PyDev 5.5.0 Released
by Fabio Zadrozny Jan. 31, 2017

Jan. 31, 2017

PyDev 5.5.0 Release Highlights ------------------------------- * **Important** PyDev now requires Java 8 and Eclipse 4.6 (Neon) onwards. * PyDev 5.2.0 is the last release supporting Eclipse 4.5 (Mars). * If you enjoy PyDev, you can help in keeping it supported through its Patreon crowdfunding: https://www.patreon.com/fabioz. * **Refactoring** * Fixed refactoring error when dealing with imports which have a continuation char inside the module name part. **#PyDev-712** * When extracting a method, decorators are properly considered for the new method position. **#PyDev-321** * **Code completion** * When accessing enums, 'value' and 'name' are properly found. **#PyDev-591** * Code completion improved on method chaining. **#PyDev-636** and **#PyDev-583** * It's now possible to choose whether when a code-completion which adds a local import should add the import to the beginning of the function or the line above where it was requested. * It may be configured in the preferences (Preferences > PyDev > Editor > Code Completion > Put local imports on top of method?). * Default was changed to add it to the top of the method. * **New actions** * **Ctrl+Shift+Alt+O** can be used to open the last hyperlink in the console that's currently open (it's now possible to jump directly to the error in some exception). **#PyDev-755** * **Ctrl+2,sw** switches the target and value in assign statements (may not work properly if more than one '=' is found in the line). * **Debugger** * Fixed error when hovering over variable when debugging. **#PyDev-580** * **Others** * Fixed issue in grammar parsing on nested async calls. **#PyDev-753** * Fixed issue grouping imports when an import has a continuation char inside the module part. **#PyDev 712** What is PyDev? --------------------------- PyDev is an open-source Python IDE on top of Eclipse for Python, Jython and IronPython development. It comes with goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, interactive console, etc. Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com What is LiClipse? --------------------------- LiClipse is a PyDev standalone with goodies such as support for Multiple cursors, theming, TextMate bundles and a number of other languages such as Django Templates, Jinja2, Kivy Language, Mako Templates, Html, Javascript, etc. It's also a commercial counterpart which helps supporting the development of PyDev.

ANN: A new version (0.4.0) of python-gnupg has been released.
by Vinay Sajip Jan. 29, 2017

Jan. 29, 2017

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is an enhancement and bug-fix release, and all users are encouraged to upgrade. See the project website [1] for more information. Brief summary: * Added support for ``KEY_CONSIDERED`` in more places - encryption / decryption, signing, key generation and key import. * Partial fix for #32 (GPG 2.1 compatibility). Unfortunately, better support cannot be provided at this point, unless there are certain changes (relating to pinentry popups) in how GPG 2.1 works. * Fixed #60: An IndexError was being thrown by ``scan_keys()``. * Ensured that utf-8 encoding is used when the ``--with-column`` mode is used. Thanks to Yann Leboulanger for the patch. * ``list_keys()`` now uses ``--fixed-list-mode``. Thanks to Werner Koch for the pointer. This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vina... at yahoo.co.uk> Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 What Does It Do? ================ The gnupg module allows Python programs to make use of the functionality provided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as it makes use of the subprocess module which appeared in that version of Python. This module is a newer version derived from earlier work by Andrew Kuchling, Richard Jones and Steve Traugott. A test suite using unittest is included with the source distribution. Simple usage: >>> import gnupg >>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') >>> gpg.list_keys() [{ ... 'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2', 'keyid': '197D5DAC68F1AAB2', 'length': '1024', 'type': 'pub', 'uids': ['', 'Gary Gross (A test user) <gary.gr... at gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.da... at delta.com>']}] >>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A']) >>> str(encrypted) '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n \nhQIOA/6NHMDTXUwcEAf . -----END PGP MESSAGE-----\n' >>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret') >>> str(decrypted) 'Hello, world!' >>> signed = gpg.sign("Goodbye, world!", passphrase='secret') >>> verified = gpg.verify(str(signed)) >>> print "Verified" if verified else "Not verified" 'Verified' As always, your feedback is most welcome (especially bug reports [3], patches and suggestions for improvement, or any other points via the mailing list/discussion group [4]). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

ANN: numexpr 2.6.2 released!
by Francesc Alted Jan. 29, 2017

Jan. 29, 2017

========================= Announcing Numexpr 2.6.2 ========================= What's new ========== This is a maintenance release that fixes several issues, with special emphasis in keeping compatibility with newer NumPy versions. Also, initial support for POWER processors is here. Thanks to Oleksandr Pavlyk, Alexander Shadchin, Breno Leitao, Fernando Seiti Furusato and Antonio Valentino for their nice contributions. In case you want to know more in detail what has changed in this version, see: https://github.com/pydata/numexpr/blob/master/RELEASE_NOTES.rst What's Numexpr ============== Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It wears multi-threaded capabilities, as well as support for Intel's MKL (Math Kernel Library), which allows an extremely fast evaluation of transcendental functions (sin, cos, tan, exp, log...) while squeezing the last drop of performance out of your multi-core processors. Look here for a some benchmarks of numexpr using MKL: https://github.com/pydata/numexpr/wiki/NumexprMKL Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that don't want to adopt other solutions requiring more heavy dependencies. Where I can find Numexpr? ========================= The project is hosted at GitHub in: https://github.com/pydata/numexpr You can get the packages from PyPI as well (but not for RC releases): http://pypi.python.org/pypi/numexpr Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy data! -- Francesc Alted
