Hi HN, I wrote this PiCo, a small register-based scripting language and virtual machine in C. This is a learning project. In the early stage I read Crafting Interpreters and learned a lot. Then I gradually changed the design toward register-based VM, module system, standard library, GC controls and etc. It is a small toy language, not a production-ready tool. I am making it complete enough that someone can play with it. I’d be happy to hear feedback.
