Dr. Dobb's Tcl-URL!

QOTW: "I would like to state, that I really like the TCL framework
for channel and event systems.  And the documenttaion is excellent.
Just from the man pages I could create a full fledged working
channel driver with event source in a day." -- Klaus Robert Suetterlin

"Why does I/O have to be so complicated?" -- David Gravereaux


POTW: IOCP socket channel driver for WinNT/2K/XP v1.1 by David
Gravereaux.  "This is the second release of a new sockets channel
driver for windows."  "[It] uses overlapped I/O with completion ports
over the existing Win3.1 style of WSAAsyncSelect."  "It has excellent
server performance and should be at least 4-6 times faster without
any errors when operated as a high load server."

     Things to keep in mind if you want to run a script from cron:

     Accessing arrays via upvar and nested $name(key$idx) can
     seem pretty complicated, but it's really as simple as can be
     expected once you understand what's going on:
         http://groups.google.com/groups?th=d4f54b6d51ef4e22

     Does [event generate] know about keysyms for keys not in the
     current keyboard layout?

     A channel driver writer has questions about multiple interps;
     the helpful denizens of comp.lang.tcl have answers:

     Using [switch] to parse command-line options:
         http://groups.google.com/groups?th=4cfacab094c637fb#link5

     Should the [glob] gun always shoot rubber bullets just because
     you might have it pointed at your foot?  The bullets in this case
     are files that start with ~ and thus look like "home directories",
     and your foot is [file delete]:

     TIP #171 proposes to change the default <MouseWheel>
     bindings to work more like what most users expect:

Thanks to Arjen Markus for his summary of Wiki activity:
  Spring time in the Northern hemisphere! Newly born lambs in the meadows,
  chicks that got out of the eggs just in time so they won't immediately
  fall victim with the coming Easter ... And plenty of activity on the
  Wiki!
  
  Techniques
  - Talking of Easter, here is a way to calculate the date for next year:
    <http://wiki.tcl.tk/8915>
  
  - Do not carry a lot of GIF files around: turn them into Tcl code 
    instead - <http://wiki.tcl.tk/2897>
  
  - ... and put all your code into a Tcl-only self-extracting archive:
    <http://wiki.tcl.tk/11035>
  
  - Who needs more than 25 lines of code to work with XML? Well, not 
    Keith Vetter, as he illustrates at <http://wiki.tcl.tk/11020>
  
  - Yet another minimal solution: OO techniques in no more than 50 lines,
    thanks to George Staplin, <http://wiki.tcl.tk/6196>
  
  User-interfaces
  - Here is a Tcl/Tk-based window manager, <http://wiki.tcl.tk/4492>,
    updated to the latest Tcl flavour
  
  - A simple file manager, just what you might be looking for:
    <http://wiki.tcl.tk/11065>, with a bit of customisation you can 
    probably tune it to your needs.
  
  - If all you need is a textual display, maybe you can use this
    minimal version of "curses", <http://wiki.tcl.tk/10877> which
    can show a banner taken from <http://wiki.tcl.tk/11058>
  
  Round-up
  - The Tclet plugin can be used with a whole collection of software
    - catalogued at: <http://wiki.tcl.tk/11066>
  
  - Computer scientists can learn a lot from their predecessors:
    here is a small script by Richard Suchenwirth that analyses simple
    sentences and allows questions to be asked - <http://wiki.tcl.tk/11062>
