Fwd: [Pyobjc-dev] How do I copy file Metadata ?

[st c. <stc...@gm...>]

Thank you very much. NSFileManager.copyPath did the job.

xattr also is very helpful: My application makes standard html files.
They cannot however be viewed correctly by Safari (etc) because their
links are not local filesystem relative. Therefore I want my
application to set their defaults such that it gets to open the files
it makes, in the same way as "Get Info" in the Finder allows a user to
specify what should open a given file.

I set z.html's default opener to my program, and then used xattr so:

import xattr
z =3D xattr.xattr("z.html")
xattr.setxattr("y.html", 'com.apple.ResourceFork', z['com.apple.ResourceFor=
k'])

and now y.html was also opened. My question is: how do I make the
contents of com.apple.ResourceFork. There seems to be some xml in
there but also a lot of binary. Or is there some other way of doing
this?

Thanks,

Sengan
