Platform-branches the Wine-specific execution so Linux behaves identically
while macOS drives LTspice.app natively. Implemented from muel9560's measured
spec + validated where possible against a Wine -netlist oracle on Linux.
- config.py: get_launch() abstraction (argv prefix + env + path translator);
IS_DARWIN, LTSPICE_BIN (env-overridable), LTSPICE_LIB_ROOT under
~/Library/Application Support/LTspice on macOS. Linux resolves to the
historical Wine paths unchanged.
- runner.py: darwin branch uses the native binary, POSIX paths (no Z: map),
plain -b (never -Run), and completion by polling for a stable .raw (the Mac
GUI app's exit code is unreliable). Linux keeps communicate()+wait_for.
- netlister.py (new): asc_to_netlist() converts a schematic to a netlist on
macOS, since the Mac CLI can't netlist a .asc. Union-find net extraction;
all 15 templates netlist, topology matches the Wine -netlist oracle.
- library_tools.py: check_installation reports platform/binary/lib-root/
version/gui-session on macOS.
- packaging/docs: drop 'Linux only'; document LTSPICE_BIN + GUI-session need.
Adversarial review fixes: restore kill+reap of the Wine subprocess on Linux
timeout (was orphaning the process -- a real regression); alias duplicate net
labels instead of aborting (sallen-key); synthesize NC_xx nodes for floating
pins (op-amps) to match the oracle; use asyncio.get_running_loop().
Linux unaffected: 476 unit + 10 integration (real Wine) still pass; +48 unit
+8 integration for the platform/netlister paths. macOS runtime (LTspice.app
invocation, GUI session, poll timing) needs validation on Kevin's hardware.
Tools organized by category: simulation, waveform extraction,
signal analysis, noise, stability/power, schematic/netlist,
and library/templates. Added resources and prompts tables.
Rename package from mcp-ltspice/mcp_ltspice to mcltspice throughout:
source directory, imports, pyproject.toml, tests, and README.
Remove startup banner prints from main() since FastMCP handles
its own banner and stdout is the MCP JSON-RPC transport.
