parse method

void parse(String sourceCode, { bool replMode = false, })

Implementation

void parse(String sourceCode, {bool replMode = false}) {
  if (replMode) {
    // Check for an incomplete final line by finding the last (non-comment) token.
    final bool isPartial = endsWithLineContinuation(sourceCode);
    if (isPartial) {
      partialInput = '${partialInput ?? ""}${Lexer.trimComment(sourceCode)} ';
      return;
    }
  }
  final Lexer tokens = Lexer('${partialInput ?? ''}$sourceCode');
  partialInput = null;
  _parseMultipleLines(tokens);

  if (!replMode && needMoreInput()) {
    // Whoops, we need more input but we don't have any.  This is an error.
    tokens
        .lineNum++; // (so we report PAST the last line, making it clear this is an EOF problem)
    if (outputStack!.length > 1) {
      throw CompilerException.withLocation(
        errorContext,
        tokens.lineNum,
        "'function' without matching 'end function'",
      );
    }
    _checkForOpenBackpatches(tokens.lineNum);
  }
