savelines() new line in file?

[devilsknite1]

PHP Code:

function onActionServerSide( afi, svar1, svar2 ) {
  switch( afi ) {
    case "callTextTypeFile": {
      temp.text_type_file.loadLines( svar1 );
      triggerClient( "gui", name, "displayTextTypeFile", temp.text_type_file );
      break;
    }
    case "editTextTypeFile": {
      temp.text_type_file = { svar1 };
      temp.text_type_file.saveLines( svar2, 0 );
      break;
    }
  }
}

//#CLIENTSIDE

function onActionClientSide( afi, file ) {
  switch( afi ) {
    case "displayTextTypeFile": {
      for ( temp.i : file ) {
        temp.ne @= temp.i @ "\n"; <-- This is the problem
      }
      onEditTextTypeFile( temp.ne );
      break;
    }
  }
}

function onPlayerChats() {
  temp.tokens = player.chat.tokenize();
  if ( player.chat.starts( "/lf " ) ) {
    this.file_selected = temp.tokens[ 1 ];
    triggerServer( "gui", name, "callTextTypeFile", temp.tokens[ 1 ] );
  }
}

function onEditTextTypeFile( svar ) {
  Gui stuff here, removed for space reasons
} 


The problem is not in the GUI or loading the text file, it's the text file itself. \n obviously won't make a new line in the text file, but it will the GUI. How would I go about making a new line, in both, the text file and the GUI?
