A simple gem to parse X-Robots-Tag HTTP headers according to Google X-Robots-Tag HTTP header specifications.
Add this line to your application's Gemfile:
'robots_tag_parser', git: 'https://github.com/GSA/robots_tag_parser'
And then execute:
$ bundle
Get rules applying to all user agents:
ers = { 'X-Robots-Tag' => ['noindex,noarchive', 'googlebot: nofollow'] }
tsTagParser.get_rules(headers: headers)
'noindex', 'noarchive']
Get rules applying to specific user agents (which include generic rules):
ers = { 'X-Robots-Tag' => ['noindex,noarchive', 'googlebot: nofollow'] }
tsTagParser.get_rules(headers: headers, user_agent: 'googlebot')
'noindex', 'noarchive', 'nofollow']
