| Summary | 0000101: Add a message property @sizetype() to msgc to specify to specify the type of the array size variable | ||||||||
| Description | Currently msgc stores the size of an array in an "int". In OverSim we use msgc generated messages also for real world communication by serializing them with parsim pack()/unpack() methods. In this case using a 32 bit integer is a waste of network communication bandwidth, if we know that an array will only contain a few elements. I've made a small patch to msgc to support the @sizetype property to specify the C++ type of the array size variable. Example: packet BaseRpcMessage { unsigned int nonce; NodeHandle srcNode; AuthBlock authBlock[] @sizetype(uint8_t); } | ||||||||

The above patch seems to break neddoc generation. For all messages which appear after a message with the new @sizetype property in the same .msg file, there is no neddoc generated. BTW, I don't see any error messages or warnings (e.g. undocumented parameters) in the IDE when trying to generate neddoc. Is this not available or is it simply hidden in some place? |

Implemented @sizetype() for array parameters. Unlike in the attached patch, the specified type is also used in the signatures of the field getter/setter methods (as index), and as return type and arg type in the array size getter/setter methods. The IDE neddoc error seems to have been fixed since 4.0, as I could not reproduce it. Documentation from types containing @sizetype was correctly generated. |

Update: I could reproduce the neddoc error: it occurred when @sizetype contained a keyword like "int", "short", "unsigned", etc. It was caused by a parse error: the grammar did not allow these keywords in property values. The workaround would have been to put these types in quotes (like this: @sizetype("unsigned char")). I extended the grammar to include these keywords, so it should now work without quotes as well. |
