Iridium

So You Want to Build a Language VM - Part 17 - Basic Threads

Adds executing a program in separate OS threads

Intro

Hey everyone! In this tutorial, we’re going to start adding in multithreading to the Iridium VM. Please make sure you are starting from this point in the code: https://gitlab.com/subnetzero/iridium/tags/0.0.16. Going forward, I’m going to make a tag per tutorial so that everyone starts from a common point. === A Note on Assumed Knowledge I write these tutorials target towards more advanced users. I sometimes skip small steps, such as "add in this line to file X".

So You Want to Build a Language VM - Part 16 - String Constants And More

Two-pass assembler, using and printing string constants, and other loose ends

Home Stretch

This is going to be a longer post. In it, we’ll wrap up our two-pass assembler, add a PRTS opcode for printing, and tie up some other loose ends. At the end, we should have an interpreter with a good amount of functionality and a simple assembly language. We are, of course, far from done with the project. I want to work on a different tutorial series for a bit, then we’ll continue with Iridium. === Quick Change Add the following dependencies in your Cargo.toml. We’ll need them later:

So You Want to Build a Language VM - Part 15 - Assembler CLI Improvements

Makes the CLI interface a bit more robust and useful

CLI Improvements

Having to start the interpreter, then type .load_file, etc is cumbersome. Let’s change it so that the VM tries to execute the file given to it as an argument. There’s a super handy-dandy crate called clap in Rust that will make this trivial. The behavior we want is:
