Using the following code, I get working output:
<html> <head> <script type="text/javascript" src="/js/showdown.js"></script> </head> <body> <script type="text/javascript"> var converter = new Showdown.converter(); alert(converter.makeHtml('*test* abc')); </script> </body> </html> Returning <p><em>test</em> abc</p>
I would now like to add an extension. The github page suggests this can be done with:
<script src="src/extensions/twitter.js" /> var converter = new Showdown.converter({ extensions: 'twitter' }); However, modifying my code to:
<html> <head> <script type="text/javascript" src="/js/showdown.js"></script> <script type="text/javascript" src="/js/twitter.js"></script> </head> <body> <script type="text/javascript"> var converter = new Showdown.converter({ extensions: 'twitter' }); alert(converter.makeHtml('*test* abc')); </script> </body> </html> Produces the error
"Uncaught Extension 'undefined' could not be loaded. It was either not found or is not a valid extension." Adding the following code (as listed under the Filter example)
var demo = function(converter) { return [ // Replace escaped @ symbols { type: 'lang', function(text) { return text.replace(/\\@/g, '@'); }} ]; } Produces an error Uncaught SyntaxError: Unexpected token (
I would like to create an extension like this one https://github.com/rennat/python-markdown-oembed to interpret a , but it's unclear how to begin adding this support.

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.
EDIT
It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.
var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" I submitted a pull request to update this.
