Instance Method Details

#call ⇒ Hash

Parse +Gemfile.lock+ and classify notable gems.

Returns +{ error: message }+ for any rescued +StandardError+ — including a missing or unreadable lockfile, malformed content, or any other runtime exception — so callers always receive a controlled hash rather than an unhandled exception.

Returns:

  • (Hash) —

    gem analysis with +:total_gems+, +:ruby_version+, +:notable_gems+, and +:categories+ on success; or +{ error: String }+ on any rescued +StandardError+
