Re: Announcing: Perl bindings for LibSoup

The introspection framework really looks nice. Your examples show that
it's very easy to write the bindings for arbitrary C C libraries quite
easily. What's the catch?  ;) Are there bugs or unimplemented parts?
This is too nice to be true.

Well, all this has been cooking for a while: about six years. But there are some rough edges remaining, some in gobject-introspection itself, many in the Perl bindings. Nothing insurmountable though.

This is the future of language bindings (in a GNOME context at least).

Is there a way to provide custom made XS methods to an introspection
perl package? For instance, SoupMessageBody is defined as:

typedef struct {
        const char *data;
        goffset     length;
} SoupMessageBody;

And provides no accessor for data or length. Is there a way to
complete the introspection binding with extra XS methods?
If so do you know of an existing cpan package that does this?

Adding custom XS methods is no problem: just write them as you normally would. But in the case you mention, that's not necessary. gobject-introspection provides the means to get and set public fields of boxed types. I don't remember right now how good the support for that is in the Perl bindings, however.
