Dr. Dobb's Tcl-URL!

QOTW: "Tcl has a long history of keeping everything open to introspection
and revision." -- Don Porter

"*ALL* IRC clients stink." -- David Gravereaux


POTW: IRC_Engine v0.1 by David Gravereaux.
IRC_Engine is "a Tcl extension for back-end IRC client control".

     Helmut Giese explores ways to tie shared memory comms into
     Tcl's channel system, so it's event-driven rather than polled:
         http://groups.google.com/groups?th=b9758a5a05c22919

     One regexp question, multiple answers.  It's c.l.t at its best!
     (Worth it just for the jaw-dropping regexp wizardry displayed.)
         http://groups.google.com/groups?th=66f7f05bc3292c12

     The folks at Slink Software have outlined in text the 8.4.4 internals.
        http://www.slink-software.com/W/SrcDoc_Top/tcl8.4.4/tcl8.4.4.sdoc/N_91

     A comparison of the internal regexp code in Tcl and Python, with
     side discussions of the stubs interface:

     If you need to distinguish the visual beginning of a wrapped line,
     as opposed to the actual beginning of the whole line, read this:

     Getting the text associated with a tag is not as straightforward
     as you might think:

     Stacking order becomes important when using [pack -in]:

Thanks to Arjen Markus for his summary of recent Wiki activity:
  A summary by categories this week:
  
  Tcl constructs
  - Regular expressions get more than enough attention in the newsgroup, but
    here is a page that can tell you about the inner workings, 
    <http://wiki.tcl.tk/9185>
  
  - Ever run into constructs that appear innocent but are not for some reason?
    Well, put them on display on <http://wiki.tcl.tk/10355> 
  
  - A pure-Tcl package to implement data with options and actions, just
    like widgets, <http://wiki.tcl.tk/10367>
  
  Graphics
  - Generating a maze or labyrinth is no problem, not even in 3D. It is 
    even possible to let the computer generate the solution. Start at 
    <http://wiki.tcl.tk/2502> and work your way through the code and
    the links to get to the "Exit" sign.
  
  - "IFS" is the innocent title of a page devoted to one class of 
    fractal generating programs. Just have a look: <http://wiki.tcl.tk/10373>
  
  Internet browsers, protocols and pigs
  - Two pages for one subject: using the Tkhtml package to view pages from
    the Internet, <http://wiki.tcl.tk/2993> and <http://wiki.tcl.tk/10368>.
  
  - Do you know the X10 protocol? If not, time to read up, I guess. It is
    all about serial ports and thingies your chronicler does not quite
    understand, but <http://wiki.tcl.tk/3889> is the place.
  
  - Okay, not so much pigs as Pig Latin: <http://wiki.tcl.tk/10356> gives
    the rules and <http://wiki.tcl.tk/10357> is the translation of the
    Endecalogue into it.
  

Everything Tcl-related you want is probably one or two clicks away in these
