Hi Alex, > BTW, how can I access existing objects (like "java.lang.System.err") > in wl? I can only find 'jnew', which creates new objects.
Like this: (jfield `(jclass "java.lang.System") 'err) There are some useful functions defined in java.wl file, implemented in picolisp instead of in native java. Basically, because Java objects are first class citizens in the wl interpreter, I need very little special purpose native functions and the rest can be build on top of that in picolisp. > It is just that I've put much more stress on execution speed, as I > possibly want to use ErsatzLisp in real applications (e.g. Android > apps) if I find the time. Well, to be pedantic in regards to speed optimisations, whenever you do something class specific you perform a class lookup based on the class name passed in: e.g. (java "javax.swing.JFrame" T "Animation") or (interface "java.awt.event.MouseListener" ... In wl, there is no need for this because I can do this at read-time, like the above example: `(jclass "java.lang.System") Also, I can do it only once, see the 'import' function and how it is used in swing.l and swt.l.
