Have you checked that with the tool GetFileInfo? I get those
reversed types/creators for some files on my PPC machine.
I get the reversed types/creators for *all* files (if they got them at
all) with MacOS.GetCreatorAndType.
Thanks for the GFI hint - that tool gets it right:
hraban$ GetFileInfo MontageA3.pdf
file: "MontageA3.pdf"
type: "PDF "
creator: "CARO"

Seems like some Apps write bogus type/creator fields.
Don't know. Most modern apps don't use type/creator any more at all.
That should read ('FH09', 'EPSF').
I didn't knew endian-ness affects the order of strings.
Very funny! ;-)
It isn't technically a string. More like UInt32. IIRC type/creator
are stored in big-endian order.
Ok, but how can I convert those Ints to string?
I get them as Ints also from UTGetOSTypeFromString:
>>> from LaunchServices import UTGetOSTypeFromString
>>> UTGetOSTypeFromString('public.jpeg')

Anyway, the traditional MacOS type and creator would be a nice
addition. The MacOS module is deprecated. I could ask the Finder
via appscript, but I wonder if there's a more direct way - I'm
surprised the mactypes module's Alias and File classes don't know
type and creator.
There are 2 ways I currently know of:
- via LaunchServices
def get_mac_fileinfo(POSIXPathToFile):
import LaunchServices as LS
return LS.GetInfoForPath( POSIXPathToFile, LS.kLSRequestAllInfo)
AttributeError: 'module' object has no attribute 'GetInfoForPath'
Where did you find that function?
I didn't find it in Apple's whole library.
- via a FSSpec which is deprecated since OS 10.4:
def get_mac_fileinfo(POSIXPathToFile):
import Carbon.File as CF
finfo = CF.FSSpec( POSIXPathToFile ).FSpGetFInfo()
return finfo.Creator, finfo.Type, finfo.Flags, finfo.Fldr,
finfo.Location
The FSRef of doing things would be via FSGetCatalogInfo.
Unfortunately the FSGetCatalogInfo structure omits the finderInfo
field.
That works, but I'd prefer a "future proof" method.
