I think for many, "teens" starts at 10 (rather than 13), so 2010-2019
would be the "teens" of the new millennium.
nevermind, many people apparently believe that the world will end in a
few months from now.
as for the topic:
I just kind of find it funny, I express some annoyances with the JVM:
lack of value types, awkward FFI, ...
people then make a fuss about it, counter-arguing (unnecessary, wouldn't
help, ...).
Oracle then goes stating plans to go work on it.
even more funny would be if they added extensions for pointers and RAII
and similar, but this seems less likely.
it was not stated what sort of FFI design Oracle is considering.
in my own VM/language, I did like this (a boilerplate-free FFI), and
used an HLL-level interface for importing roughly like:
native import C.stdio; //import C's "stdio.h"
actually, it doesn't directly import the header (the actual mechanism is
more convoluted, as it aliases the header-name to a target-specific
library-name, and imports the library instead, and the contents of the
"headers" are aliases to a DB keyed with the same name as the library).
(say, "C.stdio" maps to "msvcrt.dll", and loads the "msvcrt_meta" DB).
the "C." prefix basically indicates the intended target language (of
which, C is the currently only supported option).
exporting works more like:
native package C.foo
{
struct SomeStruct
{
...
}
...
function somefunc(x:int):void //takes int, returns void
{
...
}
//takes C-string, returns struct pointer
function somefunc(str:cstring):*SomeStruct
{
...
}
...
}
with anything declared within the package being exported to C land, and
expected to conform to C-friendly rules (the language also has pointers,
for sake of easing C interfacing, which have a syntax like "x:*void;").
pardon the strange syntax.
the mechanism in this case currently involves using a tool which spits
out headers and C-based glue-code though (which are then compiled and
linked with native code), as I do not yet know of a clearly better
option here (C lacks late-binding...).
a Java analogue could be, say:
public native class Foo
{
...
public static void somefunc(int x)
{
...
}
}
with any static methods within the class being exported as native C or
C++ functions or similar.
maybe also doing direct cross-language class-to-class mappings, like in
GCJ (where class-members can be identity-mapped across the language
boundary).
or such...
