ANN: distlib 0.3.2 released on PyPI
by Vinay Sajip 31 May '21

31 May '21

I've recently released version 0.3.2 of distlib on PyPI [1]. For newcomers, distlib is a library of packaging functionality which is intended to be usable as the basis for third-party packaging tools. The main changes in this release are as follows: * Fixed #139: improved handling of errors related to the test PyPI server. * Fixed #140: allowed "Obsoletes" in more scenarios, to better handle faulty metadata already on PyPI. * Fixed #141: removed unused regular expression. * Fixed #143: removed normcase() to avoid some problems on Windows. * Fixed #146: added entry for SourcelessFileLoader to the finder registry. * Fixed #147: permission bits are now preserved on POSIX when installing from a wheel. * Made the generation of scripts more configurable. * Added support for manylinux wheel tags. A more detailed change log is available at [2]. Please try it out, and if you find any problems or have any suggestions for improvements, please give some feedback using the issue tracker!

mimedecode 3.1.0
by Oleg Broytman 23 May '21

23 May '21

mimedecode WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is good because it allows us to use appropriate format/encoding/whatever. Sometimes, though, some unification is desirable. For example, one may want to put mail messages into an archive, make HTML indices, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary attachments is much desirable. Here is the solution - mimedecode. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which is treated as an RFC822 message, and decodes to stdout or an output file. If the file is not an RFC822 message it is just copied to the output one-to-one. If the file is a simple RFC822 message it is decoded as one part. If it is a MIME message with multiple parts ("attachments") all parts are decoded. Decoding can be controlled by command-line options. Think about said mail archive; for example, its maintainer wants to put there only texts, convert PDF/Postscript to text, pass HTML and images decoding base64 to html but leaving images encoded, and ignore everything else. This is how it could be done: mimedecode -t application/pdf -t application/postscript -t text/plain -b text/html -B 'image/*' -i '*/*' Version 3.1.0 (2021-05-23) Convert mimedecode.docbook to reST. Generate html/man/text using Sphinx. Replaced outdated and insecure `mktemp` with `NamedTemporaryFile`. Python 3.8, 3.9.

plum-py 0.6.0 release (Pack / Unpack Memory bytes)
by Dan Gass 21 May '21

21 May '21

I am pleased to announce the availability of beta release 0.6.0 of the "plum-py" package. This pure Python package provides classes and utility functions to transform byte sequences into Python objects and back. While similar in purpose to Python's standard library ``struct`` module, this package provides a larger set of format specifiers and is extensible, allowing you to easily create complex ones of your own. Docs: https://plum-py.readthedocs.io/en/latest/index.html PyPi: https://pypi.org/project/plum-py/ Repo: https://gitlab.com/dangass/plum Install: pip install plum-py License: MIT With Regards, Dan Gass (dan.gass at gmail) Change List ========= - Add support to ArrayX for packing/unpacking an array with a dims header. - Add SizedX transform for packing/unpacking an object with a size header. - Fix anomalous NameError exception which occurred when unpacking a structure member which has a default and set to "readonly" (occurred for cases where the eval of the string representation of default value is not the same object as the default value itself).

EuroPython 2021: Talk Voting is Open
by Marc-Andre Lemburg 17 May '21

17 May '21

Talk voting is your chance to tell us what you’d like to see at EuroPython 2021. We will leave talk voting open until: Sunday, May 23, 23:59:59 CEST In order to vote, please log in to the website and navigate to the talk voting page: * EuroPython 2021 Talk Voting * https://ep2021.europython.eu/events/talk-voting/ Who can participate? -------------------- Any registered attendee of EuroPython 2021 with a paid ticket, as well as attendees of one of the past EuroPython conferences (going back to 2015) can vote. If you have submitted a proposal this year, you are also eligible to vote. If you have not attended EuroPython before, but want to participate in talk voting, you have to buy a ticket before you can vote: https://ep2021.europython.eu/registration/buy-tickets/ How talk voting works --------------------- The talk voting interface lists all submitted proposals, including talks, helpdesks and posters. You can then vote on the proposal you'd like to see at the event. Details on the voting process are described on our talk voting page. Talk Selection -------------- After the talk voting phase, the EuroPython Program Workgroup (WG) will use the votes to select the talks and build a schedule. The talk voting is a good and strong indicator of what attendees are interested to see. Submissions are also selected based on editorial criteria, for example, to increase diversity, give a chance to less mainstream topics and make sure that topics don't overlap too much. In general, the Program WG will try to give as many speakers a chance to talk as possible. If speakers have submitted multiple talks, the one with the highest rating will most likely get selected. Quick Summary ------------- EuroPython 2021 will be run online from July 26 - August 1: - Two workshop/training days (July 26 - 27) - Three conference days (July 28 - 30) - Two sprint days (July 31 - August 1) The sessions will be scheduled to ensure they are also accessible for those in the Asian and Americas time zones.

plum-py 0.5.0 released
by Dan Gass 11 May '21

11 May '21

I am pleased to announce the availability of beta release 0.5.0 of the "plum-py" package. While this release contains many breaking changes, the API should now remain relatively stable until the anticipated 1.0.0 release expected later this year. This pure Python package provides classes and utility functions to transform byte sequences into Python objects and back. While similar in purpose to Python's standard library ``struct`` module, this package provides a larger set of format specifiers and is extensible, allowing you to easily create complex ones of your own. Docs: https://plum-py.readthedocs.io/en/latest/index.html PyPi: https://pypi.org/project/plum-py/ Repo: https://gitlab.com/dangass/plum License: MIT With Regards, Dan Gass (dan.gass at gmail) Change List ========= - This beta release contains many breaking changes! This release note entry attempts to summarize most breaking changes. Please read the extensively rewritten documentation to assess in detail what has changed. - Python 3.6 support dropped. - Changed most plum constructs (e.g. `Int`, `Float`, etc.) from being a data store type (with transform properties) into a simple transform type (e.g. `IntX`, `FloatX`, etc.). Instead of subclassing to obtain a custom transform, now instantiate the transform. - `ByteArray` data store eliminated and replaced with `BytesX` transform. - Added `ItemsX` transform for specifying dict, list, tuple formats. - Structure & BitFields changes - Bitfield members `cls` argument name changed to `typ`. - Member `cls` argument name changed to `fmt`. - Type annotations no longer used for the member format transform (previously if `cls` was unspecified, the annotation was used). - Pack operations no longer accept dictionaries. - Reduced number of member definition classes (same abilities exist, but features were added to standard `Member` to accomodate them). - `pack()` now only usable as a class method. `ipack()` introduced for usage on instances. - Pack operations now return `bytes` instead of `bytearray`. - Unpack operations no longer support File I/O as input buffer. - `pack()` and `unpack()` functions/methods offer more flexibility for specifying data transform format. - `pack_into()` eliminated. - `unpack_from()` eliminated (use `Buffer` construct instead).
