I see there are objects in the distribution where adding arguments automatically increases the numbers of inlets or outlets.

The question came up in making a patch to remember a series of numbers ['stepmem.pd' which I posted today in 'abstrations'] : How could I generalize this thing so I could just write something like 'stepmem 7' in an object box and get an example with outlets plus storage for a sequence of 7?

[Or would it be simpler to throw everybody into arrays, lists with pointers, etc?]

in abstractions this is very difficult to do, iemguts helps immensely though.
If you know c simply look at the source code to see how they do it and then program an external, it's way easier to make dynamic inlets/outlets
for examples of abstractions with dynamic numbers of outlets and inlets you could check out some objects of mine (below in signature, the github page)
objects there with dynamic outlets: cyclout, pdgate, pdlist-unpack, and percents
my abstraction [selected] also shows which objects are selected, which helps in making these kinds of patches

I used to be able to do c with the wind behind me, but that was back before everything got muggy with ojbects & classes & the like; so far the things about writing externals for pd just confuse me.

So where does one get these iemguts? -- rummaging in iems?

Maybe I can learn to do this stuff in pidgin lua... but so far don't really need the dynamic outlets, just thought it might be a handy thing to know. Well, thanks for attempt!

ya iemguts is included in Pd-extended 0.43, or you could rummage in iems in the source distribution

WOW! sebfumaster, that library of yours is unreal! I just did a search here, and can't find any formal announcement about it...did you make one?

AHHH! and now i see how you nailed that vline~ synth wave so quickly...your modtriangulator~ patch has a lot of that in place already.

some fully cool stuff in here. cheers!

Okay, I'd been looking for an [iemguts] object to put into things, but what we're talking about is a library!

All right, found that -- but what I'm seeing is a collection of objects... some of which look pretty useful

Hey! Yeah, _really_ useful!

Okay, so you're talking about the objects specifically in the iemguts/ directory.... Gotcha, finally.

[Stopped worrying abt my marbles when I realized they'd always been gone] Thanks!

thanks mod! I made a small announcement in abstract~ http://puredata.hurleur.com/sujet-9537-library but it's grown quite a bit since then. I change it really frequently too
