Jinja 1.1 Released
by Armin Ronacher June 2, 2007

June 2, 2007

Jinja 1.1 Released ================== Jinja 1.1 codenname sinka is out! And with more changes then ever. Here a small summary of the new features and improvements: - blocks now support ``{{ super() }}`` to render the parent output. - the template lexer keeps not track of brace, parenthesis and bracket balance in order to not break variable tags apart if they are configured to look like this: ``${expr}``. This also fixes the problem with nested dicts in variable expressions. - added whitespace management system for the template designer. - many new filters and helpers such as `lipsum`, `batch`, `slice`, `sum`, `abs`, `round`, `striptags` and others. - reimplemented Buffet plugin so that you can use Jinja in pylons. - added optional C-implementation of the context baseclass. - it's now possible to stream templates. - reworked loader layer. All the cached loaders now have "private" non cached baseclasses so that you can easily mix your own caching layers in. - added `MemcachedLoaderMixin` and `MemcachedFileSystemLoader` contributed by Bryan McLemore. - many new unittests, bugfixes and improvements. The whole list of changes can be found in the `changelog`_. Get it while it's hot from the `cheeseshop`_. .. _changelog: http://jinja.pocoo.org/documentation/changelog#version-1-1 .. _cheeseshop: http://cheeseshop.python.org/pypi/Jinja/1.1

itools 0.15.5 released
by "J. David Ibáñez" June 1, 2007

June 1, 2007

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.i18n itools.vfs itools.cms itools.ical itools.web itools.csv itools.pdf itools.workflow itools.datatypes itools.rss itools.xhtml itools.gettext itools.schemas itools.xliff itools.handlers itools.stl itools.xml itools.html itools.tmx itools.http itools.uri This release has a single feature enhancement worth to comment: now "itools.cms" indexes the content of RTF files (for this to work the command "unrtf" must be installed). Also important is the requirement to run the "icms-update" script on existing instances of "itools.cms". This will just re-index the catalog (it is needed because of a little internal change on the "username" field). Still in "itools.cms", there have been a number of user interface tweaks here and there, but most notably in the tracker. There is a change in the "itools.catalog" API worth to comment. Now when the method search is called without any arguments, all indexed documents are returned. Also, the method "get_physical_path" has been added to all handlers. And path objects have gained the method "get_name". Packages and scripts that have seen minor fixes and improvements are: itools.catalog, itools.pdf, itools.web, itools.xml, isetup-build, icms-update and icms-restore. Credits: - Luis Belmar-Letelier worked on the tracker; - Hervé Cauwelier implemented the RTF indexer and worked on the user interface of itools.cms; - J. David Ibáñez fixed bugs here and there; - Henry Obein fixed bugs on RML (itools.pdf); - Sylvain Taverne fixed some bugs; Resources --------- Download http://download.ikaaro.org/itools/itools-0.15.5.tar.gz Home http://www.ikaaro.org/itools Mailing list http://mail.ikaaro.org/mailman/listinfo/itools Bug Tracker http://bugs.ikaaro.org/ -- J.

PySWIP 0.1.3 released
by yuce June 1, 2007

June 1, 2007

I am pleased to announce the 0.1.3 version of PySWIP. PySWIP is a GPL'd Python - SWI-Prolog bridge which enables querying SWI-Prolog in your Python programs. PySWIP includes both an (incomplete) SWI-Prolog foreign language interface and a utity class that makes it easy querying SWI-Python. Since it uses SWI-Prolog as a shared library and ctypes to access it, PySWIP doesn't require compilation to be installed. This version breaks the compatibility with previous versions. Example: >>> from pyswip.prolog import Prolog >>> prolog = Prolog() >>> prolog.assertz("father(michael,john)") [{}] >>> prolog.assertz("father(michael,gina)") [{}] >>> list(prolog.query("father(michael,X)")) [{'X': 'john'}, {'X': 'gina'}] >>> for soln in prolog.query("father(X,Y)"): ... print soln["X"], "is the father of", soln["Y"] ... michael is the father of john michael is the father of gina Foreign Functions Example: Since version 0.1.3 of PySWIP, it is possible to register a Python function as a Prolog predicate through SWI-Prolog's Foreign Function Interface. Here's an example: from pyswip.prolog import Prolog from pyswip.easy import registerForeign, getAtomChars def hello(t): print "Hello,", getAtomChars(t) return True hello.arity = 1 registerForeign(hello) prolog = Prolog() prolog.assertz("father(michael,john)") prolog.assertz("father(michael,gina)") list(prolog.query("father(michael,X), hello(X)")) Outputs: Hello, john Hello, gina Requirements: * Python 2.3 and higher. * ctypes 0.9.9.9 and higher. * SWI-Prolog 5.6.x and higher (most probably other versions will also work). * libpl as a shared library. * Works on Linux and Win32, should work for all POSIX. Changes since version 0.1.2: * Renamed `pyswip/util.py` to `pyswip/prolog.py`. * New module `pyswip.easy`. * Now it is possible to register a Python function as a Prolog predicate through SWI-Prolog's Foreign Function Interface. * Additions to the core library. * Added example, *register foreign* which shows how to register a Python function as an SWI-Prolog predicate. * Added example, *Towers of Hanoi* PySWIP homepage is at: http://code.google.com/p/pyswip Downloads at: http://code.google.com/p/pyswip/downloads/list Discussion Group is at: http://groups.google.com/group/pyswip Regards, Yuce Tekol yucetekol [at] gmail [dot] com>

bug fix for scalar package
by uymqlp502＠sneakemail.com June 1, 2007

June 1, 2007

A few days ago (May 28th), I announced release 1.3 of my scalar package. Unfortunately, it had a bug in the "format" function for output, but I just fixed it in release 1.3.1. My apologies to anyone who downloaded version 1.3. http://RussP.us/scalar.htm
