oss-metrics-kit 0.0.3

Unified toolkit to fetch, normalize, score, and export OSS contribution metrics.

oss-metrics-kit

Toolkit to fetch, normalize, score, and export OSS contribution data — end to end.

Status: early stage; CLI and core models are available and expanding.

What you can do in 5 minutes

• Analyze a GitHub user’s activity and get a simple score summary.
• Save scores into SQLite or Postgres for dashboards.
• Export scores to Parquet for data tools.
• Optionally, let an LLM suggest a rules TOML from your events.

Quick Start (Beginner-friendly)

1. Install the package (pick one)

• pip (recommended for users): pip install oss-metrics-kit
• uv (recommended for devs): uv venv .venv && source .venv/bin/activate && uv sync --dev

2. Set a GitHub token (read-only is enough)

export GITHUB_TOKEN=ghp_xxx   # or GH_TOKEN

3. Analyze your account and print results

ossmk analyze-user <your_github_login> --since 90d --api auto --out -

4. Save scores (SQLite for a quick try)

ossmk analyze-user <your_github_login> --out scores.json
ossmk save sqlite:///./metrics.db --input scores.json

5. Export scores to Parquet (for data tools)

pip install "oss-metrics-kit[exporters-parquet]"
ossmk analyze-user <your_github_login> --out parquet:./scores.parquet

That’s it. See Getting Started for more step‑by‑step details.

Getting Started (Step-by-step)

If you are new to Python tools or GitHub APIs, read:

• docs/getting-started.md — a gentle, copy‑paste tutorial with expected outputs.
• docs/usage.md — command reference with CI examples.

Install (development)

Use a virtual environment (venv/conda/uv) and install editable:

• pip install -e . or python -m pip install -e .
• Check CLI help with ossmk --help

Note: Running ossmk requires installation. For direct runs during development, either install editable or set PYTHONPATH=src and run the entry point.

Dev environment (uv recommended)

1. Install uv

• macOS/Linux: curl -LsSf https://astral.sh/uv/install.sh | sh
• Homebrew: brew install uv
• pipx: pipx install uv

2. Create venv and sync deps

• uv venv .venv → source .venv/bin/activate
• uv sync --dev
• All extras: uv sync --dev --extra all

3. Run

• ossmk --help (in venv) or uv run ossmk --help

Install from PyPI (users)

• Stable: pip install oss-metrics-kit
• With Postgres exporter: pip install "oss-metrics-kit[exporters-postgres]"

Examples

• Persist scores to Postgres:

export OSSMK_PG_DSN="postgresql://user:pass@host:5432/db"
ossmk analyze-user <your_github_login> --save-pg

• Load proprietary rules (TOML):

export OSSMK_RULES_FILE=/absolute/path/to/private/rules.toml
ossmk analyze-user <your_github_login> --out -

Usage (overview)

• Version: ossmk version
• Analyze GitHub user (parallel fetch, since/GraphQL aware): ossmk analyze-user <login> --since 90d --api auto --out -
• Fetch repo events: ossmk fetch --provider github --repo owner/name --since 30d --out -
• Save scores: ossmk save postgresql://... --input scores.json or ossmk save sqlite:///./metrics.db --input scores.json

Storage is selected via DSN (Postgres/SQLite). Parquet output is available as an optional exporter.

LLM-assisted rules (optional)

• Suggest rules: ossmk rules-llm --input events.json --provider openai --model gpt-4o-mini --out rules.toml
• Extras: pip install "oss-metrics-kit[llm-openai]" or oss-metrics-kit[llm-anthropic]
• See docs/LLM_RULES.md

Security & operations

• Keep tokens in env (GITHUB_TOKEN/GH_TOKEN) and never log them.
• Rate limiting is a backend responsibility; a simple example is provided at ossmk.security.ratelimit.RateLimiter (use Redis for production).
• Store private rule TOMLs outside the repo and point OSSMK_RULES_FILE to them. rules=auto|default will load it.
• Optional features (Postgres/Parquet/LLM) are separated as extras.

See docs/INTEGRATION.md for backend integration. Development typing/lint policy: docs/dev.md. Detailed usage: docs/usage.md. A beginner tutorial is in docs/getting-started.md.

Environment variables

• GITHUB_TOKEN or GH_TOKEN: GitHub API token (required)
• OSSMK_RULES_FILE: path to a private rules TOML (optional)
• OSSMK_PG_DSN or DATABASE_URL: Postgres DSN (if persisting)
• REDIS_URL: Redis rate limiter (optional)
• OSSMK_MAX_SINCE_DAYS: max backward window for since (default 180)

Publishing to PyPI (maintainers)

See docs/RELEASING.md for the full release flow (versioning, tagging, CI-based publish, and manual alternatives).

Design highlights

• src/ layout with py.typed for type distribution.
• Thin CLI with Typer; business logic in ossmk.core.
• Providers/exporters/storage/rules via entry points.

Troubleshooting

• pip._vendor.tomli.TOMLDecodeError: Invalid initial character...

  • Cause: malformed leading section in pyproject.toml
  • Fix: ensure first section is [build-system], reinstall pip install -e .

• ossmk: command not found

  • Cause: not installed or wrong environment activated.
  • Fix: pip install -e . in the repo, and activate the same environment.
  • With uv: uv sync --dev then source .venv/bin/activate, or uv run ossmk --help.
