N/A
Do you want to contribute this yourself as a pull request? (don’t worry about it if you don’t want to/can’t — someone else can take care of it)
- Yes, I have already written code for it (link if available and feasible)
- Yes, I don’t have code ready yet (that’s okay!)
- No (that’s okay too!)
Does this feature affect backwards compatibility? If yes, in what way?
Not as far as I know.
Rationale and full description: (why should it be added to Nikola?)
It's fairly common to link to the index page rather than to individual posts, hence it makes sense to generate OpenGraph meta-data for that page as well. I'm not sure exactly how difficult it is to propagate this to all themes, but at least for the Bootstrap theme that I am using, it was straightforward to extend to base_template.tmpl with:
<!-- ${pagekind} -->
%if 'index' in pagekind or 'main_index' in pagekind:
<meta property="og:site_name" content="${blog_author}">
<meta property="og:title" content="${blog_title|h}">
<meta property="og:url" content="${abs_link(permalink)}">
<meta property="og:description" content="${description|h}">
<meta property="og:image" content="${abs_link('/assets/images/phoenix_logo.png')}">
<meta property="og:type" content="article">
%endif
Naturally, the asset image link would need to be changed somehow, perhaps by using the DEFAULT_PREVIEW_IMAGE, but other than that, the above should be pretty much usable as-is in any HTML template.
