🎨 Stylistic: this is a stylistic rule used by the formatting feature.

Enforce spacing inside the square brackets of NBT arrays.

• (object) Root.
  • inside: (number) the number of spaces inside each bracket.
  • zeroValue: (number) Optional. The number of spaces inside each bracket if the NBT array is empty ([X;]). The same number as inside will be used if this is not specified.
  • oneValue: (number) Optional. The number of spaces inside each bracket if the NBT array has exact one value. The same number as inside will be used if this is not specified.
