## Code block
|
|
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
|
|
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 `=+`
|
|
|
|
```javascript=+
|
|
var s = "JavaScript syntax highlighting";
|
|
alert(s);
|
|
```
|
|
|
|
### Blockquotes tags
|
|
> Using like below to specifiy your **name, time and color** to differ the blockquotes.

> [name=ChengHan Wu] [time=Sun, Jun 28, 2015 9:59 PM] [color=#907bf7]
|
|
> > Even support the nest blockquotes!
|
|
> > [name=ChengHan Wu] [time=Sun, Jun 28, 2015 10:00 PM] [color=red]

## MathJax
|
|
|
|
You can render *LaTeX* mathematical expressions using **MathJax**, as on [math.stackexchange.com](http://math.stackexchange.com/):
|
|
|
|
The *Gamma function* satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral
|
|
|
|
$$
|
|
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.
|
|
$$
|
|
|
|
$$
|
|
\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.
|
|
$$
|
|
|
|
> 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:
|
|
|
|
```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?
|
|
|
|
st->op->op2->cond
|
|
cond(yes)->e
|
|
cond(no)->op2
|
|
```
|
|
|
|
### Graphviz
|
|
```graphviz
|
|
digraph hierarchy {
|
|
|
|
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
|
|
|
|
Headteacher->{Deputy1 Deputy2 BusinessManager}
|
|
Deputy1->{Teacher1 Teacher2}
|
|
BusinessManager->ITManager
|
|
{rank=same;ITManager Teacher1 Teacher2} // Put them on the same level
|
|
}
|
|
```

### Lists
|
|
|
|
#### Unordered
|
|
|
|
+ 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
|
|
|
|
