The Tcl/Java project's goal is to make integrating the Java platform and the
|
|
Tcl scripting language as easy as possible. The project actually consists of
|
|
two distinct packages, called Tcl Blend and Jacl. It is important to
|
|
understand what each package provides and in what situations one might choose
|
|
to use Jacl or Tcl Blend.
|
|
|
|
Tcl Blend is a Tcl extension that makes use of JNI to facilitate communication
|
|
between a Java interpreter and a Tcl interpreter. Tcl Blend is typically used
|
|
to load a Java interpreter into an existing Tcl process, so that functionality
|
|
implemented in Java can be accessed via Tcl. One can also load Tcl Blend and
|
|
Tcl into a Java process, which is a great way to add scripting functionality
|
|
to an existing Java application. Because Tcl Blend is a normal Tcl extension,
|
|
one can use it with other popular Tcl extensions like Tk, Expect, and Itcl.
|
|
|
|
Jacl is a self-contained implementation of a Tcl interpreter, written entirely
|
|
in Java. Jacl also includes features that facilitate communication between a
|
|
Java interpreter and a Tcl interpreter. Jacl is typically used to incorporate
|
|
scripting functionality into an existing Java application. For users who want
|
|
to avoid adding any native code to their Java applications, Jacl is the ideal
|
|
solution.
|
|
|
|
Tcl Blend and Jacl define both a Tcl API and a Java API that make it easy to
|
|
call Java code from Tcl or call Tcl code from Java. For example, one could
|
|
allocate a Java object in a Tcl script and interactively invoke Java methods
|
|
on the object. It is also easy to use the supplied API to evaluate a Tcl
|
|
procedure from a Java method or implement Tcl procudures in Java. The flexible
|
|
API and wealth of implementation options provided by the Tcl/Java project make
|
|
integrating Tcl and Java easy.
