BlogWatcher CLI

Quick Orientation

• Use the Cobra entry point in cmd/blogwatcher/main.go and internal/cli/.
• Route business logic through internal/controller and persistence through internal/storage.
• Use scanning pipeline packages in internal/scanner, internal/rss, and internal/scraper.
• Remember the default SQLite path is ~/.blogwatcher/blogwatcher.db and is created on demand.

Run Commands

• Run locally with go run ./cmd/blogwatcher ....
• Build with go build ./cmd/blogwatcher.

Change Workflow

1. Add or adjust CLI commands in internal/cli/commands.go (Cobra options, arguments, output formatting).
2. Put non-trivial logic in internal/controller so the CLI stays thin and testable.
3. Update storage or schema in internal/storage/database.go and adjust model conversion in internal/model if needed.
4. Modify scanning behavior in internal/scanner and its helpers (internal/rss, internal/scraper).
5. Update or add tests under internal/ or cmd/ for every feature change or addition.

Test Guidance

• Run tests with go test ./....
• If you add a feature, add tests and any necessary dummy data.
• Keep tests focused on CLI behavior, controller logic, and scraper/RSS parsing outcomes.

Output Conventions

• Preserve user-friendly CLI output with colors and clear errors.
• When listing posts available for reading, always include the link to each post in the output.
• Keep error handling consistent with existing exceptions (BlogNotFoundError, BlogAlreadyExistsError, ArticleNotFoundError).
