Version 1.0.13
https://github.com/allejo/jekyll-anchor-headings
"Be the pull request you wish to see in the world." ~Ben Balter
Usage:
{% include anchor_headings.html html=content anchorBody="#" %}
Parameters:
* html (string) - the HTML of compiled markdown generated by kramdown in Jekyll
Optional Parameters:
* beforeHeading (bool) : false - Set to true if the anchor should be placed _before_ the heading's content
* headerAttrs (string) : '' - Any custom HTML attributes that will be added to the heading tag; you may NOT use `id`;
the `%heading%` and `%html_id%` placeholders are available
* anchorAttrs (string) : '' - Any custom HTML attributes that will be added to the `<a>` tag; you may NOT use `href`, `class` or `title`;
the `%heading%` and `%html_id%` placeholders are available
* anchorBody (string) : '' - The content that will be placed inside the anchor; the `%heading%` placeholder is available
* anchorClass (string) : '' - The class(es) that will be used for each anchor. Separate multiple classes with a space
* anchorTitle (string) : '' - The `title` attribute that will be used for anchors
* h_min (int) : 1 - The minimum header level to build an anchor for; any header lower than this value will be ignored
* h_max (int) : 6 - The maximum header level to build an anchor for; any header greater than this value will be ignored
* bodyPrefix (string) : '' - Anything that should be inserted inside of the heading tag _before_ its anchor and content
* bodySuffix (string) : '' - Anything that should be inserted inside of the heading tag _after_ its anchor and content
* generateId (true) : false - Set to true if a header without id should generate an id to use.
Output:
The original HTML with the addition of anchors inside of all of the h1-h6 headings.
