When working on preparing data for the covid.observer site, I discovered a couple of interesting findings, which I did not notice earlier or did not pay much attention to it.

Yesterday, I launched covid.observer, the website displaying Coronavirus statistics. Unlike the most sources, this site tries to deliver the same data to avoid panic.

The goal of this chapter is to build a better interpreter using all the achievements of the previous three chapters. The new interpreter will be able to work with numbers of different types and to perform different arithmetic operations with variables. To make it even better, we’ll start with a very useful addition — comments.

I’ve re-published a bunch of interviews that I took about five years ago: brian d foy Audrey Tang Flávio Glock Damian Conway Stevan Little Carl Mäsak Reini Urban There’s a couple of more, dating even earlier history. Maybe one day they will appear here too 🙂
In this chapter, we will create a program that can evaluate simple arithmetic expressions such as 3 + 4 or 3 – 3 * 7. We’ll start from the simplest equations with two operands and will work until we can introduce parentheses.

In the following two chapters, we will temporary leave the compiler created in the previous chapter, and will be working on a separate helper project, a calculator. It is an interesting thing on its own, and we will explore it on an isolated example. In the next chapters, it will be integrated to the interpreter.

Let’s start exploring the power or Raku’s grammars and regexes from a simple interpreter program that parses and executes the following tiny program. I will call this language Lingua.

Before the GitHub 02/02/2020 Archive program, I uploaded all my books published by DeepText to github.com/ash/books. I hope it will be frozen and archived for the future generations :-D.

Some time ago, I published an article about using NativeCall in Raku to call functions written in C. Today, let’s see how you can call simple functions written in C++ or in Fortran.

I’d like to try how Raku can help in building a simple stack-oriented language.
