Previously one API used just virtual (incorrect) and one used
virtual_pure (which just sounds weird). So unify with a single
name, pure_virtual, similar as in other lanugages.
This does not change eo file syntax yet.
Now all error/unknown/etc values returned from APIs are zero,
previously it was a mix of zeroes and minus ones. Also, some
enums that had no error/invalid value before have one now, which
allows for better distinction between what is an error and what
is an intended result.
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).
@feature
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
This allows generators to silence type errors in validation in order
to reduce duplicate error messages when generating multiple files.
Also adjusted the C generator to only emit type errors when generating
Eo header files.
@feature
It's now generalized to work properly with legacy functions
as well as correctly append suffixes. Thus, it can be easily
used with the documentation generator and in other places.
@feature
Sorry for last minute new API, but this one is necessary to implement
proper verification of references in docs, which I would like to have
in 1.15. It allows you to retrieve any kind of declaration by full
namespace, so that you can check for an existence of an Eolian decl,
rather than checking every type individually.
@feature
Sometimes it is necessary to specify a different set of values for a
getter or a setter. This commit allows such specializations. This also
renders @const_get and @const_set useless (soon to be removed).
To function correctly, this required adjustment of several public APIs
as well as deprecation of eolian_function_parameter_get_by_name.
This function was not used in any generator and was pretty much
useless in the first place, so it was removed.
