I have been using mp3Tag for years, but I have only just begun using regular expressions, and I am really having problems with them.
I tag my titles in sentence form, which gets complicated when dealing with remixes. Up until now, my solution has always been to add a "Replace" line for each new remixer I come across, meaning my regular action group includes well over 100 lines. I finally discovered REs and this forum a few days ago, and was thrilled when I found a thread with the exact RE I was looking for:
Action type: Replace with regular expression
Regular expression: ^(.*?)((|$)
Replace matches with: $caps3($1)$2
It is perfect, except for one small problem: It doesn't work. At least not for me, it doesn't. The first word after the opening parenthesis remains lowercase, and I don't understand how any of this works well enough to fix it.
Also, is there a way to restrict this change to that it only adds caps to remix information? I haven't gotten far enough with this to see for sure, but I suspect that as is, this RE, should it come across it, would give you something like:
Sweet dreams (are Made Of This) (eric Prydz Mix), or
Get low (dirty Version)
Can I get it to limit the case change to only strings containing words like mix, remix, edit, dub, etc.? I have not updated since version 2.46 out of fear of losing the action group information I've spent compiling (I'm sure there's a way to move an existing action group to a newer build, but I don't know how, and I'd be too afraid of losing everything even if I did know). This seems to be a much, much better way to go, but at the moment, it is adding as many problems as it is solving.
