From 54a97e10431c1cdae910d3b37074a63eda7100fc Mon Sep 17 00:00:00 2001 From: Markus Heiser Date: Tue, 25 Nov 2025 12:51:08 +0100 Subject: [mod] replace js_variable_to_python by js_obj_str_to_python (#2792) (#5477) This patch is based on PR #2792 (old PR from 2023) - js_obj_str_to_python handle more cases - bring tests from chompjs .. - comment out tests do not pass The tests from chompjs give some overview of what is not implemented.
