# What is Visual Studio Code :question:

**Visual Studio Code** (VS Code) is a lightweight but powerful source code editor which runs on your desktop and is available for Windows, macOS and Linux.

It has a rich ecosystem of extensions for languages (such as C++, Fortran, Java, Python, etc) and runtimes (Git, Jupyter, etc)

VSC is one of the most popular and powerful text editors used by software engineers today 
> free, open-source and [available](https://code.visualstudio.com/download) for macOS, Windows and Linux :+1:

# VS Code 

You can install Visual Studio Code from the web link [here](https://code.visualstudio.com/download)

`wget` the **deb** package then `dpkg -i code*.deb`

That's it ! :smiley:

---

## Install extensions

- Python
- Jupyter

# Jupyter Notebook in VS Code

Create a new Juyter Notebook

![h:200](assets/new_ipynb.png)

Fill the first cell

```python
import numpy as np
```

---

Try to run the cell

> you must choose a Python environment first (Python 3.6)

If :boom: ... maybe you must install a missing extension !

So open a **terminal** in VS Code an do

```bash
sudo apt install python3-pip
```

---

Now, install the missing Python extension ... 

```bash
pip instal numpy
```

![h:350](assets/vscode_add_ext.png)

... and run the cell again: great, it's OK now :smiley:

## Let's try a full notebook example

Install Git : `sudo apt install git -y`

Now clone this **Git repository**

```bash
git clone https://gogs.elic.ucl.ac.be/pbarriat/learning-vscode
```

> You don't already know what's Git :question:
> Shame on you ! :confounded:
>
> **It's not to late**: take a look here
> https://gogs.elic.ucl.ac.be/TECLIM/Git_Training

Now open the file `example.ipynb`

---

The first cell implies you must install some requirements

To run this example, install the extensions below

```bash
pip install netCDF4
sudo apt install libgeos-dev libgdal-dev
pip install cartopy
```

Now, try to run all the cells of this notebook :exclamation:

# VS Code nice extensions

- `Tabnine` : code faster with AI code completions
- `Regex Previewer` : shows the current regular expression's matches
- `Modern Fortran` : Fortran syntax is missing in built-in version
