[cdt-patch] revised class wizard patch
|
Here is the latest revised class wizard patch which fixes the no classes
problem and the base class inclusion problem.
Strategy for resolving the #include "path/to/base_class.h" is now:
(1) Check against known include paths for the project, and if found,
compute the path relative to the longest matching prefix. (Also, use
angle brackets < > if the include path is outside the project).
e.g. (a) Creating class NewClass as a subclass of ExternalClass in
"{workspace}/my_project", where ExternalClass is found in
"/usr/include/ExternalClass.h" and the my_project properties has
"/usr/include" listed as an include directory.
The generated header file would be "{workspace}/my_project/NewClass.h" :
#include <ExternalClass.h>
class NewClass : public ExternalClass
{
....
};
e.g. (b) Creating class NewClass as a subclass of ExternalClass in
"{workspace}/my_project", where ExternalClass is found in
"/usr/include/blah/ExternalClass.h" and the my_project properties has
"/usr/include" listed as an include directory.
The generated header file would be "{workspace}/my_project/NewClass.h" :
#include <blah/ExternalClass.h>
class NewClass : public ExternalClass
{
....
};
(2) Check if the base class is in the same project as the newly created
class. If so, compute the path relative to the newly created header file.
e.g. (a) Creating class NewClass as a subclass of OldClass in
"{workspace}/my_project", where OldClass is found in
"{workspace}/my_project/OldClass.h".
The generated header file would be "{workspace}/my_project/NewClass.h" :
#include "OldClass.h"
class NewClass : public OldClass
{
....
};
e.g. (b) Creating class NewClass as a subclass of OldClass in
"{workspace}/my_project/source", where OldClass is found in
"{workspace}/my_project/headers/OldClass.h".
The generated header file would be
"{workspace}/my_project/source/NewClass.h" :
#include "../headers/OldClass.h"
class NewClass : public OldClass
{
....
};
(3) Fall back to the absolute path.
e.g. Creating class NewClass as a subclass of ExternalClass in
"{workspace}/my_project", where ExternalClass is found in
"/some/path/to/ExternalClass.h".
The generated header file would be "{workspace}/my_project/NewClass.h" :
#include "/some/path/to/ExternalClass.h"
class NewClass : public ExternalClass
{
....
};
The problem with strategy (2) above is the case (b) where you have
relative include paths. What happens if you move a header file in your
project? Right now this breaks your build since it's no longer able to
locate the include.
Ideally, renaming a source or header file should automatically update
all the #include references appropriately. This needs to be done as
part of the refactoring feature.
Longer term, I think a better solution is, if the include path doesn't
already exist, prompt the user and ask if they want to add it to their
project properties. Alain promises that IScannerInfo will eventually
allow setting of include paths. :)
