Tcl-URL! Weekly Tcl News and Links (July 15)

Jul 16, 2002, 07:00 (0 Talkback[s])

QOTW:  "We have memory leaks in our C++ based extensions, and the Solaris
and Linux memory management methods can vary wildly... but Tcl is as
stable and reliable as the U.S. economy... er, how about a '63 chevy with
a 283 V8?  Yeah, as stable and reliable as a '63 chevy with a 283 V8."
        --Phil Ehrens,
        http://groups.google.com/groups?as_umsgid=agn0g9$9a8@gap.cco.caltech.edu

"I think the need for OO techniques is greatly reduced by a language with
[eval] and [info] and dynamically-sized structures built in. This may be
why you see less OO in Tcl than in some of the other languages."
        -- Darren New,
        http://groups.google.com/groups?selm=3D25CC00.59A28133@san.rr.com

"What I like about 'bgexec' is that it handles all the dumb stuff under
the hood--so you (the Tcl programmer) don't have to worry about it."
          George A. Howlett

    Michael A. Cleverly announces nstcl 1.0, "a Tcl package
    which reimplements many of the useful APIs and commands
    from AOLserver and OpenACS, making them available for use
    in Tcl/Tk applications & scripts [...]  Most notable of
    these is the nstcl-database package, and the 'ns_db' API,
    which provides a common interface to various different
    database extensions."

    Techniques for building standalone deliverables are discussed
    in the thread "Compiling or wrapping?".  Techniques covered:
    ProWrap, FreeWrap, Mktclapp, TclKit, scripted documents
    (recently rechristened "StarKits"), and StarPacks:
        http://groups.google.com/groups?th=6d20d48a615a784b

    More on Starkits and Starpacks: "Due to the many terrific
    contributions and enhancements (most of them in the Tcl core
    by now) you can now consider deployment of applications built
    upon Tcl/Tk to be 'solved'.  [...] Starkits are very close to
    becoming a 100% hassle-free deployment technology."

Thanks to Arjen Markus for his summary of Wiki action:

    After scanning a long list of changed pages, these are the ones that
    attracted the Wiki chronicler's attention:
    
    Some well-chosen words about GUIs:
    - A practical guide to fonts can be found at <http://wiki.tcl.tk/451>;
    - A pragmatic guide to popup windows is at <http://wiki.tcl.tk/3713>;
    - A programmatic aide for editing Korean characters resides 
      at <http://wiki.tcl.tk/3681>;
    - "Embedding Windows applications in Tk frames" begins to answer a
      long-standing open question <http://wiki.tcl.tk/3702>;
    
    Extending Tcl may be relatively easy, but these pages discuss the
    subject in more detail:
    - Writing Extensions <http://wiki.tcl.tk/1191>; is a page that collects
      references to other pages on the subject.
    - Here is a new one: making compilers work within scripts,
      <http://wiki.tcl.tk/3687>;
    - Well, with the approach of Tcl 8.4.0, a discussion on how to prepare
      yourself for more than one version of Tcl may be just what you need,
      <http://wiki.tcl.tk/3708>;
    
    Quite a lot is known about protecting your source code, start reading 
    all about it at <http://wiki.tcl.tk/3698>;

    And for the algorithm addicts:
    - nstcl aims at unifying the interface to many packages, like AOLserver, 
      OpenACS and sundry databases, have a look at <http://wiki.tcl.tk/3666>;
    - Interested in tree structures? e4graph may give you ideas. Follow the
      branches that stem from <http://wiki.tcl.tk/1410>;
    - An all-Tcl calculator, just to understand the inner workings, 
      by George Staplin, <http://wiki.tcl.tk/3709>;
