Learn Bosque Programming

By: Sebastian Kaczmarek, Joel Ibaceta

Overview of this book

Bosque is a new high-level programming language inspired by the impact of structured programming in the 1970s. It adopts the TypeScript syntax and ML semantics and is designed for writing code that is easy to reason about for humans and machines. With this book, you'll understand how Bosque supports high productivity and cloud-first development by removing sources of accidental complexity and introducing novel features. This short book covers all the language features that you need to know to work with Bosque programming. You'll learn about basic data types, variables, functions, operators, statements, and expressions in Bosque and become familiar with advanced features such as typed strings, bulk algebraic data operations, namespace declarations, and concept and entity declarations. This Bosque book provides a complete language reference for learning to program with Bosque and understanding the regularized programming paradigm. You'll also explore real-world examples that will help you to reinforce the knowledge you've acquired. Additionally, you'll discover more advanced topics such as the Bosque project structure and contributing to the project. By the end of this book, you'll have learned how to configure the Bosque environment and build better and reliable software with this exciting new open-source language.

Writing a "Hello, World!" program

First things first: let's create a folder for our first program. You can do this directly from VSC or by using your favorite terminal. Since we have just set up our IDE to play with Bosque, I recommend that you use it. First, click File | New File. A new tab named Untitled-1 should appear—click File | Save (or press Ctrl + S on the keyboard) in order to rename it and save it at your desired location. Save the file under the name main.bsq. If you prefer to do this using a terminal, open it and type the following command:

$ mkdir first-project
$ cd first-project

Now, open VSC in the directory you have just created and create a file named main.bsq, as described earlier.

Once you have created the main.bsq file, fill it with the following content and save it:

namespace NSMain;
entrypoint function main(): String {
        return "Hello, world!";
}

I will explain this code...
