XPY 0.1.0 released
by Juan David Ibáñez Palomar 06 Dec '02

Download from http://sourceforge.net/projects/lleu/ XPY stands for XPath PYthon, it is a tool to transform XML documents to something else. It is inspired by XSLT, the main difference is that the transformation language is Python. First the XML document is loaded as an extended DOM tree, where each node has new methods that begin with the prefix 'xpy_', these methods define a higher level API used to transform the tree. We will call this extended tree an XPY tree. Once it is loaded it can be transformed with the standard DOM API or with the XPY one. The XPY API lets to use XPath expressions to match nodes in the tree, then Python functions are applied to these nodes. We will call rules to these Python functions, following the terminology from XSLT. Typically there are one or more templates (XML documents) which are transformed by rules (Python functions) using the XPY API. To generate the final tree these rules use data that could be stored in a database, for example. So we have three different elements: the presentation, the logic and the content, achieving a better separation between them than most tools. Each element is implemented using the best posible way: a general purpose programming language for the logic, Python; a description language for the presentation, XHTML for example; and a database for the content (a relational database, the ZODB, etc..). The main advantage of this separation is scalability, it is possible to refactor the code without limits, unlike the most commonly used template languages; and the source looks much more like the final result.

BayPIGgies: Silicon Valley-San Francisco Bay Area Python Users Group When: December 11, 2002 @ 7:30pm Where: Stanford University, Palo Alto, CA Agenda: Newbies' Nite Speaker: (everyone!) Due to popular demand, we are having another Newbie Night (e.g. April 2002). This is the chance for all Python programmers to bring their friends and colleagues who should hear about Python. It is also for those who want to or are picking up Python and have questions! We will have a good number of Python experts who will try and help you out. Perl and Java experts are welcome too, as many Python developers also have experience there and can give you an honest comparison. The format is this: Wesley (or Danny) will give just a short half-hour intro presentation on Python to beginners followed by a quick demo, and then we will open it up to everyone for Q&A. Mingling and networking will bring our meeting to a glorious conclusion. :-) # NOTE: the next meeting on January 8, 2003 will be not be at the usual # place... stay tuned for a location update. # Call For Talks: We are actively seeking speakers for BayPIGgies! If you would like to give a talk at one of our 2003 meetings (any Python related topic), contact us to coordinate! more info including directions: http://www.baypiggies.net hope to see some of you next Wednesday! -wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall PTR, � 2001 http://starship.python.net/crew/wesc/cpp/ Silicon Valley-San Francisco Bay Area Python Users Group (BayPIGgies) http://deirdre.org/baypiggies wesley.j.chun :: wesc at deirdre.org cyberweb.consulting : henderson, nv : cyberweb at rocketmail.com http://www.roadkill.com/~wesc/cyberweb/

ANNOUNCE: SCons 0.09 is now available
by Steven Knight 06 Dec '02

06 Dec '02

SCons is a software construction tool (build tool, or make tool) written in Python. It is based on the design which won the Software Carpentry build tool competition in August 2000. Version 0.09 of SCons has been released and is available for download from the SCons web site: http://www.scons.org/ Or through the download link at the SCons project page at SourceForge: http://sourceforge.net/projects/scons/ RPM and Debian packages and a Win32 installer are all available, in addition to the traditional .tar.gz and .zip files. This is a big release that took a long time to produce, mainly due to the addition of the major new Repository feature. WHAT'S NEW IN THIS RELEASE? IMPORTANT: Release 0.09 contains the following interface changes: - The SetCommandHandler() function has been superceded by new SPAWN, SHELL and ESCAPE construction variables. - SCons now exits with an error message if any source or implicit dependency files for a target do not exist and have no Builder. - The 'lib' tool (the Microsoft library archiver) has had its name changed to 'mslib'. This release adds the following features: - A new Repository() method and -Y command-line option support building from source or target files in common repositories. - A new Prepend() Environment method appends values to the beginning of construction variables. - Support for the Intel Fortran Compiler (ifl.exe) has been added. - New messages tell when SCons is "Reading SConscript files ...," "done reading SConscript files," "Building targets," and "done building targets." A new -Q option supresses these. - Shared-object prefixes and suffixes may be specified independently usng new $SHOBJPREFIX and $SHOBJSUFFIX construction variables. - A new ParseConfig() command supports modifying an environment based on parsing output from a *-config command. - New EnsurePythonVersion() and EnsureSConsVersion() functions. - SCons now checks dynamically for the existence of utilities with which to initialize Environments by default. - SCons now supports Microsoft VC++ precompiled header (.pch) files, debugger (.pdb) files, and resource (.rc) files. - The File() and Dir() methods can now take a path-name string as the starting directory. - A new Options() object makes it easier to extend SCons' command- line arguments. - A new SetContentSignatureType() function allows use of file timestamps instead of MD5 signatures. The following fixes have been added: - Construction variable substition on scanner directories (in CPPPATH, F77PATH, LIBPATH, etc.) is now supported. - $$ in a string is now passed through as $. - File names and command lines with spaces and other odd characters are now fully supported. - The "lib" Tool (Microsoft library archiver) now supports long command lines. - Auto-deduced target file names now end up in the same directory as their source files. - Source files specified on the command line are no longer removed. - Using Default() with the -U option now fails gracefully. - SCons no longer unlinks files in certain situations when the -n option is used. - SCons now issues a warning when -c can't remove a target. - File names like '#/../foo' are now interpreted correctly on Win32 systems. - SCons now supplies an error message if there are no command-line or Default() targets specified. - The $ASPPCOM variable has been fixed for the GNU assembler. - The -U option is now properly case-insensitive on Win32 systems. - Using the -j option with multiple targets is now more robust. - SCons now handles a corrupt .sconsign file robustly. - Access and modification times of files in a BuildDir now match the corresponding source file, even without hard links. - Dependencies now propogate succesfully through Alias targets. - Fix unnecessary rebuilds cased by differently-ordered targets on case-insensitive systems. - Dependency scans when $LIBS is overridden now work properly. - Build errors in a list of build commands no longer cause the display of an overly-verbose stack trace. Performance has been improved as follows: - Unnecessary Scanner calls have been eliminated when a file doesn't exist. - The $_CPPINCFLAGS, $_F77INCFLAGS, $_LIBFLAGS and $_LIBDIRFLAGS variables are now generated on-demand, not with every command invocation. - Command execution overhead has been reduced by using the Python os.sytem() function instead of fork() and exec(). The following changes have been made to the SCons packaging: - New scons-local packages make it easy to ship SCons as a stand-alone build tool in other software packages. The documentation has been improved: - Documented the fact that Builder calls return Node objects. - Documented all new features, of course... ABOUT SCONS Distinctive features of SCons include: - a global view of all dependencies; no multiple passes to get everything built properly - configuration files are Python scripts, allowing the full use of a real scripting language to solve difficult build problems - a modular architecture allows the SCons Build Engine to be embedded in other Python software - the ability to scan files for implicit dependencies (#include files); - improved parallel build (-j) support that provides consistent build speedup regardless of source tree layout - use of MD5 signatures to decide if a file has really changed; no need to "touch" files to fool make that something is up-to-date - easily extensible through user-defined Builder and Scanner objects - build actions can be Python code, as well as external commands An scons-users mailing list is available for those interested in getting started using SCons. You can subscribe at: http://lists.sourceforge.net/lists/listinfo/scons-users Alternatively, we invite you to subscribe to the low-volume scons-announce mailing list to receive notification when new versions of SCons become available: http://lists.sourceforge.net/lists/listinfo/scons-announce ACKNOWLEDGEMENTS Thanks to Chad Austin, Matt Balvin, Steve Leblanc, Jeff Petkau and sam th for their contributions to this release. Special thanks to Charles Crain for heavy work on the Repository feature, and Anthony Roach for a tremendous number of bug fixes and other features. On behalf of the SCons team, --SK

ANN: PAGE-2.2c - Python Automatic GUI Generator
by Don Rozenberg 06 Dec '02

06 Dec '02

PAGE-2.2c - Python Automatic GUI Generator What is PAGE? ----------- PAGE is an automatic GUI generator which bears a resemblance to Visual Basic. It allows one to easily create GUI window containing a selection of Tk and Tix widgets and bind actions associated with events in those widgets with a straight-forward, visual paradigm. It is a Tcl/Tk/Tix program that generates a Python module that realizes the desired GUI. Further, it supports rework in that one can generate a Python GUI module, debug it in the Python space, and yet be able to return to the Tcl/Tk realm to modify or update the appearance of the GUI or change the bindings on the widgets What's new? ----------- Fixed numerous problems in PAGE-2.2c. Fixed and documented the generation of menus. Fixed and documented the bindings window so now it is highly usable. Removed preferences that were hard to fathom. Added Python colorization to some of the PAGE windows. Rewrote p2t. It is now much more solid than previously and improves rework capabilities. p2t.py converts a Python GUI generated with PAGE into a tcl module that can be opened by PAGE. Included Vrex as an example. This is a very useful visual program for developing and checking regular expressions. It is similar to Visual REGEXP. Included an extension package that enhances python-mode.el in executing a python module with both the interpreter and debugger. It also allows one to run PyChecker from emacs. Improved the documentation.
