Asides config

[StephenPCG]

use meta to control asides

• for page and article, one can use asides to control which asides to show and in what order for individual pages:

title: awesome title
author: awesome author
asides: recentpost, categories, tags, ...

• if article.asides is not defined, use global config ARTICLE_ASIDES
• if page.asides is not defined, use global config PAGE_ASIDES
• for pages other than article or page, e.g. index.html, categories.html, etc., use global config INDEX_ASIDES
• if none of above is defined, use all

Due to merge conflict with branch sidebar-switch, I have merge that branch into this one.

This is a strange feature to control at post level. Is there are reason why this is not preferable to have as blog level setting?

Hi duilio, initially I just wanted to control it at page level (for per page), not for per post. The motivation is that, I don't want to show a sidebar for pages like "Biography", and "Recent Posts aside" is meaningless for pages like "Archive". For some special cases, I may want to add special aside for certain post, for example I need a "Article Background" aside for a specific post.

Anyway, I thinks this patch just provides possibility to control the sidebar. Without any configuration, it just works like before. But if anyone would like a fine grained control like me, he/she has the option.

ok, fine :-) I would just like two bits of docs in the readme file, i guess you can copy & paste what you've written in the description of this pull request.
