Hi everyone,
Just wanted to share some code.
I find it weird that I couldn't find any native function that would return the
position of a element in a list...
Maybe I overlooked something.
But I needed it, so I took the code of Emmanuel Levy and made it a bit more
fail-proof.
(in his code, position of "TT" in list {"TTT"} would give 1, which was not good
to me)
on positionInList(theItem, theList) -- credits Emmanuel Levy
set MARK to "◊" -- of course you won't be able to look for such character's
position in list, so choose one that isn't used
set ASTID to AppleScript's text item delimiters
set AppleScript's text item delimiters to MARK & return & MARK
set theList to MARK & theList & MARK
log theList
try
set theIndex to count paragraphs of text 1 thru (offset of (MARK & theItem &
MARK) in theList) of theList
on error
set theIndex to 0
end try
set AppleScript's text item delimiters to ASTID
return theIndex
end positionInList
set myList to {"TTT", 1, 67, "TT", 8}
my positionInList("TT", myList)
Enjoy !
😊
