To quote the website of this programming language:

Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada, and Modula.

This gives us a pretty good idea that the language meets everything needed to create modern applications.

Like all modern languages, it has versions for Windows, Linux, macOS, and BSD. This makes it possible to run on almost all current systems. This also makes it possible for the programmer to choose the environment where he feels best.

Nim is an object-oriented language with a syntax similar to Python‘s with even similar characteristics.

So, let us get to work.

Installing Nim programming language on Ubuntu 20.04 / Debian 10

In Ubuntu 20.04 / Debian 10 Nim is included in the official repositories. Therefore the installation becomes quite simple and is summarized too in

:~$ sudo apt install nim

However, this method is not recommended because the latest Nim version is not installed.

So there is another method that allows us to install the latest stable version, but also the development version.

To install it, there is a script that we have to download and run but first, we have to install the Debian compilation packages.

So, open a terminal and execute the following command

:~$ sudo apt install build-essential

When the installation is finished, we will be able to execute the installation script.

In case curl is not installed you can install it with the following command:

:~$ sudo apt install curl

Then have Nim installed. We have to make it available throughout the system.

So edit the ~/.profile file:

:~$ nano ~/.profile

And add the following:

export PATH=/home/your-home/.nimble/bin:$PATH

Replace "your-home" with your username or home.

Save the changes and close the file.

Appley the change by running:

:~$ nim -v

Testing Nim Installation

Now it is time to test if the installation has worked.

So we’ll create the classic test program by displaying a message. This will serve the purpose.

The code files for the Nim language, they have a nim extension. So we will create one:

:~$ nano hello.nim

And within this file add the following content:

echo "Hi, Osradar"

Save the changes and close the file.

Now, compile the source file to generate the executable binary.

:~$ nim c hello.nim

 Hint: 14211 LOC; 3.140 sec; 15.887MiB peakmem; Debug build; proj: /home/angelo/hello.nim; out: /home/angelo/hello [SuccessX]

Remember that you have to specify the source file but also the full path.

Then, run it as follows:

~$ ./hello

So now we know that nim works and you can start working with him.
