Just for fun. I have added a few interpreter like commands to my
application. Actually online entry of code and then compile and go,
really pretty awkward. But if its pretty basic stuff maybe a quick
test. Prior diddlers have include doJava to compile and run java,
osascript for AppleScript and rexx for the Regina rexx compiler.
Following recent discussions of the Cocoa Java bridge I tried that
for the fun of it. This has no useful bearing on the prior bridge
discussions, I
guess making this of value for a limited duration. Unless someone
hacked all the Cocoa and Java introspection necessary to keep this
working. I'm guessing it utilizes the introspection features of both
languages with some JNI thrown in. That not a real educated or real
lengthily thought out guess. If anyone cares to speculate more
knowledgeably about how the bridge works I might be curious to see it.
Anyhow again for fun. the cocoa diddler. I add a automatic
autorelease pool, otherwise even just starting it and ending it
immediately gets error messages.
