pyPEG 2.15 released
by Volker Birk 10 Jan '14

10 Jan '14

pyPEG now supports adding feeble things to the AST like automatically removed comments or whitespace. pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG like language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML. pyPEG implements an intrinsic Packrat parser. Memoization is used for performance improvements. pyPEG is used by defining a data model with a grammar. Therefore it cannot only be used to parse text, but to compose text out of the language model, too. It can be used for code generation. You can find pyPEG2 in the PyPI repository. The homepage is here: <http://fdik.org/pyPEG>. pyPEG is maintained in a Bitbucket repository at <https://bitbucket.org/fdik/pypeg/>. Yours, VB. -- "Back when PHP had less than 100 functions and the function hashing mechanism was strlen(). In order to get a nice hash distribution of function names across the various function name lengths names were picked specifically to make them fit into a specific length bucket." (Rasmus Lerdorf)

[RELEASED] Python 3.4.0b2
by Larry Hastings 05 Jan '14

05 Jan '14

On behalf of the Python development team, I'm pleased to announce the second beta release of Python 3.4. This is a preview release, and its use is not recommended for production settings. Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Major new features and changes in the 3.4 release series include: * PEP 428, a "pathlib" module providing object-oriented filesystem paths * PEP 435, a standardized "enum" module * PEP 436, a build enhancement that will help generate introspection information for builtins * PEP 442, improved semantics for object finalization * PEP 443, adding single-dispatch generic functions to the standard library * PEP 445, a new C API for implementing custom memory allocators * PEP 446, changing file descriptors to not be inherited by default in subprocesses * PEP 450, a new "statistics" module * PEP 451, standardizing module metadata for Python's module import system * PEP 453, a bundled installer for the *pip* package manager * PEP 454, a new "tracemalloc" module for tracing Python memory allocations * PEP 456, a new hash algorithm for Python strings and binary data * PEP 3154, a new and improved protocol for pickled objects * PEP 3156, a new "asyncio" module, a new framework for asynchronous I/O Python 3.4 is now in "feature freeze", meaning that no new features will be added. The final release is projected for late February 2014. To download Python 3.4.0b2 visit: http://www.python.org/download/releases/3.4.0/ Please consider trying Python 3.4.0b2 with your code and reporting any new issues you notice to: http://bugs.python.org/ Enjoy! -- Larry Hastings, Release Manager larry at hastings.org (on behalf of the entire python-dev team and 3.4's contributors)

[RELEASED] six 1.5.0
by Benjamin Peterson 05 Jan '14

05 Jan '14

I'm happy to announce the immediate release of six 1.5.0. six is a Python 2/3 compatibility library designed to aid the same-source migration path. The new release can be downloaded on PyPI: https://pypi.python.org/pypi/six six.moves has been improved to act more like real modules. You should be able to import directly classes and functions from six.moves Python 2.4 support has been dropped as of this release. This is because py.test stopped supporting 2.4. I'd particularly like to thank Marc Abramowitz and Alexander Lukanin for contributing patches. Report bugs to https://bitbucket.org/gutworth/six Here is the complete changelog: - Removed support for Python 2.4. This is because py.test no longer supports 2.4. - Fix various import problems including issues #19 and #41. six.moves modules are now lazy wrappers over the underlying modules instead of the actual modules themselves. - Issue #49: Add six.moves mapping for tkinter.ttk. - Pull request #24: Add __dir__ special method to six.moves modules. - Issue #47: Fix add_metaclass on classes with a string for the __slots__ variable. - Issue #44: Fix interpretation of backslashes on Python 2 in the u() function. - Pull request #21: Add import mapping for urllib's proxy_bypass function. - Issue #43: Add import mapping for the Python 2 xmlrpclib module. - Issue #39: Add import mapping for the Python 2 thread module. - Issue #40: Add import mapping for the Python 2 gdbm module. - Issue #35: On Python versions less than 2.7, print_ now encodes unicode strings when outputing to standard streams. (Python 2.7 handles this automatically.) -- Regards, Benjamin

[ANN]Uliweb 0.2.3 released!
by limodou 05 Jan '14

05 Jan '14

## About Uliweb Uliweb is a full-stacked Python based web framework. It has three main design goals, they are: reusability, configurability, and replaceability. All the functionalities revolve around these goals. This project was created and lead by Limodou <mailto:limodou@gmail.com>. ## License Uliweb is released under BSD license. ## Change Log * Update nginx support output, add proxy_set_header * Add `save_file()` function to orm, so you can save select result to a csv file * Add `save_file()` method to Result. * Fix missing `clear()` function of SortedDict. * Fix i18n process, for project and apps extraction, it'll create application first, so that user defined tag will be registered correctly. But user defined tag will be limited later. * Add `walk_dirs()` to utils/common.py. This function can ignore some files and file ext, and supports fnmatch pattern. ## Features * Project Organization * MVT(Model View Template) development model. * Distributed development but unified management. Uliweb organizes a project with small apps. Each app can have its own configuration file(settings.ini), template directory, and static directory. Existing apps can be easily reused, but are treated as a compound. web application project if configured as such. Developers can also reference static files and templates between apps, thus easing inter-application data exchange. All apps in a project are loaded by default if INSTALLED_APPS is not configured in the configuration file. All separate app configuration files are automatically processed at project startup. * URL Mapping * Flexiable and powerful URL mapping. Uliweb uses werkzeug's routing module. User can easily define a URL, which in turn can be easily bound with a view function. URLs can also be created reversely according to the view function name. It supports argument definitions in URLs and default URL mapping to a view function. * View and Template * View templates can be automatically applied. If you return a dict variable from view function, Uliweb will automatically try to match and apply a template according to the view function name. * Environment execution mode. Each view function will be run in an environment, which eliminates the need to write many import statements. Plus there are already many objects that can be used directly, for example: request, response, etc. This is DRY and saves a lot of coding * Developers can directly use Python code in a template, the Python code does not neede to be indented as long as a pass statement is added at the end of each code block. Uliweb also supports child template inclusion and inheritance. * ORM * Uliorm is the default ORM module but not configured by default. Developers are free to use any ORM module as preferred. * Uliorm supports model creation and automatic database migiration(table creation and table structure modification). * I18n * Can be used in python and template files. * Browser language and cookie settings are supported including automatic language switching. * Provides a command line tool that developers can use to extract .po files. This can happen either at the app level or project level process. It can automatically merge .pot files to existing .po files. * Extension * Dispatch extension. This is a dispatch processing mechanism that utilizes different types of dispatch points. So you can write procedures to carry out special processes and bind them to these dispatch points. For example, database initicalization, I18n process initialization, etc. * middleware extension. It's similar to Djangos. You can configure it in configuration files. Each middleware can process the request and response objets. * Special function calls in the views module initial process. If you write a special function named __begin__, it'll be processed before any view function can be processed, this allows developers to do some module level processing at that point, for example: check the user authentication, etc. * Command Line Tools * Creates project, creates apps, and include the basic essential directory structure, files and code. * Export static files, you can export all available apps' static files to a special directory. Also supports css and js combinition and compress process. * Startup a development web server thats supports debugging and autoreload. * Apps can also have its own command line tools. For example: orm, auth, etc. * Deployment * Supports mod_wsgi in Apache. * Supports uwsgi. * Development * Provide a development server, and can be automatically reload when some module files are modified. * Enhanced debugging, you can check the error traceback, template debugging is also supported. ## Commuity * Mailing List: http://groups.google.com/group/uliweb ## Links * **Uliweb** Project Homepage https://github.com/limodou/uliweb * **Uliweb-doc** Documentation Project http://github.com/limodou/uliweb-doc * **Uliweb-doc Online** Document http://limodou.github.com/uliweb-doc/ * **plugs** Uliweb Apps Collection Project https://github.com/limodou/plugs -- I like python!
