From a0a4945d00c0b0b6519427c26a6c0bdf6d839596 Mon Sep 17 00:00:00 2001 From: Karstein Phobic Nyvold Kvistad Date: Sat, 25 Apr 2026 17:06:33 +0200 Subject: [PATCH] fix(install_library_file): add scriptengine.librarymanager to API discovery Empirical finding from this CODESYS install (SP22 Patch 1, ScriptLib 4.1.0.0): the library-management entry point is exposed as 'scriptengine.librarymanager' (single lowercase word). The previously tried paths -- 'libraries', 'Libraries', 'system.libraries', 'library_repository' -- are all absent. Confirmed by dumping sorted([a for a in dir(scriptengine) if not a.startswith('_')]) which lists 'librarymanager' alongside other repository-style modules ('device_repository', 'modulerepository', 'visuelemrepository'). This commit just adds 'librarymanager', 'LibraryManager', and 'library_manager' to the candidate-attribute list at the top of the defensive probe. Existing fallback (iterate .repositories) and method detection (install_library / install / add_library / add) are unchanged and should pick up from there once we know how librarymanager exposes its repositories on this version. Pre-existing diagnostic dump on failure stays in place -- if librarymanager exists but doesn't expose any of the expected install methods, the next failure will print dir(librarymanager) directly so we can iterate again.
