Jasmine, A rust-like programming language that compiles to Java
I had recently completed the first year of my Computer Science class at school and will begin my second year soon. My schools' class forces the use of Java programming language, and I absolutely hated it. So, over the course of a little less than a month, I wrote my own programming language, in Rust (objectively best programming language), using pest, to be as similar to Rust as possible, but compiling to Java.

What is the state of the art for creating domain-specific languages (DSLs) with Rust?
I second pest.rs. Using it is fairly intuitive and there's also a live playground on their website which is great for quickly developing and testing your AST (abstract syntax tree) parser for whatever language you're implementing.

Finding a Crate to Help with Terminal Program Interface
This is where you'll run into trouble. People who write parsing-related Rust crates generally write things like pest that expect their syntax to be defined completely at compile time so the parser can be run through the compiler's optimizers for best performance.

What is your opinion about lifetime of data generated from a parsing
For now I have used pest to generate an AST that borrows from the given input. But if I can manage to make the parser generic over the return type it may be worth a refactoring.
- Is there a parsing library (lexer?) which can handle generic tokens?

Yeah, we all know what you're good for...
just use Melody

I've created a Python module for constructing Regex patterns in a more computer programming-familiar way, so you don't have to re-learn Regex each time you use it!
How do you feel about projects such as melody?

Why does it have to be like this?
I found this beauty a while ago
