ANN: Lea 1.2 (discrete probability distributions)
by pie.denis＠skynet.be Dec. 13, 2013

Dec. 13, 2013

I have the pleasure to announce the release of Lea 1.2. Lea is a Python package aiming at working with discrete probability distributions in an intuitive way. It allows modelling a broad range of random discrete phenomenons. Then, it allows calculating probabilities of events, whether atomic, aggregated or combined through given operations. A typical example is the probabilities of the sum of N dice having known, possibly unfair, probability distributions. Features -------- Here are the main features of Lea: - models finite discrete probability distributions - standard distribution indicators (mean, standard deviation,.) - arithmetic and logical operators on probability distribution - cartesian products, conditional probabilities, joint distributions - generation of random samples - open-source project, LGPL license - pure Python module, lightweight - no package dependency - probabilities stored as integers (no floating-point biases) Links ----- Download (PyPi): http://pypi.python.org/pypi/lea Project page: http://code.google.com/p/lea/ (with wiki documentation including tutorials, examples and API) Hoping this could be helpful in this uncertain universe...

wigiki - build static html sites using github gists as pages
by Tasos Latsas Dec. 12, 2013

Dec. 12, 2013

Hello everyone, Posting here in case someone else finds this interesting. Wigiki is still work in progress (version 0.6) but is currently usable. I use Github's Gists a lot, mostly for note-taking and I wanted a painless way to group some of these notes into a wiki-like site. So, the main idea is that you write a json file with a list of gist ids and some other info and then run wigiki to build a static html site. The gists are not currently downloaded but they are embedded [1] thus the generated site is not suitable for offline reading. It ships with a very basic and minimal theme but I have also started working on a bootstrap-based one. A theme is basically a bunch of jinja2 templates following some conventions so that other people can hack/contribute themes. Wigiki source code [2] and documentation [3] are hosted on github. You can download from there or from pypi [4]. Cheers [1]: https://github.com/blog/122-embedded-gists [2]: https://github.com/tlatsas/wigiki [3]: http://tlatsas.github.io/wigiki/ [4]: https://pypi.python.org/pypi/wigiki -- Tasos Latsas GPG Key : 0x414301DF

PyDev 3.1.0 released
by Fabio Zadrozny Dec. 12, 2013

Dec. 12, 2013

Hi All, PyDev 3.1.0 has been released Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com LiClipse (PyDev standalone with goodies such as support for Django Templates, Mako Templates, Html, Javascript, etc): http://brainwy.github.io/liclipse/ Release Highlights: ------------------------------- * **Important**: PyDev requires Eclipse 3.8 or 4.3 onwards and Java 7! For older versions, keep using PyDev 2.x. * **Refactoring**: * It's now possible to rename a module (using F2 or drag and drop in the pydev package explorer). * Multiple improvements on the rename refactoring. * **Debugger**: * **Automatic code reloading on the debugger** (based on xreload). * When a file is changed and a debug session is on, PyDev will automatically reload it (based on xreload). * View https://github.com/fabioz/Pydev/blob/development/plugins/org.python.pydev/p… caveats/limitations. * **Get referrers on debug** * Right-click expression or variable in debugger and select 'Get Referrers' * Note: may not work on some Python variants as it needs access to the gc module. * **Stackless python** is now supported in the debugger, showing all the suspended tasklets in the stack view. * Automatically force focus to Eclipse on breakpoint hit (Enable in prefereces > pydev > debug). * The remote debugger can be left 'always on' (Enable in prefereces > pydev > debug). * If there's an exception while evaluating a conditional breakpoint the thread is suspended and the issue reported. * Option to skip caught exceptions thrown and handled in the same context. * A comment with @IgnoreException can be added to lines where an exception is thrown to have that exception ignored by the debugger when caught exceptions support is turned on. * Improved visualization of frame objects. * Bug-fixes on Jython debugging. * **Unittest**: * Django: The default PyDev unittest runner can now run Django tests properly * Selecting a unit-test method in the editor and **right-click > run as unit-test** will run only the selected unit-test. * **Ctrl+F9** with test selected will pre-select only that test to run in unit-test. * **General**: * Improvements on search for references (Ctrl+Shift+G). * Fixed some racing conditions related to the plugin startup. * Organize imports has option to add from imports before other imports. * Improved connection to shell that does code-completion. * Properly supporting creation of shell inside a Jython VM in Eclipse. What is PyDev? --------------------------- PyDev is a plugin that enables users to use Eclipse for Python, Jython and IronPython development -- making Eclipse a first class Python IDE -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, refactor, debug and many others. Cheers, -- Fabio Zadrozny ------------------------------------------------------ Software Developer LiClipse http://brainwy.github.io/liclipse PyDev - Python Development Environment for Eclipse http://pydev.org http://pydev.blogspot.com

pytest-2.5.0: many fixes. ZERO reported bugs left.
by holger krekel Dec. 12, 2013

Dec. 12, 2013

pytest-2.5.0: many fixes ... now down to ZERO reported bugs! =========================================================================== pytest-2.5.0 is a big bug fixing release, the result of two community bug fixing days plus numerous additional works from many people and reporters. The release should be fully compatible to 2.4.2, existing plugins and test suites. We aim at maintaining this level of ZERO reported bugs because it's no fun if your testing tool has bugs, is it? Under a condition, though: when submitting a bug report please provide clear information about the circumstances and a simple example which reproduces the problem. The issue tracker is of course not empty now. We have many remaining "enhancement" issues which we'll hopefully can tackle in 2014 with your help. For those who use older Python versions, please note that pytest is itself not automatically tested anymore on python2.5 due to virtualenv, setuptools and tox not supporting it anymore. Manual verification shows that it works fine still but that might change in the future. As usual, current docs are at http://pytest.org and you can upgrade from pypi via:: pip install -U pytest Particular thanks for helping with this release go to Anatoly Bubenkoff, Floris Bruynooghe, Marc Abramowitz, Ralph Schmitt, Ronny Pfannschmidt, Donald Stufft, James Lan, Rob Dennis, Jason R. Coombs, Mathieu Agopian, Virgil Dupras, Bruno Oliveira, Alex Gaynor and others. have fun, holger krekel 2.5.0 ----------------------------------- - dropped python2.5 from automated release testing of pytest itself which means it's probably going to break soon (but still works with this release we believe). - simplified and fixed implementation for calling finalizers when parametrized fixtures or function arguments are involved. finalization is now performed lazily at setup time instead of in the "teardown phase". While this might sound odd at first, it helps to ensure that we are correctly handling setup/teardown even in complex code. User-level code should not be affected unless it's implementing the pytest_runtest_teardown hook and expecting certain fixture instances are torn down within (very unlikely and would have been unreliable anyway). - PR90: add --color=yes|no|auto option to force terminal coloring mode ("auto" is default). Thanks Marc Abramowitz. - fix issue319 - correctly show unicode in assertion errors. Many thanks to Floris Bruynooghe for the complete PR. Also means we depend on py>=1.4.19 now. - fix issue396 - correctly sort and finalize class-scoped parametrized tests independently from number of methods on the class. - refix issue323 in a better way -- parametrization should now never cause Runtime Recursion errors because the underlying algorithm for re-ordering tests per-scope/per-fixture is not recursive anymore (it was tail-call recursive before which could lead to problems for more than >966 non-function scoped parameters). - fix issue290 - there is preliminary support now for parametrizing with repeated same values (sometimes useful to to test if calling a second time works as with the first time). - close issue240 - document precisely how pytest module importing works, discuss the two common test directory layouts, and how it interacts with PEP420-namespace packages. - fix issue246 fix finalizer order to be LIFO on independent fixtures depending on a parametrized higher-than-function scoped fixture. (was quite some effort so please bear with the complexity of this sentence :) Thanks Ralph Schmitt for the precise failure example. - fix issue244 by implementing special index for parameters to only use indices for paramentrized test ids - fix issue287 by running all finalizers but saving the exception from the first failing finalizer and re-raising it so teardown will still have failed. We reraise the first failing exception because it might be the cause for other finalizers to fail. - fix ordering when mock.patch or other standard decorator-wrappings are used with test methods. This fixues issue346 and should help with random "xdist" collection failures. Thanks to Ronny Pfannschmidt and Donald Stufft for helping to isolate it. - fix issue357 - special case "-k" expressions to allow for filtering with simple strings that are not valid python expressions. Examples: "-k 1.3" matches all tests parametrized with 1.3. "-k None" filters all tests that have "None" in their name and conversely "-k 'not None'". Previously these examples would raise syntax errors. - fix issue384 by removing the trial support code since the unittest compat enhancements allow trial to handle it on its own - don't hide an ImportError when importing a plugin produces one. fixes issue375. - fix issue275 - allow usefixtures and autouse fixtures for running doctest text files. - fix issue380 by making --resultlog only rely on longrepr instead of the "reprcrash" attribute which only exists sometimes. - address issue122: allow @pytest.fixture(params=iterator) by exploding into a list early on. - fix pexpect-3.0 compatibility for pytest's own tests. (fixes issue386) - allow nested parametrize-value markers, thanks James Lan for the PR. - fix unicode handling with new monkeypatch.setattr(import_path, value) API. Thanks Rob Dennis. Fixes issue371. - fix unicode handling with junitxml, fixes issue368. - In assertion rewriting mode on Python 2, fix the detection of coding cookies. See issue #330. - make "--runxfail" turn imperative pytest.xfail calls into no ops (it already did neutralize pytest.mark.xfail markers) - refine pytest / pkg_resources interactions: The AssertionRewritingHook PEP302 compliant loader now registers itself with setuptools/pkg_resources properly so that the pkg_resources.resource_stream method works properly. Fixes issue366. Thanks for the investigations and full PR to Jason R. Coombs. - pytestconfig fixture is now session-scoped as it is the same object during the whole test run. Fixes issue370. - avoid one surprising case of marker malfunction/confusion:: @pytest.mark.some(lambda arg: ...) def test_function(): would not work correctly because pytest assumes @pytest.mark.some gets a function to be decorated already. We now at least detect if this arg is an lambda and thus the example will work. Thanks Alex Gaynor for bringing it up. - xfail a test on pypy that checks wrong encoding/ascii (pypy does not error out). fixes issue385. - internally make varnames() deal with classes's __init__, although it's not needed by pytest itself atm. Also fix caching. Fixes issue376. - fix issue221 - handle importing of namespace-package with no __init__.py properly. - refactor internal FixtureRequest handling to avoid monkeypatching. One of the positive user-facing effects is that the "request" object can now be used in closures. - fixed version comparison in pytest.importskip(modname, minverstring) - fix issue377 by clarifying in the nose-compat docs that pytest does not duplicate the unittest-API into the "plain" namespace. - fix verbose reporting for @mock'd test functions
