My understanding of scripting (vs. interpreted) language is that for
scripting language byte compiler (or precompiler if you wish) is an integral
part of run-time environment. So you effectively can load source code at
run-time and execute it. This holds true for many languages, including
various Lisp/Schema implementations, even Smalltalk (except for end products
stripped off original environment). Not true for Java as it does not allow
to distribute bite-compiler related classes (part of JDK, not JRE), and even
then this integration there is not well documented.
Funny how all Emacsers call Elisp a 'programming' language and not
'scripting' language (though it IS scripting). Is it because it has that
huge development support environment which is being considered 'OS' by
itself (and Elisp is not used outside of it)?
Same would probably hold true for Java once JavaOS is complete and
Shell is on the other hand is still considered 'scripting' environment.
May be it's a matter of preference how you call it?
One more explanation of 'scripting' language could be that any program
written in it requires some environment to run in which is not simply a
language interpreter but more like a complete usable application itself.
