val withoutIndent ="""

Below sounds like a bug somewhere as it is not what trimIdent supposed to do.

val sql ="""
    select
        *
    from
        some_table
    where
        id = 100
    order by
        id
    """.trimIndent()
sql

select
*
from
some_table
where
id = 100
order by
id

trimMargin is more flexible and useful than trimIndent.

val withoutMargin1 = """ABC
                |123
                |456""".trimMargin()
withoutMargin1

ABC
123
456

val withoutMargin2 = """
    #XYZ
    #foo
    #bar
""".trimMargin("#")
withoutMargin2

XYZ
foo
bar

val sql ="""

"".isBlank()

"a".isBlank()

false

"a b c".split(" ")

[a, b, c]
