# Collector Documentation Sync

Automated synchronization of OpenTelemetry Collector component documentation
from the ecosystem registry to opentelemetry.io.

## Overview

This automation:

1. Clones the
   [opentelemetry-ecosystem-explorer](https://github.com/open-telemetry/opentelemetry-ecosystem-explorer)
   repository to access the collector registry
2. Reads component metadata from `ecosystem-registry/collector/`
3. Updates data registry files in `data/collector/`
4. Updates version information in `data/collector-versions.yml`
5. Creates/updates pull requests with the changes

## Version Management

Component links dynamically reference versions from
`data/collector-versions.yml`:

```yaml
# data/collector-versions.yml
core: v0.146.1
contrib: v0.146.0
```

The automation:

- Updates this file with the latest release versions
- Markdown tables use Hugo shortcodes:
  `{{< component-link name="otlp" type="receiver" repo="core" >}}`
- Hugo reads versions from the data file at build time

**To update versions for a new release:**

1. Run the automation script (updates `data/collector-versions.yml`)

## Local Development

### Setup

```bash
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install Python dependencies (including dev dependencies)
cd scripts/collector-sync
uv sync --all-extras
```

### Running Locally

```bash
cd scripts/collector-sync
uv run python -m documentation_sync

# Or with --no-update to skip cloning/updating ecosystem-explorer
uv run python -m documentation_sync --no-update
```

### Testing

**Prerequisites:** Ensure dev dependencies are installed with
`uv sync --all-extras`.

```bash
# Run all tests
npm run test:collector-sync

# Or run individually
npm run check:collector-sync        # pytest
npm run check:collector-sync:types  # mypy type checking
npm run check:collector-sync:lint   # ruff linting

# Auto-fix linting issues
npm run fix:collector-sync:lint
```

## Fork Testing

Contributors can test the automation in their forks using
`.github/workflows/collector-sync-fork.yml`.

**To test in a fork:**

1. Push changes to your fork
2. Go to Actions → "Sync Collector component docs (fork)"
3. Click "Run workflow"

The fork workflow uses `GITHUB_TOKEN` instead of the otelbot app token.

## Markers in Documentation

Documentation pages must have marker comments for updates to work:

```markdown
