What does it do?

Recently tested hexo.io against facebook linter. Apparently, the value for "og:locale" must be in language_TERRITORY format, so "en" is invalid. Here is a list of valid values.

If og:locale is not specified, fb defaults to "en_US".

(The following note is only applicable if you're not using en-US locale. It's optional for en-US users.)

If the language value (regardless from config or front matter) is not in language-TERRITORY format, "og:locale" will not be added.

If the language value in _config is just two characters (e.g. "en", "fr"), then you need to append territory value, e.g. "en-GB", "fr-CA". you also need to update the filename of the language file (e.g. "en.yml" -> "en-GB.yml") of your theme.

Alternatively, you could also set <%- open_graph({language: 'en-GB'}) %> in your theme layout.

How to test

git clone -b ogp-locale https://github.com/curbengh/hexo.git
cd hexo
npm install
npm test
