WEBINAR: On-Demand

No-Size-Fits-All! An Application-Down Approach for Your Cloud Transformation REGISTER >

Larry and his crew update thousands of links on hundreds of Wiki pages,
scores of Tcl-ers are in transit to and from the Vancouver conference,
8.4.0 makes its public release--it's been a busy week.

QOTW:  "OTOH, tcl is so flexible that you feel constrained in other languages."

"All praise Kevin Kenny for TIP#7!"  Donal K. Fellows

"Eventually, XML+XSLT will almost be as good as what IBM invented and
standardized 15 years ago, but which was considered 'too complicated'. :-)"
                                     Darren New   

    Lots of discussion this week on "Things to consider for future Tcl
    enhancement".  Features lacking, present, or "sort of" there, and
    what else we need to make Tcl even better. Michael Tiller leads off
    Highlights include Donal's summary:,1017785257,1017416912,1017410325,1016953452,1017821044,1017812887,1017743954,1017726323,1017725563,1017500209,932738815&
    ...and Chang Li's take on what we could use from Python:,932738815,1017322550,1016934670,932740266,932686001,1017809803,1017720624,1017806945,1017560107,1017539890,932733866&
    Chang Li also suggests a "cexpr" with more C-like notation to replace
    or augment "expr".
    surfaces as an interesting patch to the core of Tcl that extends
    the expr command with many of the features discussed in the thread. 
    Of course, I couldn't let this pass without mentioning
    with yet another way to extend expr using "compute".
    Michael Schlenker adds functionality from Unix to Windows:
    DB and George Staplin discuss use of anti-aliased fonts:
    and a lively discussion about how Tcl interacts with various window
    Jeff's Hobb's summary is especially worth reading:
    Toucan 1.2.1 is out there to help you develop apps for your Palm
    Pilot using Tcl:
    The latest and greatest SnackAmp, using the snack extension to play
    most anything worth listening to.
On the Wiki:
    The clearing house page has new info (and a lot of old info well
    worth reviewing):
    Packed decimal arithmetic and other options for really _big_ numbers:
    Rather not use Tk, but still like Tcl?   
    The GUI Builder page has been updated:
    How to contribute software to the Tcl family?
    Displaying html text?
    Techniques for the Internet (and more):
    - Tclhttpd is the nifty Tcl application that serves as an Internet server,
      but is also a handly framework, if you need an application with an HTTP 
      interface, <>;
    - Not only client/server but also the peer-to-peer style of communication
      is possible. A bunch of techniques and complete solutions at 
      <>; and its companion, <>;.
    - Even television networks have made into the Wiki, though perhaps this 
      poem based on a British puppet series, will inspire only Tcl'ers 
      with small children, <>;.
    Places that collect Tcl/Tk applications and extensions:
    - As the Neosoft archive will soon disappear from the Internet,
      Procplace is the new archive to search. Some assistence wanted though,
    - Steve Cassidy is working hard to get CANTCL (as described in TIP #55) 
      up and running, have a look at <>;
    Programming tips and tricks:
    - Need to set an environment variable under UNIX or Windows? This
      venerable page tells the story, <>;
    - Use a certain style whenever you program, the classic style guide for
      Tcl is described here: <>; together with all the
      good reasons as yo why to adopt "a" consistent style.
    - You may need more precision than offered by a "double", then Mpexpr
      is your friend. Or a Tcl-only solution.
      <>; and <>;
    We can not leave without some graphics:
    - Richard Suchenwirth came up with a small chess game, for two (human)
      players and perhaps, when the Tkchat gets an update, for any one to
    and if that interests you, check out
    - Building a graphical user-interface is supported by various
      applications, <>; offers an overview
    - Scrollbars are only useful when needed, a basic approach to this
      can be found in <>;
