'''Title Slide'''

||Welcome to the Spoken tutorial on '''Installation of Rust on Linux.'''
|- 
|| Show Slide: 

'''Learning Objectives'''
|| In this tutorial, we will learn how to
* Install Rust on Ubuntu Linux
* Set up an Integrated Development Environment 
* Run a “Hello World” Rust program

|- 
|| Show Slide:

'''System Requirements'''
|| To record this tutorial, I am using
* Ubuntu Linux OS version 22.04
* Visual Studio Code

|- 
|| Show Slide:

'''Installation Requirements'''
|| For the installation of Rust

* A working internet connection is required

|- 
|| Show Slide: 

'''About Rust'''
||
* Rust is a systems programming language and similar to C++
* It prioritizes performance, memory safety, and parallelism. 
* Rust offers features like guaranteed memory safety without needing a garbage collector.

|- 
||Press '''ctrl''', '''alt''' and '''t''' keys.
||Open the terminal by pressing '''ctrl''', '''alt''' and '''t''' keys simultaneously.
|- 
|| > '''curl --version'''


'''>sudo apt install curl'''

|| First we need to check whether '''curl''' is installed in our system

For that, Type '''curl --version'''

If you see information about '''curl''', it means '''curl''' is installed.

If you get an error, you have to install curl.

Type, '''sudo apt install curl'''

Enter the password if prompted.
|- 
|| Type '''curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh'''

'''curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh'''
|| Once curl is installed, type the following command.

You will see a list of options. 

Press 1 to proceed with default installation.

This will install modules and packages like '''cargo''', '''rustfmt''', '''clippy'''.

These will be useful for development and writing code.
|- 
|| Cursor at the prompt.
||Next, we will set up an '''Integrated Development Environment(IDE)'''.
|- 
|| Open '''web''' '''browser '''

Type [https://www.nsnam.org/releases/ https://]code.visualstudio.com</u>

|| Open any web browser.

In the address bar type this link.

Visual Studio code page opens. 

Let us download and install '''Visual Studio Code'''.
|- 
|| Click on the '''Download''' button 

Click on '''.deb for Ubuntu.'''

|| Click on the '''Download''' button on the top right corner of the window.

You can see options for various operating systems.

I will download a '''.deb ''' file for ''' Ubuntu'''.
|- 
|| '''Right click''' on the file select '''open with software install.'''

Click on the '''install''' button.

Type the system password.
|| Let us go to the''' Downloads folder''' and locate the ''' .deb file.'''

Right click on the file and select '''open with software install'''.

Click on the '''install''' button.

Enter the system password to authenticate.

Once the installation is complete, close the window.
|- 
|| 
|| Let us open the '''Visual Studio code'''.

Go to '''Show Applications ''' on the bottom left of your screen.

In the search bar, type '''Visual Studio code.'''

Click on '''Visual Studio Code ''' to open the window.
|- 
||  Locate rust-analyzer and click on Install button.
|| On the left toolbar, click on '''Extensions icon '''.

The '''Extensions panel '''opens. 

In the ''' Search bar ''' type, '''rust-analyzer ''' and Press '''Enter'''.

A list of options will appear.

Locate ''' rust-analyzer''' and click on '''Install''' button.

Once the installation is complete a blue tick mark appears.

'''Rust analyzer''' extension is used to autocomplete the code. 

It makes the code more readable.
|- 
|| In the terminal, type

> rustc –version

1.80.1
|| We can verify the installation by running these commands on the terminal:

'''rustc --version '''

We can see the '''Rust compiler''' version that has been installed.
|- 
||>cargo --version
|| '''Type,'''

'''cargo --version '''

This will show the package manager and build system version.
|- 
||> rustup –version
|| Type

'''rustup --version '''

This shows the rustup toolchain manager version.
|- 
|| 
||You have to restart the system after the rust installation is completed.
|- 
||
|| After installing Rust and its extensions, it is important to understand a few key components.

They are '''Rust compiler''', '''Cargo''', and the '''Toolchain Manager'''.
|- 
|| '''Slide:'''

'''Rust Compiler'''

|| Now we will learn about''' Rust Compiler.'''
* '''rustc '''is the Rust compiler
* It is responsible for translating the Rust code into executable binaries.
* This process involves checking for errors and optimizing your code for performance.

|- 
|| '''Rustup: The Toolchain Manager'''

|| 
* Rustup is a toolchain manager that helps to manage '''Rust''' versions and tools. 
* It allows you to easily install and switch between different versions of '''Rust'''. 

|- 
|| '''Open the text editor'''

'''fn main() {'''

'''println!("Hello, World!");'''

'''}'''

|| Now, let's write our first '''Rust''' program. 

Open the text editor. 

Type the following code.

|- 
|| '''Highlight according to narration'''
|| In this program, we will print “Hello, World!” 

Save the file by pressing '''Ctrl''',  '''S'''.

Type the file name as '''Helloworld.rs''' and save it on the '''Desktop'''.
|- 
|| '''>cd Desktop'''

'''> rustc Helloworld.rs'''

'''> ./Helloworld '''
|| Switch back to the terminal.

Go to the folder where we have saved the rust program

Type '''cd Desktop'''.

Then type,

'''rustc Helloworld.rs'''

This will compile the program.

Type ./'''Helloworld''' to run the program.

We can see the output: '''Hello, World!''' 
|- 
||
||This shows we have successfully installed Rust and compiled and executed a program.

Let us summarize. 

In this tutorial, we have learnt to
* Install Rust on Ubuntu Linux
* Set up an Integrated Development Environment 
* Run a “Hello World” program
