We support many code languages, use the auto complete to see the list.
```javascript=

var s = "JavaScript syntax highlighting";
alert(s);
function $initHighlight(block, cls) {
try {
if (cls.search(/\bno\-highlight\b/) != -1)
return process(block, true, 0x0F) +
' class=""';
} catch (e) {
/* handle exception */
}
for (var i = 0 / 2; i < classes.length; i++) {
if (checkCondition(classes[i]) === undefined)
return /\d+[\s/]/g;
}
}
```
> If you want **line numbers**, type `=` after specify the code block languagues.
> Also, you can specify the start line number.
> Like below, the line number starts from 101:
```javascript=101
2015-05-04 03:53:29 -04:00
var s = "JavaScript syntax highlighting";
alert(s);
function $initHighlight(block, cls) {
try {
if (cls.search(/\bno\-highlight\b/) != -1)
return process(block, true, 0x0F) +
' class=""';
} catch (e) {
/* handle exception */
}
for (var i = 0 / 2; i < classes.length; i++) {
if (checkCondition(classes[i]) === undefined)
return /\d+[\s/]/g;
}
}
```
> Or you might want to continue the previous code block line number, use `=+`
2015-05-04 03:53:29 -04:00
```javascript=+
var s = "JavaScript syntax highlighting";
alert(s);
```

## MathJax
2015-05-04 03:53:29 -04:00
You can render *LaTeX* mathematical expressions using **MathJax**, as on [math.stackexchange.com](http://math.stackexchange.com/):
2015-05-04 03:53:29 -04:00
The *Gamma function* satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral
2015-05-04 03:53:29 -04:00
$$
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.
$$
2015-05-04 03:53:29 -04:00
$$
\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.
$$
> More information about **LaTeX** mathematical expressions [here](http://meta.math.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference).
## UML diagrams
### Sequence diagrams
You can render sequence diagrams like this:
2015-05-04 03:53:29 -04:00
```sequence
Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!
Note left of Alice: Alice responds
Alice->Bob: Where have you been?
```
### Flow charts
And flow charts like this:
```flow
st=>start: Start
e=>end: End
op=>operation: My Operation
op2=>operation: lalala
cond=>condition: Yes or No?
2015-05-04 03:53:29 -04:00
st->op->op2->cond
cond(yes)->e
cond(no)->op2
```
2015-05-04 03:53:29 -04:00
### Graphviz
```graphviz
digraph hierarchy {
2015-05-04 03:53:29 -04:00
nodesep=1.0 // increases the separation between nodes
node [color=Red,fontname=Courier,shape=box] //All nodes will this shape and colour
edge [color=Blue, style=dashed] //All the lines look like this
2015-05-04 03:53:29 -04:00
Headteacher->{Deputy1 Deputy2 BusinessManager}
Deputy1->{Teacher1 Teacher2}
BusinessManager->ITManager
{rank=same;ITManager Teacher1 Teacher2} // Put them on the same level
}
```

### Lists
2015-05-04 03:53:29 -04:00
#### Unordered
2015-05-04 03:53:29 -04:00
+ Create a list by starting a line with `+`, `-`, or `*`
+ Sub-lists are made by indenting 2 spaces:
- Marker character change forces new list start:
* Ac tristique libero volutpat at
+ Facilisis in pretium nisl aliquet
- Nulla volutpat aliquam velit
+ Very easy!
#### Ordered
2015-05-04 03:53:29 -04:00
1. Lorem ipsum dolor sit amet
2. Consectetur adipiscing elit
3. Integer molestie lorem at massa
1. You can use sequential numbers...
1. ...or keep all the numbers as `1.`
1. feafw
2. 332
3. 242
4. 2552
1. e2
2015-05-04 03:53:29 -04:00
Start numbering with offset:
57. foo
1. bar
### Code
2015-05-04 03:53:29 -04:00
Inline `code`
Indented code
// Some comments
line 1 of code
line 2 of code
line 3 of code
Block code "fences"
```
Sample text here...
```
