ANN: lfm v3.0
by Iñigo Serna Oct. 23, 2015

Oct. 23, 2015

Hi all, after many years, new version of lfm; now compatible with Python 3.4+. Description =========== Last File Manager is a powerful file manager for the UNIX console. It has a curses interface and it's written in Python v3.4+. Licensed under GNU Public License version 3 or later. Some of the features you can find in lfm: - console-based file manager for UNIX platforms - 1-pane or 2-pane view - tabs - files filters - bookmarks - history - VFS for compressed files - tree view - dialogs with entry completion - PowerCLI, a command line interface with advanced features - fast access to the shell - direct integration of find/grep, df and other tools - color files by extension [Andrey Skvortsov] - fully customizable themes (colors) - fully customizable key bindings - support for filenames with wide chars, f.e. East Asian - ...and many others Home page: https://inigo.katxi.org/devel/lfm/ Pypi: https://pypi.python.org/pypi/lfm Code repository: https://bitbucket.org/inigoserna/lfm3 Changes since last version ========================== Version 3.0 ("Only you") - 2015/10/23: + About the code - almost completely rewritten from scratch . it hasn't been tested as much as lfm v2.x series on non-linux OS - requires Python v3.4+ - pyview, the file viewer, has been removed from lfm package - configuration location has changed to a new directory and files: ~/.config/lfm/{lfm.ini, lfm.keys, lfm.theme, lfm.history} + New features - fully customizable themes (colors) - fully customizable key bindings . allow Alt-key shorcuts (A-) . only for main window (not for dialogs) - files filters (using globs) . information in pane frame: ".F" => show dotfiles, active filters . filters are a property of a tab, they remain active even when chdir . Ctrl-f: edit current filter . Some examples: . "*.png,*.jpg" => hide all PNG and JPEG files . "*.jpg,!*shot*" => hide all JPEG files except those with 'shot' in the name . "*,!*py" => hide all except python source files - up to 35 bookmarks (0-9, a-z) . b: go to bookmark, B: set bookmark, C-d: select bookmark . fix: don't delete bookmark at start if path does not exist - nested archive handling (vfs inside vfs) works now - added optional support for filenames with wide chars, f.e. East Asian . to enable, set 'use_wide_chars' flag in configuration or use -w command line flag . it's disabled by default for performance . it's not perfect, but it mostly works - there are 2 different versions of move_file to chose from in the key bindings file: . move_file: old implementation . move_file2: alternative version using shtutil.move instead of copy & delete. Faster but less control of errors - new action: redraw screen (default key A-r) + Changes & improvements (vs v2.x): - chmod & chown/chgrp are 2 different actions now - cursor_goto_file (C-s): find text pattern (no regex or glob) in the whole file name, not at the beginning as v2.x - cursor_goto_file_1char (A-s): go to file by 1st letter of name (old C-s behaviour) - bookmarks have new key bindings: b: go to bookmark, B: set bookmark, C-d: select bookmark - PowerCLI: . ending command with % must be $ now . added new date variables: dm, dc, da, dn . ending command with % must be $ now . added new date variables: dm, dc, da, dn . old $d variable is $p now - find/grep: panelize = create vfs with matched files . if rebuild: all files modifications or deletions are translated to original directory so be careful! - pyview, the file viewer, has been removed from lfm package + Fixes in v3.0 (vs v2.x): - nested archive handling (vfs inside vfs) works now - find & grep with spaces in file name - wide chars file names support (f.e. Eastern languages) => lfm -w - sort by size after show dirs size - move_file: not overwritten files in destination are not deleted Of course, all comments, suggestions, etc. are welcome. Best regards, Iñigo Serna

ANN: SortedContainers 1.4.2 released
by Grant Jenks Oct. 21, 2015

Oct. 21, 2015

Announcing the release of SortedContainers version 1.4.2 What is SortedContainers? ------------------------- SortedContainers is an Apache2-licensed, pure-Python implementation of sorted list, sorted dict, and sorted set data types that is fast-as-C implementations with 100% code coverage and hours of stress testing. The project is fully documented with performance benchmarks and comparisons to alternative implementations. What's new in 1.4.2? -------------------- * Updated docs to warn against editing sorted containers during iteration. Don't do it. * Updated SortedList* comparisons to match Sequence comparison as described in CPython Language Reference Section 5.9. https://docs.python.org/2/reference/expressions.html This also lead to the discovery of a bug in the blist.sortedlist implementation (filed as Issue #77 in their bug tracker). https://github.com/DanielStutzbach/blist/issues/77 * Updated SortedSet comparison to raise NotImplemented on type mismatch. * Bug Fix: Fixed reference to self._dict in sorteddict.ValuesView.count. * Bug Fix: SortedSet.__ior__ now calls `update` rather than `union`. * Improved performance of SortedList.__getitem__ by 35% for head and tail indexing. * Improved performance of SortedList.pop by 35% by inlining fast-paths of internal indexing methods. * Improved performance of `del sorted_list[:]` by simply calling `clear`. * Improved performance of `sorted_list[:] = values` by simply calling `clear` then `update`. * Updated SortedListWithKey to inherit directly from SortedList. Removed redundant methods. Merged sortedlistwithkey.py into sortedlist.py. * Updated SortedList to accept a key-argument callable that will dynamically return a SortedListWithKey instance. * Added new __init__ benchmark comparison. SortedContainers is generally 5-10x faster than other implementations. * Added reference to ruamel.ordereddict.sorteddict on performance comparison page at http://www.grantjenks.com/docs/sortedcontainers/performance.html * Removed SortedList._slice in favor of slice.indices. * Removed SortedList.as_list in favor of `list(sorted_list)`. * Updated benchmarks using CPython 2.7.10 and CPython 3.4.3. See docs for complete version strings. * Added CPython 3.5 runtime to test frameworks configs. * Added docs reference to Debian distributions at python-sortedcontainers and python3-sortedcontainers. Links ----- - Documentation: http://www.grantjenks.com/docs/sortedcontainers/ - Download: https://pypi.python.org/pypi/sortedcontainers - Source: https://github.com/grantjenks/sorted_containers - Issues: https://github.com/grantjenks/sorted_containers/issues This release is mostly backwards-compatible. Please upgrade.

aiosmtpd 1.0a1 - asyncio-based implementations of SMTP/LMTP
by Barry Warsaw Oct. 20, 2015

Oct. 20, 2015

I'm very happy to announce the first alpha release of aiosmtpd, an asyncio-based implementation of SMTP and LMTP. http://aiosmtpd.readthedocs.org/en/latest/ https://pypi.python.org/pypi/aiosmtpd/1.0a1 This library can be used as a standalone server, or as a testing framework for applications that send email. It's inspired by several previous packages including the stdlib smtpd.py, lazr.smtptest, Benjamin Bader's aiosmtp, and submodules in GNU Mailman. This is an alpha release, so it can obviously use lots of feedback, and contributions are very much welcome. We're developing the library on GitLab; see the RTD link above for details. Brought to you by the aiosmtpd hacking cabal of Andrew Kuchling, Eric Smith, Jason Coombs, R. David Murray and myself. Our aim is to include aiosmtpd in the Python 3.6 stdlib as a better alternative to smtpd.py. Cheers, -Barry

rJSmin 1.0.12
by André Malo Oct. 18, 2015

Oct. 18, 2015

Hello World, I'm pleased to announce version 1.0.12 of rJSmin. About rJSmin ============ rJSmin is a javascript minifier written in python. The minifier is based on the semantics of jsmin.c by Douglas Crockford. The module is a re-implementation aiming for speed, so it can be used at runtime (rather than during a preprocessing step). Usually it produces the same results as the original jsmin.c. It differs in the following ways: - there is no error detection: unterminated string, regex and comment literals are treated as regular javascript code and minified as such. - Control characters inside string and regex literals are left untouched; they are not converted to spaces (nor to \n) - Newline characters are not allowed inside string and regex literals, except for line continuations in string literals (ECMA-5). - "return /regex/" is recognized correctly. - Line terminators after regex literals are handled more sensibly - "+ +" and "- -" sequences are not collapsed to "++" or "--" - Newlines before ! operators are removed more sensibly - Comments starting with an exclamation mark ('!') can be kept optionally - rJSmin does not handle streams, but only complete strings. (However, the module provides a "streamy" interface). About Release 1.0.12 ==================== - Reworked handling of comments starting with exclamation marks. The matcher should no longer get out of sync, even if they appear in the middle of other matches - Handle line terminators before and after regex literals more sensible Supported Python Versions ========================= * Python 2.4 - 2.7 * Python 3.2 - * PyPy 1.9 - * Jython 2.5 - (Python only) License ======= rJSmin is available under the terms and conditions of the "Apache License, Version 2.0." Links ===== * Homepage + Documentation: http://opensource.perlig.de/rjsmin/ * PyPI: https://pypi.python.org/pypi/rjsmin * Github: https://github.com/ndparker/rjsmin * License: http://www.apache.org/licenses/LICENSE-2.0 André "nd" Malo

Pythran 0.7.2 is out!
by serge guelton Oct. 13, 2015

Oct. 13, 2015

(sorry for the double posting, if any) Dear pythraners and pythonistae (the latin plural for pythonista?) It is my pleasure to announce the release of Pythran 0.7.2, now available on - pypy: https://pypi.python.org/pypi/pythran - conda: https://anaconda.org/serge-sans-paille/pythran - github: https://github.com/serge-sans-paille/pythran Pythran is an ahead-of-time Python compiler with a focus on high-level scientific computing. It relies on a few non-intrusive annotations to provide (potentially) vectorized, parallel version of high level Python code, like the following, borrowed from stackoverflow [0]; #pythran export GrayScott(int, float, float, float, float) # ^ see the non intrusive, backward compatible annotation ^ import numpy as np def GrayScott(counts, Du, Dv, F, k): n = 300 U = np.zeros((n+2,n+2), dtype=np.float32) V = np.zeros((n+2,n+2), dtype=np.float32) u, v = U[1:-1,1:-1], V[1:-1,1:-1] r = 20 u[:] = 1.0 U[n/2-r:n/2+r,n/2-r:n/2+r] = 0.50 V[n/2-r:n/2+r,n/2-r:n/2+r] = 0.25 u += 0.15*np.random.random((n,n)) v += 0.15*np.random.random((n,n)) for i in range(counts): Lu = ( U[0:-2,1:-1] + U[1:-1,0:-2] - 4*U[1:-1,1:-1] + U[1:-1,2:] + U[2: ,1:-1] ) Lv = ( V[0:-2,1:-1] + V[1:-1,0:-2] - 4*V[1:-1,1:-1] + V[1:-1,2:] + V[2: ,1:-1] ) uvv = u*v*v u += Du*Lu - uvv + F*(1 - u) v += Dv*Lv + uvv - (F + k)*v return V This minor yet amazing version brings in more numpy function support [1], easier install, a conda build, tentative windows support, faster compilation time and generates generally faster native modules. Kudos to Pierrick for the hardwork and to all the bug reporters. You all help a lot to bring the motivation high. Special thanks to the OpenDreamKit[2] project for the financial support. Most of the new features have been implemented thanks to this funding! Changelog extract: 2015-10-13 Serge Guelton <serge.guelton(a)telecom-bretagne.eu> * Significantly decrease compilation time * Faster execution of numpy generalized slicing * Tentative conda support * Tentative Windows support (using Win Python) * Preserve original docstrings * Add __pythran__ global variable to pythran generated modules * Faster implementation of various itertools functions * Rely on distutils for module code compilation * Support most of numpy.random * Remove git and make dependency to install nt2 * Proper pip support instead of distuils * Remove dependency to boost.python * Remove dependency to tcmalloc * Pythonic library cleaning (less dependencies / header / splitting / mrpropering) * More lazy computations * More numpy function support (including dot on matrices, linalg.norm, mean) * Lot of code cleaning / refactoring (both in Python and C++) * Many bugfixes, thanks to all the bug reporters!

rCSSmin 1.0.6
by André Malo Oct. 11, 2015

Oct. 11, 2015

Hello World, I'm pleased to announce version 1.0.6 of rCSSmin. About rCSSmin ============= rCSSmin is a CSS minifier written in python based on the semantics of the YUI compressor, which itself is based on the rule list by Isaac Schlueter. This module is a re-implementation aiming for speed instead of maximum compression, so it can be used at runtime (rather than during a preprocessing step). RCSSmin does syntactical compression only (removing spaces, comments and possibly semicolons). It does not provide semantic compression (like removing empty blocks, collapsing redundant properties etc). It does, however, support various CSS hacks (by keeping them working as intended): - IE7 hack (``>/**/``) - Mac-IE5 hack (``/*\*/.../**/``) - The boxmodelhack is supported naturally because it relies on valid CSS2 strings - Between ``:first-line`` and the following comma or curly brace a space is inserted. (apparently it's needed for IE6) - Same for ``:first-letter`` Comments starting with an exclamation mark (``!``) can be kept optionally. About Release 1.0.6 =================== This release mainly fixes the minification of calc() calls (Issue #1). Additionally it lifts installation restrictions for future python versions. Supported Python Versions ========================= * Python 2.4 - 2.7 * Python 3.2 - * PyPy 1.9 - * Jython 2.5 - (Python only) License ======= rCSSmin is available under the terms and conditions of the "Apache License, Version 2.0." Links ===== * Homepage + Documentation: http://opensource.perlig.de/rcssmin/ * PyPI: https://pypi.python.org/pypi/rcssmin * Github: https://github.com/ndparker/rcssmin * License: http://www.apache.org/licenses/LICENSE-2.0 André "nd" Malo

rJSmin 1.0.11
by André Malo Oct. 11, 2015

Oct. 11, 2015

Hello World, I'm pleased to announce version 1.0.11 of rJSmin. About rJSmin ============ rJSmin is a javascript minifier written in python. The minifier is based on the semantics of jsmin.c by Douglas Crockford. The module is a re-implementation aiming for speed, so it can be used at runtime (rather than during a preprocessing step). Usually it produces the same results as the original jsmin.c. It differs in the following ways: - there is no error detection: unterminated string, regex and comment literals are treated as regular javascript code and minified as such. - Control characters inside string and regex literals are left untouched; they are not converted to spaces (nor to \n) - Newline characters are not allowed inside string and regex literals, except for line continuations in string literals (ECMA-5). - "return /regex/" is recognized correctly. - "+ +" and "- -" sequences are not collapsed to "++" or "--" - Newlines before ! operators are removed more sensibly - Comments starting with an exclamation mark ('!') can be kept optionally - rJSmin does not handle streams, but only complete strings. (However, the module provides a "streamy" interface). About Release 1.0.11 ==================== This release lifts installation restrictions for future python versions. Supported Python Versions ========================= * Python 2.4 - 2.7 * Python 3.2 - * PyPy 1.9 - * Jython 2.5 - (Python only) License ======= rJSmin is available under the terms and conditions of the "Apache License, Version 2.0." Links ===== * Homepage + Documentation: http://opensource.perlig.de/rjsmin/ * PyPI: https://pypi.python.org/pypi/rjsmin * Github: https://github.com/ndparker/rjsmin * License: http://www.apache.org/licenses/LICENSE-2.0 André "nd" Malo

ANN: Eliot 0.9, the logging system with causality - now with journald support
by Itamar Turner-Trauring Oct. 8, 2015

Oct. 8, 2015

Eliot 0.9 is out, with a new utility for pretty-printing log messages and native journald support [1]. You can now route Eliot logs to journald and when an error occurs easily find all logged actions that led up to that particular error, as opposed to most logging systems where this would involve reading all the logs and figuring out which ones apply and which to ignore. Most logging systems can tell you what happened; Eliot tells you _why_ it happened: $ python linkcheck.py | eliot-tree 4c42a789-76f5-4f0b-b154-3dd0e3041445 +-- check_links@1/started `-- urls: [u'http://google.com', u'http://nosuchurl'] +-- download@2,1/started `-- url: http://google.com +-- download@2,2/succeeded +-- download@3,1/started `-- url: http://nosuchurl +-- download@3,2/failed |-- exception: requests.exceptions.ConnectionError |-- reason: ('Conn aborted', gaierror(-2, 'Name unknown')) +-- check_links@4/failed |-- exception: exceptions.ValueError |-- reason: ('Conn aborted.', gaierror(-2, 'Name unknown')) And here's the code that generated these logs (eliot-tree [2] was used to render the output): import sys from eliot import start_action, to_file import requests to_file(sys.stdout) def check_links(urls): with start_action(action_type="check_links", urls=urls): for url in urls: try: with start_action(action_type="download", url=url): response = requests.get(url) response.raise_for_status() except Exception as e: raise ValueError(str(e)) check_links(["http://google.com"], ["http://nosuchurl"]) Interested?

First release of pytest-vw!
by Florian Bruhin Oct. 7, 2015

Oct. 7, 2015

Hey, I'm happy to announce the first release of pytest-vw, a pytest plugin which makes failing test cases succeed in continuous integration tools. See https://github.com/The-Compiler/pytest-vw for more information. Of course, any similarities with a current event concerning (but not limited to) a multinational automobile manufacturer are purely coincidental. (In all seriousness: This was mainly to try the excellent cookiecutter[1] and cookiecutter-pytest-plugin[2] projects - it's also inspired by (read: a blatant ripoff of) PHPunit VW) [1] https://github.com/audreyr/cookiecutter [2] https://github.com/pytest-dev/cookiecutter-pytest-plugin [3] https://github.com/hmlb/phpunit-vw Florian -- http://www.the-compiler.org | me(a)the-compiler.org (Mail/XMPP) GPG: 916E B0C8 FD55 A072 | http://the-compiler.org/pubkey.asc I love long mails! | http://email.is-not-s.ms/

pytest 2.8.2 released
by Florian Bruhin Oct. 7, 2015

Oct. 7, 2015

Hey, I'm happy to announce pytest 2.8.2 has been released. In case you wonder, pytest is a widely used mature test runner both for unit and functional test purposes in python. See http://pytest.org for documentation and examples. Among other things, this release fixes a regression introduced in 2.8.1 when using parametrize with encoded byte strings: - fix #1085: proper handling of encoding errors when passing encoded byte strings to pytest.parametrize in Python 2. Thanks Themanwithoutaplan for the report and Bruno Oliveira for the PR. - fix #1087: handling SystemError when passing empty byte strings to pytest.parametrize in Python 3. Thanks Paul Kehrer for the report and Bruno Oliveira for the PR. - fix #995: fixed internal error when filtering tracebacks where one entry was generated by an exec() statement. Thanks Daniel Hahler, Ashley C Straw, Philippe Gauthier and Pavel Savchenko for contributing and Bruno Oliveira for the PR. Thanks to all who contributed to this release, among them: Bruno Oliveira Demian Brecht Florian Bruhin Ionel Cristian Mărieș Raphael Pierzina Ronny Pfannschmidt holger krekel There are still some regressions open from 2.8, among them an issue when using objects with a custom __getattr__ with Python 2.6: https://github.com/pytest-dev/pytest/issues/1035 Fixes for those issues are in progress, and there hopefully will be a 2.8.3 release soon. Thanks for flying pytest and sorry for the turbulences! ;) Florian -- http://www.the-compiler.org | me(a)the-compiler.org (Mail/XMPP) GPG: 916E B0C8 FD55 A072 | http://the-compiler.org/pubkey.asc I love long mails! | http://email.is-not-s.ms/
