This restricts disallowing value types to containers that can own
them.
It also disallows usage of @owned on those view-only containers,
as that makes no sense.
You can now declare errors like this:
error Foo = "message"; [[documentation]]
Then you can use them as types like this:
foo {
return: error(Error1, Error2, ...);
}
They have a separate type category and storage. They are checked
for redefinitions the same as anything else though. This does
not add any generator support nor it adds any advanced checking.

This adds a new unified syntax for giving declarations C names.
Classes: class @c_name(Foo) Foo ...
Types: type @c_name(Foo) Foo: Bar ...
Structs: struct @c_name(Foo) Foo ...
and so on. Type instances properly inherit those. This also cleans
up some other parts of the source code.
Fixes T6716.
Summary:
The C# bindings turn parts into class properties, so part names cannot clash
with method names.
However, a "Part" prefix has been recently added, just like it was done for
events, and therefore this eolian restriction can be lifted.
With this patch part name clashes are only checked among parts, just like it
is done for events.
Relates to D8582
Test Plan: Everything still builds, because we have no part-method name clashes in the tree, but now they are possible.

This implements initial support for specifying unit versions.
The default version is 1, specifying the basic feature level.
If you want to specify another version, you need to specify
something like `#version 2` at the beginning of the .eo or
.eot file; the version number must be higher than 0 and lower
than USHRT_MAX (typically 65536).
The beginning of the file is now called the "header section";
other things may be added into the header section later.
Version cannot be specified twice, and it cannot be specified
once other contents (like types or class definition) appear.
Comments do not count as other contents, so those are fine
to appear before #version.
@feature
@warn_unused in syntax is now called @no_unused - this is because
"warning about unused" is a C thing (or rather, an extension to C)
and various languages might want to use stricter behavior for this.
Its associated API does the reverse now - it lets you query whether
being unused is allowed at all. This is to match future behavior
of Eolian (once it supports versioning) that will likely reverse it.
@feature
This has been deprecated for a while and is not strictly necessary
- as a part of an effort to stabilize Eolian, remove this. Eolian
will eventually gain support for versioning and use a reversed
behavior (i.e. no NULL by default), but the API it wlll use for
that will be very different. Features can always be added, it's
much harder to drop them.
@feature
This was an experiment that never properly took off and was never
used by any generator. Its use was highly variable, so it could
not be relied upon. We will still want to reverse the current
behavior eventually (no null by default), but that will be
done with eo file versioning in the future.
@feature
This is for consistency with the new eolian_class_c_macro_get
as well as for better clarity, as c_name_get is already provided
by Object and refers to something else.
This is to prepare for type/class renaming support. This adds
the necessary API to retrieve C-specific names. Other refactoring
is necessary elsewhere for now.
This also renames the old API eolian_class_c_name_get to
eolian_class_c_macro_get to avoid conflict as well as clarify
the intention.
This splits the eolian_file_parse API into two, one for parsing
files already present in the database (always by filename) and
one for parsing paths.
It fixes several bugs/leaks on the way (incorrect use of
stringshare etc.) as well as adds checking for whether there
are no conflicting filenames at scan time, for free. That means
it is now no longer possible to scan two paths which have an eo
or eot file of the same name in them.
It should also be faster now.
It also fixes T7820.

This adds support for inlist structs, a special type of struct
that can only be used with inlists. This differs from regular
structs in a couple ways:
1) They are stored separately. Just like structs, enums, aliases
have their own storage, so do inlist structs.
2) They can't be @extern, nor they can be opaque.
3) They are their own type of typedecl.
4) When they contain only one field, this field must be a value
type always, cannot be a pointer.
Like regular structs, they can have arbitrary fields, and they
can have a pre-set free function via @free().
In C, the inlist structs will be generated exactly like ordinary
ones, except they will have EINA_INLIST before the first field.
Other binding generators can deal with them as they wish, for
example to provide high level interfaces to them.
This does not yet do the plumbing necessary to hook these into
the type system, nor it adds generator support.

We keep a hash tracking implements that were already errored on
so that we don't print some errors multiple times. The problem is
that it wasn't getting cleared when switching to a new inheritance
tree so errors from an interface implemented in multiple distinct
inheritance trees would only get printed once.
Since _extend_impl always marks the impl at least IMPL_STATUS_NONE,
we need to retrieve the original status before calling into it,
or it will get overwritten and will inadvertently disable some
of the checks.
We worked under the assumption that when inheriting callables
from a regular class, it's good enough to just set those as
fully implemented, because the underlying class is already
checked. This assumption is wrong, as the callables may contain
multiple implements pointing at the same function (consider when
a regular class implements just the get part of a property but
some underlying class implements it whole) - the old logic would
result in just the first reached implement (possibly incomplete)
being added into callables of the inheriting class, which results
in false positives.
Consider this example:
class A has a fully implemented property foo
class B inherits from A and partially implements foo
abstract C inherits from B
class D inherits from C
abstract C would go over B's implements, encounter the first
partial implementation of foo, adding it into its own callables
and marking it as fully implemented (because it came from an
already checked regular class B), which would result in the
other implement being skipped.
So make no assumptions and use the same logic for all class types.
Of course, this brings in another problem: some errors would now
get printed twice, because if you have a class A which has funcs
that are unimplemented and class B inheriting from it, errors would
get printed for A but also for B, which would include A's errors.
To battle that, introduce a "global" (well, local to the entry
point of the validator) hash tracking which implements have already
been errored on; and skip those appropriately.
It hasn't been necessary to keep these temporary buffers around
for quite a while, nobody just got around to remove them. Eolian
has a good formattable error logging system in its core now.
Also, use same erroring style on parts as on functions, i.e.
batch-print all the conflicts at once.
There isn't any more logic necessary because checks are still only
done on regular classes; we just need to make sure that composite
lists from its inheritance tree are accounted for.

Each regular class can now have a section called 'composite',
which can contain interfaces and interfaces only. This defines
a list of interfaces that are allowed to be unimplemented on the
class, as it is assumed the class will be composited with some
other class implementing those interfaces.
Only regular classes can have this, as only regular classes can
be instantiated.
It will also be necessary to check whether the classes in the
section appear somewhere within the inheritance tree. For now,
this testing is not being done.

As per T7240, we intend to disallow multi-class inheritance in Eo
at some point. In order to achieve that, it is necessary to find
out which classes still use multi-class inheritance and change
them accordingly.
Eo multi-class inheritance is not actually multi-class, as doing
so will simply treat all the other classes as interfaces, which
is misleading and poor design on its own.
By setting EOLIAN_CLASS_REGULAR_AS_EXT_WARN environment variable,
Eolian will now warn about such classes, allowing them to be
fixed.
Closes T7365.
This new syntax separates the parent class from extensions, in
a familiar way to similar to e.g. Java. Since changing everything
at once is a lot of effort, implement it alongside for the time
being.
Eolian now separates 'parent' and 'extensions'. For regular
classes, parent is the first item in the inherits list and
extesions is the rest. For interfaces and mixins, parent is
NULL and extends is the inherits list.
The reason for this is the separation of them in syntax in near
future. It also slightly changes the behavior; since for interfaces
and mixins, parent is always NULL now, you can freely inherit from
all types of classes without needing to manually put an interface
type as the first item of the inherits list.
Previously, the EOLIAN_EVENT_REDEF_WARN environment variable
enabled extra checks that would include events in checking
conflicts against methods. Since this is probably not necessary
and naming events the same as methods is perfectly fine in itself,
relax this rule and check events completely independently.
In practice, this will disallow using the same name for two
events within the same inheritance tree, which is desirable
in longer term, but cannot be enabled just yet because we have
too many of those conflicts. But it also allows the events to
be named the same as methods or parts, which is fine and was not
possible before.
Summary:
Strings are const and if these are meant to be owned then it
should define its own special free func. Mstrings are mutable
and therefore can be owned and freed using standard free() by
default.
This fixes some warnings around the EFL caused by empty fallback
free funcs created by the eolian generator, and these mutable
strings were not being freed and potentially leaked.

This information has been stored and used in Eolian until now
but not exposed to the API user. While there are roundabout ways
to retrieve the class for an event, this one is direct and costs
us nothing.
This will make it easier for generators and utilities to retrieve
the class that implemented a method/property/etc rather than the
class the implement was originally defined for. Thanks to this
it will no longer be necessary to carry the class pointer around
the place.
Summary:
This tagging keyword explicitly asks, for bindings that support it,
that the constructor's parameters are added to the class constructor.

Depends on D7011
It is not necessary to check entire classes/typedecls/variables
when referenced, as that also checks their contents and adds
false negatives. It is enough to simply add their own unit
as a 'used' dependency and let the system do the work, besides
for actual declarations in the checked file.
This is necessary even when parsing a single file because there
may be parsed results directly in the staging area introduced by
doc references, those wouldn't get correctly validated and would
be left in an inconsistent and unusable state.
Set the EOLIAN_EVENT_NO_TYPE_WARN environment variable to enable
those warnings during Eolian usage. They will be considered a part
of the validation then.
Use the void type for events to suppress the warning.
This is necessary because inheritance trees need to be validated
individually for proper name conflict checks. It also prevents
eina_hash_add related errors.
This is much like 'import' but doesn't add the imported file into
the dependency list for the current file. This is to enable doc
reference validation to remain functional without needlessly
introducing file dependencies just to satisfy it.
The issue was that standalone-parsed files (outside of dependencies
of some other unit) were not being included in that dependency tree
(obviously) which resulted in their own dependency tree being
excluded from merging, causing the database hashes to lack the
necessary elements.
To fix this, I trigger merging of the "standalone" dependency trees
separately, by calling _merge_units from defer parsing cb.
Doc refs no longer introduce new dependencies into files. Instead,
they're parsed globally, and any doc ref lookup is also made
globally. This allows unit based dependencies to correspond more
to what files actually really need at compile time/runtime, with
docs being irrelevant to that; it also simplifies the API.
The doc resolution API now takes Eolian_State instead of
Eolian_Unit, too.
This is cleaner than adding into a hash manually. Additionally, it
is now possible to request that the file be parsed not as a dep,
but rather standalone, which will be useful later.
Eolian doc objects now bundle debug information necessary to
provide correct line/column numbers. It is not possible to get
this information cirectly from the text, as it's reformatted and
contains no extra whitespace or newlines beyond paragraph
separators.
Fixes T6701.
Previously, when an error happened in Eolian, the state was left
in a presumably unusable and inconsistent condition. This work
aims to change that, as all changes are committed into a staging
area before being validated and merged back into main state.
This is not yet complete, as units and by-file lookups are not
currently involved in the rollback. This will change in the
subsequent commits.
