difference." - fjbuch in c.l.t, after being tentatively placed on a school bench

you can test it." - Donal K. Fellows

ANN: Tkhtml3 Alpha 10
There is a new Tkhtml3 alpha release available for download. This
one is named "alpha 10". This alpha release features quite major
improvements to the rendering engine, both in terms of accuracy
and speed. Stability has also improved a lot since alpha 9.
Tkhtml3 is a Tk widget that displays HTML documents formatted using
CSS. The Tkhtml3 project also develops a lightweight web browser,
"hv3":
Using hv3 is the quickest way to assess the capabilities of Tkhtml3.
Tkhtml3: http://tkhtml.tcl.tk
Hv3: http://tkhtml.tcl.tk/hv3.html
Changelog/Bug reporting: http://tkhtml.tcl.tk/cvstrac/timeline
There is also a mailing list. Details are on the website.
ANNOUNCEMENT New package available ( txmbox by Robert Joy ;-)
txmbox is an attempt to provide a general purpose informational
dialog tool to replace tk_messageBox. txmbox adheres to all the
tk_messageBox options, improving on many of them. Also, txmbox
adds so many additional features that you may never need to build
another informational dialog box. txmbox is a pseudo widget.
The only exception to compatibility with tk_messageBox; the default
for -icon is to not display an icon.
You can get more information about this tool at
http://wiki.tcl.tk/16691
OR you can simply download the tool at

Thanks to Arjen Markus for his report on the Wiki:
You can find the usual mixture of topics on the
Wiki like almost any week of the year. So let
the summary begin!
Visual bits
- Scanning pictures never was easier ...
All you need is the right hardware and the
right software - <http:/wiki.tcl.tk/16697>
- Wub may be the next incarnation of Tclhttpd
- both web servers written in pure Tcl.
- <http://wiki.tcl.tk/15781>
- Using a real programming language to create
a (visual) illusion? Why not?
<http://wiki.tcl.tk/16687>
- An easier way to create a web site?
WBuilder may be just what you want
<http://wiki.tcl.tk/16674>
- Quite enlightening, these little snippets
of code and their visual results ...
The French Wiki features the basics of
a few Tk widgets - <http://wfr.tcl.tk/1207>
and <http://wfr.tcl.tk/1210>
Computational bits
- Streams (lists of data that become available on
request) are a powerful concept. They are the
basis of "flow-based programming"
<http://wiki.tcl.tk/3356> and
<http://wiki.tcl.tk/16266>
- For those among us interested in logic and
the foundations of computing, yet another
lambda implementation: <http://wiki.tcl.tk/16695>
- For those among us interested in distributed
computing, here is a simple example:
<http://wiki.tcl.tk/16675>
Everything Tcl-related you want is probably one or two clicks away in these
pages:
The "Welcome to comp.lang.tcl" message by Andreas Kupries
http://www.purl.org/net/tcl-welcome
comp.lang.tcl is a crucial resource for Tcl practitioners.
An interesting perspective on its traffic appears at
http://groups.google.com/group/comp.lang.tcl/about
The Tcl Developer Site is Tcl's "home base".
http://www.tcl.tk
Larry Virden maintains a comp.lang.tcl FAQ launcher.
http://www.purl.org/NET/Tcl-FAQ/
The Tcl Developer Xchange is a highly organized resource center
of documents and software with provisions for individuals to
maintain references to their own software:
http://www.tcl.tk/resource/
The TDX sponsor, ActiveState, also keeps info to convince your
boss Tcl is a good thing
http://www.tcl.tk/scripting/
The Tcl'ers Wiki is a huge, dynamic, collaboratively edited repository
of documentation, examples, tutorials and pontifications on all things
Tcl.
http://wiki.tcl.tk/0
For the ideal overview of the topics about Tcl most likely to
interest a newcomer, see "Arts and Crafts ..."
http://wiki.tcl.tk/969
There's also a high-quality Wikibook on Tcl:
http://en.wikibooks.org/wiki/Programming:Tcl
ActiveState maintains binaries distribution and development tools
http://www.activestate.com/Tcl
along with a Cookbook of Tcl recipes
http://aspn.activestate.com/ASPN/Cookbook/Tcl
deli.cio.us presents an intriguing approach to reference commentary.
It already aggregates quite a bit of Tcl intelligence.
http://del.icio.us/tag/tcl
Cameron Laird tracks several Tcl/Tk references of interest (but
needs to validate many of the links).
http://phaseit.net/claird/comp.lang.tcl/
Years ago, Cetus Links maintained a Tcl/Tk page with verified links
http://www.cetus-links.org/oo_tcl_tk.html
"Yahoo! Groups" archives comp.lang.tcl.announce posts--even
though clta itself is dormant.
http://groups.yahoo.com/group/tcl_announce/
Previous - (U)se the (R)esource, (L)uke! - messages are supposed to be
listed at *Dr. Dobbs*, but sysad at CMP has fallen behind. We're working
with them to restore the archive.
