Although it might be something obvious but I cannot think of it at the moment. How do I delete attributes created with the "attribute" method?

test driven development
by Victor Mayevski 18 May '11

18 May '11

I am beginning to learn and use test driven development in my projects. I've noticed that NX does not use the standard "tcltest" package in Tcl but instead provides it's own "nx::test". Is there a specific reason for that? Thanks, Victor

The following (incorrect) usage will cause a crash: ***** % o attribute {a v} ::o::a % o::a #Incorrect usage Segmentation fault ***** The next one, however, does not crash: ***** % Object create o ::o % o attribute {a v} ::o::a % o a # Correct usage first v % o::a # Incorrect usage can't read "o::a": no such variable while executing "o::a" % *****

18th Annual Tcl/Tk Conference (Tcl'2011) http://www.tcl.tk/community/tcl2011/ October 24 - 28, 2011 Comfort Suites Manassas Manassas, Virgina, USA Important Dates: Abstracts and proposals due August 26, 2011 Notification to authors September 12, 2011 WIP and BOF reservations open August 1, 2011 Author materials due October 9, 2011 Tutorials Start October 24, 2011 Conference starts October 26, 2011 Email Contact: tclconference(a)googlegroups.com Submission of Summaries Tcl/Tk 2011 will be held in Manassas, Virgina, USA from October 24 - 28, 2011. The program committee is asking for papers and presentation proposals from anyone using or developing with Tcl/Tk (and extensions). Past conferences have seen submissions covering a wide variety of topics including: * Scientific and engineering applications * Industrial controls * Distributed applications and Network Managment * Object oriented extensions to Tcl/Tk * New widgets for Tk * Simulation and application steering with Tcl/Tk * Tcl/Tk-centric operating environments * Tcl/Tk on small and embedded devices * Medical applications and visualization * Use of different programming paradigms in Tcl/Tk and proposals for new directions. * New areas of exploration for the Tcl/Tk language This year is the fourth year that the Tcl community is participating in the Google Summer of Code. The conference program committee would like to encourage submissions that report on the Tcl projects selected for Google SoC 2011. Submissions should consist of an abstract of about 100 words and a summary of not more than two pages, and should be sent as plain text to <tclconference AT googlegroups DOT com> no later than August 30, 2011. Authors of accepted abstracts will have until October 14, 2011 to submit their final paper for the inclusion in the conference proceedings. The proceedings will be made available on digital media, so extra materials such as presentation slides, code examples, code for extensions etc. are encouraged. Printed proceedings will be produced as an on-demand book at lulu.com The authors will have 25 minutes to present their paper at the conference. The program committee will review and evaluate papers according to the following criteria: * Quantity and quality of novel content * Relevance and interest to the Tcl/Tk community * Suitability of content for presentation at the conference Proposals may report on commercial or non-commercial systems, but those with only blatant marketing content will not be accepted. Application and experience papers need to strike a balance between background on the application domain and the relevance of Tcl/Tk to the application. Application and experience papers should clearly explain how the application or experience illustrates a novel use of Tcl/Tk, and what lessons the Tcl/Tk community can derive from the application or experience to apply to their own development efforts. Papers accompanied by non-disclosure agreements will be returned to the author(s) unread. All submissions are held in the highest confidentiality prior to publication in the Proceedings, both as a matter of policy and in accord with the U. S. Copyright Act of 1976. The primary author for each accepted paper will receive registration to the Technical Sessions portion of the conference at a reduced rate. Other Forms of Participation The program committee also welcomes proposals for panel discussions of up to 90 minutes. Proposals should include a list of confirmed panelists, a title and format, and a panel description with position statements from each panelist. Panels should have no more than four speakers, including the panel moderator, and should allow time for substantial interaction with attendees. Panels are not presentations of related research papers. Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather sessions (BOFs) are available on a first-come, first-served basis starting in August 1, 2011. Specific instructions for reserving WIP and BOF time slots will be provided in the registration information available in June 2011. Some WIP and BOF time slots will be held open for on-site reservation. All attendees with an interesting work in progress should consider reserving a WIP slot. Registration Information More information on the conference is available the conference Web site (http://www.tcl.tk/community/tcl2011/) and will be published on various Tcl/Tk-related information channels.
