Tiffany - Read/Write Multipage-Tiff with PIL without PIL ======================================================== Tiffany stands for any tiff. The tiny module solves a large set of problems, has no dependencies and just works wherever Python works. Tiffany was developed in the course of the *DiDoCa* project and will always appear on PyPi. Version 0.6.1 ------------- This version uses the new int.from_bytes/to_bytes methods from python3.2 and emulates them on python2.6/2.7 . This migration was tested using pytest. Tiffany is quite unlikely to change anymore until user requests come, or I get better test data: Testing with larger tiff files ------------------------------ The implementation right now copies data in one big chunk. I would like to make that better/not limited by memory. For that, I need a tiff file that is a few megabytes big. Can somebody please send me one? Extending Tiffany? ------------------ I'm also thinking of - an interface to Qt (without adding a dependency) - a command line interface, to make tiffany into a new tiff tool, - support for other toolkits that need to handle tiff files. Ideas about this are most welcome. Please let me know if this stuff works for you, and send requests to <tismer(a)stackless.com> or use the links in the bitbucket website: https://bitbucket.org/didoca/tiffany cheers -- Chris -- Christian Tismer :^)<mailto:tismer@stackless.com> tismerysoft GmbH : Have a break!

PyDev 2.6.0 Released
by Fabio Zadrozny 28 Jun '12

28 Jun '12

Hi All, PyDev 2.6.0 has been released Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com Release Highlights: ------------------------------- Interactive console: * It's now possible to use the interactive console attached to a debug session. (patch from Hussain Bohra) To use this feature either right-click a frame in the debug view and choosing PyDev > Debug console or create a new Interactive console as usual (Ctrl+Alt+Enter and choose 'PyDev Debug Console' -- but note that this option will only be enabled when in a debug session with a selected frame in the Debug view. * Fixed issue where completions from the console did not work properly with '%' because quoting was not being properly done. * Fixed issue where the execfile() redefinition in the PyDev console did not use the proper globals * When launching interactive console, PYTHONPATH order is properly kept (patch from James Blackburn). * Fix pasting into the middle of the console (patch from James Blackburn). * For paste, only go to the end of the line if the cursor isn't in range (patch from James Blackburn). PyUnit: * Improved preferences page configuration (links shown to add options). * Improved test discovery in PyDev PyUnit runner (exclude/include files/tests options added). Jython: * print may be used in dotted names as Jython requires for grammars 2.4 and 2.5. Others: * In a build, PyDev could end up reading the contents of files unrelated to Python. * Django project startup compatible with django 1.4. * Assignments to builtins when in the class-level no longer generate a warning. * Fixed issue starting new thread in the debugger (fix for paste/waitress). * Fixed error configuring interpreter if os.path was not present. * Fixed issue when configuring interpreter which has unicode characters in the PYTHONPATH. * When searching for external files, also take a look at the configured projects, as it may be that the file should actually be found in an external source folder. * Fixed issues getting marker on files with a dirty editor and where we could end up getting markers from other files. * The scripting output console is not shown unless there's actually some output to show. * A bunch of other minor fixes. 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 Appcelerator http://appcelerator.com/ Aptana http://aptana.com/ PyDev - Python Development Environment for Eclipse http://pydev.org http://pydev.blogspot.com

[RELEASED] Python 3.3.0 beta 1
by Georg Brandl 26 Jun '12

26 Jun '12

On behalf of the Python development team, I'm happy to announce the first beta release of Python 3.3.0. This is a preview release, and its use is not recommended in production settings. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. Major new features and changes in the 3.3 release series are: * PEP 380, syntax for delegating to a subgenerator ("yield from") * PEP 393, flexible string representation (doing away with the distinction between "wide" and "narrow" Unicode builds) * A C implementation of the "decimal" module, with up to 80x speedup for decimal-heavy applications * The import system (__import__) now based on importlib by default * The new "lzma" module with LZMA/XZ support * PEP 397, a Python launcher for Windows * PEP 405, virtual environment support in core * PEP 420, namespace package support * PEP 3151, reworking the OS and IO exception hierarchy * PEP 3155, qualified name for classes and functions * PEP 409, suppressing exception context * PEP 414, explicit Unicode literals to help with porting * PEP 418, extended platform-independent clocks in the "time" module * PEP 412, a new key-sharing dictionary implementation that significantly saves memory for object-oriented code * PEP 362, the function-signature object * The new "faulthandler" module that helps diagnosing crashes * The new "unittest.mock" module * The new "ipaddress" module * The "sys.implementation" attribute * A policy framework for the email package, with a provisional (see PEP 411) policy that adds much improved unicode support for email header parsing * A "collections.ChainMap" class for linking mappings to a single unit * Wrappers for many more POSIX functions in the "os" and "signal" modules, as well as other useful functions such as "sendfile()" * Hash randomization, introduced in earlier bugfix releases, is now switched on by default In total, almost 500 API items are new or improved in Python 3.3. For a more extensive list of changes in 3.3.0, see http://docs.python.org/3.3/whatsnew/3.3.html (*) To download Python 3.3.0 visit: http://www.python.org/download/releases/3.3.0/ Please consider trying Python 3.3.0 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy! (*) Please note that this document is usually finalized late in the release cycle and therefore may have stubs and missing entries at this point. -- Georg Brandl, Release Manager georg at python.org (on behalf of the entire python-dev team and 3.3's contributors)

The tiny module solves a large set of problems, has no dependencies and just works wherever Python works. Tiffany was developed in the course of the *DiDoCa* project and will always appear on PyPi. Version 0.6 ----------- This is a compatibility update for Python 3.2. Tiffany now works on Python 2.6, 2.7 and 3.2. This version also reduces the needed PIL files to only four. The same files work for python2 and python3. You can help me by sending some tiff files with different encoding and larger file size for testing. I'm also thinking of - an interface to Qt (without adding a dependency) - a command line interface, to make tiffany into a new tiff tool, - support for other toolkits that need to handle tiff files. Ideas about this are most welcome.

[ANNOUNCE] greenlet 0.4.0
by Ralf Schmitt 21 Jun '12

21 Jun '12

Hi, I have uploaded greenlet 0.4.0 to PyPI: http://pypi.python.org/pypi/greenlet What is it? ----------- The greenlet module provides coroutines for python. coroutines allow suspending and resuming execution at certain locations. concurrence[1], eventlet[2] and gevent[3] use the greenlet module in order to implement concurrent network applications. Documentation can be found here: http://greenlet.readthedocs.org The code is hosted on github: https://github.com/python-greenlet/greenlet Changes in version 0.4.0 ------------------------ The NEWS file lists these changes for release 0.4.0: * Greenlet has an instance dictionary now, which means it can be used for implementing greenlet local storage, etc. However, this might introduce incompatibility if subclasses have __dict__ in their __slots__. Classes like that will fail, because greenlet already has __dict__ out of the box. * Greenlet no longer leaks memory after thread termination, as long as terminated thread has no running greenlets left at the time. * Add support for debian sparc and openbsd5-sparc64 * Add support for ppc64 linux * Don't allow greenlets to be copied with copy.copy/deepcopy * Fix arm32/thumb support * Restore greenlet's parent after kill * Add experimental greenlet tracing Many thanks to Alexey Borzenkov, who spent a lot of time on this release and everyone else that helped make this release happen. [1] http://opensource.hyves.org/concurrence/ [2] http://eventlet.net/ [3] http://www.gevent.org/ -- Cheers Ralf Schmitt
