I have to check, but I think 0.8.3 cannot do that, in fact the tsp_ascii_writer and tsp_gdisp do not handle "single element array subscription" but the core TSP do. > With gdisp, I have the same problem (same unreadable graph for symbol_array > or symbol_array[x]). > > The blackboard is created with TSP 0.8.3. > Same probleme with a tsp_bb_provider and consumer from CVS source. This is weird I thought we did at least modify tsp_ascii_writer to handle this particular case. I'll check and keep you informed. May be I'm wrong and/or the tsp_bb_provider does not handle the request properly... The [list of ] "TSP_sample_symbol_info_t" structure found in request sample contains (see tsp_rpc.x): /** * The dimension of the symbol (array size). * <ul> * <li> 1 for scalar </li> * <li> more than 1 for arrays. </li> * </ul> */ unsigned int dimension; /** * The offset of the first requested element * if the symbol is an array. * Only used if dimension > 1. */ unsigned int offset; /** * The number of requested element beginning at offset. * 0 means all element requested beginning at offset. * Only used if dimension > 1. */ unsigned int nelem; which is used to request "partial" values of an array. > Any Idea? Dive into the TSP code (of ascii writer) and look where TSP_consumer_request_sample is called then go back (in the code) where the "TSP_sample_symbol_info_list_t" is built in order to check whether if the appropriate request is built. You may try ascii_writer with an alternate provider (stub, ascii_reader) in order to see if the "unimplemented" feature is on the provider side. -- Erk Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org _______________________________________________ Tsp-devel mailing list Tsp-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/tsp-devel
