Zope BackTalk Working Session Invite
by Chris McDonough 20 Jun '01

20 Jun '01

(details also available via http://www.mindview.net/Seminars/BackTalkWorkingSession/) INTRODUCTION If you're a seasoned Zope, Python, or collaborative technology developer, you're invited to Crested Butte, Colorado between July 7 (Sat) - 10th (Tues) to help in a "working session" which has as a goal developing a 1.0 version of a "BackTalk" implementation for Zope. The working session is primarily a time for quickly iterating against an existing implementation, adding features and hardening as we go. If you come, you'll have an opportunity to meet other Zope and Python developers and have some fun hacking around on a neat project. This is *not* a seminar or teaching exercise, and thus is unstructured. We'll likely use some of the concepts from Extreme Programming (pairing, short iterations, etc), to keep us busy during the working session. Ideally, participants will have built Zope Products in the past. COST Free WHO WILL BE ATTENDING - Bruce Eckel (President, MindView, and author of Thinking In (Java|C++) and other books) - Chris McDonough (developer, Digital Creations) - You! WHAT IS BACKTALK "BackTalk" is an annotation and collaboration system devised by Bruce Eckel and Bill Venners. It is described at http://www.mindview.net/Books/BackTalk and http://www.mindview.net/Private/BackTalk . It is first and foremost a system which allows for inline commenting on prestructured content. It is close in sprit to systems such as Crit (http://www.crit.org) and Andamooka (http://www.andamooka.org) ** note: although the MindView documentation talks about BackTalk as nonfree software, it is describing the Java implementation. The Zope software produced as a result of the working session will be free ** BackTalk has two major design goals: - dramatically lower the bar for readers to provide inline comments on booklike content. - provide mechanisms for original document authors to fold contributions in the way of comments into the mainline document. IMPLEMENTATION GOALS Produce a Zope implementation of BackTalk which makes use of Zope-only features such as Structured Text (http://cmf.zope.org/doc/user/UsingStructuredText.txt/view) and the Zope object database [ZODB] (http://www.zope.org/Documentation/Articles/ZODB1) A prototype Zope implementation is (hopefully) accessible at http://serenade.4-am.com/BackTalkSandbox/ . If you have difficulty accessing the prototype, please let me know via email (it's a development box). IMPLEMENTATION HIT LIST (we might need you if you know anything about...) - BackTalk "back/forward" navigation system (DTML/Python) - BackTalk document end-of-document index generation (Python) - Table of contents generation (DTML/Python) - RTF-to-StructuredText converter (Python/C/whatever) - BackTalk-to-RTF converter (Python) - BackTalk-to-PDF converter (Python) - Javascript form elements (JavaScript) WHEN DOES THE SESSION START/END From: Saturday, July 7, 2001 To: Tuesday, July 10, 2001 session days begin at 9, end at 5. WHERE IS THE SESSION Crested Butte, Colorado (exact location in town to be announced) Directions and location details are available from http://www.mindview.net/Seminars/Locations/CrestedButte/CrestedButte.html HOW DO I SIGN UP Sign up via the registration system at http://www.mindview.net/Seminars/BackTalkWorkingSession. We have as a limit about 15 people. Hopefully, I'll see you there! - C

CMF 1.1 Released
by Tres Seaver 20 Jun '01

20 Jun '01

Digital Creations is pleased to announce the release of version 1.1 of its Content Management Framework (CMF). >From the README: What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. As packaged, the CMF generates a site much like the Zope.org site. The CMF is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Resources - The CMF "dogbowl" site, http://cmf.zope.org. - The mailing list, zope-cmf(a)zope.org. o List information and online signup are available at: http://lists.zope.org/mailman/listinfo/zope-cmf. o Archives of the list are at: http://lists.zope.org/pipermail/zope-cmf. Download - Get the "tarball", http://cmf.zope.org/download/CMF-1.1/CMF-1.1.tar.gz Installation - Please see "Installing CMF", http://cmf.zope.org/download/CMF-1.1/INSTALL.txt >From the Changelog: New features - Landed "skinned folder" module, which permits creation of "folderish" types with customized replacements for 'index_html'. - Added 'run_all_tests' script, to simplify running all unit tests for CMF-related products. - Factored out index and column lists, to ease customization (Tracker #289) - Modified 'DefaultDublinCoreImpl.setContributors' to use new tuplize functionality (the ability to pass in a different splitter function). If a string is passed in to setContributors(), it gets split on semicolons. This allows setting of contributor strings to be like "Doe, John E (john(a)doe.a.deer) The Mertz Family Foundation; PBS" If one so deeply and dearly desired. (The above would turn into a three element tuple). - Made it possible to map "normal" Zope objects as content (Tracker #283): o Skin and tool code which used to query the object for its Type in order to then ask the types tool for a TypeInfo object now just asks the types tool for type TypeInfo object directly. o Modified the TypesTool interface to signal that passing an object to 'getTypeInfo' is acceptable, with the semantic that the tool will attempt to find a TypeInfo object based on the tool's type or metatype. - Expanded signature of Document.CookedBody to change the header levels Structured Text starts rendering at, and whether to preserve those changes. Bug fixes - Hardened DirectoryView against objects which raise exceptions during initial reads (typically due to permission problems); these objects now capture and log the exception, and create a BadFile object which allows browsing the traceback via the ZMI (Tracker #317). - Stopped polluting the browser with persistent skin cookie; clear it as well on logout (Tracker #304). - Cleaned up folder content filtering (Tracker #298, thanks to Chris Withers for the patch). - Implement new "List folder contents" permission (Tracker #320), to prevent non-privileged users from being able to browse 'folder_contents' (permission is by default mapped to 'Owner' and 'Manager'). Note that this is really only a UI change: 'PortalFolder.contentIds', 'PortalFolder.contentValues', and 'PortalFolder.contentItems' are still public, to allow for reasonable "site map" views on folders. - Use saner type ID listing in 'search_form' (Tracker #324). - Rewired "POST target" skin methods, replacing filesystem-based DTML Methods with filesystem-based Python Scripts (from Tracker #301 -- thanks to Chris Withers). - Implemented *LARGE* patch to CMFDefault.DiscussionItem and CMFDefault.DiscussionTool, plus removal of CMFDefault.Discussions: changed threading strategy to remove dependency on the path of the "host" content object. Includes an ExternalMethod, CMFDefault/Extensions/update_discussion.py, which must be run to convert existing content which contains discussion. - Overrode DublinCore's isEffective in CMFCalendar.Event to always return true; this change prevents blocking view of the event by standard_html_header. - Updated INSTALL.txt to note that: o Use with Zope 2.4.0a1 is *not* recommended. o CMFDecor requires Zope Page Templates (Tracker #291). and to describe upgrade process from CMF 1.0. - Fixed typo in 'Unauthorized' exception raised by 'PortalContent._getDefaultView'. - Made all content types findable by catalog (Tracker #286). - Ensured that ContentTypeRegistry's "Test" tab doesn't puke if no MIMEtype is entered, or if one is entered which doesn't have a '/' in it (Tracker #292). - Suppressed overwrite of Subject when no 'Subject' or 'Keywords' headers were present (Tracker #294). - Ensured that 'Type' is indexed in newly-created 'portal_catalog'. - Fixed acquisition stripping in PortalContent.objectItems(). - Modified CMFDefault.DublinCore.getMetadataHeaders() to join Subject by commas, instead of spaces. Since we parse/split Subject on commas or semicolons now when a document is saved by FTP or WebDAV, we need to feed it out in the same format. - Fleshed out security declarations for 'portal_metadata' tool. - Corrected pathname of 'MemberDataTool.memberdataContents' to account for use of '_dtmldir' (thanks to Ricardo Newbery for the patch!). - Fixed buglet resulting from uninitialized local in 'PortalContent.objectItems' (thanks to Seb Bacon for the patch). - Modified stock 'search_form' to query 'Type' rather than 'meta_type'. - Removed debugging / "paranoia" print statements (thanks to Chris Withers for the patches). In the best traditions of open-source and free software, I am heading out of town tomorrow for a long vacation. Enjoy!

June 17th Zope Weekly News
by ethan mindlace fremen 17 Jun '01

17 Jun '01

Metadata, Developer's Guide update, new Zope.org progress, Lots of Page Template Proposals, and more in this week's news. The opinions expressed in Zope Weekly News are solely the authors', and not the opinions of Digital Creations, The Zope Community at-large, or the Spanish Inquisition. If you or your company are doing something cool with zope, "submit it to Zope Weekly News", mail:zope-web@zope.org for possible inclusion. ------ Upcoming Events EuroZope Conference The EuroZope crew is organizing a two day Zope only conference in Berlin on the 12th and 13th of July. Those interested in participating should join the discussion on the "EuroZope mailinglist", http://www.comlounge.net/mailman/listinfo/eurozope ------ Get Zope T-shirts! Ever have a hankering for a giant blue orb on your back? Well, now you can satisfy your craving. Score some "Zope Shirts":http://www.zope.org/Resources/Store and you'll be set. ------ Zope Developer's Guide by Michel Pelletier I'm happy to announce a new release of the Zope Developer's Guide, "available in HTML format", http://www.zope.org/Documentation/ZDG/ The new guide contains many improvements and elaborations over the previous HTML release, and has benefited from the review and contributions from many community members including well-known object-orienteers Jim Fulton, Guido van Rossum and Bruce Eckel. This will be the last "preview" release of the Dev guide before we release the first edition alongside the release of Zope 2.4. As usual, any problems suggestions should be noted in the "SourceForge tracker", http://sourceforge.net/projects/zope-devel/ ------ CMF News by Seb and Jon Traffic on zope-cmf was a little calmer this week, and the majority of it seemed to come from people noticing that the CMFDecor product doesn't work. Andrew "suggests":http://lists.zope.org/pipermail/zope-cmf/2001-June/007488.html removing the CMF Decor folder for now. In the mean time, don't worry - it's not an essential part of the CMF. Workgroups It's not always clear how to apply Zope's Security machinery to 'workgroup' scenarios. Jens "posted":http://lists.zope.org/pipermail/zope-cmf/2001-June/007537.html his ideas for implementing Workgroups in CMF. Shane "showed":http://lists.zope.org/pipermail/zope-cmf/2001-June/007578.html how you might accomplish a similar thing using his cutting-edge DCWorkflow. The discussion continued in a slightly different direction following "Scott's post":http://lists.zope.org/pipermail/zope-cmf/2001-June/007577.html on subjects/metadata. Will CMF become the "weapon of choice" for intranet managers? Metadata - The Next Generation The use and application of Dublin Core Metadata has come under scrutiny this week. Tim Lynch "posted":http://lists.zope.org/pipermail/zope-cmf/2001-June/007434.html some useful background information on the uses of Dublin Core in the "World Outside CMF" (tm) - to which Tres "responded":http://lists.zope.org/pipermail/zope-cmf/2001-June/007448.html with more details of DC's perspective on the DC. Subclassing the DublinCore each time you want to extend it can be a bit of a pain. Shane "proposes":http://lists.zope.org/pipermail/zope-cmf/2001-June/007570.html a new implementation; Tres turns fashion-guru and introduces "aspect bags":http://lists.zope.org/pipermail/zope-cmf/2001-June/007587.html - every well dressed content-object will be carrying one this summer. "Aspect oriented programming":http://www.parc.xerox.com/csl/projects/aop/? Lesser mortals reach for their "dictionaries":http://citeseer.nj.nec.com/highley99aspect.html! Bite-Sized Chunks Seb released a "first cut":http://lists.zope.org/pipermail/zope-cmf/2001-June/007608.html of his Mailin Product. We're one step closer to updating from the beach! Chris W leaked the news that Swishdot will incorporate this functionality, giving a mailinglist/weblog cross - genetic-engineering at its best! Some useful "tips":http://lists.zope.org/pipermail/zope-cmf/2001-June/007474.html from Jeff on how to get CMFWiki working from CVS... and Tres "clarifies":http://lists.zope.org/pipermail/zope-cmf/2001-June/007501.html DC's thinking on the future of this product. In short, you can use it, but it's not 'supported' officially. "Zopefish":http://zopefish.weblogs.com/2001/06/08 dives into CMF. Onlookers drool at the prospect of Zopefish/CMF integration! Has anyone told "Dave Winer":http://www.scripting.com? Marc's Colour-Guide undergoes "cosmetic surgery":http://cmf.zope.org/Members/grifter70000/color_guide, courtesy of Dr Grifter. Are you thinking of running several CMFs in the same Zope instance? Want to share common skins? So does "Chris W":http://lists.zope.org/pipermail/zope-cmf/2001-June/007500.html - Shane "suggests":http://lists.zope.org/pipermail/zope-cmf/2001-June/007509.html filesystem-based skins The "CMF Dogbowl Calendar":http://cmf.zope.org/calendar/calendar is up and running. One to watch for forthcoming Zope-related events. Silly Stats (last week's figures in brackets):: 159 messages (350) 42 people posted (50) 55% were by 12% of people (70%:40%) 8 bugs were resolved (?) 3 were submitted (?) ------ Page Templates Page Templates are already quite useful, but there's been a lot of activity lately on "proposed changes", http://www.zope.org/Wikis/DevSite/Projects/ZPT/ProposedChanges including * Replace Inner Text -- editors tend to be a touch indiscriminant about how they mark up code: your attribute markup can have font tags and other markup inserted inside it. What should happen then? * Variable Expansion in Paths -- it would be nice if the path could include components that are actually variables. * Disappearing tags -- it would be nice if some marked up tags went away after they are done doing their dynamic thing. A new tal attribute and a block tag have been proposed as solutions. * Search And Replace -- somewhat related to the prior issue, having some way of specifying placeholders that indicate items to be replaced in non-marked up text (think JavaScript) would be nice. * Commenting -- A tal:comment directive? There's more! Go to the page templates project and join in the discussion. ------ Zope Web by Ethan Fremen "Zope.org enhancement", http://dev.zope.org/Wikis/DevSite/Projects/ZopeOrgCollaborationEnhancement Skin Madness ...Page Templates are a lot of fun. At the end of this project you'll be able to view_source on the zope.org site and get loads of good ZPT examples! The "workflow", http://dev.zope.org/Wikis/DevSite/Projects/ZopeOrgCollaborationEnhancement/ WorkFlow has received a lot of work, thanks to Jens Vagelpohl. Work on a redirector to support the migration machinery is also near completion, thanks to Andreas Jung. -EOT-

Calling and returning objects
by Eric Vautour 15 Jun '01

15 Jun '01

Hello all, I have a question that may or may not be answerable. I have a site that is set up as so: There is a something.htm that calles other objects, like so: <dtml-var level1_header> <dtml-var level1_sidebar> <dtml-var l1_phoneit> <dtml-var l1_dialit> <dtml-var l1_findit> <dtml-var level1_footer> I was wondering if there was a way that I could extract the information from this ".htm" object so that I could determine which objects are being called from it, excluding the header, footer, and sidebar. Is this possable? Thanks
