Thanks Al, This works like a charm. I can guarantee that no directories will get through, but as to avoiding HFS, I'm afraid Excel wants it. Now if only there was a way to speed up Macruby's load time. It would be nice if someone forked the project to make Macruby a system service launched at boot, with a persistent heap, ala Maglev.

Hi Bob, If at all possible I'd try and avoid the conversion. If this is not feasible, this could help:

def posix_from_hfs(hfs) url = CFURLCreateWithFileSystemPath(nil, hfs, KCFURLHFSPathStyle, false) # final argument is whether the path is a directory or not url.path end

def hfs_from_posix(posix) url = NSURL.fileURLWithPath posix CFURLCopyFileSystemPath(url, KCFURLHFSPathStyle) end

The first method needs reworking, as it assumes that the HFS path is not a directory. I've only did a very brief test of the above code, but it seems to do the job.

Hello again, Macruby community!

I'm trying to rewrite a program that drives Excel with appscript, and running into the problem of translating back and forth between HFS and POSIX pathnames. The old Appscript module included a MacTypes module, and these two translations were provided.

1. to go from POSIX to HFS:

hfs_pathname = MacTypes::FileURL.path(posix_pathname).hfs_path

2. to make the round trip back to POSIX:

posix_pathname = DefaultCodecs.unpack(DefaultCodecs.pack(hfs_pathname).coerce(KAE::TypeFileURL)).path

Do I need to go to the scripting bridge for this? This is Core Foundation stuff, and I'm totally at sea.

Any help would be greatly appreciated.
