Docker with persistent storage

By default the database lives at `~/.blogwatcher-cli/blogwatcher-cli.db`. In Docker this is lost on container restart. Use `BLOGWATCHER_DB` or a volume mount to persist it:

# Named volume (simplest)
docker run --rm -v blogwatcher-cli:/data -e BLOGWATCHER_DB=/data/blogwatcher-cli.db ghcr.io/julientant/blogwatcher-cli scan

# Host bind mount
docker run --rm -v /path/on/host:/data -e BLOGWATCHER_DB=/data/blogwatcher-cli.db ghcr.io/julientant/blogwatcher-cli scan

Migrating from the original blogwatcher

If upgrading from `Hyaxia/blogwatcher`, move your database:

mv ~/.blogwatcher/blogwatcher.db ~/.blogwatcher-cli/blogwatcher-cli.db

The binary name changed from `blogwatcher` to `blogwatcher-cli`.

Notes

• Auto-discovers RSS/Atom feeds from blog homepages when no `--feed-url` is provided.
• Falls back to HTML scraping if RSS fails and `--scrape-selector` is configured.
• Categories from RSS/Atom feeds are stored and can be used to filter articles.
• Import blogs in bulk from OPML files exported by Feedly, Inoreader, NewsBlur, etc.
• Database stored at `~/.blogwatcher-cli/blogwatcher-cli.db` by default (override with `--db` or `BLOGWATCHER_DB`).
• Use `blogwatcher-cli <command> --help` to discover all flags and options.
