Installing Stack Haskell in Manjaro can be quite an interesting journey. Whether you’re a seasoned Haskell developer, or just starting out, having the correct development environment is crucial to your workflow. In this article, I’ll guide you through the process of setting up Stack Haskell in Manjaro – a fantastic, user-friendly operating system, perfect for programmers.
The Haskell Programming Language and Stack
Haskell is a statically-typed, purely functional programming language with a rich variety of features. Renowned for its advanced type system and emphasis on writing robust, safe programs, it has been increasingly used in both academia and industry.
-- A simple definition of a function in Haskell add :: Int -> Int -> Int add x y = x + y
Stack is a powerful tool for Haskell. Essentially, it allows us to manage Haskell projects with reproducible builds, taking care of the package dependencies automatically.
The installation procedure is relatively straight-forward on Manjaro, although there exist a few steps that need to be followed correctly to set up the environment.
We start by updating our system with the command:
sudo pacman -Syu
Next, we install stack with the pacman package manager:
sudo pacman -S stack
After successfully installing Stack, you can then setup your Haskell project workspace.
Setting Up a Haskell Project
A Haskell project can be setup with Stack effortlessly. Stack requires a .yaml configuration file which includes all the details related the project dependencies.
stack new my-project cd my-project stack setup
Here, “my-project” would be your project name. The “stack new” command generates a new project with its respective files, whereas “stack setup” gets the correct compiler version for the project.
Library and Function
Haskell’s standard library is packed with a wide array of functions. Ranging from working with data structures such as lists and maps, to intricate type manipulation, it provides a robust foundation for any Haskell programmer.
import Data.List -- Function to sort a list using built-in Haskell functions sortList :: Ord a => [a] -> [a] sortList = sort
A good habit would be to explore different libraries and functions, as Haskell’s rich ecosystem can often provide elegant solutions to complex problems.
In conclusion, in this piece, we have installed and setup Haskell’s stack in Manjar. This should give you a solid starting point to explore more about Haskell and functional programming in general. Do make sure to read Haskell documentation and explore its vast array of libraries and packages.
