Useful regex formulas

With the change in 3.1 of moving the Musicians Credits into the Artists Splitter, where they are all combined into the Artists: Performer catergory (see post here), I needed a way to only show the entries that were in the "Artist (role/instrument)" format.
This is the virtual tag I used:

Code

$Replace($RxReplace(<Artists: Performer>,"(?:([^;\(]*\([^\)]*\))(?:;|$))|([^;\(\)]+(?:;|$))","$1"),")",");")

The following regexp extracts just the "Producers" from the <Artists: Performer> category and can be used for a virtual tag

Code

$Replace($Trim($RxReplace(<Artists: Performer>,"([^;\(]*\(producer\))|(?:([^;\(]*\([^\)]*\))(?:;|$))|([^;\(\)]+(?:;|$))","$1"))," (producer)","")

or more generally:

Code

$Replace($Trim($RxReplace(<Artists: Perfromer>,"([^;\(]*\(ROLENAME\))|(?:([^;\(]*\([^\)]*\))(?:;|$))|([^;\(\)]+(?:;|$))","$1"))," (ROLENAME)","")

These are two regex formulas to extract performers name & role/instrument name (working for multi-value tags as well) to be used as filtering category.

For <Artists: Performer> tag value

"Paul McCartney (electric bass guitar); Ringo Starr (drums); George Harrison (electric guitar)"

Code

$IsNull(<Artists: Performer>,,$RxReplace(<Artists: Performer>,"([^;\(]*)\([^;\)]*\)","$1"))

returns "Paul McCartney;Ringo Starr;George Harrison"

Code

$IsNull(<Artists: Performer>,,$RxReplace(<Artists: Performer>,"[^;\(]*\(([^;\)]*)\)","$1"))

returns "electric bass guitar;drums;electric guitar"

A regex I use to format titles, especially for audio files with a CUE sheet, where it is not possible to specify <Movement#> and <MovementName> for each track.

Possible title content expected in input:

Title format	Title content	Resulting display
Text	Protector of the Common Folk	Protector of the Common Folk
#. Text or #letter. Text or P#letter. Text	1. Adagio 12c. Chinese dance P3.12. Seid froh dieweil	1. Adagio 12c. Chinese dance P3.12. Seid froh dieweil
(Text) Text	(Encore) Wien, Wien, nur Du allein	(Encore) Wien, Wien, nur Du allein
Number+letter. (Text) Text	4b. (Choir) O Freunde, nicht diese Töne!	4b. (Choir) O Freunde, nicht diese Töne!

Code

{font: Ubuntu;Italic;12}{color: 0,105,155}$RxReplace(<Title>,"^(P?[0-9.]+[a-z]*[.] )?([(][^)]*[)])?(.*)","$1"){color: 20,125,20}$RxReplace(<Title>,"^(P?[0-9.]+[a-z]*[.] )?([(][^)]*[)])?(.*)","$2"){font: default}{color: default}$RxReplace(<Title>,"^(P?[0-9.]+[a-z]*[.] )?([(][^)]*[)])?(.*)","$3")

$RxReplace is called three times, because it is not possible to insert the formatting codes directly into the replacement string.

Adapt to your taste and MB skin:
- {font: Ubuntu;Italic;12} and {font: default}
- {color: r,g,b} and {color: default}
