ANN: Jekejeke Prolog 1.0.9 (Java auto loading)

Dear All,

We have just uploaded the new release of Jekejeke Prolog. We were mainly 
improving the module system:

- Richer Foreign Function Interface:
Besides introducing a new data type of small floats, denoted by the "0f" 
prefix, we have also extended the foreign_XX/3 directives. Its now 
possible to register Java methods and Java fields as evaluable 
functions, and Java constructors and Java fields as predicates.

- Prolog Text Auto Loading:
A qualified predicate or evaluable function call will automatically load 
a module if it hasn't yet been loaded. Currently modules names are first 
looked up in libraries. This means the following works now:

    ?- basic/lists:member(X, [1,2,3]).

If a module name is not found, an empty module whos members are 
automatically public is created. This means the following now works as well:

    ?- [user].
    foo:bar.
    ?- foo:bar.

- Java class Auto Loading:
Additionally a module name is also looked up in the Java class path. If 
a corresponding Java class is found, this Java class is made available 
to the Prolog system. Here is an example how the Java class 
java.lang.Math is automatically loaded:

    ?- X is java/lang/'Math':'PI'.

And here is an example how the Java class java.lang.System and 
java.io.PrintStream are automatically loaded:

    ?- java/lang/'System':out(X), java/io/'PrintStream':println(X,'abc').

When a Java class is automatically loaded foreign_XX/3 directives are 
automatically placed. For overloaded Java class members branching code 
is generated which also respects specificity of argument types and 
inheritance of Java class members from the super class.

Happy coding!
