Hi all, On the behalf of Spyder's development team (http://code.google.com/p/spyderlib/people/list), I'm pleased to announce that Spyder v2.1.2 has been released and is available for Windows XP/Vista/7, GNU/Linux and MacOS X: http://code.google.com/p/spyderlib/ As this is mostly a maintenance release, a lot of bugs were fixed and some minor features were added: http://code.google.com/p/spyderlib/wiki/ChangeLog Spyder is a free, open-source (MIT license) interactive development environment for the Python language with advanced editing, interactive testing, debugging and introspection features. Originally designed to provide MATLAB-like features (integrated help, interactive console, variable explorer with GUI-based editors for dictionaries, NumPy arrays, ...), it is strongly oriented towards scientific computing and software development. Thanks to the `spyderlib` library, Spyder also provides powerful ready-to-use widgets: embedded Python console (example: http://packages.python.org/guiqwt/_images/sift3.png), NumPy array editor (example: http://packages.python.org/guiqwt/_images/sift2.png), dictionary editor, source code editor, etc. Description of key features with tasty screenshots can be found at: http://code.google.com/p/spyderlib/wiki/Features On Windows platforms, Spyder is also available as a stand-alone executable (don't forget to disable UAC on Vista/7). This all-in-one portable version is still experimental (for example, it does not embed sphinx -- meaning no rich text mode for the object inspector) but it should provide a working version of Spyder for Windows platforms without having to install anything else (except Python 2.x itself, of course). Don't forget to follow Spyder updates/news: * on the project website: http://code.google.com/p/spyderlib/ * and on our official blog: http://spyder-ide.blogspot.com/ Last, but not least, we welcome any contribution that helps making Spyder an efficient scientific development/computing environment. Join us to help creating your favourite environment! (http://code.google.com/p/spyderlib/wiki/NoteForContributors) Enjoy! -Pierre

[ANN]Uliweb 0.0.1a7 release!

by limodou

[uliweb] download: http://uliweb.googlecode.com/files/Uliweb-0.0.1a7.zip project: http://code.google.com/p/uliweb https://github.com/limodou/uliweb [plugs] also plugs is a uliweb app collection project, and you can use it download: http://plugs.googlecode.com/files/plugs-0.0.1b2.zip project: http://code.google.com/p/plugs/ https://github.com/limodou/plugs About Uliweb---------------- Uliweb is a Python based web framework. This project was created and lead by Limodou <limodou(a)gmail.com>. License------------ Uliweb is released under BSD license. Infrastructure---------------- Uliweb was not created totally from scratch. It uses some modules created by other developers, for example: * Werkzeug Used to handle core processes in the framework. For example: command line tools , URL Mapping, Debug, etc.* SqlAlchemy The ORM based on it. Developers can access databases, or use the module separately. I also referenced some code from other web frameworks, for example: * The Templating system is styled after the one used in web2py several improvements were made. I also constructed a few new "wheels" myself. For example: * Form processing module. Developers can use it to create HTML code, validate submitted data and convert submitted data to Python data types.* I18n processing including template support, language lazy process.* Uliorm, which is an ORM module, was built on top of SqlAlchemy. I also referenced from GAE datastore module.* Framework runtime process.* Plugin mechanism, styled after the one used in the UliPad project. Features----------- * Organization * MVT(Model View Template) development model. * App-based project structure. 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. And now, Uliweb also support Class View style. I hope you can enjoy it. * 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 * Create app, 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. * Startup a development web server thats supports debugging and autoreload. * Deployment * Supports easy deployment on the GAE platform. * Supports mod_wsgi, cgi, fast_cgi, scgi, uwsgi. * Development Provide a development server, and can be automatically reload when some module files are modified. * Misc. Various demos are available for anyone interested in learning more about Uliweb. It includes all core codes and also all source code of uliwebproject , and some other demo codes, which can be used directly/freely as you wish. * static file serving support. Uliweb supports static file access directly, and it can also process HTTP_IF_MODIFIED_SINCE and return static file content in trunk. Principle---------- * Simple and easy to use web framework.* Reusability and configurable are the main ideas about Uliweb.* The web framework should be flexiable and easy to extend. Links-------- * Plugs is a Uliweb apps collection project, you can visit it at https://github.com/limodou/plugs* uliweb-doc is a documentation project of Uliweb, you can visit it at https://github.com/limodou/uliweb-doc, and you can also read the compiled documentation at http://uliweb.rtfd.org* uliwebzone is a community project of Uliweb, you can visit it at https://github.com/limodou/uliwebzone, and you can also see online demo which hosted in dotcloud http://www.uliweb.dotcloud.com/. -- I like python!

ANN: SciPy 0.10.0 released

by Ralf Gommers

Hi all, I am pleased to announce the availability of SciPy 0.10.0. For this release over a 100 tickets and pull requests have been closed, and many new features have been added. Some of the highlights are: - support for Bento as a build system for scipy - generalized and shift-invert eigenvalue problems in sparse.linalg - addition of discrete-time linear systems in the signal module Sources and binaries can be found at , release notes are copied below. Enjoy, The SciPy developers ========================== SciPy 0.10.0 Release Notes ========================== .. contents:: SciPy 0.10.0 is the culmination of 8 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a limited number of deprecations and backwards-incompatible changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Moreover, our development attention will now shift to bug-fix releases on the 0.10.x branch, and on adding new features on the development master branch. Release highlights: - Support for Bento as optional build system. - Support for generalized eigenvalue problems, and all shift-invert modes available in ARPACK. This release requires Python 2.4-2.7 or 3.1- and NumPy 1.5 or greater. New features ============ Bento: new optional build system -------------------------------- Scipy can now be built with `Bento <http://cournape.github.com/Bento/>`_. Bento has some nice features like parallel builds and partial rebuilds, that are not possible with the default build system (distutils). For usage instructions see BENTO_BUILD.txt in the scipy top-level directory. Currently Scipy has three build systems, distutils, numscons and bento. Numscons is deprecated and is planned and will likely be removed in the next release. Generalized and shift-invert eigenvalue problems in ``scipy.sparse.linalg`` --------------------------------------------------------------------------- The sparse eigenvalue problem solver functions ``scipy.sparse.eigs/eigh`` now support generalized eigenvalue problems, and all shift-invert modes available in ARPACK. Discrete-Time Linear Systems (``scipy.signal``) ----------------------------------------------- Support for simulating discrete-time linear systems, including ``scipy.signal.dlsim``, ``scipy.signal.dimpulse``, and ``scipy.signal.dstep``, has been added to SciPy. Conversion of linear systems from continuous-time to discrete-time representations is also present via the ``scipy.signal.cont2discrete`` function. Enhancements to ``scipy.signal`` -------------------------------- A Lomb-Scargle periodogram can now be computed with the new function ``scipy.signal.lombscargle``. The forward-backward filter function ``scipy.signal.filtfilt`` can now filter the data in a given axis of an n-dimensional numpy array. (Previously it only handled a 1-dimensional array.) Options have been added to allow more control over how the data is extended before filtering. FIR filter design with ``scipy.signal.firwin2`` now has options to create filters of type III (zero at zero and Nyquist frequencies) and IV (zero at zero frequency). Additional decomposition options (``scipy.linalg``) --------------------------------------------------- A sort keyword has been added to the Schur decomposition routine (``scipy.linalg.schur``) to allow the sorting of eigenvalues in the resultant Schur form. Additional special matrices (``scipy.linalg``) ---------------------------------------------- The functions ``hilbert`` and ``invhilbert`` were added to ``scipy.linalg``. Enhancements to ``scipy.stats`` ------------------------------- * The *one-sided form* of Fisher's exact test is now also implemented in ``stats.fisher_exact``. * The function ``stats.chi2_contingency`` for computing the chi-square test of independence of factors in a contingency table has been added, along with the related utility functions ``stats.contingency.margins`` and ``stats.contingency.expected_freq``. Basic support for Harwell-Boeing file format for sparse matrices ---------------------------------------------------------------- Both read and write are support through a simple function-based API, as well as a more complete API to control number format. The functions may be found in scipy.sparse.io. The following features are supported: * Read and write sparse matrices in the CSC format * Only real, symmetric, assembled matrix are supported (RUA format) Deprecated features =================== ``scipy.maxentropy`` -------------------- The maxentropy module is unmaintained, rarely used and has not been functioning well for several releases. Therefore it has been deprecated for this release, and will be removed for scipy 0.11. Logistic regression in scikits.learn is a good alternative for this functionality. The ``scipy.maxentropy.logsumexp`` function has been moved to ``scipy.misc``. ``scipy.lib.blas`` ------------------ There are similar BLAS wrappers in ``scipy.linalg`` and ``scipy.lib``. These have now been consolidated as ``scipy.linalg.blas``, and ``scipy.lib.blas`` is deprecated. Numscons build system --------------------- The numscons build system is being replaced by Bento, and will be removed in one of the next scipy releases. Backwards-incompatible changes ============================== The deprecated name `invnorm` was removed from ``scipy.stats.distributions``, this distribution is available as `invgauss`. The following deprecated nonlinear solvers from ``scipy.optimize`` have been removed:: - ``broyden_modified`` (bad performance) - ``broyden1_modified`` (bad performance) - ``broyden_generalized`` (equivalent to ``anderson``) - ``anderson2`` (equivalent to ``anderson``) - ``broyden3`` (obsoleted by new limited-memory broyden methods) - ``vackar`` (renamed to ``diagbroyden``) Other changes ============= ``scipy.constants`` has been updated with the CODATA 2010 constants. ``__all__`` dicts have been added to all modules, which has cleaned up the namespaces (particularly useful for interactive work). An API section has been added to the documentation, giving recommended import guidelines and specifying which submodules are public and which aren't. Authors ======= This release contains work by the following people (contributed at least one patch to this release, names in alphabetical order): * Jeff Armstrong + * Matthew Brett * Lars Buitinck + * David Cournapeau * FI$H 2000 + * Michael McNeil Forbes + * Matty G + * Christoph Gohlke * Ralf Gommers * Yaroslav Halchenko * Charles Harris * Thouis (Ray) Jones + * Chris Jordan-Squire + * Robert Kern * Chris Lasher + * Wes McKinney + * Travis Oliphant * Fabian Pedregosa * Josef Perktold * Thomas Robitaille + * Pim Schellart + * Anthony Scopatz + * Skipper Seabold + * Fazlul Shahriar + * David Simcha + * Scott Sinclair + * Andrey Smirnov + * Collin RM Stocks + * Martin Teichmann + * Jake Vanderplas + * Gaël Varoquaux + * Pauli Virtanen * Stefan van der Walt * Warren Weckesser * Mark Wiebe + A total of 35 people contributed to this release. People with a "+" by their names contributed a patch for the first time.

CaptureMock 0.3 - true record/replay mocking for Python (and other things...)

by Geoff Bache

Hi all, There's a new release of CaptureMock out. For Python users the main enhancement/fix is that you can now inherit from classes that are intercepted while not intercepting your derived class itself (if you follow that). Regards, Geoff Bache More detail: CaptureMock is a tool for creating mocks via a "true" capture-replay style approach. It records interactions to a separate file which can then be used for replay in future runs. It is thus not another "EasyMock" clone. Interaction can be recaptured from a real system at any point, and no mock code needs to be written. It handles Python calls, command-line programs, and synchronous messaging over networks. Custom clients can now also be written for any language. Website: http://www.texttest.org/index.php?page=capturemock Mailing list: https://lists.sourceforge.net/lists/listinfo/texttest-users

tox-1.2: some bug fixes for the virtualenv-based generic test runner

by holger krekel

tox 1.2: the virtualenv-based test run automatizer =========================================================================== I am happy to announce tox 1.2, now using and depending on the latest virtualenv code and containing some bug fixes. TOX automates tedious test activities driven from a simple ``tox.ini`` file, including: * creation and management of different virtualenv environments with different Python interpreters * packaging and installing your package into each of them * running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks * testing dev packages against each other without needing to upload to PyPI It works well on virtually all Python interpreters that support virtualenv. Docs and examples are at: http://tox.testrun.org Installation: pip install -U tox code hosting and issue tracking on bitbucket: http://bitbucket.org/hpk42/tox best, Holger Krekel 1.2 compared to 1.1 --------------------- - remove the virtualenv.py that was distributed with tox and depend on virtualenv-1.6.4 (possible now since the latter fixes a few bugs that the inling tried to work around) - fix issue10: work around UnicodeDecodeError when inokving pip (thanks Marc Abramowitz) - fix a problem with parsing {posargs} in tox commands (spotted by goodwill) - fix the warning check for commands to be installed in testevironment (thanks Michael Foord for reporting)
