Markdown Monster Mermaid Sample

Mermaid 2

Mermaid is a JavaScript based parsing engine that allows you to embed blocks of graph markup into a page. Markdown Monster supports two different approaches using either code block or HTML tag syntax to embed the mermaid blocks.

@icon-warning Internal Preview Limitations

Note the MM internal preview can't properly display or refresh all chart types, but you can preview in your system browser via Shift-F12 to see proper representation.

Sequence Diagram

You can use a mermaid code block:

View XmlElementsAndAttributes.cs
void Main()
var doc = new XmlDocument();
doc.LoadXml("<d><t>This is &amp; a \"test\" and a 'tested' test</t></d>");
var node = doc.CreateElement("d2");
node.InnerText = "this & that <doc> and \"test\" and 'tested'";
var attr = doc.CreateAttribute("note","this & that <doc> and \"test\" and 'tested'");
View TestDynamic.prg
DO wwDynamic
DO wwJsonSerializer
loCust = CREATEOBJECT("TestClass")
loItem = CREATEOBJECT("wwDynamic",loCust)
*loItem = CREATEOBJECT("wwDynamic")

Markdown is a plain text representation of HTML typically. Markdown works using a relatively small set of easy to type markup mnemonics to represent many common document centric HTML elements like bold, italic, underlined text, ordered and unordered lists, links and images, code snippets, tables and more. This small set of markup directives is easy to learn and quick to type in any editor without special tools or applications.

In the past I've been firmly planted in the world of rich text editors like Word, or using a WYSIWYG editor on the Web, or for Blog Editing using something like Live Writer which used a WYSIWYG editor for post editing. When I first discovered Markdown a number of years a
