How to disable significant indentation in Scala

.scalafmt.conf

runner.dialect = scala3
runner.dialectOverride.allowSignificantIndentation = false
# allows `if x then y`
runner.dialectOverride.allowQuietSyntax = true

build.sbt

// in sbt
scalacOptions += "-no-indent"

// in scala-cli
//> using option -no-indent

// in mill
def scalacOptions = Seq("-no-indent")

// if you already have indented code and want to make it braceful, use these instead:

// in sbt
scalacOptions ++= Seq("-no-indent", "-rewrite")

// in scala-cli
//> using options -no-indent -rewrite

// in mill
def scalacOptions = Seq("-no-indent", "-rewrite")
