Getting from the "Works on CPython 3.6+ but is technically non-portable" state to a fully portable correct implementation that ensures a particular key order in the JSON file thus currently requires the following changes:
Nick, it seems like this is more complicated than it needs to be. You can just pass sort_keys=True to json.dump() / json.dumps(). I use it for tests and human-readability all the time.
sort_keys is only equivalent to order preservation if the key order you want *is* alphabetical order. While that's typically a good enough assumption for JSON, it's not the case for things like CSV column order, TOML or ini-file setting order, etc. Cheers, Nick. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia
