Invitation to PyCon
by Steve Holden 23 Mar '03

23 Mar '03

Well, looks like it's PyCon weekend in DC, folks, and here we are amid the cherry blossom (sadly not a feature of this year's cherry blossom festival). The registrations have been smoothly handled by our colleagues of Yet Another Society, for which we thank them. Those who have had to request a refund should expect a formal response shortly before or after PyCon ends. If you do not receive such a response by email, please contact me to ensure your details have been received. I look forward to putting faces to many names, and extend the hand of friendship to all pythonistas, whether attending PyCon or not. There's a goodly crowd attending, barring any travel-related problems such as weather (which featured in my missing the first Python conference I booked). The sprinters are already converging to begin work on Monday, and if you aren't sprinting then think about coming in on TUESDAY AFTERNOON to register early and avoid the morning rush on Wednesday. PyCon's organizers are all interested in hearing your feedback on the conference, and this will be the theme of a session late in the agenda, where your feedback (negative and, hopefully, ;positive)can be made more publicly. Over all we are trying to provide an interesting week with access to Python talent, humor, conceit, and all else that we consider positive about the language. If you aren't already registered then it will cost you $250 at the door (again, if you want to register AT THE CONFERENCE we recommend that you register ON SITE TUESDAY AFTERNOON with your credit card). There has apparently been a good response to our call for gophers, and I'd like to thank all our volunteer gophers in advance for helping to keep the wheels rolling. Ladies and gentlemen, welcome to PyCon DC 2003 week -- Steve Holden http://www.holdenweb.com/ Python Web Programming http://pydish.holdenweb.com/pwp/ Register for PyCon Tuesday March 25 at GWU's Cafritz Conference Center

RELEASE: ClientForm 0.0.7
by John J Lee 23 Mar '03

23 Mar '03

http://wwwsearch.sourceforge.net/ClientForm/ Changes since 0.0.5: * Empty TEXTAREA case fixed. * Exception is no longer raised for INPUT TYPE=FILE -- instead, FILE controls are just ignored (they will be handled properly in 0.1.x). * Documentation improvements to web page (note that the web page is more up to date than the copy of same in the package -- sorry). Requires Python >= 1.5.2. ClientForm is a Python module for handling HTML forms on the client side, useful for parsing HTML forms, filling them in and returning the completed forms to the server. It has developed from a port of Gisle Aas' Perl module HTML::Form, from the libwww-perl library, but the interface is not the same. Simple example: from urllib2 import urlopen from ClientForm import ParseResponse forms = ParseResponse(urlopen("http://www.acme.com/form.html")) first_form = forms[0] form["author"] = "Gisle Aas" # form.click returns a urllib2.Request object # (use the items argument to this method if you're not using urllib2) response = urlopen(form.click("Thanks")) John

RELEASED email package version 2.5
by Barry Warsaw 21 Mar '03

21 Mar '03

I've just released the (standalone) email package version 2.5. This is identical to the version that is in the current cvs development tree for Python 2.3. I've also backported it to what will be Python 2.2.3. email 2.5 is made available as a distutils package for installing in earlier versions of Python. It is compatible with Python 2.1 Python 2.2, and Python 2.3. See below for a summary of changes. The email package is a library for parsing, handling, and generating email messages and other RFC 2822 style documents. It conforms to most of the email related RFCs including 2045-2047 (the MIME RFCs) and 2231. It is intended to replace several older modules in the standard distribution, such as rfc822, mimetools, multifile, mimify, and MIMEWriter, and such non-standard modules as mimecntl. email-2.5.tar.gz is available from the mimelib project on SourceForge: http://sf.net/projects/mimelib More information, as well as on-line documentation is available on the home page: http://mimelib.sf.net Enjoy, -Barry -----snip snip----- - Message.get_payload() now recognizes various uuencoded Content-Transfer-Encodings (e.g. x-uuencode). When passing decode=True to Message.get_payload() and a low-level decoding error occurs, the payload is returned as-is instead of raising an exception. - Header.__init__() and Header.append() now accept an optional argument `errors' which is passed through to the unicode() and ustr.encode() calls. You can use this to prevent conversion errors by e.g. passing 'replace' or 'ignore'. RFC 2822 specifies that long headers should be split at the "highest level syntactic break" possible. This can only really be determined by the application, and the current API doesn't support arbitrary break points. As a compromise, Header.encode() grew a `splitchars' argument which provides some control over splitting at higher level syntactic breaks. Header.decode_header() now transforms binascii.Errors into email.Errors.HeaderParseErrors when bogus base64 data appears in the header. The header splitting and folding algorithms were completely reimplemented, especially when dealing with ASCII headers. We now preserve spaces between encoded and non-encode parts in RFC 2047 headers when converting the header to Unicode. While the RFC is technically ambiguous on this point, this is the behavior most people expect. - email.Iterators.body_line_iterator() now takes an optional decode argument, which is passed through to Message.get_payload(). - The MIMEText constructor used to append a newline to the _text argument if it didn't already end in a newline. Now it doesn't. - The quopriMIME.header_encode() maxlinelen argument now accepts None, which inhibits line breaking. - Support for Korean charsets was added to Charset.py. Also the Charset class grew a __repr__() method. - Various and sundry bug fixes, improved RFC conformance, and improved lax parsing.

ANN: Java-to-Jython Browser
by Paul M 20 Mar '03

20 Mar '03

Description ------------ I've created a little app for browsing Java classes and querying their events, bean properties, and methods as seen from Jython. It's based on some example code from Richard Hightower's book "Python Programming with the Java Class Libraries" combined with a GUI that makes it easy to use. Since I'm inexperienced with the Swing API, I've found this to be a particularly useful tool for learning how to build Swing-based GUIs from Jython. Download -------- http://kim.bio.upenn.edu/~pmagwene/java2jython.html Contact ------- Feedback, recommendations, and constructive critique are appreciated. Send email comments to p.magwene(a)snet.net Cheers, Paul
