Generated files mixed CRLF and LF on macOS and Linux: most lines were written with AppendLine/Environment.NewLine (LF on Unix), while property, enum member and const lines had a hard-coded "\r\n". Repos with *.ts text eol=crlf in .gitattributes then saw every generated file as modified.

All line breaks are now normalized before the file is written. The default is CRLF, matching what the tool already produced on Windows, so output is identical on every OS. It can be changed with line-endings = "lf" in typecontractor.config or --line-endings lf.

  • Add LineEndings enum (Crlf, Lf) and SetLineEndings on the configuration
  • Normalize output in TypeScriptWriter and ApiClientWriter
  • Add --line-endings option to the tool
  • Document the option in README and CHANGELOG
