[Swig-devel] best way to get from type to feature text?

[David F. <fr...@tu...>]

Hi all,

I haven't played much with %feature, but it looks like it would be
useful for an addition I'd like to make to the perl5 interface
generator.

Suppose that:

   1. a .i file has been read that has a %feature defined like so:

	%feature("myfeature") SomeType %{ text here %}

   2. the functionWrapper() function has been called for some function
      to be wrapped and this function returns a pointer (or reference
      or ... ) to a SomeType

What's the best way to retrieve the text defined within the feature?

For example, suppose I had this:

  virtual int functionWrapper(Node *n) {
    String *name = Getattr(n, "name");
    String *iname = Getattr(n, "sym:name");
    SwigType *d = Getattr(n, "type");

	...

    /* Here's code I want to add ... */
    String * text = GetFeatureText(d, "myfeature");
    if (text) {
      ...
    }

Is there already a function that I can use instead of
GetFeatureText()?  If not, can anyone provide an outline that shows
how this function would work?

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

By the way, what I'm trying to do is augment the perl code that is
generated.  There are any number of typemaps that can manipulate the
C/C++ code that is generated, but very few that augment the perl code
that is generated.  Perhaps I missed something, but there doesn't seem
to be a typemap that is already defined that will handle this.
Perhaps someone knows of one?

Tx.
