Hey everyone,
Just a quick tip – to embed Haxe code, type three “backtick” characters then the word “haxe”
Afterward, type your code.
On the next line afterward, do three more backtick characters.
It should look like this (when you are typing):
```haxe
var hello = "World";
```
It works for a lot of languages:
###haxe
package;
class HelloWorld {
public function new () {}
}
###as3
package {
public class HelloWorld {
public function HelloWorld () {
}
}
}
###xml
<hello world="" />
###bash
echo "Hello World"
and many more 
Happy chatting, and thanks everyone!
