Kotlin Options

The configuration options for Kotlin are listed below.

Collection Type​

Choose the outer collection syntax:

  • array for arrayOf(...)
  • list for listOf(...)

Assign to Variable​

When enabled, output is assigned to a named variable like:

val data = listOf(...)

Use Variable Name to configure the assigned name.

Mutable Assignment​

Choose whether assignment uses:

  • val (default, immutable reference)
  • var (mutable reference)

Number Convert​

When enabled, numeric-looking values are quoted as strings.

When disabled, numeric-looking values are emitted as numeric literals.

Anonymous Objects​

When enabled, each row is output as a map (mapOf(...)).

When disabled, each row is output as an instantiated object, and a data class definition is included.

Use Object Name to configure the class name when anonymous objects are disabled.

Object names are normalized to Kotlin PascalCase for generated data class declarations.

Mutable Collections​

When enabled:

  • row maps are emitted as mutableMapOf(...)
  • outer list collections use mutableListOf(...) when collection type is list

Array collection type remains arrayOf(...).

Pretty Print​

When enabled, output uses line breaks and indentation.

Delimiter​

Choose indentation delimiter:

  • tab
  • space
  • custom value

For custom value, set Custom Delimiter.

Trailing Comma​

Control whether the final row in pretty-printed collections includes a trailing comma.
