Interface cleanup so the report_* family matches the typo-safe ethos of eq.names instead of leaking raw protobuf errors on a misspelled value. - Milestone / ModuleState / JobState: importable str-enums (member == its wire name, so plain strings still work) — autocomplete + a typo-checked happy path. The clean rule: equipment-specific *names* live on eq.names; fixed protocol *value-sets* are enums. - _enum_value(): resolves an enum-or-string arg client-side and, on a bad value, raises ValueError with a close-match hint *before* the wire. Wired into report_job / report_substrate / report_module / request_control_state (all previously raised a raw protobuf ValueError). - Equipment is now a context manager (with Equipment(...) as eq: ...). - examples/wafer_tool.py: a cluster tool tracking one wafer through one module end-to-end (E90 + E157), showing the enums + context manager. - tests/test_enums.py: asserts the enums stay in lockstep with the proto and that the typo path is helpful. Wired into run_interop.sh (pyclient step). - Interop drives both the enum and string forms on the wire + the ValueError typo path. Docs (ch16/ch42) updated; names-vs-enums rule documented. All Python unit tests + 25 pyclient interop checks pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
secsgem-client
A complete GEM tool integration in plain Python. The
secs_gemd daemon owns everything SEMI —
the HSMS link to the host, the GEM state machines, formats, timers,
spooling; this client tells it about your tool and reacts to the host.
from secsgem_client import Equipment
eq = Equipment("localhost:50051")
eq.set(ChamberPressure=2.5) # host sees it on its next poll
eq.fire("ProcessStarted") # S6F11 to the host, report auto-assembled
eq.alarm("chiller_temp_high") # S5F1 (set), eq.clear(...) for clear
@eq.on("START") # host remote commands -> your function
def start(cmd):
run_recipe(cmd.params.get("PPID"))
eq.fire("ProcessStarted") # the host's real completion signal
eq.listen() # block and dispatch (background=True for a thread)
Names are the ones from your equipment.yaml; values are plain Python
(float, int, bool, str, bytes, lists). Errors raise
SecsGemError with the daemon's explanation ("no variable named ...").
No compiled extension, no SEMI knowledge, no C++ toolchain — pip install
and a running daemon is the whole setup.
