Hi Ernie,
I immediately saw the problem. You replaced my “GetPOSIXfilePath: method with
the 4D command "Convert path system to POSIX”. You probably did this thinking
“why would Tim do this, 4D already provides a command to do this. I’ll just use
what 4D provides.”
I wrote GetPOSIXfilePath method for the very reason that the 4D command
"Convert path system to POSIX” does not provide a result that you can use with
LAUNCH EXTERNAL PROCESS. Here are some examples with real file paths from my
iMac Pro:
$fileName_t:="Screenshot "+String(Current date;ISO date;Current time)+".png"
$fileName_t:=Replace string($fileName_t;"/";"-") // replace slashes with
dashes in file name
$fileName_t:=Replace string($fileName_t;":";".") // replace colons with
periods in file name
$filePath_t:=Temporary folder+$fileName_t
$filePath_t =
Roadrunner:private:var:folders:27:4_88976133nc2kr57yfc0v4r0000gn:T:Cleanup At
Startup:Screenshot 2018-01-26T14.14.12.png
$myPOSIXFilePath_t:=GetPOSIXfilePath ($filePath_t)
$myPOSIXFilePath_t =
/private/var/folders/27/4_88976133nc2kr57yfc0v4r0000gn/T/Cleanup\ At\
Startup/Screenshot\ 2018-01-26T14.14.12.png
$4DPOSIXFilePath_t:=Convert path system to POSIX($filePath_t)
$4DPOSIXFilePath_t =
/private/var/folders/27/4_88976133nc2kr57yfc0v4r0000gn/T/Cleanup At
Startup/Screenshot 2018-01-26T14.14.12.png
Notice the difference between $myPOSIXFilePath_t and $4DPOSIXFilePath_t. The
space characters are escaped so that the macOS Terminal can handle them. Here
is the code for GetPOSIXfilePath.
// ===========================================
// PROJECT METHOD: GetPOSIXfilePath
// PARAMETERS: $0 = POSIX file path
// $1 = MacOS file path
// DESCRIPTION: Converts a Mac OS X file path to a POSIX path
// with spaces escaped.

C_TEXT($0;$POSIXfilePath_t)
C_TEXT($1;$filePath_t)
$filePath_t:=$1
$POSIXfilePath_t:=Convert path system to POSIX($filePath_t)
// escape spaces
$POSIXfilePath_t:=Replace string($POSIXfilePath_t;" ";"\\ ")
$0:=$POSIXfilePath_t
