From ef42eb60bbd74980b857582edbf73da33ba6fd4a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Noah=20Piqu=C3=A9?= Date: Wed, 15 Apr 2026 16:20:38 +0200 Subject: [PATCH] fix: correct pin location calculation and symbol reference dedup in kicad-skip Three bugs fixed in the schematic component and pin locator pipeline: 1. component_schematic: remove redundant symbol.append() after clone() kicad-skip's clone() already inserts the raw element into the schematic tree. The subsequent NamedCollection.append() detects the reference as already registered (from the elementRename triggered by setting property.Reference.value) and renames it "R1_" with a trailing underscore, causing all subsequent pin lookups to fail. 2. pin_locator: negate lib y coordinate before rotation lib_symbols in .kicad_sch use library y-up convention; schematic coordinates use y-down. get_pin_location now negates pin_rel_y before applying rotation, matching KiCad's own transform order (same approach as _transform_local_point in schematic_analysis.py). 3. pin_locator: add .rstrip("_") guard in all symbol reference lookups Defensive guard against any residual cases where kicad-skip writes a trailing underscore to the Reference property value. Also fixes the self-test script to use template_with_symbols.kicad_sch (which contains placed _TEMPLATE_* symbols) rather than the expanded template (which only contains lib_symbols definitions and has no cloneable instances).
