Defined in:
lib/html2rss/status.rb

Overview

Shared RSS generator / JSON Feed user_comment formatter string.

Exposed publicly via FeedResult#status. Safe to log without reading articles. Stable telemetry payload for cross-repo consumers (e.g. html2rss-web observability). Tallies and counters are validated and frozen at construction (including Marshal load).

    articles kept after deduplication

  • dedup_dropped (Integer) (defaults to: 0) —

    number of articles removed by deduplication

  • selected_strategy (Symbol, nil) (defaults to: nil) —

    concrete strategy that succeeded under :auto (else nil)

  • attempt_count (Integer) (defaults to: 0) —

    auto-fallback attempt count (0 when not under :auto)

  • strategy_attempts (Array<Hash>) (defaults to: []) —

    auto-fallback attempt hashes (empty outside :auto)

Returns:

.scraper_name(klass) ⇒ String

Returns short scraper label for tallies / generator text.

Parameters:

  • klass (Class, #to_s) —

    scraper class

Returns:

Instance Method Details

#to_generator_comment ⇒ String

Formats the RSS generator string and JSON Feed user_comment. Scraper-focused only — auto strategy summary stays on #to_h, not this string. Omits the (scrapers: …) clause when tallies are empty.

Returns:

  • (String)

  counts = scraper_tallies.map { |name, count| "#{name} (#{count})" }
  "html2rss V. #{version} (scrapers: #{counts.join(', ')})"
end

#to_h ⇒ Hash{Symbol => Object}

Observability hash for web (+scraper_status+). Omits empty/absent optional keys: :scraper_tallies when empty, :selected_strategy when nil, :attempt_count when zero, :strategy_attempts when empty. Data members remain available via readers even when omitted here.

Returns:

  • (Hash{Symbol => Object}) —

    always :version (String), :dedup_dropped (Integer); optionally :scraper_tallies, :selected_strategy, :attempt_count, :strategy_attempts
