Modified tags are moved within tag files after any change

[pturmel]

Longstanding gripe. JSON is not specified to use ordering of any kind, so all of the common tooling produces non-deterministic output.

Script JSON Format

I do think IA should route all JSONification through instances of TreeMap with a human- and source-control-friendly case-sensitive alphanumeric comparator for the keys. Perhaps with an performance exception for payloads going straight to the browser. Especially including system.util.jsonEncode(). So that all json that ends up on disk (including json from document or other tags) is deterministic. The JSON spec may not care about key order, but lots of other dependent functionality does.

Json Diffing Discussion

FWIW, I made a script recently that achieves this with JSON tag exports, and could be tweaked for many other cases (currently uses the "name" key for sorting lists of dictionaries). # Functions designed to be called via objectScript() in UI expressions. from java.io import File from java.lang import System, Throwable from java.util import TreeMap from com.inductiveautomation.ignition.common.util import Comparators logger = system.util.getLogger(system.util.getProjectName() + '.' + system.ref…

JSON is not compatible with source control/diff without deliberate effort, that IA is failing at.
