JchuGroupedVisualTransformation
class JchuGroupedVisualTransformation(groupSize: Int = 4, separator: String = "-") : VisualTransformation
Visually separates text into fixed-size groups without changing the source value.
This is useful for codes, identifiers and card-like values where separators should remain presentation-only. Cursor offsets are preserved for separators of any length.
Parameters
groupSize
number of source characters in each group.
separator
text inserted between groups.
