I'm not quite sure what you mean, but definitely +1 for a regex version of Replace. Where else do you imagine it being used?
I tried to describe it briefly, and it seemed so clear in my own head ;-)
I am asking for it, specifically because I am currently running into some problems deriving 'Work, Parts, Acts, etc. from the titles of classical tracks.
http://getmusicbee.com/forum/index.php?topic=20209.msg123553#msg123553For this I am making use of the delimiters
, : - such a title should contain for this purpose.
My current virtual formulas seem to work quite well if these delimiters are present and occur not more than once each.
But as soon as a title contains more than one of those delimiters (such as in names, or longer and/or more refined or complicated names or sub-titles etc.) my formulas get confused rather easily.
I think it would be easier to tackle that problem using regex.
And it would probably also be easier to leave out parts of information from the title (or any other tag) that you don't want ending up in the virtual tag.
With the current options, you'll sort of have to reverse your thinking into: "to get the required output, what do I need to leave out first, what do I need to leave out next, what next, repeat, until you finally end up with the part you do want to end up with.
This also requires lots of nested commands, which tend to quickly fry my brain.
With regex the thought-process would be more humanoid-logical for this: "what do I want to have displayed?".
And finally, such a regex can very easily be tested on it's working by means of a regex tester. You will immediately and conveniently be able to see the result of anything you do with a regex.
The way of experimenting with formulas within MusicBee is no fun. As soon a you make the tiniest mistake in a formula, the tag panel will only say something like 'cannot parse', and you won't be able to see results that easy.
