I'm writing a series of blog posts, in which I write a #bytecode #compiler and a #virtualMachine for arithmetic in #Haskell. We explore the following topics in the series:

- Parsing arithmetic expressions to ASTs.
- Compiling ASTs to bytecode.
- Interpreting ASTs.
- Efficiently executing bytecode in a VM.
- Disassembling bytecode and decompiling opcodes for debugging and testing.
- Unit testing and property-based testing for our compiler and VM.
- Benchmarking our code to see how the different passes perform.
- All the while keeping an eye on performance.

The second post of the series that focuses on writing the #compiler is now out: https://abhinavsarkar.net/posts/arithmetic-bytecode-vm-compiler

Netencode: I’m currently building out my project of making a “better” structured language for use in UNIX-pipelines and shell scripting and the like.

It’s human-readable, but supports trivial generation with printf & wc, tagged values (sum types, Result<T>) and embedding arbitrary binaries without escaping due to being length-prefixed.

I think it’s pretty cool!
