QOTW: "... use arrays when you need arrays (... elements can be traced and
linked to Tk widgets; shorthand syntax; works in all versions of Tcl). Use
dicts when you need dicts (advantages: elements can't be traced, dicts aren't
tied to variables). [array get] and [array set] provide good ways to convert
between dicts and arrays."
"... if you need traces on individual elements (for instance, to make the
elements -textvariable's of entry widgets), again arrays are your thing."
Joe English and Kevin Kenny, in tag-team pedagogy
Thanks to Arjen Markus for his weekly summary of Wiki action:
It is heartwarming to see so many applications created at least
partially with Tcl/Tk on the Wiki ... but let us not forget
the techniques used to bring them to the world!
- Why introduce new control structures? Partly because Tcl makes
it easy and partly because this is useful.
- Why use Tcl with command-line not unlike Perl's or AWK's?
Maybe because so many people want that. But don't forget
the inreractive shell Tcl provides without any fuss!
- Why contemplate an operating system that only uses Tcl
for scripting? Well, it is fun to consider what you need
for this task. And what do you know? Etlinux is almost
such a system - <http://wiki.tcl.tk/16116>
Testing, 1, 2, 3
- TkXext is an extension that is meant to help automating
arbitrary applications. Well, at least applications
based on the X Window System. <http://wiki.tcl.tk/2116>
- So there you are with your cell phone and a whole bunch
of messages ... How do you archive them? Here is a
nice little tool: <http://wiki.tcl.tk/17538>
- Visualising sounds? It is not impossible, as oscilloscope
enthousiasts know. <http://wiki.tcl.tk/8021>
- We can even use BLT to implement an oscilloscope, at least
it is able to handle large amounts of data quickly!
- Scanning the recent changes your chronicler stumbled
across a page he had completely forgotten about. Good
thing the Wiki has a better memory ...
Everything Tcl-related you want is probably one or two clicks away in these
The "Welcome to comp.lang.tcl" message by Andreas Kupries
comp.lang.tcl is a crucial resource for Tcl practitioners.
An interesting perspective on its traffic appears at
The Tcl Developer Site is Tcl's "home base".
Larry Virden maintains a comp.lang.tcl FAQ launcher.
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:
The TDX sponsor, ActiveState, also keeps info to convince your
boss Tcl is a good thing
The Tcl'ers Wiki is a huge, dynamic, collaboratively edited repository
of documentation, examples, tutorials and pontifications on all things
For the ideal overview of the topics about Tcl most likely to
interest a newcomer, see "Arts and Crafts ..."
There's also a high-quality Wikibook on Tcl:
ActiveState maintains binaries distribution and development tools
along with a Cookbook of Tcl recipes
"La Gazette du Técleux" is an important monthly publication.
deli.cio.us presents an intriguing approach to reference commentary.
It already aggregates quite a bit of Tcl intelligence.
Cameron Laird tracks several Tcl/Tk references of interest (but
needs to validate many of the links).
Years ago, Cetus Links maintained a Tcl/Tk page with verified links
"Yahoo! Groups" archives comp.lang.tcl.announce posts--even
though clta itself is dormant.
We're working on more useful archives of past installments. In the
meantime, an alternative is
