*[data-markdown] - use markdown, sometimes, in your HTML

*[data-markdown] userscript

I just put some markdown in ur HTML

In prototypes and HTML-based slide decks, it's pleasant to write in markdown sometimes and avoid all those angle brackets.

So the idea is you're operating in an HTML environment but a few shortcuts would help so use markdown here and there.

To use:

1. Install this userscript (click the 'raw' link for the user.js file below).

• It automatically adds github flavored markdown's to every page.

2. Add data-markdown attributes to any tags where you're gonna use markdown within. (see example)

(As this requires some clientside js and can trigger FOUC, this is not for production use)

data-markdown.user.js

function X0() {
  if (!window.Showdown) {
    setTimeout(X0, 200);
  } else {
    [].forEach.call( document.querySelectorAll('[data-markdown]'), function(elem){
      // strip leading whitespace so it isn't evaluated as code
      var md = elem.textContent.replace(/(^\s+)|(\n\s+)/g,'\n')
      , html = (new Showdown.converter()).makeHtml(md);

      // here, have sum HTML
      elem.innerHTML = html;
    });
  }
}

var el;

el = document.createElement("script");
el.type = "application/javascript";
el.src = "https://raw.github.com/github/github-flavored-markdown/gh-pages/scripts/showdown.js";
document.body.appendChild(el);

el = null;

el = document.createElement("script");
el.type = "application/javascript";
el.innerHTML = "(" + X0.toString() + ")();";
document.body.appendChild(el);
