Python code beautifier
by Martin Gebert July 17, 2002

July 17, 2002

Hi together! The GNU tool source-highlight, a code beautifier by Lorenzo Bettini that produces syntax highlighted HTML and XHTML documents from source code, now recognizes Python, too. You can get it here: http://www.gnu.org/software/src-highlite/ The Python scanner was written by me and still needs some verifying; so if you find bugs (I hope not...), have suggestions or are simply full of praise ;-) you can send a mail to me. I also provide a small KDE frontend for source-highlight which you can get here: http://murphy.netsolution-net.de/Ksrc2.html Have fun! Martin

pyrepl-0.7
by Michael Hudson July 17, 2002

July 17, 2002

It's taken waay to long, but I've finally released a new version of pyrepl, imaginatively called pyrepl 0.7. >From the README: This is pyrepl 0.7, a readline-a-like in Python. http://starship.python.net/crew/mwh/hacks/pyrepl.html It requires python 2.1 (or newer) with either the curses and termios modules built or pygame, and features: * sane multi-line editing * history, with incremental search * completion, including displaying of available options * a fairly large subset of the readline emacs-mode keybindings (adding more is mostly just a matter of typing) * a liberal, Python-style, license * a new python top-level * no global variables, so you can run two or more independent readers without having their histories interfering. * no hogging of control -- it should be easy to integrate pyrepl into YOUR application's event loop. * generally speaking, a much more interactive experience than readline (it's a bit like a cross between readline and emacs's mini-buffer) There are probably still a few little bugs & misfeatures, but _I_ like it, and use it as my python top-level most of the time. To get a feel for it, just execute: $ python pythoni (One point that may confuse: because the arrow keys are used to move up and down in the command currently being edited, you need to use ^P and ^N to move through the history) I seem to have forgotten to mention the prototypical new pygame console, probably one of the more interesting things in this release... Cheers, M.

ANN: Pyrex 0.3.4
by Greg Ewing July 16, 2002

July 16, 2002

Pyrex 0.3.4 is now available: http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/ Bug fixes: - Runtime crash when using * or ** args in a method of an extension type fixed. - Compiler crash when using default argument values in a method of a Python class. Enhancements: - Type slots filled with functions from outside the extension module are now initialised dynamically, which should eliminate at least some of the "initialiser is not constant" problems experienced on Windows. - On Windows, __declspec(dllexport) is now used for the module init func declaration (or should be -- I haven't tested this). What is Pyrex? -------------- Pyrex is a new language for writing Python extension modules. It lets you freely mix operations on Python and C data, with all Python reference counting and error checking handled automatically. -- Greg Ewing, Computer Science Dept, University of Canterbury, Christchurch, New Zealand http://www.cosc.canterbury.ac.nz/~greg

spyce v1.1.29
by Rimon Barr July 16, 2002

July 16, 2002

Most important changes since last posting (v1.1.22) - should now work on every python version from 1.5.2 and up (Python 2.1 and up recommended, for nested_scoping). - bug fixes to file-based session handler - -O switch added to handle multiple files - Windows installer - improved line compaction algorithm - fcgi implemented on Windows too (Apache 2.0 mod_fcgi expected soon) - cgi stdout forced to binary mode on Windows - documenation reorganized and split up onto multiple pages - live examples on sourceforge - lots of other minor improvements ---------- SPYCE - Server Python Pages SPYCE is a webserver plugin that supports simple and efficient Python-based dynamic HTML scripting. Those who like Python and are familiar with JSP, or PHP, or ASP, should have a look at this engine. It allows one to generate dynamic HTML content just as easily, using Python for the dynamic parts. Its modular design makes it very flexible and extensible. It supports FastCGI, CGI and mod_python to plugin into Apache and most other webservers. It can also be used as a command-line utility for HTML pre-processing. v1.1.29 released on 16 July 2002. Get it at: http://spyce.sourceforge.net ---------- Partial change log: v1.1.29 documentation split up rpm is now noarch v1.1.28 include.dump() now has binary option stdout changed to binary mode on windows for cgi purposes fixed session_dir handler bug on windows v1.1.27 fcgi implemented on windows too windows installer v1.1.26 fixed - nasty bug with the new module behaviour small improvements to documentation and examples improved request.uri() function v1.1.25 fixed - fcgi module broke on windows v1.1.24 line compaction improved module behaviour on include.spyce() defined v1.1.23 lots of changes so that: it works on Python 1.5.2 now too! file-based session handler now uses pid, and file locks live examples on sourceforge v1.1.22 fixed Python v2.1.1-related bugs. improved installation process and documentation rpm more likely to succeed - uses fcgi or drops back to cgi no longer mod_python based by default ...

cx_Oracle 2.5
by Anthony Tuininga July 16, 2002

July 16, 2002

What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://computronix.com/utilities What's new? The primary focus of this release was increased performance in certain key areas, elimination of unimplemented parts of the DB-API 2.0 and increased usefulness in a threaded environment. The following list details the changes made in no particular order. 1) Added flag OPT_NoOracle7 which, if set, assumes that connections are being made to Oracle8 or higher databases; this allows for eliminating the overhead in performing this check at connect time 2) Added flag OPT_NumbersAsStrings which, if set, returns all numbers as strings rather than integers or floats; this flag is used when defined variables are created (during select statements only) 3) Added flag OPT_Threading which, if set, uses OCI threading mode; there is a significant performance degradation in this mode (about 15-20%) but it does allow threads to share connections (threadsafety level 2 according to the Python Database API 2.0); note that in order to support this, Oracle 8i or higher is now required 4) Added Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS pairs where applicable to support threading during blocking OCI calls 5) Added global method attach() to cx_Oracle to support attaching to an existing database handle (as provided by PowerBuilder, for example) 6) Eliminated the cursor method fetchbinds() which was used for returning the list of bind variables after execution to get the values of out variables; the cursor method setinputsizes() was modified to return the list of bind variables and the cursor method execute() was modified to return the list of defined variables in the case of a select statement being executed; these variables have three methods available to them: getvalue([<pos>]) to get the value of a variable, setvalue(<pos>, <value>) to set its value and copy(<var>, <src_pos>, <targ_pos>) to copy the value from a variable in a more efficient manner than setvalue(getvalue()) 7) Implemented cursor method executemany() which expects a list of dictionaries for the arguments 8) Implemented cursor method callproc() 9) Added cursor method prepare() which parses (prepares) the statement for execution; subsequent execute() or executemany() calls can pass None as the statement which will imply use of the previously prepared statement; used for high performance only 10) Added cursor method fetchraw() which will perform a raw fetch of the cursor returning the number of rows thus fetched; this is used to avoid the overhead of generating result sets; used for high performance only 11) Added cursor method executemanyprepared() which is identical to the method executemany() except that it takes a single argument which is the number of times to execute a previously prepared statement and it assumes that the bind variables already have their values set; used for high performance only 12) Added support for rowid being returned in a select statement 13) Added support for comparing dates returned by cx_Oracle 14) Integrated patch from Andre Reitz to set the null ok flag in the description attribute of the cursor 15) Integrated patch from Andre Reitz to setup.py to support compilation with Python 1.5 16) Integrated patch from Benjamin Kearns to setup.py to support compilation on Cygwin -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software.

ANNOUNCE: SCons 0.08 (Python build tool) is now available
by Steven Knight July 15, 2002

July 15, 2002

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 0.08 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. WHAT'S NEW IN THIS RELEASE? IMPORTANT: Release 0.08 contains the following interface changes: - The old feature of automatically splitting strings of file names on white space has been REMOVED. - The prefix, suffix and src_suffix arguments to the Builder() function may no longer be callable functions. - The BUILDERS construction variable should now be a dictionary that maps builder names to actions. Existing uses of lists, and the Builder() name= keyword argument, generate warnings about use of deprecated features. - The "shared" keyword argument has been removed from the Object and Library builders. Shared and static objects and libraries should now be created via the separate StaticObject, SharedObject, StaticLibrary and SharedLibrary builders. Object and Library are now synonyms for StaticObject and StaticLibrary, respectively. This release adds the following features: - New construction environment Append() and Replace() methods allow clearer manipulation of construction variables. - New functions: FindFile(), GetLaunchDir(), SetBuildSignatureType(), SideEffect(). - New command-line options: --debug=time, --implicit-deps-changed, --implicit-deps-unchanged, --warn. - New Builders: Tar. - Added a new Platform() method with support for the cygwin, os2, posix, and win32 platforms. - New "platform" and "tools" keyword arguments to Environment(). - Added a new Tool() method with support for the ar, dvipdf, dvips, g++, g77, gas, gcc, gnulink, icc, ilink, latex, lex, lib, masm, mslink, msvc, nasm, pdflatex, pdftex, tar, tex and yacc tools. - A dependency Scanner for native Fortran "include" statements, using a new "F77PATH" construction variable. - The -v option prints more specific version / build information. changes in the case of drive letters don't cause a rebuild. - The "target" argument to a Builder call may now be omitted, in which case the target(s) are deduced from the source file(s) and the Builder's specified suffix. - A new "multi" keyword argument to Builder() specifies that it's okay to call the builder multiple times for a target. - SCons now automatically falls back to using timestamps for out-of-date checks if the Python MD5 module can't be imported. - Multiple calls for a single Alias() will now append values. The following fixes have been added: - File names with multiple dots are now handled correctly. - The --implicit-cache option has been fixed if the scanner returns an empty list; no longer causes redundant rebuilds when the header file list changed; has been fixed when a file has no implicit dependencies and its source is generated. - C dependency scanning now detects #include file names with characters like '-'. - Shared libraries now use LIBS and LIBPATH for dependencies. - A build directory may now be outside of the SConstruct tree. - Shared object builds using g++ and gcc now use $CPPFLAGS, too. - A single interrupt is now guaranteed to halt SCons both when using -j and not. - Relative CPPPATH directories now work correctly when using BuildDir(). - SCons now prints an error message if a file can't be unlinked before being built, instead of just silently terminating the build. - Emitter functions' use of path names work properly using BuildDir or in subdirectories. - Fix .sconsign signature storage so that output files of one build can be safely used as input files to another build. Performance has been improved as follows: - Use our own version of the inefficient stock os.path.splitext() method. - Cache source suffix computation. - Code cleanup in MultiStepBuilder.__call__(). - Replicate some logic in scons_subst(). The following changes have been made to the SCons packaging: - Updated README instructions and setup.py code to catch an installation failure from not having distutils installed. The documentation has been updated to reflect the above changes. 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 Special thanks to Charles Crain, Jeff Petkau, Anthony Roach, Zed Shaw and Terrel Shumway for their contributions to this release.

WaselWeb
by ny_r_marquez＠yahoo.com July 13, 2002

July 13, 2002

This may interest you if have a Palm Pilot, or if you are interested in custom parsing html files. Those of you with Palm Pilots may be familiar with Weasel reader (http://sourceforge.net/projects/gutenpalm/). I really like this reader because, besides being free software, it gives the best compression that I have seen, and it allows for bookmarks to be generated on the fly as it converts from txt format to its ztxt (pdb) format. The problem for me was that the converter did not know how to handle html files. So I wrote a little Python program to do this and I called it WeaselWeb. It is licensed as free software under the GPL. If you are interested, get it from here (eventually it will be under the main Weasel project page): http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gutenpalm/gutenpalm/ There is a nice self installing package for Windows. However, the Linux version will need a little help since I do not yet have a usable Linux machine. I would like to eventually creaet a standalone version for Linux as well. (If some one would like to help with this, please be my guest.) Any way, I hope you enjoy it. -Ruben

Announce: Pike Conference 2002
by Johan Sundström July 11, 2002

July 11, 2002

Call for Participation and Contributions Pike Conference 2002 - Aug 22-24 Pike and the Semantic Web RISE, the Research Center for Integrational Software Engineering, Linköping University (http://www.ida.liu.se/~rise/), has agreed to take over hosting, development, and maintenance of Pike, formerly at Roxen Internet Software AB. Pike is a second generation Java-like language, has a fast and reliable implementation, many killer applications, and a well running open source development community (http://pike.ida.liu.se/). Pike runs on most flavours of Unix, on the Win32 platform and MacOS X. Besides maintaining Pike a fast and reliable platform as it has been in the past, a main RISE goal is to make it the first scripting language for the Semantic Web. As a language, Pike is much better suited for the Semantic Web than Java or C#, since it provides multiple inheritance, sets, relations, and dynamic arrays. A second goal is to embed software composition technology into Pike. In the long run, Pike will be extended with modern concepts such as connectors or aspects. This way, Pike will strengthen the RISE center, whose mission is to develop practical composition and integration technology for software components. During August 22-24, 2002, RISE will host the next Pike User Group Meeting in Linköping (http://pike.ida.liu.se/conferences/2002/). RISE invites the Pike programmers all over the world to come to Linköping and hear more about these exciting perspectives. The meeting with the focus topic "Pike and the Semantic Web" will reveal more about the future strategy of Pike. - There will be workshops/discussions on various topics. - There will be an opportunity for people to present papers on relevant topics, give short presentations of projects etc. (Papers, abstracts and other material should be submitted in advance so we can schedule them properly. The tentative deadline is July 31 for such submissions.) - A small fee will be charged for participation, to cover the expenses for organising the conference. The fee has not yet been determined, but will be something like 20-30 Euro. Read more about it on http://pike.ida.liu.se/conferences/2002/. Welcome to Linköping!

RELEASED Mailman 2.0.12
by barry＠zope.com July 11, 2002

July 11, 2002

I've released version 2.0.12 of Mailman, the GNU Mailing List Manager. Mailman is released under the GNU General Public License (GPL). Version 2.0.12 fixes a cross-site scripting vulnerability among other changes. I recommend that folks upgrade their 2.0.x systems to this new version. See below for a NEWS file excerpt. GNU Mailman is software to help manage electronic mail discussion lists. Mailman gives each mailing list a unique web page and allows users to subscribe, unsubscribe, and change their account options over the web. Even the list manager can administer his or her list entirely via the web. Mailman has most of the features that people want in a mailing list management system, including built-in archiving, mail-to-news gateways, spam filters, bounce detection, digest delivery, and so on. Mailman is compatible with most web servers, web browsers, and mail servers. It runs on any Unix-like operating system. Mailman 2.0.11 requires Python 1.5.2 or newer. To install Mailman from source, you will need a C compiler. For more information on Mailman, including links to file downloads, please see any of the Mailman mirror web pages: http://www.gnu.org/software/mailman http://mailman.sourceforge.net http://www.list.org Patches and source tarballs are available at http://sourceforge.net/project/showfiles.php?group_id=103 There are email lists (managed by Mailman, of course!) for both Mailman users and developers. See the web sites above for details. Cheers, -Barry -------------------- snip snip -------------------- 2.0.12 (02-Jul-2002) - Implemented a guard against some reply loops and 'bot subscription attacks. Specifically, if a message to -request has a Precedence: bulk (or list, or junk) header, the command is ignored. Well-behaved 'bots should always include such a header. - Changes to the configure script so that you can pass in the mail host and web host by setting the environment variables MAILHOST and WWWHOST respectively. configure will also exit if it can't figure out these values (usually due to broken dns). - Closed another minor cross-site scripting vulnerability.

GadflyB5 1.0.0 - SQL Relational Database in Python
by Richard Jones July 10, 2002

July 10, 2002

================================================ Gadfly 1.0.0 - SQL Relational Database in Python ================================================ Gadfly is a relational database system implemented in Python based on the SQL Structured Query Language. This is the GadflyB5 release - like a NG release only better :) Note: Aaron Watters is not the contact for this project. The contact for this project is richard(a)users.sourceforge.net. Gadfly requires python 2.1 or later for correct operation. GadflyB5 is mostly the same old Gadfly, but: - updated to use new regular expression engine (regex -> re migration) performed by the fine folk at the Zope Corporation (http://www.zope.com/). - kjbuckets C extension module maintenance and updates (see the kjbuckets documentation for details) - documentation cleanup - cleanup and reorganisation of the gadfly modules, including: - migration to distutils-based installation - cleanup of SQL grammar marshalling - more strict (in places) unit/regression testing - general cleanup of the code itself - cleanup of networking code (note: gfclient argument list has changed!) Please read CHANGES.txt for a complete list of changes since the last release. There is no ongoing support available for usage, unless someone volunteers. If you have found a bug, please submit an issue to the bug tracker at: http://sourceforge.net/tracker/?atid=100662&group_id=662 If you've got a great idea for gadfly, and have the time to work on it, please contact the gadfly project admins.

Introducing pyNMS, SNMP, MIB and other tools for Python
by Keith Dart July 10, 2002

July 10, 2002

The pyNMS package is a collection of Python (and some C) modules for use in network management applications. It is also useful for testing and other types of applications. The package as a whole is currently in development, and much of the top-level NMS functionality (namely, a GUI interface). But, man low-level modules are still very useful for custom management scripts. Some notworthy sub-packages and modules: SNMP -- An implementation of SNMP v1 and v2c (Manager only now.. but Agent class just needs to be filled in). SMI -- A library, based on wrapping libsmi, for parsing and accessing MIB files. Devices -- Defines SNMP Manager objects for specific devices. You can create a class that represent as device, and define which MIBs it supports. POM -- Python Object Model for XML. This is patterned after XML DOM, but is more pythonic. It also incorporates some XPath funcionality. HTML -- Utilities and classes for creating XHTML documents. This is based on the POM module. This project is being hosted on Sourceforge. Home page: http://pynms.sourceforge.net/ Looking for feedback and testers. Have a Great day, Keith Dart

ANN: CherryPy-0.2 released
by remi＠cherrypy.org July 8, 2002

July 8, 2002

We're pleased to announce the release of CherryPy-0.2. This release fixes a minor bug that prevented non-Unix users from using the CookieAuthenticate module. ------------------------------------------ About CherryPy: CherryPy is a Python-based tool for developing dynamic websites. It uses many powerful concepts together, which makes it unique in its approach to website development. CherryPy sits between an application server and a compiler. You write source files, compile them with CherryPy and CherryPy generates an executable containing everything to run the website (including an HTTP server). CherryPy has been used in production for more than 6 months are we are now releasing it to the public, under the GPL license. Key properties/features of CherryPy are: - Based exclusively on Python (runs everywhere Python runs) - Delivers fast, robust, and scalable websites - Uses OOP as well as AOP (Aspect Oriented Programming) concepts to develop websites - True separation of content and presentation - Simple but powerful templating language - Powerful standard libraries to make your life easy Other properties/features are: - Can be linked to many databases (Oracle, Sybase, MySql, PostgreSql, ...) - Can run behind another webserver (Apache, ...) - Easy clustering and load-balancing set up for high-traffic websites Remi. http://www.cherrypy.org

ANN: Logging Module v0.4.6 released
by vinay_sajip＠yahoo.co.uk July 7, 2002

July 7, 2002

A new version of the proposed Python standard logging module (as per PEP 282) has been released. What Does It Do? ================ The logging module offers the ability for any Python program to log events which occur during program execution. It's typically used to provide application diagnostics, warnings and error messages. In addition to capturing "what happened", "where it happened", "when it happened", "how important it is" and event specific data, you can configure, without changing the application source code, both the verbosity of logging and the routing of events to different destinations such as console, disk files, sockets, email addresses, Web servers, SOAP servers etc. etc. You can even change the configuration of a running program without stopping and restarting it! You can use the logging module in exception handlers, and it will include traceback information in the log. It's thread-safe, and very easy to use - just "import logging" and log away! Classes provided include: Logger - used to log messages for a particular area of an application. You can instantiate these wherever you want, there's no need to pass references to them around your application. You can log events based on importance levels of DEBUG (least important), INFO, WARN, ERROR, and CRITICAL (most important). You can define your own levels if the default levels don't meet your requirements. Handler - used to route events to particular destinations. Handlers included are: StreamHandler (for generalized streams, including console) FileHandler (for disk files - including log file rotation with size limits for log files) SocketHandler (for sending events to a TCP socket) DatagramHandler (for sending events to a UDP socket - faster, but less reliable than TCP) SMTPHandler (send events to arbitrary email addresses) HTTPHandler (send events to Web servers) SysLogHandler (send events to Unix syslog) MemoryHandler (batch up events and process them several at a time) NTEventLogHandler (send events to Windows NT event logs) There are also examples of XMLHandler and SOAPHandler in the distribution. Formatter - used to format events as text strings. Flexible "msg % arg_tuple" formatting is the basis for formatting, with flexible date/time formatting including ISO8601 and any strftime-based formats. Filter - used when filtering based on importance (DEBUG/INFO/WARN/ERROR/CRITICAL) is not sufficient. The distribution includes examples of filters based on class matching, regular expression matching, value matching, and logger matching. In the unlikely event that you're daunted by all the apparent complexity, fear not. The module offers a simple function-based interface to allow very simple, almost casual use of the underlying features. In addition to the core logging functionality, you get the ability to configure logging using a ConfigParser-based text file format, a Tkinter-based GUI configurator which creates configuration files for you, and a simple network-based event receiver which receives events on TCP, UDP, HTTP and SOAP ports. This is suitable for testing and might perhaps serve as a model for your own event receivers. Also included are over 20 test scripts which serve both as test harnesses and examples of how to use the logging module. You can get more information from http://www.red-dove.com/python_logging.html There are "download" and "recent changes" links at the top of that page. The new stuff includes some bug fixes, better support for class-based filtering and logging, more documentation of the configuration file format, an example hand-coded configuration file for those people who can't use the GUI configurator, an example Filter for regular-expression match-based filtering, and more! As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last version: ================================= Added raiseExceptions to allow conditional propagation of exceptions which occur during handling. Added converter to Formatter to allow use of any function to convert time from seconds to a tuple. It still defaults to time.localtime but now you can also use time.gmtime. Added log_test22.py to test the conversion feature. Changed rootlogger default level to WARN - was DEBUG. Updated some docstrings. Moved import of threading to where thread is imported. If either is unavailable, threading support is off. Updated minor defects in python_logging.html. Check to see if ConfigParser has readfp method; if it does and an object with a 'read' method is passed in, assumes a file-like object and uses readfp to read it in.

spyce v1.1.22
by Rimon Barr July 7, 2002

July 7, 2002

Most important changes since last posting (v1.1.18) - easier install; .rpm should work on more systems - does not rely on mod_python by default... too hard to get right automatically, and users don't get to play with Spyce - downgraded some code to run on Python v2.1.1 and up. (requires nested scoping, so can't go further than that) - removed use of Python threads - new filter module - improved installation documentation, and explained how modules work ... and lots more. ---------- SPYCE - Server Python Pages SPYCE is a webserver plugin that supports simple and efficient Python-based dynamic HTML scripting. Those who like Python and are familiar with JSP, or PHP, or ASP, should have a look at this engine. It allows one to generate dynamic HTML content just as easily, using Python for the dynamic parts. Its modular design makes it very flexible and extensible. It supports FastCGI, CGI and mod_python to plugin into Apache and most other webservers. It can also be used as a command-line utility for HTML pre-processing. v1.1.22 released on 7 July 2002. Get it at: http://spyce.sourceforge.net ---------- Partial change log: v1.1.22 fixed Python v2.1.1-related bugs. improved installation process and documentation rpm more likely to succeed - uses fcgi or drops back to cgi no longer mod_python based by default v1.1.21 (faulty release) stochastic session clean up; no more threading dependency documentation: better installation notes peep-hole optimizer v1.1.20 (faulty release) created explicit (swappable) cache infrastructure BUG ** Spyce also works on Python v2.1 request - request.post(),post1() works in includes documentation: cheetah install, ... v1.1.19 filter module v1.1.18 fcgi support added X-Spyce header added documentation: how to write new modules v1.1.17 feature request - compaction algorithm improved ...

ANN: leo.py 2.5
by Edward K. Ream July 7, 2002

July 7, 2002

leo.py 2.5 is now available at: http://sourceforge.net/projects/leo/ The highlights of 2.5 --------------------- 1. Leo supports tab widths properly, and negative tab widths cause Leo to convert tabs to blanks as you type. Three new commands appear in the Edit Body menu: Convert Tabs, Convert All Tabs and Convert All Blanks. Convert All Tabs and Convert All Spaces convert the entire selected tree. 2. Leo now allows you to override selected preferences using a configuration file called leoConfig.txt. Leo acts as before if this file does not exist. An option in leoConfig.txt specifies whether leoConfig.txt is read-only. 3. The Preferences panel is now a modal dialog containing Ok, Cancel and Revert buttons. 4. At long last, cut and paste work properly in all situations. You can cut and paste between Leo and other applications, or between two different copies of Leo. 5. Added the Recent Files submenu to the File menu. 6. Fixed a number of bugs, including several crashers. Fixed several bugs in the Import commands. Leo will no longer abort reading if it detects an invalid directory name in the Default Tangle Directory in the Preferences panel. What is Leo? ------------ 1. A programmer's editor, an outlining editor and a flexible browser. 2. A literate programming tool, compatible with noweb and CWEB. 3. A data organizer and project manager. Leo provides multiple views projects within a single outline. 4. Fully scriptable using Python and saves its files in XML format. 5. Portable. leo.py is 100% pure Python and will run on any platform supporting Python and Tk/tcl. 6. Open Software, distributed under the Python License.

ANN: px/p4lib.py v0.6.6 - a p4 wrapper and a Python Perforce interface
by Trent Mick July 5, 2002

July 5, 2002

Where? http://starship.python.net/~tmick/ What are 'px' and 'p4lib.py'? Perforce is a source code control system (like CVS). One uses the p4 command line application (and/or a GUI client) to work with a Perforce repository. 'px' is a wrapper around p4. It provides all the functionality of p4 (defering work to it) plus it extends some standard p4 commands and adds a few new ones. If you are a Perforce user you might find these extensions useful. 'px' uses p4lib.py, a Python interface to the Perforce client application. If you are a Python programmer and script Perforce you might find this module helpful. Currently, most common commands (though your definition of "common" may differ from mine) are supported. What platforms? Windows and Linux. Cheers, Trent -- Trent Mick TrentM(a)ActiveState.com

ANN: 'which' v0.6.1 - A Python GNU-which replacement
by Trent Mick July 5, 2002

July 5, 2002

Where? http://starship.python.net/~tmick/ What is 'which'? GNU which is a common command line app on Unix. There are Windows ports (for example, the one in the Cygwin distribution), though I find the ones I have seen to be a little stupid. They don't understand the use of the PATHEXT environment variable. They don't support the useful '-a' option to listing all matches on the current PATH. This which has the following features: - it is portable (Windows, Linux); - it understands PATHEXT on Windows; - it can print all matches on the PATH; - it can note "near misses" on the PATH (e.g. files that match but may not, say, have execute permissions); and - it can be used as a Python module. What platforms? Windows and Linux. Cheers, Trent -- Trent Mick TrentM(a)ActiveState.com
