name collisions are real: I've once had to debug a Pd patch by a friend of mine and it turned out the problem was that he used cyclone's [gate] object. unfortunately, [gate] is also part of iemlib and it works the other way round! he later added iemlib and now the "wrong" [gate] object was being used, messing up the whole patch in weird ways :-) he could have written [cyclone/gate] to force the cyclone version, but it's not possible to force the iemlib version because it's not a single-object-binary. note that calling the namespace version will also register itself by the classname and therefore override existing classes (without namespace): 1) load iemlib and create [gate] -> iem version 2) create [cyclone/gate] -> cyclone version (obviously) 3) create another [gate] -> cyclone version this wouldn't be a problem if iemlib would be a single-object-per-binary library or offer namespaced creators like [iemlib/gate]. but I'm wondering if loading a lib could automatically "append" the library name to the individual objects. currently, class_new automatically registers 'class_loadsym' (a symbol containing the name under which the object has been invoked) as an additional creator, but only if the last part matches the classname (e.g. "cyclone/gate" <-> "gate"). now if 'class_loadsym' *doesn't* match the classname we can assume that it's the name of a multi-object-per-binary library, prepend it to the classname and register that as an alternative creator. this means that when 'gate_setup' is called as a consequence of 'iemlib_setup', it will register as "gate" and "iemlib/gate", assuming that iemlib was loaded with [declare -lib iemlib]. note that I'm talking about the new version of iemlib, it gets quite awkward for the old one which is split between iemlib1 and iemlib2... one question is how [declare -lib some/folder/iemlib] should be handled: register as "some/folder/iemlib/gate" or "iemlib/gate" or both (besides "gate" of course)? I might try this out and make a PR if it seems to work as I'm imagining it. Christof Gesendet: Samstag, 11.

But we've dealt with this in cyclone. You can, for instance, call [cyclone/>~] and avoid clashing with zexy's - the way this is done is a bit hacky, of course... but simple, just add a new class creator https://github.com/porres/pd-cyclone/blob/master/cyclone_objects/binaries/cyclone_lib.c#L748 Em sáb, 11 de mai de 2019 às 18:17, Alexandre Torres Porres <por...@gmail.com[mailto:por...@gmail.com]> escreveu: Em sáb, 11 de mai de 2019 às 17:26, katja <katjavet...@gmail.com[mailto:katjavet...@gmail.com]> escreveu:On 5/11/19, Jonathan Wilkes via Pd-list <pd-list@lists.iem.at[mailto:pd-list@lists.iem.at]> wrote: [...] > 1.

Is it the case that Pd can have classes like [cyclone/svf~] and [bsaylor/svf~] loaded simultaneously? sure!_______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list[https://lists.puredata.info/listinfo/pd-list] _______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
