How to skip whitespace when extracting tags from filenames

Support
1

Hi,

Sorry if this is an obvious question but I've read the FAQ and searched and can't figure this out.

I'm trying to parse tags from filenames / directory hierarchies. Some of the files have the format

%track%-%title%

and some have

%track% - %title%

or other variation of whitespace / no whitespace or even underscores instead of hyphens.

How can I write a Format string that will work for all variations? I'm a software engineer by trade, and I'm not stupid, but the FAQ does not explain how to use $replace scripts at all. It needs some concrete examples.

Thanks,

Alex

Action: Guess Values
Source: $trim($regexp(%filename%,(.*)(-|).,$1))@@@$trim($regexp(%_filename%,.(-|_)(.*),$2))
Formatstring: %track%@@@%title%

here is help for the scripting:
https://docs.mp3tag.de/scripting

and here for the regular expressions:
https://docs.mp3tag.de/actions/replace-regexp

EDIT:
i used %artist% instead of %track% because i was reading your question not good enough.
i fixed that now.

This could work ...

Begin Action Group Test 2011#20110112.Guess

Action #1
Actiontype 7: Import tag fields (guess values)
Source format: $regexp(%_FILENAME%,'^ *(.+?)[ _-]+(.+?) *$','$1---$2')
Guessing pattern: %TRACK%---%TITLE%
End Action Group Test 2011#20110112.Guess (1 Action)

.. and this too ...

Begin Action Group Test 2011#20110112.Guess.2

Action #1
Actiontype 7: Import tag fields (guess values)
Source format: $num(%_FILENAME%,1)---$trimLeft(%FILENAME%,'0123456789 -')
Guessing pattern: %TRACK%---%TITLE%
End Action Group Test 2011#20110112.Guess.2 (1 Action)

.. and this too ...

Begin Action Group Test 2011#20110112.FormatValue

Action #1
Actiontype 5: Format value
Field: TRACK
Formatstring: $num(%_FILENAME%,1)

Action #2
Actiontype 5: Format value
Field: TITLE
Formatstring: $trimLeft(%FILENAME%,'0123456789 -')
End Action Group Test 2011#20110112.FormatValue (2 Actions)
