by stani_＠hotmail.com Sept. 10, 2003

Sept. 10, 2003

Spe 0.1.6 --------- Spe is a python IDE with auto-indentation, auto completion, call tips, syntax coloring, syntax highlighting, class explorer, source index, auto todo list, sticky notes, integrated pycrust shell, python file browser, recent file browser, drag&drop, context help, ... Special is its blender support with a blender 3d object browser and its ability to run interactively inside blender. Spe is extensible with boa. This release normally should have been on the blender_ website. Unfortunately this is not possible. Therefore the latest release will be available from the link *Download latest release* under the calendar of http://spe.pycs.net The focus in the spe development for the recent time has been to make it as stable as possible for Linux. This release should run without (major) problems outside blender_ in Linux (see also *External bugs*). Following information is relative to 0.1.5.c: :Links: - Homepage: http://spe.pycs.net - Website: http://projects.blender.org/projects/spe/ - Screenshots: http://spe.pycs.net/pictures/index.html - Forum: http://projects.blender.org/forum/?group_id=30 - RSS feed: http://spe.pycs.net/weblog/rss.xml :New features: - linux wrapper script to launch spe from the console - spe updated for python_ 2.3 - spe help manual (Help menu>Manual) - help window resizable - blender_ python_ API documentation added to help menu - homepage: http://spe.pycs.net (thanks to pyds_ and pycs_) - webbrowser used for displaying bigger help files in blenpy and spe - keyboard shortcuts in separate configurable python file :Requirements: - full python_ 2.2 or 2.3 - wxpython_ 2.4.1.2 - optional blender_ 2.28a (updated!) :Known Issues: - Keyboard copy&paste operations in shell are stolen by editor. :External bugs: - the Linux blender_ binaries of blender_.org are unfortunately not compatible with spe. blender_ still uses an old version of the libpng (1.0.x), while spe requires a newer version. Therefore compile blender_ from the sources with libpng 1.2.x to make spe running in blender_. This problem doesn't apply to Windows users, as the windows blender_ binary ships strangely enough already with the new version of libpng. - View end of line marker fails (probably wxpython_ bug) :Fixes: - class browser fixed - usermenu problem - spe can now close without open documents - sidebar updates automatically when it gets focus - enter now doesn't generate extra spaces with auto-complete - blender_ 2.28a no longer crashes by exploring the Text window - no pycrust_ warnings anymore - todo tab: line scrolling - about.htm is included (was missing) - add your own menu help dialog typo - shortcuts dialog typo - busy cursor fix - recent files does not display longer not existing files - separators added between toolbar buttons - ...and some more 3 minor fixes - explore tab: text height (Linux) - font size text dialogs (Linux) - 11 fixes for visibility problems (mainly Linux) - README.txt with better instructions for Linux users. :Contributors: - Tina Hirsch (Linux bug fixing) - Andrei (feedback) http://project5.tk :Wanted: - MacOs X tester for MacOs X screenshot - wxpython_ programmers

ANN: HeyHeyWickie 0.1 - an experimental WikiWiki platform (plus online article)
by Dinu Gherman Sept. 9, 2003

Sept. 9, 2003

Hi, I'm glad the folks at Linux-Magazine.com have put an article of mine (appearing in the october 2003 issue) on their site for people to download. It's about an experimental WikiWiki system of mine called HeyHeyWickie which uses EmPy and Docutils. The article describes neither of these two in great detail, but shows what you can do with them. It's available on my publications page or directly at the ma- gazine's: http://python.net/~gherman/Presentations.html http://www.linux-magazine.com/issue/35/EmPy_Wiki.pdf The pretty minimal version of HeyHeyWickie itself (only 4 KB) is available here: http://python.net/~gherman/HeyHeyWickie.html I'm working on a more advanced version which will also be available, soon, and which I'm using to create my pages on the Starship Python: http://python.net/~gherman Gruss, Dinu -- Dinu C.

ANN: ReSTedit 0.2 - an OS X GUI for interactively exploring ReStructuredText
by Dinu Gherman Sept. 9, 2003

Sept. 9, 2003

Hi, the last one for today is "ReSTedit", a native Mac OS X Cocoa GUI tool using PyObjC and Docutils to provide an intuitive way of exploring, editing and rendering text in the ReStructuredText format. Please see the attached Readme below. As usual I'm grate- ful for any comments or insights you might have to share! Regards, Dinu -- Dinu C. Gherman ...................................................................... "There comes a point when we the people must demand more of our elected officials than just showing up." (Arnold Schwarzenegger) ReSTedit ========= Summary ------- ReSTedit is a Mac OS X demo for interactively exploring ReStructuredText. Overview -------- ReSTedit is a GUI tool for editing and interactivly exploring texts in the ReStructuredText [1]_ format (or ReST) as introduced by the Docutils [2]_ project. Despite being very simple ReSTedit is very useful for quickly checking if Docutils renders some text as you would expect it. You only paste it into a ReSTedit window to see if it's ok or not, without writing any test code around it. Basics ------ ReSTedit is extremely simple to use. You paste an input text into the lower half of a window or type it in there and ReSTedit renders your text into the default HTML format which it displays in the upper half of the window. The rendering takes place silently in the background and the upper output half will tell you which errors were detected if there were any. And that's it. When you're done you can copy your text out, again... Hyperlinks are displayed the usual way and are clickable, too (launching your default webbrowser). And images are also correctly displayed (don't forget the file:// prefix for local files!). History ------- :0.1: first release, relying on an external Python interpreter :0.2: repackaged with Python 2.2.3 and PyObjC 1.0b and Docutils 0.3 included Requirements ------------ There are no special requirements for running ReSTedit. From version 0.2 it ships as a standalone application which should be running on any Mac OS X 10.x, althouth it was developped on 10.2. As it comes with full source code you can build ReSTedit yourself, if you have Apple's developer tools installed, plus some Python interpreter version 2.2 or higher, plus PyObjC 1.0b [3]_. Licence ------- ReSTedit is released under the GPL - see the included file, "GPL.txt". Download -------- The ReSTedit distribution, screenshots and a sample movie of ReSTedit in action are all available from: http://python.net/~gherman/ReSTedit.html Notes ------ Among other GUI tools similar to ReSTedit is DocFactory [4]_. If you know more of them, please send me a short note. Future ------ ReSTedit is really just a proof of concept. I'm certainly not planning to make it a full-fledged editor. Right now, ReSTedit does nothing meaningful when attempting to save or open a file, but this will be enabled, soon. As usual: your help and suggestions are very welcome! Links ----- ..

ANN: RegexPlor 0.6 - an OS X GUI for interactively exploring regular expressions
by Dinu Gherman Sept. 9, 2003

Sept. 9, 2003

Hi, Next in line is "RegexPlor", a native Mac OS X Cocoa GUI tool using PyObjC to provide an intuitive way of exploring regular expressions. Please see the attached Readme below. I'd be grateful for any comments you might have! Regards, Dinu -- Dinu C. Gherman ...................................................................... "I am a gentlemen: I live by robbing the poor." (George Bernard Shaw) RegexPlor ========= Summary ------- RegexPlor is a Mac OS X tool for interactively exploring regular expressions. Overview -------- RegexPlor is a tool for interactively exploring regular expressions. It provides a graphic frontend for experimenting with such regular expressions in a intuitive way. You can edit an input text as well as a regular expression as well as colors for matched text, etc. and study various effects at every keystroke. This is a much more convenient way of hunting down the one expression you're after, without typing any code at all in the usual trial-and-error method. Basics ------ RegexPlor is pretty intuitive to use. There are three differen panes or views you can switch between at the top of the window. The input pane shows the input text and the regular expression to be applied to it. Change any of them and various ways of matching (selectable using the bottom buttons) will be applied instantly, resulting in coloring the respective portions of the input text. Colors and specific matching options can be changed in the drawer popping out horizontally of the main window. The output pane is divided into several columns where the respective text portions can be easily copied from if you need them somewhere else. Here you can also replace text using the drawer popping out vertically of the main window when the Replace button is pressed. The Syntax pane provides a summary about the regular expression syntax which you can look-up to use special features. The files in samples/ only provide a starting point for your own exploration of regular expressions. History ------- :0.5: first release, relying on an external Python interpreter :0.6: repackaged with Python 2.2.3 and PyObjC 1.0b included, minor fixes Requirements ------------ There are no special requirements for running RegexPlor. From version 0.6 it ships as a standalone application which should be running on any Mac OS X 10.x, althouth it was developped on 10.2. As it comes with full source code you can build RegexPlor yourself, if you have Apple's developer tools installed, plus some Python interpreter version 2.2 or higher, plus PyObjC 1.0b [1]_. Licence ------- RegexPlor is released under the GPL - see the included file, "GPL.txt". Download -------- The RegexPlor distribution, screenshots and a sample movie of RegexPlor in action are all available from: http://python.net/~gherman/RegexPlor.html Notes ------ Among the undoubtly many other GUI tools similar to RegexPlor are Kodos [2]_ and Regex-Coach [3]_. If you know more of them, please send me a short note. You might experience some strange effects with RegexPlor when moving the window accross the screen. I suspect this is somehow related to the metal texture being used, but I'm not sure yet. It usually disappears quickly after clicking in some places of the windows. If you happen to know the reason for that please tell me. At the moment, RegexPlor does nothing meaningful when attempting to save or open a file. This will probably be disabled, soon. Future ------ I think RegexPlor 0.6 is quite complete in terms of functionality but I'd like to mark text also using background colours like it is done in Hydra, but I have no idea how that can be done. Again, if you know... And then the usual localization etc. Your help and suggestions are very welcome! Links ----- .. [1] http://pyobjc.sourceforge.net .. [2] http://kodos.sourceforge.net ..

ANN: Pycotine 0.4 - an OS X GUI to the PyUnit test framework
by Dinu Gherman Sept. 9, 2003

Sept. 9, 2003

Hi, after becoming a happy bundlebuilder user I'm about to repackage a few tools and proto-tools of mine to increase their usability for a wider audience. Number one is "Pycotine" a native Mac OS X Cocoa GUI using PyObjC to the PyUnit test framework. Please see the attached Readme below. I'm glad about any comments you might have! Regards, Dinu -- Dinu C. Gherman ...................................................................... "Fascism should more appropriately be called corporatism because it is a merger of state and corporate power." (Benito Mussolini) Pycotine ======== Summary ------- Pycotine is a Mac OS X Cocoa GUI to the PyUnit test framework. Overview -------- Pycotine (Python Cocoa Test Interface Environment) is a Cocoa GUI for Mac OS X to Steve Purcell's PyUnit test framework [1]_. It allows you to execute a Python testsuite, possibly spread over many modules, comfortably from an application which shows statistical information about the ongoing tests with various counters and a progress bar. Errors and failures, usually reported on the commandline, are listed in a seperate part of the window. The user interface is very much designed after an existing Tkinter version [2]_. Basics ------ Using Pycotine you can open Python files (with extension ".py") and execute testsuites created in these files with the "unittest" module of the Python 2.x standard library. Right now, Pycotine first trys to import a function named "suite()" or "makeSuite()" from an opened Python module which it assumes to build and return a testsuite. If no such functions are found, it will search for all subclasses of unittest.TestCase in the top-level of the selected Python module. The test files in samples/ were shamelessly copied from Steve Purcell's own original test cases for PyUnit 1.4.1 (just skipping the Tkinter ones for obvious reasons). I added only one new file, "listtestsfail.py" which shows a test failing on purpose, too. There is one known bug which can crash Pycotine when it tries to load files having a full path with blanks and/or non-ASCII characters. History ------- :0.2: first release, written in Objective-C, relying on an external Python interpreter :0.3: fully reimplemented in Python, using PyObjC :0.4: repackaged with Python 2.2.3 and PyObjC 1.0b included Requirements ------------ There are no special requirements for running Pycotine. From version 0.4 it ships as a standalone application which should be running on any Mac OS X 10.x, althouth it was developped on 10.2. As it comes with full source code you can build Pycotine yourself, if you have Apple's developer tools installed, plus some Python interpreter version 2.2 or higher, plus PyObjC 1.0b. Licence ------- Pycotine is released under the GPL - see the included file, "GPL.txt". Download -------- The Pycotine distribution, screenshots and a sample movie of Pycotine in action are all available from: http://python.net/~gherman/Pycotine.html Notes ------ Pycotine was developped from its author's personal frustration with running (or rather not running) Tkinter on Mac OS X as the only existing GUI for PyUnit. While at the time it might have well been possible to get Tkinter running, it was probably easier to write this little tool... Originally, Pycotine was written as a vanilla Cocoa application (sic!) in Objective-C, calling a dedicated TestRunner class in Python. Today, Pycotine is written entirely in Python using the excellent PyObjC [3]_ bridging technology. Future ------ The future is uncertain, but I might spend a bit more time on this tool to add localisation to a few more languages and or make the errors and failures output more useful. Your help and suggestions are very welcome! Links ----- .. [1] http://pyunit.sourceforge.net/ .. [2] http://pyunit.sourceforge.net/screenshot.gif ..

ANN: EmPy 3.1 -- A powerful templating system for Python
by Erik Max Francis Sept. 9, 2003

Sept. 9, 2003

Summary A powerful and robust templating system for Python. Overview EmPy is a system for embedding Python expressions and statements in template text; it takes an EmPy source file, processes it, and produces output. This is accomplished via expansions, which are special signals to the EmPy system and are set off by a special prefix (by default the at sign, '@'). EmPy can expand arbitrary Python expressions and statements in this way, as well as a variety of special forms. Textual data not explicitly delimited in this way is sent unaffected to the output, allowing Python to be used in effect as a markup language. Also supported are callbacks via hooks, recording and playback via diversions, and dynamic, chainable filters. The system is highly configurable via command line options and embedded commands. Expressions are embedded in text with the '@(...)' notation; variations include conditional expressions with '@(...?...!...)' and the ability to handle thrown exceptions with '@(...$...)'. As a shortcut, simple variables and expressions can be abbreviated as '@variable', '@object.attribute', '@function(arguments)', '@sequence[index]', and combinations. Full-fledged statements are embedded with '@{...}'. Control flow in terms of conditional or repeated expansion is available with '@[...]'. A '@' followed by a whitespace character (including a newline) expands to nothing, allowing string concatenations and line continuations. Comments are indicated with '@#' and consume the rest of the line, up to and including the trailing newline. '@%' indicate "significators," which are special forms of variable assignment intended to specify per-file identification information in a format which is easy to parse externally. Context name and line number changes can be done with '@?' and '@!' respectively. Escape sequences analogous to those in C can be specified with '@\...', and finally a '@@' sequence expands to a single literal at sign. Getting the software The current version of empy is 3.1. The latest version of the software is available in a tarball here: http://www.alcyone.com/software/empy/empy-latest.tar.gz. The official URL for this Web site is http://www.alcyone.com/software/empy/. Requirements EmPy should work with any version of Python from 1.5.2 onward. It has been tested with all major versions of CPython from 1.5 up, and Jython from 2.0 up (using Java runtimes 1.3 and 1.4). The included test script is intended to run on Unix-like systems with a Bourne shell. License This code is released under the GPL. .... Release history [since 3.0.4] - 3.1; 2003 Aug 8. Unicode support (Python 2.0 and above); added Document and Processor helper classes for processing significators; added --no-prefix option for suppressing all markups. -- Erik Max Francis && max(a)alcyone.com && http://www.alcyone.com/max/ __ San Jose, CA, USA && 37 20 N 121 53 W && &tSftDotIotE / \ War is a continuation of policy by other means. \__/ Karl von Clausewitz

PyPy "Berlin" sprint (29th Sep - 4th Oct 2003)
by holger krekel Sept. 7, 2003

Sept. 7, 2003

hello python developers, the fourth PyPy coding sprint will take place in Berlin (Germany) from (morning of) 29th of September to (evening of) 4th of October 2003. All Python developers are welcome to join the sprint. See below for participation details. What is PyPy? ------------- PyPy is a remimplementation of Python in the Python language itself. Simplicity and flexibilty are the foremost goals. With PyPy we want it to be easy to extend the language or generate a more minimal language implementation. One key technique to making this feasible is to specialize our abstract/general PyPy-Python implementation into native code (e.g. C-code). Eventually the concepts of PSYCO and Stackless are to be integrated into PyPy. There is, of course, much more to it so feel free to consult some documents especially our Oscon-2003 paper on this page: http://codespeak.net/pypy/index.cgi?doc We know that many areas and issues are still somewhat vague although PyPy can already run many python programs [*]. Fortunately, Python is pretty tolerant about expressing ideas in vague ways. After all, hacking at PyPy aims (and already proved!) to preserve the fun of hacking in Python. History, status and Berlin goals -------------------------------- The project started in Jan/Feb 2003 with an initiative from Christian Tismer, Holger Krekel and Armin Rigo. During the course many more developers joined our sprints and there are now between 5 and 15 people involved in developing PyPy. The three sprints resulted in a fully working interpreter, some development infrastructure and the "standard object space" which is an abstraction for operations on standard (CPython) objects. There is no public release yet, you more or less have to install a subversion-client and checkout the trunk. Here is our 'howtosvn' which contains up-to-date clients for multiple platforms along with some instructions how to get started: http://codespeak.net/pypy/index.cgi?doc/devel/howtosvn.html Main goals for the Berlin sprint are - integration/enhancement of a Python parser and the compiler package - generating native code from our Python interpreter/types implementations - enhancing/correcting/completing what we have (various tasks) How to participate in Berlin (29th of Sept. to 4th of October) -------------------------------------------------------------- If you are interested to participate please subscribe at our sprint organization list http://codespeak.net/mailman/pypy-sprint and please list yourself at http://codespeak.net/moin/pypy/moin.cgi/SprintAttendants so that we can organize accomodation and arrange details. Costs should be pretty low (except from travelling costs, of course). Currently nine people are scheduled to come. Btw, the sprint starts early on the 29th of september so it's best to arrive on sunday, 28th. Also we probably want to have one day off during the sprint week to do some sight (or cafe+pub) seeing. Actually it's much better to participate the whole week to better get into it. cheers, holger [*] and currently only 20-40 thousand times slower than CPython! which clearly shows that we are successfully follow the "premature optimization is the root of all evil" maxime.

PyRSS2Gen-0.0 - an RSS 2.0 generator for Python
by Andrew Dalke Sept. 7, 2003

Sept. 7, 2003

PyRSS2Gen - an RSS 2.0 generator for Python http://www.dalkescientific.com/Python/PyRSS2Gen.html I've finally decided to catch up with 1999 and play around a bit with RSS. I looked around, and while there are many ways to read RSS there are remarkably few which write them. I could use a DOM or other construct, but I want the code to feel like Python. There are more Pythonic APIs I might use, like the effbot's ElementTree, but I also wanted integers, dates, and lists to be real integers, dates, and lists. The RSS generators I found were built around print statements. Workable, but they almost invariably left out proper HTML escaping the sort which leads to Mark Pilgrim's to write feed_parser, to make sense of documents which are neither XML nor HTML. Annoying, but sadly all too common. Those which were more correct (like RSS.py) didn't support all the options in an RSS feed. This version uses native Python classes, with (untested) support for developing your own RSS extensions. It generates the output using the standard SAX2 content handlers, so everything must be appropriately escaped. And it like Python data types, including datetime. Here's what it looks like: import datetime import PyRSS2Gen rss = PyRSS2Gen.RSS2( title = "Andrew's PyRSS2Gen feed", link = "http://www.dalkescientific.com/Python/PyRSS2Gen.html", description = "The latest news about PyRSS2Gen, a " "Python library for generating RSS2 feeds", lastBuildDate = datetime.datetime.now(), items = [ PyRSS2Gen.RSSItem( title = "PyRSS2Gen-0.0 released", link = "http://www.dalkescientific.com/news/030906-PyRSS2Gen.html", description = "Dalke Scientific today announced PyRSS2Gen-0.0, " "a library for generating RSS feeds for Python. ", guid = PyRSS2Gen.Guid("http://www.dalkescientific.com/news/" "030906-PyRSS2Gen.html"), pubDate = datetime.datetime(2003, 9, 6, 21, 31)), PyRSS2Gen.RSSItem( title = "Thoughts on RSS feeds for bioinformatics", link = "http://www.dalkescientific.com/writings/diary/" "archive/2003/09/06/RSS.html", description = "One of the reasons I wrote PyRSS2Gen was to " "experiment with RSS for data collection in " "bioinformatics. Last year I came across...", guid = PyRSS2Gen.Guid("http://www.dalkescientific.com/writings/" "diary/archive/2003/09/06/RSS.html"), pubDate = datetime.datetime(2003, 9, 6, 21, 49)), ]) rss.write_xml(open("pyrss2gen.xml", "w")) And amazingly enough, it actually validated on the first try!
