This helper exists to make it easy to output a URL for a twitter page. Ghost has access to twitter page names/usernames for both users and for the site itself. When used without passing a username, the helper will look for a twitter username in the current template context, and then fallback to using @site.twitter. If there is no twitter username set, the helper will output nothing at all. If you pass a variable or string to the helper, it will concatenate the value with the full url for a twitter page.

Examples

Output the author’s twitter, using an author block: 
{{#foreach posts}}
  {{#author}}
    {{#if twitter}}<a href="{{twitter_url}}">Follow me on twitter</a>{{/if}}
  {{/author}}
{{/foreach}}
