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 26,
2011. Authors of accepted abstracts will have until October 9, 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.

TCLCA receives first publication rights, and expects that this is the
first time the paper is published. Not a retread from another
conference, etc. TCLCA further receives subsequent publication rights,
to handle the Publish-On-Demand nature of Lulu, our vendor for the
dissemination of the conference proceedings. All other rights are
retained by the author. You can put this on your website, include it
in a book, expand it into a novel, sell the movie rights, etc.


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.

Reservations for hotel suites can be made by calling
(703) 686-1100. Be certain to mention that you are with the Tcl/Tk
Conference to get the Tcl/Tk Conference room rate.

Hello Gustaf,

./generic/nsf.c: In function ‘ParamOptionParse’:
./generic/nsf.c:8281: warning: implicit declaration of function ‘strnstr’
./generic/nsf.c:8281: warning: assignment makes pointer from integer
without a cast
./generic/nsf.c: At top level:
./generic/nsfStack.c:1015: warning: ‘BeginOfCallChain’ defined but not used

It seems that strnstr() function is new to Linux (as of January 2010)
and is not present in many Linux libraries yet. May be you can
substitute it with something else.

Hi everyone,

When assigning an object's property using object parameters, the assign
method of that property does not get called. Is that a bug or intended
behaviour?

See the following code:

package require nx

nx::Class create Foo {
    :property bar {
        :public method assign { object property value } {
            puts "assign called for: $object $property $value"
        }
    }
}

set foo [Foo new]
$foo bar "test"; # assign method of the bar property is called

Foo new -bar "test"; # assign method of the bar property is _not_ called

Kind regards,
Arthur

Hi,

we're aware of the Windows problems with GDBM and have a new compiled
version for XOTclSdbm, a new Tcl-only TextFile Storage (both as an
alternative to Gdbm), and a new XOTcl wrapper for Gdbm ready for Windows.
We're in the last preparations for the next XOTcl release in which
our whole XOTcl test suite runs without problems under Win (including the
Counters and other actiweb apps). And the compilation process under Win is
working much better now.

I would propose to wait a few days until 0.84 is ready. If you desperatly
need it, I can send you a preview for the time being.

Greetings,

Uwe

Thanks for the interesting responses. So people are: 1) Using a broker to
associate Tk objects and XOTcl objects. 2) Using a filter to intercept Tk
commands. 3) Wrapping a Tk object in an XOTcl object.

Maybe some day we can integrate the Tk object commands with the XOTcl object
commands. I would like to help, but if I do it, I won't get to it for
years. (The part of the project that would need that functionality is that
far off.)


        Regards,

Hello,

Have had a chance to set up the actiweb framework and now trying out the
examples;-)
This is really good stuff....

Going through the readme, one would expect that I should be able access
the plain text interface via http://...path..:8091/c1, via a browser
but I get an error, in the browser.. (the counter2.xotcl example)

"invocation error: Object 'c1' unknown

Status Code 404: *Not Found*
Resource Name: c1"

and in the shell
::receiver::error ::ErrorMgr->invocationError ::receiver::start.html
{Object 'c1' unknown} {}

I would have expected that a text representation would have been
returned via .../c1
...web-c1 returns the html facade as expected...

Is this because we dont export to the receiver class, or am I missing
something else?

regards,

nicolas boretos

When creating XOTcl objects from C, it would be nice to be able to
initialize the new object's clientData prior to any methods being invoked
on the object.

Right now, the only way I can think of to do this is to
1. create the object (which invokes "init", which can't rely on the
ClientData)
2. XOTclSetObjectClientData( XOTclGetObject(), data); // Or the Class
equivalent
3. Invoke some secondary, private "init"-like method that does true
initialization

It would be nice to have two new exported functions:

int XOTclCreateObjectCl (Tcl_Interp* in, Tcl_Obj* name, ClientData data,
struct XOTcl_Class* cl);
int XOTclCreateClassCl (Tcl_Interp* in, Tcl_Obj* name, ClientData data,
struct XOTcl_Class* cl);

That initialize the XOTcl ClientData field prior to invoking "init" so
that "init" could rely on the XOTcl ClientData being valid. This would
make it much easier to construct XOTcl wrappers around C/C++ objects.

Is this reasonable? Is there a better way to accomplish this?

one can do this with a few lines of code (see below).
In most cases, it is better to name the types (like e.g.
a type isbn), such that the matching pattern/regexp does
not have to be repeated on each usage.

-gustaf neumann

==============================================
::nx::Slot method type=glob {name value pattern} {
   if {![string match $pattern $value]} {
     error "Value '$value' does not match pattern '$pattern'"
   }
}

Class create C {
   :attribute x:glob,arg=*world
   :public method foo {a:glob,arg=*x b:glob,arg=*y} {
     return $a-$b
   }
}

#C create c1 -x abc; #Error: Value 'abc' does
not match pattern '*world'
C create c2 -x "hello world"
c2 foo xxx yyy
#c2 foo x aya; #Error: Value 'aya' does not match
pattern '*y'

How about adding two move predefined constrains?:

:attribute a:regexp={myregexp}
:attribute a:glob={myglob}

Thanks
