Re: native json parsing

hello,

 [text] object is quite a powerfull tool for building data structures, meanwhile it often need some safe recursive search.

 I'm working on a lua script for experimenting json on pd world if anyone wants to try:

https://github.com/patricecolet/critapec-pd-externals/tree/main/pdjson

It's still experimental, but maybe it could give some clues about sharing json and pd structures.

There are numerous C and C++ libraries which handle the basics and should be leveraged instead of reading bytes with [file] or something similar. Best of all, many of these libraries are only 1-2 files, so making a light wrapper external with minimal requirements for compilation should not be huge issue IMO.

The idea would be to be able to dump fluid* status (mlp for instance) in text, edit, then load them back. This has been seen as useful on other platforms, so I’m trying to find a way…
