@yogi this is very elegant. It won’t replace a proper dump and load, but for that I’d need a lot of discussions with @weefuzzy to see how to change the wrapper to add those mechanisms, to a text object for instance - but for mlp for instance, or knn, where the dumped json is immense, a single line approach wouln’t work and I have tried multi-line in text and it seems to delete them.
Have you give a try the 2 json externals listed on deken in the end? they are only for macos so I feel your pain, but I’ll also write to the pd list about json parsing to structure and text being looked at with pointers - it is a complete brainblowing but some people might have done a native json parsing method with that, i have a hunch it is possible.
in all cases, I’m happy you found a way around. I’d write the file as .json and not .txt but it changes nothing for pd or our objects
