| // Package flagpb defines a flag format for protobuf messages, |
| // implements a parser and a formatter. |
| // |
| // Currently flagpb supports only untyped messages, not proto.Message. |
| // Support for the latter could be added too. |
| // |
| // Syntax |
| // |
| // Flag syntax by example. First line is flagpb, second is jsonpb. |
| // -x=42 -b -s hello |
| // {"x": 42, "b": true, "s": "hello"} |
| // |
| // -m.x 3 -m.s world |
| // {"m": {"x": 3, "s": "world"}} |
| // |
| // -rx 1 -rx 2 |
| // {"rx": [1, 2]} |
| // |
| // -rm.x 1 -rm -rm.x 2 |
| // {"rm": [{"x": 1}, {"x": 2}]} |
| // |
| // where x fields are int32, m are message fields, b are boolean and |
| // s are strings. Fields with "r" prefix are repeated. |
| // |
| // Bytes field values are decoded from hex, e.g. "FF02AB". |
| // |
| // Enum field values can be specified by enum member name or number. |
