Apple

Safari and other WebKit browsers, Mozilla:

file:///Users/Thomas/Desktop/New Folder/My Test.txt

(shown as file:///Users/Thomas/Desktop/New Folder/My Test.txt in Firefox 3.x)

Internet Explorer, Opera:

file://localhost/Users/Thomas/Desktop/New Folder/My Test.txt

Amaya:

/Users/Thomas/Desktop/New Folder/My Test.txt

TextWrangler:

file:///Macintosh HD/Users/Thomas/Desktop/New Folder/My Test.txt

I used TextWrangler's URL for my last example, obviously AppleScript isn't happy with that.

The second problem is with the identification of the file and its path.

Particularly lovely are Script Editor's result messages:

get POSIX path of file "Macintosh HD:Users:Thomas:Desktop:Test.txt"

--> "/Users/Thomas/Desktop/Test.txt"

get POSIX path of file "Macintosh HD:Users:Thomas:Desktop:Test.txt"

--> error number -1700 from «class posx» of file "Macintosh HD:Users:Thomas:Desktop:Test.txt" to reference

where both requests are inside a "System Events" call, the first from

"file:///Users/Thomas/Desktop/New Folder/My Test.txt"

where the " " may or may not be evaluated by System Events, it seems it rather isn't.

By the way, hovering the mouse pointer over "file" in "POSIX path of file" of the result and error messages above reveals strange differences:

'core'\'getd'{'----':obj '{ 'form':'prop','want':'prop', 'seld':'posx', 'from':'obj '{ 'form':'name', 'want':'file', 'seld':'utxt'("Macintosh HD:Users:Thomas:Desktop:Test.txt"), 'from':'null'0 } }, &'csig':'65536 }

for the successful and

'core'\'getd'{'----':obj '{ 'form':'prop','want':'prop', 'seld':'posx', 'from':'furl'("file:///localhost/Users/Thomas/Desktop/Test.txt") }, &'csig':'65536 }

for the failing command.

This leaves me puzzled:

set myFile to POSIX file "file:///Users/Thomas/Desktop/Test.txt"

log "myFile: " & myFile

--> (*myFile: Macintosh HD:Users:Thomas:Desktop:Test.txt*)

get POSIX path of myFile

How can myFile in the last line have the value "file:///localhost/Users/Thomas/Desktop/Test.txt"?

(By the way, does anybody know a way to copy the Apple Event transcript that shows when hovering over AppleScript results in AppleScript Editor?)

file:///Macintosh HD is an invalid path. In POSIX/URL land, the boot volume's name is nowhere to be seen; POSIX file "/" and POSIX file "file:///" both refer to HFS file "Macintosh HD:" (or whatever your boot volume's name is).

OMM (10.6.3), the indirect version with the variable works fine.

Hi Mark,

I don't get your suggestion to work:

tell application "System Events"
try
set myURL to "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"

set myFile to POSIX file myURL

end try
set myFile to POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"

log myFile

get POSIX path of myFile

end tell

results in

tell application "System Events"
get POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
--> error number -1728 from POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
(*file Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt*)
get POSIX path of file "Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt"
--> error number -1700 from «class posx» of file "Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt" to reference

So the first problem is:

System Elends accepts
set myFile to POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"

but not
set myURL to "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"

set myFile to POSIX file myURL

which I find strange.

And then the result of the POSIX file command is
file Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt

which obviously won't word because of the double "Macintosh HD".

Or am I doing it wrong?

Emmanuel's satimage osax solutions work OK, however.

POSIX file works with file URLs; in fact, the class of a POSIX file specifier is «class furl».

POSIX file "file://localhost/Users/richardr/Desktop/bevakad/NORRSÄTRASKOLAN_mall_
A4_2010/"

Should work as-is with System Events; add "as alias" if you intend to use it with the Finder.

satimage osax' absoluteurl command is good at that

and turn that into an alias/ posix file etc.

Preferably in vanilla AppleScript, as shell scripting seems to have some
encoding issues with decomposed/precomposed unicode characters
