Hello,

Did anything ever come from the suggestion (back to the end of 2011) of adding regular expressions to Carnac?

I ask since I have a directory structure, for a subset of my classical music, that has files in varying depths of directories, but I'd like to extract the Composer name from the "top-most" directory.

Files generally reside in a structure like the following:

Opera\<Composer>\<File>

but there are times that an additional directory gets added to the path:

Opera\<Composer>\<Collection name>\<File>

and I would still like to extract the Composer properly.  The filenames also often have a Conductor present, parenthetically, after the name of the work.  It would be nice to be able to extract that field as well.

Any suggestions?

Thanks!
  Matt

Reading through older forum posts, I came across a tidbit I didn't realize -- namely that one can enter an expression when editing Tags!!

Using the expression

=regex(FilePath(), /#Opera\\([^\\]*)#/, 1)

gets Composer filled in correctly for all files!  Based on directory structure, I've always populated opera and other classical music into an F:\Opera directory.  The regular expression above picks off the first-level directory name.

(Carnac's templates, FWIW, appear to be anchored at the end of the filename.  So, it wasn't handling the varying directory depth present within a given composer's folder.)

One of the things that makes MC such a great tag editor is that it processes expressions right in the Tagging Window.  It's very, very powerful as you have just found out.
