Hello

I’ running under 10.11.2

I try to run this simple script :

set theName to "trucmuche"
--set sourcefolder to (path to desktop as text) & "formoosmahna:" as alias
set sourcefolder to choose folder
tell application "System Events"
if not (exists folder theName of sourcefolder) then
make new folder at end of sourcefolder with properties {name:theName}
end if
-- set dest to quoted form of POSIX path of ((sourcefolder as text) & theName)
tell me to set dest to quoted form of POSIX path of ((sourcefolder as text) & theName)
end tell

and I get an awful :

Résultat :
error « Il est impossible d’obtenir POSIX path of \"SSD 500:Users:ME:Desktop:formoosmahna:trucmuche\"." number -1728 from «class posx» of "SSD 500:Users:ME:Desktop:formoosmahna:trucmuche"

Same result if I don’t insert « tell me to ».
I made several attempts and the only one behaving flawlessly is :

set theName to "trucmuche"
--set sourcefolder to (path to desktop as text) & "formoosmahna:" as alias
set sourcefolder to choose folder
tell application "System Events"
if not (exists folder theName of sourcefolder) then
make new folder at end of sourcefolder with properties {name:theName}
end if
set dest to my quoteIt((sourcefolder as text) & theName)
end tell

on quoteIt(aPath)
return quoted form of POSIX path of aPath
end quoteIt

As far as I remember, the initial syntax behaved well in recent past.
Is it a new behavior introduced by 10.11.2 ?

Hello Yvan,

To be honest, this may appear as some kind of relief…

Strictly speaking, "POSIX path" is a property of a file object.
It is defined as such in the dictionaries of Standard Additions and System Events.

Somewhere in the evolution of AppleScript, it became possible to ask for the POSIX path of string (probably thanks to those gratuitous string to file coercions provided by Cocoa).

With interesting (?) results once used and abused as a kind of string to path conversion tool; for example:

POSIX path of "/aaa/bbb/ccc"
—> /aaa/bbb/ccc
POSIX path of "aaa/bbb/ccc"
—> /aaa:bbb:ccc
POSIX path of "aaa/bbb:ccc"
—> /aaa:bbb/ccc

I guess your "workaround", based on the quoteIt() handler, just allows to avoid the more reasonable behavior of System Events.

To be honest too, here is a script with the several attempts I made.

set theName to "trucmuche"
--set sourcefolder to (path to desktop as text) & "formoosmahna:" as alias
set sourcefolder to choose folder
tell application "System Events"
if not (exists folder theName of sourcefolder) then
make new folder at end of sourcefolder with properties {name:theName}
end if

end tell
end tell

on quoteIt(aPath) # Here aPath is a string
return quoted form of POSIX path of aPath
end quoteIt


System Events refuse every attempts to get POSIX path of something.
For my point of view it’s not too surprising and it’s why I used tell me to.
What is puzzling is the fact that even when I use tell me to, set dest to quoted form of Posix path of aString -- which is a correctly formed path - fails too
