Problem with these tools is, you have to spend time wrangling them instead of learning to write a lexer/parser yourself. A recursive-descent parser is a beautiful thing and can be implemented very quickly.

If you know basic programming (js/python), a day is more than enough to get the concept across using a tiny language. Could probably be done in an hour. The problem, always, is people are given terrible reading recommendations which ma

This is why I don't use the c std library for my compiler/vm projects. For the few functions you need, you build your own library that wraps the syscalls. And then you can distribute a binary that will run on Linux kernels going b

I am only criticizing python because I am actively using it. The node ecosystem and the rust one seem to have their own issues. I have zero interest in either of them so I haven't looked into them in detail. However, I have to deal wi

A bit baffling, IMO, the focus on GIL over actual python performance, particularly when you had so many examples of language virtual machines improving performance in that era. So many lost opportunities.

> There are efforts to speed it up Well, the extensions are going to complicate this a lot. A fast JIT interpreter cannot reach into a library and do its magic there the way HotSpot/V8 can with native Java/JS code.

My use of python is somewhat recent. But the two languages that I have used a lot of - Java and JS - have interpreters that were heavily optimized over time. I wonder why that never happened with python and, instead, everyone continues to w
