We have to use void in a function declaration if we want no function
parameters. Using just empty parenthesis means the function takes an
unspecified number of parameters.
We had it correct for most declarations and this series fixes it for
the rest.
This doesn't quite work yet as path sanitization needs to be done for it to
work correctly. For now this code path is disabled and will be enabled once
all paths are correctly sanitized.
This is kind of ugly, but I didn't see a better way to do it without turning
this into a much more complicated parser. So this will have to do unless we
find something else to add, in which case a new doc parser will be required.
@feature
Eo files will now fail to compile if a cycle is detected.
This required some temporary changes in existing eo files
(we had 2 cycles) for which I added a FIXME (they do not
affect C generation).
@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.
@fix
This patch adds a list of strings called 'ctor_of' to
_Eolian_Function. This list will contain all classes in which this
function is a constructing function.
ctor_of is filled in two moments:
* When filling the constructors of a class, class->full_name is inserted
in the 'ctor_of' of each constructor's function.
* When filling the implements of a class, if the function is a
constructor of its superclass it also becomes a constructor of the
current class, so class->full_name is also inserted in the 'ctor_of'
of each implement's function.
eolian_function_is_constructor gets a func and klass arguments. It goes
through ctor_of of func and returns EINA_TRUE if klass->full_name is
found, otherwise it returns EINA_FALSE.
Now they're registered correctly. Also, add new API, eolian_implement_is_virtual.
Also, deal with get/set properly (when filling in additional implements)
This adds a few new APIs to retrieve the type of an expression, operators
for binary and unary expressions, lhs/rhs for binary expressions, expr for
unary expressions and value for other expressions.
Because of Eina_Value being less than optimal in our usage, we're dropping it in Eolian.
This simplifies the code and makes it easier to bind to other languages, which
will aid new generators. Also, we're dropping long double support from eo files
and expressions as it causes an ABI breakage in gcc 4.4.
I don't know what I was thinking, struct and enum fields need to be ordered
so now we keep a separate list around containing the field names in correct order.
Nothing parses yet, and no API is exposed. Also, move the remaining instances of file
inside of existing structures to Eolian_Object and parse basename only once.
This commit also does several side (related) changes. Particularly, it updates
the Eolian C generator to use the new API, it adds missing expr types (null, char)
and masks, updates the API dealing with default return values to use expressions
instead of strings and does several fixes (mainly in lexer) around the place.
It also disallows single quoted strings as those are reserved for characters.
For this purpose, several other changes were made. There can now only be 1 class per file
and the class name has to match the file name. Also, I replaced the list of classes with
a hash, allowing for fast indexing (crucial for parser performance - otherwise it was
very slow).
This also adds a new API, eolian_type_class_get.
This new API supports function pointer types, multiple type subtypes, const attribute without parsing
the name string, own attribute for any partial type and more. This commit also updates the C and C++
generators so that they compile and generate correct code.
@feature
Until now, the functions giving access to class information were taking
the class name as parameter.
Except the fact that we needed to search into a hash table for the internal
class structure, no flexibility is possible.
This change consists in modifying most of the APIs using the class name
with a new Eolian_Class type and adapt the code of the C and C++
generators accordingly.
It includes parser updates, database fill and tests on basic and complex
types.
One can define types in this way:
type Evas_Coord: int; /* Simple type definition */
type List_Objects: Eina_List * <Eo *>;
@feature
This patch adds support for protected functions.
In the .eo file, the scope (public by default) has to be added before
the function name e.g:
protected foo ...
To access the protected APIs, #define (CLASS)_PROTECTED is needed e.g:
#define ELM_BUTTON_PROTECTED
When a property needs be defined as virtual pure, its type could not be
given.
It means that, even it was explicit that e.g only the get property if
virtual pure, both (set and get) were considered as virtual pure.
@fix
Now, it is possible to assign a default return value for a
method/property.
It will be used in case the function invocation makes issues, e.g eo_do
failing to find the function...
This tag indicates that the ownership of the parameter/return
value changes.
It is needed by generators (C++/LUA...) to determine if it has to be
freed or not, if it can be used as is or need to be copied...
You can add in the .eo file the eo_prefix:... and data:... in case
you want to override respectively the Eo prefix and the data type.
If "data: null" is used, no data type will be added.
