Re: changing part of a string

Huh. For some reason i had it in my head that AS strings were immutable. 

I think Mark is right. This does not work on my mac:

set fullPath to "G5:bigfolder:2 color:myfolder:image1.eps"
set AppleScript's text item delimiters to {":"}
set text item 3 of fullPath to "CMYK images"

This does:

set oldDelims to AppleScript's text item delimiters
set AppleScript's text item delimiters to {":"}
set fullPath to every text item of "G5:bigfolder:2 color:myfolder:image1.eps"
set item 3 of fullPath to "CMYK Images"
set fullPath to fullPath as string
set AppleScript's text item delimiters to oldDelims

So, I checked the code I wrote just days ago. I was under the impression that I had written
set text item n of ... to ...
but I had not. And it does not work.
You DO have to convert the path name to a list; modify the list; then convert back to a full path.

And ... when creating the new full path, you have to qualify each item before adding it to the path name, otherwise, it's just a string that can't be used as an alias. In the example above, the new path is "G5:bigfolder:CMYK images:myfolder:image1.eps", but the folders "CMYK images" and "myfolder" will have to be created if they do not exist. You'll need to move or copy the file "image1.eps".
