"re-try" 0.7: Try Python regular expressions online
by Christof Hoeke 28 Mar '09

28 Mar '09

====== re-try ====== :version: 0.7 URL --- http://re-try.appspot.com/ what is it ---------- A small online browser application to try out Python regular expressions. It is based on http://cthedot.de/retest/ which has been around for some years but I never had a Python hosting service available so was only availabel for download. Putting it online on GAE was very easy though. The source code is not available publicly, if you are interested I might put it on Google Code or so. It is strongly based on retest 0.6.1 so no real surprises anyway. Please let me know what you think! thanks Christof

[ANN] pyxser-0.1r (release 0.1)
by Daniel Molina Wegener 26 Mar '09

26 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - From the readme file: - -----8<----------8<----------8<----------8<----- pxyser --- python xml serialization pyxser stands for Python XML Serialization, it's Python object serializer that does the job in a standard way. Unlike other serializers, it uses structured document defined in the pyxser DTD, has a FPI (forma public identifier) and the deserialization process run before validating the serialized object document against the pyxser DTD. it has the next functions: string pyxser.serialize(object) serilizes the given object and return it's XML representation. object pyxser.unserialize(string) deserializes the given string into it's native python reprsentation. it needs that all modules referenced in the serilized XML can be accesible to the pyxser extension. boolean pyxser.validate(string) validates the given XML string against the pyxser DTD. you don't need to call this function before every deserialization, because pyxser does the validation internally. A sample of a serialized object is the XML as follows: <?xml version="1.0" encoding="utf-8"?> <pyxs:obj xmlns:pyxs="http://projects.coder.cl/pyxser/model/" version="1.0" type="TestAnotherObject" module="testpkg.sample" id="id-136688140"> <pyxs:prop type="str" name="first_element">456</pyxs:prop> <pyxs:prop type="str" name="second_element">789</pyxs:prop> </pyxs:obj> pyxser supports cross referenced objects and nested referenced object, because it defines the a ref attribute as IDREF which is used to link internal nodes in the document tree. *** See the INSTALLING file for installing instructions. *** *** See the AUTHORS file to get information about the authors *** The pyxser web page is: http://coder.cl/software/pyxser/ Best regards, Daniel Molina Wegener ### $Id: README 29 2009-03-27 01:59:57Z damowe $ ### - -----8<----------8<----------8<----------8<----- Best regards, - -- .O. | Daniel Molina Wegener | FreeBSD & Linux ..O | dmw [at] coder [dot] cl | Open Standards OOO | http://coder.cl/ | FOSS Developer -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iQIcBAEBCgAGBQJJzEbaAAoJEHxqfq6Y4O5NXcEQAJQQqEWKvfbEKHZWC3RP4B/w isuiiyuVig7+nsBvRFoqoeTj5JtAUBN4xykH3TiqojYM7osA9+dPDRg7JfJtjf1t EaCB7u3HuIeR5udyoMpFSEpmJejr7gcMwOWLhBHZrhpgxhiAsioC1QjBtHsSnsuz 8pPp9/eqdTLvPhgkk8shFq0tvkM0pvF4/E9c4AACqz96frZO+S0jiIqPnu2VOkSq UX+/H2HkvvoDkh6+nS3vafC2VKC4U0c3MSu2rgljuxp5sDOBJLEYixCzw/U7Dtdo jgD12LPnqPa/3sQY2FsNkYosIp+Aj5C09i/jCc+MMw9RDJ3QmJaZtfC+0stU32xV w/WiOFjmGrgc+H3UmQXALdbTSbK/WyjX/iJ4R+04GCZW2y6b1IJwis//mPiWZe+K KgREo3KBx2wE/rrrHHEfmQZX/zaSxbY+qL4696OrB7q2lduyG6izmVBaOColJ/eY 5QDVrP0Y+NUL0j6rgd9gJj4/cG2sVr9aQant2WizwKSMK/fh3k/8gOLXU6JMjYTI e7mWWfjRrJGvgDGUD42EmAnuVXa4OAZUC20uH/kpCvfr+iAfM0WXk/6kzw1Qcu7o dHqXGK4/vHcVlX0UnJE843d5+eok932SkZPRLvM6L8pdwjB8nJ17P85pkfgysUDh Ofk5cKuQ2HF+EgH5Quki =QhlG -----END PGP SIGNATURE-----

Sphinx 0.6.1 and 0.5.2 released
by Georg Brandl 26 Mar '09

26 Mar '09

Hi all, I'm proud to announce the release of Sphinx 0.6.1 and 0.5.2. Sphinx 0.5.2 is a bugfix-only release in the 0.5 series, while 0.6.1 is a feature release, containing all of 0.5.2's fixes together with many added features. These are beta releases, so please test them out and report any bugs to sphinx-dev(a)googlegroups.com or the tracker at <http://bitbucket.org/birkenfeld/sphinx/>. Thank you! The finals will be out in a week's time, if no severe problems are uncovered. What is it? =========== Sphinx is a tool that makes it easy to create intelligent and beautiful documentation for Python projects (or other documents consisting of multiple reStructuredText source files). Website: http://sphinx.pocoo.org/ What's new in 0.6 (short version)? ================================== Long version: http://sphinx.pocoo.org/latest/changes.html * General/Markup: - Templating now requires the Jinja2 library, which is an enhanced version of the old Jinja1 engine. - Theming support, see the new section in the documentation. - Due to popular demand, added a ``:doc:`` role which directly links to another document without the need of creating a label to which a ``:ref:`` could link to. - Added a ``:download:`` role that marks a non-document file for inclusion into the HTML output and links to it. - Added an ``only`` directive that can selectively include text based on enabled "tags". Tags can be given on the command line. Also, the current builder output format (e.g. "html" or "latex") is always a defined tag. - Added HTML section numbers, enabled by giving a ``:numbered:`` flag to the ``toctree`` directive. - The ``literalinclude`` directive now supports several more options, to include only parts of a file. - The ``toctree`` directive now supports a ``:hidden:`` flag, which will prevent links from being generated in place of the directive -- this allows you to define your document structure, but place the links yourself. - Paths to images, literal include files and download files can now be absolute (like ``/images/foo.png``). They are treated as relative to the top source directory. - SVG images are now supported in HTML (via ``<object>`` and ``<embed>`` tags). * Configuration: - The new config value ``rst_epilog`` can contain reST that is appended to each source file that is read. This is the right place for global substitutions. - The new ``html_add_permalinks`` config value can be used to switch off the generated "paragraph sign" permalinks for each heading and definition environment. - The new ``html_show_sourcelink`` config value can be used to switch off the links to the reST sources in the sidebar. - The default value for ``htmlhelp_basename`` is now the project title, cleaned up as a filename. - The new ``modindex_common_prefix`` config value can be used to ignore certain package names for module index sorting. - The new ``trim_footnote_reference_space`` config value mirrors the docutils config value of the same name and removes the space before a footnote reference that is necessary for reST to recognize the reference. - The new ``latex_additional_files`` config value can be used to copy files (that Sphinx doesn't copy automatically, e.g. if they are referenced in custom LaTeX added in ``latex_elements``) to the build directory. * Builders: - The new ``DirectoryHTMLBuilder`` (short name ``dirhtml``) creates a separate directory for every page, and places the page there in a file called ``index.html``. Therefore, page URLs and links don't need to contain ``.html``. - The new ``html_link_suffix`` config value can be used to select the suffix of generated links between HTML files. - #96: The LaTeX builder now supports figures wrapped by text, when using the ``figwidth`` option and right/left alignment. * New translations: - Italian by Sandro Dentella. - Ukrainian by Petro Sasnyk. - Finnish by Jukka Inkeri. * Extensions and API: - New ``graphviz`` extension to embed graphviz graphs. - New ``inheritance_diagram`` extension to embed... inheritance diagrams! - New ``autosummary`` extension that generates summaries of modules and automatic documentation of modules. - Autodoc now has a reusable Python API, which can be used to create custom types of objects to auto-document (e.g. Zope interfaces). See also ``Sphinx.add_autodocumenter()``. - Autodoc now handles documented attributes. - Autodoc now handles inner classes and their methods. - Autodoc can document classes as functions now if explicitly marked with `autofunction`. - Autodoc can now exclude single members from documentation via the ``exclude-members`` option. - Autodoc can now order members either alphabetically (like previously) or by member type; configurable either with the config value ``autodoc_member_order`` or a ``member-order`` option per directive. * New command-line features: - Config overrides for single dict keys can now be given on the command line. - Source links in HTML are now generated with ``rel="nofollow"``. - Quickstart can now generate a Windows ``make.bat`` file. - There is now a ``-w`` option for sphinx-build that writes warnings to a file, in addition to stderr. - There is now a ``-W`` option for sphinx-build that turns warnings into errors. cheers, Georg

Announcing IronPython 2.6 Alpha 1
by Dave Fugate 26 Mar '09

26 Mar '09

Hello Python Community, We're pleased to announce the release of IronPython 2.6 Alpha 1. As you might imagine, this release is all about supporting new CPython 2.6 features such as the 'bytes' and 'bytearray' types (PEP 3112), decorators for classes (PEP 3129), advanced string formatting (PEP 3101), etc. The minimum .NET version required for this release is the same as IronPython 2.0; namely .NET 2.0 Service Pack 1. Unlike the 2.0 series of IronPython, we plan to release only a couple Alphas and Betas of IronPython 2.6. As such, it's key that we get your feedback on the release(s) quickly to incorporate requested changes. Besides CPython 2.6 features, another significant change in this release is that ipy.exe now uses "adaptive compilation" by default. Adaptive compilation is a technique in which IronPython: 1. Interprets and executes Python method calls up to N times for a given method. If you're only going to execute a method a few times, it's typically faster to interpret the method instead of compiling and executing it 2. Compiles and executes the Python method call on the N+1 invocation of the method. Compilation of a Python method is a heavyweight operation, but we can reuse the result for subsequent invocations 3. Reuses the previously compiled method for new calls to the Python method. This operation is much faster than interpreting the method call as the method was already compiled in the previous step The reason for this change is that it provides a nice performance gain for Python code containing lots of functions/methods that only get called a few times. All this said, this feature is still undergoing active development and as a consequence some Python scripts may actually run slower with it turned on. For this reason, our old default mode of running Python scripts is still available by passing the -O or -D flags to ipy.exe. Any feedback on how this new feature affects your IronPython applications performance-wise would be greatly appreciated. There's also a few minor changes since IronPython 2.0.1 that are worth calling out here: * IronPython.msi now installs NGEN'ed binaries by default * IronPython.msi now offers a little more selection with respect to what you'd like to install. For example, Silverlight templates are optional * The default installation location of IronPython.msi no longer indicates whether the 2.6 release is an Alpha, Beta, or a patched release. Future IronPython 2.6 installations will replace previous 2.6 releases which will be uninstalled automatically * The -X:PreferComInteropAssembly flag has been removed. All COM interop is now done through normal COM dispatch You can download IronPython 2.6 Alpha 1 at: http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=22982 The IronPython Team

"Advanced Scientific Programming in Python" Summer School in Berlin, Germany
by Tiziano Zito 25 Mar '09

25 Mar '09

"Advanced Scientific Programming in Python" a G-Node Summer School Many scientists spend much of their time writing, debugging, and maintaining software. But while techniques for doing this efficiently have been developed, only few scientists actually use them. As a result, they spend far too much time writing deficient code and reinventing the wheel instead of doing research. In this course we present a selection of advanced programming techniques with theoretical lectures and practical exercises tailored to the needs of the programming scientist. To spice up theory and foster our new skills in a real-world programming project, we will team up to develop an entertaining scientific computer game. We will use the Python programming language for the entire course. With a large collection of open-source scientific modules and all features of a full-fledged programming language, Python is rapidly gaining popularity in the neuroscience community. It enables the scientist to quickly develop powerful, efficient, and structured software and is becoming an essential tool for scientific computing. The summer school is targeted at Post-docs and PhD students from all areas of neuroscience. Substantial proficiency in Python or in another language (e.g. Java, C/C++, MATLAB, Mathematica) is absolutely required. An optional, one-day pre-course is offered to participants without Python experience to familiarize with the language. Date and Location ----------------- August 31st, 2009 -- September 4th, 2009. Berlin, Germany. Preliminary Program ------------------- Day 0 (Mon Aug 31) -- [Optional] Dive into Python Day 1 (Tue Sep 1) -- Software Carpentry - Documenting code and using version control - Test-driven development & unit testing - Debugging, profiling and benchmarking techniques - Object-oriented programming, design patterns and Extreme Programming Day 2 (Wed Sep 2) -- Scientific Tools for Python - NumPy, SciPy, Matplotlib, IPython - Neuroscience libraries - Programming project in the afternoon Day 3 (Thu Sep 3) -- Parallelization - Python multiprocessing for SMP machines - Distributed parallelization for cluster computing - Programming project in the afternoon Day 4 (Fri Sep 4) -- Practical Software Development - Software design - Efficient programming in teams - Quality Assurance - Finalizing the programming project Applications ------------ Applications should be sent before May 31st, 2009 to pythonsummerschool(a)bccnberlin.de. No fee is charged but participants should take care of travel, living, and accommodation expenses. Applications should include full contact information (name, affiliation, email & phone), a short CV and a short statement addressing the following questions (maximum 500 words): - What is your educational background? - What experience do you have in programming? - Why do you think "Advanced Scientific Programming in Python" is an appropriate course for your skill profile? Candidates will be selected based on their profile. Places are limited: early application is recommended.

bzr 1.13.1 released!
by Bob Tanner 23 Mar '09

23 Mar '09

A couple regessions where found in the 1.13 release. The pyrex- generated C extensions are missing from the .tar.gz and .zip files. Documentation on how to generate GNU ChangeLogs is wrong. The merge --force works again. The Bazaar team announces the availability of a regression release of the bzr adaptive version control system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from http://bazaar-vcs.org/ Download as a source tarball; packages for various systems will be available soon. BUG FIXES: * Change ``./bzr``'s ``_script_version`` to match ./bzrlib/ __init__.py version_info. (Bob Tanner, Martin Pool, #345232) * Distribution archives for 1.13 do not contain generated C extension modules (Jean-Francois Roy, Bob Tanner, #344465) * GNU ChangeLog output can now be produced by bzr log --format gnu-changelog is incorrect (Deejay, Bob Tanner, Martin Pool, Robert Collins, #343928) * ``merge --force`` works again.

ETS 3.2.0 Released
by Dave Peterson 23 Mar '09

23 Mar '09

Hello, I'm pleased to announce that Enthought Tool Suite (ETS) version 3.2.0 has been tagged and released! Source distributions (.tar.gz) have been uploaded to PyPi, and Windows binaries will be follow shortly. A full install of ETS can be done using Setuptools via a command like: easy_install -U "ets[nonets] >= 3.2.0" NOTE 1: Users of an old ETS release will need to first uninstall prior to installing the new ETS. NOTE 2: If you get a 'SandboxViolation' error, simply re-run the command again -- it may take multiple invocations to get everything installed. (This error appears to be a long-standing incompatibility between numpy.distutils and setuptools.) Please see below for a list of what's new in this release. What Is ETS? =========== The Enthought Tool Suite (ETS) is a collection of components developed by Enthought and the open-source community, which we use every day to construct custom scientific applications. It includes a wide variety of components, including: * an extensible application framework * application building blocks * 2-D and 3-D graphics libraries * scientific and math libraries * developer tools The cornerstone on which these tools rest is the Traits package, which provides explicit type declarations in Python; its features include initialization, validation, delegation, notification, and visualization of typed attributes. More information on ETS is available from the development home page: http://code.enthought.com/projects/index.php Changelog ========= ETS 3.2.0 is a feature-added update to ETS 3.1.0, including numerous bug-fixes. Some of the notable changes include: Chaco ----- * Domain limits - Mappers now can declare the "limits" of their valid domain. PanTool and ZoomTool respect these limits. (pwang) * Adding "hide_grids" parameter to Plot.img_plot() and Plot.contour_plot() so users can override the default behavior of hiding grids. (pwang) * Refactored examples to declare a Demo object so they can be be run with the demo.py example launcher. (vibha) * Adding chaco.overlays package with some canned SVG overlays. (bhendrix) * DragZoom now can scale both X and Y axes independently corresponding to the mouse cursor motion along the X and Y axes (similar to the zoom behavior in Matplotlib). (pwang) * New Examples: * world map (bhendrix) * more financial plots (pwang) * scatter_toggle (pwang) * stacked_axis (pwang) * Fixing the chaco.scales TimeFormatter to use the built-in localtime() instead of the one in the safetime.py module due to Daylight Savings Time issues with timedelta. (r23231, pwang) * Improved behavior of ScatterPlot when it doesn't get the type of metadata it expects in its "selections" and "selection_masks" metadata keys (r23121, pwang) * Setting the .range2d attribute on GridMapper now properly sets the two DataRange1D instances of its sub-mappers. (r23119, pwang) * ScatterPlot.map_index() now respects the index_only flag (r23060, pwang) * Fixed occasional traceback/bug in LinePlot that occurred when data was completely outside the visible range (r23059, pwang) * Implementing is_in() on legends to account for padding and alignment (caused by tools that move the legend) (r23052, bhendrix) * Legend behaves properly when there are no plots to display (r23012, judah) * Fixed LogScale in the chaco.scales package to correctly handle the case when the length of the interval is less than a decade (r22907, warren.weckesser) * Fixed traceback when calling copy_traits() on a DataView (r22894, vibha) * Scatter plots generated by Plot.plot() now properly use the "auto" coloring feature of Plot. (r22727, pwang) * Reduced the size of screenshots in the user manual. (r22720, rkern) Mayavi ------ * 17, 18 March, 2009 (PR): * NEW: A simple example to show how one can use TVTK’s visual module with mlab. [23250] * BUG: The size trait was being overridden and was different from the parent causing a bug with resizing the viewer. [23243] * 15 March, 2009 (GV): * ENH: Add a volume factory to mlab that knows how to set color, vmin and vmax for the volume module [23221]. * 14 March, 2009 (PR): * API/TEST: Added a new testing entry point: ‘mayavi -t’ now runs tests in separate process, for isolation. Added enthought.mayavi.api.test to allow for simple testing from the interpreter [23195]...[23200], [23213], [23214], [23223]. * BUG: The volume module was directly importing the wx_gradient_editor leading to an import error when no wxPython is available. This has been tested and fixed. Thanks to Christoph Bohme for reporting this issue. [23191] * 14 March, 2009 (GV): * BUG: [mlab]: fix positioning for titles [23194], and opacity for titles and text [23193]. * ENH: Add the mlab_source attribute on all objects created by mlab, when possible [23201], [23209]. * ENH: Add a message to help the first-time user, using the new banner feature of the IPython shell view [23208]. * 13 March, 2009 (PR): * NEW/API: Adding a powerful TCP/UDP server for scripting mayavi via the network. This is available in enthought.mayavi.tools.server and is fully documented. It uses twisted and currently only works with wxPython. It is completely insecure though since it allows a remote user to do practically anything from mayavi. * 13 March, 2009 (GV) * API: rename mlab.orientationaxes to mlab.orientation_axes [23184] * 11 March, 2009 (GV) * API: Expose ‘traverse’ in mlab.pipeline [23181] * 10 March, 2009 (PR) * BUG: Fixed a subtle bug that affected the ImagePlaneWidget. This happened because the scalar_type of the output data from the VTKDataSource was not being set correctly. Getting the range of any input scalars also seems to silence warnings from VTK. This should hopefully fix issues with the use of the IPW with multiple scalars. I’ve added two tests for this, one is an integration test since those errors really show up only when the display is used. The other is a traditional unittest. [23166] * 08 March, 2009 (GV) * ENH: Raises an error when the user passes to mlab an array with infinite values [23150] * 07 March, 2009 (PR) * BUG: A subtle bug with a really gross error in the GridPlane component, I was using the extents when I should really have been looking at the dimensions. The extract grid filter was also not flushing the data changes downstream leading to errors that are also fixed now. These errors would manifest when you use an ExtractGrid to select a VOI or a sample rate and then used a grid plane down stream causing very wierd and incorrect rendering of the grid plane (thanks to conflation of extents and dimensions). This bug was seen at NAL for a while and also reported by Fred with a nice CME. The CME was then converted to a nice unittest by Suyog and then improved. Thanks to them all. [23146] * 28 February, 2009 (PR) * BUG: Fixed some issues reported by Ondrej Certik regarding the use Of mlab.options.offscreen, mlab.options.backend = ‘test’, removed cruft from earlier ‘null’ backend, fixed bug with incorrect imports, add_dataset set no longer adds one new null engine each time figure=False is passed, added test case for the options.backend test. [23088] * 23 February, 2009 (PR) * ENH: Updating show so that it supports a stop keyword argument that pops up a little UI that lets the user stop the mainloop temporarily and continue using Python [23049] * 21 February, 2009 (GV) * ENH: Add a richer view for the pipeline to the MayaviScene [23035] * ENH: Add safegards to capture wrong triangle array sizes in mlab.triangular_mesh_source. [23037] * 21 February, 2009 (PR) * ENH: Making the transform data filter recordable. [23033] * NEW: A simple animator class to make it relatively to create animations. [23036] [23039] * 20 February, 2009 (PR) * ENH: Added readers for various image file formats, poly data readers and unstructured grid readers. These include DICOM, GESigna, DEM, MetaImage (mha,mhd) MINC, AVSucd, GAMBIT, Exodus, STL, Points, Particle, PLY, PDB, SLC, OBJ, Facet and BYU files. Also added several tests for most of this functionality along with small data files. These are additions from PR’s project staff, Suyog Jain and Sreekanth Ravindran. [23013] * ENH: We now change the default so the ImagePlaneWidget does not control the LUT. Also made the IPW recordable. [23011] * 18 February, 2009 (GV) * ENH: Add a preference manager view for editing preferences outside envisage [22998] * 08 February, 2009 (GV) * ENH: Center the glyphs created by barchart on the data points, as mentioned by Rauli Ruohonen [22906] * 29 January, 2009 (GV) * ENH: Make it possible to avoid redraws with mlab by using mlab.gcf().scene.disable_render = True [22869] * 28 January, 2009 (PR and GV) * ENH: Make the mlab.pipeline.user_defined factory function usable to add arbitrary filters on the pipeline. [22867], [22865] * 11 January, 2009 (GV) * ENH: Make mlab.imshow use the ImageActor. Enhance the ImageActor to map scalars to colors when needed. [22816] Traits ------ * Fixed a bug whereby faulty error handling in the PyProtocols Pyrex speedup code keeps references to tracebacks that have been handled. In so doing, clean up the same code such that it can be used with a modern Pyrex release (a bare raise can no longer be used outside of an except: clause). * RangeEditor factory now supports a 'logslider' mode: Thanks to Matthew Turk for the patch * TabularEditor factory now supports editing of all columns: Thanks to Didrik Pinte for the patch * DateEditor factory in 'custom' style now supports multi-select feature. * DateEditor and TimeEditor now support the 'readonly' style. * Fixed a bug in the ArrayEditor factory that was causing multiple trait change events to get fired when the underlying array is changed externally to the editor: Thanks to Matthew Turk for he patch. * Fixed a circular import error in Color, Font and RGBColor traits * Fixed a bug in the factory for ArrayViewEditor so it now calls the toolkit backend-specific editor TraitsBackendWX --------------- * RangeEditor now supports a 'logslider' mode: Thanks to Matthew Turk for the patch * TabularEditor now supports editing of all columns: Thanks to Didrik Pinte for the patch * DateEditor in 'custom' style now supports multi-select feature. * DateEditor and TimeEditor now support the 'readonly' style. * Added a trait to the wx pyface workbench View to indicate if the view dock window should be closeable. * Fixed the DirectoryEditor to popup the correct file dialog (thanks to Luca Fasano and Phil Thompson) * Fixed a circular import error in Color, Font and RGBColor traits * Fixed a bug in the ColorEditor that was causing the revert action to not work correctly. * Fixed a bug that caused a traceback when trying to undock a pyface dock window * Fixed a bug in the 'livemodal' view that caused the UI to become unresponsive if the 'updated' event was fired on the contained view. * Fixed bugs in ListEditor (notebook style) that caused a loss of sync between the 'selected' trait and the activated dock window.
