agni (Python client)

A typed Python client for agni. It calls the agni CLI or a running agni serve and returns the wire contract's own message classes, generated from protos/agni/v1.

pip install 'agni-eda[xlsx]'           # a release, from PyPI
pip install -e 'clients/python[xlsx]'  # a checkout

The distribution is agni-eda because PyPI's agni is an unrelated project, and the import is agni. Match its version to the agni binary or server it talks to.

from agni import Client, CliTransport, ConnectTransport

c = Client(CliTransport("agni", mounts={"tut": "examples/tutorial-project"}))
# or: c = Client(ConnectTransport("http://127.0.0.1:8080"))
snap = c.ingest("mount://tut/designs/gateway")
resp = c.run_query(snapshot=snap, query='component.class(?c, "resistor") => ?c')
c.delete_snapshot(snap)

Every question names a snapshot, a design loaded once under one config (agni issue 1061). ingest returns its name, and takes the board_uri, as_named and overlay a request used to carry, and flatten_hierarchy, which reads a hierarchical EDIF netlist whole as --flatten-hierarchy does. A server holds a snapshot until it is deleted or evicted, and refuses one whose files changed. The client keeps the definition of each snapshot it ingested, so a question naming one the server lost is asked again after ingesting it under the same name, and one whose files changed after updating it, as the viewer does (agni issue 1067). A snapshot this client did not ingest, or deleted, still raises AgniError with code not_found, and AgniError.snapshot_unavailable says which. The CLI transport has no server, so it keeps each definition itself under a name it mints (snapshots/cli-1) and turns it back into flags for every command it runs.

The guide, docsite/content/build/other-languages.md, covers choosing a transport, which rpcs the CLI covers, where the two differ today, and writing tables to xlsx.

• examples/audit_workbook.py writes a five-sheet audit workbook of the tutorial board, asking its four tables as one query set (run_queries) so the design is read once.
• examples/revision_audit.py compares two revisions of the gateway and audits the newer one, writing a workbook and a markdown summary that lists each tab still to be built. make exercise-revision-audit runs it with the checkout's binary (agni issue 843).
• make proto-py regenerates src/agni/v1. Never edit it by hand; make proto-check fails on drift.
• make python-test runs the suite against a built binary and a real server.
• make python-dist V=vX.Y.Z builds the sdist and wheel a release publishes into dist/python and installs the wheel into a fresh venv to check it. The release workflow runs it, and the gate runs python-dist-check.
