ANN: PDFBuilder can now handle unlimited input files

by vasudevram

(Cross-posted to comp.lang.python) PDFBuilder, which is a part of my xtopdf toolkit, can now handle an unlimited (*1) number of input files. PDFBuilder enables the creation of composite PDFs consisting of the content of multiple CSV and TDV/TSV files (*2). Support for other formats can be added easily. (*2) TDV = Tab Delimited Values, TSV = Tab Separated Values Blog post about the latest version of PDFBuilder: PDFBuilder can now handle unlimited input files: http://jugad2.blogspot.in/2013/07/pdfbuilder-can-now-handle-unlimited.html (*1) See the above post for the meaning of "unlimited". PDFBuilder is available here as part of the xtopdf toolkit: https://bitbucket.org/vasudevram/xtopdf xtopdf (and hence PDFBuilder) is released as open source software under the BSD License.

[ANN] pyparsing 2.0.1 released - compatible with Python 2.6 and later

by Paul McGuire

In my releasing of Pyparsing 1.5.7/2.0.0 last November, I started to split supported Python versions: 2.x to the Pyparsing 1.5.x track, and 3.x to the Pyparsing 2.x track. Unfortunately, this caused a fair bit of pain for many current users of Python 2.6 and 2.7 (especially those using libs dependent on pyparsing), as the default installed pyparsing version using easy_install or pip would be the incompatible-to-them pyparsing 2.0.0. I hope I have rectified (or at least improved) this situation with the latest release of pyparsing 2.0.1. Version 2.0.1 takes advantage of the cross-major-version compatibility that was planned into Python, wherein many of the new features of Python 3.x were made available in Python 2.6 and 2.7. By avoiding the one usage of ‘nonlocal’ (a Python 3.x feature not available in any Python 2.x release), I’ve been able to release pyparsing 2.0.1 in a form that will work for all those using Python 2.6 and later. (If you are stuck on version 2.5 or earlier of Python, then you still have to explicitly download the 1.5.7 version of pyparsing.) This release also includes a bugfix to the new ‘<<=’ operator, so that ‘<<’ for attachment of parser definitions to Forward instances can be deprecated in favor of ‘<<=’. Hopefully, most current users using pip and easy_install can now just install pyparsing 2.0.1, and it will be sufficiently version-aware to function under all Pythons 2.6 and later. Thanks for your continued support and interest in pyparsing! -- Paul McGuire

ANN: rom 0.16 - Redis object mapper for Python

by Josiah Carlson

Hey everyone, As time progresses, so does my Redis object mapper. The "rom" package is a Redis object mapper for Python. It sports an interface similar to Django's ORM, SQLAlchemy + Elixir, or Appengine's datastore. The changelog for recent releases can be seen below my signature. You can find the package at: https://www.github.com/josiahcarlson/rom https://pypi.python.org/pypi/rom Please CC me on any replies if you have any questions or comments. Thank you, - Josiah #----------------------------------- 0.16 ------------------------------------ [added] Thanks to a feature request from https://github.com/jrsmith , Boolean column support is now available. [added] DateTime, Date, and Time column types because I was already adding Boolean columns. #----------------------------------- 0.15 ------------------------------------ [fixed] Thanks to https://github.com/MickeyKim who fixed Json columns so that they round-trip after multiple saves. #----------------------------------- 0.14 ------------------------------------ [fixed] Thanks to https://github.com/mayfield the manifest is fixed for the source installation. #----------------------------------- 0.13 ------------------------------------ [fixed] updating a model will no longer unindex the model on attributes that weren't updated. Thanks to https://github.com/mayfield for the bug report, analysis, and initial pull request that ultimately resulted in the fix. [fixed] pip requires, versioning, etc., thanks to fixes from https://github.com/mayfield [changed] Model.get_by() will now work on any type of indexed columns. Unique columns work as before, and other columns get pass-through to the Model.query interface. [changed] Model.get_by() and Model.query.filter() will both accept single numbers as the value to match on (you don't need to specify a range if you are querying by equality). [changed] all changes will be documented in this changelog.txt file to keep a list of everything that is going on with the project.

[ANN] bbfreeze 1.1.2

by Ralf Schmitt

Hi, I've just released bbfreeze 1.1.2. The code is available from pypi https://pypi.python.org/pypi/bbfreeze/ or from github https://github.com/schmir/bbfreeze bbfreeze creates stand-alone executables from python scripts. It's similar in purpose to the well known py2exe for windows, py2app for OS X, PyInstaller and cx_Freeze (in fact ancient versions were based on cx_Freeze. And it uses the modulegraph package, which is also used by py2app). It has the following features: easy installation bbfreeze can be installed with setuptools' easy_install command. zip/egg file import tracking bbfreeze tracks imports from zip files and includes whole egg files if some module is used from an eggfile. Packages using setuputils' pkg_resources module will now work (new in 0.95.0) binary dependency tracking bbfreeze will track binary dependencies and will include DLLs and shared libraries needed by a frozen program. multiple script freezing bbfreeze can freeze multiple scripts at once. python interpreter included bbfreeze will create an extra executable named 'py', which might be used like the python executable itself. automatic pathname rewriting pathnames in tracebacks are replaced with relative pathnames (i.e. if you import package foo.bar from /home/jdoe/pylib/ tracebacks generated from functions in foo.bar will not show your local path /home/jdoe/pylib/foo/bar.py. They will instead show foo/bar.py) distutils command 'bdist_bbfreeze' A new distutils/setuptools command bdist_bbfreeze integrates bbfreeze into your setup.py. bbfreeze works on windows and UNIX-like operating systems. bbfreeze has been tested with python 2.4, 2.5, 2.6 and 2.7 bbfreeze will not work with python 3 or higher. -- Cheers Ralf

ANN: eGenix EuroPython 2013 Talks & Videos

by eGenix Team: M.-A. Lemburg

________________________________________________________________________ ANNOUNCING eGenix EuroPython 2013 Talks & Videos This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/EuroPython-2013-Presentations.html ________________________________________________________________________ We have just published the talks slides and videos of our EuroPython 2013 presentations. The EuroPython Conference is the one of the premier conferences for Python users and developers. This year it was held from July 1-7 in Florence, Italy. ________________________________________________________________________ EGENIX TALKS AT EUROPYTHON At this year's EuroPython, Marc-André Lemburg, CEO of eGenix, gave the following two talks at the conference, providing some insights into our experience with running Python projects. The presentations are available for viewing and download from our Presentations and Talks section. http://www.egenix.com/library/presentations/ Designing Large-Scale Applications in Python -------------------------------------------- Concepts for designing large and scalable Python applications that work in practice. Python is often referred to as a scripting language. While Python is an ideal platform for scripting, integration or plugin tasks, it does in fact cover all the concepts needed for truly large-scale object oriented application development. However, complex applications bring new challenges. The talk will draw on the speaker’s experience with large-scale application design using Python as central implementation language and provide a cookbook approach to many of the problems you face when designing and organizing complex application frameworks. The approach has been proven in many real-life projects, ranging from web application servers in varying fields of application to complete finance trading systems. Python has always proven to be a truly good choice with an outstanding time-to-market advantage over other implementation languages such as Java or C++. It allows small software development companies to successfully compete against multi-million dollar ventures. Talk video and slides: http://www.egenix.com/library/presentations/EuroPython2013-Designing-Large-… and Efficient Python development with small teams --------------------------------------------- As we all know, Python is a very efficient implementation language - so efficient, that you sometimes face new challenges in projects. Very often, you can completely skip the prototype phase and go directly to the main development phase. Customers love this, of course, but this approach tends to come with its own unique set of requirements and problems. Team size, communication, application design, work distribution, milestone and customer expectation management are important factors for the success of such a project. The talk will discuss a few strategies that have worked in many larger projects and also touch upon some things that did not work out well.

[ANN]:JSONStream

by Sol Toure

I was trying to process a large file containing a number of distinct JSON object as a stream, but I couldn't find anything readily available to that. (maybe I didn't search hard enough) So I came up with this: https://github.com/qrtz/JSONStream I hope you find it useful too.

PyPy 2.1 beta 1 released

by David Schneider

=============== PyPy 2.1 beta 1 =============== We're pleased to announce the first beta of the upcoming 2.1 release of PyPy. This beta contains many bugfixes and improvements, numerous improvements to the numpy in PyPy effort. The main feature being that the ARM processor support is not longer considered alpha level. We would like to thank the Raspberry PiFoundation (http://www.raspberrypi.org) for supporting the work to finish PyPy's ARM support. You can download the PyPy 2.1 beta 1 release here: http://pypy.org/download.html Highlights ========== * Bugfixes to the ARM JIT backend, so that ARM is now an officially supported processor architecture * Stacklet support on ARM * Interpreter improvements * Various numpy improvements * Bugfixes to cffi and ctypes * Bugfixes to the stacklet support * Improved logging performance * Faster sets for objects What is PyPy? ============= PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.3. It's fast due to its integrated tracing JIT compiler. This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. Also this release supports ARM machines running Linux 32bit - anything with ``ARMv6`` (like the Raspberry Pi) or ``ARMv7`` that supports ``VFPv3`` should work. Cheers, the PyPy team

ANN: psutil 1.0.0 released

by Giampaolo Rodola'

Hi there folks, I'm pleased to announce the 1.0.0 release of psutil: http://code.google.com/p/psutil/ === About === psutil is a module providing an interface for retrieving information on all running processes and system utilization (CPU, memory, disks, network, users) in a portable way by using Python. It currently supports Linux, Windows, OSX, FreeBSD and Sun Solaris, both 32-bit and 64-bit, with Python versions from 2.4 to 3.3 by using a single code base. === New features === This new release finally includes support for Sun Solaris systems! I wish to thank Justin Venus who first wrote a prototype in Cython which I then converted in C (full story here: https://code.google.com/p/psutil/issues/detail?id=18). Complete list of bugfixes and enhancements is here: https://psutil.googlecode.com/hg/HISTORY === Compatitility notes === There's a couple of things you may want to know in terms of backward compatibility: * Process.get_connections() 'status' field is no longer a string but a constant object (psutil.CONN_*) * Process.get_connections() 'local_address' and 'remote_address' fields have been renamed to 'laddr' and 'raddr' * psutil.network_io_counters() has been renamed to psutil.net_io_counters() There are still aliases for the old names. They will issue a DeprecationWarning though. === Links === * Home page: http://code.google.com/p/psutil * Source tarball: http://psutil.googlecode.com/files/psutil-1.0.0.tar.gz * API Reference: http://code.google.com/p/psutil/wiki/Documentation Please try out this new release and let me know if you experience any problem by filing issues on the bug tracker. Thanks in advance and hooray for the new Solaris support! ;-) All the best, --- Giampaolo Rodola' http://code.google.com/p/pyftpdlib/ http://code.google.com/p/psutil/ http://code.google.com/p/pysendfile/
