[ANN] PyLint 0.9
by Sylvain Thénault Jan. 10, 2006

Jan. 10, 2006

Hi ! I'm very pleased to announce the new 0.9 release of PyLint. This release provides a lot of bug fixes and some new checks and other minor changes. This release depends on the latest astng and logilab-common release (i.e. 0.14 and 0.13 respectivly), so install them before this one. The good news is that the new astng inference capabilities should allow to add powerful checks to pylint in a new future :o) What's new ? ------------ 2006-01-10 -- 0.9.0 * a lot of updates to follow astng 0.14 API changes, so install logilab-astng 0.14 or greater before using this version of pylint * checker number 10 ! newstyle will search for problems regarding old style / new style classes usage problems (rely on astng 0.14 new style detection feature) * new 'load-plugins' options to load additional pylint plugins (usable from the command line or from a configuration file) (implements #10031) * check if a "pylintrc" file exists in the current working directory before using the one specified in the PYLINTRC environment variable or the default ~/.pylintrc or /etc/pylintrc * fixed W0706 (Identifier used to raise an exception is assigned...) false positive and reraising a catched exception instance * fixed E0611 (No name get in module blabla) false positive when accessing to a class'__dict__ * fixed some E0203 ("access to member before its definition") false positive * fixed E0214 ("metaclass method frist argument should be mcs) false positive with staticmethod used on a metaclass * fixed packaging which was missing the test/regrtest_data directory * W0212 (method could be a function) has been reclassified in the REFACTOR category as R0201, and is no more considerer when a method overrides an abstract method from an ancestor class * include module name in W0401 (wildcard import), as suggested by Amaury * when using the '--parseable', path are written relative to the current working directory if in a sub-directory of it (#9789) * 'pylint --version' shows logilab-astng and logilab-common versions * fixed pylint.el to handle space in file names * misc lint style fixes What is pylint ? ---------------- Pylint is a python tool that checks if a module satisfy a coding standard. Pylint can be seen as another pychecker since nearly all tests you can do with pychecker can also be done with Pylint. But Pylint offers some more features, like checking line-code's length, checking if variable names are well-formed according to your coding standard, or checking if declared interfaces are truly implemented, and much more (see http://www.logilab.org/projects/pylint/ for the complete check list). The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature. The usage it quite simple : $ pylint mypackage.mymodule This command will output all the errors and warnings related to the tested code (here : mypackage.mymodule), will dump a little summary at the end, and will give a mark to the tested code. Pylint is free software distributed under the GNU Public Licence.

[ANN] astng 0.14
by Sylvain Thénault Jan. 10, 2006

Jan. 10, 2006

Hi ! I'm pleased to announce the new 0.14 version of astng. This release mainly provides some major internal and api changes to have a richer model and a start for static inference on ast nodes. What's new ? ------------ * some major inference improvments and refactoring ! The drawback is the introduction of some non backward compatible change in the API but it's imho much cleaner and powerful now :) * new boolean property .newstyle on Class nodes (implements #10073) * new .import_module method on Module node to help in .resolve refactoring * .instance_attrs has list of assignments to instance attribute dictionary as value instead of one * added missing GenExprIf and GenExprInner nodes, and implements as_string for each generator expression related nodes * specifically catch KeyboardInterrupt to reraise it in some places * fix so that module names are always absolute * fix .resolve on package where a subpackage is imported in the __init__ file * fix a bug regarding construction of Function node from living object with realier version of python 2.4 * fix a NameError on Import and From self_resolve method * fix a bug occuring when building an astng from a living object with a property * lint fixes What is astng ? --------------- The aim of this module is to provide a common base representation of python source code for projects such as pychecker, pyreverse, pylint... Well, actually the development of this library is essentialy governed by pylint's needs. It extends class defined in the compiler.ast [1] module with some additional methods and attributes. Instance attributes are added by a builder object, which can either generate extended ast (let's call them astng ;) by visiting an existant ast tree or by inspecting living object. Methods are added by monkey patching ast classes.

Hi ! I'm pleased to announce the 0.13 new release of the logilab-common package. This release provides some bug fixes and minor enhancements and api changes which shouldn't break backward compatibility, so users are strongly encouraged to update. What's new ? ------------ * testlib: ability to skip a test * configuration: - cleaner configuration file generation - refactoring so that we can have more control on file configuration loading using read_config_file and load_config_file instead of load_file_configuration * modutils: fix is_relative to return False when from_file is a file located somewhere in sys.path * compat: make set iterable and support more other set operations... * removed the astng sub-package, since it's now self-distributed as logilab-astng What is logilab-common ? ------------------------ logilab-common is a collection of low-level Python packages and modules, designed to ease: * handling command line options and configuration files * writing interactive command line tools * manipulation files and character strings * interfacing to OmniORB * generating of SQL queries * running unit tests * manipulating tree structures * accessing RDBMS (currently postgreSQL and mysql) * generating text and HTML reports * logging Home page --------- http://www.logilab.org/projects/common Download -------- ftp://ftp.logilab.org/pub/common Mailing list ------------ mailto://python-projects@lists.logilab.org LOGILAB provides services in the fields of XML techniques and advanced computing (implementation of intelligent agents, knowledge management, natural language processing, statistical analysis, data mining, etc.), and also trainings on Python, XML, UML, Object Oriented design, design patterns use and other cutting edge topics.

IPython 0.7.0 is out.
by Fernando Perez Jan. 10, 2006

Jan. 10, 2006

Hi all, After a long hiatus (0.6.15 was out in June of 2005), I'm glad to announce the release of IPython 0.7.0, with lots of new features. WHAT is IPython? ---------------- 1. An interactive shell superior to Python's default. IPython has many features for object introspection, system shell access, and its own special command system for adding functionality when working interactively. 2. An embeddable, ready to use interpreter for your own programs. IPython can be started with a single call from inside another program, providing access to the current namespace. 3. A flexible framework which can be used as the base environment for other systems with Python as the underlying language. 4. A shell for interactive usage of threaded graphical toolkits. IPython has support for interactive, non-blocking control of GTK, Qt and WX applications via special threading flags. The normal Python shell can only do this for Tkinter applications. WHERE to get it? ---------------- IPython's homepage is at: http://ipython.scipy.org and downloads are at: http://ipython.scipy.org/dist I've provided: - source downloads (.tar.gz) - RPMs (for Python 2.3 and 2.4, built under Fedora Core 3). - Python Eggs (http://peak.telecommunity.com/DevCenter/PythonEggs). - a native win32 installer for both Python 2.3 and 2.4. Fedora users should note that IPython is now officially part of the Extras repository, so they can get the update from there as well (though it may lag by a few days). Debian, Fink and BSD packages for this version should be coming soon, as the respective maintainers (many thanks to Jack Moffit, Norbert Tretkowski, Andrea Riciputi and Dryice Liu) have the time to follow their packaging procedures. A lot of new features have gone into this release, the bulk of which were driven by user feedback and requests, and more importantly by patches from IPython users. I greatly appreciate these contributions, and hope they will continue in the future. In particular, thanks to Vivian de Smedt, Jorgen Stenarsson and Ville Vainio, who contributed large patches with much of the new significant functionality. I've tried to provide credit in the notes below and the project's ChangeLog, please let me know if I've accidentally ommitted you. Many thanks to Enthought for their continued hosting support for IPython. Release notes ------------- *** WARNING: compatibility changes *** - IPython now requires at least Python 2.3. If you can't upgrade from 2.2, you'll need to continue using IPython 0.6.15. *** End warning. As always, the NEWS file can be found at http://ipython.scipy.org/NEWS, and the full ChangeLog at http://ipython.scipy.org/ChangeLog. The highlights of this release follow. - Wildcard patterns in searches, supported by the %psearch magic, as well as the '?' operator. Type psearch? for the full details. Extremely useful, thanks to Jörgen Stenarson. - Major improvements to the pdb mode. It now has tab-completion, syntax highlighting and better stack handling. Thanks to Vivian De Smedt for this work (double-points given that pdb has a well-deserved reputation for being very unpleasant to work with). - Support for input with empty lines. If you have auto-indent on, this means that you need to either hit enter _twice_, or add/remove a space to your last blank line, to indicate you're done entering input. These changes also allow us to provide copy/paste of code with blank lines. - Support for pasting multiline input even with autoindent on. The code will look wrong on screen, but it will be stored and executed correctly internally. - TAB on an otherwise empty line actually inserts a tab. Convenient for indenting (for those who don't use autoindent). - Significant improvements for all multithreaded versions of ipython. Now, if your threaded code raises exceptions, instead of seeing a crash report, a normal (colored, verbose, etc.) exception is printed. Additionally, if you have pdb on, it will activate in your threaded code. Very nice for interactively debugging GUI programs. - Many fixes to embedded ipython, including proper handling of globals and tab completion. - New -t and -o options to %logstart, to respectively put timestamps in your logs, and to also log all output (tagged as #[Out]#). The default log name is now ipython_log.py, to better reflect that logs remain valid Python source. - Lightweight persistence mechanism via %store. IPython had always had %save, to write out a group of input lines directly to a file. Now, its %store companion stores persistently (associated with your profile, and auto-loaded at startup) not just source, but any python variable which can be pickled. Thanks to Matt Wilkie for the request, and ville for the patches. - Macros (created with %macro) can now be edited with %edit (just say '%edit macroname'). This, coupled with the ability to store them persistently, makes the macro system much more useful. - New guarantee that, if you disable autocalling, ipython will never call getattr() on your objects. This solves problems with code that has side-effects on attribute access. Note that TAB-completion inevitably does call getattr(), so not all forms of side-effects can be eliminated. - Unicode support for prompts. - Improvements to path handling under win32. Thanks to Ville and Jorgen for the patches. - Improvements to pager under win32. Contributed by Alexander Belchenko. - Demo class for interactive demos using ipython. - %pycat magic for showing syntax-highlighted python sources - support for download_url in setup.py, so PyPI (and setuptools) work transparently with ipython. - New exit/quit magics to exit, conditionally asking (%Exit/%Quit don't) - Automatically reopen the editor if your file has a syntax error in it (when using the %edit system). - New notation N-M for indicating the range of lines N,...,M (including both endpoints), in magic commands such as %macro, %save and %edit. - The IPython instance has a new attribute, .meta, which is an empty namespace (an instance of 'class Bunch:pass'). This is meant to provide extension writers with a safe namespace to store metadata of any kind, without the risk of name clashes with IPython's internals. - Added tab-completion support for objects with Traits, a sophisticated type definition system for Python: http://code.enthought.com/traits. - Several patches related to Emacs support. Thanks to Alex Schmolck and John Barnard. - New 'smart' autocall mode, which avoids autocalling if a function with no arguments is the input. The old 'full' mode can be obtained by setting the autocall parameter in the ipythonrc to 2, or via the %autocall magic. - A large amount of internal reorganization and cleanup, to allow the code to be more readily moved over to the chainsaw branch (see below). - Many other small fixes and enhancements. The changelog has full details. Enjoy, and as usual please report any problems on the IPython lists. Regards, Fernando.

by Felix Wiemann Jan. 9, 2006

Jan. 9, 2006

======================= Docutils 0.4 Released ======================= Docutils 0.4 has been released. You can download it from <http://prdownloads.sf.net/docutils/docutils-0.4.tar.gz?download>. What Is Docutils? ================= Docutils is a system for processing plaintext documentation into various useful formats, such as HTML or LaTeX. It includes reStructuredText, the easy to read, easy to use, what-you-see-is-what-you-get plaintext markup language. Major Changes Since The Previous Release (0.3.9) ================================================ * Added an S5/HTML writer and the rst2s5.py front end: multi-platform, multi-browser HTML slide shows. See <http://docutils.sf.net/docs/user/slide-shows.html> and <http://docutils.sf.net/docs/user/tools.html#rst2s5-py>. * The newlatex2e writer is nearing completion. * Added a DocTree reader, ``publish_doctree`` and ``publish_from_doctree`` convenience functions, for document tree extraction and reprocessing. * Added directives: "container" (generic block-level container), "default-role" (role used for `backtick` syntax), "title" (document title metadata), and "date" (generate the current local date, for substitution definitions). See <http://docutils.sf.net/docs/ref/rst/directives.html>. * Length units are now supported for image sizes; see <http://docutils.sf.net/docs/ref/rst/directives.html#image>. * Added standard definition files for special characters etc.; see <http://docutils.sf.net/docs/ref/rst/definitions.html>. * Added Japanese and Simplified Chinese language mappings, and support for double-width CJK-characters in tables and section titles. * Added a guide for distributors (http://docutils.sf.net/docs/dev/distributing.html) and a guide for developers (http://docutils.sf.net/docs/dev/hacking.html). * Added significant Emacs support for reST; see <http://docutils.sf.net/docs/user/emacs.html>. * Added a --strip-comments option; see <http://docutils.sf.net/docs/user/config.html#strip-comments>. * --embed-stylesheet is now the default for the HTML writer (rather than --link-stylesheet). Compatibility Note ================== Docutils 0.4.x is the last version that will support Python 2.1. Docutils 0.5 will *not* be compatible with Python 2.1; Python 2.2 or later will be required. Docutils 0.4.x is the last version that will make compromises in its HTML output for Netscape Navigator 4. Docutils 0.5 will require more up-to-date browsers (the exact definition is to be determined). -- Felix Wiemann -- http://www.ososo.de/

[ANN] Vision Egg 1.0 release
by Andrew Straw Jan. 9, 2006

Jan. 9, 2006

I am pleased to announce the Vision Egg 1.0, a free, open source software library for producing visual stimuli for use in vision research experiments. Please visit our website at http://www.visionegg.org = What is the Vision Egg? = The Vision Egg is based on OpenGL, enabling hardware-accelerated drawing on Windows, Mac OS X, linux, and other operating systems. It is capable of generating many stimuli in realtime, enabling closed-loop and gaze-contingent experiments. The library can utilize 3D projection geometry so that wide-field stimuli such as sinusoidal gratings or panoramic images may be specified in angular units and appropriately distorted for flat or other displays. The library comes with numerous demonstration programs which provide a 'hands-on' way to learn its capabilities. The Vision Egg is written in the Python computer language utilizing several third party modules, all of which are free, open source software. Additional software is available, such as a Python implementation of the popular QUEST Bayesian adaptive psychometric method by Watson and Pelli and Pylink, an interface for the EyeLink eyetrackers from SR Research. = What is new in this release? = Release 1.0 comes after 2 years of beta-testing by laboratories around the world. Since the release of version 0.9.9, the following changes have been made: * Major enhancements to the ephys server/GUI code to use normal (or slightly modified) demo scripts in this environment were done by Imran Ali and Lachlan Dowd in the lab of David O'Carroll at the University of Adelaide. * An initial patch for stereo support sent by Yuichi Sakano and Kevin J. MacKenzie at York University. * Parallel port enhancements by Hubertus Becker, University of Tübingen. * Arrow and FilledCircle stimuli by Hubertus Becker, University of Tübingen. * DaqKeyboard and ResponseControl by Hubertus Becker, University of Tübingen. * Full screen anti-aliasing support (FSAA) by Mark Halko, Boston University. * Various patches by Tony Arkles (University of Saskatchewan), including a suggestion to separate camera motions from the GL_PROJECTION matrix and put them in the GL_MODELVIEW matrix, where they belong. * Patch for VISIONEGG_SYSTEM_DIR by Nick Knouf, MIT. * Added win32_vretrace.WaitForRetrace() (but it's not used for much, yet) * Enhancements to EPhys Server/GUI sequencer * Added 'lat-long rectangle' to available 3D masking windows * Moved controller.CONSTANTS into FlowControl module namespace * Numerous bugfixes For further information, or to download the Vision Egg, visit http://www.visionegg.org

by Ian Bicking Jan. 9, 2006

Jan. 9, 2006

I'm pleased to announce the 0.4 release of the Paste Suite: Paste core, Script, Deploy, and WebKit. Locations --------- Web: http://pythonpaste.org Download: http://cheeseshop.python.org/pypi/Paste http://cheeseshop.python.org/pypi/PasteScript http://cheeseshop.python.org/pypi/PasteDeploy http://cheeseshop.python.org/pypi/PasteWebKit (or just use easy_install!) Mailing list, etc: http://pythonpaste.org/community/ Changes ------- This release brings bugfixes and new code. Thanks to Clark Evans for many of the contributions, and to Ben Bangert for giving this project more exercise. A quick overview: * A new exception-catching middleware (evalexception) for interactive debugging, including through-the-browser execution of Python code in the context of a traceback. * A paste.auth package for authentication/identification, including HTTP Basic/Digest, cookies, CAS (single-signon), and OpenID (another single-signon) * Many added improvements and conveniences for people working on the HTTP level, in the httpexceptions, httpheaders, fileapp modules. * Moving modules around to make the layout more logical (old imports are supported with warnings). * Paste Script has experimental new commands to install and setup web applications. Also improvements to the command-line interaction. * Paste Deploy and WebKit are largely maintenance releases. What Is It? ----------- Paste is a set of tools for building web applications and frameworks using WSGI. All the pieces are framework-neutral, and facilitate both high-level (non-leaky) abstractions built on top of them (frameworks) and low-level access to raw WSGI/HTTP. Paste Deploy is a way to configure WSGI applications and application stacks using Egg plugin facilities and a simple configuration file. It offers uniformity to web application deployment and configuration. Paste Script is a pluggable frontend for managing projects, and for serving up web applications using Paste Deploy and pluggable WSGI servers. Paste WebKit is an implementation of Webware/WebKit using WSGI and the tools in Paste. -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org

PyCon: Plone, Python, BitTorrent keynotes
by A.M. Kuchling Jan. 8, 2006

Jan. 8, 2006

The keynotes at PyCon 2006 can now be announced. Alan Runyan and Alexander Limi will open the conference with a keynote about Plone. I haven't received a title yet, but I expect it will provide an overview of Plone's current status, how it's developed, and where the Plone project is headed. On the middle day of the conference (Saturday), Guido van Rossum will give his traditional State of Python talk that will presumably cover the new features that were introduced in Python 2.4 and the features coming in Python 2.5. On the final day, we'll have Bram Cohen, creator of BitTorrent. The format won't be a conventional keynote; instead, Cohen has requested to be interviewed. An interviewer hasn't been chosen yet, but you can suggest questions on a wiki page at <http://wiki.python.org/moin/PyCon2006/BramCohenInterview>. A.M. Kuchling amk(a)amk.ca Chair, PyCon 2006 http://us.pycon.org
