http://sf.net/projects/tcljava/ is the home for [TclBlend] as well as Jacl.  Jacl is an alternate implementation of Tcl, this time written entirely in Java.

According to this InfoWorld article[http://www.infoworld.com/article/03/06/12/HNsunscripting_1.html],
Sun is thinking of introducing scripting to Java.  Shouldn't they be encourages to do this with Tcl?

See http://www.tcl.tk/man/java1.2.6/TclJava/contents.html for online
documentations.

There is a mailing list at the web site which provides support for Jacl
[mailto:tcljava-user@lists.sourceforge.net].


----
As of September 2001, [Neil Madden] has what he calls a rudimentary
implementation of [socket].

Several Jacl-oriented stories have been published through the years,
including
"Extending [XML] tools with Jacl scripts"
[http://www-106.ibm.com/developerworks/library/x-xjacl/?open&43,t=gr].

Also, recently mentioned on the mailing list was these articles:
http://www.projectgalileo.org.uk/audela/quiveu7_en.htm
(see "Tcl + Java = A match made for scripting" ), as well as

[CL] occasionally updates a page
[http://phaseit.net/claird/comp.lang.java/jacl.html]
of information related to Jacl.










----
[Swank] is an interesting extension to Jacl.

[Neil Madden] writes,
"To try out Jacl, make sure jacl.jar is in your classpath (it should be from what
you say), and then open a command line and type:

    java tcl.lang.Shell

after a second or so you should see the familiar % Tcl prompt and you can fire
away. If you want to extend your Java application using Jacl, then just import
tcl.lang.* and look at the docs which come with Jacl for some pointers at how to
use the APIs."

[Martin Lemburg] I'm experimenting the first time with Jacl and have following problem.

I evaluate a tcl script inside the Jacl interpreter and the result is following:

    {"" "platform information:" {os {Windows 2000}} ...}

I want to test if an object inside the list is a list or something else by this: 

  1    TclObject     result, element;
  2    TclList       list, subList;
  3    ReflectObject reflectObj;
  4
  5    result     = ip.getResult();
  6    element    = null;
  7    list       = (TclList) result.getInternalRep();
  8    subList    = null;
  9    reflectObj = null;
 10
 11    for ( int idx = 0 ; idx < list.getLength( ip, result ) ; ++idx )
 12    {
 13        element    = list.index( ip, result, idx );
 14        reflectObj = (ReflectObject) element.getInternalRep();
 15
 16        if ( reflectObj.getClass == TclList.class )
 17        {
 18            // ... use as list ...
 19        }
 20        else
 21        {
 22            // ... use as "not" list ...
 23        }
 24    }

When casting from the internal representation of the first element of the list - here an empty string - to the ReflectObject type (in line 14) I get the exception "java.lang.ClassCastException" (detailMessage: "tcl.lang.TclString")

So I experimented a bit and I tried just to get the ReflectObject of the internal representation of the interpreter result and I got the same exception "java.lang.ClassCastException", but with the detailMessage: "tcl.lang.TclList".

I used the verbose option of javac ... javac loaded the class tcl.lang.ReflectObject.
I used the verbose option of java ... java didn't loaded the class tcl.lang.ReflectObject.

So what can I do? What goes wrong?

Thanks for any hints, suggestions!

Best regards

Martin Lemburg

[Martin Lemburg] again ... I found the errors, many errors. Here my "new" and working version:

  1    TclObject     result, element;
  2
  3    result     = ip.getResult();
  4    element    = null;
  5
  6    for ( int idx = 0 ; idx < TclList.getLength( ip, result ) ; ++idx )
  7    {
  8        element    = TclList.index( ip, result, idx );
  9
 10        if ( (element.getInternalRep()).getClass() == TclList.class )
 11        {
 12            // ... use as list ...
 13        }
 14        else
 15        {
 16            // ... use as "not" list ...
 17        }
 18    }
