A Customizable Markdown Library for rendering Markdown in Adaptive Cards.

Custom markdown rules for your application is possible now without any regex learning.

To use, add the markdown-formatter.js to your html

<script src="https://unpkg.com/js-markdown-formatter"></script>

Then see Usage for futher details

Check these files for the sample usage.

example.html - has the basic usage with adaptive cards.

customRegexExample.html - check this file for passing custom regex.

• '_italic_' will result in 'italic'.
• '**bold**' will result in 'bold'.
• '[Title](link)' will result in Title.
• '- bullet 1\r - bullet2\r - bulltet 3' will result in following way

   . bullet 1 
   . bullet2
   . bullet 3
  

• '1. numbered 1\r 2. numbered2\n 3. numbered 3' will result in following way

  1. numbered 1 
  2. numbered2
  3. numbered 3
  

To replace or to be added with default config.

•   {
        type: 'italic',
    	styles: [],
    	pattern: ['-'],
    	patternType: 'symmetric',
    	groups:1,
    }
  

  The above pattern will render '-italic-' in 'italic'.

•   {
    	type: 'bullet',
    	styles: [],
    	pattern: ['\\$[\\s]+((.*?)[\\n|\\r](?=\\$[\\s]+)|(.*?)$)'],
    	patternType: 'custom',
    	groups: 1,
    },
  

  The above pattern will convert 'bullet list $ Item 1.1\r$ Item -2.2-\r$ Item 3\r' in following way:

  bullet list
  . Item 1.1
  . Item -2.2-
  . Item 3
  

• One can create custom markdown based on project need and render it within text.

• One can also send the whole regex itself with pattern type custom to have complete control on markdown to apply regex on text and render it

<script src="https://unpkg.com/js-markdown-formatter"></script>

// use it in onProcessMarkdown of adaptivecard instance.
adaptiveCard.constructor.onProcessMarkdown = function(text, result) {
	result.outputHtml = MarkdownFormatter.render(text);
	result.didProcess = true;
}

Extra Features: User can also send their custom regex and styles also to apply on text.

//[Optional] user's custom config to be added to default configs
MarkdownFormatter.setCustomMarkdownRegex([{
                type: 'bullet', // this will replace the default bullet config with user specified config.
                styles:{
                    start: "<ul>",
                    end: "</ul>"},
                pattern: ['$', '\\r|\\n'],
                patternType: 'start-end',
                groups: 1
            },
            {
                type: 'italic',
                styles:{
                    start: "<i>",
                    end: "</i>"},
                pattern: ['-'],
                patternType: 'symmetric',
                groups:1,
            }]);
