add_label bypasses kicad-sch-api serializer entirely — generates
s-expression strings and inserts them directly into the .kicad_sch
file via atomic write. Fixes two upstream bugs: global labels silently
dropped on save (serializer never iterates "global_label" key), and
local labels raising TypeError (parameter signature mismatch in
LabelCollection.add()).
add_power_symbol now falls back to sexp pin parsing when the API
returns None for custom library symbols (e.g. SMF5.0CA). Extracts
shared resolve_pin_position() utility used by both add_power_symbol
and batch operations.
Batch labels also fixed — collected as sexp strings during the batch
loop and inserted after sch.save() so the serializer can't overwrite
them.
Reduce _rc() and transform_pin_to_schematic() rounding from 3 to 2
decimal places to match KiCad's 0.01mm coordinate quantum — prevents
union-find misses when wire endpoints and sexp-parsed pin positions
differ at the sub-quantum level.
Use schematic stem as subdirectory inside .mckicad/ so multi-sheet
analysis outputs (connectivity.json, etc.) don't collide.
_build_connectivity() used sch.list_component_pins() which returns
empty for custom library symbols. Added a second pass that falls back
to parse_lib_symbol_pins() + transform_pin_to_schematic() for any
component that returned 0 pins from the API. This brings custom IC
pins (e.g. ESP32-P4's 105 pins) into the union-find net graph.
kicad-sch-api has two parsing gaps: get_symbol_definition() returns
None for non-standard library prefixes (e.g. Espressif:ESP32-P4),
and there is no sch.global_labels attribute for (global_label ...)
nodes. This adds a focused parser that reads directly from the raw
.kicad_sch file as a fallback, integrated into the connectivity
engine, pin extraction, and label counting tools.
Root cause: kicad-sch-api doesn't back-populate comp.pins or sch.nets
on loaded schematics. All data is accessible through alternative APIs.
Pin extraction: use comp.get_symbol_definition().pins for metadata and
sch.list_component_pins(ref) for schematic-transformed positions.
Connectivity: new wire-walking engine using union-find on coordinates.
Walks wires, pin positions, labels, and power symbols to reconstruct
the net graph. Replaces broken ConnectivityAnalyzer/sch.nets fallbacks.
Eliminates 'unhashable type: Net' crash.
Hierarchy: use sch.sheets.get_sheet_hierarchy() instead of the broken
sheets.data.get("sheet", []) raw dict approach.
Labels: supplement sch.get_statistics() with sch.labels.get_statistics()
and sch.hierarchical_labels for accurate counts.
99 tests passing, lint clean.
New modules:
- patterns/ library: decoupling bank, pull resistor, crystal oscillator
placement with power symbol attachment and grid math helpers
- tools/batch.py: atomic file-based batch operations with dry_run
- tools/power_symbols.py: add_power_symbol with auto #PWR refs
- tools/schematic_patterns.py: MCP wrappers for pattern library
- tools/schematic_edit.py: modify/remove components, title blocks, annotations
- resources/schematic.py: schematic data resources
43 new tests (99 total), lint clean.
config.py evaluates os.environ at import time, but mckicad/__init__.py
eagerly imports config via 'from .config import *'. The old main.py
loaded .env after importing from mckicad, so the search paths were
always empty. Now .env is parsed with stdlib before any mckicad imports.
Also fix start.sh to use 'uv run' instead of stale venv/ path.
