InfluxData Documentation Tooling CLI

Usage: docs <command> [options]

Commands:
  audit --products <p>                Audit documentation coverage
  create <draft> --products <p>       Create new documentation
  edit <url>                          Edit existing documentation
  release-notes <from> <to>           Generate release notes
  placeholders <file>                 Add placeholder syntax to code blocks

Product Targeting:
  --products accepts product keys OR content paths:
    influxdb3_core        or  /influxdb3/core
    influxdb3_enterprise  or  /influxdb3/enterprise
    telegraf              or  /telegraf

  --repos accepts direct repository paths or URLs (alternative to --products)

Configuration:
  Uses environment variables for configuration.
  See scripts/docs-cli/config/README.md for full documentation.

  Quick setup:
    1. (Optional) Copy config/.env.example to .env
    2. Authenticate with GitHub: gh auth login
    3. Run commands

Examples:
  # Audit documentation (using product key or path)
  docs audit --products influxdb3_core
  docs audit --products /influxdb3/core --version v3.3.0

  # Create new content
  docs create drafts/feature.md --products influxdb3_core
  docs create drafts/feature.md --products /influxdb3/core,/influxdb3/enterprise

  # Edit existing page
  docs edit /influxdb3/core/admin/databases/

  # Generate release notes
  docs release-notes v3.1.0 v3.2.0 --products influxdb3_core

  # Add placeholders to code blocks
  docs placeholders content/influxdb3/core/admin/databases.md

  # Get command help
  docs audit --help
  docs create --help
  docs edit --help
  docs release-notes --help
