If you’ve ever tried googling for help with a Puredata patch, you may have found that it’s not necessarily very effective: you might type in something like ‘pd wire delete’ and get a bunch of results about car wiring.
Two of the best resources today are PDPatchRepo and FLOSSManuals. PDPatchRepo has an extremely helpful forum on which to ask questions and search for answers, as well as a nifty collection of user-submitted patches, externals and abstractions. FLOSSManuals (FLOSS stands for ‘Free-as-in-Libre (freedom) Open-Source Software) has a very useful set of tutorials as well as many lists of objects found in pd-extended.
What we still need, though, is a really good way of finding objects quickly: if I want to take in a list and an index and get out a specific list element, what object(s) can I use? How would I search for that?
