[PD] create list by header message
Hi, this might be totally simple, but I am wondering what is the most elegant way of creating a list out of individual messages 12 23 34 45 meaning a list which holds four items, and which is always created at the number '12', and sent out at the nu,ner '45', yielding: list 12 23 34 45 so some kind of parallelization depending on a header value (12). thanks for any pointers best, P ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] create list by header message
Do you want every list to have exactly four elements, or do you want '45' to always be the last element? Either way you have two idioms you can use to build the list: 1) [list prepend] with its output feeding back into its right inlet. You collect this into the right inlet of another [list] object, and bang it out when you've got the entire list (and bang the right inlet of [list prepend] to reset it. The benefit is that it's easy to patch; the drawback is that it's slow because you're copying the list twice for each element. 2) message box, using the set, add2, and bang methods. Use set to clear the message box, and add2 $1 to add each incoming float to the message. Then send a bang when you want to output your list. The benefit is that it's fast. The drawback is that if you screw up and build, say, a million element list while the canvas containing the message box is visible Pd, will probably freeze. Then you just need a [moses], [select], or other branching object above one of the two options above to output and reset the list. (Plus a counter if you want four-element lists.) -Jonathan On Thursday, January 23, 2014 1:46 PM, Peter P. p8...@aol.com wrote: Hi, this might be totally simple, but I am wondering what is the most elegant way of creating a list out of individual messages 12 23 34 45 meaning a list which holds four items, and which is always created at the number '12', and sent out at the nu,ner '45', yielding: list 12 23 34 45 so some kind of parallelization depending on a header value (12). thanks for any pointers best, P ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
