How to Install Hare Programming Language on Fedora 39/38/37 Linux

Hare is an innovative and modern programming language that aims to provide developers with a seamless and efficient coding experience. Its design philosophy revolves around simplicity, readability, and performance, making it an excellent choice for various applications. This introduction will delve into the unique features and benefits of the Hare programming language.

Key Features and Benefits of Hare:

  • Easy-to-learn syntax: Hare’s syntax is designed with simplicity and readability, making it accessible to beginners while still being versatile enough for experienced developers.
  • Static typing with type inference: Hare offers the best of both worlds, combining the safety of static typing with the convenience of type inference, making your code more robust and less prone to errors.
  • First-class functions and higher-order functions: Hare fully supports functional programming paradigms, allowing for cleaner and more expressive code through the use of first-class functions and higher-order functions.
  • Concurrency support: Hare has built-in support for concurrency and parallelism, enabling developers to manage multiple tasks and take advantage of multi-core processors efficiently.
  • Cross-platform compatibility: Hare is designed to be platform-agnostic, allowing you to write code that runs seamlessly on various operating systems, including Windows, macOS, and Linux.
  • Efficient memory management: Hare’s runtime system is optimized for efficient memory management, significantly reducing garbage collection overhead and improving overall performance.
  • Extensive standard library: Hare has a comprehensive standard library, offering a wide range of built-in functions and modules to facilitate rapid development and reduce the need for external dependencies.
  • Interoperability with other languages: Hare’s flexible and modular design allows easy integration with other programming languages, enabling leveraging existing libraries and frameworks to enhance your Hare projects.

As you can see, the Hare programming language offers unique features and benefits that make it an attractive choice for developers of all skill levels. In the following guide, we will demonstrate how to install Hare programming on Fedora Linux using CLI commands and the HARE COPR, allowing you to dive right in and start exploring the exciting world of Hare.

Section 1: Install Hare Programming Language

Step 1: Update Fedora

To ensure a smooth installation process and maintain good practice, updating your Fedora system before proceeding is essential. Updating your system minimizes the chances of encountering issues during the installation. To update Fedora, open your terminal and enter the following command:

sudo dnf upgrade --refresh

This command updates your system packages and refreshes the package metadata to reflect any recent changes.

Step 2: Import Hare Programming Language COPR

The recommended method for installing Hare on Fedora is to enable the COPR (Cool Other Package Repo) repository provided by sentry/hare. The COPR repository contains additional packages not officially part of Fedora but maintained by the community.

To enable the repositories for both QBE (a backend compiler) and Hare, execute the following commands in your terminal:

sudo dnf copr enable sentry/qbe -y
sudo dnf copr enable sentry/hare -y

Upon successful execution, you should see the following output at the end of the import log:

Repository successfully enabled.

This message indicates that the repositories have been added and are now available.

Step 3: Install Hare Programming Language

With the COPR repositories enabled, you can now install Hare and its associated components. To install Hare, the Hare compiler, and the QBE backend compiler, enter the following command in your terminal:

sudo dnf install hare harec qbe -y

This command installs the necessary packages for the Hare programming language, its compiler, and the QBE backend compiler. Once the installation is complete, you can use Hare for your development projects.

Section 2: Test Hare – Create Hello World Test

After installing Hare, it is a good idea to create a simple “Hello World” program to test the installation and ensure everything works correctly. If you’re new to Hare, it’s also a great opportunity to familiarize yourself with the language.

Step 1: Create a Hello World file

To begin, create a new file named helloworld.ha using a text editor of your choice. In this tutorial, we will use the nano text editor:

sudo nano helloworld.ha

Step 2: Write the Hello World code

Next, copy and paste the following Hare code into the helloworld.ha file:

use fmt;

export fn main() void = {
	fmt::println("Hello world!")!;

For users working with the nano text editor, press CTRL+O followed by CTRL+X to save and exit the file.

Step 3: Compile and run the Hello World program

Now, execute the following command to compile and run the Hello World program:

hare helloworld.ha

You should see the classic “Hello World” output if everything is set up correctly.

Section 3: Additional Hare Commands with Fedora Linux

How to Update Hare

To keep Hare up to date, you can use the standard DNF commands. Since Hare is installed from a repository, you will receive updates alongside your system updates. To check for updates manually, run:

sudo dnf update --refresh

How to Remove Hare

To uninstall Hare and its associated components, execute one of the following commands:

sudo dnf autoremove hare harec qbe -y

How to Disable the Hare COPR Repository

If you have no plans to reinstall Hare, it’s a good idea to disable the COPR repositories. To do this, run the following commands:

sudo dnf copr disable sentry/qbe -y
sudo dnf copr disable sentry/hare -y

Conclusion: Installing Hare on Fedora Linux

In this guide, we have successfully walked through installing the Hare programming language on Fedora Linux. We started by updating the system and then added the Hare and QBE COPR repositories. After that, we installed Hare and its associated components, such as the Hare compiler and the QBE backend compiler. Finally, we tested the installation by creating a simple “Hello World” program and covered essential commands for managing Hare on Fedora, including updating and removing the programming language.

Following these steps gives you a solid foundation for starting your journey with the Hare programming language on Fedora Linux. We encourage you to explore and utilize Hare in your programming projects and remember to consult the official documentation and resources to deepen your knowledge.
