Re: [Libguestfs] [PATCH] Non-working support for GObject Introspection.

+GObject Introspection bindings +------------------------------ + +Although we add the necessary annotations for GObject Introspection to +the <guestfs*.h> header files, we have not yet had satisfactory +results using them. + +In theory this should allow you to call libguestfs from languages +which we don't yet support, notably Javascript (using GJS or Seed). + +Here is how you can build the GIR bindings. First you have to build +libguestfs normally, then: + + cd gir + g-ir-scanner -n Guestfs --nsversion 0.0 \ + -L ../src/.libs -lguestfs \ + ../src/guestfs.h > Guestfs-0.0.gir + g-ir-compiler Guestfs-0.0.gir > Guestfs-0.0.typelib + +If that went OK, then copy 'Guestfs-0.0.typelib' into the public +directory '/usr/lib{,64}/girepository-1.0/' (or you can make a symlink +which works just as well). + +In theory you should be able to use this immediately from gjs-console: + + LIBGUESTFS_DEBUG=1 gjs-console + gjs> const Guestfs = imports.gi.Guestfs; + gjs> g = Guestfs.create (); + +Currently this gives the following error: + + new guestfs handle 0x2537d00 + Error: No exception was set, but object construction failed somehow + +Because the 'new guestfs handle 0x..' debug message was printed, we +know in fact that construction succeeded! + +It seems we need to "register" the guestfs_h handle with GObject. I +can't get any straight answer to how that would be done.
