Re: a way to generate python doc strings?

William S Fulton — 2008-12-04T22:12:45

Cheryl Foil started a summer of code 2008 project to extract Doxygen comments from the c/c++ source. The initial target language was for Java. It was enhanced by Jamie Kirkpatrick in September this year for Python. The code lives in the gsoc2008-cherylfoil branch. I'm not sure of the exact status of it, but when it is shown to be polished off, I would like to see it integrated into the main SWIG distribution.

Re: library for csharp

William S Fulton — 2008-12-04T22:23:24

Correct for C#. There is however a c# std_list.i in the patches: https://sourceforge.net/tracker/index.php?func=detail&aid=1375891&group_id=1645&atid=301645 It needs the Examples/test-suite/li_std_vector.i and Examples/test-suite/csharp/li_std_vector_runme.cs to be adapted for std::list, then it can be shipped with the rest of SWIG. Anyone face this problem before? any work around for this? Alternatively, although highly inefficient, create a new interface using std::vector copying the std::list into std::vector and then use std_vector.i to wrap.

Re: %csmethodmodifiers not working

William S Fulton — 2008-12-04T22:15:17

You shouldn't need to put in override manually but should you need to, %csmethodmodifiers needs to come before the class declaration. I think you need to post a cut down version to display your problem because it should just work unless you've done something unusual.

Re: Can an argout typemap be made only apply to functions with no return (void)?

William S Fulton — 2008-12-04T22:14:52

Not possible as the argout typemap works on types and there is no reason why the C++ return type should be related to the C++ inputs. What you could do manually is to modify your typemap to display a warning whenever it is used: %typemap(argout, warning="12345:argout being applied") (const int &a, double &b) { //FINDME } Then you can track down the places it gets used from the generated warnings: example.i:11: Warning(12345): argout being applied example.i:12: Warning(12345): argout being applied Then you can do some manual workarounds like renaming the variables in the method where you don't want it applied. Or if you can't touch the original header files, use %ignore on the methods and %extend to add them back in with different variables names. It is a bit manual, but defining a macro to help will make life easier. Lastly you can control the warning being displayed or not using warning filters using the new warning number '12345', eg run 'swig -w12345' to suppress. William --------------

Re: %csmethodmodifiers not working

Mark Elston — 2008-12-04T19:34:13

Thanks David. It turns out that neither of those options solved the problem but it helped me track it down. I wound up taking a closer look at the generated code for *both* the base and derived classes and found that the return type for this function was *different* in the two classes. The reason was that the header file defining the return type was %include'd *after* the base class header was %include'd but *before* the header for the derived class was %include'd. Once I moved the header file for the return type earlier in the %include list then I got what I expected. In fact, I can remove the %csmethodmodifiers line entirely and it still provides the "override" modifier automatically (as expected).

Re: Bug in SWIG 1.3.35 with std::vector type system?

Ben Webb — 2008-12-04T19:17:15

To summarize for the list: non-const iterators were removed from SWIG 1.3.35 (SVN r10322) to quell some compiler warnings. Since insert() requires a non-const iterator, and begin() now can only return a const one, the code fails. Backing out the patch fixes the problem for me. (Presumably the original warnings will also return, but it seems that warnings are better than non-functional code to me.) Another possible solution is to remove only the const iterators, providing only non-const iterators. That also works for me and presumably would also quell the compiler warnings. It would require the SWIG type system to understand that non-const objects can be cast to const though - I'm hopeful that is already the case.

Re: How can base class pointers to a derived object beusedas a derived object pointer?

David Piepgrass — 2008-12-04T16:37:04

This is a frequently asked question that, unfortunately, doesn't have an easy answer. How SWIG works is that for each C/C++ struct/class there is a corresponding class in the target language. When a C++ function returns a reference or pointer to an object, SWIG creates a new object in the target language to wrap around that object. For example, SWIG's wrapper for your function PolygonDef * PolygonDef::find() will create a new Ruby PolygonDef object. SWIG does not know that find() may return a derived class, it only knows the declared type, so that is the kind of wrapper it creates. I use SWIG for C# and had to go to a lot of trouble to work around this problem. This involved a bunch of typemaps and code that manually examines the object (using dynamic_cast) to find out what kind of object it is on the C++ side; When I find out the actual object type, I translate it to a integer value which is then passed to the C# side. On the C# side I have a big switch statement to choose which kind of wrapper to create

2008/12/4 James Masters gmail.com>: "The following C++ code works as expected" Lets deal with the C++ code on display here then. 1) you can not cast from a pointer to a reference to constant. 2) you are playing with fire casting down the hierarchy without using a dynamic_cast. 3)2 becomes worst when there are more classes in the hierarchy and when the base class is not abstract. You do state "which returns a RectDef object in this case" 4)doing 2 with a C style cast is asking for trouble. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

%csmethodmodifiers not working

Mark Elston — 2008-12-04T01:43:14

I have a class that inherits from a base class. Both classes have a "getType" method (defined as virtual in the base class). I have added the following line to my SWIG interface file: %csmethodmodifiers Derived::getType() "override"; where "Derived" is the name of the derived class. However, the generated C#code doesn't apply the "override" to the getType method of the derived class. Whether the above line is present or not the results are identical. Is there some way to get the override to work for C#?
