As a follow up: this approach is what we’ve taken with libpd and it’s worked very well so far.
Peter initially discussed with Miller what changes and api access would be needed to wrap libpd. Once those were in place, the rest of libpd is essentially just wrappers around the vanilla core without touching the core directly. All I need to do to update libpd to a newer version of vanilla is to update the pure-data submodule to a new commit/tag and update the makefile to reflect any source file name additions or changes. libpd *is* pd vanilla without the GUI or audio backend, not a variant or custom version. I’m not sure if that has been fully stated on this list. Of course, the api & messaging requirements of libpd are small by comparison to a full UI implementation but I feel a similar process should be possible. -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Oct 7, 2016, at 11:27 AM, Dan Wilcox <[email protected]> wrote: > >> On Oct 6, 2016, at 3:49 AM, [email protected] >> <mailto:[email protected]> wrote: >> >> 1) External developers who want to support purr-data (pd-l2ork) can #ifdef >> their guis. >> 2) For those who don't want to learn a new toolkit, and for unmaintained >> libraries, it'll be up to purr-data developers. >> >> Until we have good documentation for integrating pd+nwjs, the first option >> may only work well for people who have a toe in both pools.
