Class LineSplitter

java.lang.Object
org.ek9lang.compiler.formatter.LineSplitter
final class LineSplitter extends Object
Pass 4 of the EK9 source formatter: Line Splitting.

Parses the source to obtain both a token stream and parse tree, then identifies lines exceeding the maximum length threshold. For each long line, the parse tree determines the construct type and applies the appropriate splitting strategy:

  • Strategy 1: Parameter lists — one argument per line
  • Strategy 2: Stream pipelines — one stage per line
  • Strategy 3: Boolean/logical chains — break after and/or/xor
  • Strategy 4: Long binary expressions — break after operator

Lines inside multi-line comments and string literals are exempt.

      String split(String source)
      Apply line splitting to the given EK9 source.

      Iterates: each pass may split an outer construct, producing new lines that themselves exceed the limit (e.g. nested parameter lists). The loop re-parses after each pass and continues until no further splits are needed or the iteration limit is reached.

      Parameters:
      source - The EK9 source code (already indented, reordered and spaced).
      Returns:
      The source with long lines split, or null if parsing fails.
