tox-1.1: bug fixes and improved workflow
by holger krekel 09 Jul '11

09 Jul '11

Hey all, i just released tox-1.1, the virtualenv/test/CI automation tool. See here for general information and install info: http://codespeak.net/~hpk/tox or http://tox.readthedocs.org (which is missing some navigation links at time of sending email) The release incorporates a number of bug fixes and an enhanced work flow: repeatedly calling tox without increasing version numbers now works (by calling pip -U --nodeps). With this release i consider tox pretty stable and fit for general use. best & thanks to all contributors, holger krekel 1.1 ----------------- - fix issue5 - don't require argparse for python versions that have it - fix issue6 - recreate virtualenv if installing dependencies failed - fix issue3 - fix example on frontpage - fix issue2 - warn if a test command does not come from the test environment - fixed/enhanced: except for initial install always call "-U --no-deps" for installing the sdist package to ensure that a package gets upgraded even if its version number did not change. (reported on TIP mailing list and IRC) - inline virtualenv.py (1.6.1) script to avoid a number of issues, particularly failing to install python3 environents from a python2 virtualenv installation. - rework and enhance docs for display on readthedocs.org

pytest-2.1.0: perfected assertions/bug fixes
by holger krekel 09 Jul '11

09 Jul '11

Welcome to the relase of pytest-2.1, a mature testing tool for Python, supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See the improved extensive docs (now also as PDF!) with tested examples here: http://pytest.org/ The single biggest news about this release are **perfected assertions** courtesy of Benjamin Peterson. You can now safely use ``assert`` statements in test modules without having to worry about side effects or python optimization ("-OO") options. This is achieved by rewriting assert statements in test modules upon import, using a PEP302 hook. See http://pytest.org/assert.html#advanced-assertion-introspection for detailed information. The work has been partly sponsored by my company, merlinux GmbH. For further details on bug fixes and smaller enhancements see below. If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest best, holger krekel / http://merlinux.eu Changes between 2.0.3 and 2.1.0 ---------------------------------------------- - fix issue53 call nosestyle setup functions with correct ordering - fix issue58 and issue59: new assertion code fixes - merge Benjamin's assertionrewrite branch: now assertions for test modules on python 2.6 and above are done by rewriting the AST and saving the pyc file before the test module is imported. see doc/assert.txt for more info. - fix issue43: improve doctests with better traceback reporting on unexpected exceptions - fix issue47: timing output in junitxml for test cases is now correct - fix issue48: typo in MarkInfo repr leading to exception - fix issue49: avoid confusing error when initizaliation partially fails - fix issue44: env/username expansion for junitxml file path - show releaselevel information in test runs for pypy - reworked doc pages for better navigation and PDF generation - report KeyboardInterrupt even if interrupted during session startup - fix issue 35 - provide PDF doc version and download link from index page

ANN: EPD 7.1 released
by Ilan Schnell 07 Jul '11

07 Jul '11

Hello, I am pleased to announce that EPD (Enthought Python Distribution) version 7.1 has been released. The most significant change is the addition of an "EPD Free" version, which has its own very liberal license, and can be downloaded and used free of any charge by anyone (not only academics). "EPD Free" includes a subset of the packages included in the full EPD. The highlights of this subset are: numpy, scipy, matplotlib, traits and chaco. To see which libraries are included in the free vs. full version, please see: http://www.enthought.com/products/epdlibraries.php In addition we have opened our PyPI build mirror for everyone. This means that one can type "enpkg xyz" for 10,000+ packages. However, there are still benefits to becoming an EPD subscriber. http://www.enthought.com/products/getepd.php Apart from the addition of "EPD Free", this release includes updates to over 30 packages, including numpy, scipy, ipython and ETS. We have also added PySide, Qt and MDP to this release. Please find the complete list of additions, updates and bug fixes in the change log: http://www.enthought.com/products/changelog.php About EPD --------- The Enthought Python Distribution (EPD) is a "kitchen-sink-included" distribution of the Python programming language, including over 90 additional tools and libraries. The EPD bundle includes NumPy, SciPy, IPython, 2D and 3D visualization, and many other tools. EPD is currently available as a single-click installer for Windows XP, Vista and 7, MacOSX (10.5 and 10.6), RedHat 3, 4 and 5, as well as Solaris 10 (x86 and x86_64/amd64 on all platforms). All versions of EPD (32 and 64-bit) are free for academic use. An annual subscription including installation support is available for individual and commercial use. Additional support options, including customization, bug fixes and training classes are also available: http://www.enthought.com/products/epd_sublevels.php - Ilan

FLiP-1.2 : Logical Framework in Python
by Jon Jacky 07 Jul '11

07 Jul '11

FLiP-1.2, a logical framework in Python, has been released. Code, documentation, and downloads are available: http://staff.washington.edu/jon/flip/www/ http://pypi.python.org/pypi/FLiP/ https://github.com/jon-jacky/FLiP Version 1.2 is organized into packages and provides a distutils install. These may make FLiP easier to use and extend. It also includes a case study based on the "She's a witch!" scene from Monty Python and the Holy Grail. The functionality is the same as in version 1.0, as it was announced here in July 2009: -------- FLiP is a logical framework written in Python. A logical framework is a library for defining logics and writing applications such as theorem provers. One Flip application is a proof checker for entering and editing proofs in natural deduction style. Here is some output from the checker, generated from a Python proof script: [(Text('~Ax.P(x) |- Ex.~P(x)'), comment), (Not(A(x, P(x))), given), (Not(E(x, Not(P(x)))), assume), (New(x), new), (Not(P(x)), assume), (E(x, Not(P(x))), Ei, 4), (F, contra, 5,2), (Not(Not(P(x))), raa, 4,6), (P(x), ne, 7), (A(x, P(x)), Ai, 3,8), (F, contra, 9,1), (Not(Not(E(x, Not(P(x))))), raa, 2,10), (E(x, Not(P(x))), ne, 11)] The checker can use different logics; Flip comes with several. You can add another logic, or add axioms and derived rules, by writing a module in Python. Python is both the object language and the metalanguage. Formulas, inference rules, and entire proofs are Python expressions. Prover commands are Python functions. The Python interpreter itself is the only user interface to the proof checker application. (It is not necessary to know much Python to use the checker.) Flip was undertaken as a Python programming exercise. It is not intended to compete with industrial-strength theorem provers such as HOL nor with nicely-designed educational provers such as Jape. That said, the checker is quite capable of working the examples and exercises in university-level textbooks on logic for computer science or mathematics (such as those by Kaye, Huth and Ryan, or Bornat).

DEAP 0.7 : Distributed Evolutionary Algorithms in Python
by Félix-Antoine Fortin 07 Jul '11

07 Jul '11

Hi everyone, We are proud to annouce the release of DEAP 0.7, a library for doing Distributed Evolutionary Algorithms in Python. You can download a copy of this release at the following web page. http://deap.googlecode.com For those who wouldn't already know about the project, it is built around two major parts, EAP and DTM. EAP has been built using the Python and UNIX programming philosophies in order to provide a transparent, simple and coherent environment for implementing your favourite evolutionary algorithms. EAP is very easy to use even for those who do not know much about the Python programming language. EAP uses both the object oriented and functional programming paradigm that are provided by Python in order to make development simple and beautiful. It also contains more than 20 illustrative and diversified examples, to help newcomers to ramp up very quickly in using this environment. The D part of DEAP, called DTM, is under intense development and currently available as an alpha version (0.2). DTM provides tools to distribute workload evenly on a cluster or LAN of workstations, based on MPI and TCP communication managers. The load balancing is based on a new epidemiologic model. This unique model allows unique possibilities, like tasks spawning other tasks that can be run on any available workers. This release includes a lot of new examples, a cleaner API, new features like easy statistics computation and a benchmark module, new variation methods for finer control on algorithms, and a few bug fixes. Your feedback and comments are welcome at <deap-users at googlegroups dot com>. You can also follow us on Twitter @deapdev, and on our blog http://deapdev.wordpress.com/ Best, François-Michel De Rainville Félix-Antoine Fortin Marc-André Gardner Christian Gagné Marc Parizeau Laboratoire de vision et systèmes numériques Département de génie électrique et génie informatique Université Laval Quebec City (Quebec), Canada
