format

Returns a formatted string for displaying mixed-format text in the textField property (see dev.sargunv.maplibrecompose.compose.layer.SymbolLayer). The input may contain a string literal or expression, including an image expression.

Example:

format(
  span(
    feature.get("name").asString().substring(0, 1).uppercase(),
    textScale = const(1.5f),
  ),
  span(feature.get("name").asString().substring(1))
)

Capitalizes the first letter of the features' property "name" and formats it to be extra-large, the rest of the name is written normally.
