Class IndentLevels

java.lang.Object

org.ek9lang.compiler.formatter.IndentLevels

All Implemented Interfaces:

Function<org.antlr.v4.runtime.CommonTokenStream, IndentLevels.Levels>

final class IndentLevels
extends Object
implements Function<org.antlr.v4.runtime.CommonTokenStream, IndentLevels.Levels>

THE indent level Pass 1 gives each line - CanonicalIndenter lays the lines out by it, and LineSplitter asks it where a line it makes will be kept, so formatting the result again changes nothing.

A line's level is the number of INDENTs open at its first token. A line whose first token is inside ( [ { is a free-format zone (the lexer gives no INDENT or DEDENT there): Pass 1 keeps its indentation as written. A closing bracket that closes the outermost one is not inside: on its own line it lines up with its statement.
