Wanted: New Python Success Stories
by Stephan Deibel March 29, 2005

March 29, 2005

Hi, O'Reilly Associates is going to be printing volume III of the Python Success Stories series in June and I'm looking for submissions of new stories. The stories have been quite valuable for people introducing Python to new users and companies. The deadline for me to receive stories for editing is May 1st and the deadline for the final edited, approved story going to O'Reilly is June 1st. The existing stories are online here: http://pythonology.org/success There's more info about writing one here: http://pythonology.org/successguide The biggest hurdle is usually getting approval from the company to write about Python. It may require some educating about open source to get past rules against endorsing commercial products (which Python obviously isn't). If you have any questions, please let me know. Thanks, Stephan Deibel Pythonology.com

ANN: BigDecimal - decimal arithmetic on very large intergers
by casevh＠comcast.net March 27, 2005

March 27, 2005

BigDecimal is a Python class that supports decimal arithmetic on very large integers. BigDecimal was inspired by the posting of BigDec to c.l.py by Tim Peters. BigDecimal implements all the commonly used integer methods. (It doesn't implement any of the binary/shifting operations.) It has been optimized for performance. It uses a 4x4 Toom-Cook algorithm for multiplication and a new, very fast, division algorithm. If GMPY is available, it will be automatically used. Performance examples, computing the decimal represendation of the 42nd Mersenne prime: 2**25964951 - 1 Tim Peter's posting to c.l.py: 13 minutes 41 seconds BigDecimal: 59 seconds BigDecimal w/gmpy: 10 seconds The first released version is availabe at http://home.comcast.net/~casevh

ANN: Amara XML Toolkit 1.0b1
by Uche Ogbuji March 27, 2005

March 27, 2005

http://uche.ogbuji.net/tech/4Suite/amara ftp://ftp.4suite.org/pub/Amara/ Changes in this release: * Improve mutation API. Results in at least one backwards compat break: node.xml_element(qname [, namespace]) rather than node.xml_element(namespace, qname) * Add binderytools.create_document * Fix support for doctype declarations, PIs and comments * Improve re-serialization API, including better support for 4Suite writers (and some reduction of the direct need for those) * Fix processing instructions, comments and doctype declaration bugs * Numerous bug fixes, demo and test updates Amara XML Toolkit is a collection of Python tools for XML processing-- not just tools that happen to be written in Python, but tools built from the ground up to use Python idioms and take advantage of the many advantages of Python. Amara builds on 4Suite [http://4Suite.org], but whereas 4Suite focuses more on literal implementation of XML standards in Python, Amara focuses on Pythonic idiom. It provides tools you can trust to conform with XML standards without losing the familiar Python feel. The components of Amara are: * Bindery: data binding tool (a very Pythonic XML API) * Scimitar: implementation of the ISO Schematron schema language for XML; converts Schematron files to Python scripts * domtools: set of tools to augment Python DOMs * saxtools: set of tools to make SAX easier to use in Python * Flextyper: user-defined datatypes in Python for XML processing There's a lot in Amara, but here are highlights: Amara Bindery: XML as easy as py -------------------------------- Bindery turns an XML document into a tree of Python objects corresponding to the vocabulary used in the XML document, for maximum clarity. For example, the document <monty> <python spam="eggs">What do you mean "bleh"</python> <python ministry="abuse">But I was looking for argument</python> </monty> Becomes a data structure such that you can write binding.monty.python.spam In order to get the value "eggs" or binding.monty.python[1] In order to get the value "But I was looking for argument". There are other such tools for Python, and what makes Anobind unique is that it's driven by a very declarative rules-based system for binding XML to the Python data. You can register rules that are triggered by XPattern expressions specialized binding behavior. It includes XPath support and supports mutation. Bindery is very efficient, using SAX to generate bindings. Scimitar: Schematron for Pytthon -------------------------------- Merged in from a separate project, Scimitar is an implementation of ISO Schematron that compiles a Schematron schema into a Python validator script. You typically use scimitar in two phases. Say you have a schematron schema schema1.stron and you want to validate multiple XML files against it, instance1.xml, instance2.xml, instance3.xml. First you run schema1.stron through the scimitar compiler script, scimitar.py: scimitar.py schema1.stron The generated file, schema1.py, can be used to validate XML instances: python schema1.py instance1.xml Which emits a validation report. Amara DOM Tools: giving DOM a more Pythonic face ------------------------------------------------ DOM came from the Java world, hardly the most Pythonic API possible. Some DOM-like implementations such as 4Suite's Domlettes mix in some Pythonic idiom. Amara DOM Tools goes even further. Amara DOM Tools feature pushdom, similar to xml.dom.pulldom, but easier to use. It also includes Python generator-based tools for DOM processing, and a function to return an XPath location for any DOM node. Amara SAX Tools: SAX without the brain explosion ------------------------------------------------ Tenorsax (amara.saxtools.tenorsax) is a framework for "linerarizing" SAX logic so that it flows more naturally, and needs a lot less state machine wizardry. License ------- Amara is open source, provided under the 4Suite variant of the Apache license. See the file COPYING for details. Installation ------------ Amara requires Python 2.3 or more recent and 4Suite 1.0a4 or more recent. Make sure these are installed, unpack Amara to a convenient location and run python setup.py install -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com Use CSS to display XML, part 2 - http://www-128.ibm.com/developerworks/edu/x-dw-x-xmlcss2-i.html Writing and Reading XML with XIST - http://www.xml.com/pub/a/2005/03/16/py-xml.html Introducing the Amara XML Toolkit - http://www.xml.com/pub/a/2005/01/19/amara.html Be humble, not imperial (in design) - http://www.adtmag.com/article.asp?id=10286 Querying WordNet as XML - http://www.ibm.com/developerworks/xml/library/x-think29.html Packaging XSLT lookup tables as EXSLT functions - http://www.ibm.com/developerworks/xml/library/x-tiplook2.html

ANN: pyparsing-1.3 released
by Paul McGuire March 26, 2005

March 26, 2005

I'm happy to announce that 1) pyparsing has been pretty stable for the past 6 months (the last formal release 1.2.2 was last September), and 2) I finally found the time to put together a new release, version 1.3. This release also includes all of the enhancements I posted to CVS last fall as version 1.2.3, but never formally released. Here are some of the major new features and bug-fixes: Version 1.3 - March, 2005 ---------------------------------- - Added new Keyword class, as a special form of Literal. Keywords must be followed by whitespace or other non-keyword characters, to distinguish them from variables or other identifiers that just happen to start with the same characters as a keyword. For instance, the input string containing "ifOnlyIfOnly" will match a Literal("if") at the beginning and in the middle, but will fail to match a Keyword("if"). Keyword("if") will match only strings such as "if only" or "if(only)". (Berteun Damman requested this on comp.lang.python - great idea!) - Added setWhitespaceChars() method to override the characters to be skipped as whitespace before matching a particular ParseElement. Also added the class-level method setDefaultWhitespaceChars(), to allow users to override the default set of whitespace characters (space, tab, newline, and return) for all subsequently defined ParseElements. (Inspired by Klaas Hofstra's inquiry on the Sourceforge pyparsing forum.) - Added helper parse actions to support some very common parse action use cases: .. replaceWith(replStr) - replaces the matching tokens with the provided replStr replacement string; especially useful with transformString() .. removeQuotes - removes first and last character from string enclosed in quotes (note - NOT the same as the string strip() method, as only a single quote character is removed at each end) - Added copy() method to ParseElement, to make it easier to define different parse actions for the same basic parse expression. (Note, copy is implicitly called when using setResultsName().) (The following changes were posted to CVS as Version 1.2.3 - October-December, 2004) - Added support for Unicode strings in creating grammar definitions. (Big thanks to Gavin Panella!) - Added constant alphas8bit to include the following 8-bit characters: ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýþ - Added srange() function to simplify definition of Word elements, using regexp-like '[A-Za-z0-9]' syntax. This also simplifies referencing common 8-bit characters. - Fixed bug in Dict when a single element Dict was embedded within another Dict. (Thanks Andy Yates for catching this one!) - Added 'formatted' argument to ParseResults.asXML(). If set to False, suppresses insertion of whitespace for pretty-print formatting. Default equals True for backward compatibility. - Added setDebugActions() function to ParserElement, to allow user-defined debugging actions. - Added support for escaped quotes (either in \', \", or doubled quote form) to the predefined expressions for quoted strings. (Thanks, Ero Carrera!) - Minor performance improvement (~5%) converting "char in string" tests to "char in dict". (Suggested by Gavin Panella, cool idea!)
