Typedef word was not generated for enums. Camel case was not respected
for type definition.
Tests have been updated to check enums generation.
@fix T2400
Local and base class functions are supported.
When @empty is provided, dummy functions (initializing the parameters with default
values if needed) are generated.
When @auto is provided on properties, access to internal data variables is done. On
set, it will assign parameters values to private data members. On get,
parameters are set with private data members values.
See the supplied tests as examples.
@feature
As the implements list will soon contain all methods and properties,
do some preparations. The Eolian library now fills in class field in
implements early on when the implement is local. The Eolian C generator
now checks for local implements and skips them (so that things don't break).
This is needed when get properties or methods have to return a
value in case of failure or to initialize parameters.
The way used is to generate an intermediate function that will
initialize the parameters and then invoke the "user" function.
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.
This change adds a new API to retrieve the legacy prefix for enum members
and also adds support for generating enums into the C generator. Besides that,
it prevents generation of entire struct contents when the .eo file declares
a named struct inside of a typedef - as the struct itself gets generated later on.
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.
so the test suites were useless because they didn't ecompile what was
generated. it was missing a ) at the end of calling eo_do_super to
start with. it was missing a call to do_uper fo destructors too. also
it didnt deal with the #include "blah.eo.c" at the file end either so
it produced uncompilable src at the start. again - also fix. this also
fixes test case comparisons to match the now correct generation that
compiles.
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
.eot files are similar to .eo, but they can't contain classes; all .eot files found in include paths
are parsed and information is added into the database. They're there for typedefs and eventually also
enums, structs and constants.
@feature
This patch:
- removes the @def from Doxygen, as it is not correct for API
functions.
- fixes the generation of class comments. When no class description is
supplied, no comment should be added.
place.
Instead of having the calculation (class name + function name + set/get)
in many places in the code, it is now in one place and accessible via a
function environment structure.
In this case, the section 'implements' contains bad information about the
function to override. If the first (at least) function is correct, it
will never fail but use the last correct information retrieved from the
database.
The patch fixes it by checking the result of the database function
eolian_implement_information_get.
@fix
The function eolian_implement_information_get was returning strings for
the class and the function. It was written in this way at the beginning
because it was not needed to verify the correctness of the class and
the function.
Now that we have the namespace feature, this function must check it,
meaning that the class and the function are now known.
So we can return them instead of returning the strings.
The generators had to find the class from the classname. It is no more
needed.
The C++ generator has been adapted to this new API.
To reduce the invocations to strings conversions, we store the
classname, the Eo prefix in upper and lower cases in global variables.
The problem comes when we have to handle overriding functions. A lot of
conflicts between class base and class inheriting can happen.
The chosen solution is to create independent environments storing the
converted strings.
When using -O2 or -O3, the Eina_Bool legacy_support (unsigned char) was
overriding the int eo_needed.
The result was a failure during options check:
Eo flag is not specified (use --eo). Aborting eo generation.
@fix
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.
By using -gi option, the generator appends the functions that are
present into the given eo file and missing into the developer file
(given via -o option as an in/out file).
@feature
Before this change, all the .eo files of the directories given with -I
option were parsed. Most of this information was not necessary at all,
since only the classes belonging to the inheritance of the class given
as parameter were needed.
Now, during the parsing of the given class, the inherits classes are
searched and parsed.
A condition is needed to make it work well. To find a filename for a
class, we consider the lowercase of the class name as the filename we
have to parse.
e.g, Elm_Button -> elm_button -> elm_button.eo
It considerably reduces the generation time.
A fix in the tests was needed.
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
For new classes that don't need legacy, instead of setting legacy null
for all the functions, legacy_prefix can be set to "null" to not
generate legacy.
However, if, for example, only one function among 50 need legacy, you
can specify it by setting for this function the legacy token.
For get properties, if only one parameter is given, the generator sets this one as return type.
There are cases where this parameter must stay a parameter (legacy API).
For example, elm_thumb_compress_get must be like:
void elm_thumb_compress_get(const Eo *obj, int *compress).
Eolian was generating the function as:
int elm_thumb_compress_get(const Eo *obj);
By setting "return void;" in the .eo file, you force the function to
return void.
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
This step is needed to clean the code and to prepare the integration of
Eo2 inside Eolian.
Except the eo_do invocation, there is no reason why legacy has to know
about Eo.
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...
Before eo_do invocation, generated legacy functions returning a value
initialize it to 0.
This change is needed in the case that eo_do fails to find some
function, which leads to an unitialized value and behavior.
When a parameter of a property is const for get but not for set, the
.eo file indicates it by setting a flag 'const' for this parameter.
The generation was checking this flag for C files generation but not for
H files.
- Remove space between type and variable if a star is present.
- Initialize return value to NULL before eo_do. It is needed in case the
eo_do invocation fails (NULL object...).
- Add const to the internal return value if needed.
When an Eo operation returns a value, this one is stored in the last
parameter as an out parameter.
In case the caller doesn't set a pointer there, the storing will be done
in a NULL pointer and will bring to a segfault.
The generator has been modified to handle this case. Now, if the ret
pointer is NULL, the value will not be returned.
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.
When legacy is specified in the .eo file, the generator was adding the
property/method name after the legacy name.
So if you have 'legacy evas_object_textblock_clear_all' for clear method,
it was adding the function evas_object_textblock_clear_all_clear.
- Added Doxygen description to parameters and return
- Added default description for parameters
- Return type needs to be after all the other parameters
- Better handling of stars for pointers: try to figure if a space is
needed between the type and the variable (e.g int *a / int a)
1) Include files now have include guards
2) --gh option generates legacy header with --legacy flag and eo header
without --legacy flag
3) EOLIAN keyword is introduced to mark functions used by generated
file.
4) * for comments when comment text is empty
Now --gh/--gc don't require an additional argument.
If eolian_gen is called with --gc and some file.eo, the tool will
generate file.eo.c.
You can force another filename by using the -o with an argument.
Moreover, logging has been added to the generator.
