Negative Values for int64 not working

[dcbo]

When I register the example
parser.registerCommand("test", "sdiu", &cmd_test);
and parse the following Message:
test "Hello World" 13.23 -45 85
I get 45 for the interger instead of -45
Serial.print("int64: "); Serial.println(args[2].asInt64);
gives
int64: 45

It seems that the negative value is parsed, because when i submit a negative value for uint64
test "Hallo Welt" 13.23 -45 -85
then i get the Error;
parse error: invalid uint64_t for arg 4

Same problem.
I fixed it substituing the end of strToInt function

    return digit == -1 ? 0 : position; // ensure that there is at least one digit

with

   if (digit == -1) {
      return 0;
    }
    if (isNegative) {
      *value = -*value;
    }
    return position; // ensure that there is at least one digit

I have the same issue. Would it be possible to merge #7 which, I believe, fixes this. Meanwhile, I jerry-rigged the code with the suggestion from @m-marini (thanks for that!).

Thank you!

My fix was to:

else if (base >= 16 && 'A' <= buf[position] && buf[position] <= 'F') { digit = (buf[position] - 'A') + 10; } else { if (isNegative) { *value = -(*value); } break; }
