[Kde-bindings] Kde-bindings Digest, Vol 123, Issue 4

Thu Jul 11 10:41:04 UTC 2013

    Hello, Cvetoslav,

    Thank you for your offer. First of all, you should read at least some of the SWIG docs - mostly basics and C#-specifics. Second of all, I should tell you a little about the specific case of SWIG and Qt. As you know, Qt uses its own C++ dialect that their moc turns into (nasty) standard C++. Because the Qt extensions are not standard, SWIG cannot recognize them and reports errors. As you will see in the documentation, SWIG can, using the passed in config files, replace certain symbols with other content so that the result is standard C++. This is the approach to use. The other one would have been to generate the real C++ with moc and run SWIG on that. Well, I tried it but even without trying it was clear it would not work. The problem is that SWIG does not work well with cpp code (considering what a mess C++ as a language is, I don't blame them). There is a note in the docs about that. It works OK with header files but moc, on the other hand,
 generates only cpp. So you can see the only possible path is to change the Qt headersand run SWIG on the result.

    About a repository, I do not have oneyet. What I do have is an incomplete attemptto wrap qobject.h and a plan.
    1. The attempt is a SWIG configuration file (*.i) you can find attached; for now it contains #define-s of specific Qt-macros to nothing so that SWIG would not choke. Of course, not all macros should be thrown awaya like that, for example Q_SIGNAL would be better used to generate C#-events and not just ignored. But until we have a successful compilation we could do like that which leads me to:
    2. My plan:
        1. Successfully compile a wrapper for qobject.h the easiest possible way;

        2. Turn signals into events;
        3. Turn name/setNamepairs into properties (note - not just Qt-properties but all accessor functions);
        4. Create a program that would be passed the include directory of Qt and generate the corresponding SWIG config files for each Qt module and run SWIG on each file;

        5. Turn name functions that are just accessors into read-only properties (this 
is a bit tricky but I have a solution; so if you reach this point mail 
me and I'll help you);
        6. Generate the corresponding C#-comments to the classes and their members by using the Qt docs (again, I have a solution here so mail me if you get this far).

    Of course, at 4 we'd have more manualadjustments, after 6 we'd have testing, etc., but this is basically the way I see it.

    The problem part is, I really do not know when I would be able to get in. This is a whole new project to start from almost scratch, the only pieces that might be reused are those about the read-only properties and the code comments. This requires quite a lot of time. I'll be able to help with separate issues but for now I cannot give any guarantees when I'd be able to work on this myself.
    Nevertheless, I wish you luck and feel free to contact me should you have any questions.

    Best regards,
    Dimitar Dobrev

I'd like to participate and help with SWIG wrapper and Qt5 bindings. Do you have any code repository to have a look and get your code.

Regards.

So, to answer you: take at look at the dates in SMOKE's repository log (git://anongit.kde.org/assemblygen, both master and the branch of v4 where the new version is developed). In particular, there are 4 or 5 bugs in SMOKE that prevent it from wrapping Qt 5, all of which I reported myself more than 3 and a half months ago. Again, as you can see from the dates in the repo, none of them were fixed. I think this answers your question.
