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.
