Importing actions from Windows

[ohrenkino]

What i said was that the code that you supplied with that hard to read listing does not lead to the expected result of swapping words.

I would use 2 actions of the type "Format value" for the artistsort field:
Format string: $regexp(%artist%,'(.*) (.*) (.*)','$2, $3 $1')
and the next:
Format string: $regexp(%artist%,'(.*?) (.*)','$2, $1')

Edit: why was it necessary to import the actions from Windows as you got a solution for the Mac already:

AlbumArtistSort and ArtistSort - switch first and last names

I had a look at the expression used in #17 and it seems to me that an escape of the opening bracket in the first match group is missing. A correct expression would be ^([^,\[]+)\s([^,\[]+)$ The same applies to the expression using in #18 ^([^,\[]+)\s([^,\[]+)\s(\[.+\])$
