I've found a way to do so using this below but how can you simplify it to use the built in merge action.
Does it support linefeeds? I've tried \n and \\u0009 but no success.
Name of action group: Format 1#UNSYNCLYRICS Merge Lines
Action type: Format value
Field: UNSYNCEDLYRICS
Formatstring: $regexp($regexp($meta_sep(unsyncedlyrics,steveheros_sep),steveheros_sep,\n),\beng||,)
EXAMPLE OF THE MESS:
I think that the carriage return, linefeed characters are $char(13) and $char(10). $char(9) is the tab character.
As far as I found it, the action "Merge duplicate fields" takes the contents of the input fields as literals as it does not say "format string".
Thanks.
But. Nope. Both those linefeed chars don't work.
Guess I stumbled upon a solution then.
I'll change the eng bit in the starting post and change it to a regexp to allow for other langs.
