As an alternative to what Goktug proposed about macros, we would have an
equivalent to Scala macros (sorry for insisting with Scala :-) )
@Macro(SumGenerator.class)
Integer sum(Integer arg0, Integer arg1) {
// We will never be here
return null;
}
// rebind space
class
My original motivation was like the String.format() case, but with
GwtQuery's $() function, since GwtQuery supported compile-time CSS selector
parsing, is was really tedious to add them to an interface when all you
wanted was $(.foo h1.title) or some such. Later, when doing GWT

APT is missing mostly whole-world kind of informations in TypeOracle (e.g.
getAllSubTypes) but perhaps this is also advantage and that is why it help
the compiler to scale better :) Also looking at the usages
of getAllSubTypes it is not like a major deal if we replace GWT-RPC with
something that

Today, even GWT generator developers are having trouble debugging generated
code with -gen (just think GWTTestCase). It is not very practical for every
day usage of end users.
I don't know how well APT support of IDEs are today but that's something
that IDE's itself can improve upon and we can
There aren't really two concepts: you can mix and match generate-with and
replace-with for the same type, and/or switch from one to the other over time.
Actually, replace-with is only a shorthand for a generator returning a constant
value (of a class that already exists).

I don't think APT is good enough. Java8 has a compiler plugin API for
code-gen that might work. APT has limitations that make it problematic to
replace generators. Stephen Haberman brought this up at the GWT meetup.

This reminds me a lot of Scala macros research. As you probably know, Scala
solves code-gen issues with experimental support for several kinds of
macros, distinguishing clearly between expression-level and type-level code
generation/rewriting.
APT covers only a fraction of type-level
I miss this line in my dagger example:

Now that I understand it (hopefully), I think Ray's proposal is a good way
to define new API's by writing Java wrappers that configure generated
objects at runtime. Adding parameters to GWT.create() calls seems somewhat
orthogonal as a way to pass arguments to generators at compile time.

Hi, I've published a document [1] with my thoughts on some of the
GWT.create() proposals. This doesn't cover everything we've discussed but I
think it's a start. If you're on this mailing list you should be able to
comment.

think this one should not have anything to do with GWT.create. We can do
any class replacement in compiler without
