The pest book is finally complete now! 🎆 (sort of) · pest-parser pest · Discussion #1105

I aimed to keep it in line with the "demonstration of the Rust ecosystem" goal, so it can also be a great introduction to Rust for beginners who are looking for a fun project to work on. It's not perfect, but that's part of the fun! It leaves room for potential language extensions (to make the AWK clone more complete) and optimizations up to the reader as a follow-up.
every time I see a rust thing I go look and there's another MIT license every time
I'm not sure why this surprises you. MIT OR Apache is standard for Rust libraries.
Not everyone wants to copyleft their code. People write these libraries with different goals in mind, and sometimes someone wants to use their own library in their own closed source project.
Then they can release it publicly under the GPL and then privately license it to their employer under hopefully specific terms, ideally for a fee. There’s no good reason to let for-profit companies reap the value out of FOSS.
I know, it's pretty awesome right? It's one of the highlights of the community in my opinion.
