Is there a reason that the 'cd' and 'pwd' commands use a value within
Interp rather than setting and getting the system property "user.dir"?
I haven't tried, but I assume that if the user.dir property is adjusted
then attempting to open a file from within the Java portion of the
application will
Hi!
In my Jacl application, users may write Tcl scripts to manipulate database
objects:
prompt% set o [createRect 0 0 20 30]
java0xcf
However, if a script is to be written that is associated with a specific
object, then that objects id (the java0xcf name) must be persistent and
stored when the
I noticed a problem when switch from 1.1a1 to the next version (which
was...?) in that source'ing files was orders of magnitude slower. Now,
I didn't take the time to determine if it was the file sourcing itself
of calling all of the commands (which were java extensions loaded
on-demand) or
I just ran a test of Jacl 1.1a1, 1.2.3, and 1.2.4 and they all had
nearly identical results (+/- 0.1 seconds). (I'll be happy to test 1.1
if I can get a pre-built version.)
My only guess is that a change I made between now and the last time I
tested against 1.1 (which was the version I saw the
How would I do it in Java? This is what I have now...
tclObject = ReflectObject.newInstance( interp,
this.getClass(), this );
tclObject.preserve();
Would it be as simple as
interp.renameCommand( tclObject.toString(), "rect20" );
Should the following work?
namespace foo {
variable x
set x 12
proc y { a } {
puts $y
}
}
I get an unrecognized arg foo, should be eval, etc. Looking at the code it
sure seems like this won't work.
How do I create a namespace then?

Try this.

possibilities:
1) Rework the commands. At the same time, produce a set of stub classes
matching the old ones that simply call the new class.
2) Write a bunch of Tcl procs that accomplish the same thing.
In general though, does anyone have any clever ideas for versioning
commands?

Actually, you can use Jacl in an applet; at least in Netscape. By using the
Java 2 plug-in there is a finer-grained security mechanism called
"policies." By setting the correct policies, an applet can get permission
to read files from jars (such as init.tcl) and examine classes (like using

I actually like the feature of looking for and loading classes from the jar
files. As long as I can still do this through an alternative method (such
as TCL_CLASSPATH) it'll work. I can see the benefit of such a system.

I think, actually, that in 1.2 at least if the System property "user.dir" is
set appropriately that is where the Runtime.exec() takes place. I modified
Interp.setWorkingDir() appropriately (which is called by CdCmd.java):
if (dirObj.isDirectory()) {
workingDir = dirObj;
As you know, Mo, I have also had a tough time figuring out what is *bad*
about passing in obj.getClass().
I can understand if there are methods that you don't want to expose to the
user in the derived class. In your example, if I wanted to prevent C.exit()
from being callable I should pass in
Can someone send me a pointer to where I can download autoconf 2.14.
I just checked out tcljava from sourceforge and would like to make it.
There aren't any instructions on doing this so I am assuming that I:
1) autoconf configure.in
2) configure
3) make

ing the cygnus tools. 3) The line in the
Makefile
@echo "# Making tcljava.build"
gives me an error about an unterminated quoted string. Not sure why.
Am I just being clueless here?
That said, it appears that I have built jacl.jar and tcljava.jar
successfully.

Can I request that the method Interp.evalURL() be made public? Perhaps
there's another way to accomplish the equivalent functionality or some
reason it's not already?
