTKxVW7LSqBJuk1OK89lvcs 2hn6UYKzPXFpDOdGryLy7qoLfSs2U+IAOeajb0zfv6YeO1T3KXKgfytSOMiLA4/3 uAK1B86DNYySPGcBmoVx+ymm8drLpWsj3Yiw6wABiU97T/nEpUPPHGjCo+zrK/OA 9Z1UwuRSudI= =o55n -----END PGP SIGNATURE-----

Ann: Crunchy 0.8.2
by Johannes Woolard April 27, 2007

April 27, 2007

Crunchy 0.8.2 has been released, and as usual you can download it from http://code.google.com/p/crunchy Crunchy is an application that formats and delivers html-written Python tutorials inside a browser window, adding interactive elements and snazzy navigation. This is a minor release, with the only major change being an update of the vlam syntax. Since 0.8 support has also been added for Apple Macs, so Crunchy now officially supports Windows, OS X and Ubuntu Linux - and probably also works on every other UNIX platform out there. In the short to medium future we will be releasing a significant rewrite of crunchy, simplifying the developer interface and adding new features, significant highlights will include: * Better handling of IO from user scripts. * Graphics canvasses will be available everywhere, not just in canvas widgets. * A significantly simpler version of VLAM. * A new plugin architecture for Crunchy itself, making it easily extensible. * ... and maybe even support for Matplotlib. We hope you continue to enjoy Crunchy. André Roberge and Johannes Woolard.

bbfreeze 0.92.0
by Ralf Schmitt April 27, 2007

April 27, 2007

Hi all, I've just uploaded bbfreeze 0.92.0 to python's cheeseshop. bbfreeze creates standalone executables from python scripts. It's similar in functionality to py2exe or cx_Freeze. It offers the following features: easy installation bbfreeze can be installed with setuptools' easy_install command. binary dependency tracking bbfreeze will track binary dependencies and will include DLLs and shared libraries needed by a frozen program. multiple script freezing bbfreeze can freeze multiple scripts at once. python interpreter included bbfreeze will create an extra executable named 'py', which might be used like the python executable itself. bbfreeze works on windows and UNIX-like operating systems. It currently does not work on OS X. bbfreeze has been tested with python 2.4 and 2.5. bbfreeze will not work with python versions prior to 2.3 as it uses the zipimport feature introduced with python 2.3.

ANN: BList v 0.9.3, a list-like type with better asymptotic performance
by Daniel Stutzbach April 26, 2007

April 26, 2007

We're pleased to announce the first public release of BList (v 0.9.3), a list-like type with better asymptotic performance. The BList extension module is available via PyPi: http://www.python.org/pypi/blist The BList is a type that looks, acts, and quacks like a Python list(), but has better performance for many (but not all) use cases. Below are some of the unique features of the BList: - just as fast as a Python list() when the list is small - insertion or removal from the list takes O(log n) time - getslice runs in O(log n) time and uses O(log n) memory, regardless of slice size - making a shallow copy runs in O(1) time and uses O(1) memory - setslice runs in O(log n + log k) time if the inserted slice is a BList of length k - multipling a BList by k takes O(log k) time and O(log k) memory Example: >>> from blist import * >>> x = blist([0]) >>> x *= 2**29 >>> x.append(5) >>> y = x[4:-234234] >>> del x[3:1024] None of the above operations have a noticeable delay, even though the lists have over 500 million elements due to line 3. The BList has two key features that allow it to pull this off this performance: 1. Internally, a B+Tree is a wide, squat tree. Each node has a maximum of 128 children. If the entire list contains 128 or fewer objects, then there is only one node, which simply contains an array of the objects. In other words, for short lists, a BList works just like Python's array-based list() type. Thus, it has the same good performance on small lists. 2. The BList type features transparent copy-on-write. If a non-root node needs to be copied (as part of a getslice, copy, setslice, etc.), the node is shared between multiple parents instead of being copied. If it needs to be modified later, it will be copied at that time. This is completely behind-the-scenes; from the user's point of view, the BList works just like a regular Python list. So you can see the performance of the BList in more detail, several performance graphs available at the following link: http://stutzbachenterprises.com/blist/ Feedback -------- We're eager to hear about your experiences with the BList. Please send all feedback and bug reports to daniel(a)stutzbachenterprises.com.
