Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: wishlist Status: Open Resolution: None Priority: 5 Submitted By: IOhannes m zmölnig (zmoelnig) Assigned to: Miller Puckette (millerpuckette) Summary: $@ and $# expansion (argc, argv)

Initial Comment: the attached patch extends the $-expansion mechanism:

$# expands to the number of arguments; usable both as A_DOLLAR (just "$#") and A_DOLLSYM ("$#-bla")

$@ expands to the entire list of arguments (e.g. [$@ $@( will expand [1 2 3( to [1 2 3 1 2 3(); this is only usable as A_DOLLAR; i.e. [symbol $@-a( will always expand to "$@-a"

why: well, its a way to deal with dynamic length lists that is still missing in pd (though 1st steps have been made with [list])

caveats: what is still missing is an expansion for the selector of messages and objects (the selector of an object would be the object's instantation name); would $$ be a good name for this? (since $0 is already taken)
