Example use cases

Create a list out of files

The following Markdown:

# Overview of plugins

<?js
  const fs = require("fs")
  const dir = "./plugins"
  const links = []
  fs.readdirSync(dir).forEach(file => {
    const path = dir + "/" + file
    if (fs.statSync(path).isDirectory()) {
      links.push(`<li><a href="${path}/README.md">${file}</a></li>`)
    }
  })
  const html = `<ul>\n  ${links.join("\n  ")}\n</ul>`
  return html
?>

Should generate (assuming it was called from this repository):

<h1>Overview of plugins</h1>
<ul>
  <li><a href="./plugins/classes/README.md">classes</a></li>
  <li><a href="./plugins/gulp-pimd/README.md">gulp-pimd</a></li>
  <li><a href="./plugins/highlight/README.md">highlight</a></li>
  <li><a href="./plugins/html-injector/README.md">html-injector</a></li>
  <li><a href="./plugins/id/README.md">id</a></li>
  <li><a href="./plugins/preview/README.md">preview</a></li>
  <li><a href="./plugins/prism/README.md">prism</a></li>
  <li><a href="./plugins/showmore/README.md">showmore</a></li>
</ul>
