ANN: dmath 0.9 - Math routines for the Decimal type
by Brian Beck 25 Sep '06

25 Sep '06

Hi all, I'm pleased to announce the first release of my new library, dmath. It is available under the MIT/X11 license. Download ======== Cheese Shop: http://cheeseshop.python.org/pypi/dmath/0.9 Google Code: http://code.google.com/p/dmath/ What is dmath? ============== dmath provides the standard math routines for Python's arbitrary-precision Decimal type. These include acos, asin, atan, atan2, ceil, cos, cosh, degrees, e, exp, floor, golden_ratio, hypot, log, log10, pi, pow, radians, sign, sin, sinh, sqrt, tan, and tanh. How is it different from decimalfuncs? ====================================== dmath has the complete set of math routines (not just a subset), it's faster (from what I can tell), doesn't require its own precision-setting method, and is MIT instead of GPL licensed. About this release: =================== This is the first release and I'm calling this release 0.9 because it just needs some testing and maybe some speed improvements, otherwise it's ready to use. There is currently some work being done in Python sandbox/trunk to convert the decimal module to C, and maybe they'll include fast versions of all these routines. You can follow development details and announcements on my blog here: http://blog.case.edu/bmb12/ How do I use it? ================= Use it just like math and cmath, but make sure you give it Decimals: >>> from dmath import * >>> from decimal import Decimal as D, getcontext >>> getcontext().prec = 50 >>> asin(D(1)) Decimal("1.5707963267948966192313216916397514420985846996876") >>> golden_ratio() Decimal("1.6180339887498948482045868343656381177203091798058") -- Brian Beck Adventurer of the First Order

[ANN] tperimeter 1.110 Released And Available
by Tim Daneliuk 25 Sep '06

25 Sep '06

'tperimeter' Version 1.110 is released and available at: http://www.tundraware.com/Software/tperimeter/ What's New ---------- This is the initial public release of 'tperimeter' What Is 'tperimeter'? --------------------- Have you ever been away from the office and needed, say, ssh access to your system? Ooops - you can't do that because in your zealous pursuit of security, you set your tcp wrappers to prevent outside access to all but a select group of hosts. Worse still, everywhere you go, your local IP address changes so there is no practical way to open up the wrappers for this situation. 'tperimeter' is a dynamic tcp wrapper control system that gives you (limited) remote control of your tcp wrapper configuration. It does this via a web interface that you've (hopefully) secured with https/SSL. You just log in, specify your current IP address and one of the services you want to access. 'tperimeter' will then briefly open a hole in your wrappers long enough to let you in. It then automatically closes the hole again. Voila! Remote access to your system, wherever you are. You get much of the facility of a VPN or so-called "port knocking" without most of the aggravation. As a side benefit, 'tperimeter' will also simplify management of your standard /etc/hosts.allow tcp wrapper control file. 'tperimeter' is written in python, shell script, and html. It is very small and easy to maintain. It was developed and tested on FreeBSD 4.x, and apache 1.3, but should run with very minor (or no) modification on most Unix-like systems like Linux or Mac OS X hosts. It comes complete with documentation in html, pdf, dvi, and Postscript formats. There is no licensing cost for individual non-commercial use. -- ---------------------------------------------------------------------------- Tim Daneliuk tundra(a)tundraware.com PGP Key: http://www.tundraware.com/PGP/

Hello! I'm pleased to announce the 0.7.1 release of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.7.1 News and changes: http://sqlobject.org/docs/News.html What's New ========== Features & Interface -------------------- * Added support for psycopg2 and MSSQL. * Added TimeCol. * RelatedJoin and SQLRelatedJoin objects have a createRelatedTable keyword argument. * Implemented RLIKE (regular expression LIKE). Small Features -------------- * Select over RelatedJoin. * SQLite foreign keys. * Postgres DB URIs with a non-default path to unix socket. * Allow the use of foreign keys in selects. * Implemented addColumn() for SQLite. Bug Fixes --------- * Fixed a longstanding problem with UnicodeCol - at last you can use unicode strings in .select() and .selectBy() queries. There are some limitations, though. * Cull patch (clear cache). * Synchronize main connection cache during transaction commit. * Ordering joins with NULLs. * Fixed bugs with plain/non-plain setters.

ANN: Templayer 1.4 - HTML templating library
by Ian Ward 25 Sep '06

25 Sep '06

Announcing Templayer 1.4 ------------------------ Templayer home page: http://excess.org/templayer/ Tarball: http://excess.org/templayer/templayer-1.4.tar.gz About this release: =================== This release improves integration with the Django web framework by reducing the amount of code required in Django views and by allowing use of Django forms in Templayer templates. Also, two new HTML Markup tags were added and it is now possible for flat template files (files with no layers) to be used. New in this release: ==================== - Added a django_form convenience function for using Templayer with the Django web framework's FormWrapper objects. - Added an allow_degenerate parameter to Template.__init__. If set to True then a template file that is missing a contents block will be accepted and not cause an exception to be raised. - Added a special layer name '*' that treats the entire contents of a template file as a layer. - Added two new HTML Markup elements: - ('pluralize',count,singular_markup,plural_markup) inserts singular_markup if count equals one, and plural_markup otherwise. - ('&',entity) inserts the given HTML entity where valid entity values include "gt", "#161" and "#xA9". - FileLayer.close now returns the file object to which it wrote. This simplifies the code required to use Templayer in Django view functions. - Fixed a really obvious bug in the html_href function. About Templayer =============== Templayer was created to offer an alternative to the more common ways of generating dynamic HTML: embedding code within the HTML or embedding HTML within code. Instead of mixing HTML and Python, two rich and extremely expressive languages, Templayer adds a small amount of syntax to each and keeps the two separate and coherent. Templayer is released under the GNU LGPL.

itools 0.14.3 released
by "J. David Ibáñez" 25 Sep '06

25 Sep '06

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.http itools.uri itools.cms itools.i18n itools.vfs itools.csv itools.ical itools.web itools.datatypes itools.rss itools.workflow itools.gettext itools.schemas itools.xhtml itools.handlers itools.stl itools.xliff itools.html itools.tmx itools.xml This is mostly a bug-fix release: - A new datatype for time objects has been added to itools.datatypes (#104). - Now there is some support for the HTTP layer in itools.vfs, the methods "exists", "get_mimetype", "get_mtime", "is_file" and "is_folder" and "open" work. - An important bug in itools.catalog has been fixed, now indexing of stored fields when the value is a list of byte strings works fine. - Now the method "context.come_back" (from itools.web) accepts a URI object for the "goto" parameter, not just a string. - There have been many improvements to the calendar code, both in itools.ical and itools.cms: #82, #246, #496, #507 and #509. - Fix renaming of a non-empty folder. The external editor (itools.cms) works again. Text handlers have a view to change their workflow state. Some templates (e.g. image preview) are not broken anymore in other languages than english (#502, #511). And anonymous users can reach the profile page. Credits: - Hervé Cauwelier helped with the calendar code; - Nicolas Deram kept working on the calendar and calendar related code; - J. David Ibáñez fixed bugs here and there.

CSV mailing list moved to python.org
by skip＠pobox.com 24 Sep '06

24 Sep '06

The csv mailing list originally hosted on mojam.com has been moved intact to a new home on mail.python.org. Thanks to Brad Knowles for turning the necessary knobs on mail.python.org. The list info page is at: http://mail.python.org/mailman/listinfo/csv For a fairly short period of time the old list address and web pages will redirect to the new location. The csv mailing list was originally created to support the development of a csv module for Python (available since 2.3). It now serves mostly as a low-volume place to discuss extensions to the module, offer assistance to users, and as a place to report problems. -- Skip Montanaro - skip(a)pobox.com - http://www.mojam.com/ "In China today, Bill Gates is Britney Spears.
