Extensibility

This plugin overrides some default behaviors of how markdown-it plugin renders the markdown into html, to integrate with the Hexo ecosystem. It is possible to override this plugin too, without resorting to forking the whole thing.

For example, to enable unsafe links (which is disabled by default):

hexo.extend.filter.register('markdown-it:renderer', function(md) {
  const { config } = this; // Optional, parse user config from _config.yml
  md.validateLink = function() { return true; };
});

// Specify custom function in plugin option
const { slugize } = require('hexo-util');
const opts = hexo.config.markdown.anchors;
const mdSlugize = (str) => {
  return slugize(str, { transform: opts.case, ...opts });
};

hexo.extend.filter.register('markdown-it:renderer', function(md) {
  md.use(require('markdown-it-table-of-contents'), {
    includeLevel: [2,3,4],
    slugify: mdSlugize
  });
});

Save the file in "scripts/" folder and run Hexo as usual.

Refer to markdown-it API documentation.
