How to use

Please refer to test cases.

tableToRow converts table DSL to tuple of columns.
It is destructive.

tableToRow {
  "Bob"   `|` 27 `|` Gender.MALE
  "Alice" `|` 34 `|` Gender.FEMALE
  "Alex"  `|`  1 `|` Gender.MALE
}.map { (name: String, age: Int, gender: Gender) -> Person(name, age, gender) }

listOf(
  Person("Bob", 27, Gender.MALE),
  Person("Alice", 34, Gender.FEMALE),
  Person("Alex", 1, Gender.MALE),
)

tableToRowWithName converts table DSL to tuple of columns by name.
It is like Map structure, i.e., you can get value by name.

tableToRowWithName {
  "name"  `|` "age" `|` "gender" // column names are necessary in the first row
  "Bob"   `|`    27 `|` Gender.MALE
  "Alice" `|`    34 `|` Gender.FEMALE
  "Alex"  `|`     1 `|` Gender.MALE
}.map { Person(it["name"], it["age"], it["gender"]) } // get value by column name

listOf(
  Person("Bob", 27, Gender.MALE),
  Person("Alice", 34, Gender.FEMALE),
  Person("Alex", 1, Gender.MALE),
)

You cal use multi-line string instead.
Please note that it is your own responsibility to map string type to appropriate type.

strTableToRow(
  """
    Bob   |  27 | MALE
    Alice |  34 | FEMALE
    Alex  |   1 | MALE
  """.trimIndent()
).map { (name, age, gender) -> Person(name, age.toInt(), Gender.valueOf(gender)) }

strTableToRowWithName(
  """
    name  | age | gender
    Bob   |  27 | MALE
    Alice |  34 | FEMALE
    Alex  |   1 | MALE
  """.trimIndent()
).map { Person(it["name"], it["age"].toInt(), Gender.valueOf(it["gender"])) }
