If you mean generating the same data structure in the script
itself without using import() then the answer is no (for the
normal releases and dev snapshots), and yes via the features
cooking in
https://github.com/openscad/openscad/pull/4478
And if you mean generating a JSON file, today you can always use echo(),
but you'd have to either cut-and-paste from the GUI or lightly filter
output from the CLI.
With 4478, echo(obj) may come close to emitting JSON text. There are
two reasons why it wouldn't:
- It primarily emits OpenSCAD source, and it's unclear as yet whether
OpenSCAD will look like JSON or not.
- JSON requires that all keys be quoted, and it doesn't quote keys
that OpenSCAD/JavaScript doesn't require be quoted.
Perhaps 4478 should gain a json() function that converts an OpenSCAD
object into JSON text.
