Academic is designed to give technical content creators a seamless experience. You can focus on the content and Academic handles the rest.
**Highlight your code snippets, take notes on math classes, and draw diagrams from textual representation.**
On this page, you'll find some examples of the types of technical content that can be rendered with Academic.
## Examples
### Code
Academic supports a Markdown extension for highlighting code syntax. You can enable this feature by toggling the `highlight` option in your `config/_default/params.toml` file.
```python
import pandas as pd
data = pd.read_csv("data.csv")
data.head()
```
renders as
```python
import pandas as pd
data = pd.read_csv("data.csv")
data.head()
```
### Math
Academic supports a Markdown extension for $\LaTeX$ math. You can enable this feature by toggling the `math` option in your `config/_default/params.toml` file.
To render *inline* or *block* math, wrap your LaTeX math with `$...$` or `$$...$$`, respectively.
Example **math block**:
```tex
$$\gamma_{n} = \frac{
\left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T
\left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}
{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2}$$
```
renders as
$$\gamma_{n} = \frac{ \left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T \left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2}$$
Example **inline math** `$\nabla F(\mathbf{x}_{n})$` renders as $\nabla F(\mathbf{x}_{n})$.
Example **multi-line math** using the `\\\\` math linebreak:
```tex
$$f(k;p_0^*) = \begin{cases} p_0^* & \text{if }k=1, \\\\
1-p_0^* & \text {if }k=0.\end{cases}$$
```
renders as
$$f(k;p_0^*) = \begin{cases} p_0^* & \text{if }k=1, \\\\
1-p_0^* & \text {if }k=0.\end{cases}$$
### Diagrams
Academic supports a Markdown extension for diagrams. You can enable this feature by toggling the `diagram` option in your `config/_default/params.toml` file or by adding `diagram: true` to your page front matter.
An example **flowchart**:
```mermaid
graph TD
A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]
```
renders as
```mermaid
graph TD
A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]
```
An example **sequence diagram**:
```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
loop Healthcheck
John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts!
John-->>Alice: Great!
John->>Bob: How about you?
Bob-->>John: Jolly good!
```
renders as
```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
loop Healthcheck
John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts!
John-->>Alice: Great!
John->>Bob: How about you?
Bob-->>John: Jolly good!
```
An example **Gantt diagram**:
```mermaid
gantt
section Section
Completed :done, des1, 2014-01-06,2014-01-08
Active :active, des2, 2014-01-07, 3d
Parallel 1 : des3, after des1, 1d
Parallel 2 : des4, after des1, 1d
Parallel 3 : des5, after des3, 1d
Parallel 4 : des6, after des4, 1d
```
renders as
```mermaid
gantt
section Section
Completed :done, des1, 2014-01-06,2014-01-08
Active :active, des2, 2014-01-07, 3d
Parallel 1 : des3, after des1, 1d
Parallel 2 : des4, after des1, 1d
Parallel 3 : des5, after des3, 1d
Parallel 4 : des6, after des4, 1d
```
An example **class diagram**:
```mermaid
classDiagram
Class01 <|-- AveryLongClass : Cool
<<interface>> Class01
Class09 --> C2 : Where am i?
Class09 --* C3
Class09 --|> Class07
Class07 : equals()
Class07 : Object[] elementData
Class01 : size()
Class01 : int chimp
Class01 : int gorilla
class Class10 {
<<service>>
int id
size()
}
```
renders as
```mermaid
classDiagram
Class01 <|-- AveryLongClass : Cool
<<interface>> Class01
Class09 --> C2 : Where am i?
Class09 --* C3
Class09 --|> Class07
Class07 : equals()
Class07 : Object[] elementData
Class01 : size()
Class01 : int chimp
Class01 : int gorilla
class Class10 {
<<service>>
int id
size()
}
```
An example **state diagram**:
```mermaid
stateDiagram
[*] --> Still
Still --> [*]
Still --> Moving
Moving --> Still
Moving --> Crash
Crash --> [*]
```
renders as
```mermaid
stateDiagram
[*] --> Still
Still --> [*]
Still --> Moving
Moving --> Still
Moving --> Crash
Crash --> [*]
```
### Todo lists
You can even write your todo lists in Academic too:
```markdown
- [x] Write math example
- [x] Write diagram example
- [ ] Do something else
```
renders as
- [x] Write math example
- [x] Write diagram example
- [ ] Do something else
### Tables
Represent your data in tables:
```markdown
| First Header | Second Header |
| ------------- | ------------- |
| Content Cell | Content Cell |
| Content Cell | Content Cell |
```
renders as
| First Header | Second Header |
| ------------- | ------------- |
| Content Cell | Content Cell |
| Content Cell | Content Cell |
### Asides
Academic supports a [shortcode for asides](https://sourcethemes.com/academic/docs/writing-markdown-latex/#alerts), also referred to as *notices*, *hints*, or *alerts*. By wrapping a paragraph in `{{%/* alert note */%}} ... {{%/* /alert */%}}`, it will render as an aside.
```markdown
{{%/* alert note */%}}
A Markdown aside is useful for displaying notices, hints, or definitions to your readers.
{{%/* /alert */%}}
```
renders as
{{% alert note %}}
A Markdown aside is useful for displaying notices, hints, or definitions to your readers.
{{% /alert %}}
### Spoilers
Add a spoiler to a page to reveal text, such as an answer to a question, after a button is clicked.
```markdown
{{</* spoiler text="Click to view the spoiler" */>}}
You found me!
{{</* /spoiler */>}}
```
renders as
{{< spoiler text="Click to view the spoiler" >}} You found me! {{< /spoiler >}}
### Icons
Academic enables you to use a wide range of [icons from _Font Awesome_ and _Academicons_](https://sourcethemes.com/academic/docs/page-builder/#icons) in addition to [emojis](https://sourcethemes.com/academic/docs/writing-markdown-latex/#emojis).
Here are some examples using the `icon` shortcode to render icons:
```markdown
{{</* icon name="terminal" pack="fas" */>}} Terminal
{{</* icon name="python" pack="fab" */>}} Python
{{</* icon name="r-project" pack="fab" */>}} R
```
renders as
{{< icon name="terminal" pack="fas" >}} Terminal
{{< icon name="python" pack="fab" >}} Python
{{< icon name="r-project" pack="fab" >}} R
