parse method

GemmaTurn parse(String generated)

Parses one raw generated model turn into prose plus any tool calls.

generated is the text emitted by LlamaCppFlutter.generate for a single model turn — with the stop sequence already stripped, so any <|tool_call>…<tool_call|> blocks are complete. Thinking-channel content is removed. Synthetic sequential FunctionCallContent.callIds are assigned so results can be correlated downstream.

Implementation

GemmaTurn parse(String generated) {
  final cleaned = _stripThinking(generated);
  final calls = <FunctionCallContent>[];
  final text = StringBuffer();
  var cursor = 0;
  while (cursor < cleaned.length) {
    final open = cleaned.indexOf(toolCallOpen, cursor);
    if (open < 0) {
      text.write(cleaned.substring(cursor));
      break;
    }
    text.write(cleaned.substring(cursor, open));
    final close = cleaned.indexOf(toolCallClose, open);
    final bodyEnd = close < 0 ? cleaned.length : close;
    final block = cleaned.substring(open + toolCallOpen.length, bodyEnd);
    final call = _parseCall(block, calls.length);
    if (call != null) {
      calls.add(call);
    }
    cursor = close < 0 ? cleaned.length : close + toolCallClose.length;
  }
  return GemmaTurn(text: text.toString().trim(), calls: calls);
}
