Auto header for each page

[liulex]

Take docisfy as an example:

With loadSidebar enabled, in docs/_sidebar.md, we have:

- Getting started
 - [Quick start](/quickstart)
 - [Writing more pages](/more-pages)
 - [Custom navbar](/custom-navbar)
 - [Cover page](/cover)

...

The first line of /quickstart is # Quick start, and the first line of /custom-navbar is # Custom navbar, etc.
It would be great if we do not have to manually write these lines, since they can be inferred from the sidebar.

It has 3 advantages at least:

• Save a line in each subpage, of course.
• Whenever we want to change the header for a subpage, we only need to modify it in the sidebar, not both places. And the inconsistency can be avoided naturally.
  • For example, at the moment, docsify has Writing more pages for /more-pages in the sidebar, while the first line of /more-pages.md is More pages. Such inconsistency may not be desireable.
• Be consistent with the behavior of Github Wiki.
  • In Github Wiki, a page named Changelog, which is actually a file Changelog.md, will have the header 'Changelog' automatically. We do not have to add a line # Changelog in the content. See here for an example.
  • If this feature is implemented, we will be able to directly use Github Wiki for docsify. For example, the md file for the link above is 'https://raw.githubusercontent.com/wiki/liulex/Snipaste-Feedback/Changelog.md'. We can alias /Changelog to it. Then we can have a Github Wiki (for community edit) and a doscify generated site at the same time!

In case I haven't made myself clear, the logic of this feature (maybe named autoHeader) is:

If loadSidebar and autoHeader are both enabled, for each link in _sidebar.md, prepend a header to the page before converting it to html.

For example, if [Quick start](/quickstart) is in _sidebar.md, we prepend a line # Quick start into /quickstart.md before we render /quickstart.md into html.

Thanks! Now I only need to maintain the wiki pages! 🎉🎉🎉

Cool. Good idea!

If you put all the pages on the wiki, you only need to configure the basePath.

$docsify = {
  basePath: 'https://raw.githubusercontent.com/wiki/liulex/Snipaste-Feedback/'
}

I tried, but I cannot alias the sidebar. The following config does not work:

$docsify = {
  alias: {
      '/zh-cn/_sidebar': 'sidebar_zh.md'
  }
}

And since the file names of Github Wiki are case-sensitive, I would still need to write some aliases after I set basePath. So I am satisfied the current configs. 😄
