ANN: Expressions (alpha release) – Lightweight arithmetic expression parser for custom compilers
by Stefan Urbanek 31 Jul '13

31 Jul '13

Hi, Expressions is a lightweight arithmetic expression parser for creating simple arithmetic expression compilers. Sources: https://github.com/Stiivi/expressions Intended use: Embed custom expression evaluation into your application. For example: * variable checking compiler with allow/deny mechanism * unification of functions and variables if your app provides multiple backends which might provide expression evaluation functionality * compiler for custom object structures, such as for frameworks providing functional-programing like interface Note: still very alpha. Comments, questions, suggestions and fixes are appreciated. Stay light! Stefan Urbanek -- @Stiivi

PyPy3 2.1 beta 1 released
by Philip Jenvey 30 Jul '13

30 Jul '13

================ PyPy3 2.1 beta 1 ================ We're pleased to announce the first beta of the upcoming 2.1 release of PyPy3. This is the first release of PyPy which targets Python 3 (3.2.3) compatibility. We would like to thank all of the people who donated_ to the `py3k proposal`_ for supporting the work that went into this and future releases. You can download the PyPy3 2.1 beta 1 release here: http://pypy.org/download.html#pypy3-2-1-beta-1 Highlights ========== * The first release of PyPy3: support for Python 3, targetting CPython 3.2.3! - There are some `known issues`_ including performance regressions (issues `#1540`_ & `#1541`_) slated to be resolved before the final release. What is PyPy? ============== PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.3 or 3.2.3. It's fast due to its integrated tracing JIT compiler. This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. Also this release supports ARM machines running Linux 32bit - anything with ``ARMv6`` (like the Raspberry Pi) or ``ARMv7`` (like Beagleboard, Chromebook, Cubieboard, etc.) that supports ``VFPv3`` should work. Cheers, the PyPy team

Programming competition/course for high school students (NCSS Challenge)
by Georgina Wilcox 30 Jul '13

30 Jul '13

Hi The NCSS Challenge is an online programming competition for school students that teaches students to code in Python while they compete. No previous programming experience is required, although for experienced students we also have intermediate and advanced streams. The competition is appropriate for students aged 11 to 18 (although this is not a strict rule, it depends on the student, contact us for more info). The competition runs for 5 weeks, starting next Monday 5th August. Registration costs $20 (Australian) per student per stream. Registration gives students access to notes, questions, forums where they can interact with other competitors, and a messaging system where they can ask for help from our team of volunteer tutors. The competition is run by the University of Sydney, Australia. Questions last year were on a range of topics from bioinformatics to natural language processing, number theory and cryptography. It's a great opportunity to get kids engaged with programming and computational thinking. For more information, see our website http://groklearning.com/challenge, or email challenge(a)ncss.edu.au Regards, Georgina Wilcox Tutor | National Computer Science School PhD Candidate | University of Sydney <P><A HREF=" https://groklearning.com/challenge?utm_source=clpya&utm_medium=email&utm_ca…">NCSS Challenge</A> - an online programming competition for high school students. (30-July-13)

Download ======== The new release is available from ftp.gnome.org: http://download.gnome.org/sources/pygobject/3.9/pygobject-3.9.5.tar.xz (652K) sha256sum: e785e24b001517dd57fc5cc2b7ddeb56b459555307561675edb47c11c80a85d5 What’s new since PyGObject 3.9.3 ================================ - Ensure exceptions set in closure out argument marshaling are printed (Simon Feltman) (#705064) - Always raise OverflowError for marshaling integers from Python (not ValueError or OverflowError) (Simon Feltman) (#705057) - Cleanup invoke args and kwargs combiner code (Simon Feltman) (#640812) - gtk-demo: Change demo to use Gtk.Application (Simon Feltman) (#698547) - Add callable and descriptor protocols to PyGICallableInfo (Simon Feltman) (#704037) - Unify basic type argument marshaling for methods, closures, and properties (Simon Feltman) (#693405) - Override GValue.set/get_boxed with static C marshaler (Simon Feltman) (#688081, #693405) - Add deprecation warning for marshaling arbitrary objects as pointers (Simon Feltman) (#688081) - Replace usage of __import__ with importlib.import_module (Simon Feltman) (#682320) - Always unref the GiTypeInfo when generating an argument cache (Mike Gorse) (#703973) - Unref interface info when fetching enums or flags (Mike Gorse) (#703960) - Speed up MRO calculation (Daniel Drake) (#703829) - Add GIL safety to pyobject_copy for copying boxed PyObjects (Simon Feltman) (#688081) - Add marshaling of GI_TYPE_TAG_VOID held in a GValue to int (Simon Feltman) (#694233) - GTK overrides: Make connect_signals handle tuple (Cole Robinson) (#693994) - Re-add support for passing GValue's by reference (Simon Feltman) (#701058) - Clear return value of closures to zero when an exception occurs (Simon Feltman) (#702552) - Don't use doctest syntax in docstrings for examples (Martin Pitt) (#701009) - Add support for properties of type GInterface (Garrett Regier) (#703456) - pygtkcompat: Fix for missing methods on Windows (Martin Pitt) (#702787) - gi/pygi-info.c: Avoid C99-style variable declaration (Chun-wei Fan) (#702786) About PyGObject =============== GObject is a object system used by GTK+, GStreamer and other libraries. PyGObject provides a convenient wrapper for use in Python programs when accessing GObject libraries. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject now dynamically accesses any GObject libraries that uses GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to gobject library it is instantly available as a Python API without the need for intermediate Python glue. Simon

[ANN] pyspread 0.2.4
by Martin Manns 23 Jul '13

23 Jul '13

============== pyspread 0.2.4 ============== Pyspread 0.2.4 is released. Besides Linux, the new version also runs on Windows (Windows 7 64bit and Windows XP 32bit tested). About pyspread ============== Pyspread is a non-traditional spreadsheet application that is based on and written in the programming language Python. The goal of pyspread is to be the most pythonic spreadsheet application. Pyspread is free software. It is released under the GPL v3. Project website: http://manns.github.com/pyspread/ What is new in 0.2.4 ==================== + Windows compatibility + More charts and chart options (box plots, histograms, pie charts) + Export of matplotlib charts to svg, png, pdf, eps and ps + Import from UTF-8 encoded csv files (no other encoding, yet) + More than 64k characters supported in one cell + Insertion and deletion of rows and columns now affect only the current table + High quality in-cell bitmaps images (with transparency) supported + Iterable data can be pasted into multiple cells via Paste As... + Pyspread can now be started from other Python applications + Partly localized in Nowegian Nynorsk and Bokmaal Known issues ============ + Selection mode is disabled in Windows. + "Find & Replace All" is slow in grids with much data unless pyspread is minimized. + Paste As... does not work if dates are present in the data structure. + Sometimes, pressing redo when there is nothing left to redo has undesired effects such as redoing an operation again. + When updating from a non-release version (from git), the file ~/.pyspreadrc (in Windows pyspread's registry entry) may have to be deleted. Enjoy Martin

by engelbert gruber 22 Jul '13

22 Jul '13

hello , I finally got around to release, PLEASE report anything failings to me. summary of changes since 0.10 * General - Apply [ 2714873 ] Fix for the overwritting of document attributes. - Support embedded aliases within hyperlink references. - Fix [ 228 ] try local import of docutils components (reader, writer, parser, language module) before global search. * docutils/parsers/rst/directives/tables.py - Fix [ 210 ] Python 3.3 checks CVS syntax only if "strict" is True. * docutils/writers/html4css1/__init__.py - Fix [ 3600051 ] for tables in a list, table cells are not compacted. - New setting `stylesheet_dirs` (see above). Now, it is easy to add a custom stylesheet to Docutils' default stylesheet with, e.g., ``--stylesheet_path='html4css1.css, mystyle.css'`` Changed behaviour of the default settings: if there is a file ``html4css1.css`` in the working directory of the process at launch, it is used instead of the one provided by Docutils in the writer source directory. - New default for math-output_: ``HTML math.css``. - Avoid repeated class declarations in html4css1 writer (modified version of patch [ 104 ]). .. _math-output: docs/user/config.html#math-output * docutils/writers/latex2e/__init__.py - Drop the simple algorithm replacing straight double quotes with English typographic ones. Activate the SmartQuotes_ transform if you want this feature. - New setting `stylesheet_dirs`: Comma-separated list of directories where stylesheets are found. Used by `stylesheet_path` when expanding relative path arguments. .. _SmartQuotes: docs/user/config.html#smart-quotes * docutils/writers/manpage.py - Fix [3607063] handle lines starting with a period. - Fix option separating comma was bold (thanks to Bill Morris). all the best engelbert
