I always use parasite when developing C GTK or Vala GTK apps. Usage is really straight forward (at least with Vala and C):
$ GTK_MODULES=gtkparasite app-binary
But I couldn't find a way to work it out with Go-GTK bindings. Any ideas?
Ok, it didn't worked with https://github.com/mattn/go-gtk package, but turns out it worked as expected with https://github.com/conformal/gotk3:
$ go get -tags gtk_3_10 github.com/conformal/gotk3/gtk
So my advice is, for now, to switch to https://github.com/conformal/gotk3 and skip the others GTK biding packages for Go if you want to use Parasite.
