This is for export to a txt file.

The idea is to simply count the number of chars `$len(%genre%)` and trim the corresponding white space chars to the right, so the right border aligns again.

```auto
 ___________________________________________
| Artist: %artist% |
| Genre: Classical -->|

```

```auto
 ___________________________________________
| Artist: %artist% |
| Genre: Classical <--|

```

Can someone help with this function?

Basically, you determine the length of the whole real string and then $repeat() a number of space characters in which you take the total position of the `|` and $sub() the length.

Here is a (German) thread that centers text:

Die Rahmenbreite ist fest vorgegebne (z.B. 65 Zeichen) etwa so: ================================================================================ =..................................mein Album..................................= ================================================================================ (die Punkte links und rech…

The code should be readable, though
