moraine-cli (PyPI distribution)

This directory packages the Moraine CLI binaries as platform-tagged Python wheels so they can be installed with:

uv tool install moraine-cli
# or
uvx --from moraine-cli moraine --help

The PyPI distribution name is moraine-cli because the shorter moraine is already taken on PyPI by an unrelated InSAR postprocessing tool. The command-line entry points installed by the wheel are the original short names — moraine, moraine-ingest, moraine-monitor, moraine-mcp — so after uv tool install moraine-cli you still run moraine up the same as before.

The wheel contains prebuilt binaries — the exec-shim package (moraine_cli/__init__.py) calls os.execvpe into the bundled moraine, moraine-ingest, moraine-monitor, and moraine-mcp binaries with the bundled web/monitor/dist/ and config/moraine.toml paths exposed via MORAINE_MONITOR_DIST / MORAINE_DEFAULT_CONFIG env vars.

This is a packaging wrapper, not a Python library. It is not the pyo3 binding at bindings/python/moraine_conversations/ — that ships separately.

How wheels are built

Wheels are not produced by maturin, setuptools, or a direct pip wheel . — they are assembled from the already-built moraine-bundle-<target>.tar.gz release artifacts by scripts/build-python-wheels.py.

This keeps the Rust build and the Python packaging cleanly separated and guarantees the wheel contents are byte-identical to the GitHub Releases bundle.

See RFC #219 for the full rationale.

Why building from source is refused

Moraine needs a Rust toolchain and bun to produce the monitor frontend — way out of scope for pip install. The sdist is a stub that raises a clear error:

$ pip install moraine-cli --no-binary moraine-cli
ERROR: moraine ships as prebuilt binary wheels only. Install via a
       platform with a published wheel, or build from source with:
       https://github.com/eric-tramel/moraine#install-from-source

See scripts/build-python-sdist.py.

Install from the main repo

If you want the full source workflow (editable installs, Rust toolchain, development ClickHouse), see the top-level README instead.
