Installation

Linux

First, install choosenim. This program allows you to install and upgrade Nim easily.

Visit https://nim-lang.org/install_unix.html and follow the instructions. You need to execute a script that installs choosenim for you.

Once you have choosenim, here is how to use it:

$ choosenim update self       # updates choosenim
$ choosenim update stable     # installs latest stable Nim
$ choosenim stable            # selects stable version
$ nim -v                      # version info

Make sure to extend your PATH with the following folder:

export PATH=$PATH:$HOME/.nimble/bin

Windows

Visit https://nim-lang.org/install_windows.html and download Nim in .zip format. I suggest extracting it to the root of the C: drive (example: C:\nim-2.2.8).

Then, add these folders to your PATH (in this order):

c:\Users\<user_name>\.nimble\bin

C:\nim-2.2.8\bin

Testing if everything works

Create a simple program called hello.nim :

Compile and run:

$ nim c hello.nim
$ ./hello
hello nim

Installing Atlas

Atlas is a package cloner that manages project dependencies in an isolated deps/ directory. We don't need it at the beginning while learning the language. When you install Nim, then the binary atlas is in the bin/ folder. However, atlas is not present in ~/.nimble/bin. Everything else is there, except this one.

If you want it to be there, you can install it with nimble:

$ nimble install https://github.com/nim-lang/atlas

Note that "nimble install atlas" wouldn't work since atlas is not in nim-lang/packages.

Thus, under Linux it's enough to add ~/.nimble/bin to your PATH.
