outText function

void outText(TagContext tc, String text, [ int? line ])

Output the given text to the generated Dart file. It will generate something like the following to the Dart file:

response.write("$text");

Of course, it will escape the text properly if necessary.

Implementation

void outText(TagContext tc, String text, [int? line]) {
  if (text.isEmpty)
    return; //nothing to do

  tc.write('\n${tc.pre}response.write("""');

  for (int i = 0, len = text.length; i < len; ++i) {
    final cc = text.codeUnitAt(i);
    if (i == 0 && cc == $lf) {
      tc.write('\n'); //first linefeed is ignored, so we have add one more
    } else if (cc == $double_quote) {
      if (i == len - 1) { //end with "
        tc.write('\\');
      } else if (i + 2 < len && text.codeUnitAt(i + 1) == $double_quote
      && text.codeUnitAt(i + 2) == $double_quote) {
        tc.write('""\\');
        i += 2;
      }
    } else if (cc == $backslash || cc == $$) {
      tc.write('\\');
    }
    tc.writeCharCode(cc);
  }

  tc.writeln('""");${tc.getLineNumberComment(line)}');
}
