go test ./...

# Build
go build -o onyx-cli .

# Lint
staticcheck ./...

Publishing to PyPI

The CLI is distributed as a Python package via PyPI. The build system uses hatchling with manygo to cross-compile Go binaries into platform-specific wheels.

CI release (recommended)

Tag a release and push — the release-cli.yml workflow builds wheels for all platforms and publishes to PyPI automatically:

tag --prefix cli

To do this manually:

git tag cli/v0.1.0
git push origin cli/v0.1.0

The workflow builds wheels for: linux/amd64, linux/arm64, darwin/amd64, darwin/arm64, windows/amd64, windows/arm64.

Manual release

Build a wheel locally with uv. Set GOOS and GOARCH to cross-compile for other platforms (Go handles this natively — no cross-compiler needed):

# Build for current platform
uv build --wheel

# Cross-compile for a different platform
GOOS=linux GOARCH=amd64 uv build --wheel

# Upload to PyPI
uv publish

Versioning

Versions are derived from git tags with the cli/ prefix (e.g. cli/v0.1.0). The tag is parsed by internal/_version.py and injected into the Go binary via -ldflags at build time.
