Instead of
Other.Class.some_prop.get;
Other.Class.some_prop.set;
you can write
Other.Class.some_prop { get; set; }
The other syntax is deprecated from now on.
Both variables and constants can have extern on them (it means the same thing
as in types, they won't get generated in C). This is different from the previous
semantics which only allowed extern on globals, which makes no sense.
Both globals and constants are allowed to have a value (previously only
constants were); constants are required to have a value. Globals having
a value is just a convenience for initialization during source generation.
This is unlike the previous behavior, where the value was optional for both
globals and constants and only allowed when not marked extern, which makes
no sense either.
Obivously, even when globals have a value, they're not allowed to be used
in expressions, as they cannot be evaluated at compile time (they're mutable).
Future is the read only side of a Promise. For now, I am not removing
Eina_Promise until everything is in place, but eventually the promise
type of eolian will be gone.
Adds two new type types, STATIC_ARRAY and TERMINATED_ARRAY. Static arrays are
only allowed as struct members right now - they translate to regular C static
arrays (allowing them elsewhere wouldn't be good, as C isn't very good at
working with the size information). Terminated arrays are basically sequences
of data terminated at the end. The base type of static arrays can be any type
that is not marked ref (explicit ref may get allowed later). The base type of
terminated arrays has the same restriction plus that it has to be either
implicitly reference type (i.e. translating to pointer in C), integer type
or a character. In case of ref types, the terminator is NULL. In case of
integer types, the terminator is a zero. In case of character types, the
terminator is also a zero (null terminator like C strings).

Somehow, there was code in the tree that apparently isn't tested at all, even
once - if it was, the eo.c logic that performs inheritance checks would be
triggered. I don't know how this could have happened (actually I do, it's
Cedric's fault and he should be publicly shamed for it) but these checks
make sure this will never happen again. But since the code itself appears
to be untested, I don't know if there isn't any other brokenness in it.
But that's beyond the scope of this change, so for now, let's make sure
all our inheritance is at least formally correct.
Also, enable eo_interface.eo generated code in Eo itself so that Eo.Interface
can be used when inheriting.
@fix
Inner type can now be retrieved as a base type of the type.
If the type has two inner types or more, there is a new API that allows you to
get the second inner type by calling it on the first one (same would apply to
getting third via second etc.).
This API is simpler to use and doesn't require an iterator.
It's now possible to mark struct fields and function params as "references",
which causes them to become pointers in C (in bindings, they become whatever
is necessary). They're not a part of the type and are much more restricted
than pointers, allowing bindings to be easier. This system will be gradually
utilized and expanded as required.
@feature
Complex types (i.e. list, array, hash, accessor etc.) now do not require
pointers with them anymore (the pointer is implied) and the same goes for
class handles. Eolian now explicitly disallows creating pointers to these
as well. This is the first part of the work to remove pointers from Eolian
completely, with the goal of simplifying the DSL (higher level) and therefore
making it easier for bindings (as well as easier API usage).
@feature
This adds env var EOLIAN_PROPERTY_DOC_WARN which enables extra
warnings for properties that don't have a general doc but have
getter/setter doc. This will eventually become an error and
will be enabled by default. For now it's too verbose.
Previously events used to use class name as a prefix and ignored eo_prefix
when specified. This is no longer the case. Events follow eo_prefix by default
now. In order to get around this for classes where this is undesirable, a new
field event_prefix was added which takes priority over eo_prefix. If neither
is specified, class name is used like previously.
@feature
Add a promise object to allows Eolian interface to include promises
as a way to have asynchronous value return and composibility.
The usage is like this in a .eo file:
class Foo {
methods {
bar {
params {
@inout promise: Promise<int>;
}
}
}
}
Which will create the following API interface:
void foo_bar(Eo* obj, Eina_Promise** promise);
and a Eina_Promise_Owner for the implementation, like this:
void _foo_bar(Eo* obj, Private_Data* pdata, Eina_Promise_Owner* promise);

Reverting this at Felipe's request following my email. There are many
things I strongly object to in this commit. I've touched the surface of
those on the ML (which doesn't work at the moment), though we need to
better discuss it.
The gist:
1. dlsym is a really bad hack that is not even needed.
2. I don't see why eo should even be aware of promises. It's not aware
of list, hash and etc.
3. The eolian changes were done wrong.
This should have been discussed and consulted before done, even if only
because of the amount of hacks it includes and the cross-domain (ecore,
eo and eolian) nature of it.
This reverts commit f9ba80ab33.
Add a promise object that allows Eolian interface to include promises
as a way to have asynchronous value return and composibility.
The usage is like this in a .eo file:
class Foo {
methods {
bar {
params {
promise: Promise<int>;
}
}
}
}
Which will create the following API interface:
void foo_bar(Ecore_Promise** promise);
and the equivalent declaration for implementation.
However, the API function will instantiate the Promise for the
user and the implementer of the class.
