This a Gnome VFS module written in python that lets you browse python modules and objects. How to test: ------------ cp pyfs.conf ~/.gnome2/vfs/modules/ export PYTHONPATH=$(pwd):$PYTHONPATH mkdir /tmp/testing export TMPDIR=/tmp/testing nautilus --no-desktop pyfs:/// You will be presented with a list of modules and you can navigate modules/objects. Notice that only currently imported modules appear initially, but if you hit Ctr-L you can force browsing of particular modules by entering pyfs:///<module> as URL. For example, pyfs:///gtk/gdk will let you browse the module gtk.gdk. How does GnomeVFS decide to use your module: -------------------------------------------- Suppose you want to register some code to handle 'pyfs://'. You put "pyfs: pythonmethod" in a gnome-vfs configuration file[1]. Therefore, when a pyfs:// URI is requested, gnome-vfs loads libpythonmethod.so, which receives the 'pyfs' method name and then tries to import the python module 'pyfs'. The standard python path, plus $(libdir)/gnome-vfs-2.0/modules, is searched for the module. In this module, it looks for a class called 'pyfs_method'. It then creates a new instance of this class, and tries to get the vfs_xxxx methods, which are then used to implement the VFS operations. Caveat: currently the class has to be an old-style class, so don't subclass object. [1] As you are asked to do in the "How to test" section; but notice that to install it system-wide you have to copy the file to /etc/gnome-vfs-2.0/modules/ instead of ~/.gnome2/vfs/modules/.
